When decorating the junction of walls and ceiling with a plinth difficult part work becomes its fit in the corners. Therefore, we decided to tell you how to cut the ceiling plinth correctly so that the junction is smooth and beautiful.

For this work, you will need a regular miter box, hacksaw blade corresponding to the plinth material, and a simple pencil. Skirting boards made of foam or polyurethane are easily cut with a construction knife with replaceable blades.

How to cut skirting boards with a miter box

The miter box is a trihedral box made of wood, metal or plastic, in two vertical sides of which through slots are made, located at an angle of 90 and 45 degrees (see). With the help of a miter box, it is easy to trim the ceiling plinth to join straight sections and form the correct right angles.

Internal corners

Standard rectangular room all angles are internal. The sticker of the plinth begins with them, so that you can ignore the length adjustment.

Advice. Before cutting off the ceiling plinth, decide which side it will adjoin the wall and which side - the ceiling. It depends on the relief of the product and its profile. If the plinth is not symmetrical, then its wider shelf is attached to the wall.

1. To cut the left corner, install the plinth into the miter box so that its long part is to your left, and the one you will cut is in the miter box itself, with a slight 45-degree approach to the right slot (see).
2. Press the part of the plinth that will be glued to the ceiling to the bottom of the miter box, and press the part to the wall against the side wall closest to you.
3. Holding the baseboard firmly in this position, cut a corner through the slot with a hacksaw or a construction knife.

1. Insert the second plinth into the miter box on the right and bring it to the left slot at 45 degrees.
2. Repeat the steps above.

After cutting the corners of both skirting boards, press them into the corner without glue to make sure the cuts line up. If this is not the case, then trim them with a construction knife. After this, the plinth can be glued.

Advice. Experienced finishers advise beginners to first fit and glue the skirting boards in all corners, and then paste straight sections between them.

External corners

External corners are found in rooms with internal ledges or niches (see). If you do not know how to properly cut the ceiling plinths in this case, then we hasten to reassure you. This is done in exactly the same way as in the previous case, with the only difference that the left plinth is cut through the left rather than the right slot of the miter box. That is, from a different angle.

As a result, the part of the plinth that will adjoin the ceiling will be longer.

We do the same with the right plinth: we put it into the miter box on the right, pressing it to the bottom and side wall, and cut it through the right slot.

Attention! When gluing the plinth to the outer corner, make sure that the edge of its lower part exactly matches the edge of the corner of the wall. If you have any questions, be sure to check it out. detailed video at the end of the article.

How to cut a skirting board if the corners are not straight

The corners in our apartments are very rarely exactly 90 degrees. And in houses of modern construction with bay windows and curved walls, they can be sharp, blunt, and rounded. In this case, the miter box will not solve the question of how to properly cut the ceiling plinths. What to do?

Adjusting uneven corners

1. Attach the plinth to the left wall close to the ceiling - as it should be glued. And with a simple pencil, draw along the top edge of the plinth, drawing a line on the ceiling.
2. Repeat this procedure, attaching the baseboard to the corner on the other side.

1. Now take two baseboards, and, alternately applying them to the corner on both sides, transfer the mark formed by the intersection of the lines to them.
2. Connect the mark to the opposite corner of the plinth.
3. Lay the skirting board on a flat hard surface, pressing it against it with the side that will be attached to the wall. And cut the corner with a construction knife along the drawn line, keeping it strictly vertical.

External corners are done in the same way.

There is another way to join skirting boards in the corners, without cutting the ends. To do this, you need to buy special corners that are simply glued into the corner, and the skirting boards themselves are attached to them on both sides with a factory cut.

Docking skirting boards in rounded corners

Most complex issue: how to cut the ceiling plinth correctly if the corner is rounded?

You will have to tinker to correctly cut off several pieces of 3-5 cm long from the plinth, depending on the radius of curvature. Then each piece will need to be cut on both sides so that its lower part becomes wider than the upper.

Attention! This should be done to design the inner radius. For the outside, on the contrary: the upper part should be wider.

Each such piece is glued into place only after fitting the next one to it.

Conclusion

We have tried to cover the task set before us in as much detail as possible. But still, we advise you to also see how to properly cut the ceiling plinth - the video on this page will help you figure it out in more detail.

Our advice: before you start work, practice on unnecessary scraps of skirting boards so as not to spoil the good material.

Installation of a ceiling plinth only at first glance seems to be a very simple task. In fact, you can encounter small and not very problems that can not only exhaust you, but also completely discourage the desire to make repairs. One of these problems is the joining of the ceiling plinth in the corners.

