How to make good glue at home. Homemade superglue - a universal assistant for the master

It often happens that during the repair process there is not enough adhesive or adhesive with the required characteristics cannot be purchased in the store. In such situations, you can make PVA glue yourself, that is, in normal home conditions. And in order to make high-quality PVA glue, you will need a base that is available in every housewife’s kitchen.

The modern consumer can purchase several options for the adhesive base:

1. PVA stationery. The adhesive has a non-waterproof base and is not allowed to be used outside the house.
2. Household PVA glue, which is most often used for wallpapering. This type The adhesive base has increased frost resistance and retains its properties at temperatures down to minus 25 degrees.
3. The product is brand “M”, super frost-resistant. It is allowed to apply them to surfaces at temperatures down to minus 35 degrees.

Any type of adhesive base provides many advantages:

• resistance to chemical reactions;
• fast setting process;
• lack of specific odor;
• non-toxic base.

The only drawback is its low water resistance. However, thanks additional components, which manufacturers add to the base, the water resistance coefficient of PVA glue has increased significantly.

Making your own adhesive base

As mentioned earlier, if you don’t have the required amount of adhesive on hand, you can quite easily make it yourself, at home. To make high-quality PVA glue, you should prepare the following ingredients:

• distilled water (1-1.2 liters);
• photographic type gelatin (approximately 5-6 g);
• regular glycerin sold in pharmacies (4-5 g);
• wheat base flour (100-120 g);
• ethyl alcohol (20-25 ml).

It is quite easy to buy any ingredient, except photographic gelatin, by visiting a nearby store or pharmacy kiosk. A the right type gelatin should be purchased in advance at a specialty store.

To make high-quality PVA glue at home, you need to follow the recommendations of experts, which you can read on the website at a time convenient for you. Step-by-step instruction preparing the adhesive base at home under normal conditions will be something like this:

• pre-purchased gelatin must be soaked in ordinary water approximately for a day;
• after the allotted time, you need to dissolve the gelatin base in a water bath;
• all the ingredients included in the PVA glue base are added to the dissolved component, except for regular glycerin and ethyl alcohol;
• All ingredients are boiled until the mass acquires the thickness of sour cream, while the mixture must be constantly stirred so that the components do not stick to the bottom of the container;
• Having obtained the desired consistency, the mass is removed from the water bath, cooled slightly, and alcohol and glycerin are added to the substance. All ingredients are thoroughly mixed again, eliminating any lumps that may appear when adding additional components.

At this stage, the PVA glue will be ready; you can use the adhesive in normal home conditions after the mass has completely cooled. It is difficult to refute the obvious fact, which indicates that anyone can make high-quality PVA glue from simple and accessible ingredients.

Recommendations regarding the use of adhesive

To use a base for gluing, it is important not only to make high-quality glue at home, but also to properly prepare the surface to be treated. Experts recommend doing the following before gluing:

• Thoroughly remove any type of dirt and dust from the surface;
• if the surface has a porous base, it must be treated with primer;
• existing old paint must be eliminated, the surface must be degreased with a special compound;
• Before application, the adhesive should be thoroughly mixed in the container and applied to required element a small amount of glue;
• All elements that need to be glued together should be pressed tightly together or a special weight should be placed on them.

Self-prepared PVA glue can be stored for six months. If the substance is not completely used, it is recommended to store the remainder at a temperature of 10-15 degrees with a “plus” sign. If the adhesive is stored at sub-zero temperatures, it can be used for one month. If you encounter any difficulties when making polyvinyl acetate, you can always go to the website and watch the instructional video. The training lesson will be taught by experienced specialists who have made the gluing mixture themselves more than once. The information received will help everyone, without exception, easily make high-quality PVA glue at home under normal conditions.

How to make real PVA glue yourself?

PVA is an adhesive widely used in various areas, and, without exaggeration, is one of the most popular.

And although you can purchase this product without any problems, making it yourself will also not be difficult, which will help out in a situation where you urgently need to glue something together, but the means are not at hand.

Is it possible to make PVA glue at home?

Polyvinyl acetate, better known as PVA glue, is produced in industrial scale on special equipment. The polyvinyl acetate dispersion and filler are mixed in the mortar mixer.

