How to cut the outside corner of a ceiling plinth

How to cut a ceiling skirting board: work with or without a tool

Every repair requires attention to the smallest detail. The quality of the finishing depends on the appearance and general perception of the room. To a greater extent, this applies to the ceilings, which in most cases are not perfect, so to hide all the imperfections (and walls), many owners use ceiling skirting boards, which give the room completeness. If the installation of baguettes in straight sections does not cause particular difficulties, the joints of elements in the corners require maximum accuracy. Therefore, many owners who are planning, or have already begun repairs, are interested in how to cut the ceiling plinth, what tools can be used for this stage of the work.

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 density. Therefore, the first thing to consider is the most popular materials, and at the same time the peculiarities of their cutting.


These products have the lowest price, because the material is very unstable to mechanical influences. Styrofoam is easy to scratch, damage by accidental impact. Pros. minimum weight, which simplifies gluing, easy processing, the ability to paint in any color.

This foam material consists of small granules, which can be separated from each other quite easily. However, they are the main disadvantage of such baguettes. They require a very sharp tool. Otherwise, the plinth can crumble, so it will be unsuitable for installation. This is true for both angular and straight cuts.


This contender is more expensive, but it is not very different from the first candidate, because it is a “relative” of Styrofoam: it is produced from expanded polystyrene. This material also consists of small granule bubbles, but they adhere to each other more densely. But Styrofoam will not tolerate a blade that is not too sharp, it will also crumble. Therefore, the master needs to prepare an equally sharp instrument.

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

Extruded polystyrene foam

EPPS is made from the same raw materials as conventional polystyrene, but in this case uses a different, more sophisticated technology. Conventional EPS is made with steam, which is passed through the microgranules.

To obtain the extruded polystyrene foam, the particles are mixed at high temperature and the same pressure, and then foaming agent is added to the raw material. The size of granules in this material is much smaller (maximum 0.2 mm), as a result it is less crumbly and more durable. Very sharp tools are not required to cut it, but bluntness of the cutting edge is also not welcome.

Polyvinyl chloride

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

Generally speaking, these baguettes can be cut with a box cutter, a metal hacksaw or a sharp kitchen tool. As PVC products do not reshape due to lack of elasticity, it is not recommended to apply too much pressure when cutting.


This is another representative of polymer products. It is characterized by high density and the absence of the 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 baseboards do not crumble, do not warp, and can withstand almost any pressure with honor.

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

The ideal tool for cutting wooden blanks will be an electric trimmer saw. Its biggest disadvantage is the high price, especially of high-quality models. On the other hand, buyers have the opportunity to find an inexpensive tool that will do a decent job.

Chisel for baseboards: basic rules for use

Everyone will be able to understand how to properly cut the corners of the ceiling plinth. For the process to go smoothly, you should familiarize yourself in advance with the main ways to create beautiful and even workpieces.

The main rule of work. the observance of the slope of the corners. If the baseboard is fixed on the right, the corner will be cut from the left side, and vice versa.

Cutting with a power plier: inside corner

To get the right inner corner, it is easiest to use a professional tool. Of course, such work can be done without a chisel, but in that case you will need to make more effort. Consider the sequence of operations for cutting the inside corner with a wire cutter.

The first thing to do is to determine the distance from the corner on the outside to the nearest wall. Next, it is necessary to mark the skirting board, thus preparing it for cutting. On the outer side of the batten, you need to draw a line for the trimmer along the length of the measurement. It is worth bearing in mind that in this case the top of the trim must protrude slightly.

After that, you can start trimming. To do this, the ceiling plinth is placed in the cutting tool and pressed firmly against the wall. After trimming the first piece, you can begin processing the counter element.

Other ways

With good eye and hand accuracy, you can use a homemade template, which 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 lines 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, and impose on the drawing and align a hacksaw with the marking of the layout.

Special accessories for the joint Installing ceiling skirting boards, 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 carpentry work, 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.

The connection of a skirting board with decorative corners

If the walls are perfectly prepared, and the outer and inner corners are equal to 90°, it is possible to use special decorative elements to join the skirting boards. The advantages of such a method:

  • easy installation: no need to “chisel”, improving the technique of trimming parts of the skirting boards;
  • saving time: to dock the elements you just need to cut them at right angles and attach the decorative part.

The decorative parts themselves for docking the fillets are designed to:

This method of connection is the only option in the case of installation of a plastic baseboard, which trimming without gaps is impossible to perform.

