Polymer liquid waterproofing Blockade

Reliable and environmentally friendly polyurethane mastic for seams
Our company offers polyurethane sealing mastic for a wide range of purposes for waterproofing work indoors and outdoors

The reliability of many buildings largely depends on how reliably they are protected from moisture. First of all, this applies to objects that are constantly exposed to water: bathrooms, bathrooms, foundations, balconies, swimming pools. One of the most reliable means of waterproofing is polyurethane mastic for seams.

One-component polyurethane mastic - composition and properties

One of the most effective methods escape from unnecessary water - liquid waterproofing. It is also successfully used for coating protective layer open surfaces and to prevent moisture from appearing in hard-to-reach places. Polyurethane sealing mastic creates a uniform, seam-free and therefore reliable coating. Mastic represents liquid material based on polyurethane resins, which, when exposed to air, tend to polymerize and form a durable, highly elastic waterproofing layer.

“Blockade” is a polyurethane mastic, user reviews of which indicate excellent adhesion to any surface. One-component polyurethane mastic has the following advantages:

° It is an environmentally friendly product and after polymerization does not emit substances harmful to humans;
° The material is highly resistant to aggressive chemicals, ozone, ultraviolet radiation, microorganisms or gasoline;
° Mastic is not afraid of low and high temperatures, is resistant to abrasion and retains its properties even with sudden changes in external conditions;
° The material is vapor-tight and does not allow it to accumulate between the base and the coating;
° The mastic has high elasticity, which prevents cracks from appearing in any weather conditions.
°
° How is polyurethane mastic used for seams?
°
° Polymer liquid waterproofing Blockada has a wide range of uses from complex reinforced concrete structures to tanks and swimming pools. Polyurethane roofing mastics have proven themselves well on flat roofs, balconies or terraces. As a waterproofing layer under tiles or screeds and protective coating For the floors of garages and outbuildings, polyurethane floor mastic is used. The material can be safely used in contact with food and drinking water.
° Polyurethane mastic is sold in ready-to-use packages. It is enough just to mix it until smooth, and clean the working surface from debris or cement dust. Application can be done by machine spraying or manually with a roller. Foam tools should not be used in the work process.

During the construction of this cottage, a number of mistakes were made, which led to leaks across the entire area of ​​the roof being used. Repeated attempts to eliminate the problem with traditional roofing materials did not yield results. Since the contractor was running out of time to complete the project, it was decided to apply liquid waterproofing BLOCKADE. The application was carried out by our craftsmen using specialized equipment for airless spraying Graco Mark 5. This technique allows you to apply the material under high pressure up to two hundred bar, without the participation of air, without the expense of re-spraying, delivering the material only to the point where it is required at the moment.

Surface preparation before application included cleaning the surface from leaves and removing dust. The metal slopes were removed because the bulk of the leaks were underneath them. The existing roofing material was not dismantled, since BLOKADA, having high fluidity and adhesion, does not require an ideal surface. The first layer is a primer; the primer was prepared from liquid waterproofing on site, according to the instructions.

The second layer was applied on the same day, after about three hours,

after the primer layer has dried. The calculated thickness was 1 mm.

Since it was the end of autumn and the object was located in a pine forest, as a consequence high humidity and heavy dew on horizontal surfaces, we decided to apply a third layer after two days. To ensure one hundred percent evaporation of liquids from the material and complete polymerization. In the warm season, 2 hours is enough for interlayer drying. After applying the second, final layer 1 mm thick on horizontal surfaces, the vertical seams and joints of SIP panels were sealed along which moisture flowed first into the hidden cavities of the floors and from there into interior spaces buildings. The uniqueness of BLOKADA liquid waterproofing, in my firm belief, is that we have the ability to deliver material to almost any crevice, including internal, hidden cavities through which water finds a loophole. Another enormous advantage of this material is its fluidity! It follows the path of water, filling and sealing absolutely all joints and cracks. Despite the borderline application temperatures, BLOKADA Liquid Roofing solved the problem of leaks. Thanks to liquid waterproofing, the contractor managed to complete the interior finishing and deliver the project on time. Foreman of the waterproofing section Robert Robertovich Sahakyan.

The concept of a liquid roof
It is no secret that the roof is considered the most important element of a structure, regardless of its functional purpose. No construction can be completed without it. For this reason, the materials used to create this part of the house are required to have the maximum degree of reliability, as well as resistance to precipitation of any kind, be it rain, snow or hail.

It is liquid roofing that is considered the best remedy protecting the roof of an industrial building, apartment building or private building from destructive corrosion due to temperature changes and exposure to sunlight. It is considered an innovative building material that has all the characteristics necessary for a roof.

This article will help you understand many issues related to liquid roofing. We will look at the varieties of this wonderful material, its technical characteristics, as well as the specifics of installation and subsequent care. The article will discuss all the advantages and disadvantages of the roofing material, which is initially a liquid.

This material is often called liquid rubber. It is classified as a new product among materials used to insulate a room from moisture. In other words, liquid roofing is nothing more than a chemical mixture of special polymer additives with an acrylic binder.

The main area of ​​application is roofing. But this building material can also be used for repairs of much larger construction projects, including bridges, tunnels and some sections of roads.

Liquid rubber is able to perfectly protect concrete, wood, brick, screed, flooring, covering of old roofs ( Maintenance roofs), installation of new roofs, metal against corrosion. It can also be used during the repair of surfaces that originally had other materials. Numerous examples prove how widespread the use of this wonderful building material is. Liquid roofing, unique in its characteristics, is used in almost all areas of construction. Liquid roof photo

This popularity can be explained by the fact that this material has excellent characteristics. It is unlikely that any other material is capable of maintaining physical characteristics for at least fifteen years. During the experiments, it was possible to find out that liquid roofing can remain unchanged for about fifteen years. And at the same time, it does not contain any moisture, nor sudden changes in temperature conditions and other climatic changes.

