How to cut a wooden ceiling plinth. How to cut ceiling plinth: internal and external corners, fitting uneven corners and joining rounded corners

- This is the design of the corner. You need to join the planks in such places very carefully, otherwise appearance the decor will be hopelessly damaged. Of course, you can use quite aesthetic special corner elements.

However, naturally joined planks usually look more harmonious. And in this case you won’t have to spend money on additional parts. Therefore, later in the article we will look at how to cut the corner of the ceiling plinth correctly and how to process the seam.

Cutting ceiling plinth

Ceiling plinths are made from the most different materials– polystyrene foam, polyurethane foam, plastic, wood. To trim them, tools available in every home can be used. Expanded polystyrene strips are cut with scissors or a knife. The wooden plinth is cut with a hacksaw. How to cut a plastic skirting board is also not a question. You can cut it with a regular hacksaw.

Trimming wooden plinths is done with a regular hacksaw.

What is a miter box?

For accurate and most precise cutting of ceiling plinths, a special tool is usually used - a miter box. It is a tray made of three boards. There are slots in its walls located at a certain angle to the axis (45, 60 and 90 degrees, etc.). They are designed to guide the hacksaw blade when cutting. You can purchase a miter box for the ceiling plinth at a hardware store.

Trimming the planks at an angle of 45 degrees is done in a miter box

Trimming ceiling plinth in a miter box

Trimming in a miter box is performed as follows:

  1. The right strip is placed in the tray from left to right with the wrong side on the bottom (the part that will subsequently adjoin the ceiling). The part of the connection to the wall should be leaning against the side board of the tray (closest to you);
  2. The bar is pressed tightly against the tool and cut through the slot.

How to make a corner of a ceiling plinth

Important: When trimming, you should remember that when creating an internal corner, the edge of the plinth adjacent to the wall should be longer than that adjacent to the ceiling. When finishing the exterior, it’s the other way around.
  1. A second ceiling strip is inserted into the tray from right to left and cut;
  2. The finished planks are placed at the corner and the joint is adjusted using a knife;

The planks are placed on the corner and adjustments are made

  1. How to join the corners of a ceiling plinth? You can do this from a stepladder directly on the wall. But this is not very convenient, so experts advise combining polyurethane and foam elements and gluing them together on the floor special glue for joints.

It is best to glue the corner before installing the plinth on the walls

How to cut baseboard:

What to do if there is no miter box?

Thus, we figured out how to file ceiling plinth(the video above may help someone understand this better) using a miter box. But what to do if this tool is not at hand? In fact, it is possible to adjust the slats evenly without using it. There are two main ways to solve this problem: marking directly on the wall and making an imitation miter box.

In the first case, the procedure is as follows:

  1. The left strip is pressed tightly against the ceiling;
  2. With a pencil, line 1 is drawn directly on the ceiling along its upper edge;

How to properly cut a ceiling plinth without a miter box. Drawing the first line

  1. Next, the right ceiling element is placed on the ceiling and line 2 is drawn;
  2. A mark is placed at the intersection of the edge of the right bar with line 1;

A second line is drawn and a mark is placed on the plinth

  1. Next, the left element is again attached to the ceiling;
  2. A mark is also placed at the intersection of its upper edge with line 2;
  3. Now on each strip you need to connect the marks with the end of the lower edge of the plinth;

Then, along the resulting line, the actual cutting of the plinth is carried out at an angle.

Without using a tray, the planks can be mounted in the corner quite neatly

In order to cut an even angle, you can also use an imitation of a miter box:

  1. On a smooth plywood sheet we draw two strictly parallel lines;
  2. We put a point on one of them and, using a protractor, connect it to the second line at an angle of exactly 45 degrees (draw to the left);
  3. At a distance of 10 centimeters to the left of the first point we place the second;
  4. We connect it with the second line at an angle of 45 degrees (draw to the right).

How to cut a corner of a ceiling plinth using an imitation miter box

The improvised miter box is ready. Now all that remains is to attach the right ceiling element (wrong side) on the right with the lower edge to the line closest to you and cut it off. The same with the left bar (only you need to apply it to the left).

