How to make the corner of the ceiling plinth with the help of a miter box and improvised means. Description of the process with photos and videos

There are more than enough tips on how to cut a skirting board at 45 degrees on the net, the only bad thing is that most of them are given by people who have never done this. Next, from a practical point of view, I will tell you how to cut skirting boards at the corners with your own hands in 3 options, and you will learn how to traditional ways, and about folk universal recipes.

The science of how to properly cut ceiling moldings in corners is not as complicated as it might seem.

A few words about tools and materials

Floor skirting boards are now made of wood or polyvinyl chloride (PVC), in other words, plastic. Ceiling fillets have a slightly longer list:

The range of ceiling plinths is much wider than that of the floor direction.

1. Polyurethane - these skirting boards have good elasticity and can bend around radial and other curved surfaces, but in any case, they need to be cut at clear angles;
2. Foam - the easiest a budget option, the price of foam skirting boards is low and they are very easy to cut;
3. PVC - the principle is the same as for floor skirting boards, but the lineup much wider;
4. Wooden - similar to the floor, only there are still wide models;
5. Gypsum - with the advent of polyurethane and foam, gypsum ceiling fillets faded into the background, firstly, they are heavy, and secondly, fragile. But in fairness, it's worth mentioning them.

How to cut correctly ceiling plinth and its outdoor counterpart is impossible without a good tool, let's dwell on this issue in a little more detail.

The best, almost ideal tool for cutting any skirting boards and not only is a miter saw with a rotary bed. The high-speed disc makes smooth and precise cuts, and the bed in these units rotates to any angle. The only problem is the serious cost of this tool.

A miter saw is almost the perfect tool for cutting skirting boards and more.

It is believed that one of the best hand tools for accurately cutting small bars is a backsaw. In principle, this is true, but I’ll tell you honestly, a really high-quality saw, even with the current assortment, is not easy to find. If you still decide to buy such a tool, then take a saw with a fine tooth.

Theoretically, foam and polyurethane can be cut with any sharp and durable knife. But at the same time, you need to have a steady hand and at least a little experience in cutting foam. Plus, cutting wide fillets with a knife is very problematic.

Without experience, making a clear cut with a knife is very problematic.

Personally, in the absence of trimming, I use only a hacksaw for metal. It is suitable for cutting absolutely any material, from foam to wood. By the way, the question is often asked how to cut a plastic plinth for the floor, and so - take a hacksaw for metal and you definitely can’t go wrong.

For cutting skirting boards, a hacksaw is considered one of the best tools.

Three ways to cut skirting boards

For floor and ceiling plinths, the cutting instructions are almost the same. But if on the floor a curved corner can be covered with something, then on the ceiling this is already a problem, so we will pay more attention to how to cut ceiling skirting boards.

Method number 1. Classic miter box

The classic miter box is a U-shaped bed with slots in the opposite sides. A part of a suitable size is inserted into this bed and sawn off with a hacksaw through the slots in the sides. The idea is not new, the tool is already several hundred years old, but, despite the simplicity, not everyone knows how to properly cut the corner of the ceiling plinth using such a miter box.

Not everyone knows how to cut a ceiling plinth in a corner using a classic miter box.

Tip: when trimming, ceiling plinths are applied to the side of the miter box that is closer to you, and floor plinths, on the contrary, need to be applied to the side of the tool farthest from you. This is not a dogma, but it is much easier to work this way.

It is easier to work with floor plinths, since the miter box lies on a horizontal plane, it is easier for you to navigate in the position of the plinth. People most often make mistakes when trimming a ceiling fillet; they are simply incorrectly put into the tool. There is a simple but important rule here.

Important: the edge of the ceiling fillet, which touches the wall, should be directed to the upper edge of the side of the miter box, and that part of the plinth that borders the ceiling is placed on the bottom of the miter box.

