Masking joints and painting

If, after gluing the ceiling plinth, there are small gaps between the strips, this is absolutely not a problem, because they can be easily eliminated by rubbing in a white sealant. If you have not yet whitewashed and painted the ceiling, then the following is the best option.

With a light putty, you need to go over all the glued strips, smearing them like a coloring compound, and after drying, remove the excess with a fine sandpaper or a special grinding sponge for plastering. After such a final finish, the ceiling and moldings will become a single whole, and you, in turn, will not find a single gap.

After you have glued the ceiling plinth and eliminated all the flaws, you can start painting the plinth. The process of painting the skirting board is considered optional, but if you want to give your ceiling a finished and more attractive look, then you still need to paint the skirting board.

How to make installation

You need to cut with the help of such tools: a miter box, a hacksaw, a sharp knife. Insert a piece of material into the miter box at a 45 degree angle and press down firmly. Now it remains at the right angle and cut the ceiling plinth from the right side.

Take your time to glue the cornices along the straight sections. First tackle the corners in this case, you can trim them if necessary, or sand them until you get a good joint.

Now let’s figure out in more detail how the installation of the ceiling plinth is done with photo examples.

How to cut the inner and outer corner of the ceiling fillet

Thus, we cut the skirting board, if you need to get an outer corner.

As a result, such fillet edges are obtained.

Then the inner corner. Pay your attention, but at what angle and on which side of the miter box you need to cut the ceiling plinth.

This is what happened in the end, after cutting and gluing to the wall.

The do-it-yourself apartment renovation website advises to start practicing in pieces, if everything works out, then go ahead, cut out the inner and outer corners.

If you did everything correctly, then you managed to cut the first corner. You can glue two corner skirting boards to the wall.

If you have chosen a way to fix the ceiling plinths before gluing the wallpaper, then you need to fix them with a putty. Apply the putty to the fillet with a spatula. And attach it more tightly to the wall. Remove residues with a spatula or a damp cloth. The cracks can also be covered with putty.

Tips to ease the installation of ceiling dumbbells:

  • To correctly measure, the bar is measured between two corners. At the same time, for internal corners, the length is measured from the internal elements, and the distance from the external corners is measured from a point that is spaced from the internal by a distance equal to the width of the plinth deep into the room.
  • When installing foam plinths at the junction between the wall and the stretch ceiling, glue is applied to the part of the plinth that is in contact with the wall, not the canvas.
  • The final fixation of the skirting board is carried out after adjusting the corner of the adjacent strip to it.
  • If there is a right angle against the wall, ceiling and floor, it is easier to adjust the planks at the bottom by spreading the parts on the floor or on a prepared table.
  • Small gaps remaining in the corners are putty.
  • Particular attention should be paid to the installation of rare wood skirting boards. In this case, the putty of the gaps will most likely not give the expected result. A bright spot appears on the texture background.

Well, are the inner and outer corners ready? So you are doing the fillet installation correctly. Now take the next plank and in the same way attach it to the wall to the glued plinth and do not forget to grease the corner joint. When you proceed to the next corner, then carefully measure the distance that remains, and cut off the missing part, everything should be very accurate. The side that goes side by side with the skirting board will remain unchanged. So cut out every corner. When everything is glued, then they can be painted to match the color of the ceiling. Good luck gentlemen and remember to cut after determining the exact size.

How to get the correct angle

Most of the problems when working with skirting boards arise in the design of corners. Since the surface of the products is complex, it will not be possible to simply cut off at the desired angle: it is also necessary to cut so that they dock and preferably without large gaps. There are actually several ways to make the corner of your skirting board perfect (or almost).

Using a miter box

If the corners and walls in the room are even, you can use a special miter box carpentry tool. This is a groove in the form of an inverted letter P, in which the mowing line is outlined for cutting at an angle of 90 and 45. The part in which you want to cut is laid inside, the saw is inserted into the guides. The part is held in place, cut at the desired angle.

Press the part that is on the ceiling to the bottom of the miter box. The other side is closer to you and raised. Lean it on the wall of the device so that it does not stagger when cutting. That is, the front of the skirting board turns out to be turned away from you. Do the cutting direction as shown in the photo below. By folding the two cut pieces together, you get a projecting outer or outer corner.

What and how to cut

Working with skirting boards made from different materials means using different cutting tools. When working with a wooden skirting board, it is more convenient to work with a saw on wood. All others, including plastic ones, made of polystyrene and other polymers, are better cut with a blade for metal. The result is a smoother cut, less burr. Saws are usually used when working with a miter box.

Corner design looks attractive

When working with polystyrene skirting boards, they cut them with a good stationery knife without special devices. Its blade is quite thin and even, the cut is smooth, not wrinkled. If you work with a saw with polyurethane or polystyrene, do not press hard: you can wrinkle.

In general, to get used to the tool and material a little, take a piece and practice on it: cut, saw, trim. So there will be fewer problems when working.

  • The plinth should be firmly pressed against the opposite wall of the miter box. Hold and press with your free hand.
  • We put a hacksaw at an angle of 45 in a special hole and cut off the part.
  • The adjacent part must be cut in the same way, only in a mirror image, as shown.
  • Measure the length of the plinth from the nearest wall to the outer corner, leave the fishing line on the wrong side with a pencil, indicating the desired length. It should be noted that the edge (its upper part) should protrude slightly outward.
  • The plinth is moved to the miter box and cut off.
  • The adjacent strip must also be measured with a margin and cut off in a mirror image to the first part.

Trying on the ceiling plinth: the joining of the parts should be perfectly flat. If the result is not achieved and there are irregularities at the joints, you can trim the edges with a regular knife to a perfect fit.

Fillet trimming

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 exactly 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 by 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, at the plinth, you need to cut off the striker. It is also placed at the far wall of the instrument, holding and pressing, this time with the right hand.

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

Then the finished, already cut strips are joined together, 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. The cuts usually have to be adjusted with a file.