Advice: You can cut polystyrene foam strips with a knife. However, sharpen it properly. Otherwise, the material at the ends will simply crumble.

How to connect planks if the corner is uneven

In city apartments, and especially in old ones, the walls are rarely even. Therefore, the angles between them are often not right at all. How to properly cut down the ceiling plinth in this case?

In fact, it is not as difficult as it might seem at first glance. You just need to measure the angle. For this you can use special tool malka or just make a template out of paper and use a protractor.

An uneven angle can be measured using a small protractor

We divide the resulting angle by two, draw the corresponding miter box on the plywood and cut off the strips. Next, you just need to connect them with glue.

How to clean up corners

We found out how to cut the corner of the ceiling plinth. Now let's see how to do finishing joints How to cover the joint in the corner? If there remains a small gap here, the seal can be done with ordinary putty to match the color of the baseboard. The joints can also be sealed with silicone sealant.

The gap between the slats in the inner corner can be filled with putty

Important: Only the inner corner can be sealed with putty or sealant. The outer one should be adjusted as carefully as possible. It will be simply impossible to remove even a small gap in the future unnoticed. Especially when the baseboard is wide.

Corner elements for ceiling plinths

Trimming ceiling strips when using corner elements (special connectors), this is also usually done in a miter box. How to file the planks in this case? Everything is very simple - the cutting is done at a right angle. If you don't have a tray, you can use a regular protractor or square. Corner elements (photo):

When using corner elements, strips are cut at right angles

How to properly trim floor plinths

Floor skirting boards can be made of PVC, polyurethane, wood or MDF. Just as in the case of ceiling plinths, they need to be cut, depending on the material, with a regular hacksaw (wooden) or a metal hacksaw (plastic).

You now know how to cut down a ceiling plinth. Next, let's see how to fit and trim the floor. How to use a miter box in this case? When trimming floor plinth The procedure is approximately the same as when making a ceiling image. For inside corner:

  1. We take the first strip and place it in the tray from right to left so that it lies in it the same way as on the floor. We lean it against the far wall of the instrument as if against a wall;

The strip is inserted into the tray and pressed tightly

  1. We trim the unnecessary piece from the left end at an angle through hole 1 (picture below);
  2. We insert the second strip from left to right in exactly the same position and cut it from the right end through hole 2.

How to cut a plinth in a corner if it is external:

  1. We insert the first strip into the tray in the same way as for the inner corner (from right to left);
  2. We cut it from the left end through hole 2;
  3. We insert the second strip from left to right and cut its right end through slot 1.

How to cut ceiling plinth for external and internal corners

Advice: The end at an angle of 45 degrees should be done not only to cut elements in the corners, but also to make joints on the wall itself. In this case, the connections will not be so noticeable.

Thus, we have looked in detail at how to cut plinths in corners. The procedure is not as complicated as it might seem at first glance. Once you start pruning in a miter box or using its imitation, you will see this for yourself.

The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This instrument represents the most ancient and the simplest tool carpenter's cutter wooden parts at an angle of 90° and 45°. There are types of such devices for professional work, with rotating mechanism, in them the cutting tool can be rotated and fixed in any position.


How to cut ceiling plinth correctly

Ceiling corners They are divided into internal and external; the method of joining them is slightly different.

If necessary, you can make a miter box with your own hands. To do this, you will need three scraps of plywood or boards of the same size. First, they are applied in the form of an inverted letter “P” and the corners are marked. Then, according to the markings, slots are cut for a hacksaw almost to the very bottom, and the boards are twisted.

Internal corner

    • We take the correct measurements.
    • We install the plinth strip in the miter box so that this position exactly coincides with the placement on the ceiling.
    • The plinth should be pressed tightly against the opposite wall of the miter box. We hold and press with our free hand.
    • Place the hacksaw at an angle of 45° in the special hole and cut off the part.

  • The adjacent part must be cut in the same way, only in mirror image, as shown in the photo.

When circumcised soft materials(PVC, polystyrene foam) use a hacksaw or a regular construction knife. Then the work will be neat and with smooth edges.

