How To Cut Ceiling Plinths In Corners

The need to trim skirting boards

Installation of ceiling plinths (also called fillets) must be performed using the correct technology. However, there are no difficulties in it. the vast majority of fillets are mounted with glue. It is enough just to properly coat the product and hold it in the right place for a while.

But with how to properly cut the ceiling plinth in the corners, questions arise. When arranging a ceiling, there is always a need to process corners. but their value can have both a standard value (for example, a right angle) or a certain deviation. The latter case is possible if the room has a complex shape, or if during the repair it was not possible to align it.

How To Cut Ceiling Plinths In Corners

How to properly cut the ceiling plinth in the corners. options and methods for plinths made of different materials

Ceiling skirting boards are special parts designed to visually separate the walls from the ceiling, as well as to mask the joint between them. Such skirting boards are used almost everywhere and complement the interior of the room well. Installation of skirting boards is quite simple, but has a number of nuances. for example, to connect individual parts, you need to cut them off correctly. How to properly cut the ceiling plinth will be discussed in this article.

Finished corner pieces

Unfortunately, this method is not relevant in all situations. The dimensions of the corners produced at the factory are adjusted to certain standards. but the skirting boards themselves do not always meet the standards. Of course, such details can be combined, but the result will look unaesthetic. If corners of a suitable size are not available for sale, then you will still have to cut the baseboards yourself.

Polyurethane

Polyurethane skirting boards are the most expensive products. The high cost is due to a large number of advantages, including excellent resistance to moisture, high mechanical strength, reliability and elasticity. For most situations, this option will be optimal.

However, there are exceptions. polyurethane does not withstand temperature extremes. If you place such skirting boards in the kitchen near the stove, then over time, the polyurethane will deform and crack. The cutting of such fillets is performed with a special knife, and no complications arise during the work.

Expanded polystyrene

By and large, expanded polystyrene is a type of foam that has an increased margin of safety. The cost of products made of extruded polystyrene foam is slightly higher compared to foam, but the reliability of such skirting boards is much higher. It is already problematic to break such a detail.

Cutting styrofoam skirting boards requires any sharp tool, such as a construction knife or a hacksaw. Due to their high strength, it is much easier to work with such products. they practically do not break or deform during operation. There will be less waste in the end.

Styrofoam

Foam fillets are one of the cheapest options. However, the advantage in the form of low cost is offset by a large number of disadvantages. In particular, the foam itself is a rather brittle and soft material that is very easy to break. Even if you just squeeze such a product in your hand, it can deform.

Tree

Wooden ceiling skirting boards differ from analogues. Wood has a fairly large weight, which affects the mass of products from it. As a result, the skirting boards are quite dense, very resistant to mechanical damage and hard, which allows you not to be afraid of accidental deformation during installation or cutting.

Cutting skirting boards for ceilings without miter box

You also need to figure out how to glue a ceiling plinth without a miter box. this tool is far from always available. One of these methods involves marking the skirting boards on the ceiling. Perhaps the only drawback of this method is the fact that it is not very convenient to keep the bar motionless while applying the markings. Otherwise, the method is quite reliable. the measurement accuracy is higher, since when the plinth is applied to the place, all errors become noticeable.

Another method is associated with corner trimming of the baseboard. The edges of the two joining workpieces are cut at right angles. One of the planks is applied directly to the corner, after which a fishing line is applied to the ceiling along the contour of the plinth. The same operation is repeated with the opposite skirting board.

The point at which two separate mowing lines intersect is the point where the skirting board will need to be cut. The workpieces are in turn applied again to their places, on which the cut mowing line is marked. A straight line is drawn from the mark to the opposite edge of the part. The skirting boards are cut in accordance with the markings applied to them and are joined in place. This method is an excellent answer to the question of how to connect the corners of the ceiling plinth without a miter box, especially when it comes to internal corners.

Outside corner cutting

In the case of external corners, the cutting technology will look like this:

  • For greater accuracy, it will be better to start from the inner corners, and only then proceed to the outer corners. If this is not done, then the length of the plinth in the end may simply not be enough.
  • The part is attached to the ceiling, and marks are made on it in the right places. Then the plinth is placed in the miter box, held with the left hand near the near wall and cut off at the desired angle using a hacksaw.
  • The opposite bar is laid near the near wall of the miter box, but is held by the right hand. The hacksaw is at a 45-degree angle and the workpiece can be cut off. Finished planks need to be docked together to make sure the cut is correct.

How to trim the ceiling plinth in the corners? With and without miter box

For decorative finishing of ceilings when renovating houses and apartments, ceiling skirting boards (including flexible ones) made of plastic are used. Styrofoam, gypsum and wood. When installing them, the question necessarily arises of how to cut the corners on the ceiling plinth for internal and external joints, as well as to build them along the length.

This is possible when using a carpenter’s maker, a homemade marking device or without any devices. this and not only will be discussed below, as well as in the demonstration in this article.

