How to cut a skirting board by marking the ceiling

Before you cut the outside corner of the ceiling plinth without a jigsaw, you need to decide which method is the most appropriate. The easiest way is to mark the ceiling with a pencil.

In the absence of special tools, you can use a simple set of things: a pencil, a stationery knife, tacks and glue for decorative parts. You will also need a ruler.

After the baguette is placed on the ceiling, a corner mark is made. In the place where the junction of the two ties will be formed, put a cross or a large dot. Then, on the floor or on the table on the skirting boards, a cutting line is carried out. If the baseboard is PVC it can be easily trimmed with a utility knife. Those who have never performed repair work, you may need the help of a master, if the room is uneven, convex corners. Before gluing it is recommended to make a control measurement.

How to cut the baseboard at any angle and without gaps. 3 working ways from the practice

Advice on how to cut the baseboard at 45 degrees on the network is now more than enough, the only thing is that most of them give people who have never done it. Next, I will tell you from the point of view of practice how to trim baseboards on the corners with their own hands in 3 variants, and you will learn about both traditional methods, and folk universal recipes.

The science of how to properly trim ceiling baseboards in the corners is not as complicated as it may seem.

How to trim a ceiling baseboard inside corner

When we assess the new repair, then unwittingly direct our eyes, first of all, to the ceiling. No matter how stunning the interior would not be, his estimate of the curved joints finish will fall sharply. In this article, we will give instructions about ceiling baseboards. how to make the corner joint perfectly even.

Having completed the finishing of the walls and ceiling, unwittingly there will be ugly transitions between them. To this end, and use the tape at the transition point of the two materials. When installing them, it is important to maintain the evenness and neatness of the joints. Article on the topic: how to glue the ceiling plinth on the glue and putty.

Professional jigsaw with a rotary hacksaw For a long time, carpenters have invented such a special box with slots. a jigsaw. It is easy to recognize it, among the variety of repair tools, by its distinctive appearance. This is the most convenient and indispensable device in solving the question, how to cut the corners of the ceiling plinth.

The jig is usually in the form of a tray with vertical holes for a hacksaw. It can be made of wood, metal, or plastic. This tool represents the oldest and simplest carpenter’s tool for cutting wooden parts at 90 and 45 degree angles. There are types of such a device and for professional work, with a rotating mechanism, in them the cutting tool can be rotated and fixed in any position.

How to properly cut a ceiling plinth Ceiling corners can be divided into internal and external, the way of joining them is slightly different.

If necessary, you can make a plier with your own hands. You can use 3 scraps of plywood or boards of equal size. First of all, you need to enclose them in the form of an inverted “U”, and make a marking of the corners. Then, according to the markings, cut notches under the hacksaw almost to the bottom, and the boards are twisted.

  • Take proper measurements.
  • After that, set the baseboard plank in the jig so that this position exactly coincides with the placement on the ceiling.
  • The skirting board must be pressed firmly against the opposite wall of the jigsaw. Hold and press with the left hand.
  • We put the hacksaw at an angle of 45 degrees in a special hole and cut the piece.

When cutting soft materials (PVC, Styrofoam) use a metal hacksaw or a regular construction knife. Then your work will be neat and with straight edges. To cut it accurately, you need to start cutting it from the front.

  • Measure the length of the baseboard from the nearest wall to the outside corner, leave a pencil on the underside, marking the desired length. Note that the edge (its upper part) must protrude a little.
  • Move the skirting board into the joiner and cut it off.
  • The adjacent slat must also be measured with a reserve, and cut off in a mirror reflection to the first part.

Let’s try on the ceiling plinth. the joining of parts should be perfectly even. If the result is not achieved, and at the joints are protrusions. you can trim the edges with an ordinary knife until the perfect junction.

Checking the even junction In the video in this article, all the nuances are well described:

The second method. without additional tools

For the inside corner you can use the easiest way to make a perfect join. by marking on the ceiling. Another example of how to cut a corner nice and flat.

The end result is an even 45 degree angle if you run a fishing line from the intersection point to the edge of the piece. This way how to cut a plinth is accessible to everyone, without the presence of special tools.

With a good eye and hand accuracy, you can use a homemade template, which resembles an imitation of a jigsaw. To do this, take a thin board or heavy plywood, and draw a layout in the form of a horizontal rectangle. Using a protractor, mark 45 degrees, on the right and left sides of the rectangle. Draw a scythe line connecting the opposite edges.

