How to cut corners of a wide skirting board

How to cut the corner of the baseboard with a homemade plinth cutter

A simple way to understand how to cut corners on the ceiling plinth. video or step by step instructions. You do not need to buy the tool in a professional store, you can use a homemade device. It is even possible to make a jigsaw out of paper.

For those who do not know how to cut a corner on the ceiling plinth, the video clearly demonstrates all the steps.

Gap-masking products are fastened so that they fit snugly to both the wall and the ceiling. The element has a special configuration, but to join its fragments, you must first cut the material

Baseboards are not cut at 90 degrees, but at 45 degrees. Such a solution then allows you to correctly align the baguette on both the outer and inner parts. It is possible to buy models with a pre-cut of this type. In this case, the user has to cut the elements only at right angles. But the model is more expensive and does not completely exclude preparatory work.

In practice, it is quite easy to cut the ceiling plinth at a 45 degree angle. Most often a special device is used for this. a plier, but you can also do with other means.

Types of ceiling and floor plinths, choice of tools

Installation of baguettes and baseboards is no less important stage of repair than any other. And trimming corners here is the most difficult. It is important to choose the right tool for the job and the most appropriate cutting method.

Ceiling plinth

Ceiling moldings, also known as moldings, fillets, borders or just plinths, are mostly used for finishing joints between the wall and ceiling, although sometimes they are used to cover inner corners, make decorative frames or panels, and decorate niches and architectural elements. There are several of the most popular materials for making ceiling moldings:

Plastic (PVC). Wide and rigid moldings are easier to cut with a metal hacksaw. If a more gentle tool is needed, a jigsaw is used.

Foam (polystyrene foam). It is very light and porous material, best cut with a sharp construction or office knife.

Wooden baguettes. Saw blades with a helical sharpening designed especially for baguettes are suitable for cutting. You can also use hand or electric jigsaws.

Skirting boards

Modern floor skirting can hardly be called a plank, closing the gap. This is a structural component that complements the design and accentuates the overall design. Baseboards are made of several materials:

Wooden can be made of solid wood or veneer. Plane or circular saws, jigsaws are used for trimming.

Plastic baseboards are dangerous competitors to traditional wood. Easy to install and cut with a regular metal saw.

Aluminum baseboards are the last word in interior design. Usually cut with an electric saw or a hand-held metal saw.

Only on the wooden skirting boards will have to do a corner trim. The rest are trimmed evenly and joined with special corners.

How to cut a skirting board inside corner

When we evaluate a new repair, we involuntarily direct our eyes, first of all, to the ceiling. No matter how mind-blowing the interior may be, its appreciation from crooked trim joints will fall dramatically. In this article, we will tell you the instructions about the ceiling skirting. how to make the angle of the joint perfectly flat.

Once you have finished finishing the walls and ceiling, you will unwittingly be left with ugly transitions between them. To do this, and use fillets at the transition point of the two materials. When installing them it is important to maintain the evenness and accuracy of the joints. Article on the topic: how to glue the ceiling plinth on the glue and putty.

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

The hacksaw usually appears in the form of a tray with vertical holes for the 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 an angle of 90 and 45 degrees. There are also kinds of such a device for professional work, with a swiveling mechanism, in which the cutting tool can be rotated and fixed in any position.

How to properly cut a ceiling plinth Ceiling corners can be divided into interior and exterior corners, the method of joining them is slightly different.

If necessary, you can make a plier with your own hands. To do this, you can use 3 scraps of plywood or boards of equal size. First of all, they must be arranged in the shape of an inverted “U” and the corners must be marked. Then, according to the markings, saw cuts are made almost all the way to the bottom, and the boards are twisted.

  • Make correct 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 tightly against the opposite wall of the jig saw. Hold it and press it with your left hand.
  • We put a hacksaw at an angle of 45 degrees in a special hole and cut the part.

When trimming 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 part.