There are different types of this glue (stationery, wallpaper, universal, etc.) and, accordingly, manufacturing recipes. It is difficult to accurately follow the PVA recipe at home, but it is not at all difficult to make an analogue that will be practically inferior in its properties and characteristics.

How can you make PVA glue “with your own hands”?

There are many recipes self-cooking glue. We offer one of the most easily implemented and available recipes, almost all of the ingredients of which are sold at the pharmacy (except for photographic gelatin, which you need to look for in a specialized store, as well as flour - if you suddenly don’t have it at home, you will definitely find it in the nearest grocery store).

So, to prepare PVA you need to take:

• 1-1.2 liters of distilled water;
• 20-25 ml of ethyl alcohol;
• 4-5 g glycerin;
• 5-6 g photographic gelatin;
• 100-120 g flour.

Gelatin is soaked for a day in regular tap water. warm water according to the instructions, after which it dissolves in a steam bath. Flour and distilled water are added, and the mixture is kept on fire until it acquires the thickness of sour cream. During boiling, the mixture must be stirred constantly.

When the required consistency is achieved, the mixture is removed from the heat and cooled slightly. After this, you need to add alcohol and glycerin and stir everything thoroughly so that there are no lumps. If the formation of lumps still could not be prevented (they may appear during the boiling stage), then you can pass the glue through a sieve.

When the mass has completely cooled, it can be used for gluing paper, wood and other parts for which PVA is usually used.

You can store a homemade product for no more than six months. Ideal storage temperature is + 10-15 degrees.

Nothing bad will happen if the glue stays on room temperature, but when the thermometer is minus, the “functionality” of the product decreases sharply. It will be usable for no more than one month.

YouTube video about glue production

In this video you can clearly see how to easily make PVA at home. A very simple recipe that will make it easy to make glue even for those who are trying homemade glue production for the first time.

Manufacturers of PVA glue in Russia

In Russia, many companies produce PVA glue and dispersions. For most of them, this product is only part of the range. These enterprises specialize mainly in the production of paint and varnish products. In addition, there are companies that produce exclusively PVA products, such as Polymer Export, Rikol and others. This large manufacturers, engaged exclusively in the production of PVA glue and dispersions based on vinyl acetate.

When choosing a product, give preference reliable manufacturers, especially if you are going to glue large or expensive items.

PVA glue is used in a wide variety of areas, from gluing paper to various types of industry. This product is widely used in repair work ah (wallpapering, primer, adding to cladding solutions, gluing elements made of wood, fiberboard, etc.)

This adhesive is used in the printing and packaging industries for gluing paper products. It is also widely used in the woodworking and furniture industries, since PVA does not change the color of the wood and allows it to preserve its properties.

In the textile industry, it is used to “strengthen” carpets and join fabrics together. It is also used in the production of glass and paint and varnish products, household chemicals, shoes, etc.

Do you make glue yourself or is it better to buy it?

Prices for PVA glue vary depending on the type of glue, manufacturer, product weight, etc. For example, 1 kg of universal PVA glue costs, on average, from 40 to 60 rubles, a five to ten kilogram container will cost slightly less.

In general, this product has a very reasonable price, and if any complex or important work is expected, then it is better to buy glue made in an industrial environment. But if you already have experience self-made PVA, or there is no way to purchase it, but something needs to be glued urgently, then you can do it without any problems on your own.

What can replace PVA glue?

The problem with replacing PVA most often occurs among those who live in foreign countries, since this product is sometimes quite difficult to find there. If suddenly there is a need to find a replacement, then you need to focus on the material of the surfaces that must be connected. For wooden parts you can buy special glue for wood, for gluing wallpaper - “wallpaper”, etc. Paper or cardboard is glued at home using ordinary paste (made from flour and/or potato starch. So it’s not difficult to find a substitute for PVA, the only negative that such products often cost more than this universal, inexpensive and popular glue.

How to make PVA glue at home

Making PVA glue yourself without leaving home is the topic of today’s article.

Without exaggerating, we can say about PVA glue that it one of the best and most popular adhesive materials. This glue is used for gluing paper, wallpaper, and some other surfaces.