The corner, as you know, has 2 sides, so, in order to be less mistaken, accustom yourself to putting the bar that will be mounted on the right side of the corner into the miter box on the right, and put the bar that is attached to the left into the miter box on the left. Details about the intricacies of using a classic miter box are described in the video in this article.

In addition to the classic U-shaped miter box, there are two more types of similar structures - this is a professional and rotary tool. As for the professional version, only masters use it. The device is quite bulky, but it rotates at any angle and has a hacksaw that can be fixed in the desired position.

Professional miter box with the ability to fix a hacksaw and parts.

The swivel device can be safely called a "pocket" miter box. Of the advantages here, only the possibility of a clear fixation of the angle of rotation of the bar. On the one hand, it’s easy for them to work - I set the corner, attached it to the plinth and cut it off. But on the other hand, you need to get used to such a tool, if you do not have experience with a hacksaw, then you should not take a rotary miter box.

Tip: when choosing a classic U-shaped miter box, first of all, do not take Chinese products. And secondly, try to buy models with the ability to rigidly fix the part inside, one of these models is shown in the photo below.

A miter box with the ability to fix the part inside is much more convenient to work with.

Method number 2. Trimming according to the template

Most often, both ceiling and floor skirting boards need to be cut at 45º. If there is no specialized tool nearby, then an impromptu miter box can be drawn on a notebook sheet. From the school geometry course, we know that the diagonal of any square with respect to the base has an angle of inclination of 45º.

Next, you need to draw a square and draw 2 diagonals in it - these will be the desired 45º. You just have to correctly attach the plinth to the leaf and mark. True, in order to cut the plinth evenly without guides, you need a good eye and a faithful hand.

Method number 3. Applied universal

A 45º cut is a common option, but what if you need a different angle and only have a hacksaw and a pencil? It turns out that there is a very simple way out of this situation. Plus, this method is universal, it is suitable for both external and internal corners.

Moreover, I can assure you that those angles that visually appear to be straight, in fact, have deviations of a couple of degrees. As a result, you buy good tool, cut off clearly 45º, and when docking, the gap between the baseboards “crawls out”. Here this problem disappears. And then, using an example, we will consider how to cut the ceiling plinth in the inner corner.

Illustrations	Recommendations
	Stage 1. Take a fillet, apply it on one side of the corner and use it to draw 2 lines, along the wall and along the ceiling. Tip: to make the lines inconspicuous, they can be drawn not with a pencil, but, for example, with a nail or a knife edge.
	Stage 2. Do the same on the adjacent side of the corner.
	Stage 3. If you draw a diagonal from the intersection of the lines on the ceiling to the inner corner, then you will get the desired cutting line.
	Stage 4. Then take the tool and cut according to the finished markup. If you normally own a hacksaw, then the skirting boards should converge perfectly.
	. As I already mentioned, exactly the same technology can be used to trim the outer corner.

Important nuances

If you tried as best you could, but a small gap at the junction nevertheless “crawled out”, do not be discouraged. In wooden fillets, such a gap is easily smeared furniture wax. To cover the gap on the baseboards made of polyurethane, foam, plastic or gypsum, putty is perfect. Naturally, the color of the composition must match the color of the baseboard.

All cracks in the area of ​​\u200b\u200bceiling fillets are sealed with putty.

Wide ceiling fillets are certainly beautiful, but they can only be mounted on ideal smooth walls. If the plane of the wall in relation to the ceiling is a wave, then it is better to buy narrow polyurethane fillets, they are elastic and will smooth out this drawback.

Most of the questions arise about how to cut the wallpaper under the ceiling plinth. There is nothing complicated here: the wallpaper is glued with a slight overlap on the plinth, and when the wall is completely glued, take a large spatula, put it in a corner and cut off the excess with a knife.

But keep in mind - neither a knife nor a spatula can be torn off the wall until you have passed the entire plane. That is, they put a spatula from the corner, cut off the wallpaper along the length of the blade, and then without lifting the blade from the wall, move and cut until you reach the next corner.