  • Measure the length of the baseboard from the nearest wall to the outer corner, leave a fishing line on the underside with a pencil, marking the desired length. Take into account that the edge (its top part) should protrude slightly outside.
  • Move the skirting board into the jig and cut it.
  • The adjacent strip should also be measured with a reserve, and cut in a mirror reflection to the first detail.
corners, wide, skirting, board

Let’s try on the ceiling plinth. the joining of parts must be perfectly straight. If the result is not achieved and the joints are bulging. you can trim the edges with a regular knife to perfect the joint.

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

Method two. without additional tools

For the inner 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 result will be an even angle of 45 degrees if you run the fishing line from the point of intersection to the edge of the part. This way, how to cut the baseboard is available to everyone, without having special tools.

With a good eye and hand accuracy, you can use a homemade template that resembles an imitation of a chisel. To do this, take a thin board or thick 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 superimposed on the drawing and aligning the hacksaw with the layout markings.

Special accessories for joints 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 like beauty, but not joinery works, you can go another way. Choose a skirting board for your finishing, to which you will find in the store, a part matching the design, closing the joint. This method will save you time and effort.

How to cut the ceiling plinth and floor

The most difficult thing when installing ceiling and floor skirting boards is the design of the corner. Connect the strips in such places must be very carefully, otherwise the appearance of the decor will be hopelessly ruined. Of course, you can use quite an aesthetic special corner elements.

However, the docked natural way slats usually look more harmonious. And there’s no need to spend on extra parts. 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 of a variety of materials. foam, polyurethane foam. Plastic, wood. For their trimming, you can use the tools 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 cut with an ordinary metal saw.

Wood baseboard trimming is done with a usual hacksaw

For neat and maximally precise trimming of ceiling skirting boards usually a special tool is used. the plier. It represents a tray, knocked down from three boards. In its walls, there are 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. Buy a plier for ceiling plinths can be in a construction store.

Trimming the slats at a 45gr angle in the jigsaw

To cut the slats in the jigsaw, proceed as follows

corners, wide, skirting, board

Important: When trimming, remember that when framing an inner corner, the edge of the skirting boards 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

It is best to glue the corner before installing the skirting board on the walls

So we’ve figured out how to file a ceiling plinth (the video above will probably help someone to deal with this better) using a wire cutter. But what to do if you don’t have this tool handy?? It is actually possible to adjust the boards evenly without using it. There are two main ways to solve this problem: marking directly on the wall and making an imitation of a jig.

In the first case, the procedure is as follows:

How to cut a ceiling plinth without a chisel. Installing the first fishing line

Carry out the second fishing line, and mark the skirting board

Then cut the skirting at an angle using the mowing line you received.

Without the use of the tray mounted planks in the corner can be quite accurate

In order to saw a level corner you can also use the imitation of the jigsaw:

How to cut the corner of the ceiling plinth, using a simulated jigsaw

The improvised jigsaw is ready. Now it remains to attach the right ceiling element (the wrong side) on the right of the lower edge to the mowing line closest to you and cut. The same with the left plank (only it should be applied to the left).

Tip: You can cut the styrofoam strips with a knife. In doing so, however, sharpen it properly. Otherwise the material at the ends will simply crumble.

How to join the skirting boards if the angle is uneven

In urban apartments, and especially in older apartments, the walls are rarely flat. Therefore, the corners between them are often not straight. How to properly file the ceiling plinth in this case?

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

Uneven angle can be measured, using a trivet angle gauge

The resulting angle is divided into two, drawing the appropriate “notch” on plywood and trim 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 perform finishing joints. What to seal the joint in the corner? In case there remains a small gap, the sealing can be done with an ordinary putty in the color of the skirting board. The joints can also be passed with silicone sealant.

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

Important: Only the inner corner can be sealed with putty or sealant. The outer one should be trimmed as carefully as possible. Even a small gap will be impossible to clean unnoticed later on. Especially if the baseboard is wide.

Corner elements for ceiling skirting

The trimming of ceiling strips when using corner elements (special connectors) is also usually done in a jigsaw. How to file the skirting boards in this case? Everything is very simple. the cut is performed at right angles. In the absence of a tray, a normal protractor or an angle piece can be used. Corner elements (photo):

In case of corner elements the strips are trimmed at right angles

How to cut a skirting board properly

Skirting boards can be made of PVC. polyurethane. wood or wood-fibreboard. Just as in the case of the ceiling skirting boards to saw them, depending on the material with a regular saw (wood) or a hacksaw for metal (plastic).

