How to cut plastic skirting boards. How to properly cut ceiling plinths in corners? Types of ceiling and floor skirting boards, selection of tools

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

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

Cutting ceiling plinth

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

Trimming wooden plinths is done with a regular hacksaw.

What is a miter box?

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

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

Trimming ceiling plinth in a miter box

Trimming in a miter box is performed as follows:

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

How to make a corner of a ceiling plinth

Important: When pruning, remember that when decorating internal corner The edge of the plinth adjacent to the wall should be longer than that adjacent to the ceiling. When finishing the exterior, it’s the other way around.

A second ceiling strip is inserted into the tray from right to left and cut;
The finished planks are placed at the corner and the joint is adjusted using a knife;

The planks are placed on the corner and adjustments are made

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

How to cut baseboard:

What to do if there is no miter box?

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

In the first case, the procedure is as follows:

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

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

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

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

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

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

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

In order to cut an even angle, you can also use an imitation of a miter box:

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

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

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

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

How to connect planks if the corner is uneven

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

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

An uneven angle can be measured using a small protractor

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

How to clean up corners

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

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

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

Corner elements for ceiling plinths

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

When using corner elements, strips are cut at right angles

How to properly trim floor plinths

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

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

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

The strip is inserted into the tray and pressed tightly

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

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

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

How to cut ceiling plinth for external and internal corners

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

Thus, we have looked in detail at how to cut plinths in corners. The procedure is not as complicated as it might seem at first glance. Once you start pruning in a miter box or using its imitation, you will see this for yourself.

Specialization: master of internal and exterior decoration(plaster, putty, tiles, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, renovations in an apartment or house were done on a turnkey basis with all necessary types works

The question of how to cut plastic skirting boards can be answered quite concisely and unambiguously by pointing to a hacksaw for metal, but this will still not be entirely accurate information. After all, by and large, in this question there is a subtext that points to the full action, and not to the tool itself, so that without a full familiarization with the process, the purpose of a particular tool is difficult to understand. Therefore, I want to tell you about my own experience gained over years of practice, and in addition, you can watch the video in this article.

Cutting corners of floor and ceiling skirting boards

In Russian, plinth means decorative strip, covering the junction of the wall and the floor (ceiling).
This name comes from the Greek πλίνθος and Latin plintus.

Tools and accessories

Let's start with the fact that cutting plinths at an angle of 45⁰, 90⁰ and others can be done by anyone cutting tool, but here, as elsewhere, there are preferences:

the most convenient tool, which leaves behind the most high-quality cut, you can call it a hacksaw for metal, and this applies not only to plastic fillets, but also to fillets;
due to the fact that the blade has fairly fine teeth, the cut is clear and, most importantly, accurate, which is important for joining profiles - the more precise its processing, the better the joint, since there will be no gaps there;

Of course, as we have already said, the instructions do not indicate this or that tool in mandatory so for plastic you can also use a construction knife;
there are options here, since these knives are similar in that they have a removable blade, but at the same time it can be different thicknesses and length (for wallpaper, as in top photo or for drywall);
but in these cases such a tool is only suitable for thin-walled profiles– polyurethane, for example, cannot be cut with it.

For precision in fitting joints, a miter box is often used for cutting skirting boards, which can be different:

the difference in the design of such a tool lies in the complete or incomplete presence of all grooves for corner cutting;
a tool with a full set has grooves at a slope of 45⁰, 60⁰, 67.5⁰ and 90⁰ (its price is not much more), while for a simplified tool everything comes down to 45⁰ and 90⁰;
In addition, a full-set miter box, as in the top photo, has grooves for cutting boards, that is, here you can easily cut a profile in the form of a flat strip.

What it looks like in practice - method one

So, cutting the corners of a ceiling plinth (or floor) first of all comes down to the right direction slope, since the joint can be internal or external, depending on the configuration of the angle. Let's figure this out using the image above - there, on the left and right, two opposite options are indicated - the redundant (deleted) parts of the profile are shown in red.

If we are decorating a ceiling, then the option on the left is suitable for the outer corner, and the one on the right is suitable for the inner corner. For floor decoration, everything will be identical, but exactly the opposite - there will be an internal corner on the left, and an external one on the right. Shown in the middle between the options correct position processed profile.

