Plinth On The Ceiling How To Cut The Inner Corner

How to cut the ceiling plinth in the corners The final stage in the design of the room. Installation of a ceiling plinth. How to make a corner correctly so that everything will come together without gaps, how to join in the outer and inner corners. Read on.

With decorative corners

There is one more, simpler way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory decorative corners. They are installed in a corner, strips are glued to them closely. It is very simple to cut them if necessary: ​​by a few millimeters with an ordinary clerical knife.

How to cut ceiling plinth in corners

The quality of the ceiling finish greatly affects the appearance of the room. Therefore, they try to do everything perfectly, or very close to it. The finishing touch to the design is the ceiling plinth. They give the finish a complete and holistic look. The strips themselves are mounted on flat surfaces simply: on special white glue, but problems arise with the design of the corners. Without knowing how to make the corner of the skirting board correctly, a lot of material deteriorates. We will tell you about how and what to cut it in the corners.

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 first way with a miter box

The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool represents the oldest and simplest carpenter’s tool, designed for cutting wooden parts at an angle of 90 and 45. There are types of such a device for professional work, with a swivel mechanism, in which the cutting tool can be rotated and fixed in any position.

How to cut a ceiling plinth correctly

Ceiling corners are divided into internal and external, the method of joining them is slightly different.

Inner corner

  • We make the correct measurements.
  • We install the plinth strip in the miter box so that this position exactly coincides with the placement on the ceiling.
  • 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 in the photo.

Outside corner

  • 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.

Checking the smooth docking

All the nuances are well described:

Acute

How to make the angle of the ceiling plinth less than 90 degrees? You can adjust the corners in plastic models in the same way as described above. That is, using saws and heating. It should be borne in mind that stiffening ribs prevent the part from bending during heating. Therefore, they need to be trimmed as needed. For external mating, it is enough just to make an incision, and for internal mating, you will need to remove part of the partitions so that they do not interfere with the correct displacement of the corner shoulders.

How to dock?

The methods of joining moldings depend on the material, as well as on its decorative features. For example, it is desirable to mount an array on hardware. The large weight of the profile with an impressive width of the product will require the use of appropriate self-tapping screws. Adhesive solutions in this case will be unreliable. It is a completely different matter when it comes to foam or gypsum profiles. These are fairly lightweight and easily workable planks that adhere perfectly to glue and putty.

When combining two or more planks, the mating angle must be taken into account. On flat areas, docking at 90 and 45 degrees is used. In the first case, the molding is simply trimmed, and in the second, it is trimmed according to a template or with a miter box.

Internal corners

How to join the ceiling plinth in the inner corners with a simple relief? For this, prepare a suitable tool.

To cut the foam profile, you can use a metal hacksaw or hot nichrome wire. The good thing about hot fitting is that the wire thread makes a cut quickly, almost instantly, without leaving any burrs or roughness.

For laminate, plastic, as well as gypsum, a metal sheet is suitable. Fine teeth will avoid unnecessary chipping on skirting boards.

How to properly cut a profile at an inner corner? These angles have one peculiarity. They are formed by elements whose bottom edge is longer than the top. That is, when you attach them to the ceiling, the lower one will press against the walls, and the upper one will recede inward. It turns out that the upper perimeter of the skirting board will be smaller than the lower one.

The corners for the skirting board make the task much easier. They already have the necessary shape, so it is enough to dock them in a straight section with fillets. For plastic models of corners, an overlap joint is used, while for other materials, the technology allows you to make a snap joint.

How to trim a ceiling plinth using a miter box template

Something resembling a miter box can be done by applying the required cut angles to paper, cardboard or wood. Draw two parallel mowing lines, locate the center, and then set the required angles using a protractor. The advantage of this method is that you can postpone any angle, including more than 90 degrees. Of course, before cutting the corners of the ceiling plinth, you must first check the angle between the walls with a corner and measure it with a protractor.

The technique for cutting a ceiling plinth using a painted miter box is exactly the same as using the miter box itself. We press the plinth plank to one of the parallel lines, then set the hacksaw at the desired angle, which is already outlined, and cut it off.

How to cut a corner of a ceiling plinth using a miter box

The miter box is a simple carpentry tool that allows you to cut the workpiece at the desired angle. Most often it is a plastic, wood or metal tray with vertical slots for cutting at an angle of 90 and 45. There are also more complex miter boxes for cutting at 90, 60 and 45 degrees. For more professional work, a miter box with a swivel mechanism is used, where the hacksaw can be fixed at any angle to the workpiece.

How to cut a ceiling plinth with a miter box:

  • We apply the plinth to the ceiling, measure the required length.
  • Then we install the plinth plinth in the miter box so that the position coincides with the position of the plinth on the ceiling.
  • The plinth strip should be pressed against the far wall of the miter box.
  • We hold the plinth with your left hand.
  • We choose such a position of the hacksaw when the angle is 45 degrees and the handle of the hacksaw is as close as possible to the left hand.
  • We cut the workpiece without making excessive pressure on the saw.
  • The next step is to trim the plinth striker. We also install it to the far wall of the miter box.
  • Press and hold with your right hand.
  • We choose such a position for the hacksaw when the angle is 45 degrees and the handle of the hacksaw approaches the right hand.
  • Cut off the skirting board.

Next, we join the trimmed plinths and check the cutting accuracy. For a more accurate orientation, they also say that to complete the inner corner, it is necessary to start cutting from the front of the skirting board. Wooden skirting boards will most likely need to be filed after trimming.

How to cut a ceiling plinth with a miter box outside corner:

  • In order not to be mistaken with the dimensions, it is better to start by marking the inner corner, and then cut out the outer corner. Otherwise, a situation is possible when the planks may not be enough in length.
  • It is necessary to attach the plank to the ceiling and outline the dimensions.
  • Install the plinth strip and press it against the nearest wall.
  • Hold it with your left hand and choose a position for the hacksaw at an angle of 45 degrees, when the handle approaches the left hand.
  • We cut off the workpiece.
  • We install the striker to the nearest wall, hold it with the right hand.
  • We set the hacksaw at a 45 degree angle when the handle approaches the right hand.
  • We cut off the workpiece and join the corner.

Trimming the workpiece with a miter box is only suitable if the angle between the walls is even 90 degrees. If the accuracy is poor, you will have to use other methods.

How to trim the corner of a ceiling plinth using ceiling markings

Marking the skirting board on the ceiling also allows you to cut the corner straight and precisely. The only drawback of this method is that it is difficult and inconvenient to keep the plinth strip suspended during the cutting process. Otherwise, you can mark the cutting angle in this way even more accurately than in other ways. Applying the plinth to the installation site, all wall flaws and deviations in the angle size are immediately taken into account.

Cutting the corner of the skirting board:

  • The first step is to cut two workpieces at a 90 degree angle.
  • Then we first apply one plank, resting its end against the perpendicular wall. We draw a line on the ceiling, outlining the contour of the plinth.
  • We remove this bar and apply a striker, also resting its butt against the wall. We outline the line.
  • The intersection of the marked lines will be the mark at which the skirting board needs to be cut.
  • Again, we apply each bar in turn and mark the cutting point on them.
  • We draw the line from this point to the other edge of the plinth.

We cut off the skirting boards along the outlined lines, join them and apply them to the installation site. Note that this method makes it easier to cut inside corners.