DIY impromptu miter box

Making a miter box with your own hands is also not difficult.

You will need three wooden planks or boards, which must be put together in a U-shaped box. Then the necessary angles are marked on the walls of the box, and a cut is made with a hacksaw. As a result, you should get a wooden miter box, in which grooves are cut.

A combination of an impromptu miter box and a template with marked lines. For the convenience of cutting, it is necessary to build something in which it will be convenient to hold the plinth plinth, since it is difficult to keep it suspended. It is enough to put together a corner from two wooden planks or boards. On paper, you need to draw a mowing line with angles for cutting at 45 degrees or at any other. Then we apply the skirting board blank to the corner, press it by hand, as described in the technology for using the miter box, move the piece of paper with the template under the edge where we are going to cut, and cut it off. In the process of cutting, we focus on the line drawn on the paper.

As an impromptu miter box, you can use anything you want, anything. that we form a corner. For example, a table pushed against a wall.

Important! Pay attention to the measurement rule for trimming the ceiling plinth. To mark the inner corner, you need to measure the length directly from the corner itself. To outline the outer corner, it is necessary to be guided by the fact that the plinth will protrude deep into the room by a distance equal to its width.

It is not necessary to fix the plinths of the ceiling plinths before you cut the striker and try on their location. Only after the two strikers are perfectly aligned in the corner, you can start attaching them to the ceiling. Minor imperfections can be finished with a file or nail file in the case of wooden and polyurethane skirting boards. To fit foam products, you will have to wield a sharp knife.

If suddenly, even after adjusting the skirting boards, a small gap remains between them, do not despair, it can be repaired with a putty. Cutting the ceiling plinth yourself is not difficult. But in order not to spoil many products, it is better to pre-train on small blanks.

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 tray made of plastic, wood or metal with vertical slots for cutting at an angle of 90 ° and 45 °. There are also more complex miter box designs. for cutting at angles of 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 skirting board with a miter box. inner corner:

  • We apply the plinth to the ceiling, measure the required length.
  • Then we install the plinth strip in the miter box so that the position coincides with the position of the plinth on the ceiling.
  • The plinth strip must be pressed against the far wall of the miter box.
  • 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. After cutting, wooden skirting boards will most likely have to be adjusted with a file.

How to cut a skirting board 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 bar 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.
  • Cut off the workpiece.
  • Install the striker to the nearest wall, hold it with your right hand.
  • We set the hacksaw at a 45 degree angle when the handle approaches the right hand.
  • 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 plinth suspended during the cutting process. Otherwise, it is possible to mark the angle for cutting 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 ceiling plinth:

  • First of all, two workpieces must be cut at an angle of 90 degrees.
  • 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 pushing its end against the wall. We outline the line.
  • The point of 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 the skirting boards along the outlined lines, join them and apply them to the installation site. Please note that this method is easier to cut inside corners.

Using fittings

Corner fittings for plastic skirting boards

  • For all fillets made of plastic, special fittings are sold, which not only overlaps the docking point, but also acts as a coupling when connecting. In order to connect two profiles through such a corner, there is a certain instruction that regulates the length of the plinth launch into the groove of the connecting corner. So, the most optimal value for launching into the corner is 5 mm, but this value can be at least 3 mm and no more than 7 mm.
  • The plastic skirting board for the ceiling, when docked through the fittings, is cut strictly at an angle of 90⁰ and if burrs remain, they should be removed with a knife so as not to interfere with the installation. Some samples of such accessories have holes for attaching them to the wall, and some do not have such an opportunity, so they are held exclusively on profiles.
  • In addition to inner and outer corners, there are also end pieces, as well as profile extensions on long spans. Here again, similar fittings are used, only it performs slightly different functions. extension and plug. Trimming the launch is carried out according to the same dimensions: the optimal value of the profile section inserted into the fittings is 5 mm, but not less than 3 mm and not more than 7 mm.

Council. Installation of a plastic ceiling plinth is made with a slope, just not 45⁰, but less. To choose this slope correctly, you need to be guided by the docking fittings, that is, you should withstand exactly the slope that is formed when the fillet is connected to the fittings.

Internal and external corners without templates

Unfortunately, not all rooms have the correct 90, ⁰ angles and the template cutting of fillets leads to the creation of gaps, which then have to be repaired, and this does not always look good, especially on wooden products. A deflection of the wall even by one degree will lead to a very loose connection, but quite often such deviations are much larger. To do this, the markup is done without using any templates, factory or homemade, and below we will see how this is done.

Layout without template

In order to properly cut the corners of the ceiling plinth for an obtuse, even or acute angle, we need to attach the profile itself to the wall and ceiling at the slope with which it will be mounted, and rest it against the mating wall. On the ceiling, along the upper edge of the fillet, draw the fishing line and perform the exact same procedure on the other side.

