Before gluing the skirting boards to the ceiling in the corners, you need to prepare the tools that will be needed when gluing the ceiling skirting board:
- To calculate the required amount of materials, you need a tape measure.
- It is recommended to fix the ceiling skirting boards with quick-drying glue or putty.
- You can knead the adhesive in a pre-prepared container, it is best to apply the putty with a spatula.
- Remove excess glue or putty with a dry, clean cloth.
- For cutting skirting boards at a certain angle, it is best to use a miter box.
- Direct cutting of products is performed with a sharp construction knife or file.
It is recommended to glue the ceiling plinth on a previously filled and leveled wall. As for the wallpaper, they are glued after the fillets are installed. In this case, the fastening of the elements will be more durable. In addition, when gluing new wallpaper, there is no need to change the ceiling plinth, since wallpaper strips are glued along the lower edge of the fillet. Fixing over the wallpaper reduces the fixing strength of the skirting board and requires its dismantling when changing the finishing material for the walls.
The problem of how to properly glue the ceiling plinth in the corners is recommended to be solved using acrylic or silicone glue, characterized by fast drying, or on a construction putty. With the help of a putty, the skirting board is glued directly to the wall, the frieze is glued to the wallpaper using quick-drying glue. When using these materials for fixing products, there is no need to hold the elements for a long time to set the adhesive backing. In addition, with putty, you can simultaneously repair wall defects in the form of irregularities and cracks.
Using a thread or construction cord, it is necessary to draw a control line in accordance with the width of the frieze. In this case, you can count on a more even gluing of the ceiling plinth, and the process itself will not cause much trouble.
Cutting skirting boards at an angle
The process of deciding how to glue a wide ceiling plinth always starts in one of the corners. Many manufacturers in the process of manufacturing products cut the skirting boards at a certain slope for easier decoration of external and internal corners. The problem of fitting fillets with a complex pattern or pattern is especially urgent. When using a cornerless ceiling plinth, you can correctly and beautifully arrange the corner using a miter box or a file.
In order not to spoil the appearance of the baguette, it is necessary to properly cut off its corners. To form a normal right angle, the plinth should be cut at an angle of 45 degrees towards each other.
Determination of the slope and cutting of the skirting board is carried out as follows:
- The product is applied to the ceiling in order to understand the direction of the cut for proper installation.
- You need to cut baguettes in a mirror image.
- To decorate the inner corner, the top edge is made shorter than the bottom edge.
- Correct outer corner occurs when the top edge is longer than the bottom.
- On the ceiling plinth, which will be located on the right side, make a cut on the left side.
- The product located on the left side should have a cut on the right side.
- When cutting the skirting board, you must carefully advance the knife in one direction. In this case, the formation of chips and roughness can be avoided.
The appearance of the ceiling depends on the correct solution to the question of how to glue and cut ceiling plinths.
For self-production of a miter box, you must perform the following steps:
- Take any solid foundation and draw a line on it.
- Then they retreat about 10 cm and draw a line parallel to it.
- Draw a line through the parallels at right angles to them.
- From this line, 5 cm are measured on each line and opposite points are connected.
- The resulting lines form an angle of 45 degrees with the parallels.
To cut the skirting board using a homemade miter box, the product is laid along the parallels and cut along the marks, taking into account the direction of the corner.
However, it should be understood that for angles other than 90 degrees, it is necessary to cut the skirting board at a different slope. In this case, the product is applied to the wall and its boundaries are outlined. Then the place of intersection of the skirting boards is determined and the corresponding marks are put. The baguette cut is performed according to these marks.
How to glue skirting boards to the ceiling in the corners. step by step guide
When performing repair and finishing work, each stage should be treated responsibly. The final stage, when additional and decorative elements are mounted, requires special care. Most often they are in plain sight, so any mistake can spoil the appearance of the entire interior. Therefore, it is necessary to strive for the perfect execution of the final stages of repair and decoration.
