How To Cut The Ceiling Plinth Correctly

There are several ways to trim corners. Each of them is used depending on what tools are at hand and on what material the baseboard is made of. Each of them requires a certain skill, but some are more and some are less time consuming. The exact choice depends on the experience and capabilities of the builder.

How to make a miter box yourself?

If desired, the miter box can be made at home. It can be crafted from wood or iron. The dimensions of the workpiece DO NOT play a special role, but the wider it is, the more accurate your cuts will be. However, if the width is greater than the length of the hacksaw, with which you will cut the baseboards or boards, then the dust will be extremely inconvenient, so it is not necessary to take too wide a workpiece.

First, a transverse line is marked in the center of the workpiece. Then, marks are made at a distance of 1/2 the width of the workpiece from the intersection of the straight line with the edges of the workpiece. Then these marks are connected crosswise, as shown in the figure.

Wooden miter box, fastened with self-tapping screws

Then the process of marking the side walls with a miter box begins. Attach them to the already marked base and make marks, focusing on the marking of the base. Then draw straight lines from THESE marks across the entire wall.

The scheme of making a wooden miter box

After that, the process of installation with a miter box begins. The walls must be attached to the base with self-tapping screws, if the fixture is made of wood or chipboard or corners with bolts, if it is made of steel. Only after installation in the miter box, sawn through the saw slots.

DIY installation

Once the corner is properly cut, it must be attached to the wall. This can be done in the following ways:

    Thin carnations. This method is suitable for wooden skirting boards attached to wooden walls. You cannot drive a nail into a concrete or brick partition.

Inner corner

The prepared plinth is applied to the ceiling, the desired length is set aside.

Then this very strip is inserted into the miter box in the same way as it will be located on the ceiling. It must be pressed against the far wall of the device. In this position, the plinth is held with the left hand.

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

Next, cut off the striker in the skirting boards. It is also placed in the far wall of the instrument, holding and pressing, this time with the right hand.

The position of the hacksaw is similar to the previous procedure. its handle approaches the hand at an angle of 45 degrees. The skirting board is trimmed.

Then the finished, already cut strips are docked. the accuracy of the fit is checked. It is believed that for better orientation, when making an inner corner, it is better to start cutting from the front of the product. Places of cuts usually have to be adjusted with a file.


For the outer corner. the plinth is applied to the right side with a miter box (or to the ones closest to you, if the template is placed across the desktop), aligned along the plane and the wall, and then cut off or sawed off with the introduction of the template.

Making a miter box with your own hands

Unfortunately, not all houses have the entire arsenal of carpentry tools, but you can make a similar miter box yourself. For this, a rectangular tray of planks is knocked together, then grooves are sawn in the walls. at an angle of 45 °.

To measure the angle, you can use 2 knocked down boards and a protractor or an ordinary right-angled triangle. that’s the miter box and you’re done!

A ceiling skirting board is a narrow decorative demarcation between the ceiling and the adjacent walls.

It is very convenient for them to mask the joints on the walls and on the ceiling, especially if they have a different structure and are NOT made too neatly.

Its presence makes the design of the room clearer and more complete.

Often people ask themselves the question: how competently and neatly the room is separated with a ceiling plinth?

This is especially true for those cases when the owner of the house prefers repairs done with his own hands.

Plastic skirting boards and their properties

The advantage of plastic skirting boards

This type of skirting board is quite popular at the moment. It can be used to decorate a room with any design.
It is moisture resistant and does not burn. Also tolerates temperature changes and various influences on it.
Material features:

  • Its surface can be smooth or rough. Relief on a plastic skirting board is not often found.
    For such a production technology, you will need to use special equipment and due to this, the cost of the plinth will be quite high.
  • The surface can have various shades. The plinth itself is either angular or flat. It is used for finishing plastic ceiling surface.
  • It can be mounted using liquid nails or construction glue. A fairly common option is double-sided tape.
    You can only use it on a plastic surface, which is similar in properties and characteristics to a plastic skirting board.
  • Small amounts of liquid nails are applied. They will be able to securely fix the skirting board to the surface.
    You can also use a construction stapler. The joints of the material are treated with white sealant, if the plinth is white.
  • How to cut plastic skirting boards correctly? Everything is very simple. Since the material is not very thick, you can use a stationery knife for work.
    A bolgraka that makes an even cut is also suitable.

