Methods for cutting the ceiling plinth for joining in the inner and outer corners using a miter box, template or by marking the wall. Tool selection rules and useful tips.

The content of the article:

One of the most difficult steps in installing skirting boards is cutting them correctly. Only by correctly joining the individual elements at the outer and inner corners will you get the desired result. Fillets will look aesthetically pleasing and neat if you cut them off at the right angle and seal the cracks. To accomplish this task, a special tool (miter box) is used. And if it is not, then other devices will help.

Selection of tools for cutting ceiling skirting boards

To properly and accurately cut the skirting board, you need to use a suitable cutting tool. It is chosen depending on the material from which the fillets are made:

• Styrofoam... It is characterized by low strength and is relatively inexpensive, and therefore foam models are becoming more and more popular. Their strength does not particularly affect the performance, since usually the ceiling plinth is not subjected to mechanical stress. A regular stationery knife is suitable for cutting.
• Extruded polystyrene foam... A cheap material with a density several times higher than that of foam. Because of this, cutting it is a little more difficult, and therefore a sharp and thin knife is used for this purpose.
• Wood... Such skirting boards are more difficult to process, although they have many advantages (environmental friendliness, durability). They cost more
  especially if made of hardwood. Before cutting a wood skirting board, stock up on a hacksaw.

In addition to the tool for direct cutting of the baguette, you will need a miter box. This is a special device made of wood, plastic or metal in the form of a box with notches on the sides. A hacksaw or knife can be inserted into it at the desired angle. Thus, the cutting angle is as accurate as possible.

It can be purchased at a hardware store or made by hand according to the following instructions:

1. We knock three boards 50 * 15 cm with a long edge in the shape of a three-sided, rectangular box. Please note that an angle of 90 degrees must be observed between the side rails and the transverse plank.
2. Using a protractor, mark an angle of 45 degrees on the bars. Instead of a protractor, you can use a school square. In it, one angle is 90 degrees, and the other two are 45 degrees each.
3. Before cutting the corners, mark the vertical direction with a simple pencil.

To work with this homemade device it was convenient and safe, the boards need to be well sanded before bonding.

Cutting technology for ceiling plinths

For a prompt and high-quality work, you need to choose a tool in accordance with the material of the baseboard and choose a cutting method. If you have a miter box, then there will be no particular difficulties in the process. If it is not there, then two options are possible: cut according to a template and measurements on the ceiling, or make this tool yourself.

Features of cutting ceiling plinths in a miter box

It is necessary to work with this device extremely carefully so as not to blunt the tool and not leave cuts in unnecessary places. In the process, we adhere to the following instructions:

• We fix the baguette in the miter box in the same way as it is planned to place it on the wall. The side that will be pressed against the ceiling on the miter box must be in contact with the sidewall.
• We insert a cutting tool (hacksaw or knife) into the desired gap and cut the fillet.
• We process the joint of the ceiling plinth and apply it to the wall to check the correctness. The foam molding can be tweaked with a sharp knife if the roughness of the end is about 2 mm. Wooden skirting boards can be simply sanded with sandpaper. For ease of use, it can be glued to a wooden block.

When cutting and trimming foam and polyurethane products, remember that these materials crumble and squeeze, so the tools must be sharp enough, and strong mechanical stress is undesirable.

Technique for cutting ceiling plinths according to a template

This method can be used if your corners are even and you want to trim the baguette exactly 45 degrees. To do this, before cutting the ceiling plinth in the corners, you need to draw a miter box on thick paper. Draw two parallel lines and mark the angles at the desired degrees using a protractor.

We place the fillet in this case in the same way as on a traditional miter box. Please note that you need to cut the skirting board while holding the tool in a strictly vertical position.

Rules for cutting ceiling plinths by marking

This method is used for cutting skirting boards in cases where there is neither a miter box nor parts from which it can be made.

To do this, you need to make markings on the wall in this order:

1. We put the baguette in the corner to the place of fastening.
2. Along its one edge, draw a baseline on the ceiling for the level of attachment.
3. We apply the fillet in the same way to the perpendicularly drawn line on the ceiling and again draw a straight line along one side. We should have two segments that intersect at one point.
4. We again apply two skirting boards in turn and mark this point on them.
5. We repeat the same procedure now on the wall to mark the place of cutting from below on the products.
6. We connect two points with a line. It can run at an angle of 38-45 degrees, since walls and corners are living rooms often uneven.
7. Cut off the baguette along the drawn line.

