How to cut down a ceiling plinth under 45

Methods for cutting corners on a ceiling plinth

There are three main methods for cutting corners on skirting boards:

• using a miter box;
• using a drawing on the table;
• using the markings on the ceiling.

Of course, you can add another method to this classification. “approximately”. But despite the fact that it is used quite often, this practice almost does not allow achieving a high-quality joint of elements (read: “How to dock a ceiling plinth. Options”).

External ceiling

We already cut the ceiling corners on the inside of the fixture. Having inserted the left plinth into the miter box, we cut off the left outer corner. Substitute Right. Right Outer Edge Mode.

The cut ends, for a snug fit to each other, must be processed with a file or sandpaper, after which the profile can be installed in place. To catch all the nuances of installation, be sure to watch the video on how to cut the ceiling plinth, the video instruction demonstrates how and where to apply the profile in order to make the right cut.

Buying a miter box for cutting at one time is completely impractical, so you can make the device yourself. To do this, you will need a rectangular base part, made of plywood or chipboard, for the sides. bars, all elements are aligned, the bars are installed at the edges, their parallelism is checked, the parts are fixed on self-tapping screws. Next, the angles are marked along the protractor, an angle of 45º can be measured using a square sheet folded diagonally.

The 60º angle is also very easy to make. It is known from the school course that the angles in an equilateral triangle are 60 degrees, draw a triangle with the same sides on paper, cut it out, this will be the template along which the cuts are made.

Before sawing down the ceiling plinth, check the corners, if they are 90g, use a miter box

In order to cut it off, it is necessary to put the plinth into the miter box from the side from which the element will be fixed to the ceiling. Thus, the ceiling molding is applied to the near wall of the miter box. After that, along the gutter, which has a slope of 45 degrees, the skirting board itself is cut.

The fillet is applied with the lower part to the top of the miter box. Thus, we will see the element exactly in the same perspective in which it is attached to the ceiling. Do not forget that the lower point of the cut will border on the corner of the wall, that is, it will be the extreme point of the profile.

In order to cut the left outer corner skirting board, the hacksaw is placed from left to right, and for the right skirting board, on the contrary, from right to left.

And what to do to cut the inner corner of the left skirting board? In this case, the lower extreme point of the element will protrude, so the left fillet is cut from right to left, and the right one. from left to right. Thanks to this, we get the inner corner.

This is a special tool that looks like a slotted tray. The grooves are designed for precise cutting of corners on bars, battens and other elements. As a standard, the miter box has stencils of such angles as 45, 60, 67.5, 90 degrees.

Cutting corners using a drawing on the table

But how to cut down a ceiling plinth if you don’t have a miter box in your arsenal? You can do it in a different way. To do this, we need a drawing on the table that will simulate a stencil with corners.

First, two mowing lines are drawn in parallel on the surface, the distance between which is equal to the inner part of the miter’s gutter, namely 8.5 cm. Now, using these lines, they make a square in which two diagonals are drawn. This gives us 45 degree guide angles.

The first way is with a miter box

Professional miter box with swivel hacksaw The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool is the oldest and simplest carpenter’s tool for cutting wood pieces at 90 ° and 45 ° angles. There are types of such a device for professional work, with a rotary mechanism, in which the cutting tool can be rotated and fixed in any position. How to cut the ceiling plinth correctly Ceiling corners are divided into internal and external, the method of joining them is slightly different.

If necessary, you can make a miter box with your own hands. To do this, you need three trims from plywood or boards of the same size. First, they are applied in the form of an inverted letter “P” and the corners are marked. Then, according to the marking, slots are cut out for a hacksaw almost to the very bottom, and the boards are twisted.

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.

Fundamental rules

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 its seeming 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 baseboard, especially if it is made of foam or similar material, you have to cut it on the floor.

Then all this must be lifted back to the ceiling for final fitting and installation, the same steps are done with another segment.

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.

Required tools

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 stable and high enough stepladder.

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.

The ways

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. 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.

The purchase of such equipment for finishing one room, bathroom or even an apartment is hardly justified, another thing is professional activity, in this case, of course, it is better not to save.

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 repeated 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.

There will be two intersecting line segments. Then again you need to attach the pieces of the plinth to the ceiling and mark the same point on them.

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.
