How to cut a 45 degree ceiling plinth?

The ceiling plinth, or fillet, is the subject of the final decorative decoration of the room, separating the ceiling and the wall. In addition to the decorative function, it also has a completely functional value, hiding the joints of the wallpaper and the ceiling. It is simply impossible to decorate the edges of the wallpaper in any other way, and, as you know, they move away precisely along the edges. Corner decoration can be a problem when using fillets. Mistakes can lead to waste of material, and such incorrectly cut skirting boards look unattractive. In this article, we will look at simple ways to optimally file a ceiling plinth at an angle of 45 degrees.

To cut the ceiling plinth at an angle of 45 degrees, you need to decide on the sides. The main mistake is the incorrect definition of the fillet sides. A proven way to determine the correct side is to apply material in place. So it becomes clear how you need to cut the skirting board. This operation, despite the apparent simplicity, is very laborious, since after trying on the plinth with it you have to go down to the place where the sawing will be done. Most often, in order to avoid deformation or damage to the skirting board, especially if it is made of foam or similar material, you have to cut it on the floor.

The joints of two skirting boards in the corners should look aesthetically pleasing, so you need to cut or saw them off as carefully as possible. A hacksaw for metal works well for this. In some cases, a sharp knife. If it was washed down correctly, small imperfections can be eliminated with putty or sealant.

Starting the decoration of the room with ceiling plinths, it is necessary to prepare the appropriate tools:

• stationery knife for foam baseboards;
• hacksaw for metal;
• roulette;
• carpentry or simple school square;
• miter box;
• pencil;
• a stepladder that is stable and sufficient in height.

It is necessary to free up space on the floor in order to make it convenient to cut the skirting boards. It is on the floor that it is best to place a miter box, the length of a table or a portable workbench is not enough to securely place the plinth to be sawn off.

In addition to cutting with a carpenter's miter box, in which the angles are clearly defined (90, 45, sometimes 60 degrees), there are other methods. More expensive is the use of a rotary miter box or a rotary circular saw. Cutting a corner with a tool where it can be adjusted and fairly easy to set is not difficult. Cutting is done either by hand or using a circular cut.

In order to grind the fillet at home, you can do with a more budgetary option by preparing a homemade plywood miter box. It is important to clearly measure the corners and make cuts, along which the plinth will be sawn off in the future.

In order not to confuse the sides of the plinth and cut it correctly, at first it is better to apply it together with the miter box to the ceiling, gradually a skill will be developed and it will be possible to do without multiple movements up and down.

You can also prepare a kind of miter box layout on cardboard, while the plinth to be sawn off will have to be applied to the layout and marked with a pencil. In order to cut the required corner, it is better to move it to a more convenient place, in addition, it is important not to spoil the layout.

There are ways to cut corners without a miter box. This is all the more important because the angles are not always perfect, and the standard 45 degree angle may turn out to be wrong. In order to make a corner in this way, it is necessary to attach a piece of skirting board directly to the ceiling exactly as it will be mounted. With a pencil, it is necessary to mark the width of the fillet on the ceiling. Attaching the skirting board to the other side of the corner, you also need to mark its width on the ceiling.

It is necessary to cut off from the edge to the marked point, it is important to remember the sides with which the plinth will adhere to the wall and ceiling, in no case should they be confused. Small flaws can be corrected during the installation process, cut with a clerical knife, if the baseboard material allows it. With wooden fillets, everything is much more complicated, there a knife will not help.

In-situ measurements allow cutting both inner and outer corners without great losses, although the latter are not common, yet their finish is significantly different.