When cutting in this manner, it is important to accurately trace all lines and mark points. An error of even a few millimeters will cause a gap to form. This method is suitable for cutting and joining both the inner and outer corners of the ceiling plinth.

Method for cutting a ceiling plinth without a miter box

To neatly dock fillets in the inner corners, you can do without a miter box.

We carry out the work in the following order:

• We apply the end part of the baguette to the sheet of paper and outline the contour of the convex side. It is more convenient to use a small piece of plinth (if any).
• Cut out the resulting template.
• We transfer the contour to the surface of the baguette with a simple pencil.
• Cut along the drawn curve.
• For fitting, one plinth is applied tightly with the end part to the wall, and then the second.
• If there are small gaps, then they can be processed with a clerical knife or subsequently sealed with a sealant.

When working with a miter box, there are two things to keep in mind:

1. The inner corner of the ceiling plinth is formed from two elements: the first one we put on the right in the miter box and cut from right to left, the second we start from the left and cut from left to right.
2. We start the first part of the outer corner from the left and cut from right to left, the second we start from the right and cut from left to right.

In addition, you need to know the following nuances before cutting the skirting board:

• Before you start cutting a baguette with a miter box, try cutting a test strip to avoid mistakes.
• You can make the correct measurements by measuring the length of the inner corners of the plank on the inner side, and the outer corners from the point of the inner corner to the width of the fillet deep into the room.
• If the baguette is installed under stretch ceiling, then attach it only to the wall. The adhesive should never get onto the vinyl.
• The final fixing of the skirting board should be carried out only after the exact fit of the plank.
• If the corners and walls in the room are even, then the fitting can be done on the floor.
• When installing baguettes, it may be necessary to adjust them several times, therefore, stock up on tools and patience.
• Instead of a template and a miter box, you can cut in the corner between the wall and the floor, or by moving the table against the wall. In this case, the end cutting angle should be marked on the wall, ceiling and baguette.
• If you are interested in the question of how to cut a ceiling plinth without a miter box, and you do not have time to use templates, then you can purchase special corner inserts in advance. They will hide the gaps, but will protrude and stand out on the surface.
• If you have a skirting board made of fine wood, then you need to cut and install it very carefully, because a large number of putties for sealing joints will be too noticeable, and painting over a baguette is an inappropriate decision, because this way you will hide the natural texture of the array.
• Styrofoam products do not have to fit close to each other due to the soft texture, but wooden and plastic models should be well matched.
• If the trapezoidal niches on the wall need to be bypassed from above with a plinth, then we join the piers at an angle other than a straight line.
  In this case, cut the plinth at an angle equal to half the joint. For example, if the walls are joined at an angle of 120 degrees, then we cut the fillet at an angle of 60 degrees.

How to cut an inner and outer corner on a ceiling plinth using a miter box

Have you decided to install a ceiling plinth (fillet, molding)? Want to hide the seams and get a finished look? While doing the work, you can face a lot of nuances. To avoid difficulties, you should figure out how to cut the ceiling plinth in the inner and outer corners, what is a miter box and how to make it. This is what we will do.

Tools

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

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

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

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

Cut corners

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

Internal slope

Internal corner cutting is performed step by step in a specific order:

1. First, measure the desired length of the plinth on the ceiling.

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

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

1. Press the workpiece against the far wall of the tool, holding it with your left hand.
2. The next step is to set the file at a 45-degree angle so that its handle is as close as possible to the left hand. Trim the skirting board without applying too much pressure to the saw.

1. Next, you need to cut off the striker. For this, the workpiece is installed against the far wall.
2. We hold it with our right hand.
3. Turn the hacksaw at an angle of 45 degrees. In this case, the handle must be turned to the right. Then the skirting board can be cut off.

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

By following this algorithm, you can get the job done with millimeter precision. And the question of how to cut the inner corner will already be closed.

External slope

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

To decide how to properly saw down the outer corner, you must act in a strictly defined way:

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

1. Holding the plank with your left hand, turn the handle to the left 45 degrees with a hacksaw and cut off the plinth.
2. To saw off the striker, place it closer to the front wall of the device, holding it with your right hand. Saw off the skirting board at a 45-degree slope by turning the handle to the right.

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

We make a miter box ourselves

Sample

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

• first, two clear lines are drawn in parallel;
• between these lines, a center point is determined and marked on paper;
• using a protractor, the required angles are drawn, which can be more than 90 degrees.

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

Miter box

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

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

Other ways to trim corners

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

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

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

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

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

Types of fillets

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

• polyurethane;
• polyvinyl chloride;
• polystyrene (foam);
• wood.

