How to properly cut a wide ceiling plinth. How to cut ceiling plinths in corners. Joining skirting boards at non-standard angles

At first glance, installing this decorative element does not present any difficulties, but in reality and in self-installation Beginners may have some difficulties. One of the main ones is cutting skirting boards to decorate the corners of the room. If cut incorrectly, the plinth will not only not decorate the room, but can also completely ruin it appearance.

How to avoid additional difficulties, correctly and with least losses cut the corner and install this beautifully necessary element interior?

What do you need to know to prepare for work?

The most common options for ceiling plinths are products made from polystyrene foam, extruded polystyrene foam and wood. Depending on the material, preparations are made for installation and cutting of corners, and selection of cutting equipment.

For example, foam products are cut with a regular stationery knife. For cutting denser polystyrene foam, use a well-sharpened construction knife or a hacksaw for metal. Despite its density, this material crumbles very easily, and therefore when working with it you should not press hard on the tool.

As for the most durable wooden baseboards, they are cut with a hacksaw with frequent fine teeth.


Also, when cutting plinth material, you will need a miter box - a tool that helps cut the plank at a given angle.


The main assistant here is a miter box. It is also worth keeping in mind that corners can be internal and external. The first are the usual corners of any rectangular rooms. The latter are formed in niches and other original designs.

So, to form an internal corner, you need to install a piece of plinth in a miter box and press it against its far wall. In this case, you need to hold the workpiece with your left hand. The hacksaw is installed so that the cutting angle is 45 degrees, and the saw handle is directed towards the left hand.


To trim the second (counter) part of the corner, all actions will be similar, only the workpiece will need to be held right hand and the handle of the hacksaw will be directed towards it. Small inaccuracies can be removed with a file.

In the case of preparing fillet for external corners, the algorithm of actions remains almost unchanged. The only difference is that the bar is pressed not against the far wall of the miter box, but against the nearest one.


It is important to remember that this option for adjusting angles is only applicable when the room angle is 90 degrees. If the room angle is not straight, then its radius is divided by two, and thus the required cut slope is determined.


The miter box can be purchased or made independently. Moreover self-production this the necessary tool does not require high costs and a lot of time. By connecting three boards with a width of 10 to 15 cm, a box is formed, on which, after careful measurements, the appropriate markings are applied. To do this, two perpendicular lines are drawn on the edges of the sides.

Then a distance equal to the width of the workpiece (box) is removed from them and two more marks are applied. All marks should eventually form a square. In the designated places, cuts are made diagonally, which are then expanded using sandpaper.


Another method of forming a fillet angle is using ceiling markings. In this case, the angle will exactly correspond to the wall joints. This is a plus. The downside is the inconvenience of holding the material in a canopy when cutting.

To properly cut the plank, first take one of the baseboards and place it firmly on the intended installation site. A small straight line is drawn along it on the ceiling surface. Then take another block and press it on the other side of the corner. And again they draw a segment.


After this, taking the first plank again and leaning it the way it will look in its finished form, mark on it the place corresponding to the point of intersection of two straight lines on the ceiling. The resulting mark is connected by a line to the opposite edge of the plinth. This creates a cutting line.

For the second part of the corner fillet, the procedure is repeated. The result is two planks that form the required angle.

There are now more than enough tips on how to cut a baseboard at 45 degrees on the Internet, 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 Trim Properly ceiling skirting boards in corners is not as difficult as it may seem.

A few words about tools and materials

Floor skirting boards are now made of wood or polyvinyl chloride (PVC), in other words, plastic. For ceiling fillets, the list is a little longer:

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

  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 trimmed to precise angles;
  2. Foam plastic - the simplest 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 floor ones, only here there are also wide models;
  5. Gypsum - with the advent of polyurethane and foam plastic, gypsum ceiling fillets faded into the background, firstly, they are heavy, and secondly, fragile. But to be fair, they are worth mentioning.

