How to cut a ceiling plinth: inside and outside corners, fitting uneven corners and joining in rounded corners. How to cut a ceiling plinth with and without a miter box, photo, video Cutting skirting boards to the ceiling

Skirting boards are the finishing touch to any bathroom. And this touch must be perfect or very close to it, otherwise the finish will have an unfinished look, which is fraught with an unaesthetic interior as a whole. The ceiling plinth itself is quite simple to fix, but preparing it for work is not always easy. In particular, without knowledge of the matter it is difficult to make a neat corner - in an attempt to get beautiful strips, you can ruin a lot of consumables. So that you avoid such an unpleasant situation in the process of repairing your bathroom, then we will tell you how to properly cut the baseboard in the corners: what tools to use and what methods you can resort to.

Trimming skirting board corners with a miter box

First, let's figure out how to properly cut the corners of the plinth using a miter box - a carpentry tool that is a tray in the shape of an oblong inverted letter "P". This tool has special slots for cutting parts at angles of 45 and 90 degrees: a workpiece is placed inside the miter box, a hacksaw is inserted into the guides and the workpiece is cut at the required angle.

At first glance, everything is simple, but in the case of skirting boards, there is a risk of getting confused in the sides of the planks and making a marriage. In order to prevent this, we recommend that you work according to the following schemes.

Required Tools

For outside corner:

  • With the side that will be directly attached to the ceiling, lay the plinth on the bottom of the miter box. With the other side, press the product against the wall of the tool, or rather, against its right slot.
  • Cut off the required part of the plank using a hacksaw or utility knife.

Advice. Cut the baseboard without excessive pressure, so as not to provoke the appearance of chips and not to deform the workpiece.

For inside corner:

  • Press the plinth to the bottom of the miter box with the side with which it will be fixed on the ceiling. With the other side, press the bar to the left slot.
  • Cut off the corner. Attach the resulting bar to the first product and check how the sawn parts fit together. If gaps remain, carefully correct the blanks with a knife. At the same time, if the error is small and you are not sure that you can carefully work with a knife, choose an easier way - after sticking the plinth on the ceiling, mask the gap with putty that matches the color.

Trimming a plinth without a miter box

Agree, not everyone in the household has a carpentry tool, and buying it only for a baseboard is not a very successful idea. But you still need to cut the corners, because the accuracy of the ceiling finish is at stake. How to be in this case? In fact, you can completely do without a miter box. There are even two ways to cut the corners of the baseboard without a special tool: by resorting to marking on the wall and using a painted false miter box. Let's start with the first one.

You will need:

  • hard pencil;
  • ruler;
  • utility knife or hacksaw.

The work is carried out as follows. For inside corner:

  1. Attach a bar to the ceiling, which will be installed to the right of the corner. Draw a straight line across the ceiling along the outer edge of the baseboard.
  2. Attach the plank to the opposite side of the corner and also draw a line on the ceiling.
  3. Mark the place where the two lines meet with a cross. Attach the bar to the corner and transfer the resulting mark to it, and then draw a neat line from it to the bottom corner of the workpiece - along this line you will need to cut the plinth.
  4. Cut off the required angle with a hacksaw or utility knife.

Trimming a plinth without a miter box

For outside corner:

  1. Attach the plank to the right of the corner. Draw a line across the ceiling along the baseboard away from the corner.
  2. Attach the plinth to the left of the corner. Draw a line along the plank to where it intersects with the first line.
  3. Transfer two marks to the bar: the first is the intersection of the lines on the ceiling, the second is the place where the corner of the room passes. Connect the two marks - you will get a plinth cutting line. Now it remains only to cut off the corner and, if necessary, adjust the gaps.

Trimming a corner with a false miter box

The third way to trim the corner of the plinth is not quite ordinary - using a kind of false miter box. There are two ways to make such a "tool".

The first is to draw a miter box. To do this, you can use ordinary thick paper or cardboard: draw two parallel lines on the sheet and, using a protractor or a simple square, set aside the corners with the required degree. The corner is cut off in almost the same way as in the case of using a joiner's miter box: attach the plinth to the "tool", make the necessary marks and make an incision along them.

The second way is to make a prototype of the miter box from three wooden planks: connect them in the form of an oblong letter “P” and make cuts at 45 and 90 degrees. You can use the same protractor to mark the corners.