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

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

• PVC skirting boards are distinguished by a favorable price. However, the material is capable of storing static electricity.

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

• Wood skirting boards are natural materials, but their disadvantage is exposure to moisture, high temperatures as well as a relatively high weight.

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

Now you know how to make a miter box yourself and how to make a corner on the ceiling plinth clearly. Following the rules I described, you can easily solve this problem. If you have any questions, ask them in the comments. And clearly the algorithm of actions will be demonstrated by the video in this article.

Renovation of the premises and its interior decoration most often ends with the installation of ceiling plinths. Although some people prefer to refuse them, but even if the most professional master will make interior decoration accurate to the millimeter, the repair will seem incomplete if you do not glue the ceiling plinth. When you are doing cosmetic repairs, most likely, against the background of other questions, there is another problem - how to cut the corners of the ceiling plinth?

A ceiling plinth completes the interior decoration, giving the room a neat finished look.

Some features

Initially, everything seems extremely simple. In real repairs, people who are faced with sharp corners find that everything is not so simple as it seemed initially.

This problem arises because you cannot cut the ceiling plinth at a 45 degree angle. How to cut a corner of a ceiling plinth if there is no certain knowledge and experience? Let's try to answer this question.

To know the technology of working with a certain material, it is necessary to determine the properties of this material. To do this, we will find out, but what are such products made of? Materials for making:

To work you will need the following materials:

1. Miter box. This carpentry tool is sold in all hardware stores. Choose the simplest option so you can cut at 95 and 45 degrees.
2. Hacksaw for wood or metal. When choosing this item, take one with small and frequent teeth. In this case, the cut will be even and smooth.

But sometimes there is no way to buy a miter box. Therefore, we will consider two options for how to cut the corners of the ceiling plinth:

• without a professional miter box;
• with a miter box.

Cutting the corners of the skirting board with a miter box is as easy as shelling pears!

Fitting the skirting board on site before gluing is a mandatory step in the quality work of installing the ceiling skirting board.

If you bought a miter box or you already had one, then cutting corners will not be difficult. In order for the angle to turn out to be even, it is necessary to lay the plinth in the miter box in the position in which you will further attach it to the ceiling.

Hacksaw or knife? For a tree - just a hacksaw, for the rest you can use a knife, but only on condition that it is sharp and thin. Otherwise, you risk ruining the baseboard.

Once the cut has been made, it may be necessary to adjust the angle before mounting. This is done with a file - for wood, for expanded polystyrene and polystyrene - with a sharp knife.

Cutting a ceiling plinth requires softness, tenderness, smoothness and serenity.

Do not use force at all, as this can break not only the fragile foam, even the tree can crack if you press harder than necessary.

Cutting the corner of the skirting board without a miter box is also not a problem!

But it is not always possible to buy a miter box (not in material terms, it is relatively inexpensive). There are cases of repairs in the country, when they initially forgot to buy, and a trip to the city will cost more than the miter box itself. Therefore, consider the next option - how to cut a plinth without a miter box.

1. For this option, you will need a simple pencil, eye gauge, knife or hacksaw for metal (or wood). Find a tray that is similar in shape to a miter box. This will be an analogue. You can even choose the angle between the wall and the floor. First, mark the places on the material where you will make the cuts. Further, the work is similar to the work with a miter box. Lay the product in such a position in which it will be mounted on the ceiling. Holding a knife (or hacksaw) strictly in an upright position, make cuts along the intended meters. Tip: Use a protractor or a student's ruler for correct markings.
2. Another method requires cardboard or thick paper. A template is made of cardboard, a line is drawn in it with a simple pencil - a landmark. After that, take two small boards and assemble them at a 90 degree angle. Further, the process is the same as with the miter box. Lay and start cutting the ceiling plinth in the direction of the selected corner.
3. The third way to cut ceiling plinths is also quite simple. The method is similar to the first two - an analogue of a special construction miter box is also made. Take 3 boards and hammer them in the position that the miter box suggests. Take the student's protractor and draw 45 degree angle lines. Further, everything is as with a regular miter box.