Since it is impossible to correctly cut the ceiling plinth and its floor counterpart without a good tool, we will dwell on this issue in a little more detail.

The best, practically perfect tool for trimming any skirting boards and more - this is a miter saw with a rotating 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 an almost ideal tool for cutting baseboards and more.

Considered one of the best hand tools for precise cutting of small bars - this is an abrasive saw. In principle, this is true, but I’ll tell you honestly, it’s not easy to find a really high-quality saw, even with the current assortment. If you 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 firm 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, if I don’t have a crosscut tool, I only use a hacksaw. It is suitable for cutting absolutely any material, from foam to wood. By the way, people often ask the question of how to cut a plastic baseboard for the floor, 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 working methods for trimming skirting boards

For floor and ceiling skirting boards, the cutting instructions are almost the same. But if on the floor a crooked 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 the ceiling plinths.

Method number 1. Classic miter box

The classic miter box is a U-shaped box with slots in the opposite sides. A piece of suitable size is inserted into this stock and sawed 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 its simplicity, not everyone knows how to correctly cut the corner of a 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 closest to you, and floor plinths, on the contrary, should 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 orient yourself in the position of the plinth. Most common mistakes people make when pruning ceiling fillet, it is simply inserted incorrectly into the instrument. There is a simple but important rule here.

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

As you know, a corner has 2 sides, so in order to make fewer mistakes, train yourself to place the bar that will be mounted on the right side of the corner in the miter box on the right, and the bar that is attached to the left in the miter box on the left. The intricacies of using a classic miter box are described in detail in the video in this article.

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

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

The rotating device can easily be called a “pocket” miter box. The only advantage here is the ability to clearly fix the angle of rotation of the bar. On the one hand, it’s easy to work with - set the corner, apply it to the baseboard and cut it off. But on the other hand, you need to get used to such a tool; if you do not have experience working with a hacksaw, then you should not take a rotary miter box.

Advice: when choosing a classic U-shaped miter box, first of all, do not buy 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 a template

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

Next you need to draw a square and draw 2 diagonals in it - this will be the required 45º. All you have to do is correctly attach the plinth to the leaf and mark. True, in order to cut the plinth smoothly without guides, you need a good eye and a steady hand.

Method No. 3. Applied universal

Trimming at 45º 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 seem straight, in fact have deviations of a couple of degrees. As a result, you buy good tool, you cut off exactly 45º, and when joining, a gap appears between the baseboards. Here this problem disappears. And then, using an example, we will look at how to cut the ceiling plinth in the inner corner.

Illustrations Recommendations

Stage 1.

Take the fillet, place it on one side of the corner and use it to draw 2 lines, along the wall and along the ceiling.

Advice: to make the lines unnoticeable, they can be drawn not with a pencil but, for example, with a nail or the tip of a knife.


Stage 2. You do the same on adjacent side corner.

Stage 3. If you draw a diagonal from the intersection of the lines on the ceiling to the inner corner, you will get the desired cutting line.

Stage 4. Next, take the tool and cut along the finished markings. If you are comfortable with a hacksaw, then the baseboards should fit together perfectly.

. As I already mentioned, you can trim the outer corner using exactly the same technology.

Important nuances

If you tried your best, but a small gap at the joint still “came out,” do not be discouraged. In wooden fillets, such a gap can be easily covered with furniture wax. To fill a gap on baseboards made of polyurethane, foam, plastic or plaster, putty is perfect. Naturally, the color of the composition must match the color of the baseboard.

All cracks in the area of ​​the ceiling fillets are sealed with putty.

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

The most questions arise about how to cut wallpaper to fit the ceiling plinth. There is nothing complicated here: the wallpaper is glued with a slight overlap on the baseboards and when the wall is completely glued, take a large spatula, place it in the corner and cut off the excess along the blade with a knife.