A miter box made of wooden planks

When cutting the corners of the plinth without a miter box, it is very important not to miscalculate with the length of the plank and directly with the degree of the notch. In order not to be mistaken, at first it is better to cut the blanks 10 cm longer, then try them on dry to the ceiling and after that adjust until you get the desired result. In addition, let's not forget that not all bathrooms have ideal 90-degree angles - you still cannot do without adjusting the products.

Advice. You need to fix the skirting board to the ceiling only after you adjust the corner of the next skirting board blank to it. Sections are best tried on not under the ceiling itself, but on the table - it will take more time, but the cut lines will be more accurate.

Thus, we have several ways to trim the ceiling plinth at once: with the help of a joiner's miter box, without a miter box, using a kind of false miter box. Whatever option you choose to make the corners, it is important to do everything carefully and carefully - only in this case you will get a truly effective tool for the final decoration of the ceiling, thereby making the interior of your bathroom aesthetically complete.

There are more than enough tips on how to cut a plinth at 45 degrees on the net, the only bad thing is that most of them are given by people who have never done this. Further, from the point of view of 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 cut ceiling moldings in corners is not as complicated as it might seem.

A few words about tools and materials

Floor skirting boards are now made of wood or polyvinyl chloride (PVC), in other words, plastic. Ceiling fillets have a slightly longer list:

The range of ceiling plinths is much wider than that of the floor direction.

  1. Polyurethane - these skirting boards have good elasticity and can bend around radial and other curved surfaces, but in any case they need to be cut at clear angles;
  2. Styrofoam - the simplest budget option, the price of foam plinths is low and they are cut very easily;
  3. PVC - the principle is the same as for floor skirting boards, but the model range is much wider;
  4. Wooden - similar to the floor, only there are still wide models;
  5. Gypsum - with the advent of polyurethane and foam, gypsum ceiling fillets faded into the background, firstly, they are heavy, and secondly, fragile. But in fairness, it's worth mentioning them.

Since it is impossible to properly cut the ceiling plinth and its floor counterpart without a good tool, we will dwell on this issue in a little more detail.

The best, almost ideal tool for cutting any skirting boards and not only is a miter saw with a rotary bed. The high-speed disc makes smooth and precise cuts, and the bed in these units rotates to any angle. The only problem is the serious cost of this tool.

A miter saw is almost the perfect tool for cutting skirting boards and more.

It is believed that one of the best hand tools for accurately cutting small bars is a backsaw. In principle, this is true, but I’ll tell you honestly, a really high-quality saw, even with the current assortment, is not easy to find. If you still decide to buy such a tool, then take a saw with a fine tooth.

Theoretically, foam and polyurethane can be cut with any sharp and durable knife. But at the same time, you need to have a steady hand and at least a little experience in cutting foam. Plus, cutting wide fillets with a knife is very problematic.

Without experience, making a clear cut with a knife is very problematic.

Personally, in the absence of trimming, I use only a hacksaw for metal. It is suitable for cutting absolutely any material, from foam to wood. By the way, the question is often asked how to cut a plastic plinth for the floor, and so - take a hacksaw for metal and you definitely can’t go wrong.

For cutting skirting boards, a hacksaw is considered one of the best tools.

Three ways to cut skirting boards

For floor and ceiling plinths, the cutting instructions are almost the same. But if on the floor a 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 ceiling skirting boards.

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 bed and sawn 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 plinths are applied to the side of the miter box that is closer to you, and floor plinths, 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 plinths, since the miter box lies on a horizontal plane, it is easier for you to navigate in the position of the plinth. People most often make mistakes when trimming a ceiling fillet; they are simply incorrectly put into the tool. There is a simple but important rule here.

Important: the edge 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 the ceiling is placed on the bottom of the miter box.

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

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

Professional miter box with the ability to fix a hacksaw and parts.

The swivel device can be safely called a "pocket" miter box. Of the advantages here, only the possibility of a clear fixation of the angle of rotation of the bar. On the one hand, it’s easy for them to work - I set the corner, attached it to 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.

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

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

Method number 2. Trimming according to the template

Most often, both ceiling and floor skirting boards need to be cut at 45º. If there is no specialized tool nearby, then an impromptu miter box can be drawn on a notebook sheet. From the school geometry course, we know that the diagonal of any square with respect to the base has an angle of inclination of 45º.