You now know how to cut a ceiling plinth. Next, let’s see how to fit and trim a floor. How to use a planking mitre in this case? When trimming a floor skirting, the procedure is about the same as when figuring a ceiling skirting. For the inside corner:

The strip is inserted into the tray and pressed tightly

How to cut a skirting board in a corner if it is external:

How to cut a ceiling baseboard for outside and inside corners

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

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

How to trim a ceiling plinth properly

As correctly trimmed corners of the ceiling plinth look

Here is such a perfect ceiling plinth you can make with your own hands, if you follow these instructions.

For the manufacture of ceiling skirting boards are mainly used three materials, these are:

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

  • The most fragile and cheapest of them is foam plastic, although the strength on the ceiling is not very required.
  • The expanded polystyrene is much denser, can be easily cut with a knife and is of course more expensive.
  • The most difficult thing to process wood. In order for the corners of wooden baseboards to be perfect, you must use only a fine-toothed hacksaw, or even better a hacksaw for metal and a sanding sandpaper. Only then can an even corner be achieved

Trimming ceiling plinth with their own hands

Let’s review step by step how to cut the corners of the skirting boards (also called baseboard). In the vast majority of modern apartments, the corners of rooms and other rooms are 90°. The ceiling skirting should be trimmed at an angle of 45° or 90°. How to cut a ceiling plinth? To do this, a special tool is used, which is called a plough. In this tool are already made slots at an angle of 45 ° and 90 °. At first glance, the simple task of trimming a baseboard. But the fact is that he 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 inner corners with a wire cutter

To do this, you will need these tools:

  • Tack is placed on the bottom of the chair with the side that will be glued to the ceiling, and the underside is pressed against the wall of the chair, to its right slit.
  • Trimming the fillet is made with a hacksaw or sharp knife. Be careful not to cut too hard, so as not to deform the ceiling moulding and not to create chips.
  • In the same way we cut the adjacent corner of the skirting board, but already using the left slot on the jigsaw.
  • Then put these parts against the corner to check if there is a gap, you can trim them with a knife.

Tip.To avoid wasting material and to gain experience, practice on small pieces first.

How to properly lay the skirting board in the chair

Cut the outer corners with a mitre saw

  • Put the skirting board at the corner and mark the place on the skirting board where the outer corner begins with a pencil.
  • The baseboard is then laid in the mortar. The side that will be attached to the ceiling, laid on the bottom of the jig, and the other side pressed against the wall.The mark on the baseboard must be near the left-hand slot. Cut one edge.
  • Then cut the other half of the corner in the same way. Only the mark on the baseboard must be near the right slit.

Then put both parts on the corner and check if there is a gap. If everything is okay, you can glue the skirting board in place.

How to trim a ceiling plinth without a wood punch Trim the plinth for the inside corner

If you don’t have a wire cutter, you can do without it:

  • To do this we put the skirting board on the ceiling the way it should stand and run the fishing line along the ceiling.
  • Then we put the skirting board on the ceiling to the right of the corner and run the second fishing line.
  • Where the lines cross, make a mark on the skirting board and run a line from the mark to the bottom corner of the skirting board. This line will be the baseboard trim line.

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

Repeat the process for the left-hand corner. Cut straight along the lines with a sharp knife.Then place the skirting board on the corner and check to see if there is a gap. If there is a gap, we carefully trim the corners. Then the skirting board can be glued in place.

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

Marking for trimming the right-hand corner of the skirting board without the joiner

You can easily cut the skirting board for the outer corner without a plier:

  • To do this, we put the ceiling tack as it should stand to the right of the corner. Guide the fishing line with a pencil across the ceiling beyond the corner.
  • Then attach the fillet to the left of the corner and run a fishing line across the ceiling until it intersects with the first line.
  • On the fillet we do marks at the intersection of the lines and in the place where the corner of the room is.
  • Connect the marks with a line on the batten and cut with a sharp knife. The cut should go inward of the skirting board.
  • Check the joint at the corner, trim if necessary and glue the skirting board in place.