A lot of copies were broken by ordinary residents of apartments about the question of how to make the corner of the ceiling plinth, because it cannot simply be cut at an angle of 45 °. What to do in this case? Let's turn to professionals for advice.

How to make a corner of a ceiling plinth, how to properly join and cut a plinth

Yes, the main and most insidious nuance in the technology of installing a ceiling plinth is how to properly cut the plinth and dock it at the inner and outer corners. The point is that, unlike ordinary skirting boards, ceiling baguette it is attached to the base at an angle of 38-45 °, which is why it is problematic to make a classic 45 ° cut at the joints. WITH inside cut edges do not meet, leaving gaps.

But this is all complex professional lyrics. And how to make a corner of the ceiling plinth at home? The easiest way to work with foam accessories. First of all, measure the angle between the walls. If it is 90° or so, cut the edges at a 45° angle. Do the same with the second cut. With uneven joints between the walls and the ceiling, the radius of the corner is divided by two. Do not confuse the details with each other: the baguette that will be pasted on the left should have a cut on the right side, and the right fillet on the left.

To create an internal corner of the skirting board on the ceiling, its lower part must protrude above the upper one, for outer corner it's the other way around. Due to the soft and pliable texture, it is not necessary to fit polystyrene foam fillets to each other, but you will have to tinker with plastic or wooden ones. Having made side cuts, try on the planks to the ceiling and, if necessary, cut them in accordance with the direction of accession of the accessory to the surfaces.

After rough joining the ceiling plinths, screw or glue the fillets to the ceiling and wall, and then seal the seams.

How to cut the corners of a ceiling plinth, tools for trimming and cutting corners

To cut the corner of the ceiling plinth, you will need certain tools. If you want to make joints no worse than a venerable repairman, then an electric miter saw or miter box will be useful to you. With the help of these devices it is possible to achieve high precision cut. In this case, no effort is required. You just need to set the necessary parameters and lower the sharp saw blade onto a plastic or wooden surface.

You can also cut the ceiling plinth with more economical materials, such as a hacksaw or a hand miter box. A simple saw is very cheap, and it is extremely simple to work with it. The only drawback of such a device is rudeness. There is always a risk of spoiling the material. If you bought poor quality plastic or wood, then during operation the product may begin to crumble or delaminate into fibers.

Make an angle on ceiling plinth without burrs, a jigsaw will help. The advantage of this tool, in addition to high accuracy and efficiency, is also ease of operation. You can set the jigsaw in any direction of movement and make the highest quality cuts.

But these are all products that help solve the problem of how to join a ceiling plinth made of wood or PVC. To work with foam plastic, it makes no sense to use such a complex technique. An ordinary construction knife will do here. The main thing is that it has a well-sharpened blade, then you will be able to make a high-quality cut without tearing and delamination of the material.

You still have not decided how to cut the ceiling plinth? No problem. In stores you can find fillets already prepared for docking in the corners. In this case, the opposite principle applies. When working with such a skirting board, you need to make not oblique, but only straight cuts for the front connection of parts. True, the cost of such accessories is higher compared to the classic ones.

In order to start cutting the corners of the baseboard, you need to acquire such a tool as a miter box. This device adjusts the desired angle for cutting with a mounting knife or spatula. Its dimensions depend on the complexity of the work being done. For mounting plastic construction it is enough to use miter boxes with low inclinations up to 90 degrees. The most difficult moment here is, perhaps, the docking of all the elements so that there are no gaps between them. First you need to make a sketch. The plinth is placed directly on the wall. If the miter box is not at hand, you can get by with an ordinary stencil. The photo shows the process of cutting a small piece of foam with a knife.

How to make a corner on a ceiling plinth

In order to make a corner on the ceiling plinth, you need to get two important elements. This is the material with which you will glue the ceiling, as well as a measuring ruler with which you can measure the angles on the ceiling. If the wall is flat, then, as a rule, there are no special problems with measurements, but if there are gaps on it, then you can’t do without improvised means. It is better to pre-treat the corners with a sealant, sometimes it may need to be painted. It is important to remember that you first need to determine the angle of the product, and then carry out the following operations, such as, for example, cutting ceiling corner. On the diagram you see a hint on how to make corners correctly.

