How to trim the outside corner of a skirting board

Which skirting board is better to choose?

There are many varieties of fillets, which differ in the following characteristics: material of manufacture, shape, and dimensions. When choosing a ceiling plinth, it is recommended to focus on all these factors, but the material of manufacture is the key point that determines the complexity of processing.

trim, corner, skirting, board

The highest quality polyurethane fillets are considered. However, they are the least suitable for cutting corners, since the material is highly elastic. The easiest way to cut the inner or outer corner of a polyurethane skirting board is to use a miter box. The main disadvantage of such products is their poor resistance to high temperatures, therefore they are prohibited from using in the kitchen.


Products made from other materials also have their drawbacks. Ceiling skirting boards made of PVC are prone to dents. In turn, polystyrene foam products break easily, so they must be handled very carefully.

So which skirting board should you choose? There is no definite answer to this question. Experts recommend focusing on the individual characteristics of the premises and the budget, calculated in advance.

How to cut a corner of a ceiling plinth

In this article, we will tell you how to properly cut the outer and inner corner of the ceiling plinth with your own hands. This can be done without using special tools, but it should be understood that such work requires care and accuracy.

Miter box cutting: inner corner

The easiest way to get the correct inside corner is to use a professional tool. Of course, such work can be done without a miter box, however, in this case, more effort will be required. Consider the sequence of actions for cutting an inner corner using a miter box.

The first thing to do is determine the distance from the outside corner to the nearest wall. Next, you need to mark the plinth, thereby preparing it for cutting. On the outside of the fillet, you need to draw a fishing line along the length of the measurement. It is worth considering that in this case, the upper part of the die should protrude slightly outward.

Then you can start trimming. For this, the skirting board is placed in the cutting tool and firmly pressed against the wall. After trimming the first part, you can start processing the counter element.

Miter box cutting: outside corner

Most often, when installing ceiling plinths, home craftsmen are interested in how to correctly arrange the interior corners in the room. Cutting outside corners is done less often, but with a certain layout of the walls, it is necessary. Consider how to correctly make an internal fillet using a special tool (miter box).

First you need to purchase a miter box. This tool is a tray in which the part is fixed and trimmed. In order to measure the length of the required product, you need to attach it to the ceiling. Next, you need to install the skirting board in the miter box. Its location should correspond to the position that it will occupy on the ceiling.

Miter box

How to properly cut the inner corner of the ceiling plinth is a difficult question, which can be answered by the corresponding photos. Experts recommend that you study them, and only then start work.

After you have made sure that the product is positioned correctly in the tool, you can start cutting itself. The hacksaw must have a certain angle, namely 45 degrees. During work, it is not recommended to apply strong pressure on the cutting tool, as the surface of the miter box can be damaged. Then the adjacent fillet is trimmed, which is done in a “mirror” way.

Cutting corners without a miter box

Not everyone has the opportunity to purchase a professional cutting tool. And the expediency of such a purchase is rarely justified, since spending money on a miter box that will be used only once is not the best solution. You can trim fillets without it. There are several alternative ways to get the right angles.

Manual template preparation

The first and most common option for trimming fillets without using a miter box takes into account the use of a paper stencil. To implement this method, you will need to prepare the following tools and materials:

  • protractor;
  • pencil;
  • cardboard.

We apply a plinth to the cardboard blank and cut it off with a hacksaw. Some craftsmen make markings on the product itself. In this case, there is no need to use the template.

The second option is to make your own cutting tool. To do this, you will need to prepare 3 boards that have the same dimensions (50 by 15 cm). Next, you need to dock them together. The two side boards, which are walls, must be fixed to the cross board at right angles. In the next step, you need to mark an angle on the walls of 45 degrees. You can take the necessary measurements using a simple square. The ready-made tool will allow you to arrange all the corners in the room in a short period of time.

The third method takes into account the use of improvised means. In this case, there is no need to construct a template. It can be replaced by a regular table, which will need to be moved to the wall. It is necessary to attach a fillet to the corner formed in this way, and then mark it. At the end, the part is cut with a hacksaw or a construction knife.

Cutting an oblique angle

Walls do not always have a perfectly flat surface. In this case, it is very difficult to carry out the installation of ceiling plinths, since few people know what exactly needs to be done in such a situation. The most preferable solution to cope with this problem is to mark the corner in place.

