No matter what expensive repairs you undertake, you are unlikely to be able to avoid unevenness at the boundary between the wall and the ceiling. To hide them, use ceiling plinth.

Types of ceiling plinths

Today there is a huge range of ceiling plinths on the market. Here are the materials they are made from:

• polystyrene;
• polyurethane;
• gypsum;
• Styrofoam.

A wide variety allows everyone to choose the right one. Ceiling plinths are narrow and wide, the simplest and decorated with exquisite patterns and reliefs. So don’t neglect this construction find, because the ceiling plinth will give a completely finished look to your renovation and decorate any room.

Since installing ceiling plinths is not a difficult task, many people prefer not to spend extra money on skilled workers, but to install them themselves. How to properly cut and attach a ceiling plinth? Let's consider this issue further.

Since the average person does not have many specialized construction tools, we suggest you familiarize yourself with the recommendations on how to cut the corner of a ceiling plinth using simple tools. To do this you will need:

1. Miter box.
2. Saw for metal.
3. Sharp knife.

A miter box is a tray with special slots under different angles. Such a tool is a necessary thing in the household, and it is also inexpensive. To trim the corners of the plinth, you just need to take a miter box with angles of 90 and 45 degrees.

To cut the corner of the ceiling plinth, follow these steps:

As you can see, there is nothing complicated in this operation. But how to cut a corner of a ceiling plinth if you don’t have a miter box? There is an exit. You need to proceed as follows:

If in this case you cannot make an even cut, draw lines on a sheet or board with a 45-degree intersection and attach the baseboard to them so that the line drawn on it corresponds to the indicated angle. It is better if someone helps you in this case and fixes the ceiling plinth on such a homemade miter box so that you can trim the edges evenly.

It happens that uneven walls do not allow the plinth to be glued evenly, even after it has been perfectly trimmed. In this case, you need to determine the degree of pruning individually. That's why it's so convenient to use a homemade painted miter box.

To avoid damaging the ceiling plinth, practice doing this on small pieces before cutting it. This way you can get better at cutting and make cuts more confidently every time.

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 properly trim ceiling moldings in corners is not as complicated 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, almost ideal tool for trimming any skirting boards and more 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, they are applied to the side of the miter box that is closer to you, and floor skirting boards on the contrary, you need to apply it to the side of the instrument farthest from you. This is not a dogma, but it is much easier to work this way.

It is easier to work with floor skirting boards, since the miter box lies on horizontal plane It’s easier for you to navigate the position of the plinth. People most often make mistakes when cutting ceiling fillets; they simply insert them into the tool incorrectly. There is a simple but important rule here.

Important: the side of the ceiling fillet that 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 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 ensure that the bar that will be mounted with right side put the corner into the miter box on the right, and put the bar, which is attached to the left, into 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 of similar designs - professional and rotary tool. As for the professional option, 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 specialized tool is not nearby, then an improvised miter box can be drawn on a piece of notebook paper. From the school geometry course 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. 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, 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 is easily covered up 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.

Ceiling plinths are very often used for decorating rooms. They give the ceiling a complete look and allow you to convey a particular style in the interior. In addition, they serve to mask the joints between the walls and the ceiling, where the two join various materials. Although such elements are not always present in the premises, they make the interior more complete. In the following material we will describe in detail how to cut the corner of a ceiling plinth, since in such places the joining of individual elements often poses a problem for inexperienced builders.

If the room has simple form, then only the internal corners will need to be cut. But in the premises there are more complex configuration, with columns, partitions and niches, there will also be external corners. To decorative elements looked beautiful, pruning must be done correctly and carefully, otherwise appearance the ceiling will be damaged.

To cut the ceiling plinth in the corners as best as possible, you can use high-quality and sharp tools or other means. The type of tool that will be used to cut skirting boards depends on the type of material they are made of. Thus, ceiling plinths are made from PVC, polystyrene foam, polyurethane and wood.

The cheapest option is PVC skirting boards. They are soft, so it is easy to leave dents and creases on them that cannot be corrected in any way. In addition, this material has the property of attracting dust. A hacksaw or sharp knife is suitable for cutting such skirting boards.