External corner

  • Measure the length of the plinth from the nearest wall to the outer corner, leave a line on the inside with a pencil, indicating the desired length. It must be taken into account that the edge (its top part) should come out a little.
  • The plinth is moved into a miter box and cut off.
  • The adjacent strip also needs to be measured with a margin and cut in a mirror image to the first part.

Let's try on the ceiling plinth: the joining of the parts should be perfectly even. If the result is not achieved and there are unevenness at the joints, you can trim the edges with a regular knife until the joint is perfect.


Checking the alignment

The video describes all the nuances well:

Method two - without additional tools

For the inner corner, you can use the simplest method for perfect joining - by marking it on the ceiling. Another example of how to cut a corner nice and even.

    1. Apply the fillet to the ceiling, pressing its smooth edge tightly into the corner.
    2. Draw a line along the long side of the baseboard on the ceiling.

    1. The same action is performed with the adjacent part on the other side.

    1. Mark the point of intersection of the lines.

The result is an even angle of 45° if you draw a line from the intersection point to the edge of the part. Note that the above marking method only works with perfectly even angles.

other methods

With a good eye and precise hand action, you can use a homemade template that resembles an imitation of a miter box. To do this, take a thin board or thick plywood and draw a layout in the form of a horizontal rectangle. Use a protractor to mark 45° on the right and left sides of the rectangle. Draw lines connecting opposite edges.


Now you can cut the ceiling plinth using this layout. The steps are simple and similar to the description above in the first option. Only the ceiling parts should not be inserted, but placed on the drawing and the hacksaw should be combined with the layout markings.


Special components for docking

When installing ceiling plinths, you can bypass the question of how to cut the corner side. In a situation where you don’t want to cut anything, if you are a woman and love beauty and not carpentry, you can go the other way. We advise you to choose a plinth for your finishing, to which in the store you will find a part that matches the design and covers the joint. This method will save time and effort.

Ceiling plinths are very often used for decorating rooms. They give the ceiling a complete look and allow you to convey a particular style in the interior. In addition, they serve to mask the joints between the walls and the ceiling, where the two join various materials. Although such elements are not always present in the premises, they make the interior more complete. In the following material we will describe in detail how to cut the corner of a ceiling plinth, since in such places the joining of individual elements often poses a problem for inexperienced builders.

If the room has simple form, then only the internal corners will need to be cut. But in rooms of a more complex configuration, with columns, partitions and niches, there will also be external corners. In order for decorative elements to look beautiful, trimming must be done correctly and carefully, otherwise the appearance of the ceiling will be ruined.

To cut the ceiling plinth in the corners as best as possible, you can use high-quality and sharp tools or other means. The type of tool that will be used to cut skirting boards depends on the type of material they are made from. Thus, ceiling plinths are made from PVC, polystyrene foam, polyurethane and wood.

Most cheap option– these are PVC skirting boards. They are soft, so it is easy to leave dents and creases on them that cannot be corrected in any way. In addition, this material has the property of attracting dust. For cutting such skirting boards will do hacksaw or sharp knife.

Another fairly cheap type of material is polystyrene foam skirting boards. They crumble easily, so to cut the corners of the ceiling plinth you should only use a sharp knife or a hacksaw. Movements should be soft, without pressure.

Cutting plinths to decorate the ceiling

Another type of ceiling plinths is made from extruded polystyrene foam. They are much denser than ordinary foam plastic products (therefore they do not crumble), they cost a little more, but they are also somewhat more difficult to cut. For work, you can use the same knife or hacksaw for metal.

The most expensive skirting boards are made from polyurethane. These are elastic, strong and moisture-resistant products that are very easy to cut construction knife. True, they cannot be used in all rooms, since polyurethane is sensitive to high temperatures– it becomes deformed, begins to crack or crack.


To work with wooden baseboards, only a hacksaw with fine teeth is suitable; you can use a metal tool.

However, many novice craftsmen are interested not so much in what, but in how to correctly cut the ceiling plinth in the corners. This process requires careful calculations and accuracy from the performer. In some cases, if the interior of the room allows, you don’t have to think about how to cut a corner on the ceiling plinth, but use ready-made corner elements. They can be purchased at construction stores. In this case, the plinth is simply cut straight and inserted into the corner element. All irregularities and flaws will be hidden.