Roofing in liquid form is called rubber largely for the reason that it has qualities similar to rubber, which significantly distinguishes it from others. building materials. Meanwhile, liquid roofing is capable of independently restoring its structure and appearance, which makes it extremely unique in terms of efficiency. Even if there is minor damage, the rubber will return to its original shape after some time. Other materials used in roof repairs do not achieve such a chic effect.

Advantages and minor disadvantages of liquid roofing
This coating is considered the most advanced in terms of technological method of reliable surface protection. Mostly liquid roofing material is applied to a previously prepared, clean base. But meanwhile, this material can be used both as a separate roofing covering and as an excellent companion for other materials.

The main property of the material is adhesiveness. Liquid roofing interacts well with various working surfaces. Second positive quality roofs are resistant to sudden changes in weather conditions. In addition, it is not susceptible to ultraviolet radiation and other aggressive factors that can destroy the roof. This material will last for a long time, because with a small amount of liquid roofing, you can cover a fairly large working area with it. Liquid roofing price

Liquid roofing looks very aesthetically pleasing, because after hardening it has no seams or roughness that could subsequently cause destruction of the treated surface. The material is extremely elastic and durable. And we must not forget about the excellent waterproofing properties.

Repairing the surface with the liquid roofing Blockade is easy and convenient. All that is necessary for this is to cover the damaged area with a new layer. And after it hardens, you will not be able to find where the damage was. When repairing, the material does not require open flame and can be applied to the work surface with a roller, brush, or airless spray.

The disadvantages of this material include the rather high price relative to bituminous materials. But bituminous materials are very sensitive to solvents and liquids, sunlight and temperature changes, and other derivatives that contain oil and its derivatives. The price of liquid roofing Blockade is compensated due to the low consumption, relatively bitumen waterproofing.

Based on the above, we can come to the conclusion that liquid roofing Blockade has more benefits than disadvantages. This makes it stand out from other building materials.

Application of polymer-based roofing
This type of building material can be widely used for different types of roofs, regardless of the purpose of the building. The roofing material looks ideal on industrial construction sites and on private homes. And thanks to a number of unique properties of such a roof, it can be used not only as protection, but also as a separate material for the roof of a building. So it is not at all surprising that liquid roofing is gaining more and more fans around the world every year.

Subtleties of working with liquid rubber on a flat roof
Often, such building material is used as a waterproofing material in the construction and repair of industrial buildings, apartment buildings, etc. Their characteristic– is the presence flat roof. The specifics of applying liquid roofing depend on the type and quality of the working surface itself. We will pay special attention to applying this versatile material to a flat work surface.

If you want the end result to be of high quality and satisfy all needs, the rubber should be applied to a clean roof. In this case, the roof may not be completely flat, but it is necessary to ensure that there are no large unevennesses and, especially, unnecessary objects on it. This will ensure uniform distribution of liquid rubber at the same level. This is the only way the liquid rubber will look great, and the surface itself will have full waterproofing properties.

The smoothness of the final surface depends on the equipment and application technologies used during the work. For example, if you use a high-pressure sprayer and apply liquid roofing to an almost smooth work surface, the result will be a completely smooth roof that has no seams and looks like a protective membrane.

But equipment with low pressure will not give such a result, but can only ruin the roof, wasting consumables. Moreover, the appearance of tubercles of varying heights is possible, which will significantly reduce the degree of attractiveness of the roof. Therefore, it is extremely important, even if it is not possible to pre-level the surface, it is best to use a screed before starting spraying.

The consumption of working material also depends on the type and characteristics of the surface being treated. So, for example, if liquid rubber is applied to slabs, its consumption will be significantly greater than when processing a flat surface. For this reason, experts advise pre-reinforcing all joints using a primer, which will help get rid of joints between the slabs. It will be even better if you first lay sheets of geotextile. The optimal use of liquid roofing is its application to a surface pre-treated with a screed. This will help achieve a great appearance and preserve the original aesthetic and physical properties material.

Roofing Blockade is an ideal solution for all types of roofs
Liquid roof is a new word among many building materials. Its chemical composition is characterized by the presence of polyurethane elastomers. Initially, this type of roofing was used only for the needs of the military, helping to cover strategically important objects with material that made it possible to hide them from prying eyes. However, as often happens, the inventions of the military became available to ordinary citizens who managed to appreciate all the advantages of this new material. Buy liquid roofing.

Thanks to the initially high requirements set by military personnel, liquid rubber is now a material with unusually high physical qualities, which primarily include reliability and wear resistance. In most of its properties, this material is similar to other types of rubber. However, in some cases it has much higher rates.

Liquid roofing is simply a godsend for creating a beautiful appearance for any type of roof. Today this material is used in almost all areas of construction, where a significant degree of protection is required from the materials used. This type of roofing can be used together with other materials, or used as a separate material for the roof. Having tried liquid roofing once, you can see for yourself how excellent it is as a building material, how durable, unique in appearance and reliable it is.

Advantages of liquid roofing
There is probably no country in the world with the same diametrically opposite climatic conditions as ours. The climate is mild in the European zone and harsh in the Far North. Many regions of Siberia and the Far East constantly experience significant fluctuations in average daily temperatures. The range of such fluctuations can be up to 20 degrees.

Naturally, not every construction and construction equipment can withstand such harsh conditions. finishing material. A sharp temperature change invariably leads to stretching - compression of the material, its deformation, the appearance of cracks, rupture, etc. Such changes are especially noticeable on the roofing.

One of the most economical and frequently used roofing coverings– built-up roofing. Ruberoid and others bitumen roofs very cheap, this attracts buyers. But it’s not for nothing that they say that the miser pays twice. Already on next year Such a roof needs to be repaired when used in harsh weather conditions.

