How to cut a corner of a ceiling plinth

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

Which skirting board should you choose?

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

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

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

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

Cutting corners without a miter box

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

Manual template preparation

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

  • Protractor;
  • Pencil;
  • Cardboard.

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

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

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

How to get the correct angle

Most of the problems when working with skirting boards arise in the design of corners. Since the surface of the products is complex, it will not be possible to simply cut off at the desired angle: it is also necessary to cut so that they dock and, preferably, without large gaps. There are actually several ways to make the corner of your skirting board perfect (or almost).

What and how to cut

Working with skirting boards made from different materials means using different cutting tools. When working with a wooden skirting board, it is more convenient to work with a saw on wood. All others, including plastic ones, made of polystyrene and other polymers, are better cut with a blade for metal. The result is a smoother cut, less burr. Saws are usually used when working with a miter box.

Corner design looks attractive

When working with polystyrene skirting boards, they cut them with a good stationery knife without special devices. Its blade is quite thin and even, the cut is smooth, not wrinkled. If you work with a saw with polyurethane or polystyrene, do not press hard: you can wrinkle.

In general, to get used to the tool and material a little, take a piece and practice on it: cut, saw, trim. So there will be fewer problems when working.

What is it made of and what is it called

The very first skirting boards on the ceiling were made of plaster. They were cast in special molds and then installed on the ceiling with mortar. Such figured decorations were called fillets. Today you can rarely see them: they are expensive, and outwardly they are almost indistinguishable from the cheaper options. And the name is almost lost.

The most popular ceiling skirting boards are made of polyurethane or polystyrene. They are inexpensive, look great, easy to install, have a wide range of profiles and patterns. The width can be from 5 mm to 250 mm. They are used in almost any room, decorated in any style. The exception is wooden houses with a corresponding interior. Wooden products are most often used here. The style dictates its own conditions.

Cutting the corner with a miter box

Take a polyurethane skirting board designed for the left or right side of the corner. We lean it against the future installation site so that the end of the segment opposite from the corner is in the edge of the already glued molding. In the place where the lower edge of the ceiling plinth is in contact with the top of the corner of the wall, put a point with a pencil or stick a piece of insulating tape. We repeat these actions with the second segment.

  • We place the left blank in the miter box from left to right, pressing it to the edge closest to us. The corner vertex mark must match the leftmost slot in the same edge
  • We place the right blank from right to left, pressing it to the near edge. Corner apex mark. To the far right notch.