Now you can solve the problem of how to cut the ceiling plinth, using this layout. The actions are simple and similar to the description above in the first option. Only the ceiling parts should not be inserted, but overlap the drawing and combine the hacksaw with the layout marking.

Special accessories for the joint Installing ceiling plinths, you can bypass the question of how to cut the corner of the side. In a situation where you do not want to cut anything, if you are a woman and you like beauty, not carpentry, you can go another way. Choose a skirting board for your finishing, to which you will find in the store, a part matching the pattern, closing the joint. This method will save you time and effort.

How to cut a ceiling plinth and a floor plinth

The most difficult thing to install ceiling and floor skirting boards. is to design a corner. Docking strips in such places must be very carefully, otherwise the appearance of the decor will be hopelessly spoiled. Of course, you can use quite aesthetically pleasing special corners.

However, docked naturally docked strips usually look more harmonious. Yes, and to spend on additional details in this case do not have to. Therefore, further in the article we will consider how to cut the corner of the ceiling plinth correctly and what to process the seam.

Ceiling skirting boards are made from a variety of materials. foam, polyurethane foam. plastic, wood. To trim them, you can use the tools that are available in every home. Styrofoam strips are cut with scissors or a knife. Wooden baseboard is cut with a wood hacksaw. How to cut a plastic skirting board is also not a question. It can be sawed with an ordinary metal saw.

Wooden baseboard is trimmed with an ordinary hacksaw

For accurate and most precise trimming of ceiling plinths, a special tool is usually used. the plinth joiner. It is a tray made of three boards. Its walls have slots located at a certain angle to the axis (45, 60 and 90g, etc.д). They are designed to guide the blade of the hacksaw when cutting. You can buy a squeegee for ceiling plinths in a construction store.

Trimming boards at a 45gr angle is done with a hacksaw

Trimming in the jigsaw is done as follows:

Important: When trimming, remember that when decorating the inner corner, the edge of the baseboard adjacent to the wall should be longer than the one adjacent to the ceiling. When finishing the exterior. on the contrary.

The strips are attached to the corner, and the adjustment is made

The corner is best glued before installing the baseboard on the walls

So we with you found out how to file a ceiling plinth (video above probably will help someone to understand it better) using a plough. But what to do if this tool is not at hand? It is actually possible to evenly fit the skirting boards without using it. There are two main ways of doing this: marking directly on the wall and making an imitation of a jigsaw.

In the first case, the procedure is as follows:

How to properly cut a ceiling plinth without a chisel. Leading the first line

A second fishing line is carried out and a mark is placed on the baseboard

Then the actual cutting of the skirting board at an angle is performed using the obtained scythe line.

Without the use of a tray, the slats in the corner can be mounted quite neatly

In order to cut an even corner, you can also use the imitation of a chair:

How to connect the strips if the angle is uneven

In urban apartments, and especially in older apartments, the walls are rarely even. Therefore, the corners between them are often not straight at all. How to cut the ceiling plinth in this case?

This is actually not as complicated as it might seem at first sight. You just need to measure the angle. To do this, you can use a special tool malka or simply make a template from paper and use a protractor.

Uneven angle can be measured using a small angle gauge

The resulting corner is divided in two, we draw a corresponding “notch” on the plywood and cut the strips. Next, you will just need to perform their connection on the glue.

How to cut the corner of the ceiling plinth we found out with you. Now let’s see how to finish the joints. How to seal the joint in the corner? In the event that there remains a small gap, sealing can be done with ordinary putty in the color of the baseboard. The joints can also be passed with silicone sealant.

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

Important: You can seal only the inside corner with putty or sealant. The outer one should be fitted as carefully as possible. Even a small gap to remove subsequently unnoticed here is simply impossible. Especially when the baseboard is wide.

Corner elements for the ceiling plinth

The trimming of the ceiling slats when using angle elements (special connectors) is also usually done in a jig. How to file the slats in this case? Everything is very simple. the cut is made at right angles. In the absence of a tray, you can use an ordinary protractor or a square. Corner elements (photo):

When using corner elements cut strips at right angles

How to properly trim a floor baseboard

Floor skirting boards can be made of PVC. polyurethane. Wood or fiberboard. The same as in the case of the ceiling skirting boards to saw them, depending on the material, with a regular hacksaw (wooden) or a hacksaw for metal (plastic).