It should be noted that for 1 linear meter. Count the number of meters in your apartment, multiply by 100. This will be the amount you will save if you do this work with your hands.

How to evenly cut the corner of the ceiling plinth When we assess a new repair, we involuntarily pay attention,

How to evenly cut the corner of the ceiling plinth When we evaluate a new repair, we involuntarily stare,

Outer corners are less common than inner corners, and it’s much easier to trim them. We’ll now do everything the other way around than when we trimmed the interior.

Initially, we need to mark where our corner will begin, and to do this, we put the ceiling plinth to the wall with a marking: now the intersection point of the ceiling plinths will be the upper point of their adjacency, we mark it with a simple pencil and can begin to prepare the baseboard: to prepare the left side, we place the baseboard in the mortar so that the top of the molding pressed against the wall, the bottom. against the bottom, and the long edge was to the right. Again we cut along the slit with a mark of 45 degrees. The right-hand corner is prepared on the same principle, only the long edge of the cloth will be on the left.

In the case of rounded corners, no devices will not help us and we will have to do everything “by eye”.

The easiest way to form such a corner is to cut the skirting board into several parts of about 5 cm, trim all parts on both sides and check the joint in place, adjust if necessary, and glue them one by one. The pieces that will join the baseboard at the beginning and end of the rounding, on one side leave flat. It is important not to mix up fragments, so you can use a simple pencil to number them.

  • Do not worry that there may be gaps in the joints on the ceiling plinth, because they are easy to putty and after drying and painting are invisible. Exceptions are wood ceiling plinths. even a putty in tone can be noticeable.
  • Try on the cuts still on the floor, as it is easier than on the stepladder. Do not glue on the skirting boards until you are sure everything is trimmed correctly.
  • Do not worry that something does not work, and the cuts have to be adjusted a few times, have patience and everything will turn out.

As the saying goes, the eyes are afraid, but the hands do! If it is good to think through every movement, there is nothing terrible in the independent trimming of the baseboard, and a beautifully decorated room will please the eye of the owner and his guests.

Quality repair requires a careful and accurate attitude towards the details.

Completing the work with the ceiling, you need to decorate it well. for this purpose, ceiling plinths are used. As a rule, the installation slats does not cause any particular difficulties, to tinker with the corners. Consider in detail how to cut the ceiling plinth in the corners, talk about different ways, give useful recommendations

Ceiling plinths of any material can be cut using one of the following methods. They are suitable to all except plastic: these are finished using prefabricated corners.

Marking on the ceiling for trimming

To cut a plank to within millimeters will also help mark on the ceiling. Do it is not easy, because when trimming the skirting board will have to hold the weight. But, this is the most accurate way to adjust the angle on the ceiling plinth.

Having put a skirting board to the ceiling, you can see all the irregularities on the wall. The deviation of the angle is also visible and must be taken into account when trimming.

In order to make the trim correctly you need to:

  • Make a 90-degree cut on the workpiece.
  • Attach the workpiece to the ceiling, and outline its contours. In doing so, you need it to fit tightly to a perpendicular wall.
  • Then do the same on the adjacent wall, outlining the contour of the workpiece on the ceiling.
  • We put a point at the intersection of the lines, this will be the reference point by which the trimming of the corner of the baseboard will occur.
  • On each billet, alternately mark the cut point that coincides with the point on the ceiling.
  • From the point to the opposite side, at an angle run a fishing line, it will need to cut the baseboard.

Once the marking has been made, you can properly cut the skirting board, and try it on. It is worth noting that this method involves trimming from the inside of the workpiece.

Other Ways

With 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 thick plywood and draw a layout in the form of a horizontal rectangle. Using a protractor, mark 45° on the right and left sides of the rectangle. Draw a scythe line connecting the opposite edges. Now you can cut the ceiling plinth using this template. The actions are simple and similar to the description above in the first option. Only the ceiling parts must not be inserted, and impose on a drawing and align a hacksaw with the layout markings.

Special accessories for joining 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. We advise to pick up for their finishing skirting, to which you will find a matching figure in the store, closing the junction. This method will save time and effort.