Additional rules

With the help of the above tips, it becomes clear that cutting the corners of the baseboard for the ceiling is not difficult. But in order for the result to be of high quality, it is worth familiarizing yourself with some rules:

1. Before attaching one part, it is worth adjusting the second. Before applying glue and fixing the product directly to the wall, attach both halves of it. In this case, the surface of the wall must be dry. So, you will check that the connection is correct so that there is no gap and gap. In case of mismatch, trim the joint with a sharp knife.
2. Don't be nervous if it doesn't work right away. It's quite normal. Sometimes for proper cutting it is necessary to trim the element several times.
3. It happens that the vertices coincide perfectly, and there is a small gap in the middle. Such an angle can be fixed, then the gap can be sealed with a putty. This is not scary, since the plinth must be painted after installation with water-based paint.
4. Particular attention should be paid to the length of the planks in the corners. The following rule applies here - for the inner corner, the length of the bar is adjusted from corner to corner. The outside corner is measured in the direction of the room from the inside point.

In the course of consideration, it is clear that cutting the corners of the ceiling plinth when there are only the most basic tools, such as a knife, a hacksaw and a miter box, is quite simple. You can save a little money and do without the help of a wizard.

If it is already very difficult for you to cut, you can buy ready-made parts to which straight strips are attached. Basically, it all depends on your abilities, skills and, most importantly, patience. Good luck!

• Adjusting skirting boards to any angle
• Installation of ceiling plinth

Every owner wants to see his house in perfect condition after renovation, but the seams in the corners of the ceiling can ruin the impression of the new interior. To prevent this from happening, ceiling plinths were invented.

When choosing a skirting board, you should pay attention to the material from which the skirting board is made, as well as the color and width.

Adjusting the skirting board is not very difficult, but, nevertheless, this process has its own difficulties. There are only two of them - these are uneven walls and corner joints. If the first one is overcome quite simply, then the second one often has to tinker with.

1. Square.
2. Stationery or construction knife.
3. A hacksaw for wood or a jigsaw.
4. Metal ruler.
5. Miter box.
6. Ceiling plinth.

Scheme of marking the left strip of the inner corner.

In order to properly fit the skirting boards, you will need whole line tools, most of which are in every home.

The process itself is not very laborious, but it requires the utmost precision of execution. The seam at the corner of the joint should not be just flat, but perfect. It is simply necessary so that it cannot be seen.

Often it is necessary to resort to a double joint of skirting boards at one corner, especially in cases with external ones, but if done correctly, this will play an extremely positive role, because the corner itself will visually round off. All work is divided into several stages.

Check all ceiling corners for dust. The working surface must be dry and clean so that the skirting board is tight enough and then does not peel off until the owners themselves want to remove it.

Using a square, the angle is measured. And happiness if it is 45 degrees, tk. in this case, it will be possible to use a miter box (a tool that allows you to cut flat objects from plastic to metals at an angle of 45 degrees), if the angle is different, you will have to navigate in place, but the joint should be made strictly along the bisector.

Styrofoam and light plastics are perfectly cut with a clerical or construction knife, while denser materials will have to be cut with a small hacksaw for wood or with a jigsaw with the smallest nozzle. To do this, the plinth is fixed in a miter box or any other improvised rack-clamp, and in the first case, a cut is made with one movement, and in the other, a careful cut is made.

Scheme for trimming ceiling plinths in a miter box for arranging external and internal corners.

After the completion of the previous stage, the plinth is applied to the corner again and based on the results obtained, the markings are made on the next one.

This will make the joint as tight as possible. If, after cutting from the second ceiling plinth, it turned out that it was not cut, then it will simply remain to trim both sides. But at outer corners, there are often situations when there is an extra cut and a gap is obtained.

To rectify the situation, exactly as much is cut from the first sample as needed to obtain an identical deviation from the corner. And a narrow strip is inserted between them, which at the same time closes the flaw and harmoniously rounds the corner of the ceiling plinth - this option is used by many on purpose, because in most cases, it comes in handy for the interior.

Back to the table of contents

Putty will help to close the joints between the skirting boards. The paint will be perfectly applied to it.

When everything is cut, you can start gluing. For some materials it is better to use glue, for others - silicone sealant, for work with the third, both are suitable. After gluing, the last fitting of the skirting boards takes place, where the fillets are correctly aligned and each corner falls into place.

The very last stage of the work will be the filling of the cracks in the corners, walls and ceilings that remain. For this, an acrylic putty is used, which is carefully applied around the entire perimeter of the ceiling plinth. When applying, it is important to take into account that accuracy is important here, and work done correctly without hitting the walls and ceiling in the end will be invaluable.

After the ceiling plinth is fully fitted, glued and greased, and the corners are seam to seam, it should be left unwavering for a while. In the very near future, it will dry up and take on the state to which they tried to adjust the whole process. During operation, you should try not very often to influence the skirting board with wet cleaning, because many species are very afraid of this, deform and lose their appearance.