The completion of any work on finishing the ceiling is the installation of ceiling skirting boards, which are called friezes or fillets. Thanks to this element, the transition between the ceiling and the wall becomes smooth, and the renovation takes on a complete look.
The main purpose of the ceiling plinth is to decorate the room, so you need to choose a fillet in accordance with the overall interior. In addition, this element allows you to mask minor defects at the junction of the ceiling and walls. Therefore, it is important to know how to glue fillets correctly.
Installation of a ceiling plinth cannot be called a complicated and time-consuming process; even a novice master can do it. However, for a high-quality work, you need to know all the intricacies of installing ceiling plinths. When solving this issue, you should be especially careful about the design of the corners. Errors and shortcomings at this stage cause the formation of cracks and mismatches, which to a greater extent spoil the appearance of the entire ceiling. Therefore, the problem of how to stick the ceiling plinth in the corners can be called actual.
Selection of material and calculation of the number of skirting boards
Ceiling plinths are very popular, for the manufacture of which polystyrene, polyurethane and expanded polystyrene were used. The main advantages of such products are lightness, resistance to moisture and temperature extremes. Thanks to the various widths and a large selection of patterns and reliefs, it becomes possible to choose a skirting board to create any decorative effect. Additional coloring of the ceiling plinths makes it possible to create a variety of artistic decor.
The problem of how to stick polystyrene and expanded polystyrene skirting boards on the ceiling should be solved with extreme caution, since they are easily deformed and damaged by mechanical stress. As for polyurethane fillets, such design elements are characterized by increased strength and the ability to maintain a clear relief shape.
Polyvinyl chloride ceiling plinth is widely used in cases where the budget for renovation and decoration of the premises is limited. However, when using it, it should be remembered that such products are not recommended to be painted. In addition, PVC skirting boards are afraid of temperature extremes, under their influence, product deformation may occur.
When choosing gypsum, wooden or aluminum skirting boards for ceiling decoration, you should remember a few very important points. First, such products cannot be bent due to the low ductility of the base material. Secondly, the skirting boards are quite heavy. The presence of these qualities makes the solution to the question of how to glue fillets on the ceiling, special.
Before you go shopping for skirting boards, you need to make a few calculations. In particular, it is required to determine how much material is required to finish the ceiling in a room of a certain area. First, you should measure the perimeter of the room, this value will correspond to the total length of the ceiling plinth. To calculate the number of fillets, it is necessary to divide the perimeter of the room by the standard length of the products, which corresponds to 1.2 meters, 1.4 meters and 2 meters. Experienced craftsmen performing finishing work recommend purchasing skirting boards of greater length, in this case, fewer connections are obtained.
The width of the skirting board is determined according to the height of the ceilings in the room. In rooms with low ceilings, it is better to use narrow products; for high rooms, it is recommended to install a wide ceiling plinth. This visually reduces the height of the room.
Gluing the ceiling plinth
For high-quality gluing of the baguette, you must do the following:
- Take a baguette and put glue on its back.
- The place of fixation of the product can be moistened with a primer or plain water to increase the adhesion of surfaces.
- The plinth is firmly pressed against the wall and ceiling and held for a while.
- Excess glue or putty is removed immediately.
- The resulting cracks and gaps are covered with putty.
If necessary, the skirting boards are painted in the desired color.
If you tried as best you could, but a small gap at the junction still “got out” do not be discouraged. In wooden fillets, such a gap is easily covered with furniture wax. To cover the gap on the baseboards made of polyurethane, foam, plastic or gypsum, a putty is perfect. Naturally, the color of the composition should match the color of the skirting board.
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 a wave, then it is better to buy narrow polyurethane fillets, they are elastic and will smooth out this drawback.
Perfectly flat walls are needed for a wide fillet.
Most of the questions arise about how to cut the wallpaper for 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, apply it to the corner and cut off the excess along the blade with a knife.
Cornice + Coving Ceiling Interior Exterior Angles + Miter Cuts
How to cut wallpaper for a ceiling plinth with your own hands.