Liquid roofing is a fundamentally new direction in the field of roofing materials. The basis of such a roof is liquid rubber. The coating does not require preheating or melting; it is the so-called “cold type” of roofing sheet.

Of course, the cost of such a coating will be higher than when using a built-up roof. But this is understandable. Liquid roofing allows you to forget about restoration, repair and replacement of the roof of your house for 20 years or more, while roofing felt will have to be changed many times more often. So it turns out that liquid roofing ultimately turns out to be much more profitable and preferable than roofing felt.

The undeniable advantages of this material include:

-​ Easy installation;

- Excellent adhesion to any type of coating;

- High resistance to sun, water, precipitation, fire;

- Ideal material for covering curved surfaces and geometrically complex roofs;

- Light weight;

- No need to use special tools and fasteners;

Long service life

Thanks to the lack harmful substances, this roofing is also an environmentally friendly material.

In addition, instead of the usual black color, liquid roofing can be produced in a multi-colored version. So your home will now not only be reliably protected from rain and snow, but will also become aesthetically attractive.

In our climate, liquid roofing cannot always be used. This depends on the fact that Russia has different latitudes and different temperature zones. The company Voskhozhdeniye has developed an all-season roofing covering called Blockada. Liquid roofing can be used in cities such as Novosibirsk, Yakutsk, Vorkuta, Murmansk, Nefteyugansk, Arkhangelsk, Irkutsk, Krasnoyarsk, Petrozavodsk and other cities of Russia. Liquid roofing Blockada has proven itself to be excellent. An indispensable waterproofing material when applied at low temperatures. The temperature for applying liquid roofing is from minus 20 to plus 35 degrees Celsius.

For installing a new roof or repairing a used roof, an excellent waterproofing material is the liquid coating Blockade. This modern material is made on the basis of a polymer binder. It can be applied to any roof surface. The blockade serves as a reliable final coating that protects the surface from the effects of natural phenomena. If the roof leaks at the joints and seams, then a liquid roof will reliably protect it from moisture penetration and exposure to sunlight. This material is applied to rolled surfaces, slate, cement and wood. In all cases, liquid roofing becomes a reliable protection for the roof of a house, terrace, garage, veranda and other objects.

The company IC "VOSKHOZhDENIE" is a reliable supplier of polymer waterproofing to the country's construction markets. Blockade insulation is much more reliable and durable than bitumen-based roll insulation. After all, when installing rolled materials, joints remain that can cause moisture to penetrate into the room. In addition, under the influence of sunlight, bitumen gradually breaks down. Liquid roofing material covers the surface evenly, leaving no chance for precipitation to penetrate.

Insulation from this manufacturer is used not only for roofing work, but also for covering the foundation, which reliably protects walls from dampness, as well as for insulation basements. Today, Blockade is the most reliable and high-quality type of protection of premises from moisture penetration. On the company’s website, anyone can order liquid waterproofing in required quantity and the material will be delivered directly to the construction site.

The company offers favorable discounts for wholesale buyers. Liquid waterproofing is widely used for waterproofing balconies, loggias, bathrooms, walls, floors and roofs. This environmentally friendly material enjoys well-deserved consumer trust due to its impeccable quality and affordable price. The client can pick up the goods using his own transport, or it will be delivered by the company’s courier service. Payment is made in any form convenient for the buyer.

The use of waterproofing such as Blockade will provide the owner of the premises with a cozy and comfortable stay for a fairly long period. Reliable insulation will help create a normal microclimate in the house, eliminating the presence of mold and dampness. Since waterproofing does not require special effort and over a long period of time, construction labor costs are significantly reduced. If you order it in an online store, you can save significant part their Money. The OSM exhibition presents the best examples of liquid waterproofing Blockada.

The company's website contains a video of the installation of liquid waterproofing with step-by-step instructions. This video demonstrates the entire process of preparing the material and the surface on which it will be applied and the actions of the work performers. Thanks to this video material, you can apply the material to the required surface yourself.

Polyurethane waterproofing

Waterproofing of roofs and other construction sites
The durability and successful operation of any building structure is directly related to the creation of optimal humidity and temperature conditions for it. Condensation, which forms, for example, in places where there is no roof waterproofing, can not only penetrate the insulation and spoil its quality, but also get directly into the living space, onto the surface of the concrete or screed. Liquid polymer “Blockade” will help to reliably protect walls, ceilings, floors and other parts of the building from moisture. Buy polyurethane waterproofing

Polyurethane mastic for waterproofing Blockade is an effective waterproofing for floors, foundations, walls, roofs.
In terms of functional parameters, ease of use and versatility, the “Blockade” mastic has no analogues in the world. This is the most advanced insulation composition to date, created using space technology. Just 24 hours after application, this floor waterproofing completely polymerizes, forming thin layer, on which you can easily lay tiles or any other flooring. This product has many advantages:
· Exceptional versatility. “Blockade” is used in construction work on any surface: floors, basements, walls and foundations. With its help, even large-sized pools can be waterproofed easily and quickly.
· Environmentally friendly and odorless. There is no bitumen in the mixture.
· High whiteness, allowing the use of an insulation layer under decorative paint of any shade. In addition, “Blockade” is well tinted in desired color.
Ability to reflect ultra-violet rays and high heat resistance. With the help of such a coating, high-quality waterproofing of balconies and outbuildings is ensured. Polyurethane mastic works at temperatures of surrounding surfaces up to +120ºС and is superior to bitumen coatings in this indicator.
· Excellent ductility and flexibility. The insulation layer stretches well and therefore does not form microcracks when the slabs settle.
Liquid polyurethane waterproofing of a foundation, floor or other surface is applied using any convenient method: brush, roller or airless spray. It does not need to be oxidized like bitumen or heated to achieve good insulating properties as a surface. The resulting polymer coating is durable and has excellent ductility. Polyurethane waterproofing price

Bathroom waterproofing buy
Residents of high-rise buildings are familiar firsthand with the problems that can result from improper waterproofing of a bathroom or toilet. Therefore, they will certainly appreciate the professional polyurethane mastic “Blokada”, which does not require special preparation of the treated surfaces and takes a minimum of time and effort. This is fire resistant and non-flammable material does not form seams on the surface, and even a non-professional can work with it. The sealing of seams and joints carried out using “Blockade” will ensure a long service life of the room. Having penetrated into the material of the building structure, the mastic will provide it with 100% protection from moisture absorption.

