How To Cut A Corner Of A Ceiling Plinth

Preparing corners with a miter box

Builders, carpenters and renovators are familiar with this device.

Miter box. a special wooden tool with slots, in the form of an inverted letter “P”, which allows you to cut a board or plinth so that an angle of 45 or 90 degrees is obtained.

In addition to this device, you will need a clerical knife, a hacksaw for metal and a sandpaper if you work with wooden skirting boards.

The preparation of the corners should be carried out without undue physical effort, so as not to damage the baseboard.

Experienced experts recommend adhering to the following procedure:

  • At the bottom of the miter box, you need to lay the side that will contact the ceiling, and the lower part is pressed against the right wall.
  • The adjacent corner is prepared in the same way, but the plinth is applied to the left wall / slots.
  • The resulting cuts are applied to the corner, if you have a large gap, trim the irregularities with a clerical knife.
  • In the case when a small gap is observed between the prepared skirting board, remove it after fixing all the elements, using putty.

To do this, it is enough to cut the strips at right angles and then insert them into the connecting element. But this solution to the issue cannot always be applied in practice.

Very often the connecting part looks ridiculous, stands out strongly against the general background and spoils the appearance of the room.

The main disadvantage of preparing skirting boards using a miter box is the fact that this method is only suitable for rooms where the angle between the walls is 90 degrees.

Any deviations or irregularities can prevent you from performing this work efficiently. And one more advice from experts.

If you have no experience preparing skirting corners before starting this task, practice trimming or unusable material.

How to cut a ceiling plinth without special tools

If you do not have a miter box and the desire to do it, Using the above recommendations, try to cut the plinth without using a special tool.

To do this, you need to attach the fillet to the ceiling (only the way it will be fixed) and draw the line.

A similar operation is carried out with another wall forming an angle. The intersection of the two lines will show you where to cut off a piece of the ceiling plinth. To do this, you must once again deliver the plank to the ceiling and draw the line from the specified point to the end of the plinth, to the lower corner.

If you need to prepare material for the outside corner, use the following algorithm:

  • On the right side, a plinth is applied to the ceiling and a fishing line is drawn along it.
  • A similar operation is carried out on the left side of the corner.
  • On the plinth, you need to make two marks: the place where the corner of the room passes and the intersection point of your lines.
  • After connecting these points, you will receive the Required cutting line.

Among the main disadvantages of the presented method, it is necessary to highlight the fact that sometimes there are significant errors, the prerequisite of which may be: a human factor, a bad pencil or uneven ceiling / walls.

How to cut a corner on ceiling skirting boards: professional advice

The appearance of the ceiling in your home, apartment or office largely depends on the choice and installation of ceiling plinths. It is not only the color, material, width and other parameters of the presented elements of the decoration of the premises that play a role, but also how they are prepared and assembled.

In order not to make irreparable mistakes in the process of fixing the planks, you need to know the answer to the question: how to cut a corner on the ceiling plinths, and not Turning to professionals for help.

Material for the production of ceiling slats

The first skirting boards were made of plaster. But they did not last long on the building materials market (the main reason is the high cost of gypsum plinths), gave way to products made of polystyrene, wood and expanded polystyrene.

Before proceeding with a detailed analysis of the question of how to properly cut a corner on the ceiling plinths, it is necessary to find out what are the features of each category of the presented products.

Polyfoam is the most economically profitable material for the manufacture of ceiling plinths. The main advantages of this product category are:

  • Low cost;
  • Looks great on the ceiling;
  • It is not difficult to choose skirting boards that harmoniously fit into the interior of almost any room;
  • Well cut;
  • Easy to work with this skirting board.

There is also a “reverse side of the coin”. Foam products break easily, but many experienced experts say that this fact is not a serious problem (the skirting board is NOT physically affected on the ceiling).

Even if you do not know how to properly cut the corners of the ceiling plinth, you can practice on products from the presented category (cut pieces, etc.).

Expanded polystyrene, which is used as a material for the production of ceiling skirting boards, is stronger than polystyrene, but this criterion negatively affects the cost of products.

The main advantages of the presented category of skirting boards are their high strength, long service life and the ability, without strong physical efforts, to cut off the corners you need.