But keep in mind. neither the knife nor the 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.
Method number 3. Applied universal
A 45º trim 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.
over, I can assure you that those angles that visually appear to be straight, in fact, have deviations by a couple of degrees. As a result, you buy a good tool, cut it off at 45º, and when joining, the gap between the skirting boards “comes out”. This problem disappears here. And then, using an example, consider how to cut a ceiling plinth in an inner corner.
Take the fillet, apply it on one side of the corner and draw 2 lines with it, along the wall and along the ceiling.
Advice: to make the lines inconspicuous, they can be drawn not with a pencil, but, for example, with a nail or the edge of a knife.
Method number 1. Classic miter box
The classic miter box is a U-shaped bed with slots in the opposite sides. A piece of a 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 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, the ceiling plinths are applied to the side of the miter box that is closer to you, and the floor plinths, on the contrary, must 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 skirting boards, as the miter box lies on a horizontal plane, it is easier for you to orient yourself in the position of the skirting board. People most often make mistakes when trimming the ceiling fillet, it is simply incorrectly put into the tool. There is a simple but important rule here.
Important: the side 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 on the ceiling is placed on the bottom of the miter box.
Skirting board trimming scheme.
The corner, as you know, has 2 sides, so, in order to make less mistakes, train yourself to put the bar that will be mounted on the right side of the corner into the miter box on the right, and the bar that is attached to the left, put it into the miter box on the left. Details about the intricacies of using the classic miter box are described in the video in this article.
How to properly trim the inner and outer corners of the ceiling fillet.
In addition to the classic U-shaped miter box, there are two more types of similar designs. a professional and a rotary tool. As for the professional version, only masters use it. The device is quite bulky, but it turns at any angle and has a hacksaw that can be fixed in the desired position.
Professional miter box with the ability to fix the hacksaw and part.
The swivel device can be safely called a “” miter box. The only advantage here is the ability to clearly fix the angle of rotation of the bar. On the one hand, it is easy to work with it. set the corner, put it on 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.
How to work with a swivel miter box.
Tip: when choosing a classic U-shaped miter box, firstly, do not take Chinese products. And secondly, try to buy models with the possibility of rigid fixation of the part inside, one of these models is shown in the photo below.
A miter box with the ability to fix a part inside is much more convenient to work.
How to cut a skirting board at any angle and without gaps. 3 working ways from a practitioner
There are more than enough tips on how to cut a plinth at 45 degrees on the net now, the only bad thing is that most of them are given by people who have never done this. Next, from the point of view of practice, I will tell you how to cut skirting boards at the corners with your own hands in 3 options, and you will learn both traditional methods and folk universal recipes.
The science of how to properly trim ceiling skirting boards in corners is not as difficult as it might seem.
Three working ways to trim skirting boards
For floor and ceiling skirting boards, the trimming instructions are almost the same. But if on the floor the 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 the ceiling plinths.
Method number 2. Cutting by 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 leaf. From the school geometry course, we know that the diagonal of any square in relation to the base has an angle of inclination of 45º.
How To Cut & Install Crown Moulding
The 45º angle can be set by attaching the plinth to the diagonal of the square.
Next, you need to draw a square and draw 2 diagonals in it. these will be the required 45º. You just have to correctly attach the plinth to the leaf and mark it. True, in order to cut off the plinth exactly without guides, you need a good eye and a right hand.
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 larger list:
The range of ceiling plinths is much wider than that of the floor direction.
- 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;
- Foam plinths are the simplest budget option, the price of foam plinths is low and they are cut very easily;
- PVC. the principle is the same as for floor skirting boards, but the range is much wider;
- Wooden. similar to the floor ones, only here there are still wide models;
- Gypsum. with the advent of polyurethane and polystyrene, gypsum ceiling fillets receded into the background, firstly, they are heavy, and secondly, fragile. But in fairness, it’s worth mentioning them.