But keep in mind - neither the knife nor the spatula can be removed from the wall until you have gone through the entire plane. That is, you put a spatula from the corner, cut 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 described work; the choice depends on what tool you have and what your professional skills are. If after watching the video you still have questions, welcome to the comments, I’ll help in any way I can.

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

At first glance, installing a ceiling plinth may not seem like such a difficult task to us. But, alas, this is far from the case. In fact, during repairs, problems of various kinds may arise that can completely rid you of the desire to do the repairs yourself. Joining ceiling plinths in the corners can be one of these difficulties. Many apartment owners who decided to carry out renovations puzzled over how to install the ceiling plinth. However, it is completely unacceptable to simply cut it at an angle of 45°. And only masters of their craft can help out with practical recommendations in solving this problem.

How to properly cut skirting boards and make corners and joints in the corners?

Incredibly scrupulous and very significant feature The specifics of installation lie in how to precisely trim and arrange it in all available corners. In fact, if you compare the baguette with an ordinary baseboard, it is equipped with respect to the base at an angle of 38-45 degrees. The generally accepted 45-degree angle cut at joint areas is sometimes very difficult to implement. When connecting ready-made edges with inside As a rule, gaps are likely.

Excellent results when cutting plinths are possible if the cut is made not only along the outer edge, but also from the outer side (if the work is carried out with outer corner– an internal slice is added). Information on how to cut the corners of a ceiling plinth can be found in more detail using the video. The master carried out the cutting using a special miter saw. If you don't have it at your disposal, then home tool is also quite applicable for such a process. After the cut is organized, the texture of the cornice should be clearly visible on the back or front part.

How to properly cut a ceiling plinth with your own hands without the help of professionals?

Foam components would be more preferable for installation. They are a little easier to work with. First of all, you need to organize work on measuring inter-wall angles. If their value is close to 90°, then cutting the edges at an angle of 45° is required. This action must be done with the next trim. If the inter-wall joints are represented by any irregularities, then the radius of the corner is divided in half. Try not to confuse the parts: the baguette, the one that is fixed on the left side, should be equipped with a right cut, and the right fillet with a left one.

To make an internal corner, you must try to make sure that its lower section rises above the upper, and for an external corner - the opposite. Plastic and pretty soft structure polystyrene foam fillets eliminate the need to adjust them to each other, which can hardly be said about components made of wood or plastic. After working on the side sections, you need to estimate the plank to the ceiling for fitting. If necessary, cuts are made in the area where the base and accessory join. The work of rough joining the skirting boards is completed by fixing them with glue or screwing the fillets to the walls with further sealing of the seams.

How to correctly cut the corners of the baseboard, the tool used for cutting and trimming the corners?

To cut the corners of the ceiling plinth, it is recommended to work with a specialized tool. For installation of joints on professional level An electric miter saw or miter box can come to the rescue. With this toolkit high accuracy cutting will be ensured. You don't need any special effort for this. You just need to set the required parameters and start working with the saw blade. Among the least expensive methods, it is worth noting the choice of a hacksaw or hand miter box. Simple has a low price. But getting along with her is quite easy. The instrument is very crude. This is perhaps the only drawback. If used carelessly, the material can be damaged. Therefore, it is not worth saving on it. Having purchased material from low-grade wood or plastic, there is a risk of delamination into fibers. If you are using polystyrene foam, a saw is not required. A construction knife is quite suitable for this. Its blade must be impeccably sharpened. This will guarantee a high-precision cut and prevent delamination.

If you still haven’t managed to choose a cutting tool, then this is not a problem at all. You can safely go to the store and purchase fillets already prepared for joining. There is a different operating principle here. For frontal attachment of parts, it is recommended to make straight cuts rather than oblique ones. But their cost will be higher when compared with traditional accessories.