If you use a carpenter's miter box, then cutting corners should be done at the side of the tool closest to you!

Method two

But, as you have seen, the number of grooves for cutting corners is limited even in a miter box with a full set, which makes such a tool in some cases simply useless. The fact is that in houses you often have to deal with the fact that rooms do not have right angles, therefore, a slope of 45⁰ for joining will not suit you, since after such a connection there will be a gap.

But there is a way out, and it’s quite simple - you can mark the profiles with your own hands.

Let's look at how to fit a joint in the inner corner without using a miter box and to do this, install the profile close to the adjacent wall, and draw a line along the ceiling, as shown in the top photo. We perform exactly the same operation on the other side, as a result of which we get two crossed control lines, where the intersection will be the starting point for the cut.

The lower point will correspond to the angle at which the two walls meet - the cut line is highlighted in red in the image.

If the corner is external, then the intersection of the marking lines will naturally be further, and for this you will need not to rest the profile against the adjacent wall, but to push it beyond it in order to extend the line. You will need to perform similar marking steps for the floor plinth, only it will all look like a mirror image, on the contrary.

When cutting ceiling plinths (floor) without a miter box, manually, the hacksaw should be directed to the center of the corner, that is, its slope will be approximately 45⁰.

Method three

In the same way, with a slope, you need to cut the profile to build it up on straight sections of the ceiling or floor, and if you cut the strip at 90⁰ or even 45⁰ for this, a gap will be visible. Therefore, in such cases, you can use a miter box with grooves of 60⁰ and 67.5⁰, that is, the length of the cut should be at least twice as large as its cross-section.

This method minimizes the appearance of a gap at the connection as much as possible; in any case, it is almost invisible unless you look closely at this place.

But no matter how hard you try when marking and cutting skirting boards, the human factor can always come into play - even the best masters and an error of a fraction of a degree is possible, which will cause a small gap. If you are dealing with plastics, then in such cases this error can be very easily repaired with silicone, and for other materials - with wood putty or plaster, respectively. In some cases, even a coat of paint is enough to seal.

Conclusion

In conclusion, I would like to say that the cutting tool itself will be of paramount importance, but how you do it, that is, how correctly you mark the cut and how accurately you adhere to the approximate lines. But if something remains unclear to you, ask your questions.

At the final stage of arranging the floor, the contact points finishing coating the walls of the room are usually covered with skirting boards. Most popular in Lately purchased plastic products. They are not only aesthetically pleasing and varied, but also very functional. The question of how to cut plastic skirting boards arises for everyone. home handyman who encountered this procedure for the first time. The tools and devices for carrying out such work are quite simple and quite affordable.

Advantages of plastic products

Compared to their counterparts made of wood or MDF, plastic skirting boards have a number of advantages. Their undoubted advantages include:

Durability and strength.
Moisture resistance. They are suitable for installation in rooms with high humidity(bathrooms, showers and toilets).
They do not need to be painted or have any other protective coating applied.
Presented on the construction market huge selection colors: from a variety of solid colors to those imitating the structure of expensive wood. It is easy to choose fillets for any interior design of the room.
Easy to process and attach to the wall.
Convenient aftercare. The only limitation: it is unacceptable to use abrasive cleaning agents that can scratch the top decorative layer.
Affordable price.
Safety for human and animal health. All modern polymer materials for this purpose are manufactured in strict accordance with sanitary standards and requirements.

Varieties

There are several types of plastic floor skirting boards depending on the material of the finishing coating:

Special T-shaped profile for framing carpeted floors. To decorate such products, strips cut from the floor covering itself are used, which are secured with double-sided tape.

L-shaped products specially designed for fixing linoleum to walls.

Universal, which are suitable for floors of the most various materials(from tiles to laminate or parquet boards).

According to their functional features, such products are:

with a cable channel equipped inside the fillet(one or more) for laying wires for various purposes(telephone, antenna, computer or electrical).

with pressed rubber strips along the edges for a tight fit to walls that have roughness and unevenness.

The choice of geometric dimensions is also quite wide. The width of the fillet, which is usually chosen, is commensurate with the height of the ceiling of the room; it can be from 40 to 150 mm. The standard length is 2 or 2.5 m. The thickness of the profile in the lower part, depending on the design, is in the range of 10÷38 mm.

