How to cut a 90 degree angle skirting
Why do we need skirting boards on ceilings?
Ceiling skirting is not just a decorative part of the ceiling finish. It assumes several important functions:
A Simple Trick to Install Baseboard Corners Perfectly
- Concealing defects in the joints between the ceiling and the adjacent wall construction.
- Concealed cable routing, e.g. when installing video surveillance or fire alarm systems.

Types of angles
Angle docking and trimming the baseboard differs depending on the type of angle, there are: internal, external and non-standard.
The inside corner, in other words, the angle of the room is less than 180, usually 90. When trimming an inside corner, the bottom of the ceiling plinth always protrudes over the top. The first thing you must still measure the angle between the walls, if it is standard and equals 90, then the strips are trimmed at an angle of 45. Baguette, which is glued to the right side should be trimmed to the left, and the left plank to the right.
Outer corner or outer corner is less common, it is more than 180, usually about 270. In working with such angles it is exactly the opposite. The edge of the skirting board, which will be pressed to the ceiling, should be larger than the bottom.
Nonstandard angles. Angles with more or less than the standard degree of 90 and 270, as well as various kinds of roundings, are most often understood as such. Trimming in this case is done by eye or with a marking on the spot. Sections with roundings are assembled from several small elements, each of which is fitted in turn.
With a planking frame
45 degree baseboard is much easier to cut in a jointer. You do not have to try it on, to work on the “at random”. All slopes are already clearly aligned on the template. By the way, you can also make it yourself. Here are instructions for a simple disposable template.
Before you cut the ceiling plinth in the corners, measure the length and place a mark. Put the rail in the jig as it will be fastened further.
Clamp it to the far side of the template and hold it with your left hand. Find the slot responsible for 45 start sawing. Cut the second rail in the same way, only now hold it with your right hand and use the second slot on the same side of the jigsaw.
Now you can join the ceiling skirting boards in the corners. The walls can be caved in and the corner will not be straight. Then simply remove the excess material with coarse sandpaper or a construction cutter.
That’s it, now you know how to properly trim the ceiling skirting on the inside corners.
Start cutting from the outside of the molding. The exit saw tears the edge and the burrs can’t be removed.
Between how to file a ceiling plinth in the corners of the outside and inside there is little difference. Change only the location of the strip of molding, as in the picture.
When you do not have a jig saw
How to correctly cut the corner on a ceiling plinth if the factory platband is not available? In principle, it is possible, but the accuracy will be poor.
Mark the ceiling
Before you cut the corners on the ceiling moldings, mark the wall.
Use molding as a template, so that the intersection mark is exactly in the center.
Trim the corners
So, it’s time to cut the baseboard. Apply the molding to the wall, docking it with the marking. Perpendicular line falls on it this is the intersection point. From it, draw a scythe line to the opposite corner of the rail.
It remains only to cut the corner of the baseboard. With the 2nd strip the same procedure must be repeated.
The advantage of this method is that you almost do not have to dock the corners of the ceiling plinth. Even if the slope is not ideal, the point will fall exactly on the area to be cut.
In general, you can not suffer with the search for corners at all. It is quite acceptable to buy overlays.
Corners for the ceiling skirting foam are glued at the junction of the walls.