If you are going to cut the corners of the plinth in the room, then you need to start the work by purchasing a miter box. This makes it possible to select the required angle for working with a mounting knife or spatula, the dimensions of which will depend on the scope of the work being performed. To install a plastic structure, working with a miter box with low inclinations of up to 90° is quite suitable. Most likely, the most difficult stage is joining all the involved elements in such a way as to prevent the appearance of cracks. This time you will have to develop a sketch. The plinth is placed directly on the wall itself. If your tool kit does not contain a miter box, this moment, then the use of a stencil is quite applicable.

How to make a corner on a ceiling plinth?

To make a ceiling angle on a ceiling plinth, you will need two important components: glue and a ruler for measuring angles. At flat wall measurements are taken without any difficulty. But, if there are gaps, you will need additional measures. It is advisable to treat the corners with sealant in advance. In some cases it is desirable. Remember that the first thing you should do is decide what the corner of the product will be, and then do the rest of the manipulations, for example, cutting out the corner.

How to cut ceiling plinths in corners?

To cope with the task you need to know about certain nuances and prepare the appropriate tool. First of all, a mark is made on the length of the ceiling at which the baseboards are planned to be laid. The length at which the corner will be mounted and the cut will be made is measured using a miter box. Then sketches are prepared with length measurements. Cutting is done with a mounting knife. Miter boxes are now sold in almost all relevant stores.

How to cut ceiling plinth?

If you are planning repairs not at a professional level, then the most familiar tool will do. The radius of the corners should vary from 45 to 90 degrees. To eliminate common errors when cutting plinths, it will be important to develop a layout. This is quite acceptable when working with a plastic product. Its cutting is carried out using the edge of the miter box. If uneven edges are noticed, then cut with a mounting knife. In plastic skirting boards, it is better to be on the safe side by measuring several parts of the stucco molding, and only after that do their separation.

What are corners for ceiling plinths?

The corners of the ceiling plinth are also called baguettes. These products are pieces of plastic. They are characterized by a decorative component. Sometimes in everyday life it is possible to see such a name as ceiling cornices. Previously, their use was limited only to the decoration of public premises. Nowadays, cornices are used everywhere, including when decorating apartments. Also, measurements of the length of the ceiling are initially taken. Often, the production of ceilings comes down to the use of polystyrene, since its structure is quite compacted. Installing baguettes requires special concentration. Installation is probably no different from finishing the ceiling. Now the market building materials rich in skirting boards of various styles and textures. The aesthetic component of the corner is decorative, and the practical component is the protection of the outer corner.

What is a wooden ceiling plinth?

The wooden ceiling plinth is a modification of the decorative ceiling decoration. With its help, you can veil various unevenness and roughness of the wall, as well as add freshness and attractiveness to your interior. Besides plastic products There are also wooden ones. As a rule, they are sold in construction stores and on the territory of logging plants. It is better to choose the baseboard that will match general style your his . To hold the wooden ceiling cornice you will need screws and nails. Installation will take some time, although the installation itself is not that difficult. Sawing corners and filing pieces requires great care. Areas of future joints should be treated. You will need cutting tools wooden products. The docking technology is almost no different from other types of such products. The main thing is not to forget to correctly prepare the calculations of the joints. Then the docking will go flawlessly.

How to join skirting boards?

For this process You will definitely need a well-sharpened pencil and a utility knife. First of all, measure the perimeter and length of the ceiling of the room, making appropriate notes in pencil. If the surface is smooth, a simple miter box will be quite suitable. It is suitable for installing skirting boards at small angles of 90-120 degrees. To create grooves for further arrangement, cuts are made. Then the bar is placed under the miter box. If the edges are uneven, it is advisable to use a utility knife.

What is a foam baseboard?

In the building materials market, polystyrene has long ago gained high purchasing power. Its installation is simple. It has become widely used for ceilings foam baseboard. All this has now become accessible and varied. You can find such a product in any store that sells repair supplies. These products are excellent decorative qualities. As a rule, plinths are sold in separate pieces. It is fastened using a stationery knife and a miter box. Having determined the length, it’s a good idea to make notes with a pencil.