Another fairly cheap type of material is polystyrene foam skirting boards. They crumble easily, so to cut the corners of the ceiling plinth you should only use a sharp knife or a hacksaw. Movements should be soft, without pressure.

Cutting plinths to decorate the ceiling

Another type of ceiling plinths is made from extruded polystyrene foam. They are much denser than ordinary foam plastic products (therefore they do not crumble), they cost a little more, but they are also somewhat more difficult to cut. For work, you can use the same knife or hacksaw for metal.

The most expensive skirting boards are made from polyurethane. These are elastic, strong and moisture-resistant products that are very easy to cut construction knife. True, they cannot be used in all rooms, since polyurethane is sensitive to high temperatures– it becomes deformed, begins to crack or crack.

To work with wooden skirting boards Only a hacksaw with fine teeth is suitable; you can use a metal tool.

However, many novice craftsmen are interested not so much in what, but in how to correctly cut the ceiling plinth in the corners. This process requires careful calculations and accuracy from the performer. In some cases, if the interior of the room allows, you don’t have to think about how to cut a corner on the ceiling plinth, but use ready-made corner elements. They can be purchased at construction stores. In this case, the plinth is simply cut straight and inserted into the corner element. All irregularities and flaws will be hidden.

Using a miter box to cut baseboards

Often used in carpentry special device made of wood, metal or plastic - miter box. There are special slots made in it that allow you to make an even cut at 90º, 45º, and in more complex devices – also at 60º. There are also professional miter boxes equipped rotating mechanism. In them cutting tool can be installed and fixed at any angle to the workpiece. Before you make a ceiling plinth in the corners, you need to understand the details.

To cut the inner corner of a ceiling plinth using a miter box, you must:

• First, you need to attach the baseboard blank to the ceiling surface and mark the length.
• Now the piece of plinth is placed in the miter box in the same position as it should be placed on the ceiling.
• The plinth is pressed tightly against back wall miter box.
• Hold the workpiece with one hand so that it does not move during cutting.
• The hacksaw is installed at an angle of 45º to the workpiece.
• Cut the plinth, controlling the degree of pressure of the hacksaw so as not to damage the product.
• Then they move on to cutting the counter piece of plinth. It is also applied to the far wall of the miter box.
• The workpiece is pressed and held by hand so that it does not move.
• The hacksaw is installed at an angle of 45º to the workpiece so that the cutting direction is opposite to the first element of the plinth.
• Cut off the corner of the plinth.

After trimming the ceiling plinths in the corners, they proceed to joining the resulting elements. If the cutting was done accurately, they will fit tightly together.

Let's look at how to cut external corner ceiling plinth using a miter box:

• It is best to start marking and measuring the ceiling plinth from the inner corner, and only after completing it, start cutting the outer corner. Otherwise, the plank may be short and not enough to fill the entire length of the ceiling.
• The plinth is applied to the ceiling and its length is marked.
• Then the workpiece is placed in a miter box and pressed against the front wall.
• The hacksaw is placed at an angle of 45º and, holding the workpiece with your hand, the corner is sawed off.
• Similarly, it is necessary to cut off the opposite part of the outer corner.
• The workpiece is pressed to the front of the miter box.
• The hacksaw is placed at an angle of 45º to the baseboard and the workpiece is sawed off.

Upon completion of the work, the pieces of plinth are joined together, checking that everything is done correctly and evenly.

Marking on the ceiling to make a corner on the plinth

Exist different ways How to correctly make a corner on a ceiling plinth. Some are easier to do, others are more difficult. One of these methods is to mark the baseboard on the ceiling. True, cutting skirting boards by weight is not very convenient, but in accuracy this method is not inferior to all others. Before cutting the plinth for the ceiling, it is applied to the surface, while all the imperfections and unevenness of the walls, as well as the size of the corners, are immediately taken into account.