Wood products are more expensive and look more solid than the above products. But the presented category of ceiling plinths is difficult to machine.

In order to cut off a corner, you will not only have to work with a hacksaw (experienced experts recommend using a blade for metal), but also eliminate irregularities using a sandpaper.

The question of cutting the corners of the ceiling plinth must be solved taking into account the materials that are used for their production. For example, for the preparation of foam products, you can use an ordinary stationery knife, which will be a poor helper if you are installing wooden skirting boards.

Skirting board

After studying the information provided, you can answer the question of how to cut a ceiling plinth using different methods of solving this problem. But besides this, you need to know effective ways to connect the strips.

One of the ways (in which it was already mentioned) is BASED on the use of connecting elements.

They are available for external corners, for internal corners, as well as for joining skirting boards in straight sections. A very convenient way to save time, and in some cases, financial resources.

Even experienced professionals will NOT be able to mount skirting boards for ceilings so that everything is perfectly smooth and beautiful.

In order for the quality of the work performed to be at the highest level, you must use the following recommendations:

  • On straight sections of the plinth, you need to connect so that one part slightly covers the other;
  • After applying glue at the joints, the remains must be wiped off;
  • All gaps between different parts or between the skirting board and the ceiling / walls must be sealed with a sealant (alternatively, putty with water-based paint).

How to make a miter box without the help of specialists

If you do not have a miter box, but you know that you can use it to prepare ideal angles, then make this device yourself.

For this you will need:

  • Three small boards;
  • Nails;
  • A hammer;
  • Hacksaw for metal.

You make a small U-shaped tray with cuts, which form the corners necessary for your task. The main thing is not to rush, carefully check your cuts (preferably with a protractor) and make sure that your structure is stable.

If you know how to cut a corner of a ceiling plinth, but for this you need a device that allows you to cut off non-standard corners on fillets (another name for plinths), make the necessary tool with your own hands.

To do this, you need to connect two rectangular boards with the letter “G”, and make cuts on one of them. On paper, using a protractor, you need to draw a mowing line so that they form the desired angles from one of the boards. The device is ready, it remains only to test its functionality in practice.

As a last resort, you can always find some kind of thing that will help you cut off part of the baseboard at the right angle (book, table pushed against the wall, etc.).

An important point! Taking measurements, Considering that for the outer corner of the ceiling plinth, you need to take a margin equal to its width (fillets, in this case, protrude outward).

A few tips from experts

If you are interested in the question of how to cut corners on ceiling plinths, from a theoretical point of view, or you plan to make repairs in the indefinite future, then you should remember some tips:

  • Making repairs indoors, make sure that all the elements Not only create an overall beautiful picture, but also “dock” with each other;
  • You should NOT buy wooden skirting boards if you DO NOT know how to work with it;
  • We fix the planks only after they are fully prepared (you are unlikely to succeed in cleaning the unevenness on the glued ceiling plinths)
  • Installation of ceiling strips should be carried out, starting from the corners, according to the principle: “from complex to simple”;
  • When buying ceiling skirting boards, take the material with a margin (not only taking into account possible errors, but also to compensate for losses on uneven walls).

Practice shows that trimming the ceiling plinth, despite the complexity of this process from the position of beginners, after “passing” several corners, is perceived much easier. But doing similar work in a room with rounded corners can be a serious problem even for professionals.

Typically, such problems are solved using a method that is BASED on creating “patches” where the bottom is wider than the top. This work requires perseverance, a good eye and accuracy.

After a detailed study of the question of how to cut the ceiling plinth in the corners, even a person without experience in this field of activity will be able to independently perform this task at home.

As a result, you will not only save money, but also get moral satisfaction after the repair work.

How to cut a corner of a ceiling plinth

In this article we will talk about how to properly cut the outer and inner corner of the ceiling plinth with your own hands. This can be done without the use of Special tools, but it should be understood that such work requires care and accuracy.

Which skirting board is better to choose?

There are many varieties of fillets, which differ in the following characteristics: material of manufacture, shape, and dimensions. When choosing a ceiling plinth, it is recommended to focus on all these factors, but the material of manufacture is the key point that determines the complexity of processing.