For marking, you need to prepare a regular pencil. Before starting work, it is recommended that you familiarize yourself with the video, which describes the nuances of cutting fillets. The first step is to attach the plinth to two walls (in turn). Along its edge it is necessary to draw a fishing line, which is marked on the ceiling. The point that corresponds to the intersection of the lines is marked with a pencil.

In the horse, it is necessary to connect the point to the lower edge of the fillet. Next, trimming is done. It is recommended to use a ruler during work. If the work was done correctly, then the resulting angle will repeat the relief of the wall.

In order to cut the correct corner of the ceiling plinth with your own hands, it is not necessary to use a professional tool. There are other methods that do not require anything complicated from the master. In such work, the most important point is the correct markup. Before you start cutting, be sure to make sure that you are doing everything correctly.

What advice can you give for cutting the corners of ceiling plinths??

What tools will be needed?

For ceiling plinths, the following tools may come in handy, depending on the chosen method of work:

  • Saw on wood. Suitable for working with wooden ceiling plinths.
  • Metal sheet. Suitable for other types of skirting boards (foam, plastic, etc.).
  • Miter box. The tool is a chute, which has the shape of an inverted P, where mowing lines are outlined at angles of 45 ° and 90 ° for cutting.
  • Electric miter saw. Can be used instead of a miter box, helps to achieve high cutting accuracy.
  • Electric jigsaw. Easy to operate, with the help of it you can efficiently and correctly cut a corner without burrs.
  • Stationery or construction knife. Suitable for foam skirting boards, it is important that it has an excellent cutting blade, and therefore must be well sharpened.

Important points on how to cut a ceiling plinth in the corners

Let’s consider how to correctly cut the corners of the ceiling plinth and get an excellent result the first time. Follow a few helpful tips:

  • Before fastening, both parts must be matched to each other. Place both halves together. The surface of the wall must be dry. Having found defects, you can easily level them with a knife.
  • Several trims may be required. Don’t be discouraged if it takes a long time and has to make a few trims, especially if this is your first time doing the job.
  • Determine the correct length of the planks in the corners. For the inner corner, the length of the plank must be adjusted exactly from corner to corner; on the outer corner, the measurement is taken from the inner point in the direction of the room.

How to join skirting boards in the corners

When a certain part of the plinth is glued and a small distance remains to the corner, so as not to be mistaken with the length, it is necessary to leave a margin. To begin with, you can cut off a piece that will be 10-15 cm longer. Then cut the corner in a convenient way, try it on a dry surface, attach the plank to the ceiling and highlight the place to which it needs to be shortened. Undercutting is performed at an angle of 90 °.

Next, you need to correctly join the corners. The made ceiling moldings are attached at an angle of 38-45 °, so the classic 45 ° is not always suitable at the joints. In various cases, the cut edges do not join and leave gaps. For this reason, after the initial trimming of the corners, it is necessary to carry out a “dry” and the most accurate joining of the baguettes directly to the ceiling. Especially have to tinker with wood and plastic materials.

Having completed the rough joining of the skirting boards, glue or screw the fillets to the walls and ceiling, then, if necessary, use a putty and seal the seams at the end.

How to glue a ceiling plinth

Start from the corners of the room, as they are easier to work with, then move on to other parts of the room. Cover the corners in such a way that, if possible, there are no gaps or defects, if they are unavoidable, are insignificant. For plastic skirting boards, use a finishing putty.

Water or soil is applied to the areas for fasteners. After the putty mixture has dried, all the cracks need to be repaired. various sealants are used for sealing (professional builders recommend choosing acrylic-based products). In general, one package is required per room. Installation with a sealant is carried out in the same way as when using a putty.

Method number 1. Classic miter box

The classic miter box is a U-shaped bed with slots in the opposite sides. A part of a suitable size is inserted into this stock and sawed off with a hacksaw through the slots in the sides. The idea is not new, the tool is already several hundred years old, but despite the simplicity, not everyone knows how to properly cut the corner of the ceiling plinth using such a miter box.

Not everyone knows how to cut a ceiling plinth in a corner using a classic miter box.

Tip: when trimming, ceiling skirting boards are applied to the side of the miter box, which is closer to you, and the floor skirting boards, on the contrary, must be applied to the side of the tool farthest from you. This is not a dogma, but it is much easier to work this way.

It is easier to work with floor skirting boards, as the miter box lies on a horizontal plane, it is easier for you to orient yourself in the position of the skirting board. People most often make mistakes when trimming the ceiling fillet, it is simply incorrectly put into the tool. There is a simple but important rule here.