Next, you need to draw a square and draw 2 diagonals in it - these will be the desired 45º. You just have to correctly attach the plinth to the leaf and mark. True, in order to cut the plinth evenly without guides, you need a good eye and a faithful hand.

Method number 3. Applied universal

A 45º cut is a common option, but what if you need a different angle and only have a hacksaw and a pencil? It turns out that there is a very simple way out of this situation. Plus, this method is universal, it is suitable for both external and internal corners.

Moreover, I can assure you that those angles that visually appear to be straight, in fact, have deviations of a couple of degrees. As a result, you buy a good tool, cut off clearly 45º, and when docked, a gap between the baseboards “crawls out”. Here this problem disappears. And then, using an example, we will consider how to cut the ceiling plinth in the inner corner.

Illustrations Recommendations

Stage 1.

Take a fillet, apply it on one side of the corner and use it to draw 2 lines, along the wall and along the ceiling.

Tip: to make the lines inconspicuous, they can be drawn not with a pencil, but, for example, with a nail or a knife edge.


Stage 2. Do the same on the adjacent side of the corner.

Stage 3. If you draw a diagonal from the intersection of the lines on the ceiling to the inner corner, then you will get the desired cutting line.

Stage 4. Then take the tool and cut according to the finished markup. If you normally own a hacksaw, then the skirting boards should converge perfectly.

. As I already mentioned, exactly the same technology can be used to trim the outer corner.

Important nuances

If you tried as best you could, but a small gap at the junction nevertheless “crawled out”, do not be discouraged. In wooden fillets, such a gap is easily smeared with furniture wax. To cover the gap on the baseboards made of polyurethane, foam, plastic or gypsum, putty is perfect. Naturally, the color of the composition must match the color of the baseboard.

All cracks in the area of ​​\u200b\u200bceiling fillets are sealed with putty.

Wide ceiling fillets are certainly beautiful, but they can only be mounted on perfectly flat walls. If the plane of the wall in relation to the ceiling is a wave, then it is better to buy narrow polyurethane fillets, they are elastic and will smooth out this drawback.

Most of the questions arise about how to cut the wallpaper under the ceiling plinth. There is nothing complicated here: the wallpaper is glued with a slight overlap on the plinth, and when the wall is completely glued, take a large spatula, put it in a corner and cut off the excess with a knife.

But keep in mind - neither a knife nor a spatula can be torn off the wall until you have passed the entire plane. That is, they put a spatula from the corner, cut off the wallpaper along the length of the blade, and then without lifting the blade from the wall, move and cut until you reach the next corner.

Conclusion

All three methods I have described work, the choice depends on what tool you have available and what your professional skills are. If after watching the video you still have questions, welcome to the comments, I will help as much as I can.

If you are not confident in your abilities, then for both floor and ceiling plinths there are docking elements that allow you to do without trimming.

In many apartments and houses, the ceiling plinth (fillet) is the final design element that completes the interior of the room. The main difference between a ceiling plinth and a floor plinth is that minor errors are permissible when cutting the latter, because it can be puttied and painted. Cutting the corners of a ceiling plinth requires the highest precision. In this article, we will tell you how to properly mark and cut the ceiling plinth, so that after installation in place, all the elements fit snugly together and there are no gaps.

What is the ceiling plinth made of?

The most popular materials for the manufacture of ceiling plinth are:

  • foamed polyurethane;
  • Styrofoam;
  • expanded polystyrene.

All these materials are characterized by low mechanical strength and ease of processing. They can be cut both with a hacksaw for metal and with an award, a special hacksaw for wood for fine work. Trimming with a knife is not recommended, because a correctly marked and cut corner does not need to be adjusted, and if the marking or trimming is done with violations, then it will not work to correct the situation with a knife, as on wooden floor skirting boards.

Corner marking

First, the plinth must be marked. There are two ways. The first is suitable for external and internal corners of 90 degrees. The second method is suitable for any angles. The essence of the first method is that a standard carpentry miter box provides a cut of any material at angles of 90 and 45 degrees. Therefore, only the corner of the wall is marked on the plinth, that is, the short part of the plinth angle. Then they are laid in a miter box and cut at an angle of 45 degrees. The second method is more complicated, but much more reliable. A plinth is applied to the junction of the wall and ceiling and it is noted where the outer edge passes. Then a plinth is also applied on the other side of the corner. The point of intersection of the marks is the outer edge of the skirting joint, and the corner of the two walls forms the inner edge of the joint.