The highest quality polyurethane fillets are considered. However, they are the least suitable for cutting corners, since the material is highly elastic. The easiest way to cut the inner or outer corner of a polyurethane skirting board is to use a miter box. The main disadvantage of such products is their poor resistance to high temperatures, therefore they are prohibited from using in the kitchen.

Fillets

Products made from second materials also have their drawbacks. Ceiling skirting boards made of PVC are prone to dents. In turn, polystyrene foam products break easily, so they must be handled very carefully.

So which skirting board should you choose? There is no definite answer to this question. Experts recommend focusing on the individual characteristics of the premises and the budget calculated in advance.

Miter box cutting: inner corner

The easiest way to get the correct inner corner is to use a professional tool. Of course, such work can be done without a miter box, however, but in this case, more effort will be required. Consider the sequence of actions for cutting an inner corner using a miter box.

The first thing to do is determine the distance from the outside corner to the nearest wall. Further, you will need to mark the plinth, having prepared it for cutting. On the outside of the fillet, you need to draw a fishing line along the length of the measurement. It is worth considering that in this case, the upper part of the die should protrude slightly outward.

Then you can start trimming. For this, the skirting board is placed in the cutting tool and pressed securely against the wall. After cutting the first part, you can start processing the counter element.

Miter box cutting: outside corner

Most often, when installing ceiling plinths, home craftsmen are interested in how to properly arrange the interior corners in the room. Cutting outside corners is done less often, but with a certain layout of the walls and it is necessary. Consider how to correctly make the inner fillet using a special tool (miter box).

First you need to purchase a miter box. This tool is a tray in which the part is fixed and trimmed. In order to measure the length of the required product, you need to attach it to the ceiling. Next, you need to install the plinth in the miter box. Its location should correspond to the position it will occupy on the ceiling.

Miter box

How to properly cut the inner corner of the ceiling plinth is a difficult question, the corresponding photos help to answer. Experts recommend studying them, and only after that start work.

After making sure that the product is positioned correctly in the tool, you can start cutting itself. The hacksaw must have a certain angle, namely 45 degrees. During operation, it is not recommended to exert strong pressure on the cutting tool, as the surface can be damaged by the miter box. Then the adjacent fillet is trimmed, which is done in a “mirror” way.

Cutting corners without miter box

Not everyone has the opportunity to purchase a professional cutting tool. And the expediency of such a purchase is rarely justified, since it spends money on a miter box that will be used only once is not the best solution. You can trim fillets without it. There are several alternative ways to get the right angles.

Manual template preparation

The first and most common option for trimming fillets without using a miter box takes into account the use of a paper stencil. To implement this method, you will need to prepare the following tools and materials:

  • Protractor;
  • Pencil;
  • Cardboard.

We apply a plinth to the cardboard blank and cut it off with a hacksaw. Some craftsmen perform markings on the product itself. In this case, there is a need to use the template.

The second option is to make your own cutting tool. To do this, you need to prepare 3 boards, which have the same dimensions (50 by 15 cm). Next, you need to dock them together. The two side boards, which are the walls, must be fixed to the cross board at right angles. In the next step, you need to mark an angle of 45 degrees on the walls. You can take the necessary measurements using a simple square. The finished tool will allow you to arrange all the corners in the room in a short period of time.

The third method takes into account the use of improvised means. In this case, there is a need to design a template. It can be replaced by an ordinary table, which will need to be moved to the wall. It is necessary to attach a fillet to the corner formed in this way, and then mark it. At the end, the part is cut with a hacksaw or a construction knife.

Indirect corner cutting

Walls do not always have a perfectly flat surface. In this case, it is very difficult to carry out the installation of ceiling plinths, since few people know what exactly needs to be done in such a situation. The most preferable solution to cope with this problem is to mark the corner in place.

For marking, you need to prepare a regular pencil. Before starting work, it is recommended that you familiarize yourself with. Which describes the nuances of trimming fillets. The first step is to attach the plinth to two walls (in turn). Along its edge it is necessary to draw a fishing line, which is marked on the ceiling. The point that corresponds to the intersection of the lines is marked with a pencil.

In the horse, you need to connect a point to the bottom edge of the fillet. Next, trimming is done. It is recommended to use a ruler during work. If the work was done correctly, then the resulting angle repeat the wall relief.