Conclusion

All three methods I have described work, the choice depends on what tool you have available and what your professional skills are. If after watching the video you still have questions, welcome to the comments, I will help as much as I can.

If you are not confident in your abilities, then for both floor and ceiling plinths there are docking elements that allow you to do without trimming.

Sometimes you need to cut a particular part or product at a certain angle. As a rule, you need to cut baguettes, fillets, platbands, skirting boards and other similar interior elements at an angle of 45 degrees. Everyone can cope with this task. The main thing is not to rush, not to be nervous and everything will work out.

Buy ready-made corner elements

Of course, the easiest way is not to suffer with trimming a particular part, but to buy a ready-made one that does not need processing and trimming. Such parts and elements are sold today everywhere in large supermarkets or smaller stores.

For example, with regard to baguettes or fillets, they sell special corner elements that fit perfectly into the corner and do not need to be cut. They just need to be glued into place and pressed well.

The method of connecting platbands without trimming

Platbands today are often not cut at an angle, in order to then join each other, but make a joint at right angles. This method of connecting the platbands does not require any special trimming, which is very convenient. In addition, this method looks more modern and attractive.

Cutting at an angle with a miter box

If, nevertheless, it is necessary to cut this or that part at an angle, then it is worth stocking up with a miter box - the simplest device that looks like a small box. The miter box has slots that are designed for a saw or a long sharp knife. Of course, these slots are made in such a way that they form a smooth and precise angle of 45 degrees.

However, the miter box can have many slots at once, at different angles. This is convenient, because with the help of one device, you can cut any part at various angles.

There are adjustable chairs for sale. The slots in such a miter box can be adjusted, which allows the master to set exactly the angle that is required in this moment. In particular, it is quite simple to translate the slots of such a miter box into a position of 45 degrees.

Now the workpiece can be trimmed in an elementary way. A baguette, platband or plinth is placed in the miter box, after which a saw is inserted into the slots and the excess is simply cut off. The angle turns out to be perfect, exactly 45 degrees.

What to do if there is no miter box? Very simple. It is necessary to make a template according to which it will not be difficult to transfer the necessary markup to the blanks. As a template, you can choose thick cardboard or something else that would be appropriate in this case.

Trimming parts at an angle with a protractor

You can cut the part at an angle using a protractor. This is a measuring tool that is easy to use, and which is designed specifically to measure angles or make the necessary markings on certain parts. The protractor is applied to the part, mark the angle and make markings with a pencil. According to this markup, cutting the workpiece at the desired angle is not difficult.

Using Templates

If there is no protractor, miter box or ready-made corner elements available, you will have to look for a suitable template. Of course, the template must have the desired angle. It is applied to the workpiece and the workpiece is marked with a pencil. This is one of the most simple ways achieve the desired result.

Cut in place

Not always the walls, floor and ceiling will be perfectly even in practice. Most often they have irregularities. For this reason, there is no need to cut the workpieces at clear and precise angles, because they still will not fit perfectly.

Instead, it is sometimes convenient to cut the same ceiling plinth in place. That is, first they glue one plank of the plinth, cut it in the corner, and cut the second plank under it.

Of course, it is hardly possible to cut off the workpiece perfectly. However, if a small gap appears in the corner, it can always be covered with putty or gypsum plaster. Nothing special.

A skirting board is an integral element necessary for decorating a room and giving it a complete and neat look. It can be made from various materials, but plastic plinth is especially popular now. It is easy to install, but even in this process there are some subtleties that are important to know about. How to cut a plastic plinth correctly so that it can be neatly joined in the corners?

Previously, skirting boards were made mainly of wood and were considered precisely wooden products. But now in hardware stores you can find such decorative elements that are made from metal, plastic and other materials.