In this case, it is necessary to take into account the direction of the corner, because inexperienced finishers sometimes confuse it and the joint has to be redone. After that, the appropriate markup is applied to the plinth. This can be done either by measuring the distances of the markings on the ceiling, or by attaching a piece of plinth to the junction of the wall and ceiling and marking the outer and inner edges on it. After that, the plinth is placed in a miter box with a variable angle and carefully cut off. If there is no such tool, you can use an ordinary wooden miter box by cutting the appropriate grooves in it.

How to cut a skirting board - Video

There are several rules that will help you make an even cut on any baseboard:

  1. Be sure to use a miter box and never cut "by eye", this will lead to cracks.
  2. Position the skirting board so that the main cutting force is directed towards the vertical wall against which the skirting board is pressed.
  3. If you cut the other way, the baseboard will move, causing scratches and damage to it.
  4. To cut the plinth, use a sharp tool - a hacksaw or an award. If the blade becomes dull, replace it.
  5. Move the hacksaw with smooth movements without jerking, keeping the blade strictly parallel to the floor or table.
  6. Before cutting the skirting board to size, practice on unnecessary pieces, this will help to fill your hand.

Methods for cutting a ceiling plinth for joining in internal and external corners using a miter box, a template, or a wall marking method. Tool selection rules and useful tips.

The content of the article:

One of the most difficult steps in the installation of ceiling plinths is their correct cutting. Only by correctly joining the individual elements at the outer and inner corners, you will get the desired result. Fillets will look aesthetically pleasing and neat if they are cut at the right angle and the gaps are sealed. To perform this task, a special tool (miter box) is used. And if not, then other devices will help.

Selection of tools for cutting ceiling plinths


To correctly and accurately cut the ceiling plinth, you need to use a tool suitable for cutting. It is chosen depending on the material from which the fillets are made:
  • Styrofoam. It has low strength and is relatively inexpensive, and therefore foam models are becoming more and more popular. Their strength does not particularly affect performance, since usually the ceiling plinth is not subjected to mechanical stress. For cutting, a regular clerical knife is suitable.
  • Extruded polystyrene foam. A cheap material whose density is several times higher than that of polystyrene. Because of this, cutting it is a little more difficult, and therefore a sharp and thin knife is used for this purpose.
  • Wood. Such skirting boards are more difficult to process, although they have many advantages (environmental friendliness, strength). They cost more
    especially if they are made of hardwood. Before cutting the ceiling plinth from wood, stock up on a hacksaw.
In addition to a tool for directly cutting a baguette, you will need a miter box. This is a special device made of wood, plastic or metal in the form of a box with notches on the sides. A hacksaw or knife can be inserted into it at the desired angle. Thus, the cutting angle is obtained as accurately as possible.

It can be purchased at a hardware store or made by hand according to the following instructions:

  1. Three boards 50 * 15 cm are knocked together with a long edge into the shape of a three-sided, rectangular box. Please note that a 90 degree angle must be observed between the side bars and the transverse plank.
  2. Using a protractor, mark an angle of 45 degrees on the bars. Instead of a protractor, you can use a school square. In it, one angle is 90 degrees, and the other two are 45 degrees.
  3. Before cutting corners, mark the vertical direction with a simple pencil.

To work with this home-made device was convenient and safe, the boards must be well sanded before fastening.

Technology for cutting ceiling skirting boards

For prompt and high-quality work, you need to choose a tool in accordance with the material of the plinth and choose a cutting method. If you have a miter box, then there will be no particular difficulties in the process. If it is not there, then two options are possible: cut according to the template and measurements on the ceiling, or make this tool yourself.

Features of cutting ceiling plinths in a miter box


It is necessary to work with this device extremely carefully so as not to dull the tool and not to leave gashes in unnecessary places. In the process, we adhere to the following instructions:
  • We fix the baguette in the miter box in the way it is planned to place it on the wall. The side that will be pressed against the ceiling on the miter box should be adjacent to the sidewall.
  • We insert a cutting tool (hacksaw or knife) into the desired gap and cut the fillet.
  • We process the junction of the ceiling plinth and apply it to the wall to check the correctness. The foam molding can be corrected with a sharp knife, if the unevenness of the end is about 2 mm. Wooden plinth can be simply sanded with sandpaper. For ease of use, it can be glued to a wooden block.