Correctly forming the corners of the ceiling plinth is very important: this finishing element is always in sight.

Poor docking can ruin the impression of the renovation. But this is not a simple matter: cutting the plinth at 45 degrees, you will not get the desired result (there will be gaps). For your attention, expert advice on how to saw down the corner of the ceiling plinth.

Trimming should be carried out along the outer edge of the skirting board, as well as from the inside (when forming an outside corner) or front side (for internal joining).

If everything is done correctly, the texture of the cornice will not be disturbed. At home, styrofoam finishing materials are most often used. The technology for joining the elements is as follows.

1. The angle between the walls is measured with a protractor. In the event that it is strictly equal to 90 °, the edges must be cut at 45 °. The action is performed on both elements.
2. If the joints between the ceiling and walls are not even, the corner radius should be halved. In this case, the baguette, which will be attached on the left side, is cut off on the right, and the right element, respectively, on the left.
3. The edges of the inner corner pieces are trimmed so that the top is shorter than the bottom. The edges of the outer corner are formed differently: the lower part is shorter than the upper one.
4. Unlike Styrofoam skirting boards, wooden parts need to be precisely adjusted to each other and to adjacent surfaces, applying and cutting along the abutment line.

What tools can be used to cut corners

1. It is convenient to cut corners using a miter box and an electric miter saw. Small amounts of work can be done with a hand-held hacksaw with fine teeth.
2. If it is necessary to change the direction of cutting, use a jigsaw.
3. You can cut a narrow polystyrene skirting board using a construction knife or a metal hacksaw.
4. The markings on the plinth are applied with a simple pencil, the traces of which are erased after installation.

How to cut a plinth without a miter box

Let's say you urgently need to glue the ceiling plinth.

How to make a corner without a miter box? This is possible, although it will take more time. You should proceed in this order.

1. Both skirting boards are cut at right angles at first.
2. The position of the elements on the wall is marked and the line of their joining is drawn. As a result, we will see two intersecting lines. The point of their intersection is projected directly onto the skirting board details.
3. The plinth is applied to the ceiling and a cutting line is drawn from one edge to the other.
4. Refinement of parts is carried out with a clerical or construction knife.
5. A virtual miter box is depicted on paper with lines drawn at the desired angles. The fillet of the plinth is applied to such a miter box and cutting is performed (while the knife blade should be held vertically).

How to cut the corner of a ceiling plinth: a video with expert comments will help you deal with this problem.

Advice! Since the inner or outer corner does not always have an ideal shape, the ceiling plinth will have noticeable gaps at the joints.

To make them less noticeable, plaster putty should be applied to its ends before gluing the plinth. After joining the elements, remove the excess putty with a rubber spatula. All gaps will be filled and the joint will be less visible.

Do not just glue and correctly dock fillets with the pattern. What should you do in this case? The video will tell you the answer.

Docking skirting boards using decorative corners

In the event that the walls are ideally prepared, and the external and internal corners are 90 °, it is possible to use special decorative elements for joining the fillets of the plinth. The advantages of this method:

• ease of installation: there is no need to "fill your hand", improving the technique of trimming plinth parts;
• saving time: to join the elements, you just need to cut them at right angles and attach the decorative part.

The decorative parts themselves for joining fillets are intended for:

• for internal corner joints;
• for external (external) corner joints;
• for connecting straight parts.

This connection method is the only option in the case of installing a plastic skirting board, which cannot be trimmed without gaps.

Covering the joints of ceiling plinths

No matter how carefully the work is done, the joints between the fillets of the plinth will be noticeable. This defect can be eliminated as follows.

1. Glue is applied to the joints of the skirting board.
2. After connecting the elements, remove excess glue with a clean cloth. Do this after the glue has completely dried.
3. The gaps between the plinth, ceiling and wall are trowelled with a mixture of plaster putty and water-based paint using a rubber trowel.

This method is suitable for masking defects when connecting wooden baseboards, as well as fillets made of polyurethane foam, polystyrene foam, polystyrene foam. In some cases, a white sealant can be used.

Using the tips outlined in the article and the necessary tools, you can cut and join the fillets of the ceiling plinth yourself.

Correct trimming of the ceiling plinth - how to do it?

Ceiling plinth is a decorative border between walls and ceiling. But it is often used to mask the joints of the finishing material on the wall and on the ceiling, if it is not done neatly, or has a different structure.