You can fix a plastic skirting board in the corners using decorative corners. Lightly cut skirting strips are inserted into them on both sides and fixed with glue.

How to properly cut the corners of ceiling plinths: both with and without a miter box

When planning the installation of ceiling plinths in the premises of their apartment, many people think about how difficult the work can be. However, everything is not so scary: the ceiling plinth can be installed with your own hands. the main thing is to know about some of the features of the materials from which this finishing element is made.

How to cut a ceiling plinth correctly

It is known that in order to obtain a perfect articulation of two corner pieces of the ceiling plinth, it is necessary to correctly form the cutting line of each of them. In this article you can learn how to properly cut the ceiling plinth, as well as familiarize yourself with the topic of the devices that are necessary for this.

Methods for cutting skirting boards

Cutting technology

There are the following ways to cut the skirting board:

  • Cutting with a miter box.
  • Cutting with a special stencil.
  • Cutting by applying pencil markings.

A miter box is a special device with which you can form an arbitrary angle from those that are in its set of cuts.

Using a miter box

When working with this device, the skirting board must be inserted in exactly the same way as it will be located on the ceiling. Holding the upper part of the workpiece, its lower edge must be pressed against the wall of the fixture and cut in the shape of your choice.

You can use a conventional metal hacksaw to prepare your plastic skirting boards. But when using it, you should not make significant efforts, as this can lead to the formation of chips.

Arbitrary corner preparation

Stencil cutting Since the walls in the rooms do not always adjoin one another at 90 degrees, it is worth familiarizing yourself with the technique of preparing an arbitrary cut angle.

This technique is implemented, as a rule, in the following two ways:

  • Using a cardboard stencil, the halves of which are obtained by cutting it at the angle you need. Using such a stencil as a template along which cuts of skirting boards are formed, you can get the perfect corner joint.
  • The second method involves preparing the cutting site by means of pencil markings and is as follows:
  • Pencil markup method both joining blanks are sawn off at an angle of 90 degrees;
  • One of them is applied to the corner, and then a line is outlined on it for the abutment of the plinth to the ceiling;
  • The same actions are carried out with the second workpiece (on the adjacent wall)
  • The point of intersection of the two lines obtained should be carefully transferred to both blanks;
  • From the marks obtained on the blanks after transferring them from the ceiling, draw an oblique line to the opposite corner of the plinth and get a cutting line.

Preparing the cut line Pay particular attention to the fact that with this method of marking it is necessary to maintain maximum accuracy. The quality of the resulting joint will completely depend on how accurately you carry out this procedure (and, of course, on the accuracy with which you will shape the cut on the blanks).

In the same sequence, the cutting lines for the outer corner are prepared. But at the same time, the point of intersection of the marking lines is transferred to the plinths, there is a need, since in this situation it is the upper point of conjugation of the corner parts of the blanks. In this case, the point of contact with the wall is transferred.

The final stage of work

Final adjustment of the skirting board

Upon completion of the operations to form the joints, a control check of the fit of the blanks on the cut should be carried out.

In the event that there are gaps at the joint, you will have to make an exact fit by slightly cutting the skirting board or processing the sections with sandpaper.

And we will acquaint you with how to properly cut the ceiling plinth more accurately. Fitting the mowing line Docking of adjacent skirting boards should be done before you start marking and trimming its length. In the reverse order of operations (first. the length, and then. the angle) and with a failed attempt to design the joint, you risk completely ruining the workpiece.