The tools you use

Depending on the material of manufacture, different tools are used for the fitting of baseboards: when working with wooden baseboards, wood hacksaws are used, and when working with plastic or polyurethane baseboards it is better to use a hacksaw for metal. Elements of foam decor are easy to cut with a regular, sharp office knife. In most cases, a plier is used to cut the skirting board evenly at a certain angle. If you use a hacksaw for metal, then you should not press hard, because the cut may not turn out even, with burrs, and the material can crumple and lead to disrepair. Polystyrene and polyurethane skirting boards require careful handling.

If there is no experience with such tools, as well as elements of the decor, it is better to take a small piece of finishing material and practice with different force of pressure, which will later help in solving the problem.

Not every interior design requires the use of a skirting board, but most often the overall appearance of the room seems incomplete without it. In fixing this element. the baseboard. there is nothing complicated, almost all types of baseboards 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.

corner, ceiling, plinth

After all, even in the simplest room, there are interior corners where the ceiling skirting boards need to be accurately and beautifully joined. And in more complex room configurations have to join the skirting boards, making the outer corner. In this article we will consider different options on how to cut the ceiling plinth with or without the help of hand tools.

To begin with, we should deal with the question of what to cut the ceiling plinth, the answer depends on the material from which the fillet is made. At the moment we sell ceiling skirting boards made of polyvinyl chloride (PVC), polystyrene foam (foam plastic), polyurethane and wood.

PVC skirting boards are the cheapest.

They are easy to form dents and creases, which can not be eliminated, so the product has to be thrown away. Also their disadvantage is electrostatic. the ability to attract dust. They can be cut with a sharp construction knife or a hacksaw.

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

Extruded polystyrene skirting boards are slightly more expensive, denser and harder to cut than expanded polystyrene boards. However, they are less crumbly, so they are easier and more convenient to work with. Can be cut with a construction knife and a metal hacksaw.

Polyurethane ceiling plinths are the most expensive at the moment. They are strong, flexible and water-resistant, can be easily 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 trim or trim such a skirting board, it may warp or deform in other ways.

Wooden ceiling skirting boards are dense, heavy items that can only be trimmed with a hacksaw, preferably with fine, frequent cogs. It is also possible to use a canvas on metal.

Before proceeding to the list 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 particular precision.

corner, ceiling, plinth

On sale, there are special corner elements, in which the edges of the skirting are inserted. In this case, the plank of the plinth is enough to trim at an angle of 90 °, and the corner element will hide all the flaws. But this method is not always used, as the size of 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 clumsy. Nevertheless, if the design of the room allows the use of corner elements for ceiling skirting boards, it makes sense to use them. The following instructions will be useful to those who still decided to precisely cut the skirting boards to a given angle.

The second way. without additional tools

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

The end result will be an even angle of 45 °, if you draw a trimmer line from the point of intersection to the edge of the part. Note that the above method of marking works only with perfectly straight corners.

Cutting a corner with a false chisel

The third method of trimming the corner of the baseboard is not quite usual. using a kind of false chisel. You can make such a “tool” in two ways.

The first is to draw a jig. To do this, you can use plain thick paper or cardboard: draw two parallel lines on the sheet and, using a protractor or simple angle piece, set off the angles with the required degree. The corner is cut in much the same way as with the joiner’s chair: place the skirting board against the “tool”, make the necessary marks and follow them with the notches.

The second way. to make a prototype of a crosscut out of three wooden boards: connect them in the form of an oblong letter “U” and make notches in 45 and 90 degrees. To mark the corners you can use the same protractor.

Wooden plank plinth

When you cut the corners of the skirting boards without a notcher, it is very important not to miscalculate the length of the strip and directly to the degree of notch. To avoid mistakes, at first it is better to cut blanks 10 cm longer, then try on the 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 perfect 90-degree corners. you still can’t do without adjusting the products.

Tip. Fix the plinth trim to the ceiling only after adjusting to her corner of the next baseboard blanks. It is better to try on the table, not under the ceiling itself, as it takes more time, but the cut lines will be neater and tidier.

Thus, we have several ways of trimming ceiling plinths at once: with the help of a joiner’s chair, without a chair, using a kind of false chair. Whatever variant of execution of the corners you have not chosen, it is important to do everything accurately and precisely. only then you will get a really effective tool for the final design of the ceiling, thereby making the interior of your bathroom aesthetically complete.