They have even planes on the sides, where you need to glue the ceiling plinth, and you won’t need to cut a corner. True, it is not appropriate in every design, and it is difficult to find them in stores.
Materials for ceiling plinths
Ceiling moldings can be of different widths, have a convex pattern on the front side and special recesses for engineering systems on the back side. Ties are made at a specialized factory of foam, its variety of polystyrene foam, polyurethane and wood.
Styrofoam is the most affordable finishing material. Its positive qualities: light weight, easy cutting and handling, possibility of finishing by painting in any color. The negative point. graining and low strength. even a small mechanical damage can break the integrity of the foam surface.
Polystyrene is a stronger variant of expanded polystyrene. It is also light in weight and in processing, but has a higher density and a smooth surface, is more resistant to mechanical damage, and lends itself well to painting. thanks to their low weight the two materials put insignificant load on the bearing walls.
Wood is the hardest and most impact resistant of all materials, which are used for the manufacture of fillets. Products made of it keep their appearance longer and can withstand considerable mechanical effect. In the style of some interiors, wooden friezes are the most applicable. Wood ennobles the room and fills it with warmth. However, it has a higher price than previous materials.
Products made of foam plastic, as well as polystyrene foam, have an advantage over wood. The softness of the material allows you to press the moldings as tightly as possible to the wall, ceiling and to each other. so there are no gaps. Achieve excellent docking skirting boards on walls that are not perfectly flat is possible if you use not a wide foam or polystyrene foam trim.
Tools to use
Depending on the manufacturing material, 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 the foam decor can easily be cut with an ordinary, sharp office knife. In most cases, a wire cutter is used, which allows for even cutting the skirting board at a certain angle. If a metal hacksaw is used, one should not press too hard, as the cut may be uneven, with burrs, and the material may crumple and become worthless. Polystyrene and polyurethane ceiling plinths require careful handling.
If there is no experience with such tools, as well as decor elements, 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.
Options for shaping corners
In any room can be two types of corners. inside and outside (external). In most rooms, you can see only internal corners. External are found only in corridor bends, on the outside of niches and protruding structures. The technology of trimming and adjusting the baguette for outer and inner corners is slightly different.
Most plinth laths have a complex configuration of the outer surface, which makes it difficult to form a corner. Some manufacturers of ceiling plinths offer special corner inserts and overlays, but often the joints of the walls in the premises are not equal to 90 °, so ready-made solutions are not suitable.
This may be provided by the layout or tolerances in the construction of walls and the lack of levelling plaster. Inaccurate fitting of slats to each other at the corner joint leads to the formation of visible gaps and gaps that spoil the appearance of the finish.
Several different methods are used to trim the fillets. How to join a ceiling plinth in the corners? Some of the main ones include the use of:
- a special tool, a jig, with guide slots at certain angles;
- laser level;
- A standard square, a tape measure, and a metal ruler.
Cutting with the help of a chisel is the easiest to perform, but is only possible for cutting at an angle of 45 or 90°. This limits its use or requires additional manual trimming.
The great secret of cutting
The inside corner of a ceiling plinth is the key to all. Professionals know that the ceiling plinth is cut on the outer edges and on the front side (it is also the inside). To cut the ceiling blanks was more convenient, a jig is used. It is extremely important to choose a good saw that will cut corners quickly and neatly. You can take an ordinary hacksaw for metal.
Quality ceiling plinth trimming is not possible without the right choice of materials. If the walls in the apartment is not flat enough, for docking in the corners will fit a smaller material. Due to the fact that it is quite flexible, the corners on the ceiling skirting boards are more accurate. How to cut a large ceiling plinth? The task is simplified when the walls are perfectly flat.
The next point is how to cut the baseboard depending on its location. The rule is very simple: the left side is always applied to the left side of the chair, and the right side. the right side. If you mix up the order of how to cut the ceiling plinth, then the docking will be a real problem.
Working with foam plastic is easiest. Let’s take a look at how to cut a ceiling plinth according to all the rules:
- Having measured the corners of the walls, let’s get to work. If they are perfectly flat and are ninety degrees, you are in luck. all you have to do is cut a corner of 45 degrees. The principle of working with the 2nd piece is exactly the same;
- And how to cut the corner of the ceiling plinth at curved joints? The radius of the corner between the ceiling covering and the walls is divided by 2;
- Once again, focus on how to properly cut the corners of ceiling plinth. Baguette for gluing on the left side has a characteristic cut on the right side, but the right-hand corner trim is cut on the left;
- Important question: how to cut the corners of the ceiling plinth inside and outside? The bottom edge always protrudes over the top, the opposite is true for the outer corner. Supple polystyrene foam and soft texture do the job. to fit such accessories is much easier. The only thing you’ll have to do is with wooden or plastic parts;
- When the inner and outer corner of the ceiling plinth is ready, the strips are tried on the ceiling. They will need to be trimmed according to the direction of adjacency to the surface;
- If the rough joint was successful, the baseboard is glued or screwed to the wall and ceiling. The seams reliably seal.

Ceiling skirting is called a non-widespread decorative delineation between the ceiling and adjacent walls.
It is very convenient to mask the joints on the walls and on the ceiling, especially if they have a different structure and made not too neatly.
Its presence makes the design of the room more clear and complete.
Often people wonder: how to competently and accurately finish the room with a ceiling plinth?
This is especially true in cases where the homeowner prefers repairs made with his own hands.
Features of working with different materials
If you install gypsum ceiling tacks, they are not cut like conventional ones. They must be sawn from the decorative side. In this case, the chips will remain on the reverse side of the product. If the sackcloth is attached to the back side of the stucco, it must be cut with a sharp knife. Next, use a special hacksaw to trim the fillets at a 45-degree angle to form the outer and inner corners.