When cutting and trimming foam and polyurethane products, remember that these materials crumble and push through, so the tools must be sharp enough, and a strong mechanical impact on them is undesirable.

Technique for cutting ceiling plinths according to a template


This method can be used if your corners are even and you want to cut the baguette exactly 45 degrees. To do this, before cutting the ceiling plinth in the corners, you need to draw a miter box on thick paper. We draw two parallel lines and mark the angles at the desired degrees using a protractor.

We place the fillet in this case in the same way as on a traditional miter box. Please note that you need to cut the plinth while holding the tool in a strictly vertical position.

Rules for cutting ceiling plinths by marking


This method is used to cut the plinth in cases where there is neither a miter box nor parts from which it can be made.

To do this, you need to make markings on the wall in this order:

  1. We apply the baguette in the corner to the place of fasteners.
  2. On its one edge, we draw a base line for the mounting level on the ceiling.
  3. We apply the fillet in the same way to the perpendicular line drawn on the ceiling and again draw a straight line along one side. We should get two segments that intersect at one point.
  4. We again apply two skirting boards in turn and mark this point on them.
  5. We repeat the same procedure now on the wall to mark the place of cutting from below on the products.
  6. We connect two points with a line. It can run at an angle of 38-45 degrees, since the walls and corners in living rooms are often uneven.
  7. Cut off the baguette along the drawn line.

When cutting in this way, it is important to accurately draw all the lines and mark the points. An error of even a few millimeters will cause a gap to form. This method is suitable for cutting and joining both the inner and outer corner of the ceiling plinth.

Method for cutting a ceiling plinth without a miter box


To neatly dock in the inner corners of the fillet, you can do without a miter box.

We perform the work in the following order:

  • We apply the end part of the baguette to a sheet of paper and trace the contour of the convex side. It is more convenient to use a small piece of plinth (if any).
  • Cut out the resulting template.
  • We transfer the contour to the surface of the baguette with a simple pencil.
  • Cut along the drawn curve.
  • To try on, we apply one skirting board tightly with its end part to the wall, and then the second.
  • If there are small gaps, then they can be processed with a clerical knife or subsequently sealed with sealant.


When working with a miter box, you need to consider two points:
  1. The inner corner of the ceiling plinth is formed from two elements: the first is inserted from the right into the miter box and cut from right to left, the second is wound from the left and cut from left to right.
  2. We start the first part of the outer corner on the left and cut it from right to left, we start the second part on the right and cut it off from left to right.
In addition, you need to know such nuances before cutting the plinth:
  • Before you start cutting a baguette with a miter box, try cutting off a trial plank to avoid mistakes.
  • Correct measurements can be made by measuring the length of the inner corners of the plank along the inner side, and the outer ones - from the point of the inner corner to the width of the fillet deep into the room.
  • If the baguette is installed under a stretch ceiling, then it should be attached only to the wall. In no case should the adhesive composition get on the vinyl sheet.
  • The final fastening of the plinth should be carried out only after the precise fitting of the plank.
  • If the corners and walls in the room are even, then fitting can be done on the floor.
  • When installing baguettes, it may be necessary to adjust them several times, so stock up on tools and patience.
  • Instead of a template and miter box, you can cut in the corner between the wall and the floor, or by moving a table against the wall. In this case, on the wall, ceiling and baguette, the angle of cutting off the end should be noted.
  • If you are interested in the question of how to cut a ceiling plinth without a miter box, and you do not have time to use templates, then you can purchase special corner inserts in advance. They will hide the gaps, but will protrude and stand out on the coating.
  • If you have a plinth made of precious woods, then you need to cut and install it very carefully, since a large amount of putty for sealing joints will be too noticeable, and painting over a baguette is an inappropriate solution, because this way you will hide the natural texture of the array.
  • Styrofoam products do not have to be fitted end-to-end due to the softness of the texture, but wooden and plastic models must be well joined.
  • If trapezoidal niches on the wall need to be bypassed from above with a plinth, then we join the piers at an angle other than a straight one.
    In this case, we cut the plinth at an angle equal to half the joint. For example, if the walls are joined at an angle of 120 degrees, then we cut the fillet at an angle of 60 degrees.