Tools and accessories

When arranging the finishing floor frame, any home craftsman reasonably has three main questions:

What to cut
How to do this carefully and at the required angle?
How and with what should I secure the cut pieces to the wall?

You can cut long products into separate parts of the required length using:

grinders (with a thin cutting disc installed);
electric jigsaw;
manual or with fine hardened teeth).

The final choice of what to use to cut plastic skirting boards depends on the tool you already have, personal preferences and experience.

To securely fix fillets to the walls of the room you will need:

a hammer drill (with a drill of the required diameter) or an electric drill (with impact mode);
set of dowels and screws;
screwdriver or screwdriver (to save time and effort).

To accurately saw off pieces at the desired angle, you will have to purchase a miter box (of course, if you don’t have one on the farm). It’s impossible without him.

Miter box: varieties and methods of use

A miter box for cutting plastic skirting boards is special device, designed for accurate cutting at a certain angle. The simplest products are made of wood or plastic. In geometric shape, they represent a segment of an inverted U-shaped profile. The side walls have narrow cuts for hacksaw blade. Until recently, the most common devices were devices with three cuts, allowing the end of the plinth to be cut at angles of 45° and 90°. However, the layout modern apartments is very diverse and often there is a need to equip different corners of the premises. Therefore, manufacturers produce products with a large number of slots designed to install the hacksaw blade at different angles.

The price depends on the size and material of the device. Thus, a plastic device from Stanley with a length of 310 mm, a width of 130 mm, a side height of 78 mm and the ability to saw at angles of 90°, 45° and 22.5° now costs 750-800 rubles.

The application algorithm is quite simple:

Using a marker and ruler, mark the cutting line.
We press the profile tightly against the vertical wall of the device so that the markings clearly coincide with the installation location of the saw.
We carefully saw off.

You can cut plastic skirting boards with a hacksaw. This tool has its advantages: small cutting teeth and a slight gap. However, the low longitudinal rigidity of a narrow hacksaw blade can negatively affect the quality of the processed surface. It is better to use special ones for this (with a wider and stiffer blade). The hardened teeth can easily cut through plastic.

More complex designs They are a base with clamping clamps (for fixing the workpiece). The kit already includes a saw mounted on special guides. The cutting angle can be adjusted within a wide range. The materials used to make the base are metal or impact-resistant plastic. But such devices are already more expensive. Thus, popular rotary models from Gross or KWB with a double-sided saw (size and sharpening of teeth for various materials), depending on the size, already cost 2200-4700 rubles.

Using such devices is very simple:

set the required angle;
We press the fillet to the frame using clamps, so that the markings are strictly under the saw blade;
we make a cut.

And even if you decide to renovate only one room, then you should think about renting such a device and not worry about how to cut a plastic baseboard. Ease of use, speed and quality of processing will fully repay the money spent.

How and with what to fasten

The simplest, least labor-intensive and quite reliable way fastenings - use of universal quick-drying adhesive compositions type "liquid nails". The disadvantages of this method include:

When dismantled (if necessary), the product will most likely be damaged, so initially it goes into the category of “disposable”.
The inner surface of the fillet must have a wide enough flat strip to allow application. required quantity glue.

If the supply of a plastic skirting board for the floor includes fastening elements: metal (or polymer staples) or special long profiles, then first they are fixed to the wall using dowels and self-tapping screws. Further installation is quite simple. The product is carefully snapped onto the already secured fixtures. The advantages of this method include: the possibility of repeated dismantling (this is especially convenient when changing wallpaper: the bottom edge wall decoration you can get it behind the baseboard).

The presence of a cable channel with a decorative outer strip allows you to simply screw such a fillet to the wall through pre-drilled holes.

Joining individual sections

When installing polymer fillets, they must be reliably and at the same time aesthetically joined at the corners of the room being equipped, and sometimes on a straight section, along long wall. The best solution The question of how to join the skirting boards is the acquisition of the required number of special products. Almost all manufacturers of products for floor covering edging produce these small, but very convenient and necessary “parts” of various geometric shapes:

for arranging internal and external corners;
for horizontal joining of straight sections;
for sealing ends.