In order to cut the correct corner of the ceiling plinth with your own hands, it is not necessary to use a professional tool. There are other methods that do NOT require anything complicated from the master. In such work, the most important point is the correct markup. Before you start cutting, be sure to make sure that you are doing everything correctly.

What advice can you give for cutting the corners of ceiling plinths?

Method two. no additional tools

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

  • Attach the fillet to the ceiling, tightly presses its even edge into the corner.
  • Draw a line along the long side of the baseboard on the ceiling.

Do the same with the adjacent part on the other side.

Mark the point of intersection of the lines.

In total, you get an even angle of 45 degrees if you draw the line from the point of intersection to the edge of the part. This method of how to cut a skirting board is available to everyone, without the presence of Special tools.

The first way is with a miter box

Professional miter box with a swivel hacksaw Long ago carpenters invented such a special box with slots. a miter box. It is easy to recognize it, among the variety of repair equipment, by its characteristic appearance. This is the most convenient and indispensable device in solving the problem that has arisen, how to cut the corners of the ceiling plinth.

The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool is the oldest and simplest carpenter’s tool for cutting wood pieces at 90 and 45 degrees. There are types of such a device for professional work, with a swivel mechanism, in which the cutting tool can be rotated and fixed in any position.
How to cut a ceiling plinth correctly
Ceiling corners can be divided into internal and external, the method of joining them is slightly different.

If necessary, you can make a miter box with your own hands. To do this, you can use 3 scraps from plywood or boards of the same size. First, for this you need to attach them in the form of an inverted letter “P”, and make a marking of the corners. Then, along the markings, they are cut out with slots for a hacksaw almost to the very bottom, and the boards are twisted.

Outer corner

  • Measure the length of the skirting board from the nearest wall to the outer corner, leave the line on the wrong side with a pencil, indicating the desired length. Keep in mind that the edge (its upper part) should extend slightly outward.
  • Move the skirting board to the miter box and cut it.
  • The adjacent bar also needs to be measured with a margin, and cut off in a mirror image to the first part.

Trying on the ceiling plinth. the joining of the parts should be perfectly flat. If the result is not achieved, and there is a protrusion at the joint, you can trim the edges with an ordinary knife to a perfect joint.
Checking the smooth docking
In this article, all the nuances are well described:

Cutting the ceiling plinth with your own hands

We will analyze in stages how to correctly cut the corners of the plinth (also called fillet).
In the vast majority of modern apartments, the corners of rooms and other rooms are 90 °. Cut the ceiling plinth at an angle of 45 ° or 90 °.
How to cut a ceiling plinth? For this, a special tool is used, which is called a miter box.
This tool has already been slotted at an angle of 45 ° and 90 °. A seemingly simple task to cut the skirting board.
But the fact is that it is glued to the ceiling at an angle of 38 ° to 45 °, which means that the cut corners should not be joined, leaving gaps. To prevent this from happening, they use a miter box.

It looks like a miter box

Trimming the skirting board for the inner corner

If you do not have a miter box, then you can do without it:

  • To do this, we apply the plinth to the ceiling as it should stand, and draw a line along the ceiling.
  • Then we put the plinth to the ceiling, the case of the corner and draw the second line.
  • In the place where the mowing lines intersect, make a mark on the plinth and draw the line from the mark to the bottom corner of the plinth. This line will be the trim line of the skirting board.

Marking for trimming the left corner of the skirting board

Proceed in the same way with the left corner. Cutting strictly along the line with a sharp knife.
Then we apply it to the corner and check if there are gaps. If there is a gap, then carefully trimming the corners.
Then the skirting board can be glued in place.

Council. DO NOT use excessive force when trimming the skirting board. It may wrinkle and after you stick it in place after the glue dries, deform.

Marking for trimming the right corner of the skirting board without miter box

Undercutting the right corner of the skirting board

How to cut ceiling plinth and floor

The most difficult part when installing ceiling and floor skirting boards is the corner design. It is necessary to dock the planks in such places very carefully, otherwise the appearance of the decor will be hopelessly spoiled. Of course, you can use quite aesthetic special corner pieces.