Important: the side of the ceiling fillet, which touches the wall, should be directed to the upper edge of the side of the miter box, and that part of the plinth that borders on the ceiling is placed on the bottom of the miter box.

Skirting board trimming scheme.

The corner, as you know, has 2 sides, so, in order to make less mistakes, train yourself to put the bar that will be mounted on the right side of the corner into the miter box on the right, and the bar that is attached to the left, put it into the miter box on the left. Details about the intricacies of using the classic miter box are described in the video in this article.

How to properly trim the inner and outer corners of the ceiling fillet.

In addition to the classic U-shaped miter box, there are two more types of similar designs. a professional and a rotary tool. As for the professional version, only masters use it. The device is quite bulky, but it turns at any angle and has a hacksaw that can be fixed in the desired position.

The swivel device can be safely called a “” miter box. The only advantage here is the ability to clearly fix the angle of rotation of the bar. On the one hand, it is easy to work with it. set the corner, put it on the plinth and cut it off. But on the other hand, you need to get used to such a tool, if you do not have experience with a hacksaw, then you should not take a rotary miter box.

How to work with a swivel miter box.

Tip: when choosing a classic U-shaped miter box, firstly, do not take Chinese products. And secondly, try to buy models with the possibility of rigid fixation of the part inside, one of these models is shown in the photo below.

A miter box with the ability to fix a part inside is much more convenient to work.

Three working ways to trim skirting boards

For floor and ceiling skirting boards, the trimming instructions are almost the same. But if on the floor the curved corner can be covered with something, then on the ceiling this is already a problem, so we will pay more attention to how to cut the ceiling plinths.

How to cut a skirting board at any angle and without gaps. 3 working ways from a practitioner

There are more than enough tips on how to cut a plinth at 45 degrees on the net now, the only bad thing is that most of them are given by people who have never done it. Further, from the point of view of a practice, I will tell you how to cut skirting boards at the corners with your own hands in 3 options, and you will learn about both traditional methods and folk universal recipes.

The science of how to properly trim ceiling skirting boards in corners is not as difficult as it might seem.

Using a special tool

Miter box

It is recommended for beginners to accurately cut the ceiling plinth using special auxiliary tools. So, for example, professionals adjust skirting boards using a miter box and an electric model.

To know how to properly cut the ceiling plinth with a special tool, just read the quick guide or instructions. The budget option includes a simple hacksaw and a hand miter box. Despite the affordable price and primitiveness of the instrument, if the corners of the room correspond to 45º, the result will be excellent.

When working with a special tool, some features are taken into account:

  • you don’t need a saw to cut a foam plinth, a simple construction knife will be enough;
  • measurements of the length of the ceiling along the mowing line for laying the plinth are carried out in the first place;
  • depending on the model, the miter box allows you to trim for different angles;
  • if there are uneven edges, then it will be more expedient to use a clerical knife.

Pruning with a miter box

To perform cutting with a miter box, perform the following actions:

  • We set the necessary parameters.
  • We insert the first bar, and then a hacksaw for metal.
  • We make cutting.
  • We insert the second bar, which should dock with the first in the same way.
  • Opposite holes are selected, but the angle should be the same, for example, 45º.
  • We make cutting.

If all the actions were performed correctly, then as a result, when joining two plinths, the parts should perfectly match. After that, you can safely proceed to gluing.

It should be taken into account what kind of angle we are talking about: internal or external. The process of trimming the outer corner is carried out according to the following positioning scheme in the miter box:

  • the bar mounted on the left relative to the corner should be applied to the wall of the miter box closest to you with the bottom side up;
  • the hacksaw should be inserted into the near left and far right grooves;
  • the bar installed to the right of the corner is set in the same way;
  • we insert the hacksaw into the near right and far left grooves.

Inner corner trimming

To trim the inner corner, the plinth is laid in the same sequence, and the placement of the hacksaw is different: first, the blade is inserted into the near right and far left grooves, and then vice versa.

A manual miter box requires care and accuracy. If used carelessly, you can easily ruin the ceiling plinth.

Manual pruning

If there is no special tool, then you can manually cut the skirting board elements. We will look at how to cut a ceiling plinth using standard tools:

  • ruler;
  • stationery knife;
  • corner.