Ceiling baguettes

Ceiling baguettes - special decorative strips for the ceiling, which can be framed in various elements. Such a product can give the surface a beautiful aesthetic appearance. Most often, the baguette acts as a cornice and is used in theaters and other buildings of cultural education. However, now in stores you can buy its varieties for home use. Most often, the product acts as additional element. Its execution can be different, both the inner corner of the plinth and the outer corner of the plinth. Baguettes are recommended to be installed by experienced repairmen.
The figure shows one of the varieties of ceiling baguettes.

How to cut ceiling moldings in corners

In order to cut ceiling moldings in corners, you need to have a few important building materials with you and follow certain important rules:

1. With a pencil, measure the required length of the ceiling in which you are going to lay the plinth.
2. using a miter box, you need to measure the length to which you will lay the corner of the plinth and cut the corner.
3. make an approximate layout with length indications and cut it directly with a mounting knife.

Mittens can be purchased at any hardware store in your city.
In the figure, mark the area whose corner needs to be trimmed.

Ceiling fillets

Ceiling fillets are now gaining wide popularity due to their ease of installation. To proceed with the installation, you need to measure the perimeter of the room using a regular ruler. We divide the area by about 2, depending on the area of ​​\u200b\u200bthe room itself. You need to decide how many fillet strips you need to take. There are two ways to glue them: with glue or putty. In the first option, a flat surface of the wallpaper is required, for the second we cut the corners of the PVC plinth with a clerical knife, and then we strengthen the products with putty.

How to cut a ceiling plinth

In order to cut the ceiling plinth, you need to use a miter box. If you resort to professional repair, then you can buy the simplest option with a narrow range of corner radii, from about 45 to 90 degrees. In order not to be mistaken in how to cut the plinth, draw a layout. This can help, for example, when installing a plastic product. It is cut off already by the very edge of the miter box, if there are uneven edges, they are sawn with a mounting knife. In plastic baseboards, it is advisable to measure several pieces of stucco molding, and then deal with their separation. You can use a regular saw to cut the ceiling plinth.

What are the corners for the ceiling plinth

Corners for a ceiling plinth or, as they are also called differently, baguettes are special pieces of plastic that have decorative trim. In everyday life, you can still find such a name as ceiling cornices. Initially, they were used for decoration in buildings of cultural importance, but over time their use has expanded to simple finishes at home. For corners, it is also necessary to first measure the length of the ceiling. Corners are most often made of polystyrene and have a dense texture and structure. In order to install such baguettes, concentration and care are needed. Installation is slightly different from the usual ceiling finish.

Corners for skirting boards are various forms. Their main feature is decorativeness and protection of the outer corner.

How to dock a ceiling plinth

We will give you some tips on how to properly join the ceiling skirting boards. And it doesn’t matter if you have a narrow or wide ceiling plinth. In order to start joining each piece, you need to point one piece of foam plinth to the diameter of the wall and draw a line with a pencil to the other corner. This way you can measure the joint of the ceiling plinth and its gusset. Next, you need to attach the fillet directly to the corner (not to the mark!), And cut it with a regular clerical knife. For a successful connection, you should use bars with sandpaper. Corners are arranged directly in monolithic structure and one color.

What is a wooden ceiling plinth

Wooden ceiling plinth is a type of decorative ceiling finish that allows you to hide the visible irregularities of the wall and add attractiveness to your room. In addition to standard plastic products, there are also wooden ones. You can get them at the warehouses of logging plants, or in a regular hardware store. You should choose only the one that will match the decoration of your home. Be sure to purchase nails or screws to hold wooden cornice ceiling. Installing these elements takes some time, but the installation process itself is not as complicated as it seems.

It is necessary to carefully file the pieces, cut out the corners, and process the places of future joints. You will need various tools and fixtures for cutting wood. The docking technique is practically no different from other types of similar products. The main thing is to carefully read how to calculate and how to fit all the joints. Then the connection will pass without problems.

How to join skirting boards

In order to start the process of docking skirting boards, you need to prepare several tools:

1. measuring pencil;
2. docking stationery knife.

First, measure the length and perimeter of the ceiling and mark with a pencil. If your surface is flat, you can get a regular miter box. The device is used when laying skirting boards at small angles, approximately 90-120 degrees. One plank of the product is placed under the miter box and cuts are made with the help of a knife in order to form grooves for the layout. A docking clerical knife is used if the corners of the ceiling are not even.