These devices are either simply snapped onto the ends of the profile using special antennae; or at the places where they are installed, brackets are attached to the wall, and then the connecting elements are fixed to them.

Adjustment of ceiling plinths to any angle
Installation of ceiling plinth

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

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

Adjusting the ceiling plinth 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 be tinkered with.

Square.
Stationery or construction knife.
Wood saw or jigsaw.
Metal ruler.
Miter box.
Ceiling plinth.

Scheme for marking the left inner corner strip.

In order to properly fit skirting boards, you will need a number of tools, most of which are found in every home.

The process itself is not very labor-intensive, but requires extreme precision. The seam at the corner of the joint should be not just even, but perfect. This is simply necessary so that it is not visible.

It is often 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 be visually rounded. All work is divided into several stages.

Checking everyone ceiling corners for the presence of dust. Working surface It must be dry and clean so that the plinth fits tightly enough and then does not come off until the owners themselves want to remove it.

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

Foam and lightweight plastics can be cut perfectly with a stationery or construction knife, while denser materials will have to be cut with a small wood hacksaw or a jigsaw with the smallest attachment. To do this, the plinth is secured in a miter box or any other improvised clamping stand, and in the first case a cut is made in one movement, and in the other a careful cut is made.

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

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

This will make the joint as tight as possible. If, after cutting off the second ceiling plinth, it turns out that it was not cut, then all that remains is to simply trim both sides. But with external corners there are often situations when there is an extra cut and a gap results.

To correct the situation, exactly enough is cut from the first sample to obtain an identical deviation from the angle. And between them a narrow strip is inserted, which will simultaneously cover the defect and harmoniously round the corner of the ceiling plinth - many people use this option on purpose, because in most cases it is very useful for the interior.

Return to contents

Putty will help close the joints between the baseboards. The paint will apply perfectly to it.

When everything is cut, you can start gluing. For some materials it is better to use glue, for others - silicone sealant, for working with others, both are suitable. After gluing, the final adjustment 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 to putty the cracks in the corners, walls and ceilings that remain. For this, acrylic putty is used, which is carefully applied along 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 a single hit on the walls and ceiling will ultimately prove invaluable.

After the ceiling plinth is completely fitted, glued and greased, and the corners are butted, it should be left for some time in an unshakable state. In the very near future it will dry out and take on the state to which they tried to adjust the whole process. During operation, you should try not to touch the baseboard very often. wet cleaning, because many species are very afraid of this, become deformed and lose their appearance.

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

A poor connection can spoil the impression of a repair. But this is not a simple matter: if you cut the baseboard at 45 degrees, you will not get the desired result (gaps will remain). Here's expert advice on how to file a corner of a ceiling plinth.

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

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

Using a protractor, measure the angle between the walls. If it is strictly equal to 90°, you need to cut the edges at 45°. The action is performed on both elements.
If the joints between the ceiling and walls are not even, the corner radius should be divided in half. In this case, the baguette, which will be attached on the left side, is cut on the right, and the right element, accordingly, on the left.
The edges of the inner corner parts are cut so that the top part is shorter than the bottom. The edges of the outer corner are formed differently: their lower part is shorter than the upper.
Unlike foam baseboards, wooden parts must be precisely adjusted to each other and to adjacent surfaces, applying and cutting along the abutment line.

What tools can you use to cut corners?

It is convenient to cut corners using a miter box and a miter saw. Small amounts of work can be completed hand hacksaw with fine teeth.
If it is necessary to change the cutting direction, use a jigsaw.
You can cut a narrow foam baseboard using a construction knife or a hacksaw for metal.
Markings are applied to the plinth with a simple pencil, the traces of which are erased after installation.

How to cut a baseboard 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.

Both parts of the plinth are first cut at a right angle.
The position of the elements on the wall is marked and a line for their joining is drawn. As a result, we will see two intersecting lines. The point of their intersection is projected directly onto the plinth parts.
The plinth is applied to the ceiling and a cutting line is drawn from one edge to the other.
Refinement of parts is carried out with a stationery or construction knife.
A virtual miter box is depicted on paper with lines drawn at the desired angles. The plinth fillets are applied to such a miter box and cutting is performed (while keeping the knife blade vertical).