Let's take a closer look at how to correctly make corners on ceiling plinths using this technique:

• First, the two mating plinth strips must be cut at an angle of 90º;
• One of the blanks is pressed against the wall, and its end is pressed against the opposite wall. Then the outline of the workpiece is drawn on the ceiling.
• On next stage take the second plank and press its end against the wall in the same way. Draw a line.
• At the intersection of the resulting lines, a point is placed at which further trimming of the skirting boards will be carried out.
• Then each of the planks is applied to the ceiling in turn and the cutting point is transferred to the workpiece.
• From this point, a diagonal cutting line is drawn into the corner of the plinth.

It is worth noting that this method is most often used for internal corners.

Applying a miter box template

To cut the plinth in the corner of the ceiling as evenly as possible, instead of a regular miter box, you can use paper, cardboard or wooden template. Two parallel lines are drawn on it, then the central point is found and any necessary angle is laid off from it using a protractor. Before cutting the corner of the ceiling plinth without a miter box, it is worth double-checking the size of the internal or external angles between the walls of the room, using the same protractor.

The principle of cutting corners using a template is similar to using a standard miter box. In this case, the workpiece must be pressed against a parallel line and, setting the hacksaw at the desired angle, saw off the workpiece.

How to make a miter box yourself

Often, the only way to evenly cut the corner of a ceiling plinth is to use special devices so that the tool does not move to the side during the cutting process. In this case, you can make a miter box yourself.

Option 1. A box in the shape of the letter P is made from three boards. The required corners are marked on the walls of the box and slots are cut in the appropriate places. The result is a complete device.

Option 2. Sometimes it is quite difficult to make the corners on the skirting boards on the ceiling as even as possible, especially if you have to hold the workpiece in weight. In this case, you can use homemade device. Take two boards and knock them down into a corner shape. Then lines are drawn on a sheet of paper or cardboard with the right angles, apply the template to the corner. Then press the plinth, place the template under the cutting area and saw off the corner along the lines.

Option 3. If you are still in doubt about how to properly cut the corner of the plinth, almost anyone can help with this household item, the shape of which allows you to form an angle. This could be a chair or a table, simply placed close to the wall.

To understand how to properly cut a ceiling plinth, you should also familiarize yourself with the rule for measuring workpieces. So, to make an internal corner, the length begins to be measured directly from the beginning of the corner. But to determine the external corner, it is worth considering that it will protrude into the space of the room by the width of the product.

There is no need to rush and fix the workpieces before the mating plinths in the corner have been completed. In order not to redo the work, you must first make sure that the joining surfaces fit tightly to each other and to the ceiling. Small defects can be corrected with a file, thin nail file or knife, depending on the material of the product.

If cutting the skirting boards in the corners did not work out perfectly, small cracks can simply be filled with putty. In general, the process of cutting skirting boards at the corners is not at all difficult. However, for practice, you can take several small pieces of baseboard and practice on them.

The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This instrument represents the most ancient and the simplest tool carpenter's cutter wooden parts at an angle of 90° and 45°. There are types of such devices for professional work, with a rotating mechanism, in them the cutting tool can be rotated and fixed in any position.

How to cut ceiling plinth correctly

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

If necessary, you can make a miter box with your own hands. To do this, you will need three scraps of plywood or boards of the same size. First, they are applied in the form of an inverted letter “P” and the corners are marked. Then, according to the markings, slots are cut for a hacksaw almost to the very bottom, and the boards are twisted.

Internal corner

• • We take the correct measurements.
  • We install the plinth strip in the miter box so that this position exactly coincides with the placement on the ceiling.
  • The plinth should be pressed tightly against the opposite wall of the miter box. We hold and press with our free hand.
  • Place the hacksaw at an angle of 45° in the special hole and cut off the part.

• The adjacent part must be cut in the same way, only in mirror image, as shown in the photo.

When circumcised soft materials(PVC, polystyrene foam) use a hacksaw or a regular construction knife. Then the work will be neat and with smooth edges.