What is foam plinth

Polystyrene has long established itself as a good construction material due to its ease of installation. For ceilings, it is the foam plinth that has found wide application. Such products are now readily available, and they can be bought in absolutely any building market. Polystyrene foam has good decorative properties. Such a skirting board is usually delivered in particles. To secure it, several items are used, such as a miter box, a clerical knife. In order to measure the length, you can do with an ordinary well-sharpened pencil

How to cut a corner for a ceiling molding

How to cut a corner? In order to proceed with the installation of ceiling plinths, you first need to know how to cut the corner of the ceiling plinth. Angles are measured using goniometers and a marking pencil, through which you can calculate which side of the corner we need to apply a piece. If we have a flat surface, we do it with a miter box at small angles, and then, using a clerical knife, we cut out the designated corners. If it's a plastic baseboard, you'll need to draw sample diagram in order not to make mistakes in joining elements. Circumcision must be done carefully

How to cut a skirting board

In order to know how to cut the baseboard during installation, you must have a miter box (for flat surfaces) or a clerical knife, which is used for uneven corners. If you have plastic product, it is best to use a special hacksaw for metal, then trimming will be much easier. It is necessary to cut the baseboard carefully, without pressing hard on the knife or saw, so as not to cut your hand instead of the corner of the baseboard. The miter box is used only for flat surfaces. The product is cut most often at small angles, at a distance of up to about 90 degrees. Stationery knife protrudes one-stop solution. When cutting, it is advisable to avoid places where there are gaps.

What is a miter box for a ceiling plinth

The miter box for the ceiling plinth is essential tool for processing skirting boards in the ceiling. It is distinguished by the presence of cutting tips on both sides at different angles from 45 to 90 degrees, which are located, as a rule, on the left and right sides. Using these tips, the plinth is clamped on both sides and sawn off cutting tool. In order to attach parts of the plinth, it is necessary to draw the necessary corners for joining with a pencil. The marked product is inserted into the miter box so that it stands steadily on its surface. The plinth is held with one hand, and the second, from the other angle, you need to cut the material.

How to glue a ceiling plinth

In order to know how to glue a ceiling plinth, you need to follow a few rules:

1. always start from the corners of the room, they are the easiest, and then you can proceed to the rest of the room (you need to glue the corners so that no gaps form);
2. with a plastic plinth for leplin, finishing putty is used.

Places for fastening are moistened with soil or plain water. After the putty has dried, it is recommended that the surface be sealed with cracks. For their smearing, sealants of various contents are used, but it is best to take the substance on acrylic base. For small room one pack is enough. Sealant installation is similar to putty.

The ceiling plinth performs not only a decorative function, visually separating the walls from the ceiling, but can also hide the joints of various finishing materials ceiling and walls. Not every interior design involves the use of a ceiling plinth, but most often general form the premises seem unfinished without it. In fixing this element - fillets - there is nothing complicated, almost all types of skirting boards are attached with glue. But the question of how to properly cut the ceiling plinth in the corners of the premises can confuse many. After all, even in simple room there are internal corners where the planks of the ceiling plinth need to be joined precisely and beautifully. And in a more complex configuration of the room, you will also have to dock the skirting boards, making the outer corner. In this article, we will look at various options how to cut a ceiling plinth with and without improvised tools.

First you need to deal with the question of how to cut the ceiling plinth, the answer to it depends on the material from which the fillet is made. On the this moment Ceiling skirting boards made of polyvinyl chloride (PVC), expanded polystyrene (styrofoam), polyurethane and wood are sold.

PVC ceiling moldings are the cheapest. Dents and creases are easily formed on them, which cannot be eliminated, so the product has to be thrown away. Also, their disadvantage is electrostaticity - the ability to attract dust. You can cut them with a sharp construction knife or a hacksaw.

Styrofoam ceiling moldings are also cheap. This material is very fragile, it easily crumbles during processing, therefore it is necessary to cut polystyrene foam with a sharp knife or a hacksaw for metal, without making too much pressure.

Ceiling moldings made of extruded polystyrene foam slightly more expensive than polystyrene foam, denser than them and more difficult to cut. However, they crumble less, so they are easier and more comfortable to work with. They are cut with a construction knife and a hacksaw for metal.

Polyurethane ceiling moldings are currently the most expensive. They are durable, elastic and moisture resistant, easily cut with a construction knife and do not crumble. The disadvantage of polyurethane baseboards is their dependence on temperature changes. For example, over gas stove the polyurethane baseboard will acquire residual deformations and begin to crackle slightly. If you try to process or cut such a plinth, it may bend or deform in another way.

Wooden ceiling moldings are dense, heavy products that can only be cut with a hacksaw, preferably with fine, frequent teeth. You can also use metal sheet.