Many people ask themselves the question: how to properly cut the ceiling plinth, because without it, the design of the room seems unfinished.

This element is simply glued - on special glue. But trimming the ceiling plinth in the corners to make them look presentable and tidy can confuse some. There are rooms with a complex layout, in which you need to equip not only internal corners, but also external ones.

This question can be answered exactly if you know what material this decor element is made of. There are four types of fillets:

• polyvinyl chloride (PVC);
• polyurethane;
• expanded polystyrene (polystyrene);
• wood.

The cheapest option is foam skirting boards. But this is a very delicate material, creases and dents can appear on it, even from the fingers, if you press it harder, so it is very difficult to carefully cut the corner of the ceiling plinth from this material.

In most cases, an inexperienced person throws away a lot of material for this reason.

They are electrostatic and attract a lot of dust. They are cut with an ordinary clerical knife. You can also cut it off with a fine-toothed hacksaw, but there is a chance of getting an uneven edge.

Polyvinyl chloride is one of the inexpensive materials, it is brittle and can crumble when cut. You can cut off the ceiling plinth from this material with a sharp construction knife, or a hacksaw for metal.
You need to try not to apply force when cutting, when pressing, you can get a chip.

The polyurethane skirting board is more expensive than the first two options, it is much denser and tougher, and it is difficult to cut it.

But there is a plus - when pressed, it does not crumble. It is better to cut it with a hacksaw for metal, but a sharp construction knife may work. The corner of the skirting board made of this material is smooth and neat.

This decor option is currently the most expensive. It is durable, moisture resistant, elastic.

But fillets have a big drawback - a reaction to temperature changes. For example, in the kitchen above the stove, it can crack and deform, and it is almost impossible to process it, all that remains is to replace it. But this is not a panacea, it will crack again.

Wooden plinth is a natural solid and rather heavy material, which cannot be attached to glue. Cut it off with a hacksaw with a small blade, preferably for metal. This will make the edge of the trimmed skirting appear smoother.

These are corner pieces that are commercially available.

Having bought fittings for corners, the skirting board itself can be cut to size, at an angle of 90 degrees. The corner element is glued to the corner, and the fillet itself is attached to it. So you can hide all the flaws.

But it is not always possible to use fittings - it is much larger in size than the fillet itself, and the corners in such an interior stand out strongly, and this is not always aesthetically pleasing.

If this is not a matter of principle, then of course it is better to buy a corner element and not bother with cutting corners.

We decided to cut the skirting boards themselves, then use some tips on how to do it correctly.

Docking technology:

• Measure the degree between the walls using a protractor. 90 degrees, then cut to 45. If it is different, then we divide its value in half. Both elements are trimmed.
• The skirting board, which will be fixed on the left side, is trimmed on the right, and the right molding on the left side, respectively.
• The cuts of the inner corner parts along the edges should look like this, the top line is shorter than the bottom one. Outer - on the contrary, the lower line is shorter.
• If the foam plinth in the corners can be corrected, then with wooden parts this will not work and they will have to be adjusted very precisely until they are completely abutted.

A carpenter's tool that allows you to cut workpieces at different angles - miter box. This is a tray in which there are slots made at a certain angle. The material from which it is made can be different, for example:

A simple design has two types of angles 45-90 degrees, a complex configuration 90-60-45 degrees. The second type of tool is considered professional.

Let's consider how to cut a ceiling plinth using a miter box:

1. First you need to measure the required length of the plinth, for this we attach it to the ceiling.
2. The measured bar must be inserted into the miter box at a certain slope in the same position as on the ceiling.
3. We move the bar to the opposite wall of the apparatus.
4. We press well with the left hand.
5. The position of the hacksaw handle should be as close as possible to the left hand, and the angle will be 45 degrees.
6. Saw the plinth carefully, without pressing.

One plank is ready, now you need to cut off the opposite plank:

1. We put it against the wall of the miter box, but only on the opposite side.
2. We hold it with our right hand, pressing it against the wall.
3. You will have to saw with your left hand, but the hacksaw should be in the same position, only in a mirror image.
4. Cut off

Docking check - consists of one hundred need to attach the trimmed strips to each other at the corners. For precision, it is best to start trimming from the front of the skirting board. If we are talking about a tree, then the angle will have to be adjusted with a file.