Polyurethane basement waterproofing
An obligatory step in creating comfortable conditions in basement and semi-basement rooms is waterproofing the basement, especially if it is located at groundwater and subject to negative impact climatic factors. The composition of “Blockade” will prevent moisture from penetrating into the porous structure of concrete and its further freezing, leading to deformation and cracks. Timely waterproofing of concrete in the basement increases the service life of buildings.

The modern construction industry is developing very quickly. Every year it offers users new and improved materials. Sprayed liquid roofing is the latest innovation among roofing materials. Thanks to this material, you can quickly cover significant areas of the roof. It meets high tightness requirements. But before creating such a roof, you need to familiarize yourself with the features of the new material and the possibility of its use in private construction.

General characteristics

Liquid rubber for roofing is a modern building material, which is a combination of latex and bitumen. The material got its name for its special ductility.

Its scope of application is quite wide, it is by no means limited to roofing. It is used with great success in the repair of tunnels, roads, and for waterproofing various containers (for example, fountains and swimming pools). The distinctive qualities of the coating include the possibility of its use on various surfaces: metal, wood, slate, stone.

Therefore, liquid rubber can be safely used to repair roofs that are covered with different roofing materials. Bitumen can be used on pitched and flat roofs; once applied, it hardens almost instantly. In this case, hardening occurs without the release of toxic fumes, since the material the base also contains water.

Like any other roofing material, liquid rubber has its pros and cons. The undeniable advantages include:

A separate point worth highlighting is that liquid rubber can be laid without special skills. It will not require special heating from the novice master. Rubber is applied when cold.

She doesn’t have many disadvantages, in fact, only one - high price. On average, you will have to pay about a thousand for one square meter; this figure may vary depending on many factors: where the material was purchased, the manufacturer, etc. Of course, the high price is also due to the fact that liquid roofing is still a relatively new roof design option, perhaps , over time, more budget-friendly ones will be presented on the construction markets.

Types of material

Basically, liquid roofing is divided according to two parameters, more precisely, according to composition:

  1. One-component composition. He doesn't need any preparatory work, it is immediately applied directly to the work surface. The consistency is a viscous mass that comes in different colors.
  2. Two-component composition. Consists of a base and a special curing composition. Special preparation will be required before applying such material.

Also this one new material differs in the method of application to the surface. Can be applied with a roller or brush like regular paint. In this case, the material is a viscous substance that fills all microcracks. It can be applied by cold spraying, but this requires equipment. It is also laid using the self-leveling method, which is not much different from the technology of laying self-leveling floors, but requires a certain skill from the master.

All types of liquid roofing have one important advantage over other roofing materials: amazing stretchability and elasticity. Even though the layer of bitumen is very thin - about two millimeters, it does not stretch over time and does not tear under the influence of external force. Due to this, in pairs with seamless fabric a decent level of waterproofing of the material is ensured.

Application options

Before application, no special surface preparation is required; it is enough to clean the desired area from all existing contaminants. But the material has several methods of application.

Spray application

This method can be called the most desirable, since it has many advantages over other methods:

  • it is easy to apply the composition to junctions, bends, and geometric shapes of the roof;
  • significantly saves material and reduces application time.

For spraying, a special spraying device (gasoline engine) is used, which helps to quickly process large area roofing surface. And all thanks to mobility and relatively low weight (no more than seventy kilograms). In industrial construction, this method can be considered the main one, since it saves the amount of consumed composition; it is possible to process a significant amount of roof space at high speed: up to two thousand square meters per day.

Dyeing method

In private construction, it is not always possible to use special equipment. But the painting method involves the use of brushes and rollers available to everyone, which are very easy to work with.

Compared with the spraying method, a roof made of rubber applied with a roller is thicker. Of course, this significantly increases material consumption by up to three times. But a thicker and more durable coating will last a longer period without complaints and frequent repair work.

This application method is very popular among craftsmen who are accustomed to doing all repair work themselves, without resorting to the services of professionals. Typically, private houses have small roofs, so treating the entire surface yourself in a day is not particularly difficult.

Rubber is applied manually in several layers, each layer having an average thickness of four millimeters. Wait fifteen minutes between applying layers - this time is enough for the previous layer to dry. It is necessary to ensure that the coating is even; for this, a regular spatula is usually used.

Bulk method

This method is similar to the previous one, but the installation process can be done much faster. Liquid rubber is poured into the center of the roof and quickly began to be leveled with spatulas or rollers.

But here it’s more difficult to control the thickness of the layer. And the installation work will have to be done at a pace, because the solution dries quite quickly. And without proper skill it is very difficult to carry out such work.

Laying technology

It is necessary to strictly follow the sequence of actions so that the result is an ideal coating using this interesting solution:

Modern roofing material combines high quality and undeniable advantages in operation. The unpretentiousness of the material and ease of installation make it a very attractive coating for decorating roofs of any type. So it is not surprising that professional craftsmen, and beginners in construction are increasingly giving their preference to liquid rubber for roofing.

Among the new materials used in the construction of buildings various types, liquid roofing occupies a leading position.

Traditional materials, such as roofing felt, slate and tiles, remain in demand, but self-leveling roofing, in comparison with them, has significant advantages, the main of which are reliability and durability.

Types of liquid roofing

When constructing any building, be it multi-storey building V big city or bathhouse summer cottage, it is very important to choose the right roofing system.

