How to trim the inner corner of a skirting board

How to make a corner of a ceiling plinth without a miter box

When pruning, you can sometimes do without a miter box. In some cases, this method is even more effective, since the miter box is designed for high evenness of the walls and ceiling. In fact, this is not always true.

  • The element is placed so that its edge rests against the joint of two walls. Mark the position with a pencil. The same is done with the skirting board on the opposite side.
  • At the junction of the wall and ceiling, the intersection points are connected and a diagonal is laid. Then it is marked on the product itself. This is the cut mark.
  • Cut with a blade along the marked mowing line. When docking, they are ideally combined. Using the same technology, you can cut the material for the outer corners.

Trim the inner corner of the product

First you need to attach the piece to the ceiling. This is done to measure the desired fillet length. After taking all measurements, you can install the skirting board in a previously prepared miter box. Try to install it so that the fillet location is exactly the same as on the ceiling. Hold the skirting board with your left hand and make sure that the fillet rests firmly against the farther side of the tool. The part that is intended to be attached to the ceiling should be on top, and the bottom should be firmly pressed against the bottom of the miter box.

The hacksaw blade should be turned at 45 degrees. Check if this is the case and start cropping. In this case, the hacksaw should be as close to the left hand as possible. Do not press hard on the tool when cutting.

After the part is cut off, proceed with the processing of the adjacent skirting board. It must be cut in the same way as the previous one, only on the contrary, in a “mirror image”.

Attention! When working with fillets made of PVC or expanded polystyrene, start work from the front of the product. Then the final result will be more accurate and aesthetic.

How to cut the skirting board in the inner corners: action plan step by step

Begin installing the skirting boards in one of the corners. If this is your first experience, choose the part of the room where something will stand.

Trimming skirting boards in corners requires some skill. But by making several joints yourself, you can beautifully design complex corners.

How to use a miter box to cut skirting boards? Place the device in front of you, preferably on a table, but also on the floor. It doesn’t matter which side to turn it, it is symmetrical. Insert the bar into the profile, turn it so that it will stand against the wall. When washing down a floor plinth in a miter box, the “wall” is the wall that is farther from you. Once again: press the plinth strip firmly against the back wall in the position in which it will be installed. Insert a hacksaw into the desired slots. You can start sawing.

How to properly cut a corner on a ceiling plinth

Most often, in dwellings, you have to deal with cutting at 45 degrees. You can cut corners on ceiling plinths in several different ways.

Ceiling skirting boards: cut with manual marking

If it is not possible to use a miter box in work, you must first properly prepare for work without it. It is best to practice on the fillet ceiling dummy. Skirting boards left over from previous work are also suitable.

Installing baseboard: caulking an inside corner

It should be noted that the method of trimming the skirting board without a miter box is more accurate, as it is possible to more accurately and correctly mark the angle for cutting. This way it is more convenient to cut the inner corners of the skirting boards. True, there are also disadvantages of manual trimming. a fillet made of wood or polyurethane is difficult to keep suspended during measurement work.

  • Let’s get to work. First of all, cut with a pre-prepared tool two special blanks at an angle of 90 degrees.
  • After this is done, you can apply the plank to the ceiling, resting its end against the wall, located perpendicular to the plinth. We take a pencil and draw a mowing line right on the ceiling, indicating the contour of the fillet.
  • We carry out similar actions with the adjacent bar, we also lean it against the ceiling and draw a pencil line.
  • Then we carefully examine the improvised drawing. The point where the mowing lines intersect is where the skirting board needs to be cut. But it’s better to play it safe. Again, one by one, attach each fillet to your ceiling and already on them mark the place according to which the trimming will be carried out. From this place to the other edge of the plinth, you need to draw a line. Then, along all the drawn lines, you need to cut off fillets.

If, after all the work done, you notice that the skirting boards are unevenly installed, there are gaps, cracks or other errors in the work. do not rush to despair and redo everything again. Putty or other sealant will help you out. With them, you can accurately fill the voids that have formed, without damaging the skirting boards and their appearance. Fast and convenient, and most importantly. beautiful.

How to dock in corners

If the installation of the first corner is completed, we can assume that you have already learned almost everything. “Almost”, because you still need to learn how to join the corners and cut the planks to length. When some part is already glued and there is a small distance to the corner, how not to be mistaken with the length? The answer is simple: leave stock.