Wooden plinth is a classic. He is natural product as it is made from solid wood. This view is different high strength and durability - skirting boards, installed back in the days of the USSR, still serve faithfully in some apartments and houses. Now they are made mainly from pine wood, but there are also products from walnut, oak, ash and other species. However, due to this, the cost of products is growing - not everyone can afford such skirting boards.

Because of this, veneered skirting boards appeared on the market - their prices are an order of magnitude lower. However, outwardly, they practically do not differ from products made from expensive wood. The fact is that their upper part, which plays a decorative role, is just made of a thin layer of expensive wood. Without certain knowledge and experience, it is almost impossible to distinguish a veneered plinth from an ordinary wooden one.

On a note! For cutting skirting boards - wooden and veneered - an ordinary hacksaw is used for wood.

Plastic plinth, that is, made of PVC, is especially popular now. It partially replaced the conventional wooden crafts from the market, as it has a number of advantages:

• looks beautiful and neat - able to imitate natural wood products;
• easy to install, flexible and very easy to cut;
• can serve as a cable channel for laying wires;
• is not afraid of exposure to water, and also does not rot, mold does not start on it;
• It is inexpensive compared to wood or veneered products.

The plastic plinth is made of polyvinyl chloride, which is passed through special molds under high pressure. After solidification of the mass, a neat plastic product is obtained.

On a note! Some manufacturers decorate the edges of plastic baseboards with rubber. This measure helps the product not to slide on the walls and floor during installation and to fit snugly to the surfaces.

There are several types of plastic skirting boards - for example, used for carpet(have a special shape in the form of the letter G, fix the material) or for linoleum. There are also universal products that can be installed on any type of floor covering. They can also be classified according to hardness.

Table. Types of plastic skirting boards depending on the rigidity.

How to cut the corners of a skirting board

Since during repairs it is more and more often used precisely rigid plastic skirting boards, then it is about them and will be discussed. Their installation is inevitably associated with the need to cut and form beautiful joints in the corners. On how the plinth is joined, in general, the quality of all work and appearance rooms being renovated.

Methods for cutting plastic skirting boards

Cutting a skirting board is a seemingly simple, but responsible task. If the corners are cut incorrectly, they will not fit properly and all work will go down the drain, since the product will no longer have beautiful view- there will be gaps between the two sections of the plinth and decorative inserts (corners, docking elements, etc.).

Most often, for cutting the plinth, the usual hacksaw for metal which has small teeth. However, it is not suitable for thin baseboards, as the product will simply tear under the influence of this tool.

Sometimes the plinth is cut and scissors for metal. But the method also has its drawbacks, because the product can be crushed under the pressure of the blades. Less often, but still used and grinder. However, the cutting line after it can be sloppy, as the tool often "tear" soft plastic. Especially often this method is unsuccessful for beginners in the world of repair, who still do not know how to fully control the work. So the grinder can be attributed to rather specific methods.

On a note! To cut a thin baseboard, you can use a sharply sharpened knife or a clerical knife. But such work requires some skill, so it is recommended that you first practice on scraps of an old plastic baseboard.

The most important thing in the process of cutting the plinth is the observance of the required geometry. The procedure is never performed "by eye", the accuracy of measurements and accuracy are important here. Therefore, there are other methods for cutting skirting boards.

Stencil cutting

The method is recommended for cutting products intended for installation in non-standard rooms with angles that differ from the standard mark of 90 degrees. Stencils of the desired angle can be made from paper or thin cardboard. First, strips are cut from the rough material, which have exactly the same width as the baseboard. Then they are applied to the corner and fixed, after which they are cut to the shape of the corner. Then, according to the obtained stencils, the plinth itself is cut off at the required angle.

Cutting floor plinth with a miter box

For correct pruning plinth, a special device was invented, which was called miter box. It is a small bar with a recess for the plinth and with gaps located at different angles - for cutting tool.

With the help of a miter box, you can get neat and even cuts. The plinth is fixed inside the product, then the desired angle and direction of the cut are selected in a particular case.