External corner

• Measure the length of the plinth from the nearest wall to the outer corner, leave a line on the inside with a pencil, indicating desired length. It must be taken into account that the edge (its top part) should come out a little.
• The plinth is moved into a miter box and cut off.
• The adjacent strip also needs to be measured with a margin and cut in a mirror image to the first part.

Let's try on the ceiling plinth: the joining of the parts should be perfectly even. If the result is not achieved and there are unevenness at the joints, you can trim the edges with a regular knife until the joint is perfect.

Checking the alignment

The video describes all the nuances well:

Method two - without additional tools

For the inner corner, you can use the simplest method for perfect joining - by marking it on the ceiling. Another example of how to cut a corner nice and even.

1. 1. Apply the fillet to the ceiling, pressing its smooth edge tightly into the corner.
   2. Draw a line along long side plinths on the ceiling.

1. 1. The same action is performed with the adjacent part on the other side.

1. 1. Mark the point of intersection of the lines.

The result is an even angle of 45° if you draw a line from the intersection point to the edge of the part. Note that the above marking method only works with perfectly even angles.

other methods

With a good eye and precise hand action, you can use a homemade template that resembles an imitation of a miter box. To do this, take a thin board or thick plywood and draw a layout in the form of a horizontal rectangle. Use a protractor to mark 45° on the right and left sides of the rectangle. Draw lines connecting opposite edges.


Now you can cut the ceiling plinth using this layout. The steps are simple and similar to the description above in the first option. Only the ceiling parts should not be inserted, but placed on the drawing and the hacksaw should be combined with the layout markings.

Special components for docking

When installing ceiling plinths, you can bypass the question of how to cut the corner side. In a situation where you don’t want to cut anything, if you are a woman and love beauty and not carpentry, you can go the other way. We advise you to choose a plinth for your finishing, to which in the store you will find a part that matches the design and covers the joint. This method will save time and effort.

Today it is impossible to imagine the interior of a residential building or apartment without ceiling skirting boards. Skirting covers uneven areas suspended ceiling or wallpaper, cracks and imperfections in the walls, gives the interior completeness. But how to make sure that the plinth fits perfectly in the most important place - in the corner? There are several ways.

Using a miter box

A miter box will help you correctly cut the plinth for installation in a corner - a special device that is a tray for cutting boards, plastic, etc. at different angles. You can buy a miter box in a store or make it yourself. Usually a miter box sold in stores comes with a saw, but you can also use your own tool.

The miter box has a recess for the board or plinth to be cut and slots for the saw, located at an angle of 45 and 90 degrees. You will need to cut the baseboard at a 45 degree angle.

To cut a baseboard using this device, you need to follow these steps.

1. We apply the plinth to the future mounting location.
2. We mark where we will cut.
3. We place the plinth in the groove of the miter box so that the lower part is pressed against the surface of the device, and the part that will be lubricated with glue “looks” up.
4. We cut off the section by inserting the saw into one of the 45-degree holes.
5. We correct the cuts using a knife or the same saw (we remove irregularities).

After this, the plinth can be glued into place.

How to make a miter box yourself?

If desired, a miter box can be made at home. It can be made from wood or iron. The dimensions of the workpiece do not play a special role, but the wider it is, the more accurate your cuts will be. However, if the width is greater than the length of the hacksaw with which you will cut the baseboards or boards, then sawing will be extremely inconvenient, so you do not need to take a workpiece that is too wide.

First, a transverse straight line is marked in the center of the workpiece. Then, at a distance of 1/2 the width of the workpiece from the intersection of the straight line with the edges of the workpiece, marks are made. Then these marks are connected crosswise, as shown in the figure.

Next, the process of marking the side walls of the miter box begins. Attach them to the already marked base and make marks, focusing on the markings of the base. Then draw straight lines from these marks across the entire wall.

After this, the process of installing the miter box begins. The walls must be attached to the base using self-tapping screws if the device is made of wood or chipboard, or corners with bolts if it is made of steel. Only after installation, the slots for the saw are cut in the miter box.

After making the slits, the miter box is ready. If you have a large amount of work or want to do repairs regularly (on a professional basis), this simple device can speed up the process of cutting skirting boards by 5-10 times.