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

Advice! Since it does not always have perfect shape internal or external corner, the ceiling plinth will have noticeable gaps at the joints.

To make them less noticeable, before gluing the baseboard, gypsum putty should be applied to its ends. After joining the elements, excess putty is removed rubber spatula. All gaps will be filled and the joint will be less noticeable.

It’s not easy to glue and correctly join the fillets with the pattern. What to do in this case? The video will tell you the answer.

Joining skirting boards using decorative corners

If the walls are ideally prepared and the external and internal angles are equal to 90°, it is possible to use special decorative elements to join the plinth fillets. Advantages of this method:

ease of installation: there is no need to “train your hand” by improving the technique of trimming plinth parts;
saving time: to join the elements you just need to cut them at a right angle and attach the decorative part.

The decorative parts themselves for joining fillets are designed:

for internal corner connections;
for external (external) corner connections;
for connecting straight parts.

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

Caulking the joints of ceiling plinths

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

Glue is applied to the joints of the plinth.
After joining the elements, remove excess glue with a clean rag. Do this after the glue has completely dried.
The gaps between the baseboard, ceiling and wall are rubbed with the mixture gypsum putty and water-based paint using a rubber spatula.

This method is suitable for masking defects during connection wooden skirting boards, as well as fillets made of polyurethane foam, polystyrene foam, and expanded polystyrene. In some cases, white sealant can be used.

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

Proper cutting of ceiling plinths - how to do it?

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

Many people wonder how to properly cut the ceiling plinth, because without it, the design of the room seems unfinished.

This element is simply glued using special glue. But trimming the ceiling plinth in the corners to make them look presentable and neat can be a dead end for some. There are rooms with complex layout, in which it is necessary to arrange not only internal corners, but also external ones.

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

polyvinyl chloride (PVC);
polyurethane;
expanded polystyrene (foam);
tree.

The cheapest option is foam baseboards. But this is a very delicate material, creases and dents can appear on it, even from your fingers, if you press it harder, so it is very difficult to carefully trim the corner of a ceiling plinth made of 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 stationery knife. You can also cut it with a fine-toothed hacksaw, but you may end up with an uneven edge.

Polyvinyl chloride is one of the inexpensive materials, it is fragile and can chip when cut. You can cut the ceiling plinth from this material with a sharp construction knife or a hacksaw.
You should try not to use force when cutting; if you press, you may get a chip.

Polyurethane skirting boards are more expensive than the first two options; they are much denser and stiffer, and are difficult to cut.

But there is a plus - when pressed it will not crumble. cut it better with a hacksaw for metal, but a sharp construction knife may work. The angle of the plinth made from this material is smooth and neat.

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

But fillets have big drawback- reaction to temperature changes. For example, in the kitchen above the stove, it can crack and become deformed, 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 quite heavy material that cannot be attached with glue. Cut it with a hacksaw with a fine blade, preferably for metal. This will make the edge of the trimmed baseboard look smoother.

We are talking about corner elements that are widely available.

Having purchased fittings for the corners, the baseboard 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. This way you can hide all the flaws.

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

If this is not important, then of course it is better to buy a corner element and not have to worry about cutting the corners.

If you decide to cut the baseboards yourself, 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 it to 45. If it’s different, then divide its value in half. Both elements are trimmed.
The plinth, which will be fixed on the left side, is cut on the right, and the right baguette on the left side accordingly.
The cuts of the inner corner parts along the edges should look like this, the top line is shorter than the bottom. External - on the contrary, the bottom line is shorter.
If the foam plinth in the corners can be adjusted, then with wooden parts this will not work and they will have to be adjusted very precisely until they fit completely.

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

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

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

First you need to measure the required length of the plinth; to do this, we will attach it to the ceiling.
The measured bar must be inserted into the miter box at a certain angle in the same position as on the ceiling.
We move the bar to the wall of the apparatus opposite from ourselves.
We press well with our left hand.
The position of the hacksaw handle should be as close as possible to the left hand, and the angle will be 45 degrees.
Carefully saw the plinth, without pressing.