Using a miter box to cut baseboards

In carpentry, a special device made of wood, metal or plastic is often used - a miter box. There are special slots made in it that allow you to straight cut at 90º, 45º, and in more complex devices – also at 60º. There are also professional miter boxes equipped with a rotating mechanism. In them, the cutting tool can be installed and fixed at any angle to the workpiece. Before you make a ceiling plinth in the corners, you need to understand the details.


To cut the inner corner of a ceiling plinth using a miter box, you must:

  • First, you need to attach the baseboard blank to the ceiling surface and mark the length.
  • Now the piece of plinth is placed in the miter box in the same position as it should be placed on the ceiling.
  • The plinth is pressed tightly against the back wall of the miter box.
  • Hold the workpiece with one hand so that it does not move during cutting.
  • The hacksaw is installed at an angle of 45º to the workpiece.
  • Cut the plinth, controlling the degree of pressure of the hacksaw so as not to damage the product.
  • Then they move on to cutting the counter piece of plinth. It is also applied to the far wall of the miter box.
  • The workpiece is pressed and held by hand so that it does not move.
  • The hacksaw is installed at an angle of 45º to the workpiece so that the cutting direction is opposite to the first element of the plinth.
  • Cut off the corner of the plinth.

After trimming the ceiling plinths in the corners, they proceed to joining the resulting elements. If the cutting was done accurately, they will fit tightly together.


Let's look at how to cut the outer corner of a ceiling plinth using a miter box:

  • It is best to start marking and measuring the ceiling plinth from the inner corner, and only after completing it, start cutting the outer corner. Otherwise, the plank may be short and not enough to fill the entire length of the ceiling.
  • The plinth is applied to the ceiling and its length is marked.
  • Then the workpiece is placed in a miter box and pressed against the front wall.
  • The hacksaw is placed at an angle of 45º and, holding the workpiece with your hand, the corner is sawed off.
  • Similarly, it is necessary to cut off the opposite part of the outer corner.
  • The workpiece is pressed to the front of the miter box.
  • The hacksaw is placed at an angle of 45º to the baseboard and the workpiece is sawed off.

Upon completion of the work, the pieces of plinth are joined together, checking that everything is done correctly and evenly.

Marking on the ceiling to make a corner on the plinth

Exist different ways How to correctly make a corner on a ceiling plinth. Some are easier to do, others are more difficult. One of these methods is to mark the baseboard on the ceiling. True, cutting a plinth by weight is not very convenient, but it’s accurate this method not inferior to everyone else. Before cutting the plinth for the ceiling, it is applied to the surface, while all the imperfections and unevenness of the walls, as well as the size of the corners, are immediately taken into account.


Let's take a closer look at how to correctly make corners on ceiling plinths using this technique:

  • First, the two mating plinth strips must be cut at an angle of 90º;
  • One of the blanks is pressed against the wall, and its end is pressed against the opposite wall. Then the outline of the workpiece is drawn on the ceiling.
  • On next stage take the second plank and press its end against the wall in the same way. Draw a line.
  • At the intersection of the resulting lines, a point is placed at which further trimming of the skirting boards will be carried out.
  • Then each of the planks is applied to the ceiling in turn and the cutting point is transferred to the workpiece.
  • From this point, a diagonal cutting line is drawn into the corner of the plinth.

It is worth noting that this method More often used for internal corners.

Applying a miter box template

To cut the plinth in the corner of the ceiling as evenly as possible, you can use a paper, cardboard or wooden template instead of a regular miter box. Two parallel lines are drawn on it, then the central point is found and any necessary angle is laid off from it using a protractor. Before cutting the corner of the ceiling plinth without a miter box, it is worth double-checking the size of the internal or external angles between the walls of the room, using the same protractor.


The principle of cutting corners using a template is similar to using a standard miter box. In this case, the workpiece must be pressed against a parallel line and, setting the hacksaw at the desired angle, saw off the workpiece.

How to make a miter box yourself

Often the only way to evenly cut the corner of a ceiling plinth is to use special devices so that the tool does not move to the side during the cutting process. In this case, you can make a miter box yourself.

Option 1. A box in the shape of the letter P is made from three boards. The required corners are marked on the walls of the box and slots are cut in the appropriate places. The result is a complete device.