How to cut a corner for a ceiling plinth?

How to cut a corner? During installation, first of all, knowledge of how to cut the corner of the plinth plays a vital role. To measure the angle, you need to take a protractor and a marking pencil. This will help to calculate which side of the corner the piece should be placed on. If there are any unevennesses, this is done with a miter box at a low angle. Next, cutting out the required corners is done using a stationery knife. If you are using a plastic plinth, then an approximate diagram will be useful to avoid mistakes when connecting existing elements.




To have an idea of ​​how to accurately cut a plinth during installation, you will need to use a stationery knife to uneven corners, as well as a miter box used for smooth surfaces. For plastic components, a hacksaw for metal will be most suitable. It will provide easy trimming, which must be carried out with extreme caution, pressing lightly on the saw or knife, so as not to accidentally injure your hand instead of cutting a corner. The miter box is only suitable for flat surfaces. Often the product is cut at a slight angle, presumably at an interval of up to 90 degrees. An ordinary stationery knife also copes with this mission perfectly. When making cuts, you should avoid areas with cracks.

What is a miter box for ceiling plinth?

This is perhaps an essential attribute for processing ceiling plinths. It is equipped with two sides of cutting ends. Cuts miter box at all possible angles from 45 to 90 degrees. The baseboard ends up pinched on both sides. The cutting is carried out cutting tool. To correctly arrange the parts of the plinth you will need a pencil. They draw corners for joining. After everything is marked, the product is placed in a miter box so that it is on the surface. The plinth is held with one hand, and the material is cut with the other.

How to glue ceiling plinth?

In order to easily cope with this task, take into account the following basic rules:

  1. You need to start working from the corners of the room, since they are the simplest;
  2. Next, other parts of the room are involved in the preparation process;
  3. The corners are glued in such a way that there are no gaps;
  4. If the baseboard is made of plastic, then finishing putty is used for stucco moldings.

Apply primer generously to areas for fastening or plain water. After drying putty mixture It is recommended to seal all existing cracks. Sealants of various compositions are usually used to seal them. Professionals advise using substances that contain acrylic. As a rule, for one an ordinary room No more than one package will be required. In general, installation with sealant is similar to installation with putty.

- This is the design of the corner. You need to join the planks in such places very carefully, otherwise the appearance of the decor will be hopelessly ruined. Of course, you can use quite aesthetic special corner elements.

However, naturally joined planks usually look more harmonious. And in this case you won’t have to spend money on additional parts. Therefore, later in the article we will look at how to cut the corner of the ceiling plinth correctly and how to process the seam.

Cutting ceiling plinth

Ceiling plinths are made from the most different materials– polystyrene foam, polyurethane foam, plastic, wood. To trim them, tools available in every home can be used. Expanded polystyrene strips are cut with scissors or a knife. The wooden plinth is cut with a hacksaw. How to cut a plastic skirting board is also not a question. You can cut it with a regular hacksaw.

Trimming wooden plinths is done with a regular hacksaw.

What is a miter box?

For accurate and most precise cutting of ceiling plinths, a special tool is usually used - a miter box. It is a tray made of three boards. There are slots in its walls located at a certain angle to the axis (45, 60 and 90 degrees, etc.). They are designed to guide the hacksaw blade when cutting. You can purchase a miter box for the ceiling plinth at a hardware store.

Trimming the planks at an angle of 45 degrees is done in a miter box

Trimming ceiling plinth in a miter box

Trimming in a miter box is performed as follows:

  1. The right strip is placed in the tray from left to right with the wrong side on the bottom (the part that will subsequently adjoin the ceiling). The part of the connection to the wall should be leaning against the side board of the tray (closest to you);
  2. The bar is pressed tightly against the tool and cut through the slot.