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

We place it against the wall of the miter box, but only on the opposite side.
Hold it with your right hand, pressing it against the wall.
You will have to saw with your left hand, but the hacksaw should be in the same position, only in a mirror image.
Cutting off

Checking the joint - consists of placing the cut strips at the corners to each other. For accuracy, it is better to start trimming from the front side of the baseboard. If we are talking about wood, then the angle will have to be adjusted using a file.

External corner

If the plank reaches both corners, then cut the inner corner first, and then the outer one. It may turn out that after trimming the corner, there will not be enough strip.
As in the first case, we apply it to the ceiling to mark the dimensions.
The plank must be positioned so that it is pressed against the near wall.
We hold it with our left hand and place the hacksaw in a 45-degree position - the handle is close to the left hand.
Let's cut it off.
We set the second bar in the same way, but only hold it with our right hand.
The hacksaw becomes a mirror image of the first option for trimming the baseboard.
We cut it off.

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

As you can see, cutting the ceiling plinth correctly using a miter box is not at all difficult.

Markings on the ceiling will also help you cut the plank with millimeter precision. This is not easy to do, since when trimming the plinth strip you will have to hold it suspended. But, this is the most accurate way to adjust the angle on the ceiling plinth.

By placing the plinth against the ceiling, you will be able to see all the irregularities on the wall. The angle deviation is also visible and must be taken into account when trimming.

In order to make a trim correctly you need:

Make a 90 degree cut on the workpiece.
Attach the blank to the ceiling and outline its contours. In this case, it is necessary that it fits tightly to the perpendicular wall.
Then we do the same on the adjacent wall, outlining the outline of the workpiece along the ceiling.
We put a point at the intersection of the lines, this will be the reference point along which the corner of the plinth will be trimmed.
On each workpiece, we alternately mark a cut point that coincides with a point on the ceiling.
From the point to the opposite side, draw a line at an angle, along which you will need to cut the baseboard.

Once the markings have been made, you can properly trim the baseboards and try them on. It is worth noting that this method involves pruning with inside blanks.

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

draw two parallel lines;
determine the center;
draw the angles using a protractor.

Very convenient device, since it allows not only cutting angles of 90 degrees, but also higher. But before you do it, check the corners on the ceiling, in case they are uneven, and then the miter box imitation blank will have to be adjusted. Since cutting the baseboard evenly will not work.

You can cut a corner according to a 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 trim the ceiling plinth:

To mark the internal corner, measurements are taken from the corner.
For an external 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 baseboard until both strips are prepared and tried on. Once the planks in the corner fit perfectly, you can coat them with glue and secure them.

If there are flaws in polyurethane or wooden baseboards, they are processed with a fine file. With plastic skirting boards you can use a sharp stationery or construction knife.

There is no need to despair if after fitting there is a gap in the corners, it can be masked using 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 secured and pressed, the excess mixture must be removed and the corner wiped with a damp cloth. If necessary, you can paint the joint water-based paint for ceilings.

How to disguise joints

With any careful work there are flaws, and installing ceiling plinths is no exception, especially if you are doing it for the first time and have no idea how to carefully cut ceiling plinths. Blemishes and defects can be removed as follows:

Glue is applied to the joints to secure the baseboards.
As soon as the glue dries on the joints, just wipe it off with a clean rag.
As for the gaps in the ceiling area, they are filled with putty and painted over. This should be done carefully with a rubber spatula.
If there are any at home white sealant, then you can use it to seal cracks, then you won’t have to paint the joints.

In custody

As you can see, the task of trimming the corners of ceiling plinths is not difficult, and anyone can master it.

You shouldn’t immediately start cutting corners on a whole plank; practice on small elements. And as soon as you start to succeed, switch to a solid baseboard. We hope from this article you learned how to properly cut ceiling plinths in the corners.

Ceiling plinth is a product that in appearance is no different from its analogue floor coverings. It is also called fillet. This detail serves to mask the joints between the wall and ceiling. It is installed at the very end finishing works, since the element does not carry any functional load, but plays only a decorative role. The process of installing the product is not at all complicated, but many are faced with the dilemma of how to make a corner of the ceiling plinth. Depending on the selected materials and tools that are available, the fillet corners are trimmed different ways.

