How to saw a skirting board with a chair

Modern finishing materials for the design of the joint of different planes or overlapping the line of connection of different materials in the finishing are made of polystyrene foam and polyurethane foam. The decorative parts made of polystyrene foam, in simple terms, foam plastic, are the cheapest and most fragile products. Technical features of the material. pressed granules-balls, do not allow you to make a complex relief pattern. But if the profile of the cornice is uncomplicated, then decorative elements of styrofoam are quite suitable for finishing, especially since the fragility of the material at the height of the ceiling does not matter. Stucco from polyurethane is a more correct, although expensive material for decorative finishing. Polyurethane details are dense, solid and accurately convey complex topography. There are also wooden mouldings, but some complex elements of wood in regular construction stores are difficult to find.

Mounting the ceiling plinth

Ceiling plinth of polystyrene foam or polyurethane foam does not require any complicated devices for installation. It’s easy to cut, and will require adhesive to install. What you’ll need:

  • hacksaw;
  • A construction knife with a replaceable blade;
  • pencil;
  • Jigsaw;
  • glue;
  • glue assembly gun;
  • Finishing fine filler.

Usually, decorative ceiling rails are available in the form of straight products, with a length of 2-2,5 meters. And if in the installation of rectilinear sections there are no special problems, then how to perform internal and external corners? To join two straight pieces in a corner, they must be trimmed “on the bevel”. Consider how to cut the ceiling plinth, so that the two parts fit tightly at the junction.

For 90-degree corners, which are the majority in the rooms, straight pieces should be cut along a line at 45 degrees. There is a special tool for this operation. the plier. On sale there are complex units with this name, allowing to cut at different angles, most often they are also equipped with a cutting tool. But in its simplest incarnation, the crossbar is a U-shaped box with slots at different required angles.

Trimming the baseboard with a jig saw

If you are able to join three pieces of, for example, thick plywood, at right angles, mark corners and make even cuts according to these marks, then you do not need to spend money to buy this tool. Decorative profiled mouldings can also be cut at an angle without a jig, but sometimes it is more convenient to use this device. There is bound to be an error when sawing. In order to minimize this error, and need a power tool. Cutouts in its side walls do not keep the hacksaw at an angle, making the saw perpendicular to the surface.

The difficulty to cut the ceiling skirting boards is that a nominally straight angle is not always perfectly straight. Therefore, the marked corner of 45 degrees, may actually be 44 or 46 degrees, or some other. The most ideal way would be to mark each part according to the actual state of the corners, and it is better to make a cut according to this marking, using a trimmer, or simply, trimmer. Therefore, if a large volume of installation of cornices, skirting boards, moldings and other decorative details, then perhaps the purchase of such an electric tool will be justified.

Using an electric saw

The mitre saw cuts precisely at an angle.

For perfect sawing of ceiling skirting boards, it is best to use an electric mitre saw, where you can set any direction and saw out the desired slope as accurately and precisely as possible.

skirting, board, properly, types

No special effort is needed. You just need to set the parameters and lower the saw blade onto the surface to be cut, be it wood or plastic. But you can cut a skirting board with less expensive tools, too.

Tools needed for the cut

  • Chisel. a special tray, consisting of three surfaces. Its sides contain special slots at right angles to the axis. They guide the hacksaw blade at the right angle when cutting.
  • A pencil, a washable marker, a construction tape measure.
  • A knife, fine-toothed hacksaw or good mitre saw. Plastic baseboards can be cut with an ordinary sharp knife or metal saw.
  • Sanding the wooden skirting boards for painting is a must.
  • Fixing elements, self-tapping screws, nails, dowels.
  • Hammer, electric screwdriver.


Before you start, you first need to calculate the number of skirting boards you need. For this purpose, the standard length of the product (2.5 or 3 meters) multiplied by the perimeter of the room and take a reserve of 10% for trimming. For installation you will also need fasteners, plugs.