I would like to immediately note that preparing such glue yourself is not a difficult task.

If a situation arises in which you urgently need to glue something together and there is no time or opportunity to go to the store, then you should not be upset, you can prepare PVA yourself. If you follow all the rules and tips, the prepared glue will turn out no worse than the purchased one, and you will be able to save money.

Polyvinyl acetate information

What is polyvinyl acetate? This is the well-known PVA glue. If we talk about the production of glue in industrial scale, then it is made using special equipment. To make it, you need to mix polyvinyl acetate dispersion and filler. All this is mixed in a mortar mixer.

Recipe for making glue at home

There are several ways to prepare glue, but this is the simplest and most common. Besides, everything necessary ingredients Apart from photographic gelatin, it is easy to buy in every pharmacy. True, this recipe will still need flour; of course, you can’t buy it at the pharmacy, but any grocery store, as they say, will help.

What ingredients are needed to make PVA glue?

• Distilled water. You will need about a liter and a half of this water.
• Ethyl alcohol, you need about 25 ml.
• teaspoon glycerin. This is approximately 5 grams.
• the same amount of photographic gelatin.
• And, of course, flour. It will take about 100-110 grams.

1. First you need to soak the gelatin in warm plain water. for a day.
2. Then you need it dissolve using a steam bath.
3. Next, you need to add water and flour to the gelatin.
4. The resulting mixture should be kept on fire until a consistency resembling thick sour cream.
5. While the mixture is on fire, it should be stirred without interruption. After obtaining the required consistency, the mixture must be removed from the heat and allowed to cool slightly.
6. Then you need to add glycerin and alcohol, mix the resulting mixture so that there are no lumps.

Once the mixture has completely cooled, it can be used to glue the same materials for which PVA is usually used.

You can store your own prepared glue no more than six months.

Where can you use PVA glue?

Application area of this product is quite wide. It can be used to glue wallpaper, wood elements, and fiberboard.

Printing, packaging industry, woodworking, furniture industry, they all use PVA glue successfully.

To strengthen carpets and join fabrics, the textile industry also uses PVA glue. Its application also extends to glass production and paint and varnish products. Household chemicals also cannot do without the participation of this wonderful remedy.

Well, what if you need to glue it? something simple If you can’t go to the store, it’s worth practicing making glue. In this way, both PVA will work and practice will appear.

To prepare the glue, a certain amount of it is placed in a container, where water is added in a thin stream, with constant stirring, in a ratio of one to two (there should be more liquid). It turns out to be a rather thick mass. It is very important to take a responsible approach to the mixing process - the quality of the resulting product directly depends on it.

This event usually takes up to half an hour.

Using a mixer with an attachment this time can be reduced. The resulting glue perfectly connects parts of wood and leather, and is widely used for shoe repair. But the prepared mass must be used within two to three hours, then it will harden and lose its adhesive ability.

Turbo composition - liquid glue from old linoleum

In addition to those listed above, there are many various techniques preparation of high-quality glue for glass, blocks and PVC.

This composition, prepared at home, can be successfully used for pasting walls and ceiling surfaces. It is enough to choose from a variety of recipes the one that best suits you.

Very simple and affordable way– use of old, used linoleum and acetone. The process is very simple. Linoleum must be crushed (cut with a knife or scissors) into small fragments that need to be placed in an airtight container.

Then add acetone there, in an amount twice the amount of the first ingredient.

Close the container with the contents tightly and leave in a dark place for about half a day (12 hours). Usually this time is enough for the pieces flooring dissolved completely. The resulting product can reliably join products made of porcelain, metal, leather, wood, ceramics and other materials.

If you have ever carried out work where there is a need to use glue, you have probably encountered a problem, which is expressed in the low quality of the purchased composition. This is why home craftsmen often think about how to make glue. Many people today are trying to find alternative solution, which involves creating an adhesive with your own hands. If you are used to constantly making something, as well as experimenting, then recommendations on how to make glue will be extremely useful.

Making paste

In some cases, this is resorted to only when there is an urgent need to carry out any work related to the use of glue. This may relate to an incorrectly calculated volume of the composition, which ended in the midst of wallpapering work. How to make PVA glue at home will be described below, but the paste is prepared a little differently.