How to make a corner of a ceiling plinth

Important: When trimming, you should remember that when decorating an internal corner, the edge of the plinth adjacent to the wall should be longer than that adjacent to the ceiling. When finishing the exterior, it’s the other way around.
  1. A second ceiling strip is inserted into the tray from right to left and cut;
  2. The finished planks are placed at the corner and the joint is adjusted using a knife;

The planks are placed on the corner and adjustments are made

  1. How to join the corners of a ceiling plinth? You can do this from a stepladder directly on the wall. But this is not very convenient, so experts advise combining polyurethane and foam elements and gluing them together on the floor special glue for joints.

It is best to glue the corner before installing the plinth on the walls

How to cut baseboard:

What to do if there is no miter box?

Thus, we figured out how to cut down a ceiling plinth (the video above may help someone figure this out better) using a miter box. But what to do if this tool is not at hand? In fact, it is possible to adjust the slats evenly without using it. There are two main ways to solve this problem: marking directly on the wall and making an imitation miter box.

In the first case, the procedure is as follows:

  1. The left strip is pressed tightly against the ceiling;
  2. With a pencil, line 1 is drawn directly on the ceiling along its upper edge;

How to properly cut a ceiling plinth without a miter box. Drawing the first line

  1. Next, the right ceiling element is placed on the ceiling and line 2 is drawn;
  2. A mark is placed at the intersection of the edge of the right bar with line 1;

A second line is drawn and a mark is placed on the plinth

  1. Next, the left element is again attached to the ceiling;
  2. A mark is also placed at the intersection of its upper edge with line 2;
  3. Now on each strip you need to connect the marks with the end of the lower edge of the plinth;

Then, along the resulting line, the actual cutting of the plinth is carried out at an angle.

Without using a tray, the planks can be mounted in the corner quite neatly

In order to cut out flat angle You can also use an imitation of a miter box:

  1. On smooth plywood sheet draw two strictly parallel lines;
  2. We put a point on one of them and, using a protractor, connect it to the second line at an angle of exactly 45 degrees (draw to the left);
  3. At a distance of 10 centimeters to the left of the first point we place the second;
  4. We connect it with the second line at an angle of 45 degrees (draw to the right).

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

The improvised miter box is ready. Now all that remains is to attach the right ceiling element (wrong side) on the right with the lower edge to the line closest to you and cut it off. The same with the left bar (only you need to apply it to the left).

Advice: You can cut polystyrene foam strips with a knife. However, sharpen it properly. Otherwise, the material at the ends will simply crumble.

How to connect planks if the corner is uneven

In city apartments, and especially in old ones, the walls are rarely even. Therefore, the angles between them are often not right. How to properly cut down the ceiling plinth in this case?

In fact, it is not as difficult as it might seem at first glance. You just need to measure the angle. For this you can use special tool malka or just make a template out of paper and use a protractor.

An uneven angle can be measured using a small protractor

We divide the resulting angle by two, draw the corresponding miter box on the plywood and cut off the strips. Next, you just need to connect them with glue.

How to clean up corners

We found out how to cut the corner of the ceiling plinth. Now let's see how to do finishing joints. How to cover the joint in the corner? If there remains a small gap here, the seal can be done with ordinary putty to match the color of the baseboard. The joints can also be sealed with silicone sealant.

The gap between the slats in the inner corner can be filled with putty

Important: Only the inner corner can be sealed with putty or sealant. The outer one should be adjusted as carefully as possible. It will be simply impossible to remove even a small gap in the future unnoticed. Especially when the baseboard is wide.

Corner elements for ceiling plinths

Trimming ceiling slats when in use corner elements(special connectors) is also usually performed in a miter box. How to file the planks in this case? Everything is very simple - the cutting is done at a right angle. If you don't have a tray, you can use a regular protractor or square. Corner elements (photo):

When using corner elements, strips are cut at right angles

How to properly trim floor plinths

Floor skirting boards can be made of PVC, polyurethane, wood or MDF. Just as in the case of ceiling plinths, they need to be cut, depending on the material, with a regular hacksaw (wooden) or a metal hacksaw (plastic).