Construction knife

  • Measuring the corner of a room using a corner. We put the tool in the corner compartment to the ceiling surface. The indicator should be equal to 90º. If there is a deviation, it can be argued that the corners are uneven, which means that it will be more difficult to cut the plinth.
  • Apply a ruler to the plinth at an angle of 45º. With a sharp clerical knife, cut off the unnecessary part with a sharp movement. If we are talking about a wooden plinth, then first they make markings with a pencil, and then cut with a hacksaw.
  • Checking the correctness of the cut: the ceiling plinths are applied to the corner of the wall. If the work is done inaccurately or there are minor defects, then they can be eliminated with sandpaper (unless the part is smaller than necessary).

If there is an uneven angle, it is necessary to measure its degree, and divide the resulting number by 2. As a result, we obtain the required value for cutting. For example, if there is an angle of 80º, the corners of the plinth should be equal to 40º.

You can adjust the skirting board in place, in this case, follow the sequence of actions presented on

Sticking Guide

In order to easily cope with this stage, which does not imply any difficulties, several basic rules should be taken into account:

  • The fixing of the skirting board starts from the corners in order to immediately carry out the most time-consuming work.
  • It is necessary to dock the elements so that there are no gaps. And the excess glue is immediately removed.
  • After completion, glue the rest of the elements.
  • If the choice fell on a plinth made of plastic, then a finishing putty is used to glue it.

Sticking skirting boards on liquid nails

Sections of fasteners are well moistened with a solution of a primer or water. After the putty is dry, you can proceed to the sealing of seams or cracks. For these purposes, common formulations that are similar to a sealant are suitable.

When choosing compounds for sealing joints, pay attention to the types that are produced on the basis of acrylic.

Ways to form corners

Inner and outer corner

If you are going to decorate the ceiling with a plinth, it should be noted that the corners in the rooms can be internal and external. It is with the latter that difficulties often arise. But thanks to the advice of experts, everything can be done in one of the following ways:

Cutting can be done in the following ways:

  • using a special template tool. miter box;
  • manually according to the markup made by a certain method.

Some features

Going to the market for materials, one should take into account that the assortment is quite large today. Wood and polystyrene take the leading positions among materials.

Wooden ceiling plinth

  • Wood products often look spectacular. With the help of such a plinth, you can hide irregularities, as well as add zest to the interior. To fix the wooden ceiling cornice, you will need self-tapping screws or nails (depending on the wall material).
  • Polystyrene has long occupied a leading position in the construction market. A wide assortment, as well as ease of installation, determine a high demand for products. It is worth noting the excellent decorative qualities.

Expanded polystyrene

When making a choice between the first and second option, take into account the style of the room’s interior.

It is impossible to perform high-quality gluing of the skirting board to the ceiling if you do not cut the corner correctly. It would seem that it is enough just to cut the plinth at an angle of 45º, but in fact, if you measure the angle formed by two adjacent walls, it may not be 45º at all, but, for example, 42º or 50º. As a result, a plinth cut at a 45º angle will not work. In this case, when connecting, gaps and gaps are formed. the general view will be spoiled. Keep in mind that it is easier for novice craftsmen to fit a foam ceiling plinth.

When performing the inner corner, it is necessary to make it so that its lower part rises above the upper one, and the outer one. vice versa.

The finished look of the ceiling and walls can be given by focusing on the plinth for the ceiling, securing it around the entire perimeter of the room. Before choosing it and finishing, it is better to know what you will have to deal with, because the problem for many is the joining of the plinth in the corners. In the process, a lot of difficulties can arise, since the docking angle is not easy to make perfect and even. In this article, we will analyze how to make the corner of the ceiling plinth, doing the job correctly and beautifully.

  • Advice

Any renovation work is always completed with finishing. In rare cases, the interior of the room does without a ceiling plinth, its presence helps to hide the joints of the finishing materials used for wall and ceiling surfaces, in addition, do not forget about the decorative function that this element carries. It is not difficult to arrange the perimeter of the room by simply fixing it in a straight line. It is much more difficult to cut it correctly in the corners without spoiling the material and spending a minimum of time and money.

How to cut?

There are two main questions facing the installation of a skirting board. How to properly cut a skirting board without gaps and with perfect fit in the corners, and what tools should you use to get a beautifully positioned ceiling element in the end? In order to understand these issues, it is necessary to study all the methods and tools used in trimming the baseboard. Almost all methods and tools can be used to adjust the skirting board in both internal and external corners.