Since it is impossible to properly 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 perfect tool for trimming all kinds of skirting boards and more is the swing miter saw. The high-speed disc makes smooth and precise cuts, and the bed in these units can be rotated at any angle. The only problem is the serious cost of this tool.
The miter saw is almost the perfect tool for trimming skirting boards and more.
It is believed that one of the best hand tools for accurately cutting small pieces of wood is the backsaw. In principle, this is true, but to be honest, a really high-quality saw, even with the current assortment, is not easy to find. If you still decide to buy a similar tool, then take a saw with a fine tooth.
The bow saw is convenient when working with a miter box.
In theory, foam and polyurethane can be cut with any sharp and sturdy knife. But at the same time, you need to have a firm hand and at least a little experience in cutting foam. Plus, it is very problematic to cut wide fillets with a knife.
Without experience, making a clear cut with a knife is very problematic.
Personally, in the absence of trimming, I only use a hacksaw for metal. It is suitable for cutting absolutely any material, from foam to wood. By the way, they often ask the question of how to cut a plastic baseboard for the floor, and so. take a hacksaw for metal and you definitely won’t be mistaken.
For trimming skirting boards, a hacksaw for metal is considered one of the best tools.
All three methods described by me work, the choice depends on which tool you have in stock and what your professional skills are. If after watching the video you still have questions, welcome to the comments, than I can, I will help.
If you are not confident in your abilities, then for both floor and ceiling skirting boards there are connecting elements that allow you to do without trimming.
Floor plinth: freehand inner and outer corner
Floor moldings are usually quite wide and thick, and therefore, finding only two points here, as for ceiling moldings, is not enough. To trim the inner corner, first set a point at its top at a height equal to the width of the plinth. in the figure, this is a green point. From it, to the left and to the right, we set aside a distance equal to the thickness of the plinth. points 1 and 2.
We apply the left segment to the wall, and from point 1 we draw a line along it, perpendicular to the wall and put a point on the edge. We repeat the action with the right segment, only drawing from point 2. In the figure, the point is marked with the number three. From it, across the plinth, draw a line to its opposite edge. we get point 4. Now we connect the green point with points 3 and 4. we get a line and an angle along which it will be possible to cut the molding.
How to cut a skirting board: make the necessary notes in the corners
Important: trimming the outer corners is easier than the inner ones. Set points on the left and right segments: A. the mark of the vertex of the wall corner; C. the point of intersection of the lines, which is obtained by alternately tracing the left and right sections of the plinth along the floor; B. from point C across the molding, a line is drawn to its opposite edge.
By connecting these points with each other with one line, we get a line along which the cut will be made.
Interior ceiling corner view
By analogy with the outer corner, we cut off the inner one. We only cut the inner left and right edges respectively.
It is important to remember: the product is always mounted upside down on the ceiling. Therefore, insert it upside down into the miter box. This will help you cut the skirting board correctly.
How to cut the corners of a skirting board without a miter box
If you are wondering how to properly saw down a ceiling plinth without a miter box, then the following information will be useful to you. We take the right segment of the ceiling plinth made of polystyrene, apply it to the installation site and draw a line on the ceiling along its upper edge. It should go beyond the points of the vertices of the corners by about 5 cm. Do the same with the left segment and put points at the intersection of the lines. We put the ceiling plinths in place one by one and transfer the resulting marks to them.
We figured out the upper part of the ceiling moldings, now we move on to the bottom. Everything is simple here, the marks we need are the tops of the corners. Mark their location with dots on the lower edges of the left and right ceiling plinths. Next, you need to connect the points on the moldings. this will be the trim line. This method will help to cope with even the most crooked corners. Adjustment, most likely, will not be needed, and if it does, it will be minimal.
How to cut a ceiling plinth without a special tool: the photo shows the marks for the intersecting point method
Important: the jobs described here require marking on the surfaces. Therefore, first you need to start cutting and adjusting the ceiling plinth, and only then think about how to glue the wallpaper. Or, if you want to fix the skirting board and over the wallpaper, markup and trimming are done before finishing, and gluing after it.