In order not to give up and not go to the store, you can make glue at home, and its quality will be not only similar, but in some cases even higher than store-bought analogues. At the same time, you can be sure that the composition will not contain substances harmful to human health. If you are thinking about how to make glue, then you need to prepare materials that can be found in every home. Among the ingredients you can highlight wheat flour.

To carry out the manipulations, you will need 1 liter of water, 6 tablespoons of flour, as well as a container, the last of which should be selected depending on the expected amount of glue. First you need to heat the water to 100 degrees, then dilute the mentioned volume of flour in a small amount of water in a separate bowl until it forms. If you are interested in the question of how to make homemade PVA glue, then the tips below will be useful to you. The mixture should be free of lumps. As a result, you should get a composition that resembles thick sour cream in consistency. It needs to be poured into boiling water in a thin stream, while stirring constantly. The composition is brought to a boil and left until it cools. When finished, this glue will have the consistency of jelly. If you are faced with the task of how to make glue, then you can also use starch. In terms of effectiveness, it will be the same as the mixture described above. In some cases, such adhesives are superior in quality to industrial options. The wallpaper will stick firmly to any surface. Using this composition it will be possible to glue all types of cardboard and paper.

PVA glue recipe

Before you do, you should familiarize yourself with the technology. This composition is the most common among those used when performing repair work. Among other things, large-scale construction operations cannot be done without this mixture. The composition is used even in the preparation of solutions that are used for tiling surfaces. It is applied instead of a primer, and also before final finishing. The scope of application is wide, which is why we can say with confidence that polyvinyl acetate is universal remedy, which you can prepare yourself. If you are thinking about how to make PVA glue, then it is important to consider that it must contain a strict ratio of all ingredients. Thus, per liter of distilled water you will need 20 milliliters of ethyl alcohol, 4 grams of pharmaceutical glycerin, 5 grams of photographic gelatin, and 100 grams of wheat flour. You will learn how to make glue from flour and water in the article. In order to prepare the composition, it is necessary to go through two stages, the first is the preparatory stage, during which the gelatin must be soaked in a glass for a day. The second stage is the main one.

After the gelatin has softened in water, you can begin preparing the glue. The container into which distilled water will need to be poured should be placed in a water bath. You need to add gelatin and flour to it, the latter of which is mixed in a small amount of water. The mixture should be without lumps. It is brought to a boil, but there is no need to boil. The composition should resemble thick sour cream in consistency. In order to achieve homogeneity, you should constantly stir the mixture. If you are faced with the question of how to make PVA glue at home, then you can use the recommendations given in the article. On next stage Alcohol and glycerin are added to the mixture obtained in a water bath. In order to obtain the thickest possible mass, the mixture must be thoroughly mixed. These manipulations can take up to 10 minutes, which will depend on the volume of glue. Before using the composition, it must be cooled well.

Making wood glue

This type of glue is the most suitable option for gluing wood. The composition also effectively copes with gluing cardboard, paper, and other materials. However, such mixtures have some peculiarities, among them an unpleasant pungent odor, as well as a short shelf life in liquid form, since the ingredients quickly deteriorate, gelatinize and become moldy. For these reasons, the glue must first be boiled, and then a mass of gelatinous consistency must be prepared. If necessary, you can cut pieces of the required volume, and then heat them over low heat, which will allow the mass to take on a liquid appearance. There are several ways, one of which will help you prepare high-quality glue. Below are the most affordable ones for home use.

The first method of making wood glue

If you are thinking about how to make glue at home, then you can use traditional glue. It is crushed and soaked in a container of water until the particles completely swell. The composition should become as soft as possible. The latter is placed in a melting container. You can make it yourself using a tin can. The container is placed on water bath and exposed to low heat. It is important to constantly mix the composition using a wooden stick. It is worth excluding the moment of burning, since in this case the mass will change color and lose its adhesive ability. As soon as the mass turns into a liquid state, it must be diluted with vodka using a certain proportion. It involves using 950 grams of vodka per 720 grams of adhesive. Depending on the volume of glue, you need to add powdered alum. They are used in the amount of 12 grams for every 100 grams adhesive composition.