On a note! If it is necessary to form a beautiful angle with the help of a miter box, then one piece of the plinth is cut at one angle, and the second - in a mirror image.

When working with the miter box, it is important to ensure that the edges of the plinth protrude beyond the edges of the selected slot for a small distance. If the cutting tool is wider than the baseboard itself, it is recommended to securely fix the product inside the miter box before cutting. Otherwise, the plinth can move inside, the cut angle will constantly change, because of which it (the cut) will turn out to be incorrect and incorrect.

Important! During cutting, the pressure on the baseboard should be moderate. Otherwise, it may break.

Using a ruler and pencil in the absence of a miter box

If there is no miter box at hand, and you don’t want to make stencils, then you can try to apply the necessary markings on the plinth with a pencil. In the case of the formation of an internal corner, the width of the product is measured with a ruler, then the resulting value is deposited on the end of the plinth, and from its corner to this marked point a line is drawn with a pencil, along which the cut will be made. The second plinth, which will form a corner together with the first, is simply cut off along the first one attached to it.

Important! If the installation of skirting boards is carried out in a room with complex geometry, then all angles will have to be carefully measured in order to avoid a mistake.

Experienced craftsmen recommend starting the installation of the plinth from the inside corner. At the junction of two walls, which form the inner corner, the cut on the baseboards will be equal to 45 degrees (in a room with correct and accurate geometry). Cutting is recommended to be done with a miter box - this is the only way to achieve a perfectly even cut.

Advice! If necessary, you can slightly adjust the skirting boards to each other using a grinder or rasp, slightly “removing” their edges.

In general, in any case, the cut edges of plastic skirting boards should be sanded - this way you can get rid of sharp edges, and it will be easier to work. And cutting skirting boards with cable channels is carried out only after disassembling the product - a decorative strip designed to hide wires and attachment points of the skirting board is cut separately.

It is recommended that immediately before installing the skirting board, cut the pieces to the required length and shape the corners so as not to be distracted by this procedure during the assembly of the skirting board. Do not neglect the use additional elements- plugs, corners and other products for plinth. With their help, it will be possible to give the finished work a finished and harmonious look.

Advice! If the corners where the plinth is laid and joined are uneven, then even decorative caps and other elements can be trimmed if necessary.

How to cut a plastic skirting board

If the angle in the room where it is planned to finish the joints of the walls and the floor with a plinth is 90 degrees, which happens extremely rarely, then the cuts of the plinths should each have an angle of 45 degrees. Such a cut is the easiest to make, especially with the use of a miter box. It is enough to insert the plinth into the miter box, then select a groove of 45 degrees and make a cut.

However, such angles of 90 degrees in rooms are extremely rare, usually they differ by several values ​​in one direction or another. And in some rooms, the corners may even be larger. Then the cutting is done in a different way: markings are drawn on the floor with a pencil, where on one and the other side of the corner the border of the plinth is drawn - you get a small rhombus. The diagonal of this rhombus will be the very cutting line of the product. Next, a plinth is applied to the markup, on which the markup is performed in accordance with the diagonal of the rhombus. If you draw a straight line from this mark to the corner of the plinth, then you get the very desired cutting line.

The outer corners of the skirting boards are formed a little differently, or rather, in a room with ideal geometry, you can also cut products at an angle of 45 degrees (but in a different direction) and, after joining, close the edges with a plug. Non-standard corners are cut as follows: one of the skirting boards is applied to one of the walls, its borders are marked with a pencil. The same procedure is carried out with another product - again a rhombus flaunts on the floor, the diagonal of which will become a guideline for cutting products.

Skirting board cutting instructions

Consider how the plinth is trimmed with a miter box and a hacksaw.

Step 1. After all measurements have been taken, the plinth is placed in the inner part of the miter box and pressed against one of its walls.