Now you know how to file a ceiling plinth. Next, let’s see how the fitting and trimming of the floor. How to use a jigsaw in this case? When trimming a floor baseboard, the procedure is about the same as when trimming a ceiling. For the inner corner:

The strip is inserted into the tray and pressed down firmly

How to cut a ceiling plinth for outer and inner corners

Tip: A 45g end is worth doing not only to cut the elements in the corners, but also to make the joints on the wall itself. In this case, the joints will not be as noticeable.

So we have considered in the most detailed way how to cut a skirting board in the corners. The procedure is not as complicated as it may seem at first glance. Once you start trimming in a jigsaw or with its imitation, you will see for yourself.

How to cut a skirting board properly

This is how the corners of a properly cut ceiling skirting board look like

This is the perfect ceiling plinth you can make with your own hands if you follow these instructions.

For the manufacture of ceiling mouldings are mainly used three materials, this:

Stucco ceiling mouldings are also made, but that’s another topic.

  • The most fragile and cheapest of them is foam, although the strength of the ceiling is not very required.
  • Styrofoam is much denser it can be easily cut with a knife and, of course, it is more expensive.
  • The most difficult to handle wood. To make the corners of wooden baseboards were perfect, you must use only a fine-toothed hacksaw, or even better a hacksaw for metal and sandpaper. Only then is it possible to achieve an even angle

Trimming ceiling plinth with their own hands

Let’s review step by step how to properly cut the corners of the baseboard (also called baseboard fillet). In the vast majority of modern apartments, the corners of rooms and other rooms are 90°. Cut the ceiling skirting boards must be at an angle of 45 ° or 90 °. How to trim a ceiling plinth? To do this, a special tool called a plier is used. In this tool is already made slots at an angle of 45 ° and 90 °. The seemingly simple task of cutting a baseboard. But the fact is that it is glued to the ceiling at an angle of 38 ° to 45 °, which means that the cut corners will not join, leaving gaps. To prevent this from happening, and use a chair.

Cut the inner corners of the skirting boards with the file

To do this, you will need such tools:

  • Tack is placed on the bottom of the chair by the side that will be glued to the ceiling, and the underside is pressed against the wall of the chair, to the right of her slot.
  • Trimming the baseboard is performed with a hacksaw or sharp knife. It should be cut carefully, without excessive force so as not to deform the ceiling ledge and not to create splinters.
  • In this way we trim the adjacent corner of the skirting board, but already using the left-hand slot in the jig saw.
  • Then these parts are attached to the corner to check if there is a gap, it is possible to trim with the knife.

Tip.In order not to transfer material in vain and acquire skills, train first on small pieces.

How to properly lay the tack in the chair

Cut the outer corners with the plinth cutter

  • Put the skirting board at the corner and mark the place on the skirting board where the outside corner begins with a pencil.
  • Then fit the skirting board into the joiner. The side that will be attached to the ceiling, lay it on the bottom of the mortar, and the other side pressed against the wall.The mark on the skirting board must be near the left-hand slot. Cut one edge.
  • Then in a similar way cut the other half of the corner. Only the mark on the skirting board must be near the right-hand slit.

Press both halves of the skirting board onto the corner and check if there is a gap. If everything is OK, we can glue the skirting board in place.

How to cut a skirting board without a mitre cutter Cut a skirting board for the inside corner

If you don’t have a joiner, you can do without one:

  • To do this we put the skirting board on the ceiling the way it should stand and run a fishing line along the ceiling.
  • Then we put the skirting board to the ceiling to the right of the corner and spend the second fishing line.
  • At the point where the mowing line crossed, make a mark on the baseboard and guide the line from the mark to the bottom corner of the baseboard. This line will be the trim line of the skirting board.

Marking for trimming the left-hand corner of the skirting board

Do the same with the left corner. Cut along the lines with a sharp knife.Then we put it to the corner and check if there is a gap. If there is a gap, carefully trim the corners. Then the skirting board can be glued in place.

Advice. Do not use much force when trimming the baseboard. It can crumple and deform after you glue it in place after the glue dries.