How to join skirting boards correctly in the corners

Corner corners that are properly designed look attractive

As a rule, the design of corners, both internal and external, takes most of the time. Due to the fact that the ceiling plinths are characterized by a very complex shape, it is not so easy to just take and cut them at the right angle. It is necessary to cut so that they docked in the corner without noticeable gaps. To make the corners literally perfect, there are several ways.

Using a power plier

The chisel, as a tool, is suitable if the corners of the room are conjugated at an angle of 90 degrees. The tool is a U-shaped trough, turned upside down. On the walls of the chute cuts are made at different angles. To evenly cut the decorative element, it is placed inside the gutter, and then the saw cuts the element at the desired angle.

This is what the jig looks like. Can be plastic, wood or metal

Due to the fact that the skirting boards have a complex shape, they must be placed in the gutter so that they simultaneously pressed on two surfaces. the bottom and side. Depending on what angle is formed, the skirting is pressed to the bottom and side, or opposite, or the near surface.

How to cut a corner on the ceiling plinth: properly set it in the jig

Ceiling baseboards are attached to the ceiling with one hand and the other to the wall, so the part that is attached to the ceiling, laid on the underside of the chair. It is very important to hold the skirting board firmly and firmly during cutting, because otherwise the cut surface is unlikely to be flat and smooth. Having cut in this way the left and right part, you get either the inner or outer corner.

First, both parts are applied to the place of attachment without glue, in order to control the quality of the work. In case the angles do not match, they are corrected with a suitable tool. The advantage of polystyrene ceiling plinths is that small errors can be hidden by covering them with putty.

After a final check, a thin layer of special adhesive is applied to both surfaces of the skirting.

How to make the inside corner of the ceiling plinth with a wire cutter

The technique of fitting ceiling baseboards in the corners is almost the same, regardless of which corner it is, internal or external. After applying glue, the skirting is pressed against both the wall and the ceiling. Naturally, the effort must be controlled, especially if the decor elements are made of foam. Not only that, you need to work with gloves, so as not to smear the surface of the baseboards, which easily gets dirty.


Despite the fact that gluing ceiling baseboards is not that difficult, there are tips worth heeding:

  • The walls should be clean and dust free. Any dirt will reduce the adhesive properties of the base.
  • The underside of the slats is better to make a rough surface, as a smooth surface has a low quality of adhesion to the surface.
  • It is important to choose a quality glue with a good fixation, especially for heavy baguettes. Also, do not use glue with a solvent for skirting boards of polystyrene, such a composition can spoil the material.
  • After attaching the ceiling skirting boards, do not allow draughts in the room within a day, the glue must be well cured.

Cutting the baseboard

Before attaching the ceiling plinth, it is necessary to make very carefully and accurately the trimming of the corners of strips, so that they perfectly evenly dock in the corners. This is where you’ll come in handy with a wire cutter.

It is important to observe the simple rules. The main principle. trim the corner first. And only then make the trim on the length.

Note that the main part of all baseboards is asymmetrical, that is, one side of it is longer than the other. The long part is fastened to the wall, and the short part is fastened to the ceiling (see the.

How to cut a ceiling plinth: step by step instructions from the real experts). If your room has even corners, you have no problem with how to attach the baseboard. Simply slide the fillet into the cutter and use a sharp knife to cut it at a 45 degree angle.

Tip! At the bottom of the mortiser must be the side that will be fastened to the ceiling. The tacker must be held straight when trimming. If your hand shakes, the joint will be a gap that is difficult to seal.

How to evenly trim the corner of the ceiling plinth with it?

The plier is an uncomplicated tool used by carpenters. It can be used to cut any piece at the right angle.

It is usually a wooden, metal or plastic tray, which is made to cut at an angle of 45 ° and 90 ° special vertical slots.

There are complicated designs, which in addition to the named corners also have a hole to make a 60-degree cut.