Step 2 Using a hacksaw, the plinth is trimmed. The cutting (sawing) tool is inserted into the selected groove - a cut is made.

However, sometimes it is enough to cut plastic skirting boards at a right angle - now it has appeared on sale a large number of various additional products for them. For example, there are such corners that will allow you to hide even cuts and decorate everything beautifully. Your attention - instructions for installing a plastic plinth.

How to fix the plinth? The answer is here!

In general, all existing methods of attaching skirting boards can be divided into two categories - installation by attaching to the floor and mounting to walls. You will have to choose depending on the type of skirting board and the design features of the living space. Read more in.

Step 1. All measurements are taken - the required length for the plinth segments is determined. These values ​​are deposited on two products from which corners will be formed.

Step 2 Skirting boards are cut with a miter box and any cutting tool and applied to the walls - this is necessary to make sure that the products are cut correctly and have the required length.

Step 3 If everything is done correctly, then the skirting boards are screwed to the wall using self-tapping screws and dowels. But before that, plugs or corners are put on their ends.

Step 4 At the outer corners, the plinths are interconnected with special plastic devices.

Step 5 The plinth is installed in its designated place and screwed to the wall with self-tapping screws.

Step 7 The cable channel with laid wires is closed with a decorative plug.

Step 8 External corners are closed with special corner plugs, which are simply put on the edges of the skirting boards that form the corner.

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

What is it made of and what is it called

The very first skirting boards on the ceiling were made of gypsum. They were cast in special molds, then they were installed on the ceiling on the mortar. Such curly ornaments were called fillets. Today you can see them infrequently: they are expensive, and outwardly they are almost no different from cheaper options. And the name is almost lost.

The most popular today are ceiling plinths made of polyurethane or polystyrene. They are inexpensive, look great, are easy to install, and have a wide range of profiles and patterns. The width can be from 5 mm to 250 mm. They are used in almost any room, decorated in any style. Exception - Wooden products are most often used here - style dictates its own terms.

There is also a similar finish made of plastic. It is mainly installed in bathrooms. But even in damp rooms, you can safely mount polyurethane strips - they are not afraid of dampness.

Cut the ceiling plinth in the corners of any material using one of the methods described below. The only exception is plastic skirting boards: you can make such an angle only using ready-made corners.

What and how to cut

Working with skirting boards different material implies the use different instruments for cutting. When working with a ceiling plinth made of wood, it is more convenient to work with a wood saw. All the rest, including plastic, foam and other polymers, are better cut with a metal blade. It turns out a more even cut, less burr. Saws are usually used when working with a miter box.

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

In general, in order to get used to the tool and material a little, take some piece and practice on it: cut, saw, cut. So at work there will be less problems.

How to get the right angle

Most of the problems when working with ceiling plinths arise when making corners. Since the surface of the products is complex, simply cutting at the right angle will not work: you also need to cut them so that they fit together and preferably without large gaps. In fact, there are several ways to make the corner of the ceiling plinth perfect (or almost).

Using a chair

If the corners and walls in the room are even, you can use a special carpentry tool - a miter box. This is an inverted U-shaped chute with lines for 90° and 45° cuts. The part in which you want to make a wash is laid inside, a saw is inserted into the guides. The part is held in place, cut at the required angle.

In the case of skirting boards, everything is not so simple: they must simultaneously adhere to two surfaces, therefore they must be pressed against one or another wall of the miter box. When working with ceiling, they are pressed against the side closest to you.

The sequence of actions when finishing the outer corner you need to make washed down at an angle of 45 degrees. Put the chair in front of you. Try on how the plinth will be located, determining which part of it will be attached to the ceiling. In order not to get confused and cut the ceiling plinth correctly, lay the plank that will be located on the right on the right, the one on the left - on the left.