Outside corner

For the outer corner, the skirting board is trimmed at an angle of 45 degrees. First you need to check the evenness of the outer corner. If the wall surfaces are in contact with each other at exactly 90 degrees, you can use a miter box to trim the skirting board. In order to properly cut the outer corner planks, it is necessary to correctly position both parts of the skirting board.

First, you need to outline the length of both halves, and only then trim them at an angle of 45 degrees. In order not to change the position of the saw and not to get confused with the location of the halves of the plinth, it is necessary to correctly position them in the miter box. The left half is laid face up, with the part adjacent to the ceiling closer to the center, and the second side adjacent to the wall should be pressed against the slotted sidewall. With the right half, everything is different: it must be laid face down in the miter box, and the location of the adjacent parts to the ceiling and wall here will be the same.

For a straight cut, the bar placed in the miter box must be pressed against the sidewall, placing it as close as possible to the slot. Holding the workpiece with your left hand, you need to carefully make a cut and put it aside. The second half of the skirting board should be cut in the same way, remembering to turn it face down.

In the absence of a miter box, you can make a draft of it on paper or cardboard. First, we draw a rectangle, inside which on the longer sides we draw two more parallel mowing lines. On each side, inside the lines, using a protractor, set the desired angle in different directions. Preparation and subsequent trimming of workpieces is exactly the same as using the tool itself.

This method is good in that you can postpone the angle not strictly 45 or 90 degrees, but a little more or less, because the surfaces of the walls in the corners are not always directed towards each other at an angle of 90 degrees, there are errors. Therefore, for a more accurate cut on the miter box depicted on paper, you can draw any angle using a protractor. The degree of the angle is first checked using a protractor, the resulting value is divided by 2. The resulting number will be the exact degree for the correct undercut.

If desired, you can build a miter box with your own hands. The easiest way is to make a tool out of wood, you just need to take three planks and put them together in the shape of the letter P. Then make marks on the side parts at different degrees, using a hacksaw to make slots. You can also make a miter box from two planks, having previously made slots in them, or use a drawing with the desired angles on paper to accurately determine the slope.

You can even use a table as an improvised tool. The main thing is that he has angles along which he could navigate.

In order to properly cut the outer corners, you can do without any auxiliary tools and drawings on paper at all, you just need to design the future corner in place.

The outer corner skirting board always protrudes into the room by an amount equal to its width, therefore, to determine the exact cut, it is necessary to make marks on the right and left half of the skirting board. You need to set aside the width from the side adjacent to the wall. Then, from the resulting point, lead the line to the upper corner of the half. The resulting triangle must be cut, and the halves must be joined in place for a preview.

The same methods and tools can be used to join the halves of the skirting board in the inner corner. The location of the halves in the miter box when cutting for the inner corner is identical to the location of the parts used for joining the outer corner. But, you do not need to turn the right half of the plinth for a cut, but only change the slope of the cut (use a different cut). In any case, on the left side of the plinth, the line will be angled to the left of the corner point located on the side adjacent to the wall, and on the right side of the plinth, the line will be angled to the right of the similarly located point.

For perfectly flat corner surfaces, you can use a regular square instead of a miter box. To do this, you need to press half of the plinth to the inner corner of the ruler and cut off the unnecessary part at an angle of 45 degrees. It is not difficult to do this, since the side of the ruler and part of the plinth form a total of 90 degrees, the notch line divides this angle in half, which means that part of the plinth will be cut at an angle of 45 degrees.

For wooden and plastic skirting boards, it is not possible to make an incision in place, you can only apply a marking on the surface of the skirting board, and then cut the cut along the mark using a hacksaw or a saw.

In order to properly cut and then join the halves of the skirting board for the inner corner, you need to measure in place with a simple pencil. The right workpiece must be applied to the corner from the corresponding side until it stops. On the ceiling surface, draw a line along the half and remove the workpiece to the side. We do the same with the other half.

At the intersection of the two lines, a point has formed with which you need to make marks on each half of the skirting board. To put a point, you need to attach a half to the docking place. From the resulting point, you need to draw the line to the bottom corner of the half, as a result, you get a small triangle, which you need to cut off.

The halves cut in this way must be adjusted to each other, with inaccurately cut edges, the cuts can be leveled with a knife if the material of manufacture is foam.

To eliminate minor blemishes on the cut of wooden or polyurethane skirting boards, you will have to use a file. Only after complete coincidence of the cuts can you start fixing the halves.