The first way is with a miter box
Professional miter box with rotary hacksaw
The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool is the oldest and simplest carpenter’s tool for cutting wood pieces at 90 ° and 45 ° angles. There are types of such a device for professional work, with a rotary mechanism, in which the cutting tool can be rotated and fixed in any position.
How to cut a ceiling plinth correctly
Ceiling corners 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 need three trims from 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 marking, slots are cut out for a hacksaw almost to the very bottom, and the boards are twisted.
Choosing a corner shaping tool
The most economical option is to buy a simple plastic miter box. It is a plastic block with eight working slots. Such a device is designed for only two operations: trimming at 45, 90 and 22.5 degrees. An angle of 90 degrees is useful, for example, if you need to embed a socket in the middle of the molding.
Some attachments come with eccentric clamps included. They are preferable, since it is easier to work with it. the plinth is clamped in the desired position and does not move during the cutting process. Accordingly, if flaws happen, then they are minimal and it will not be difficult to adjust the angle.
How to cut a plastic skirting board: a simple plastic miter box
If you have to renovate your own home, then it may make sense to purchase a more serious tool. a rotary single-plane miter box. It is designed for cutting at 15, 22.5, 30, 36, 45 and 90 degrees. The design of such a miter box includes 2 clamps. for clamping in the horizontal and vertical planes, as well as a stop that will allow you to cut the workpieces by one length. The hacksaw will be built in here. If it is not clear how to cut the ceiling plinth. the video review below will help you.
How to trim a skirting board in a corner: a swivel miter box
How to properly cut a ceiling plinth at a 45 ° angle
Corner pieces for skirting boards are easy to cut on the miter box and by hand. In the first case, you will need a miter box and a hacksaw, and in the second, a pencil and a hacksaw / knife on cardboard. The blade of the hacksaw should be well sharpened so that you do not have to think about how to cover up chips and roughness on the cut.
Method two. no additional tools
For the inner corner, you can use the simplest way of perfect joining. by marking on the ceiling. Another example of how to cut a corner nice and even.
- Apply a fillet to the ceiling, firmly pressing its even edge into a corner.
- Draw a line along the long side of the plinth on the ceiling.
The same action is done with the adjacent part on the other side.
Mark the point of intersection of lines.
The end result is an even 45 ° angle when you draw a line from the intersection to the edge of the part. Note that the above marking method works only at perfectly flat corners.
Some helpful tips to make your work and preparation easier
Next, we will talk about the tool with which you can trim. This section also contains useful information on joining skirting boards at corners.
How to cut a ceiling plinth in the corners. options and methods
Ceiling skirting boards are an integral part of the finishing of the ceiling space. With their help, cracks and wall defects are masked, they can be used to cover the irregularities of the suspended ceiling structure or wallpaper. In addition, skirting boards complete the interior of the room. One of the problems in the assembly process of these elements is the perfect joining in the corners. The question of how to cut a plinth to the ceiling in the corners is solved in several ways.
Cutting the skirting board in the corners without special tools
The question of how to properly cut off a 45-degree angle on a plinth can be solved without a special device. To do this, perform the following actions:
- Take a sheet of paper and apply a baseboard to it.
- Draw two parallel lines indicating the sides.
- Then they take a regular protractor and measure 45 0.
- A line of the future cut is drawn along the mark made.
- Before cutting the ceiling plinth, it is laid on a sheet of paper, while controlling the coincidence of the lines and sides.
- The markings from the sheet are transferred to the plinth and a cut is made in the right place.
The disadvantage of this method is the need to keep the saw on weight during the cutting process.
How to cut a skirting board for an angle other than 90 degrees
Many rooms boast angles that do not correspond to 90 degrees. Such situations arise as a result of shrinkage of the soil and the structure itself, as well as in violation of the technology of wall construction.