Option 2. Sometimes it is quite difficult to make the corners on the skirting boards on the ceiling as even as possible, especially if you have to hold the workpiece in weight. In this case, you can use homemade device. Take two boards and knock them down into a corner shape. Then lines with the required angles are drawn on a sheet of paper or cardboard and the template is applied to the corner. Then press the plinth, place the template under the cutting area and saw off the corner along the lines.


Option 3. If you are still in doubt about how to properly cut the corner of the plinth, almost any household item whose shape allows you to form a corner can help with this. This could be a chair or a table, simply placed close to the wall.

To understand how to properly cut a ceiling plinth, you should also familiarize yourself with the rule for measuring workpieces. So, to make an internal corner, the length begins to be measured directly from the beginning of the corner. But to determine the external corner, it is worth considering that it will protrude into the space of the room by the width of the product.

There is no need to rush and fix the workpieces before the mating plinths in the corner have been completed. In order not to redo the work, you must first make sure that the joining surfaces fit tightly to each other and to the ceiling. Small defects can be corrected with a file, thin nail file or knife, depending on the material of the product.

If cutting the skirting boards in the corners did not work out perfectly, small cracks can simply be filled with putty. In general, the process of cutting skirting boards at the corners is not at all difficult. However, for practice, you can take several small pieces of baseboard and practice on them.


Ceiling plinth - how to properly cut the corners of the ceiling plinth

At first glance, installing a ceiling plinth may not seem like such a difficult task to us. But, alas, this is far from the case. In fact, during repairs, problems of various kinds may arise that can completely rid you of the desire to do the repairs yourself. Joining ceiling plinths in the corners can be one of these difficulties. Many apartment owners who decided to carry out renovations puzzled over how to install the ceiling plinth. However, it is completely unacceptable to simply cut it at an angle of 45°. And only masters of their craft can help out with practical recommendations in solving this problem.

How to properly cut skirting boards and make corners and joints in the corners?

Incredibly scrupulous and very significant feature The specifics of installation lie in how to precisely trim and arrange it in all available corners. In fact, if you compare the baguette with an ordinary baseboard, it is equipped with respect to the base at an angle of 38-45 degrees. The generally accepted 45-degree angle cut at joint areas is sometimes very difficult to implement. When connecting ready-made edges with inside As a rule, gaps are likely.

Excellent results when cutting plinths are possible if the cut is made not only along the outer edge, but also from the outer side (optionally, if the work is carried out on the outer corner, an inner cut is added). Information on how to cut the corners of a ceiling plinth can be found in more detail using the video. The master carried out the cutting using a special miter saw. If you don’t have it at your disposal, then a home tool is also quite suitable for such a process. After the cut is organized, the texture of the cornice should be clearly visible on the back or front part.

How to properly cut a ceiling plinth with your own hands without the help of professionals?

Foam components would be more preferable for installation. They are a little easier to work with. First of all, you need to organize work on measuring inter-wall angles. If their value is close to 90°, then cutting the edges at an angle of 45° is required. This action must be done with the next trim. If the inter-wall joints are represented by any irregularities, then the radius of the corner is divided in half. Try not to confuse the parts: the baguette, the one that is fixed on the left side, should be equipped with a right cut, and the right fillet with a left one.

To make an internal corner, you must try to make sure that its lower section rises above the upper, and for an external corner - the opposite. The plastic and rather soft structure of polystyrene foam fillets eliminates the need to adjust them to each other, which can hardly be said about components made of wood or plastic. After working on the side sections, you need to estimate the plank to the ceiling for fitting. If necessary, cuts are made in the area where the base and accessory join. The work of rough joining the skirting boards is completed by fixing them with glue or screwing the fillets to the walls with further sealing of the seams.

How to properly cut corners of skirting boards, what tool to use for cutting and trimming corners?