At first, you can cut a piece 10-15 cm longer: it will be possible to redo it several times if something does not work out right away. Then you make a corner in the way described above, try it on dry, adjust everything so that the result suits you. Only then can you attach the already cut strip to the corner and mark the place to which it can be shortened. You need to trim at exactly 90 °. It is not necessary to use a miter box. Just try to put the knife (hacksaw) perpendicular to the surface.

Sometimes the unevenness of the walls or ceiling prevents you from gluing the plinth along its entire length, tightly pressed against the wall or ceiling, or you made a little mistake when cutting the inner corner, and you have a gap. To eliminate these defects, a white acrylic finishing putty is perfect. It can be painted well after drying, and with its help you can gently putty the joints. This putty is sold in a ready-made form, you do not need to stir it yourself with water and worry about non-compliance with the proportions, depending on the manufacturer. If you want to make everything aesthetically pleasing, then spare the money and buy a small jar. According to personal observations, 0.5 kg cans of ready-made putty will be enough for you both for all the flaws in the joints of the ceiling plinth, and for eliminating other minor errors during the repair.

And also for easier trimming of corners, you can use a clerical triangle, it will give you the ability to accurately cut a 45-degree angle.

One of the important factors to consider is the material from which the skirting board is made. Now they are made from PVC. polyvinyl chloride, expanded polystyrene (foam), wood and polyurethane. Depending on the material, glue and baguette trimmer should be selected.

The algorithm of actions is as follows:

  • The ceiling plinth must be attached to the place of gluing and the necessary measurements must be made.
  • After the fillet, you need to put the top on the bottom of the miter box tray. In this case, the lower part of the plinth must be pressed against the wall of the tool.
  • Next, you need to cut the skirting board at an angle of 45 ° using a saw or knife. When cutting, it is important not to overdo it with pressing force, as chips may remain on the plinth.
  • So you yourself need to cut off the butt skirting board, at the same angle.
  • At the end, you need to dock adjacent fillets at the place of gluing, while adjusting the cut line with a knife.

Trimming outside corners

Before gluing baguettes in the corners without a miter box, you need to properly cut the corners:

  • Attach the ceiling fillet as if it were to the right of the corner point.
  • Attach a fillet to the left of it, draw a line along the ceiling until the mowing lines intersect with each other.
  • Mark the fillets where the mowing lines intersect and where the corner point of the room is.
  • Connect the marks with a line on the fillet, walk along them with a sharp knife.

Important! The cut should go inside the fillet.

  • Check the joint along the corner, cut if necessary.
  • Glue the fillet in place.

Trimming inner corners

You can cut the ceiling plinth in the corners without a miter box, following this algorithm:

Important! Do not make great efforts when cutting the strip, as it will still deform under the influence of the glue.

Ceiling plinth. what is it?

Ceiling plinth (or fillet, in a scientific way) is made from a variety of materials. It can be polyvinyl chloride (PVC), polyurethane, expanded polystyrene or wood.

The highest quality of all of these are polyurethane fillets. They are durable, elastic and moisture resistant.

However, polyurethane skirting boards also have their drawback: they do not tolerate sudden changes in temperature. This is why cracks and deformations can often be seen on polyurethane ceiling skirting boards that sit above kitchen stoves.

Styrofoam skirting boards are very similar in quality to polyurethane skirting boards. True, they are not very durable and, under mechanical stress, they can break.

The cheapest option is PVC fillets. However, they are not very elastic and not electrostatic, which is a clear disadvantage.

Ceiling skirting boards come in different sizes and shapes, and can also have a relief surface texture. At the junction of the ceiling with the wall, they are attached, as a rule, with glue.

Important advice! In low rooms, you should not use wide ceiling plinths, but in high rooms, on the contrary, narrow ones. For standard rooms with a height of 2.75 m, fillets are usually chosen, the width of which is 45 mm.

As a rule, special corners are sold along with the plinth, which can be internal or external. If you decide to abandon the use of such accessories and dock the skirting boards on the corners of the room manually, then just knowing how to cut the corner of the ceiling skirting board will come in handy.

Preparing the skirting board for gluing in the corners of the room

So that there are no cracks in the corners of your room, you need to be able to correctly cut the corner of the fillet. This can be done using the following tools:

  • Miter box;
  • Saw for metal;
  • Sharp knife.

What is a miter box? This tool looks like a tray with slots made at certain angles. For trimming plastic skirting boards, a miter box with angles of 45 and 90 degrees is used.