The marking for trimming the right corner of the baseboard without the jigsaw

Without the joiner, you can easily cut the skirting board for the outer corner as well:

  • Position the ceiling finish as it is intended to be at the right-hand corner. Guide the line with a pencil on the ceiling beyond the corner.
  • Then we attach the fillet to the left of the corner and guide the fishing line along the ceiling until it intersects with the first line.
  • On the baseboard, make a mark at the intersection of the lines and where the corner of the room is.
  • Connect the marks with a line on the fillet and trim with a sharp knife. The cut should go inside the fillet.
  • We check the joint at a corner, trim, if necessary, and glue the skirting board in place.

How to cut a skirting board with a skirting tool

The baseboard is a three-sided box made of wood, metal or plastic, with 90 and 45 degree angled slots made in its two vertical sides (see skirting boards). The junction between the wall and the ceiling: how to choose the right ceiling plinth). With the help of a wire cutter is easy to trim ceiling skirting boards to fit straight sections and design the correct right angles.

Inner angles

In a standard rectangular room, all corners are interior. The fitting of the skirting boards starts with them, so that you can disregard the length adjustment as well.

Tip. Before you cut the ceiling skirting, decide which side it will be adjacent to the wall, and which side it will be adjacent to the ceiling. This depends on the relief of the product and its profile. If the baseboard is not symmetrical, then its wider shelf is attached to the wall.

The correct installation of the ceiling skirting

  • To cut the left corner, place the skirting board in the mortar so that its longest part is on your left and the one you will cut is in the mortar itself, with a slight 45-degree angle to the right slit. Styrofoam Ceiling Cornices: cheap, angry, and also very beautiful).
  • The part of the baseboard that will be glued to the ceiling, press it to the bottom of the wood cutter, and the one to the wall. press it to the side wall closest to you.
  • Holding the baseboard firmly in this position, cut a corner through the slit with a hacksaw or construction knife.

How to cut a ceiling plinth to the left side of the inside corner

Having cut the corners of both skirting boards, press them into the corner without glue yet, to make sure that the cuts match. If this is not the case, trim them with a construction knife. After that, the skirting boards can be glued.

Tip. Experienced finishers advise beginners to first fit and glue baseboards in all corners, and then already glue straight sections between them.

Outer corners

External corners are found in rooms with internal overhangs or niches (see scrapbooking). How to make the corner of a ceiling plinth: tips from the masters). If you do not know how to cut the ceiling skirting boards in this case, then we hasten to reassure you. This is done exactly as in the previous case, the only difference is that the left-hand skirting board is cut through the left-hand not the right-hand slot in the jigsaw. That is, at a different angle.

As a result, the part of the skirting board that will be adjacent to the ceiling, will be longer.

Do the same with the right skirting board: put it in the molding from the right, pressing it to the bottom and side wall, and cut it through the right slit.

Attention! When gluing the skirting board to the outer corner, make sure that the edge of its bottom part coincides exactly with the edge of the wall corner. If you have any questions, please watch the detailed video at the end of the article.

How to do without a joiner?

For a perfectly smooth fit of the two corners at the junction of the ceiling mouldings can be cut blanks, not placing them in the jigsaw, and making a mark directly on the ceiling. To determine and place a mark for the inside corner, the length of the ceiling moulding is measured starting from that corner. In order to perform the marking of the outer corner it should be borne in mind that towards the room wide eaves will go out exactly the size of its width.

Consider in detail how to saw a skirting board without the use of a plier

  • On the right side of the angle to press the cornice to the ceiling surface and to draw an additional straight line, placing it along the outside of the workpiece.
  • Where the mowing lines can cross, that point and draw a straight line from that point to the bottom corner of the baseboard. This is the way to get a marking that will be used for sawing the baseboard at the desired angle.
  • The next step, when both corners will be cut, they are folded towards each other and check the quality of the resulting junction. If any errors are found, clean them up by using sandpaper and also a file.
  • After both pieces are a perfect fit, the eaves need to be cut to the required length and glued to the wall. The trimming is not made before the moment of the perfect race of the cuts of the corner joints. When fitting it is necessary to know that in order to decorate stretch ceilings, ceiling skirting is not fixed to the ceiling, but only mounted on the wall.

To trim the skirting board to join it in the inner corner of the room marking is done as follows:

  • Put the two skirting boards together and if the joint is inaccurate, one side must be trimmed again; after a perfectly made joint, the skirting boards can be mounted to the wall.