To cut the corners of the ceiling plinth, it is recommended to work with a specialized tool. For installation of joints on professional level can come to the rescue Miter saw electric or miter box. With this toolkit, high cutting accuracy will be ensured. You don't need any special effort for this. You just need to set the required parameters and start working with the saw blade. Among the least expensive methods, it is worth noting the choice of a hacksaw or a hand miter box. Simple has a low price. But getting along with her is quite easy. The instrument is very crude. This is perhaps the only drawback. If used carelessly, the material can be damaged. Therefore, it is not worth saving on it. Having purchased material from low-grade wood or plastic, there is a risk of delamination into fibers. If you are using polystyrene foam, a saw is not required. A construction knife is quite suitable for this. Its blade must be impeccably sharpened. This will guarantee a high-precision cut and prevent delamination.

If you still haven’t managed to choose a cutting tool, then this is not a problem at all. You can safely go to the store and purchase fillets already prepared for joining. There is a different operating principle here. For frontal attachment of parts, it is recommended to make straight cuts rather than oblique ones. But their cost will be higher when compared with traditional accessories.

If you are going to cut the corners of the plinth in the room, then you need to start the work by purchasing a miter box. This makes it possible to select the required angle for working with a mounting knife or spatula, the dimensions of which will depend on the scope of the work being performed. To install a plastic structure, working with a miter box with low inclinations of up to 90° is quite suitable. Most likely, the most difficult stage is joining all the involved elements in such a way as to prevent the appearance of cracks. This time you will have to develop a sketch. The plinth is placed directly on the wall itself. If your tool kit does not contain a miter box, this moment, then the use of a stencil is quite applicable.

How to make a corner on a ceiling plinth?

To make a ceiling angle on a ceiling plinth, you will need two important components: glue and a ruler for measuring angles. At flat wall measurements are taken without any difficulty. But if there are gaps, additional measures will be required. It is advisable to treat the corners with sealant in advance. In some cases, painting is desirable. Remember that the first thing you should do is decide what the corner of the product will be, and then do the rest of the manipulations, for example, cutting out the corner.

How to cut ceiling plinths in corners?

To cope with the task you need to know about certain nuances and prepare the appropriate tool. First of all, a mark is made on the length of the ceiling at which the baseboards are planned to be laid. The length at which the corner will be mounted and the cut will be made is measured using a miter box. Then sketches are prepared with length measurements. Cutting is done with a mounting knife. Miter boxes are now sold in almost all relevant stores.

How to cut ceiling plinth?

If you are planning repairs not at a professional level, then the most familiar tool will do. The radius of the corners should vary from 45 to 90 degrees. To eliminate common errors when cutting plinths, it will be important to develop a layout. This is quite acceptable when working with a plastic product. Its cutting is carried out using the edge of the miter box. If uneven edges are noticed, then cut with a mounting knife. In plastic skirting boards, it is better to be on the safe side by measuring several parts of the stucco molding, and only after that do their separation.

What are corners for ceiling plinths?

The corners of the ceiling plinth are also called baguettes. These products are pieces of plastic. They are characterized by a decorative component. Sometimes in everyday life it is possible to see such a name as ceiling cornices. Previously, their use was limited only to the decoration of public premises. Nowadays, cornices are used everywhere, including when decorating apartments. Also, measurements of the length of the ceiling are initially taken. Often, the production of ceilings comes down to the use of polystyrene, since its structure is quite compacted. Installing baguettes requires special concentration. Installation is probably no different from ceiling finishing. Now the market building materials rich in skirting boards of various styles and textures. The aesthetic component of the corner is decorative, and the practical component is the protection of the outer corner.

Sawing corners and filing pieces requires great care. Areas of future joints should be treated. You will need cutting tools wooden products. The docking technology is almost no different from other types of such products. The main thing is not to forget to correctly prepare the calculations of the joints. Then the docking will go flawlessly.

How to join skirting boards?

For this process You will definitely need a well-sharpened pencil and a utility knife. First of all, measure the perimeter and length of the ceiling of the room, making appropriate notes in pencil. If the surface is smooth, a simple miter box will be quite suitable. It is suitable for installing skirting boards at small angles of 90-120 degrees. To create grooves for further arrangement, cuts are made. Then the bar is placed under the miter box. If the edges are uneven, it is advisable to use a utility knife.

What is a foam baseboard?