The modern construction market offers the following options for these products:

Polyurethane. They are considered the highest quality and most reliable. In addition, they are moisture resistant and elastic. Among the shortcomings it is worth noting high cost and exposure to temperature changes. Because of this feature, the corners of the ceiling plinth are made of of this material may crack if installed from below kitchen stove. It is also important to remember that inaccurate trimming may cause slight deformations, which can ultimately lead to significant curvatures.
Polystyrene. They are practically no different from the previous material, but they have a lower level of strength and therefore break easily due to mechanical stress. Also, polystyrene products cost a little less.
Polyvinyl chloride (PVC). This is the most cheap option material. The low cost has left its mark on the quality: the products are difficult to work with and are prone to dents. To make the outer or inner corner of a PVC ceiling plinth requires a lot of experience and special tool. But manufacturers of these products do not stand still and today you can purchase for these purposes special fittings– corners for ceiling plinths, thanks to which even a novice home craftsman can install plastic parts.
Wooden. These skirting boards look impressive. Unlike all other products, wooden materials installed with self-tapping screws or nails, not with glue.

The above options can be produced in various sizes, have a textured coating or be completely smooth. Usually the color of the products is white, but if desired, you can find or order any other color.

Creating fillet corners

To connect two planks, you can use decorative corners for ceiling plinths. But in the absence of such, the material will have to be processed. Next we will talk about how to correctly cut a corner on a ceiling plinth.

How to use a miter box for processing

A miter box is one of the simplest carpentry tools used to make trimming various products from different angles. It is usually a plastic, metal or wooden tray with several slots in the walls. IN simple version There are slots for 45 and 90 degree angles only. In more complex ones, there are more angles, and professional tool equipped rotating mechanism, which allows you to direct the cutting element at any angle. The principle of operation is simple: before cutting off the corner of the plinth, the workpiece is secured in the tray, and then processed with a cutting tool (knife, saw, etc.), lowering it into the slots.

Trimming ceiling plinth using a miter box

How to properly cut the ceiling plinth for the inner corner on a miter box:

The first step is to attach the plinth to the surface and mark the required length with a pencil.
Then the part is placed in the tray so that its current position coincides with the position on the surface.
Using a clamping mechanism, the plinth is fixed to the far wall of the tool container.
The product is taken with the left hand. Then you need to choose the correct position cutting element(angle 45 degrees). In this case, the handle of the tool should be as close as possible to the left hand.
Applying light pressure on the part, begin trimming. It is important not to press the product too hard, otherwise you may deform it.
The same manipulations, only in mirror image, must be carried out with the second baseboard.

Then the cut strips must be checked for correct processing. To do this, it is enough to connect the ceiling plinth by simply attaching the strips to the surface. If a wooden product is used, it will most likely have to be further processed with a file.

On a note! First of all, it is necessary to design the internal corners on the ceiling plinths, only after that proceed to the external ones. Otherwise, the length of the purchased strips may not be enough.

How to properly cut a ceiling plinth for an outer corner:

Before cutting the corners, you need to attach the fillet to the edge of the wall so that the product extends slightly beyond the boundaries of the surface, and make a mark.
Then perform the same operations as in the previous instructions.
At the end, make a fitting and, if necessary, further process the edges with a stationery knife or file.

Important! To cut the corners of skirting boards using a miter box, you need a perfectly even surface angle of 90 degrees. If there are any unevenness on the walls, due to which there will be deviations of more than 2 degrees, you will have to use other tools.

Processing fillets using markings

Most often, the result of finishing leveling is straight corners. But in some cases, the deviations are so large that even after fitting and filing the fillets, gaps remain. And then the question of how to correctly cut the ceiling plinth using a miter box will be meaningless, since in this situation it is better to cut the planks with preliminary fitting on the spot. To carry out this procedure you will need the following:

A thin hard pencil or marker (such a tool leaves sharp lines, so you don’t have to look closely).
A small fragment of a fillet.
Ruler or tape measure.
Special construction or stationery knife for processing polystyrene, polyurethone or PVC baguettes.
Saw or hacksaw for processing wooden baseboards.

Before cutting the ceiling plinth, you need to lean the strip against the corner and draw a line along the outer edge of the product on the ceiling surface. Then attach the same fillet fragment to the opposite wall and draw the same line.

As a result, there will be an intersection on the ceiling surface, where the cut products will need to be joined. The resulting mark is alternately transferred to the parts that will be joined.