However, naturally docked planks usually look more harmonious. And in this case you will NOT have to spend on additional details. Therefore, later in the article, we will consider how to cut the corner of the ceiling plinth correctly and how to process the seam.

How to cut a ceiling plinth correctly

This is how the corners of the ceiling plinth look correctly cut

You can make such an ideal ceiling plinth with your own hands if you follow these instructions.

For the manufacture of ceiling cornices, three materials are mainly used, these are:

They also make stucco ceiling cornices, but this is a different topic.

  • The weakest and cheapest of them is polystyrene, although strength on the ceiling is not very required.
  • Expanded polystyrene is much denser than it can be easily cut with a knife and, of course, it is more expensive.
  • Wood is the hardest to handle. In order for the corners of the wooden skirting boards to be ideal, you must use an exclusively fine-toothed hacksaw, and even better a hacksaw for metal and a sandpaper. Only in this case can you achieve an even angle.

Other methods

With a good eye and accuracy of hand action, you can use a homemade template that resembles an imitation of a miter box. To do this, take a thin board or thick plywood, and draw the layout in the form of a horizontal rectangle. Use a protractor to mark 45 degrees on the right and left sides of the rectangle. Draw the mowing line connecting the opposite edges. Now you can solve the problem of how to cut the ceiling plinth with this layout. The actions are simple and similar to the description above in the first option. Only the ceiling parts should NOT be inserted, but put on the drawing and combine the hacksaw with the layout of the layout.

How to cut a skirting board without a miter box

How to make a corner of a ceiling plinth without a miter box

Few people in apartments or houses have angles of exactly 90 °. Small deviations are easily corrected after fitting. But not always. Then you have to mark everything “in place”. under the ceiling.

You will need a finely contoured pencil (hard. it is not so visible on the ceiling, but leaves quite clear marks near it), a small piece of plinth, a ruler and a good stationery knife if you work with polyurethane (polystyrene) baguettes or metal dust to work with other materials.

Apply the plinth to the corner, draw along the outer edge with a pencil. Apply to the other side of the corner, also mark. You have a cross on the ceiling, the center of which marks the place where the plinths of the ceiling plinth should converge (look at the photo). I installed a piece of plinth in the corner, which will stick there and resting it with its end on the wall, transfer the mark to it.

How to make corners on skirting boards without using special tools

Now take a ruler and connect the edge of the skirting board with the marked mark. If you just put the plinth on the table and cut along the mowing line, the two parts in the corner will still NOT fold: the inner part will interfere. You can trim it later, try it on the ceiling. The second way is to install a piece that needs to be cut on the table, then a piece that will be on the ceiling. And cut along the mowing line, but keeping the knife at an angle of about 45 °. It will still be necessary to correct, but much less (and less chance of error).

Repeat the same operation with the second bar. Attached to the desired wall, abuts the butt against the adjacent wall, mark the place where the cross is drawn, draw the line and then Cut it off. Correction Carried out “dry” without applying glue.

You repeat exactly the same steps for the outer (protruding) corner. Now you know one more way of how to make a corner of a ceiling plinth, and without a scissor or other special devices.

With decorative corners

There is one more, simpler way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory decorative corners. They are installed in a corner, strips are glued to them closely. Cutting them if necessary is very simple: a few millimeters with an ordinary clerical knife.

Examples of finished corners for fillets

How to cut ceiling plinth in corners

The quality of the ceiling finish greatly affects the appearance of the room. Then they try to do everything perfectly, or very close to it. The finishing touch to the design is the ceiling plinth. They give the finish a complete and holistic look. The strips themselves are mounted on flat surfaces simply: on special white glue, but problems arise with the design of the corners. Without knowing how to make the corner of the skirting board correctly, a lot of material deteriorates. How and what to cut it in the corners and tell you.

With the introduction of miter box

If the corners and walls in the room are even, you can use a special carpentry tool. a miter box. This is an inverted U-shaped chute in which the mowing line is marked for cutting at 90 ° and 45 °. The part in which you need to make a gash is laid inside, a saw is inserted into the guides. The part is held in place, cut to the desired angle.