Before moving on to listing ways to properly cut a ceiling plinth, I would like to note that it is possible not to cut a plinth with particular accuracy. Available for sale special corner pieces into which the edges of the plinth are inserted. In this case, it is enough to cut the skirting board at an angle of 90 °, and the corner element will hide all the flaws. But this method is not always used, since the dimensions of the corner elements are somewhat larger than the baseboards themselves, so the corners in the room will stand out against the general background. Sometimes it can look sloppy. However, if the design of the room allows the use of corner elements for ceiling plinths, it makes sense to use them. Further instructions useful for those who nevertheless decided to precisely cut the skirting boards at a given angle.

The miter box is a simple carpentry tool that allows you to cut the workpiece at the required 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 structures miter box - for cutting at angles of 90, 60 and 45 degrees. For more professional work, a miter box with swivel mechanism where the hacksaw can be fixed at any angle to the workpiece.

How to cut a ceiling plinth with a miter box - inner corner:

• We apply the plinth to the ceiling, measure the required length.
• Then we install the plinth bar into 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.
• Hold the plinth with your left hand.
• We choose such a position of the hacksaw when the angle is 45 degrees and at the same time 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 trimming the plinth striker. We also install it to the far wall of the miter box.
• Pressing and holding right hand.
• We choose a position for the hacksaw when the angle is 45 degrees and the hacksaw handle approaches the right hand.
• Cut off the plinth.

Next, we join the trimmed skirting boards and check the cutting accuracy. For a more accurate orientation, they also say that in order to make an internal corner, it is necessary to start cutting from the front of the plinth. Wooden plinths after trimming, most likely, will still have to be adjusted with a file.

How to cut a ceiling plinth with a miter box - outer corner:

• In order not to make a mistake 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 straps may not be long enough.
• It is necessary to attach the bar to the ceiling and outline the dimensions.
• We install the ceiling plinth bar and press it against the nearest wall.
• Hold with your left hand and select the position for the hacksaw at an angle of 45 degrees, when the handle approaches the left hand.
• We cut off the workpiece.
• We set the reciprocal bar to the nearest wall, hold it with the right hand.
• We set the hacksaw at an angle of 45 degrees, 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 leaves much to be desired, you will have to use other methods.

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

Marking the skirting board on the ceiling also allows you to cut the corner evenly and accurately. The only downside this method is that it is difficult and inconvenient to keep the skirting board suspended during the cutting process. For the rest, it is possible to outline the angle for cutting in this way even more accurately than in other ways. When applying the skirting board to the installation site, all wall flaws and deviations in the size of the corner are immediately taken into account.

Trimming the corner of the ceiling plinth:

• First of all, two blanks must be cut at an angle of 90 degrees.

• Then we first apply one plank, resting its end against a perpendicular wall. We draw a line on the ceiling, outlining the contour of the plinth.

• We remove this bar and apply the reciprocal bar, also resting its end against the wall. Let's draw a line.

• The point of intersection of the marked lines will be the mark at which the plinth must be cut.
• Again, we apply each bar in turn and mark the cut point on them.
• We draw a line from this point to the other edge of the plinth.

We cut off the skirting boards along the marked lines, join them and apply them to the installation site. Please note that using this method it is more convenient to cut internal corners.

Something resembling a miter box can be made by applying the necessary cutting angles to paper, cardboard or wood. It is necessary to draw two parallel lines, determine the center, and then set aside the necessary 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 with a protractor.

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

Improvised tray-miter box do-it-yourself

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

Method 1. You will need three wooden planks or boards that need to be hammered into a U-shaped box. Then, the necessary angles are marked on the walls of the box, and a cut is made with a hacksaw. The result should be a wooden miter box in which grooves are cut.

Method 2. A combination of an impromptu miter box and a template with outlined lines. For the convenience of cutting, it is necessary to build something in which it will be convenient to hold the ceiling plinth bar, since it is difficult to keep it on weight. It is enough to put together a corner from two wooden planks or boards. On paper, you need to draw lines with angles for cutting at 45 degrees or at any other. Then we apply the plinth blank to the corner, press it with our hand, as described in the technology for using the miter box, move the 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 paper.

Method 3. As an impromptu miter box, you can use anything, everything - that we form an angle. For example, a table pushed up against a wall.