If you can properly prepare wood glue in this way, you can ensure maximum strength of the surfaces, as well as their water-repellent properties.

The second method of preparing wood glue

If you are thinking about how to make glue at home, then you can use the second method. To do this in tin can You should boil traditional wood glue, adding water in a one to one ratio. After this, when the composition thickens somewhat, the mass should be poured into a porcelain container, and then use a stick to rub until a gelatinous mass is formed. It is laid out on a plate, then cooled well and cut into separate pieces. In this form, the composition can be sent for storage, and if the need arises to use it, then for every 720 grams of the preparation you need to add 360 grams of vodka and 720 grams of water. The resulting mixture is brought to a boil.

The third method of making wood glue

If used this technology, then you should use a water bath, add a liter of water and 1 kilogram of traditional wood glue to the container. It is important to prepare and add 1 liter of 9% table vinegar. Once the ingredients have dissolved, you can add a liter of vodka, ensuring constant stirring.

The fourth method of making wood glue

Before you do, you must choose the most optimal method of carrying out the work for you. As the latest technology, a technique will be described that involves the use of wood glue and water, these ingredients are used in a one-to-one ratio. It is important to heat the future composition in a water bath, achieving complete thickening. Then a weight portion of glycerin is added, which is equivalent to the weight portion of the glue. It is important to heat this composition until the water has completely evaporated. The resulting mixture should be placed in a mold and then dried. This glue will be stored exactly as long as necessary. To use, you will need to dilute it with water using a one to one ratio.

Making glue for foam plastic

IN Lately Foam plastic and expanded polystyrene are often used for heat and sound insulation of residential buildings. They are mounted on load-bearing wall. When choosing a composition for fixing these materials, you should take into account that solvents such as acetone can melt the canvas. That is why, as the most suitable option and wood glue comes out. However, at home you can make another waterproof composition where you should use cottage cheese. To carry out this work, you should mix this ingredient with in equal proportions until you get a homogeneous mass. It is advisable to use this composition after preparation, without leaving it for storage, as it quickly becomes hard.

Making wood glue

Information on how to make glue from starch was presented above. However, in some cases it becomes necessary to glue puzzles, wood or leather. Great option For this purpose there is a glue called casein.

First stage

At home, you should carry out the process of defatting cottage cheese. Why is it soaked in soda solution for 20 minutes. For 1 liter of water, use about 2 tablespoons of baking soda. You can then rinse thoroughly running water, the curd must be squeezed out and dried until it reaches a firm consistency. A powder called casein should be prepared from it.

Glue preparation process

You already know how to make glue from flour, now it’s time to familiarize yourself with the information that expresses the technology for producing an adhesive composition from dry casein. To do this, the powder is poured into any container, which should preferably be flat. Afterwards you need to add a little water, constantly stirring the composition. For one part powder, use two parts liquid. This will allow you to get a fairly thick mass.

Mixing will take approximately 30 minutes. However this process It is possible to speed it up using a mixer. This glue will perfectly strengthen wood elements together. The disadvantage of this mixture is that it must be used within 3 hours. After this time, the mixture will harden and will be unusable.

Preparing glue for needlewomen

If you are still interested in the question of how to make glue from flour, then you should familiarize yourself with the information presented below. If you need gluing different types fabric, then for this you can use a special glue, which is made on the basis of wheat flour.

For 3 tablespoons of flour you will need 1 glass of water. The ingredients are mixed and then poured into a glass of boiling water. This mixture should be brought to a boil; after it has cooled, you can use it.

Second way

If you are faced with the task of making homemade glue, then you can use a slightly different method; it involves using one tablespoon of flour, the same amount of potato starch, as well as granulated sugar in the mentioned volume. All ingredients are mixed together, poured into a glass of water and brought to a boil.

Industrial glue does not always satisfy the consumer, and sometimes force majeure circumstances arise when something needs to be glued, but there is nothing suitable at home. Self-prepared adhesives will help out.