The roof protects the building from atmospheric influences. If in roofing structure If an unreliable link appears, the building will begin to deform within a short time.

Neither reinforced concrete, nor brickwork, nor walls made of laminated veneer lumber can withstand the destructive effects of moisture.

Liquid materials have been used in roofing work for a long time. Over the past few years, self-leveling roofing has become widely used in various climatic zones.

The real possibilities of its operation made it possible to collect data on the advantages and disadvantages of liquid roofing.

When constructing a specific project, it is very important to choose a suitable roofing covering.

Today builders are offered the following types liquid materials:

  • liquid;
  • sprayed;
  • painting

Each type of liquid material is applied to the surface using a specific technology.

Self-leveling roofing is considered the easiest to work with. The required volume of roofing mass is prepared immediately before application, then simply poured onto the prepared area and leveled.

Special equipment is used to spray the roofing composition onto the surface.

This method allows you to achieve a uniform distribution of the fluid substance in the designated area.

Calculations confirmed that this technology It is preferable to use over large areas.

In this case, liquid roofing is used more economically and is applied more evenly.

The paint coating is used not only to protect the building from precipitation, but also as a decorative element.

It can be applied independently to a previously prepared surface using a brush or roller.

The types of liquid roofing used are divided into two groups according to the preparation method: single-component and multi-component.

In the first case, the roofing material is a homogeneous mass that can be applied to the surface without preheating or adding other components.

In specialized stores you can purchase formulations that are mixed before application to a specific surface.

The most widespread type is self-leveling roofing, which consists of a main component and a hardener.

It is convenient to apply it to roofs with a large number of joints and junctions.

Specifications

Liquid roofing has increased strength and elasticity. These properties are very important when arranging a roof in extreme climatic zones.

Sudden temperature changes do not affect the performance parameters of roofing systems.

In areas with increased seismic activity, due to the elasticity of the coating, the roof does not lose its integrity when the building deforms.

The installation of a mastic roof, like a polymer roof, is carried out according to a certain algorithm. An important feature of liquid materials is their environmental friendliness.

Neither the environment nor humans suffer from harmful emissions during the coating process, since they are absent.

Mastic coating

Among other protective materials, mastic roofing has optimal ratio prices and quality.

The design of a liquid roof based on mastic can have the following form:

  • reinforced;
  • unreinforced;
  • combined.

The required option is selected depending on local conditions. For roofing private garages, the non-reinforced method is most often used.

The technology for applying liquid roofing is simple and well established. The mastic is applied to the protected surface in an even layer several times.

To give additional strength to a liquid roof, reinforcement technology is used.

Polymer mesh or fiberglass is used as a reinforcing material. Mastic roofing with this device is applied in several stages.

The first step is to apply a coating of liquid mastic to the surface. Until it hardens, reinforcing material is laid on it. After which another layer of liquid mastic is poured.

The combined type of liquid roofing contains rolled material. The laying method is exactly the same as for reinforcement, only roofing felt is used instead of mesh.

Coating made of polymer materials

Long-term practice has convincingly proven that polymer roofing can serve for a long period of time, without requiring regular maintenance.

Today, the market offers roll and liquid materials based on polymers.

Among the advantages of polymer roofing, the following qualities can be noted:

  • fast polymerization;
  • roofing work can be carried out at sub-zero temperatures;
  • resistance to high temperatures and self-extinguishing ability.

When there is a need to cover a significant area in a short period of time, it is more practical to use a liquid coating.

It is important to note that improvement work performance characteristics liquid roofing is ongoing.

A clear confirmation of this is the polymer roofing based on polyurethane. In some advertising messages, polymer roofing is called liquid rubber.

This definition is not precise. Rubber is produced on the basis of rubber, and here synthetic substances are used, obtained as a result of complex chemical reactions.

We can agree that the polymer coating is very similar to rubber in appearance and technical characteristics. In this case, it would be more correct to call this material a polymer membrane.

Application technology

When preparing for the process of applying liquid coating, it is necessary to follow a certain sequence of actions.

The first rule, which is followed without any reservations, is that work can only be carried out during the warm period of the year, preferably in the summer.

The temperature ranges indicated in the instructions for use of liquid materials should be taken with caution.

It is important that the weather is sunny and calm. The next step is to calculate the volume of material required to cover the entire planned area.

Self-leveling roofing must have a thickness of at least 2 mm.

The packaging provides information on preparing the liquid solution for roofing. According to data obtained from practice, 1 kg of polymer substance is enough to cover 4 square meters of area.

When the work is done with your own hands, it is necessary to include an overrun of 10-15% in the calculations. This approach always pays off.

It is better that the layer of liquid roofing is thicker than planned than not having enough of it. If there is a shortage of material, you will have to interrupt work and go to the store for additional packaging.

If cavities and cracks are found on the surface, they must be puttied. The easiest way is to use sand-cement mortar for this purpose.

Then you need to prepare all the tools and liquid material for coating. Now you can get to work.

Liquid roofing is applied to the prepared surface manually or mechanically.

Each specific case determines its own method of applying the liquid mixture. If you cover your garage yourself, you can do without special equipment.

When work is carried out over large areas, it is impossible to do without small-scale mechanization.

It should be noted that the technology for laying liquid coating is simple. The most critical stage in the entire procedure is the correct choice of material and time to complete the work, then the result will be guaranteed.

IN Lately There is simply a huge variety of different innovative technologies appearing on the construction market that make it possible to carry out construction and repair work with even better quality. However, a special area in which a lot of unresolved issues remain is the waterproofing of the house and, in particular, the waterproofing of the roof. After all, the main tasks of the roof include effective protection of the building from various atmospheric phenomena, such as snow, rain, hail and others.