You now know how to cut down a ceiling plinth. Next, let's see how to fit and trim the floor. How to use a miter box in this case? When trimming floor plinth The procedure is approximately the same as when making a ceiling image. For inside corner:

  1. We take the first strip and place it in the tray from right to left so that it lies in it the same way as on the floor. We lean it against the far wall of the instrument as if against a wall;

The strip is inserted into the tray and pressed tightly

  1. We trim the unnecessary piece from the left end at an angle through hole 1 (figure below);
  2. We insert the second strip from left to right in exactly the same position and cut it from the right end through hole 2.

How to cut a plinth in a corner if it is external:

  1. We insert the first strip into the tray in the same way as for the inner corner (from right to left);
  2. We cut it from the left end through hole 2;
  3. We insert the second strip from left to right and cut its right end through slot 1.

How to cut ceiling plinth for external and internal corners

Advice: The end at an angle of 45 degrees should be done not only to cut elements in the corners, but also to make joints on the wall itself. In this case, the connections will not be so noticeable.

Thus, you and I are the most in detail We looked at how to cut baseboards in corners. The procedure is not as complicated as it might seem at first glance. Once you start pruning in a miter box or using its imitation, you will see this for yourself.

How to cut corners of skirting boards: solutions for different materials

In this article I will talk about how floor and ceiling plinths are adjusted in the corners. As you know, it is made from different materials, and the reader and I will have to analyze the features of each of them.

Plastic

Floor

Here, cutting as such is not required: in external and internal corners the planks are joined at the corners; When connecting longitudinally, connectors are used.

From here there are two obvious conclusions:

  • The plinth is cut at right angles to the longitudinal axis;
  • Cutting accuracy may not be perfect. Please allow 1-2mm error.

The bar may be slightly shorter than the required size.
If you cut it off too much, one of the planks joining at the corner will simply not fit against the wall.

I cut the strips like this:

  1. I place the corner on the nearest corner and insert the bar into it until it stops;
  2. I mark the position of the next corner or connector;
  3. I retreat from the 3 mm mark, at which the plinth will fit into the connector or corner;
  4. Having laid the plinth on flat surface and attaching it to it construction square, I draw a line perpendicular to its longitudinal axis. Slight deviations are inevitable due to complex shape sections will not make any difference: as we remember, they are permissible;
  5. I cut the strip with a grinder with a cutting wheel for stone or steel. The cut is very precise and without burrs, unlike any saw; a knife (even the sharpest one) often breaks fragile plastic due to strong pressure.

If trimmed, I do it in this order:

Why is the lid cut separately? Because its displacement during cutting often leads to the fact that the length of the cover is 1 - 2 mm less than the length of the plinth. You know, we don’t need an untidy gap between the cover and the connector.

Ceiling

Ceiling plastic skirting boards And starting profiles used primarily in assembly suspended ceiling made of plastic wall panels. This ceiling is very practical in the bathroom or kitchen: it collects a minimum of dirt, is easy to clean and is absolutely indifferent to fluctuations in humidity.

Angular and connecting fittings However, it is not provided for skirting boards and edging profiles. How to cut the corners of the ceiling plinth in this case?

Cutting in a miter box

A miter box is a simple carpentry tool, which is a tray made of plastic or plywood with slots at angles of 90 and 45 (less often - 30 and 60) degrees to the longitudinal axis. The retail price of a plywood miter box is no more than 200 rubles.

How to cut corners on baseboards using this tool?

  1. Place the plinth or profile in the miter box tray, pressing it tightly against one of the side walls;
  2. We take a hacksaw and cut the plastic along the slot at an angle of 45 degrees, pressing the blade to one side of the slot. It is a hacksaw for metal that is needed here because its small teeth do not break plastic (unlike a hacksaw for wood) and leave burrs minimum size, which can be easily cleaned with a sharp knife.