How to cut the ceiling plinth at an angle?

Cutting the ceiling plinth with a wire cutter

Most often, for cutting at an angle, you use an uncomplicated carpentry tool, the plier. It is a construction of an aluminum, plastic or wooden tray with grooves that guide the blade of the hacksaw at certain angles to the axis of the tray.

How to cut corners with this tool?

  • Fix the skirting board in the tray in the same position as it will be installed on the ceiling. Align it on the side that will be pressed to the ceiling.
  • Use your free hand to cut along the guide groove. For wood, as already mentioned, a hacksaw is used. You can cut both Styrofoam and polystyrene with a metal saw. You can also cut Styrofoam or polystyrene skirting boards with a knife, but it has to be very sharp. Otherwise the material will crumble under the blade.
  • A wooden skirting board may need to be fitted with a file before fastening it to the wall. To fit softer skirting boards, use again a sharp knife.

Cutting corners is very easy; avoid, however, making too much effort. Styrofoam crumbles easily. Yes, and a wooden baseboard with too much enthusiasm is easy to split.

Cutting without a chisel

How to cut corners if you do not have a chisel at your disposal?

corners, wide, skirting, board

Method 1

One of the easiest solutions to make a counterpart of the chisel yourself.

  • We make a simple tray from three boards.
  • Cut it at a 45 degree angle. The angle can be marked with a protractor or a student’s angle piece.

The fishing line is very easy to make yourself. If you have a lot of corners to fit, this work will pay for itself

Method 2

You can get by with a tray and without a slot. Make a template corner of paper or cardboard (this is especially important if the angle is not exactly 90 degrees) and draw a fishing line on it, by which you will navigate.

Pin together at right angles planks (in this case it is easy to get by with two, not three).

  • Insert the skirting board for regular or stretch ceilings into the improvised tray in exactly the position in which it will be attached to the ceiling.
  • Align the tray with the edge of the template.
  • Cut the skirting board by referring to the scaffolding drawn on the template. Hold the knife or hacksaw strictly vertically.

Method 3

We need an improvised tray in this case too, but it can be absolutely any. You can simply use a table against the wall or the corner between the wall and the floor.

How to cut corners with such a strange tool?

  • Mark on the ceiling, the wall and the baseboard itself the future corners. These are the ends of the imaginary scythe line that will cut both planks of the baseboard.
  • Place the baseboard in the tray exactly as it will be attached to the ceiling in the bedroom or other room, and cut it off, guided by the drawn marks. A knife or a hacksaw blade again hold it strictly vertically.

How to cut a ceiling plinth in the corners with a minimal set of tools? Easy. You only need a pencil, a knife and an eye gauge

How to cut a skirting board in corners with a minimum of tools? Easy. Only a pencil, knife and straightedge are needed.


Ceiling plinth, like any other interior element, has its own characteristics, so before you buy it in a construction store, it is necessary to understand the materials used to make this element and what difficulties you will have to face during the work.

In the past, the ceiling plinth had another name. batten. Translated from German as “notch” or “groove. The material for making this decorative element was plaster, poured into a prepared mold. The frozen gypsum element was fixed on the ceiling surface with mortar. To date, gypsum ceiling plinth is very rare, its cost is high, and to mount it compared to modern counterparts is much more difficult.

Today, ceiling elements of several types of materials in many configurations are available. They are cheaper than gypsum ceiling elements, and they don’t look any worse. The cheapest versions are made of polyvinyl chloride (PVC). This material under slight mechanical effect is subject to deformation, formation of irrecoverable dents or bends leads to the complete replacement of the element. Besides, all PVC skirting boards are electrostatic and quickly become covered with dust.

Ceiling plinths of polyurethane and polystyrene are among the most demanded products. They won their popularity thanks to a reasonable price, a wide range of profile drawings, a variety of sizes (their width varies between 5-250 mm), and 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 changes in temperature, it is prone to cracking, especially if set over the kitchen stove.

The classic ceiling plinth is a product made of wood. Wooden elements, unlike the above types are not installed on the glue, for fixing screws are used. Skirting boards of this material decorate wooden homes or rooms, whose style dictates the use of wooden elements.