Outside corner

1. If the bar reaches both corners, then first we cut the inner corner, and then the outer one. It may turn out that after trimming the corner, the plank will not be enough.
2. As in the first case, we apply it to the ceiling to mark the dimensions.
3. The plank must be positioned so that it is pressed against the near wall.
4. We hold it with our left hand and put the hacksaw in the 45 degree position - the handle is close to the left hand.
5. Cut off.
6. We set the second bar in the same way, but we only hold it with our right hand.
7. The hacksaw becomes a mirror image to the first option for trimming the skirting board.
8. We cut it off.

It is worth noting that the miter box will be useful to you only if all angles in your apartment are equal to 90 degrees. When the corners are not even, you will have to use other trimming methods.

As you can see, it is not difficult to cut off the ceiling plinth correctly with a miter box.

The markings on the ceiling will also help to cut the bar to the nearest millimeter. This is not easy to do, since when trimming, the plinth strip will have to be kept suspended. But, this is the most accurate way to adjust the angle on the skirting board.

By attaching the plinth to the ceiling, you can see all the irregularities on the wall. Angle deviation is also visible and must be taken into account when trimming.

In order to cut correctly you need to:

1. Make a cut to the workpiece 90 degrees.
2. Attach the workpiece to the ceiling and outline its contours. In this case, it is necessary that it fit snugly against the perpendicular wall.
3. Then we do the same on the adjacent wall, outlining the outline of the workpiece along the ceiling.
4. We put a point at the intersection of the lines, this will be the reference point by which the corner of the plinth will be trimmed.
5. On each workpiece, alternately mark a cut point that coincides with a point on the ceiling.
6. From a point to the opposite side, draw a line at an angle, along which it will be necessary to cut the plinth.

Once the markings have been completed, you can properly cut the skirting board and try it on. It is worth noting that this method involves trimming with inside blanks.

To trim the skirting board, you can make a miter box template yourself. It is made of cardboard, paper, or wood. The principle is this:

• draw two parallel lines;
• we define the center;
• we apply the corners with a protractor.

A very handy device, as it allows you not only to cut corners of 90 degrees, but also higher. But before doing it, check the corners on the ceiling, suddenly they are uneven, and then the workpiece imitation of the miter box will have to be adjusted. Since it will not be possible to cut the plinth exactly.

You can cut off the corner according to the drawn template in the same way as when using a real miter box. Only in this situation will we press the bar against the drawn, parallel lines.

There is a rule according to which you need to cut the ceiling plinth:

• To mark the inner corner, measurements are taken from the corner.
• For the outer corner, you need to know that the ceiling plinth will protrude into the room for a length equal to the width of the workpiece.

Do not glue the skirting board until both planks have been prepared and tried on. Once the planks in the corner have come together perfectly, you can spread them with glue and secure.

If there are flaws in polyurethane or wood baseboards, then they are processed with a small file. WITH plastic skirting boards you can get by with a sharp clerical or construction knife.

There is no need to despair if there is a gap in the corners after fitting, it can be masked with a white putty. To do this, even before fixing the second plinth, which will be joined in the corner, putty is applied to the joint.

After the corner is fixed and pressed, the excess mixture must be removed and the corner wiped with a damp cloth. If necessary, you can paint the joint with water-based paint for ceilings.

How to mask joints

With any neat work, there are flaws, and installing a ceiling plinth is no exception, especially if you are doing it for the first time and have no idea how to neatly cut ceiling plinths. Flaws and defects can be removed like this:

• The glue is applied to the joints, with which the skirting boards are attached.
• As soon as the glue dries at the joints, it is enough to wipe it off with a clean cloth.
• As for the gaps in the ceiling area, they are clogged with putty and painted over with paint. This should be done carefully with a rubber spatula.
• If there is a white sealant at home, then you can use it to seal the cracks, then you will not have to paint the joints.

In custody

As you can see, the lesson on trimming the corners of the ceiling plinth is not difficult, and anyone can master it.

Do not start right away by cutting corners on a whole plank; practice on small elements. And as soon as you start to work out, move on to a solid baseboard. We hope you learned from this article how to properly trim the ceiling plinth in the corners.

How to cut a ceiling skirting board? At first glance, it seems that such a problem does not exist at all. However, the very first attempt to lay in the corner zone leads to defects in the form of ugly gaps, mismatches. Every job requires a thoughtful approach, and skirting board installation is no exception. By itself, this event can hardly be attributed to complex construction operations, but without taking into account some of the nuances, it is very difficult to ensure the ideal quality. The question of how to cut a ceiling plinth is completely solved independently, but this must be done correctly and accurately.

The ceiling plinth is a decorative strip and gives the renovation a finished look, so you need to know and be able to work with it correctly.