That is why experts are in search of the most suitable materials that will be able to provide reliable protection for the home. Today, one of such materials is. This is one of the best options for waterproofing. Our polymer waterproofing has already gained popularity among both professional builders and those who do their own repair work. First of all, this is due to the fact that liquid roof waterproofing does not require any special conditions, skills or special knowledge, and therefore roof repairs with your own hands can be done without problems, even without the help of professionals.

Below you can find out about this in more detail, especially since the reviews about liquid roofing are completely positive and everyone who has used it in construction work strongly recommends it.

What is mastic (liquid roofing) for roof waterproofing from the manufacturing company “LKM USSR”?

This mastic, better known as polymer liquid rubber (not to be confused with bitumen liquid rubber), is a special waterproofing material. It is produced on the basis of a unique polymer emulsion of our development, which is completely resistant to ultraviolet radiation. This component creates those unique properties, which allow it to begin to harden immediately after application and turn into a reliable polymer membrane, which has absolutely no seams, is elastic and very durable (service life is at least 50 years, and the guarantee is 15 years!).

Nothing is impossible for this material; it easily covers various protrusions, cracks, as well as all relief details located on the roof, such as parapets, canopies, protrusions and other roofing elements.

All-weather liquid roofing can be applied to any material:

  • Metal (contains zinc, which determines its high anti-corrosion properties);
  • Roof tiles;
  • Various roll materials;
  • Cement;
  • Reinforced concrete, both monolithic and prefabricated;
  • Natural wood;
  • Slate;
  • Bitumen;
  • Concrete
  • Profiled sheeting;
  • It is especially important to repair the PVC membrane, since it leaks quite often.

And also for any other building materials known today.

For example, a photographic review of our client’s liquid roofing:

Let's give a little explanation. It was applied in a very thin layer (less than recommended, less than 1 mm) at the rate of 1.2 kg/m2, price of waterproofing flat roof amounted to 350r/m2 including work. I applied it myself, with an ordinary roller. It turned out that the local “experts” foamed the plums, followed by two weeks of downpours, naturally no one looked at the roof, after they decided to visit it, they discovered a real lake, even if you raise fish), and according to the consumer , the roof did not leak a drop. This review makes it clear that minimum investment in material and labor costs, it is indeed possible to obtain excellent roof waterproofing.

This becomes especially noticeable when comparing this type of roofing with rolled, as well as membrane materials such as PVC membranes, which require real professionals during installation, otherwise the PVC membrane simply peels off from the welded joints and the roof may simply be blown away, or expensive repairs will be required.

Based on this, it becomes clear why liquid roofing is used not only to protect the roofs of houses that are currently being built, but also for houses and buildings that have undergone reconstruction and various restoration work. It is important that experts recommend paying attention to the fact that with the help of these innovative materials you can short terms get reliable waterproofing on a variety of surfaces.

Let's consider the pros and cons, types of roofing coverings based on the situation:

Which roof is better? Types of roofing according to materials and their classification.

PVC membrane(membrane roofing)

  • Pros: resistance to tension and compression, strength, frost resistance, durability
  • Disadvantages: welded or glued joints fall apart, requires expensive repairs, if installation is incorrect in 90% of cases, the roof “walks” and can simply be carried away, high cost, cracks

TechnoNikol and other rolled bitumen materials

  • Pros: relatively low cost, good sound insulation
  • Cons: low resistance to mechanical damage, deteriorates from ultraviolet radiation, harmful, fire hazard, poor resistance to temperature changes, does not last long (in some cases less than a year)

Bituminous shingles(soft roof)

  • Pros: beautiful, more durable, sound insulation, eliminates avalanches
  • Cons: various inaccuracies in installation often lead to cracks and ruptures
  • Poor waterproofing
  • Low resistance to temperature changes

Leafy(slate, ondulin, corrugated sheets, metal tiles and the like)

  • Pros: ease of installation, low cost, availability
  • Cons: poor sound insulation, low resistance to damage, corrosion, fragility, leaks at joints and fasteners (by the way, our roofing perfectly eliminates all these shortcomings)

Roof tiles(natural clay, polymer-sand, composite tiles)

  • Excellent decorative qualities, quite durable, environmentally friendly, fireproof, excellent thermoregulation, waterproof
  • Disadvantages: very heavy weight, high cost, complexity and duration of installation, tendency to bloom, cracking.

Polyurea

  • Pros: very durable, low adhesion to most substrates, fast application and polymerization speed, no joints, excellent waterproofing properties, self-extinguishing, resistance to petroleum products.
  • Disadvantages: very high cost, lack of truly qualified specialists for installation, color change, limited chemical resistance, the need for careful surface preparation before application, insufficient UV resistance for the price.

Liquid rubber

  • Pros: very elastic, inexpensive, fast application speed, good adhesion, good waterproofing
  • Disadvantages: extremely low resistance to ultraviolet radiation, often due to low-quality material (and everyone makes it, saving considerably on the quality of raw materials), leaks, swelling, and delamination occur. Short service life. Requires additional protection from ultraviolet radiation (for fans of liquid rubber, we offer our highly durable rubber paint or liquid roofing)).

Polyurethane waterproofing

  • Pros: good elasticity, good adhesion with proper preparation, strength
  • Disadvantages: not resistant to ultraviolet radiation (as calls from clients have shown), it actually lasts no more than 5 years on the roof, then it starts to leak, good preparation is needed, otherwise peeling is possible, applied only to a dry surface, quite toxic, since the main component in production polyurethane, poison isocyanate, if its professional use is underground structures (foundations, tunnels, etc.)