PVA glue at home - an affordable recipe

When there is an urgent need to glue parts together, but there is nothing at hand, you can make glue yourself. There are many recipes that reveal the secrets of their manufacture. Most do not require any special components; all are available and commercially available. By adhering to the recipe and technology, you can be confident in the quality of the ingredients. (PVA) is one of the most popular due to its versatility and wide range of consumption. It is used to join paper, cardboard, leather, wood, fabrics, glass, and porcelain. In everyday life, it has proven itself well as wallpaper glue and a composition for furniture repair. PVA is widely used in construction as an additive to increase adhesion, gluing linoleum and tiles.

It is quite possible to make PVA at home; of course, the glue will not fully meet the industrial recipe, but the characteristics of such a home-made composition are similar to those of a store-bought one. We buy ingredients: distilled water, gelatin used in photography, glycerin, wheat flour, ethyl alcohol. If we buy glycerin and alcohol at the pharmacy, then photo gelatin can only be found in specialized photography stores. Distilled water is sold in auto stores.

First, soak 5 grams of gelatin in a small amount of water for a day so that it swells well. Immediately before preparing the PVA, stir cold water 100 grams of flour until smooth and without lumps. Heat a liter of water in a water bath, gradually pouring in a solution of gelatin and flour. Stirring constantly, bring to a boil and turn off the heat. Add 4 grams of glycerin and 20 ml of alcohol, mix everything for 5-10 minutes to obtain a thick, homogeneous mass. Cooled PVA is ready for use. Despite its versatility, the capabilities of PVA are still limited to certain materials. But there are alternatives, including homemade, which we will discuss below.

Wallpaper paste made from flour - how to prepare it correctly?

The variety of wallpaper adhesives and their recipes are amazing. Each package indicates what the glue is made from. various types wallpaper It is unlikely that you will be able to prepare this at home, but there is a recipe for flour paste - old and proven over the years.

Preparing the paste is simple and quick: you need flour or starch and water. For two or three rolls of wallpaper, one liter is enough. For this amount we take 6 tablespoons of starch or flour. We put a liter of water on the fire, and until it boils, in a small volume cold water separate the flour. Stir thoroughly so that there are not the slightest lumps. The thickness of the mixture should resemble sour cream. Slowly pour it into boiling water, stirring constantly. Let it boil again and leave to cool.

The finished composition should resemble thick jelly in consistency. The use of paste for gluing walls with wallpaper ensures that they will adhere perfectly to a wall made of any material. It is also capable of joining any kind of paper and cardboard. The advantages are undeniable: very cheap, environmentally friendly. The quality of a properly prepared paste is superior to some industrial samples.

How to join wooden materials - a simple solution

Wood glue is traditionally used for gluing wood, which is considered the best for these purposes. It has some features that do not allow it to be stored in finished form for a long time. In a liquid state, after a short time it turns into gelatin and is covered with mold. More long time A gelatinous mass can be stored, from which pieces are cut for subsequent preparation of casein glue. There are several cooking methods.

According to the first method, we grind the most common wood glue and soak it in water until it swells completely. Ready mix soft, reminiscent of jelly. We melt this mass in a water bath in a container called a glue bottle. If it is not there, we use any utensil, even a tin can. The fire should be very low, make sure that the mass does not burn. Burnt glue turns yellow and is weaker than properly prepared glue.

Constantly stir the gelatinous mass wooden stick until it becomes liquid. Add vodka to this liquid at the rate of one liter per 760 grams. You will need powdered alum - 12 grams per 100 grams of glue. This recipe allows you to prepare the most durable wood glue with water-repellent properties.

It’s easier to make wood glue using the second method. In a glass bottle, bring wood glue to a boil in the same ratio with water. When the mixture begins to cool and becomes thicker, pour it into a porcelain mortar and grind with a pestle until the mass becomes gelatinous. Place the mixture on a plate, wait until it cools, and cut into smaller pieces. If necessary, dissolve the piece in water 1:1 and vodka, with which we take half the mass of the workpiece. Boil the mixture and cool.

Another easy way. We take equal parts of wood glue, 9% vinegar and vodka. First, boil the vinegar and glue in a water bath until the mixture is completely dissolved. Stirring constantly, add vodka. According to another recipe, we heat equal parts of glue and water in a water bath until the mixture becomes thick. Add glycerin equal in mass to the glue and continue heating until the water has completely evaporated. Dry the finished mixture and, if necessary, dilute it with water in equal proportions.