Don’t forget that on the outer corners the edge of the plank does not fall on the corner, but protrudes beyond it by the width of the adjacent plank.

The instructions are extremely simple and... often giving disgusting results. The fact is that the slots in the miter box are just wide enough for a carpenter's hacksaw; a thin sheet of metal dangles in it, like... I think the dear reader will choose the appropriate association himself.

As a result, no matter how hard you try to cut exactly at an angle of 45 degrees, the blade will move to the side, at least a little.

Cutting with markings in place

How to cut corners on a ceiling plinth with greater precision and/or without a miter box?

Spatial imagination will help us. If we mentally combine both skirting boards in the corner, it turns out that the lines of the proposed cuts should pass through the intersection points of their edges.

  1. We apply the plinth or profile to the place of permanent deployment and draw pencil lines along its edges on the wall and ceiling;
  2. We repeat the operation with the second plinth;
  3. We reapply both planks one by one and mark on them the points where the edges intersect with the lines marked along the edges of the adjacent plank;

  1. Using a ruler, connect the dots on each plinth;
  2. Having laid each plank on level base, cut it off with a grinder with an abrasive wheel, keeping the plane of rotation of the disk strictly vertical.

Using this method, even cutting corners of ceiling plinths at angles other than 90 degrees will be accurate.

Foam, polystyrene foam, polyurethane

How to cut corners on ceiling skirting boards made of foam plastic and other foamed polymers?

Both of the above methods for miter cutting in corners are suitable for this material.

There are, however, a number of subtleties.

  • Polystyrene and materials based on it should never be cut with a hacksaw, abrasive disc or other tools that cause intense heating of the cut area. The low-melting polymer melts and hangs in untidy burrs or drops. For cutting, only a sharply sharpened knife with the thinnest blade is used;

The tool is a thin and sharp knife.

While cutting the baseboard in the last room I finished with an area of ​​about 19 m2, I sharpened the knife three times.
The first sign that your tool is too dull is that when cutting, the foam begins to crumble, and part of the cut exposes its granular structure.

  • When using a sufficiently long knife, cutting in a miter box gives a very decent result. The secret is simple: it is much easier to press the knife tightly against one of the sides of the miter box slot.

Wood

Cutting a wooden ceiling fillet or floor plinth is done:

  1. In a miter box using a regular garden saw. The width of its teeth at correct wiring matches the slots in the miter box quite accurately, and possible deviations of the cutting line are minimized. To avoid chipping the edges, avoid pressing hard;

  1. A very precise cut is obtained if it is marked in place using a grinder with a diamond wheel. Unlike abrasive discs, diamond discs do not char the edges. The main thing is not to rush, drive the disc along the marked line with minimal speed, pressure and in a strictly vertical position.

Useful little things

  • It is easy to seal the seams between polystyrene foam or polyurethane ceiling plinths using acrylic concrete putty. I've been using it lately for gluing baseboards and filling cavities between the uneven areas of the latter. For gluing, putty is applied to both planes of the plank, pressing against the ceiling and wall. Tool - spatula;

  • In the corners of wooden baseboards, cracks are sealed with acrylic wood putty, matched to the color. You can also prepare putty with your own hands: just mix PVA glue with sawdust left over from cutting;

Sawdust for putty is collected in a separate container when sawing wood and in no case is swept off the floor.
There will inevitably be dust in the estimate, which will affect the color of the improvised putty.

  • Floor skirting boards with cable ducts are convenient even if you do not plan to hide wiring or twisted pair local network. They allow you to securely fasten the plank with ordinary dowel screws and hide the fasteners.

Conclusion

I hope that my experience will be useful to the reader. See more clearly how skirting boards are cut in different cases, the video in this article will help. Please feel free to leave your additions and tips in the comments. Good luck, comrades!