Advantages of liquid roofing LKM USSR:

In fact, such a building material is one of the best waterproofing options available on the market today and, that is why the list of its advantages and features is quite large. But the most important and significant among them should be noted:

  • Strong adhesion index (DIN ISO 2409) - G0
  • Moreover, this parameter is practically independent of the material being coated. Liquid roofing combines perfectly with bitumen (which it simply eats into, forming a single monolith), metal, concrete, wood, PVC membrane. Clients apply it directly to OSB roofs. Example of work in the photo:

  • 100% level of resistance to the negative effects of various factors, such as ultraviolet radiation, ozone, which none of the above types of roofing materials will provide.
  • Long service life. Subject to all manufacturer's recommendations and correct application liquid waterproofing material can last for several decades without losing its original appearance and properties. 15 year warranty.
  • The ability to choose the most optimal and suitable application method for you.
  • Relatively low price for our liquid roofing.
  • A fairly simple liquid roof repair. If necessary, you can quickly and easily restore the roof without spending a lot of effort and money.
  • A universal material that does not harm human health or the environment.
  • Makes it possible to create a wear-resistant, non-slip floor covering that is extremely strong and durable.
  • It is these parameters that make it possible to use it for both external and internal work.
  • Resistant to sudden temperature changes from -55...to +300 Celsius.
  • A serviceable roof; if desired, real armor can be made from our material; this is achieved by using a reinforcing layer of the cheapest geotextile (costs approximately 7 rubles per meter). It then cannot be torn or damaged, but in principle this is not necessary, since the liquid roof is all-weather and is itself extremely durable.
  • Self-application, which makes it possible to significantly save on installation and specialists, roof repairs on your own.
  • Application temperature range from -35..to +40 Celsius, even on wet surfaces, and in emergency cases, repair under water (hydraulic seal)
  • No protective coating or painting required
  • Apply without primer, without special preparation
  • Water-displacing roofing mastic
  • Dries quickly, less than 1 hour
  • Just crazy adhesion to virtually all substrates, including plastic
  • Not poisonous
  • Available in transparent version
  • It’s generally an ideal option for a pool, as it’s resistant to chemicals.

It is also necessary to note the fact that liquid roofing is quite elastic (400%), which means that it can be increased in size and returned to its original position. This waterproofing system has absolutely no joints, and therefore represents a single waterproof monolithic sheet.

How to apply liquid roofing correctly?

In order for the liquid roof to serve as long as possible and not lose its appearance and original properties, special attention should be paid to the technology of its application.

As mentioned above, this material can be applied in three ways: cold spraying, pouring method and painting. However, regardless of the method you prefer, it will be necessary to carry out preliminary work. They can be divided into several stages, namely:

  1. Remove dirt and loose coatings that are present on the old roof or other treated surface.
  2. Clean the roofs from roofing material that has peeled off.
  3. Clean the surface from oil stains and dust.

If a flat roof is used as the surface to be treated, it should be checked for the presence of stagnant zones. You should also seal those places where the parapet meets the roof or pipes, ventilation, as well as any other elements that protrude beyond the treatment area.

The main thing when creating a liquid roof is to remember that everything should be done according to the manufacturer’s recommendations and, of course, existing building codes and requirements.

What should you consider when applying liquid roofing?

No matter how simple this application procedure may be, however, as in any other matter, there are some nuances here, as well as features that must be taken into account in order to ultimately obtain good result. So, before you start applying mastic, you need to prepare all the necessary equipment. It can be an airless compressor like GRACO, nozzle 23, as well as a roller or brush. This kind of equipment will significantly facilitate the procedure for applying liquid roofing and will make it possible to carry out this procedure much faster.

It is important to note that this work can be carried out at any time of the year. The lowest temperature at which you can work is -35 degrees (but it will take 3 hours to dry).

Liquid roofing should be applied in strips, and their width should not exceed 1.5 meters, in which case you will be able to apply the waterproofing material as evenly as possible. Particular attention should be paid to the thickness of the application; it should not be too thick. Taking into account all these nuances in the work, you will get an excellent result that will protect your roof for decades!

We give a 100% guarantee that your roof, when using our material, will never leak and will last for decades. Minimum costs - maximum results! New life to old quality!

The main task of roofing coatings is to protect roofs from precipitation in the form of snow, rain, hail and other weather phenomena. Liquid roofing is considered one of the most common and effective materials, providing reliable protection from the elements.

What is liquid roofing (liquid rubber)?

Liquid roof ( waterproofing mastic) is a new generation coating waterproofing material, which is produced on the basis of latex and bitumen emulsion. When applied, liquid roofing begins to harden almost instantly, transforming into a seamless and elastic membrane.

There are no restrictions on the size or configuration of the roof for the material: the larger the area being processed, the easier and faster the roofing work. Liquid rubber easily covers even complex, relief parts of the roof: parapets, pipes, ledges and canopies.

The material is intended for application to the following types of roofing surfaces:

  • Prefabricated and monolithic reinforced concrete.
  • Slate.
  • Metal.
  • Natural wood.
  • Cement strainer.
  • Roof tiles.
  • Roll materials.

Thanks to the cold application technology, liquid roofing is considered more practical and versatile in use than roll and membrane coatings. Liquid rubber is used not only to protect roofs during the construction of new buildings, but also to protect buildings during reconstruction or repair work.

Types of roofing mastics, general characteristics of liquid roofing

The building materials market offers a wide range of roofing mastics. Based on their composition, they can be classified into two main types:

  • Multi-component.
  • One-piece.

Multi-component mastics include several components; if the mastic consists of only two elements, then it is considered two-component. The composition of each multi-component mastic must include a curing catalyst and a base component. The group of one-component mastics includes materials specially combined in the proportion required for hardening and application.

Liquid rubber belongs to the group of two-component mastics, but the term itself does not convey the essence of the material, as it is erroneous. Liquid roofing only superficially resembles rubber (in color, consistency and water resistance), the base of this material It is not rubber, but bitumen. Therefore, many foreign manufacturers of liquid rubber are in favor of renaming the material into a coating for sprayed seamless waterproofing.