With the part that is on the ceiling, press it to the bottom of the miter box. The other side is closer to you and raised. You lean it on the wall of the fixture so that it does not stagger when cutting. That is, the front part of the plinth is turned away from you. Make the cut direction as shown in the photo below. Putting the two cut parts together, you get a protruding - outer or outer corner.

How to make an outer corner of a ceiling plinth using a chair

The sawn off parts are first applied to the place “dry”, without applying glue. If the geometry of the corner turned out to be not so ideal, you can tweak it a little with a knife. Small errors are easier to cover with a special putty.

FROM inside corner ceiling plinth situation is very similar. First, try on which side will be on the ceiling, press this part to the bottom of the miter box, rest the second part on the wall closest to you and make cuts as shown in the photo below.

And again, first try on without applying glue, if necessary, slightly adjust. Then apply a thin bead of adhesive to both surfaces that will be attached to the wall or ceiling.

Your version of how to properly use the miter box is shown in the video.

How to make a corner of a ceiling plinth without a miter box

Few people in apartments or houses have exactly 90 ° angles. Small deviations are easily corrected after fitting. But not always. Then you have to mark everything "in place" - under the ceiling.

You will need a finely defined pencil (hard - it is not so visible on the ceiling, but leaves fairly clear marks close up), a small piece of plinth, a ruler and a good stationery knife if you work with polyurethane (polystyrene) baguettes or a metal saw to work with the rest of the materials.

Apply the plinth to the corner, draw along the outer edge with a pencil. Apply to the other side of the corner, also note. You have a cross on the ceiling, the center of which marks the place where the strips of the ceiling plinth should meet (see photo). Having installed a segment of the plinth in the corner, which will be glued there and resting it with its end against the wall, transfer the mark to it.

How to make corners on ceiling plinths without using special tools

Now take a ruler and connect the edge of the plinth with the marked mark. If you just put the plinth on the table and cut along the line, the two parts in the corner will still not add up: the inside will interfere. It can be trimmed later, trying on the ceiling. The second way is to set the piece to be cut on the table with the piece that will be on the ceiling. And cut along the line, but holding the knife at an angle of about 45 °. You will still need to correct, but much less (and less likely to make a mistake).

Repeat the same operation with the second bar. Attach to desired wall, rest the end against the adjoining wall, mark the place where the cross is drawn, draw a line and then cut it off. Correction is carried out "dry" without applying glue.

You repeat exactly the same actions for the outer (protruding) corner. Now you know another way to make a corner of a ceiling plinth, and without a string or other special devices.

With decorative corners

There is another, the easiest way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory decorative corners. They are installed in a corner, the strips are glued closely to them. Cutting them if necessary is very simple: a few millimeters with an ordinary clerical knife.

How to join in corners

If the installation of the first corner is completed, we can assume that you have already learned to do almost everything. “Almost” because you still need to learn how to connect the corners and cut the planks to length. When some part is already glued and there is a small distance to the corner, how can one not make a mistake with the length? The answer is simple: leave a margin.

At first, you can cut off a piece 10-15 cm longer: there will be an opportunity to redo it several times if something does not work out right away. Then you make a corner in the way described above, try it on dry, adjust everything so that the result suits you. Only after that you can put the already cut bar into the corner and mark the place to which it can be shortened. You need to cut exactly at 90 °. It is not necessary to use a stool. Just try to put the knife (hacksaw) perpendicular to the surface.

This tool is a profile in the form of an inverted letter P. On the sides there are slots in it for sawing at an angle of 45, 60 and 90 degrees. More complex corner templates or miter boxes have devices for setting different sawing angles.

For the inexperienced master the best option will be the purchase of a finished miter box in a hardware store. At home, it can be made from three planed boards or plywood.

The tool can be assembled by fastening together pre-prepared parts. The corner template box must be secured with wood glue or screws. The side walls of the miter box must be strictly parallel to one another. The horizontal bar must create a strict perpendicular with the side ones.

Step 3: Mark cuts at different angles for sawing laminate, architraves, etc.