Then you need to take a ruler and connect the edge of the fillet with the markings. After which the product is placed on the table and cut along the line.

This method is quite simple, but it comes with some risks. As a result, the inside of the baseboard can interfere with the connection of the parts on the surface. To prevent this from happening, you can do the following: before cutting the ceiling plinth in the corners, it must be placed on the table in the same position in which it will be glued to the wall. Then cut the outer corner or inner corner at a 45 degree angle. The next plank should be processed in the same way. In this way, lengthy processing after fitting can be avoided.

Next, you need to adjust the joint, but already at the place where the fillet is installed. That is, before gluing the ceiling plinth in the corners, you need to check internal docking without applying adhesive or fasteners. Then carry out the same manipulations for the outer corner planks. After preliminary fitting and bringing the corners to perfect condition, you can glue the products.

Now the question is how to join the ceiling plinths on uneven corners, should not occur.

Trimming with a square

Now let's look at how to cut the ceiling plinth using standard set tools. For this you will need:

ruler or tape measure;
square;
construction, stationery knife or hacksaw.

How can you cut off a corner of a ceiling plinth if the surfaces are perfectly flat:

A ruler is applied to the fillet at an angle of 45 degrees. Using a knife, cut off the unnecessary fragment with one movement of the hand.
In the presence of wooden product, markings are first applied to the plinth with a pencil, and then sawed off with a saw or hacksaw.

If the surfaces of the walls have unevenness, then the first thing you need to do is measure the degree of the angle, and then divide it by two. Let's say the angle is 80 degrees, which means that each product needs to be cut at an angle of 40 degrees.

If adjacent walls do not form a right angle, then to cut the baseboard you will have to make some calculations

Decoration with decorative corners

The easiest way to join ceiling plinths in the corners is to use special products. They are sold in hardware stores and are immediately ready for use. The fillets are simply glued to the surface, and the joint is closed decorative element. In this case, the question of how to properly cut the baseboard does not make sense. Even if the joint turns out to be uneven, this defect will be hidden by a decorative corner.

How to replace a miter box with improvised means

How to make the corners of a ceiling plinth using improvised means? There are several ways:

First way. It is necessary to prepare three wooden boards the same thickness and width. Using nails or self-tapping screws, connect them into a U-shaped structure. Mark the 45 and 90 degree angles (you'll need a square or protractor for this) and then make the cuts using a wood saw. The result will be a homemade miter box. How to trim ceiling skirting boards using this tool is indicated above.

Second way. In this case, before cutting out the ceiling plinth, you should build simple design to hold the fillet. To do this, you need to take two boards and put together a corner from them. Then take paper and draw lines on it going at different angles. Now let's look at how to cut corners using the resulting tool:
- the fillet is laid on a wooden corner;
- in the marked place - a template with drawn lines is applied to the product and trimming is carried out.

Third way. This method is the simplest, but it requires some experience and a steady hand. In this case, you can use any structure that has a right angle, for example, a table.

On a note! Before cutting the corner, measurements should be taken at the fixation site. To mark the inner corner, start measuring from the joint of the walls. Before cutting the outer corner, it is necessary to apply markings taking into account that the product will extend beyond the boundaries of the surface by its thickness.

Installation of skirting boards

This operation will be successful if you follow several recommendations:

Installation ceiling fillets It starts with the design of the corners. After completing this operation, you can begin installing the remaining parts.
When fixing the products, it is necessary to press their edges so that there are no gaps left. In this case, excess glue should be removed immediately so that it does not have time to dry.
If you purchased a PVC skirting board, then to fix it you can use finishing putty, which may have remained after finishing work.
Before gluing the skirting boards to the ceiling, it is necessary to treat the surfaces with a special primer or just water. Then the fillets are put in place and wait until the surface underneath them dries. At the end, the seams and cracks are sealed with sealant or other material with a similar composition. It is better to use sealants containing acrylic.

Installing ceiling plinths is a fairly simple procedure that even a novice master can handle. The main thing is to follow the above recommendations and regularly check the correct installation using a level, even if the fillets look perfectly even by eye. It is also important to remember that this element is purely decorative, so even the smallest mistakes are unacceptable.