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

It is not necessary to fix the strips of the ceiling plinths before you cut the reciprocal strip and tried on their location. Only after the two reciprocal strips have perfectly converged in the corner, you can begin to mount them to the ceiling. Minor flaws can be improved with a file or nail file in the case of wooden and polyurethane skirting boards. To fit the 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 putty. Trimming the ceiling plinth yourself is not difficult. But in order not to spoil a lot of products, it is better to pre-train on small blanks.

How to cut a corner on an indoor and outdoor ceiling plinth using a miter box

Have you decided to install a ceiling plinth (fillet, molding)? Do you want to hide the joints and get a finished look? While doing the work, you may encounter a lot of nuances. To avoid difficulties, you should figure out how to cut a ceiling plinth in the corners of internal and external, what is a miter box and how to make it. This is what we'll do.

Tools

When installing fillets, the question invariably arises of how to properly cut the slope of these decorative elements. To solve this problem, certain tools are used to do everything right:

• tape measure and pencil;
• hacksaw;
• ordinary or clerical;
• miter box.

The miter box is a popular, easy-to-use carpentry tool that allows you to cut the skirting board at the desired angle. This device is made of metal, wood, plastic. On the side walls, the device has vertical cutting slots made at an angle of 45, 60, 90 degrees.

Professional models are devices with a swivel mechanism that allows you to fix the file relative to the workpiece at almost any angle. Thus, the question of how to cut the ceiling plinth at an angle is greatly facilitated.

Trim the corners

At what angle to cut the ceiling plinth , depends on its location - it is external or internal.

Internal slope

Gouging an inside corner is done step by step in a certain order:

1. First you need to measure the desired length of the plinth on the ceiling.

1. Install the workpiece bar inside the miter box as it will be located on the ceiling.

For proper conduct work, it is necessary to place the plinth strip face up.

1. Press the workpiece against the far wall of the tool, holding it with your left hand.
2. The next step is to set the file at a 45 degree angle so that its handle is as close as possible to the left hand. The plinth should be cut without strong pressure on the saw.

1. Next, you need to cut the reciprocal bar. To do this, the workpiece is installed against the far wall.
2. We hold it with our right hand.
3. We turn the hacksaw at an angle of 45 degrees. In this case, the handle should be turned to the right. After that, you can cut off the plinth.

1. At the end of trimming, the inner corner of the ceiling plinth is checked by joining the planks.

Following this algorithm, you can do the job with millimeter accuracy. And the question of how to trim the inner corner will already be closed.

External slope

It is better to proceed to cutting the outer corner only after the inner one, because otherwise the molding may not be long enough.

To decide how to cut outer corner, it is necessary to act in a strictly defined way:

1. The first step, as in the case of the inner corner, is marking on the ceiling and applying the necessary marks to it with a pencil.
2. At the second stage, the plinth blank should be installed close to the near wall of the miter box.

1. Holding the bar with your left hand, turn the handle 45 degrees to the left with a hacksaw and cut off the baseboard.
2. To saw off the striker, you need to position it closer to the front wall of the fixture, holding it with your right hand. Saw off the skirting board at a 45 degree angle by turning the handle to the right.

1. After that, the cut pieces are joined together and, if necessary, the surfaces are trimmed, forming an external corner.

We make a miter box on our own

Sample

The template can be made using cardboard, wood or paper. The necessary markings are applied to these materials in the following form:

• first, two clear lines are applied in parallel;
• between these lines, a central point is determined and marked on paper;
• with the help of a protractor, the necessary angles are drawn, which can be more than 90 degrees.

It is important to consider the angle between walls and between walls and ceiling before using the template.

miter box

The manufacture of this tool can be done in different ways:

1. Of the three wooden planks or slats mounted U-shaped boxes. On its walls, grooves are marked and cut out at the desired slopes.
2. Two boards are knocked together strictly in perpendicular planes. A pattern is applied to the paper in the form of lines with inclinations of 45 degrees for cutting. The workpiece is applied to the corner, pressed against it by hand, as in the case of using a miter box, and the paper template is located on the opposite side. Cutting the fillet is carried out with orientation to the lines drawn on paper. When cutting a ceiling plinth, you can use anything that forms a right angle.

Other Ways to Trim Corners

It is most rational to use the miter box when the adjoining walls are strictly perpendicular planes. In other cases, these tasks can be solved by marking the plinth on the ceiling. This method allows you to take into account all deviations in the size of the angle, as well as uneven walls.

It is important to carry out the work in a certain order:

1. First, two blanks are cut along a straight vertical line.
2. At the next stage, it is necessary to attach one bar, resting it against a perpendicular wall with its end, and then do the same operations with the second bar.
3. Draw a line on the ceiling with a pencil.