In the building materials market, polystyrene has long ago gained high purchasing power. Its installation is simple. It has become widely used for ceilings foam baseboard. All this has now become accessible and varied. You can find such a product in any store that sells repair supplies. These products have excellent decorative qualities. As a rule, plinths are sold in separate pieces. It is fastened using a stationery knife and a miter box. Having determined the length, it’s a good idea to make notes with a pencil.

How to cut a corner for a ceiling plinth?

How to cut a corner? When editing, play first vital role knowledge on how to cut a skirting board corner. To measure the angle, you need to take a protractor and a marking pencil. This will help to calculate which side of the corner the piece should be placed on. If there are any unevennesses, this is done with a miter box at a low angle. Next, cutting out the required corners is done using a stationery knife. If you are using a plastic plinth, then an approximate diagram will be useful to avoid mistakes when connecting existing elements.

How to cut the baseboard correctly?

To have an idea of ​​how to accurately cut a plinth during installation, you will need to use a stationery knife to uneven corners, as well as a miter box used for smooth surfaces. For plastic components, a hacksaw for metal will be most suitable. It will provide easy trimming, which must be carried out with extreme caution, pressing lightly on the saw or knife, so as not to accidentally injure your hand instead of cutting a corner. The miter box is only suitable for flat surfaces. Often the product is cut at a slight angle, presumably at an interval of up to 90 degrees. An ordinary stationery knife also copes with this mission perfectly. When making cuts, you should avoid areas with cracks.

What is a miter box for ceiling plinth?

This is perhaps an essential attribute for processing ceiling plinths. It is equipped with two sides of cutting ends. Cuts miter box at all possible angles from 45 to 90 degrees.

Ceiling plinth is decorative element, giving completeness to the decoration of walls and ceilings. It is glued at the junction between the walls and the ceiling with a special glue, and the greatest difficulty is usually caused by the corners, both internal and external. How to correctly cut a corner on a ceiling plinth so that there are no cracks or dents left? This question has probably been asked by everyone who has ever tried to glue a ceiling plinth with their own hands.

Types of ceiling plinths

Ceiling plinth - otherwise called fillet - can be made of different materials: wood, plastic, polyurethane, polystyrene foam or polyvinyl chloride. In addition, they differ in width and shape of the relief - it can be simple or figured. A simple-shaped fillet can be easily joined in corners without special fittings; for a wide plinth with stucco molding, it is better to spare no expense and buy special corner elements - internal and outer corners from the same material. Wood and polyurethane plinths are cut with a metal file or a strong, sharp knife. Polystyrene and PVC skirting boards are easily cut with a regular stationery knife; thanks to the thin blade, it does not crush this fragile material.

How to cut a plinth for a right angle

Most convenient way, which virtually eliminates the appearance of inconsistencies is to use. This device is a template U-shaped with slots in the side walls made at different angles. The plinth is marked in place, noting its maximum length along the ceiling for external corners and along the walls for internal ones. The plinth is placed in a miter box, leveled and cut at an angle of 45 degrees.

If you don’t have a miter box, you can make a template from cardboard or thick paper by drawing lines on it at a 45-degree angle using a protractor. The fillet is applied parallel to the edge of the sheet to the marking lines and cut along the ruler with a sharp knife.

If on one piece of plinth you need to cut a corner on both sides at once, then it is recommended to start with a more complex one - an external or uneven corner.

What to do if the internal angle is not right

The walls in our houses are not always perfect, and the angle may be more or less than 90 degrees. In this case, the standard template will not work, and it is better to use local markings. For this you will need a hard pencil - it leaves less marks on the ceiling.

The plinth is applied alternately to each of the walls forming an angle, and a line is drawn along its edge on the ceiling. A mark is made at the intersection of the lines on the baseboards. Connect it to the bottom edge of the plinth at an angle and cut off the corner with a knife using a ruler. Skirting boards cut in this way lie flat in any corner.

It is difficult to fit a fillet with stucco in the corners without the use of special corners, but if you were unable to match the fittings to the embossed plinth, you should not despair - using the above methods you can correctly cut a corner on a ceiling plinth of any shape. It is better to join the plinth in the place with the most protruding elements of the stucco molding so that the overall pattern is not disturbed, and carefully glue the joint. In this case, the fillets will look neat and fit perfectly into the design.