The possibilities of wood glue – did you know about it?

The capabilities of wood glue are not limited to just gluing wooden products, they are much wider. Based on it, you can prepare many adhesive compositions for various purposes. We will talk about syndeticone below, but for now let’s focus on other recipes.

It turns out that you can glue wood with metal, stone, glass with it, you just need to prepare the adhesive paste. Sift wood ash through a fine sieve and add it to hot wood glue. To restore book bindings or create new ones, we also use wood glue to which we add glycerin (by weight, 1 part glycerin for 20 parts of glue). You can make waterproof glue, just add 1 part to 4 parts of hot wood glue natural drying oil.

How to isolate casein from cottage cheese and milk?

This universal product for household repair work is used not only for joining wood to wood, but also in combination with other materials: cardboard, plastic, fabric, leather. It is also capable of firmly gluing earthenware, plastic, and foam. Proper work with such glue guarantees that the connection will be strong and durable.

On sale casein is heavy White powder, and to make glue from it, you only need water. But you can isolate casein from ordinary cow’s milk at home. The method is little known, but interesting. In addition to milk, vinegar is used, which separates it into liquid and solid components. With the addition of soda, an alkaline environment is formed, which dissolves casein. You should be aware that the resulting product is not food grade.

To make casein glue, we perform simple operations with our own hands:

1. 1. In any container ( better frying pan) heat the milk, but do not bring it to a boil. Add 9 teaspoons of vinegar per liter of hot milk and heat, stirring until lumps of curd and whey form.
2. 2. Through a sieve, separate the solid part from the liquid and put it back on the frying pan. Add a little water and 3 tablespoons of soda, heat until bubbles appear on the surface.
3. 3. Mix the mass well and leave to cool. It can be used as glue.

You can also isolate casein from cottage cheese by defatting it. To do this, soak it in an alkaline solution for 20 minutes. Prepare an alkaline solution from two spoons baking soda, dissolved in water. Then rinse the cottage cheese thoroughly with running water, squeeze and dry. Once dry it will become hard. We prepare a powder from it, which is casein.

Prepare glue from dry casein powder. We measure required amount powder and twice as much water. Pour the powder into a flat-bottomed bowl, add water little by little, without stopping stirring. The quality of the desired product depends on the quality of mixing. You can use a regular mixer, the work will go faster, but by hand it will take at least half an hour. The result will be a thick mass that must be used immediately, otherwise in about two hours it will harden and become unusable.

How to create hot melt adhesive - nothing could be easier

Perhaps the best invention that allows you to stick everything to everything is hot or thermoplastic glue. It has one feature that fundamentally distinguishes it from its counterparts - it passes from solid to liquid and back without losing its qualities and without changing volume. Industrially produced as rods different colors. To use it, you will need special equipment - a heat gun.

Do hot glue at home you can use ordinary plastic bottle. To do this, we cut strips of the required length, twice as wide as the parts to be glued. We bend the strip in half along its length and place it on one of the surfaces to be glued. Will need construction hair dryer, which we use to heat the plastic. When it softens, apply another part and wait until it hardens completely. Cut off excess glue with a knife.

The advantage of homemade hot glue is that it can be reused. If gluing does not work the first time, heat up the joint and repeat the process. If the parts are connected by mistake, it’s okay: we heat up and separate the parts, remove the remaining glue. The parts glued in this way are held tightly. Industrial hot melt adhesive is disposable - only rods are used for the hot melt gun.

Homemade superglue - a universal assistant for the master

You can get glue with the characteristics of a universal one using carpentry glue. Take 400 ml of water and dissolve half a glass of sugar, mix slaked lime– 30 grams. Heat for an hour, stirring all the time. We get a clear solution, drain it and add 120 grams of wood glue, cut into pieces. We wait for the moment of complete swelling and cook as usual until a homogeneous substance is obtained.

You can make superglue using another recipe. A very affordable method that does not require large expenses is based on acetone. We use pieces of linoleum or plastic as filler. Place in small pieces in a container, which can then be tightly closed. Fill the raw material with double the amount of acetone, seal the container hermetically and place it in a dark place. We watch when everything dissolves and use it to join wood, metal, porcelain and other things.