Repair is a responsible and costly undertaking. Although you can save a lot if you do the work yourself. Cosmetic finishing of premises is carried out according to certain technologies. You can decorate the interior using a variety of materials.

Today, a very popular technique is the use of ceiling plinths to hide irregularities between the walls and ceiling. In order for the contour to be aesthetic, it is necessary to do the work carefully. How to cut corners on ceiling plinths, the advice of experienced construction and repair craftsmen will help you understand. They will tell you how to use various tools to perform the necessary manipulations with decorative finishes of various types.

General characteristics of the finish

When studying the question of how to properly cut a corner on a ceiling plinth, you should familiarize yourself with the features of such a finish. Stucco molding between the ceiling and walls is now made of artificial materials. It can be polyvinyl chloride, polystyrene foam or polyurethane. Wood can be used from natural materials.

In the construction business it is called (scientifically) a fillet. Of all the materials from which such trim elements are made, polyurethane is considered the highest quality. Therefore, it is better to choose it. Next, let's try to figure out how to cut a corner. Expert advice will help you do this job well.

Skirting material

Experts agree that polyurethane is the best material for the presented finishing products. But even it has a number of shortcomings. These should be taken into account before cutting corners on ceiling moldings. Polyurethane is subject to temperature fluctuations. Therefore, it is not used for decoration in the kitchen or bath. Otherwise, the skirting boards will quickly crack and lose their aesthetics.

Expanded polystyrene has almost all the positive characteristics inherent in polyurethane. But it is still more fragile material. It's easy to break.

Skirting boards made of PVC are relatively cheap. But it is very easy to leave dents or potholes on them. Therefore, it is necessary to work with such products very carefully.

Wood looks very beautiful, but not in all interiors. In addition, it is quite difficult for an unprofessional master to work with such material. Would you like to do your own repairs? Then you better still choose polyurethane or expanded polystyrene.

Form, fittings

When studying the question of how to properly cut a corner on a ceiling plinth, attention should be paid to its shape and related products. There are embossed and smooth fillets. Their width and length can vary significantly.

When choosing the size of the skirting boards, the type of interior, as well as the height of the ceilings, are taken into account. For a small room, where the floor-to-ceiling distance is no more than 2.75 m, wide skirting boards will not work. They will look out of place. For the same reason, a narrow fillet should not be used for high ceilings. In such rooms, a 45 mm plinth looks good.

For installation, you can purchase curly corners from the same material as the fillet. They are external and internal. But quite often the skirting boards are joined without them, directly. In this case, you need to perform a smooth, beautiful trimming of the corners.

Preparatory work

To make the process quick and easy, use a tool such as a miter box. This is a U-shaped template. There are slot patterns in its side walls. They have different angles.

There is another technique that allows you to evenly glue the ceiling plinth. It is possible to cut corners without a miter box. But still, the use of such a tool greatly facilitates the work.

First you need to mark the plinth. If you want to create an external corner, measure the length along the ceiling, internal - along the wall. For fillets, a line slope of 45 and 90 degrees is used. Since this is a fairly small number of slot options, it is quite possible to make a template yourself. All you need is a sheet of paper or cardboard.

If the repairman has considerable experience in carrying out such operations, he can cut corners without additional tools. The master attaches the fillet to the wall, and then makes marks on the product right here. After that, he cuts off the excess. An inexperienced master, most likely, will not be able to cut even corners the first time. Therefore, it is better to use a miter box or close the irregularities with decorative corners.

Inner corner

First of all, it is necessary to consider the technique of how to cut the inner corner of the ceiling plinth. After all, they are in every room. If there are no external corners in ordinary rectangular rooms, then these varieties will have to be cut out anyway.

A plinth is placed at the bottom of the miter box with the side that will adjoin the ceiling. The lower part of the fillet will be pressed against the wall of the tray.

If the material is hard, it is cut with a metal saw. Soft products are easily processed with a sharp knife. The angle should be 45 degrees. If the pressure during cutting is too strong, hooks and chips will form on the plinth. cut in the same way.

Before gluing, they are applied to the wall and, if necessary, correct small irregularities. There should be no gaps between the skirting boards. If this is the first time such work is being done, you can practice in small pieces.

outside corner