When installing a wooden or polyurethane ceiling moulding, correct inaccuracies in the joints with a file. To adjust the cut edges of the foam plastic or polystyrene parts, you can correct the imperfections with a sharp knife. Such a method of trimming the ceiling cornice is convenient in those homes where the outer or inner corner is not aligned exactly under 90 °, and has a size, for example, 87 ° or 94 °. Using a jointer in this case will be ineffective.

How to mask the joints

With any neat work, there are flaws, and installing a ceiling plinth is no exception, especially if you are doing it for the first time, and have no idea how to accurately cut the ceiling plinths. Flaws and imperfections can be removed this way:

  • Apply glue to the joints to fix the skirting boards.
  • As soon as the glue dries on the joints. it is enough to wipe it off with a clean rag.
  • As for gaps in the ceiling area, they are plugged with putty and painted with paint. This should be done carefully with a rubber spatula.
  • If you have white sealant at home, you can use it to seal the gaps, then you do not have to paint the joints.


Ceiling plinth performs not only a decorative function, visually separating the walls from the ceiling, but can also hide joints of various finishing materials of the ceiling and walls. Not every interior design involves the use of a skirting board, but most often the overall appearance of the room seems incomplete without it. There is nothing complicated about fixing this element of the moldings, almost all types of skirting boards are attached to the glue. But the question of how to properly cut the ceiling plinth in the corners of the premises, can puzzle many. After all, even in the simplest rooms, there are interior corners where ceiling plinth strips must be docked accurately and beautifully. And in a more complex configuration of the room will have to join the skirting boards, performing an external corner. In this article we will consider different options on how to cut the ceiling moldings with or without the help of hand tools.

First, you should deal with the question of what to cut the ceiling plinth, the answer to this depends on the material from which the fillet is made. At the moment, ceiling skirting boards are sold in polyvinyl chloride (PVC), polystyrene (polystyrene foam), polyurethane and wood.

PVC ceiling skirting boards are the cheapest. Dents and creases easily form on them, which cannot be repaired, so the product has to be discarded. Also their disadvantage is the electrostatic nature of the ability to attract dust. They can be cut with a sharp construction knife or a hacksaw.

Skirting boards made of expanded polystyrene also belong to the cheapest ones. This material is very fragile, when processed easily crumbles, so cut the polystyrene foam must be a sharp knife or hacksaw for metal, not making too much pressure.

Ceiling skirting boards made of extruded polystyrene are slightly more expensive than polystyrene boards, they are denser and harder to cut. However, they are less crumbly, so they are easier and easier to work with. Can be cut with a construction knife and a metal saw.

Polyurethane ceiling plinths are the most expensive at the moment. They are strong, flexible and moisture resistant, easy to cut with a construction knife and do not crumble. A disadvantage of polyurethane skirting boards is their dependence on temperature differences. For example, over a gas stove, a polyurethane skirting board will acquire residual deformations and begin to crack slightly. If you try to treat or trim such a skirting, it may warp or deform in another way.

Wooden ceiling mouldings are thick and heavy products which can only be trimmed using a hacksaw, preferably with fine, dense prongs. A metal blade can also be used.

Before proceeding to the listing of ways, how to properly cut a ceiling plinth, I would like to note that there is a possibility not to cut the plinth with special precision. Special corner elements are available for sale, into which the edges of the skirting board are inserted. In this case it is enough to trim the skirting board at an angle of 90. And the corner element will hide all the imperfections. But this method is not always used, because the size of the corner elements is somewhat larger than the skirting boards themselves, so the corners in the room will stand out against the general background. Sometimes it can look scuffy. Nevertheless, if the design of the room allows the use of angular elements for ceiling plinths, it makes sense to use them. The following instructions will be useful to those who still decided to accurately cut the baseboards to a given angle.

How to cut the corner of the ceiling baseboard with a wire cutter

The chisel is a simple carpentry tool that allows you to cut a piece at the desired angle. The most common is a tray of plastic, wood or metal with vertical slots for cutting at 90 and 45 degree angles. There are also more complex designs of the saw for cutting at angles of 90, 60 and 45 degrees. For more professional work, a mortiser with a pivoting mechanism is used, where the hacksaw can be attached at any angle to the workpiece.