1. The intersection point of the drawn contours will mean the mark along which the plinth is cut, forming corner in ceiling molding.
2. Then you should reattach each plank in turn and mark on them a cut line connecting its two edges.
3. The plinth is cut along the marked lines, after which its two parts must be joined and attached to the installation site.

With this method, it is important to consider two points: 1) it is more suitable for internal corners; 2) it is impossible to fix the fillets one by one without first joining and trying on their relative position. The remaining gaps between the two planks can be puttied.

Types of fillets

After we figured out the basic principles of corner trimming, I want to mention that fillets can be made from different materials:

• polyurethane;
• polyvinyl chloride;
• polystyrene (polystyrene);
• tree.

And so that you have an idea about each of them, and can choose the right part, I will briefly describe their characteristics:

• Polyurethane stucco is distinguished by its quality, strength, elasticity and resistance to moisture. Their main disadvantage is poor resistance to sudden temperature changes. Therefore, in rooms with high humidity I would not recommend installing such parts.

• Skirting boards made of polyvinyl chloride are distinguished by a favorable price. However, the material is capable of accumulating static electricity.

• Polystyrene fillets are resistant to moisture, have good quality and attractive appearance. However, under mechanical stress, they can break.

• Skirting boards made of wood - natural materials, but their disadvantage is exposure to moisture, high temperatures, as well as relatively large weight.

Also fillets differ in their length, width, shape, relief. Most often they are glued to ceiling joints to hide them. You need to choose a molding based on the type of wall and ceiling, the size of the room.

Now you know how to make a miter box yourself and how to make a clear corner on the ceiling plinth. By following the rules I have described, you can easily solve this problem. If you have any questions - ask them in the comments. A visual algorithm of actions will demonstrate the video in this article.

Repair is a responsible and costly undertaking. Although you can save a lot if you do the work yourself. Cosmetic finishing of premises is carried out according to certain technologies. You can decorate the interior using a variety of materials.

Today, a very popular technique is the use of ceiling plinths to hide irregularities between the walls and ceiling. In order for the contour to be aesthetic, it is necessary to do the work carefully. How to cut corners on ceiling moldings, tips will help you understand experienced craftsmen construction and repair business. They will tell you how to use various tools to perform the necessary manipulations with decorative finishes of various types.

General characteristics of the finish

When studying the question of how to properly cut a corner on a ceiling plinth, you should familiarize yourself with the features of such a finish. Stucco molding between the ceiling and walls is now made of artificial materials. It can be polyvinyl chloride, polystyrene foam or polyurethane. From natural materials wood can be used.

In the construction business it is called (scientifically) a fillet. Of all the materials from which such trim elements are made, polyurethane is considered the highest quality. Therefore, it is better to choose it. Next, let's try to figure out how to cut a corner. Expert advice will help you do this job well.

Skirting material

Experts agree that polyurethane is best material for the presented finishing products. But even it has a number of shortcomings. These should be taken into account before cutting corners on ceiling moldings. Polyurethane is subject to temperature fluctuations. Therefore, it is not used for decoration in the kitchen or bath. Otherwise, the skirting boards will quickly crack and lose their aesthetics.

Expanded polystyrene has almost all positive characteristics inherent in polyurethane. But it is still more fragile material. It's easy to break.

Skirting boards made of PVC are relatively cheap. But it is very easy to leave dents or potholes on them. Therefore, it is necessary to work with such products very carefully.

Wood looks very beautiful, but not in all interiors. In addition, it is quite difficult for an unprofessional master to work with such material. Would you like to do your own repairs? Then you better still choose polyurethane or expanded polystyrene.

Form, fittings

When studying the question of how to properly cut a corner on a ceiling plinth, attention should be paid to its shape and related products. There are embossed and smooth fillets. Their width and length can vary significantly.

When choosing the size of the skirting boards, the type of interior, as well as the height of the ceilings, are taken into account. For a small room, where the floor-to-ceiling distance is no more than 2.75 m, wide skirting boards will not work. They will look out of place. For the same reason, a narrow fillet should not be used for high ceilings. In such rooms, a 45 mm plinth looks good.

For installation, you can purchase curly corners from the same material as the fillet. They are external and internal. But quite often the skirting boards are joined without them, directly. In this case, it is required to perform an even, beautiful pruning corners.

Preparatory work

To make the process quick and easy, use a tool such as a miter box. This is a U-shaped template. There are slot patterns in its side walls. They have different angle tilt.