Features of the ceiling plinth

Ceiling plinth, or fillet, is a decorative strip that visually separates the ceiling from the wall, as well as masking the joint areas finishing materials and flaws in the corner joint between the wall and the ceiling. Such an element can be made of wood, PVC, polyurethane, polystyrene foam, extruded polystyrene foam, gypsum and have different widths.

Figure 1. Installation diagram of the ceiling plinth.

Fastening the fillet to the wall is carried out by gluing with a special adhesive and does not cause difficulty when installing with your own hands. The most difficult areas are the inside and outside corners. High-quality installation provides for a clear articulation of the bar in the corners without a gap, which sometimes causes problems. When forming corners on embossed, curly decorative skirting boards, it is better to use special overhead corner pieces that allow you to ideally close all cutting defects. The cutting of the material itself is easily done with a sharp knife or a hacksaw for metal.

Figure 1 shows the options for performing corners when installing a fillet. The overhead corner simplifies installation. When installing it, the part is simply measured along the length of the wall, and its end is cut at a right angle. The overhead element hides all the gaps underneath, but protrudes somewhat beyond the borders of the plinth, drawing attention to itself. For all the decorativeness of such details, not everyone likes their visibility, and therefore the direct joint of the planks without additional elements is more popular. (Fig. 1. Scheme of installation of the ceiling plinth)

When forming external or internal corner joints from two fillets, their ends should be cut strictly in a given direction so that a gap does not form at the joint. The problem includes the following conditions: ensuring that the corners on both elements match, maintaining the same cut across the entire width of the skirting board and ensuring a strictly vertical cut. Any violation of the conditions leads to the appearance of a gap either over the entire width of the bar, or in certain areas. The task becomes more difficult as the width of the element increases.

Cutting with a miter box

In order to qualitatively solve the question of how to cut the corners of the ceiling plinth, there is a fairly simple carpenter's tool - a miter box. This tool is designed as a wooden, metal or plastic tray with vertical slots for cutting in different directions. The fixture usually has slots at 45, 60 and 90º. In more complex structures a tilt change mechanism is provided, which allows you to set any required cutting angle.

Figure 3. Diagram of cutting a corner using a miter box.

Fig. 2 shows a standard miter box, and Fig. 3 shows the principle of its operation. Plank ceiling element is installed on the bottom of the tray with the side joined to the ceiling during installation and pressed against the wall with the right slot. A hacksaw for metal is inserted into the slot, and with neat, smooth movements, the plinth is completely cut. The second fillet is cut using the left slot. (Fig. 2. Standard miter box) (Fig. 3. Diagram of corner cutting using a miter box)

When arranging a standard inner corner of two adjacent walls, fillets are cut at 45º. This is the most common cutting. The outer corner is made, if necessary, to bypass the protrusions or niches on the wall and is formed in the same way (Fig. 3). Sometimes niches or ledges have a trapezoidal appearance - in this case, adjacent piers are joined at an angle other than a straight line. In this case, the skirting board is cut at an angle equal to half the angle of the wall joint. For this, a cut angle of 60º is provided in a standard miter box (when joining walls at an angle of 120º).

The miter box can be done very simply with your own hands. For this, a wooden tray is assembled from slats 15-20 cm thick, while the height of the tray should not be less than the fillet width. Using a protractor, an angle of 45º is set, and using a hacksaw, both vertical walls of the tray are completely cut. Perpendicular to the line of this cut, a line is drawn through the center of the tray along which another cut of the walls is carried out. Cutting the skirting board on such homemade device carry out similarly to the standard miter box.

Cutting skirting boards without a miter box

You can cut the ceiling plinth even in the absence of a miter box. What if you don't have a fixture at hand, but you only need to cut a few baseboards? You can form a neat corner without using a miter box. The easiest way is the attachment method. Taking into account the actual unevenness of the corner joints, it is better to carry out it directly at the installation site of the fillets.

Corner cutting is carried out in the following order. First, the planks are measured strictly according to the size of the walls (from corner to corner) and cut at right angles. Then the first fillet is placed end-to-end against the adjacent wall and held in this position. The second plank is set perpendicular to it, pressing against the wall. On the first fillet, a line is drawn along the edge of the docked second fillet. On both side faces, a drawn line connects to the bottom corners of the plank. The marking of the second plinth is carried out in the same way. Cutting is carried out strictly according to the marking.

The markings can be carried out in the lower corner of the walls, but during installation, the presence of real deviations may appear at the junction of adjacent walls in the upper corner, which will cause certain inaccuracies.