How to cut a ceiling skirting board with a jig saw:

  • Then put the skirting board on the ceiling, measuring the required length.
  • Then place the baseboard plinth in the jigsaw so that the position coincides with the position of the plinth on the ceiling.
  • The baseboard plinth has to be pressed against the far wall.
  • Hold the skirting board with the left hand.
  • We choose a sawing position with a 45 degree angle, with the saw blade as close as possible to the left hand.
  • Cut the skirting without exerting too much pressure on the saw.
  • The next step is trimming the skirting boards. Also set it against the far wall of the baseboard cutter.
  • Press down and hold with the right hand.
  • We choose a position for the hacksaw when the angle is 45 degrees and the handle of the hacksaw is close to the right hand.
  • Trimming the skirting boards.

Next, join the cut skirting boards and check the accuracy of the cut. For a more accurate orientation it is also said that in order to make an inside corner it is necessary to start cutting from the front part of the skirting board. Wooden skirting boards, after cutting, may have to be adjusted with a file as well.

How to cut the ceiling skirting board with a power plier outer corner:

  • Not to make a mistake with the size, it is better to start with the marking of the inner corner, and then already cut the outer corner. Otherwise it is possible that the plank may not be long enough.
  • It is necessary to attach the strip to the ceiling and mark out the dimensions.
  • Install the ceiling plinth trim and press it to the nearest wall.
  • Hold it with your left hand and use your left hand to hold the hacksaw at a 45 degree angle with the handle close to your left hand.
  • Cut the workpiece.
  • Position the counterblade against the nearest wall, hold it with the right hand.
  • Set the hacksaw at a 45 degree angle with the handle close to the right hand.
  • Cut the workpiece and join the corner.

Trimming the workpiece with the jigsaw is suitable only if the angle between the walls is exactly 90 degrees. If, however, accuracy leaves much to be desired, we must use other methods.

How to cut a ceiling plinth corner with the help of a marking on the ceiling

The marking of the skirting board on the ceiling also allows you to evenly and accurately cut a corner. The only disadvantage of this method is that it is difficult and inconvenient to keep the baseboard on weight in the process of cutting. Otherwise, you can cut even more precisely than with other methods. When applying the skirting board to the place of installation, all wall imperfections and corner deviations are taken into account at once.

Cuts the corner of the ceiling plinth:

  • The intersection point of the marked lines will be the mark at which the skirting must be cut.
  • Again, we enclose each slat in turn and mark the cut point on them.
  • Guide the fishing line from this point to the other edge of the baseboard.

We cut the skirting boards along the planned lines, dock them and attach them to the place of installation. Please note that this method is more convenient for cutting inner corners.

How to cut a ceiling skirting board using a jigsaw template

Something reminiscent of a wire cutter can be made by marking the necessary angles of cut on paper, cardboard or wood. You need to draw two parallel mowing lines, determine the center, and then set off the necessary angles using a protractor. The advantage of this method is that you can defer any angle, including greater than 90 degrees. Of course, before you cut the corners of the ceiling plinth, you must first check the angle between the walls with a corner and measure with a protractor.

The method of cutting the ceiling plinth with the drawn jig is exactly the same as with the jig itself. We press the baseboard plank to one of the parallel lines, then set the hacksaw at the desired angle, which is already marked, and cut off.

Improvised tray-stool with their own hands

It is also not very difficult to make a jig with your own hands.

We need three wooden planks or boards, which should be chipped into a U-shaped box. Then the necessary angles are marked on the walls of the box, and the cut is made with a hacksaw. The end result should be a wooden chair, in which the grooves are cut out.

Combination of improvised chisel and template with marked lines. For ease of cutting you must construct something in which it will be convenient to hold the ceiling plinth plank, because keeping it by weight is difficult. It is enough to chip a corner from two wooden slats or boards. On the paper you need to draw a mowing line with angles for cutting at 45 degrees or any other. Then we put a piece of baseboard to the corner, press it by hand, as described in the technology of using a wire cutter, a piece of paper with a template moves under the edge where we are going to perform a cut, and cut off. In the process of cutting we are guided by the line drawn on the paper.

Anything can be used as an improvised jigsaw, anything. That we form a corner. For example, a table placed against the wall.