There is another technique that allows you to evenly glue the ceiling plinth. It is possible to cut corners without a miter box. But still, the use of such a tool greatly facilitates the work.

First you need to mark the plinth. If you want to create an external corner, measure the length along the ceiling, internal - along the wall. For fillets, a line slope of 45 and 90 degrees is used. Since this is a fairly small number of slot options, it is quite possible to make a template yourself. All you need is a sheet of paper or cardboard.

If the repairman has considerable experience in carrying out such operations, he can cut corners without additional tools. The master attaches the fillet to the wall, and then makes marks on the product right here. After that, he cuts off the excess. An inexperienced master, most likely, will not be able to cut even corners the first time. Therefore, it is better to use a miter box or close the irregularities with decorative corners.

Inner corner

First of all, it is necessary to consider the technique of how to cut the inner corner of the ceiling plinth. After all, they are in every room. If there are no external corners in ordinary rectangular rooms, then these varieties will have to be cut out anyway.

A plinth is placed at the bottom of the miter box with the side that will adjoin the ceiling. Bottom part fillet will be pressed against the wall of the tray.

If the material is hard, it is cut with a metal saw. Soft products are easily processed with a sharp knife. The angle should be 45 degrees. If the pressure during cutting is too strong, hooks and chips will form on the plinth. cut in the same way.

Before gluing, they are applied to the wall and, if necessary, adjusted small bumps. There should be no gaps between the skirting boards. If this is the first time such work is being done, you can practice in small pieces.

outside corner

Quite often, the contour of the walls in the room has complex shape. In this case, you will need to figure out how to cut the outer corner of the ceiling plinth. To do this, it is placed on the bottom of the miter box in the same way as in previous version, the side that is adjacent to the ceiling.

For these corners, other slots are used. They also have a slope of 45 degrees, but are on the other side. Further, after marking and trimming, 2 skirting boards are applied to the corresponding place on the ceiling. An adjustment is being made.

Difficulties may arise if it is necessary to cut the same plinth on one side for the outer corner, and on the other for the inner corner. This is where many make a mistake. First you need to cut the inner corner. Otherwise, a skirting board that is too short will not dock in any place.

Work without a miter box

Polyurethane looks very nice. How to cut corners on such a product so as not to spoil its appearance? And here the advice of experts will help the inexperienced master. Not always at home master at hand there is such a tool as a miter box. You can do without it.

To do this, the markup is performed directly on the wall. First, measure the required length decorative item. It is cut at a right angle. Next, apply each piece to the ceiling. They are outlined with a pencil. This results in an intersection. It is applied to both skirting boards.

From the point of intersection to the edge, draw an oblique line. This is the crop border. It is corrected before gluing by attaching both skirting boards to the corner. This is a fairly simple method, but even it requires a good eye and accuracy in work.

homemade tool

Don't have a chair? No problem! You can do it yourself. When cutting for the first time, it is better to use it in your work. This will require a plywood board, paper or cardboard.

Interested in how to cut the outer corner of the ceiling plinth, as well as its internal varieties, you need to adopt this approach. Two parallel lines are drawn on the selected material. Then, using a protractor, angles of 45 degrees are made along the edges.

A home-made tool is applied to the plinth, making appropriate notes. The pruning technique is the same. The miter box is not used if the walls in the room are very uneven. When creating an angle of 45 degrees, gaps between the joints are obtained due to such inconsistencies. Therefore, pruning is done in the previous way. Before installation, the edges must be corrected.

Embossed plinth

So, we already know how to cut corners on ceiling moldings. But we considered the procedure for performing work if available simple forms. Now you should pay attention to the relief varieties. Their installation is subject to increased requirements. Due to the presence of decorative elements, cutting such products is a little more difficult.

Docking of corners is carried out in those places where stucco or other volumetric elements protrude more above the surface. The angle is then expressive. It is better to take into account the components of the picture and crop it in the appropriate place.

The joints of volumetric ceiling plinths must be carefully glued. When working with relief products, it is allowed to use the tool listed above. It is allowed to make markings on the wall. But with the help of a miter box, it will be easier to cut voluminous skirting boards.

If you do the work carefully, the result will exceed all expectations. Having studied all the intricacies of the technique and figured out how to cut corners on ceiling plinths, you can begin to practice. Don't worry, the process will be easy and fast. This finish will fit into almost any interior. If all actions are performed carefully, gluing the joints with high quality, decorative effect will be amazing. The interior will please the eye for a long time.