Sometimes you can’t get the perfect fit, but there is always a way out. To eliminate cracks, you can use a putty. The choice of filler depends on the baseboard material. In order to eliminate inaccuracies in trimming the skirting boards, you need to practice using small pieces of the skirting board or cut the planks slightly longer than the intended size. Such a margin will make it possible to make a new undercut in case it was made with the wrong slope or the material at the cut point was deformed.

Features of the

Previously, the ceiling plinth had a different name. fillet. Translated from German means “notch” or “groove”. The material for the manufacture of this decorative element was gypsum, which was poured into a prepared mold. The cured gypsum element was fixed to the ceiling surface with mortar. Today, gypsum ceiling plinth is very rare, its cost is high, and it is much more difficult to install it in comparison with modern counterparts.

Ceiling elements are now available in several types of materials in numerous configurations. They are cheaper than gypsum ones, but they look no worse. The cheapest copies are made from polyvinyl chloride (PVC). This material is subject to deformation with insignificant mechanical stress, the formation of irreparable dents or creases leads to a complete replacement of the element. In addition, all manufactured PVC skirting boards are electrostatic, dust accumulates very quickly on them.

Ceiling plinths made of polyurethane and polystyrene are among the most demanded products. They gained their popularity due to their reasonable price, a wide range of profile patterns, a variety of sizes (their width varies within 5–250 mm), as well as resistance to moisture. Polyurethane ceiling elements can be found in the design of many rooms, they look great in any interior. But, there are also disadvantages, the material does not tolerate temperature changes well, is prone to cracking, especially if installed above a kitchen stove.

The classic version of the ceiling plinth is a wood product. Wooden elements, unlike the listed types, are not installed on glue; self-tapping screws are used to fix them. Plinths made of this material are used to decorate wooden houses or rooms, whose style is dictated by the use of wooden elements.

Required tools

Installing a skirting board means trimming the excess length and adjusting it in the corners. In order to do a pruning, you need tools. The choice of this or that type of tool depends on the material from which the plinth is made.

When working with wood and plastic, use an electric miter saw. Cutting with this tool is accurate, fast and effortless, you just need to set the desired parameters and correctly lay the skirting board. It will not be difficult to choose the appropriate tool, since manufacturers produce this tool in a wide price range.

But, with wood and plastic, you can cope with another well-known carpentry tool. a miter box paired with a hacksaw. This tool is in the form of a tray, made either from wood, or from plastic, or from metal. In the two parallel sidewalls of the miter box, there are slots for the saw, for easy cutting of the plinth at the desired angle. In a simple tool modification, the ceiling element can be cut at an angle of 45 or 90 degrees, and in a more complex version, the plinth can be cut at an angle of 60 degrees.

A miter box and a hacksaw are cheaper than a miter saw, but they also have their drawback. this is the risk of damage to the material, especially if the quality of the purchased material is poor. In addition, the miter box is more suitable for rooms with smooth walls and corners.

For a smoother cut without the risk of damage to the material and without delamination of the structure, a jigsaw is suitable. It is easy to operate this tool, with its help you can set any direction and make the most accurate cuts. For materials lighter in weight and with a less strong structure, you can use an ordinary construction knife, the main thing is to pick up a specimen with a sharp blade.


For a good fit of the ceiling plinth, it is not enough to properly cut and join the halves, you also need to glue them correctly. In order not to later cover up the cracks in the corners or alter the work altogether, you need to adhere to certain recommendations.

  • Before the final installation of the skirting board, it is necessary to properly prepare the surfaces that will come into contact with it. Priming or simply treating parts of the ceiling and wall surfaces will help improve the adhesion between the skirting board and the surfaces.
  • The corners of the room in which the skirting boards are installed should be decorated first. The remaining sections of the perimeter are mounted only after the complete installation of the corner elements.

If there are not only internal, but also external corners in the room, the priority in the design is at the internal corners, since there is a risk of making a mistake with the length of the plinth.

  • In order to fix the ceiling element without gaps, it is necessary to press the plinth quite tightly to both surfaces. It is worth remembering that excessive pressure on some materials can lead to deformation of the element.
  • To avoid glue residues getting on the front surface of the element, you should immediately remove the excess adhesive before it has time to dry.
  • Sealing joints and cracks with a sealant should be carried out only after the glue has completely dried. Compositions with acrylic are most suitable as a sealant.