How to cut a baseboard without a miter box?

The easiest way is to draw the future cutting line on paper (cardboard, wallpaper), and then, attaching a plinth blank to it, cut it off.

To do this, you first need to attach the baseboard blank to the paper and draw two parallel lines that will mark the sides of the baseboard. Then, using a protractor, you will have to measure 45 degrees and draw a line for the future cut. Then the drawing is used in the same way as a miter box: a workpiece is placed on it and the excess is sawed off along the line.

The disadvantage of this method is that the saw will have to be held suspended, focusing on the drawing, and not inserted into a pre-prepared slot.

If the angle is not right

Unfortunately, in some cases the angle between the walls in a room is not straight, but acute, or, conversely, obtuse. This is due to design defects that arose due to the fault of unprofessional builders, the architect’s idea, or the result of soil subsidence some time after the construction of the building. This is especially common in village houses and dachas.

No miter box or drawing replacing it will help in this case, and you will have to make markings in place.

1. Place the workpiece against one of the walls so that its end rests against the other wall.
2. Draw a line on the ceiling along the workpiece.
3. Carry out the same operation against the other wall.
4. At the intersection of the two lines, place a mark on the workpiece itself.
5. Draw a line from the mark to the corner of the workpiece and cut along it.
6. Do the same with the workpiece that you will attach to the other wall.
7. Glue both blanks; they will fit tightly.

External corners

It happens that a room has not only internal, but also external corners, which also need to be covered with plinth (see photo). How to do it? There are several ways here too. The easiest way, as in the case of internal corners, is to trim them using a miter box. The external joints must be cut so that the side that will be glued to the ceiling is on the surface of the miter box, and the side pressed against the wall is facing the wall of the device.

As in the case of internal corners, you can also use markings “in place”, that is, draw lines on the ceiling. Here the technology exactly repeats that used for internal corners.

You can use markings on the wall by attaching a blank and drawing a line along its lower edge (see photo).

If the outer corner turns out to be too rounded, you can refine the joint using a knife.

To the point where they converge, a line is drawn directly along the future part of the connection. From the point on the ceiling to the second one. The resulting marking will be the line along which you need to saw off or cut off the connecting parts. Using these techniques, you no longer have to wonder how to cut the corners of the ceiling plinth.

What tools can you use?

The feasibility of using certain tools is related to the materials from which the plinth will be made.

Table 1. Types of materials and features of their use.

Type of material	Material properties, requirements	Tool
Polyvinyl chloride (PVC)	PVC skirting boards are distinguished by the fact that they are easily damaged when pressed and no longer restore their former appearance, since they lack elasticity. Therefore, such skirting boards cannot be pressed when cutting.	Cut with a construction knife or a hacksaw. A blade or sharpened kitchen knife will also work.
Styrofoam	Foam plinth is also not very durable, but it is better than its polyvinyl chloride counterparts. Easily crumbles.	You can use the same tools as for PVC
Tree	Stronger and more aesthetically pleasing than their polymer counterparts, but more expensive.	It is best to cut wood with a hacksaw; you can cut it with metal, although this way you risk clogging the teeth of the blade with sawdust. A wood saw with fine teeth is best.

Using factory corners is an alternative to cutting and sawing

Instead of cutting out skirting boards, you can use ready-made corners, which are sold in the same hardware stores. In this case, the main plinth can simply be measured and cut in the usual way, at a right angle, and then attach end-to-end with the corner element.

The disadvantage of corner elements is that they are actually and visually larger than the baseboard, which is why the corner will be noticeable. This can ruin the look of the room. It is also inconvenient to use corners where the walls do not meet strictly at an angle of ninety degrees. But in most cases they look great.

Conclusion

Thus, cutting corners when gluing skirting boards is one of the most complex and responsible procedures for which it is advisable to use special device, – miter box – which allows you to cut the baseboard at an angle of 45 degrees. If the angle between the walls is not straight, you have to use manual marking. The cutting tools used depend on the material from which the baseboard is made.