In this case, the correct marking with a miter box or drawing will not work, all actions are performed directly on the spot:
- Before you cut the corner of the ceiling plinth, it is applied to one of the walls and an emphasis is made with its end to the other wall.
- Draw a line along the plinth.
- Perform similar actions on another wall.
- At the intersection of the two lines, a mark is made on one of the skirting boards, which is connected to the corner of the workpiece. An incision is made along this line.
- Repeat the steps on the other plinth and try on both blanks. Make the necessary adjustments.
- The skirting boards are glued in place, the joint in this case must be tight enough.
How to cut a plinth for a ceiling
First, a miter box is used to properly cut the skirting board. This device is a special tray that allows you to cut wood, plastic or other materials at the desired angle. The miter box can be purchased in a retail network or made by hand; in the first case, a saw may be included in the kit. However, a tool available from a home craftsman for cutting materials may well be used.
The device has a recess into which skirting boards or boards are inserted. There is also a saw slot with an inclination of 45 and 90 degrees. For example, you can consider how to cut corners on a ceiling plinth at an angle of 45 0 using a miter box.
Such a process involves the following actions:
- The plinth must be attached to the attachment point.
- Make a mark for cutting.
- Install the plinth into the recess of the miter box, pressing it against the surface of the device with its underside. In this case, the side intended for applying the adhesive must look up.
- A saw is inserted into the hole for a 45 degree cut and the plinth is sawed off.
- Using the same saw or knife, the cut can be corrected by removing irregularities.
- The plinth is glued in place. The task of how to cut the ceiling plinth in the corners is considered solved.
Skirting board cutting tool set
Working tools when solving the problem of how to properly cut the ceiling plinth in the corners are selected depending on the material from which the plinth is made, since each of them has its own processing characteristics:
- The PVC skirting board has no resistance to mechanical stress at all. Even light pressure results in irreparable damage. Therefore, no great effort is required during the cutting process. The question of how to cut a PVC skirting board is solved using a blade, a sharpened construction knife or a hacksaw for metal.
- Polystyrene skirting boards are also not very durable, but in comparison with polyvinyl chloride they have a higher quality, moreover, they crumble easily. Cutting the foam ceiling plinth is done with sharp tools, just like PVC.
- Wooden skirting boards have higher strength characteristics and aesthetically pleasing appearance. However, the cost of such products is quite high. For cutting wood skirting boards, it is recommended to use a wood hacksaw with frequent teeth, since the teeth of a hacksaw for metal are easily clogged with sawdust.
Working with outside corners
As a rule, there may be external corners in the rooms, which also need to be pasted over with skirting boards. The question of how to cut the skirting boards at the corners of the ceiling in this case can be solved in the following ways:
- Using a miter box. Almost the same actions are performed as for internal corners. The only difference is that the glued side of the plinth is pressed against the surface of the device.
- The markup is in place. Similar to the inner corners on the ceiling, lines are drawn and the same technology is used. With a rounded external corner joint, the joint is finalized with a knife.
Self-made miter box
The miter box can be made by hand using wood or metal. The width of the workpiece can be different, the main thing is that it does not exceed the size of the hacksaw, in this case, such a task as cutting off the corner of the ceiling plinth will be easier to complete.
The manufacturing process is as follows:
- A transverse line is drawn in the center of the workpiece.
- From it, in both directions, measure half the width of the workpiece and make marks.
- Labels connect crosswise.
- Now you need to mark the side walls of the device.
- The walls are alternately applied to the base and marks are made in accordance with the markings on it.
- These marks are used to draw straight transverse lines along the walls.
- Next, they start assembling the miter box. The side walls are attached to the base with self-tapping screws or bolts, depending on the material used.
- Saw slots are made after hollow assembly of the fixture.
Using a factory-made or self-made miter box, you can speed up the process of cutting skirting boards up to 10 times. This is especially important for craftsmen who regularly carry out repair work and are faced with the task of how to cut a ceiling plinth.