The intersection of these lines (it is indicated in the photo by a red arrow) will be the upper cut point, and the lower corner of the fillet will be the lower point. Now when trimming a corner, you need to position the cutter so that the front to back angle is 45⁰ for the outer corner and 135⁰ for the inner corner.

If you use a joinery miter box, then such a trimming of the ceiling plinth in the corners is obtained automatically, but you cannot do without it, especially on internal joints, because the profiles, in addition to width, also have a thickness. If the foam products are flexible and soft enough to press the excess bulges, then for wood or plaster this is almost impossible, therefore, the more accurate the cut, the better the decoration will look.

Council. For the joint in the inner corner to look the best, it must be sealed. That is, fillets (with the exception of gypsum) are made 1-3 mm larger than the required size and the gaps overlap due to compression.

Cutting and mounting the outer corner

For joining fillets at the outer corner, a similar method is used. the profile is applied to the ceiling and to the wall in the mounting position and a line is drawn on the ceiling along its upper part. A similar operation is performed opposite and these mowing lines intersect. Please note that now the upper corner of the plinth has become sharp, and the lower one is obtuse, while for the internal joint it was the opposite.

With this method of marking, it is very important to correctly maintain the angle of the cutting tool in order to create an accurate ratio of the front and back sides of the profile, especially if its price is high and material overruns cannot be allowed.

For foam and gypsum products, small inaccuracies are not as terrible as for wooden ones, since the gap in the foam and gypsum is easily sealed with putty and it looks like a monolith. It is incomparably more difficult to close up gaps at joints made of wood, although it is also possible. for this, a special putty for wood is used.

Council. Docking fillets along the length is best done end-to-end, with an inclined cut. it is less noticeable this way. For wooden profiles, such a cut must be made not only oblique, but also oblique, so that one profile overlaps the other. This can be achieved if the bevel between the front and the wrong side is made 45⁰ or 135⁰.

We cut the ceiling plinth in the corners at home without a miter box correctly: Overview

A ceiling skirting board is a narrow decorative demarcation between the ceiling and 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 to correctly and accurately decorate a room with a ceiling plinth?

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

Factory ready corners

Note that every craftsman has the opportunity not to pore over precise cutting and fitting corners.

It is enough to measure the required length of the workpiece and cut it at right angles.

All defects and flaws will be hidden by this special element. But it is not always possible to use such a convenient method, since the standard dimensions of such factory corners can differ significantly from the size of the plinth itself.

Such angles will stand out for their disproportion, and it will not look very neat. But if the design of the room and the size of the blanks allow you to use this method, then you should not neglect it.

For those who have to use one of the methods of trimming the ceiling plinth, the following tips will come in handy.

How to make a miter box template with your own hands

If you don’t have a miter box, you don’t have to buy a one-time tool. You can make a template with similar functions yourself.

To do this, the required cut angles are applied to wood, paper or cardboard.

Then you need to draw a pair of parallel lines, find the center, and then use the protractor to measure the angles of any given value.

This method is especially convenient in that, using it, you can postpone an angle of any magnitude, even more than a straight line.

The technique of processing a baseboard blank using a homemade tool is practically no different from working with the original. The bar is pressed against one of the parallels, after which the hacksaw is set at the required angle and cut off.

Outside corner

It is most correct to observe the dimensions more accurately, first start to mark the inner corner, and only after that move on to the outer.

Otherwise, it may happen that the entire length of the bar is insufficient.

The plank is applied to the ceiling, basting is made to size. Holding on with the left hand, the ceiling plinth is pressed against the nearest wall, the hacksaw handle is brought closer to the hand. The workpiece is cut.

The strike plate is pressed against the nearest wall, while holding it with the right hand. The blade of the hacksaw should be at an angle of 45 °, the handle of the tool comes close to the hand of the master. A piece of the workpiece is cut off, the corner will neatly fit.

Such processing with the edge of parts with wort is good in cases where the angle between the walls is even and straight (90 °).

If its indicators leave much to be desired, then you should use a different method.

Ceiling plinth. fillet

To do this correctly, it is important to strictly follow the existing recommendations and rules for finishing work. And then the result will please you.

In order to hang the ceiling plinth, even inexperienced repairmen have no difficulty. They are worried about something completely different: how to cut the ceiling plinth correctly? In fact, almost every room, no matter how intricate it may be, is equipped with corners.

And in these inner corners, the individual elements of the skirting board should be nicely and evenly joined. And in rooms of a particularly complex configuration, you will have to be smart about the outer corners. Let’s try to figure out how to be in each of these situations, and how to cut the desired part using the available tools.

Pruning with a miter box

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

A miter box is a simple tool used by carpenters. It can be used to cut any workpiece at the desired angle.

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

There are complicated designs, on which, plus to the named corners, there is also a hole for making a 60-degree cut.

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

Ceiling markings

In all other respects, using this method, you will be able to mark the angle for cutting even more accurately than others.

When the skirting board is applied to the intended installation location, all dimensional deviations and inaccuracies are noticeable and immediately taken into account.