Properties of liquid roofing

The basis of liquid rubber is a bitumen-polymer water emulsion, which allows minimizing the evaporation of toxic substances during application of the material. Liquid roofing is absolutely safe for environment and people, with its help you can put an object into operation in the shortest possible time, since the material is quick and easy to apply.

Liquid roofing is characterized by low fluidity, so it can be used to treat not only horizontal and flat roof surfaces, but also vertical surfaces. The material retains its protective properties even when high temperature, does not deteriorate under the influence of ultraviolet irradiation and moisture.

Depending on the bitumen and polymer additives used in the manufacturing process, as well as the specific manufacturer, the lowest temperature bending temperatures on the timber can be up to twenty degrees. Special varieties of material are also produced, designed for roofing in particularly cold areas of the country (with temperatures down to minus sixty degrees).

Over the years, bitumen ages and its appearance changes, since it contains evaporated essential oils. However, such negative consequences can be avoided by purchasing mastics containing polymer to create a special film that effectively prevents bitumen from aging. Polymer material extends the service life of liquid rubber to twenty years or more.

Another property of the material is increased elasticity and strength, which prevent the liquid roof from peeling even with sudden temperature changes, changes in humidity levels, pressure and intense vibration. The use of liquid rubber is cost-effective and effective, as it allows homeowners to avoid further maintenance of the treated roof. If necessary, liquid roofing can always be repaired or restored.

The material is also resistant to various types impacts of a mechanical nature, fireproof, resistant to the influence of most aggressive chemical solutions that are used in the construction process. If desired, liquid rubber can be combined with water-based paints, which will allow you to give the roof any color.

Types of liquid roofing

There are three main types of material:

  • Bulk: formed and prepared directly at the site of waterproofing work.
  • Sprayed: applied by cold spraying using special equipment, it is considered the classic and most common type of liquid roofing due to its ease of application and high quality created coverage.
  • Painting: waterproofing is carried out by manually applying paste and liquid film-forming materials with a brush, spatula or brush.

Liquid roofing process

Liquid roofing can be applied using cold spraying, painting or pouring technology. Regardless of the chosen work technique, it is necessary to clean and prepare the base:

  • Eliminate slate chips and other granular coatings from old roofing.
  • Remove loose roofing felt.
  • Take out the trash and remove dirt.
  • Remove dust from the surface being treated.

The base of a flat roof is first checked for the presence of stagnant zones and, if necessary, the slope is corrected (especially in places where rain or melt water drains). It is also necessary to seal the junctions of the roof with parapets, ventilation ducts, pipes and other structures protruding beyond the treated area. If the material is applied on top of old roofing felt, then it is necessary to install deflectors that are designed to eliminate moisture from the roofing pie. If necessary, the waterproofing layer is reinforced with geotextiles.

Loading technology

The base is impregnated with bitumen emulsion, maintaining the thickness of the primer layer within one to two millimeters. Then the pre-prepared liquid roofing is poured into portions onto the treated surface, distributed evenly using a special roller and leveled to two to three millimeters in thickness.

Latex-bitumen mastic begins to harden within a few seconds, but it is necessary to keep the poured layer for at least five minutes. After which you can begin applying the second layer (finishing).

Using self-leveling technology, you can level the treated roof as much as possible, but it is not suitable for pitched roofs.

Dyeing technology

For the first layer, prepare a solution consisting of water (no more than 30%) and rubber, which is evenly distributed over the base using a roller or brush. The time required for the first layer to dry completely depends on the ambient temperature. So, at a temperature of +5 you will need to wait at least two to three hours, and at +20 degrees - one hour. After this, the finishing layer is applied, and there is no longer any need to dilute the liquid rubber with water.

The material is applied to the surface with a spatula or a wide brush in a layer of two to three millimeters, after which you will need to wait at least 48 hours until the material dries completely. It is recommended to apply the second layer perpendicular to the direction of application of the first layer in order to evenly treat the roof with the material.

Dyeing technology suitable for processing pitched roofs and small-area roofs, when the use mechanical devices not economically justified.

Sputtering technology

The essence of this technique is that liquid rubber is sprayed onto the treated area using a special airless apparatus connected to two containers at once: one containing a bitumen-polymer emulsion, and the other containing calcium chloride as a hardener. Both components simultaneously enter the nozzle, where they are mixed and then applied. As a result, a polymer-bitumen membrane for waterproofing, two to four millimeters thick, appears on the treated roof. The liquid rubber applicator can be powered by either an electric or a gasoline drive.

Spraying technology is suitable for treating sloping roofs and large roof areas.

Advantages of liquid roofing

The material has the following important advantages:

  • Long service life.
  • Resistance to the negative effects of ultraviolet radiation and aggressive chemicals.
  • Possibility of storing material in a liquid state in barrels.
  • When carrying out repair work, liquid roofing can be applied to the old coating.
  • Cold spray technology allows the use of liquid rubber on roofs of any area and geometric shape.
  • Liquid roofing has high adhesion to most building materials.
  • Cost-effective: processing one square meter will require from one to three kilograms of liquid roofing.
  • After treating the surface with liquid rubber, even the most complex roofs have no seams.
  • When carrying out waterproofing work, there is no need to use electricity, fire or water.
  • Absolute safety for the environment and humans.
  • Liquid roofing provides a high degree of elasticity and strength of waterproofing.
  • The substance is not subject to corrosion and aging.
  • After treating the roof, all holes, cracks and holes that can allow moisture to pass through are eliminated, so the roof becomes completely waterproof.
  • The coating created using liquid roofing is resistant to high and low temperatures and sudden temperature changes.

Flaws

The disadvantages of the material include:

  • Increased sensitivity of liquid roofing to oil-containing solvents and substances, the effects of which must be completely eliminated.
  • Possibility of removing the coating only mechanically.
  • High cost of material.

Liquid roofing is a universal and practical material, which is perfect for processing any roof shape, configuration and characteristics.