Important! Pay attention to the rule of measurement for trimming ceiling plinth. To mark an inside corner, you must measure the length directly from the corner itself. To outline the outer corner, it is necessary to orientate that the baseboard will protrude into the depth of the room at a distance equal to its width.

Do not fix the ceiling skirting boards before you cut the counter batten and tried on their location. Only after the two mating strips are perfectly aligned in the corner, you can begin to mount them to the ceiling. Small imperfections can be finished with a file or file in the case of wooden and polyurethane skirting boards. For fitting the foam products it is necessary to wield a sharp knife.

If suddenly, even after fitting the skirting boards between them remains a small gap, do not despair, it can be sealed with putty. It is not difficult to cut the skirting boards yourself. But not to spoil many products, it is better to train on small workpieces beforehand.

Cutting method with a wire cutter

The most popular fixing option using household tools. The woodpencil is a well-known helper of the carpenter, helping to make a cut at the right angle. Usually it is a tray, wooden or plastic, which has vertical slots for the blade at angles of 45 and 90 degrees. How to cut the corners of ceiling plinths with a power plough?

To begin with, you should attach the material to the ceiling, set its plank in the jig. In doing so, the tool should coincide with the position of the product. Holding the baseboard with the left hand, choose a position for the cutting tool (hacksaw) at an angle of 45 degrees. Cut the material without excessive pressure. After that, they cut a responsive plank, install it to the far wall of the mash.

Holding the working material with the right hand, select the position of the hacksaw at 45 degrees and cut.

Materials and features of their cutting

The answer to the question of how to cut a ceiling plinth, depends on what material it is made of. Cutting is different because baguettes have different densities. That is why the first thing to consider is the most popular materials, and at the same time, the peculiarities of their cutting.


Such products have the lowest price, because the material is very resistant to mechanical impacts. Styrofoam can be easily scratched or damaged by an accidental blow. Advantages. minimum weight, which simplifies gluing, easy processing, the ability to paint in any color.

This foam material consists of small particles, which are quite easily separated from each other. However, they are the main disadvantage of such baguettes. They require very sharp tools. Otherwise the skirting boards could crumble and therefore will be unsuitable for installation. This is true for both angled and straight cuts.


This contender is more expensive, but it does not differ from the first candidate very much, since it is a “relative” of Styrofoam: it is produced from expanded polystyrene. This material also consists of small granule bubbles, but they fit together more densely. But Styrofoam will not tolerate a blade that is not too sharp, it will also crumble. Therefore, the master needs to prepare no less sharp implements.

The main advantage of foam and polystyrene foam is their softness, which allows you to avoid gaps, tightly pressed pieces to each other and to the corners.

Extruded polystyrene foam

EPPS is produced from the same raw materials as conventional polystyrene foam, but in this case using a different, more sophisticated technology. Conventional PVC is made with steam, which is run through microgranules.

To obtain the extruded polystyrene foam, the particles are mixed at a high temperature and the same pressure, and then in the raw material is added blowing agent. The size of the granules in this material is much smaller (maximum 0,2 mm), as a result it is less crumbly and more resistant. Very sharp tool for its cutting is not required, but bluntness of the cutting edge is also not welcome.

Polyvinyl chloride

Plastic skirting boards (PVC). another type of ceiling products. They are usually bought for finishing of bathrooms. If we consider the topic “How to cut a ceiling plinth”, in this case they are exceptions, because for their docking use special, ready-made corners.

In general, these baguettes can be cut with a box cutter, a metal hacksaw, or a sharp kitchen tool. Since PVC products do not restore their shape due to lack of elasticity, it is not recommended to put a lot of pressure on them when cutting.


This is another representative of polymer products. It is characterized by high density and lack of disadvantages of previous competitors. It is easy to cut, so the tool must be sharp, but there are no maximum requirements for its sharpening. Polyurethane skirting boards do not crumble, do not deform, and honorably endure almost any pressure.


This traditional material is cut with the usual carpentry tools: for example, a jigsaw, hand or electric. Work the places of the cut with sandpaper or a file. Since such products are more expensive than other baseboards, care is required when working. A serious mistake can be made easily, but there is no way to correct it. The consequence of carelessness will be the purchase of a new baguette.

The ideal tool for cutting wood would be an electric mitre saw. Its biggest disadvantage is its high price, especially for quality models. On the other hand, buyers have the opportunity to find an inexpensive tool that will do the job decently.