This is what the miter box looks like. Can be plastic, wood or metal

In the case of a skirting board, not everything is so simple: they must simultaneously lie on two surfaces, therefore they need to be pressed against one or the other wall of the miter box. When working from the ceiling, they are pressed against the side closest to you.

The sequence of actions when finishing the outer corner, you need to make a gash at an angle of 45 degrees. Place the miter box in front of you. I try on how the plinth will be located, determining which part of it will be attached to the ceiling. In order not to get confused and cut off the ceiling plinth correctly, the bar that will be located on the right, We put the case, then that on the left is on the left.

How to cut a corner on ceiling skirting boards: correctly Install it in a miter box

The part that turns out to be on the ceiling presses against the lower part with a miter box. The other side is closer to you and raised. She is supported on the wall of the device so that she does not stagger when cutting. That is, the front of the skirting board turns out to be turned away from you. Do the cutting direction as shown in the photo below. By folding the two cut pieces together, you get a Protruding. Outside or Outside Corner.

How to Make the Outside Corner of a Skirting Board Using a Chair

First put the cut-off parts in place “dry”, without applying glue. If the geometry of the corner turned out to be not ideal for centuries, you can touch up a little with a knife. It is easier to cover small errors with a special putty.

The situation is very similar with the inner corner of the skirting board. First you try on which side will be on the ceiling, this part is pressed to the bottom with a miter box, the second part is supported on the wall closest to you and cuts as shown in the photo below.

How to make an inner corner of a ceiling plinth with the introduction of a miter box

And again, at first I try it on without applying glue, if necessary, I slightly correct it. Then apply a thin bead of glue to both surfaces that will stick to the wall or ceiling.

Your own version of how to use the miter box correctly is shown in.

What is it made of and what is it called

The very first skirting boards on the ceiling were made of plaster. They were cast in special molds, then installed in a solution on the ceiling. Such figured decorations were called fillets. Today you can see them rarely are expensive, and outwardly they almost do not differ from the cheaper options. And the name is almost lost.

The most popular ceiling skirting boards are made of polyurethane or polystyrene. They are inexpensive, look great, are easy to install, have a wide range of profiles and patterns. The width can be from 5 mm to 250 mm. They are used in almost any room, decorated in any style. The exception is wooden houses with a corresponding interior. Wooden products are most often used here. the style dictates its conditions.

There is also a similar plastic finish. It is mainly installed in bathrooms. But even in damp rooms, you can safely mount polyurethane strips. they are NOT afraid of damp.

You need to cut the ceiling plinth in the corners of any material in one of the ways described below. The only exception is plastic skirting boards: such a corner can be issued only with the introduction of ready-made corners.

What and how to cut

Working with skirting boards made from different materials means using different cutting tools. When working with a wooden skirting board, it is more convenient to work with a saw on wood. All others, including plastic, made of foam and other polymers, are better cut with a metal sheet. The result is a smoother cut, less burr. Saws are usually used when working with a miter box.

Corner design looks attractive

When working with a polystyrene skirting board without special tools, they cut them with a good office knife. Its blade is quite thin and even, the cut is smooth, wrinkled. If you use a saw with hydro- or polystyrene, do not press hard: you can wrinkle.

In general, in order to get used to the tool and material a little, take some piece and practice on it: cut, saw, trim. So there will be fewer problems when working.

How to get the correct angle

Most of the problems when working with skirting boards arise when making corners. Since the surface in the products is complex, it will NOT work simply to cut at the desired angle: it is also necessary to cut it so that they dock and, preferably, without large gaps. In reality, there are several ways to make the corner of the skirting board Perfect (or almost).

How to join in corners

If the installation of the first corner is completed, we can assume that you have already learned almost everything. “Almost”, because you still need to learn how to join the corners and cut the planks to length. When some part is already glued and a small distance is left to the corner, how not to be mistaken with the length? The answer is simple: leave stock.

At first, you can cut a piece 10-15 cm longer: it will be possible to redo it several times if something does not work out right away. Then you make the corner in the way described above, try it on dry, adjust everything so that the result suits you. Only then can the already cut bar be attached to the corner and mark the place where it can be shortened. You need to trim at exactly 90 °. It is not necessary to use a miter box. Just try to put the knife (hacksaw) perpendicular to the surface.