A special plank is available for professional work. Its swivel mechanism allows you to fix the cutting blade in relation to the workpiece at any given angle.

Inner Corner

The prepared skirting board is applied to the ceiling, and the required length is set aside.

Then this same plank is inserted into the mortiser exactly as it will be positioned on the ceiling. It must be pressed against the far wall of the fixture. In this position, the baseboard is held by the left hand.

The blade of the hacksaw should be in such a position that its angle is 45 degrees, and the handle as close as possible to the hand. Trying to avoid exerting pressure on the saw, we carefully cut the workpiece.

Next, the skirting board must be cut from the mating strip. It is also placed against the far wall of the tool, held and pressed down, this time with the right hand.

Similar to the previous procedure, the position of the hacksaw. its handle is close to the hand at an angle of 45 degrees. The baseboard is trimmed.

Then the finished, already cut slats are joined together. the accuracy of fit is checked. It is believed that for better orientation, in the manufacture of the inside corner, it is better to start cutting from the front of the product. The places of the cuts usually have to be further adjusted with a file.

Outside angle

The correct way to observe more accurately the dimensions, first start to mark the inside corner, and only then move on to the outer.

Otherwise, it could be that the entire length of the plank is insufficient.

The strip is applied to the ceiling, and marks are made according to its size. Holding the left hand, the ceiling plinth is pressed to the closest wall, the handle of the hacksaw is close to the hand. The workpiece is cut off.

The counter bar is pressed against the nearest wall, holding it in place with the right hand. The blade of the hacksaw should be at an angle of 45 °, the handle of the tool is close to the hand of the master. A piece of the workpiece is cut, the angle is neatly docked.

Such edge trimming is good in cases where the angle between the walls is even and straight (90 °).

If its performance leaves much to be desired, it is worth using another method.

Marking on the ceiling

The method with a marking on the ceiling allows you to cut the corner accurately and evenly. It has one disadvantage. it is quite inconvenient to hold the plinth plank by weight during the procedure.

Otherwise, with this method, you can mark the corner for cutting even more precisely than with other methods.

When the skirting board is placed at the intended installation location, all size variations and inaccuracies are immediately visible and accounted for.

Cutting a corner

First you need to take a pair of blanks, then cut them at a right angle. With the end of the slat against a perpendicular wall, we put one slat. Let’s draw a trimmer line on the ceiling, following the contour of the baseboard. We remove the first slat, then in the same way, pressing the end into the wall, attach the responsive slat. Exactly the same way we mark on the contour line for the trimmer.

The intersection point of the two separate lines is the mark at which the piece is cut. Each skirting board is placed against the surface again and the point of the future cut is marked on both of them. From the found point to the other edge of the baseboard plank, we draw a trimmer line. Skirting boards we cut on made earlier marks, we accurately join, we dispose in a place of their installation.

This method allows you to handle inside corners more accurately.

Joining ceiling skirting boards in straight sections

How to join the corners of the ceiling plinth correctly, we have figured out, now let’s determine how the docking is performed in straight areas (see “The method of joining a ceiling plinth”). Plastic ceiling plinth: the first acquaintance).

The edges of the skirting strips must be sanded before joining the ceiling plinth in straight sections

  • The next slat joins the previous one in the same way. When reaching the straight plank corner plank far corner on the same wall it is tried on the length at the place of installation and apply a mark to perform the cut. Further on the mark accurately cut the plinth at a right angle.

Advice! In order for the ceiling plinth strips to form a perfect joint, the cut edges should be carefully sanded with fine sandpaper.

In our article we found out how to join a ceiling plinth in the corner of the room and in straight areas, we described the rules for using the plinth trimmer. Now you only need to arm yourself with the right tools, buy, actually, the skirting board and bravely proceed to perform the work yourself. And for those who have not yet fully understand the intricacies of the joint, we recommend to find on the Internet topical video for a clearer picture.
