How To Properly Saw Down The Corner Of The Ceiling Plinth

How to make an inner corner

How To Properly Saw Down The Corner Of The Ceiling Plinth

  • Press the fillet to the inner corner in the way it will be glued.
  • With a pencil, draw the fishing line along the upper edge of the part (on the ceiling) towards the corner. Next, take the second one and press it in the same way to the second side of the wall.
  • Draw the line with a pencil in the same direction towards the corner. As a result, you get the intersection of two lines on the ceiling.
  • Then, reattach the skirting board on one side in the same way and mark the intersection of the lines on it. Do the same with the second baguette.

As a result, if you run the line from the mark to the bottom edge of the fillet, you get a straight line at an angle of 45 degrees.
To correctly cut the inner corner of the ceiling molding, follow these steps:

  • Transfer the workpiece to the device in the same position as it will be attached to the surface and press it very tightly against the back of the tool.
  • Put the hacksaw in the slots at 45 degrees to the workpiece, which must be held by hand during work, so that it does not shift.
  • Carefully cut the baguette, controlling the pressure of the tool, so as not to damage anything.
  • Another piece of the skirting board should also be placed against the back of the device, also pressing and holding it tightly during operation, avoiding displacement.
  • Set the hacksaw at 45 degrees to the workpiece so that it is opposite the first trimmed border.
  • Cut off. Done!

It is imperative to cut off the plinth from the front side of the product so that the line turns out to be even and clear.

How to cut a baguette in the corner of a wall using a machine

A miter box is a U-shaped tray with sides in which slots are made for the cutting tool. There may be three or more slots, depending on its purpose. The slots are made in such a way as to cut parts from 15 to 135 degrees. In this case, I am interested in a simple tool with a minimum set of slots for cutting at angles of 45-90 degrees.

The tray provides a ready-made template for cutting at different angles. It can be used to trim both internal and external protrusions. In its absence, you can make it yourself. This will require four planks, even and preferably smooth. Knock the tray out of them and proceed to the holes for cutting. Mark them at 45-90 degrees, cut with a thick cutting object or circular saw.

  • The ceiling plinth is applied and cut on the near inner side of the tray.
  • The baguette is installed in the same way as it is planned for fixing to the ceiling.
  • Cutting the workpiece should only be at 90 degrees.
  • The side that will be glued to the ceiling should be firmly pressed against the bottom of the tray during operation.
  • The border is cut here strictly on the front side.
  • For each material from which the skirting board is made, you need to choose the right cutting tool.
  • It is best to start cutting fillets from the inner corner, otherwise the part may turn out to be shorter and not fill the entire length of the ceiling.

How to make an outer corner

Just as the mowing lines were outlined for cutting the inner corners, the outer corners must be done. Attach the planks to the wall at the protruding corner. On the ceiling, mark a line along the length of one baguette, then line along the other. You will get the intersection point, which should be marked on the upper parts of the skirting board. Draw a line from it to the lower edge of the workpiece (make two sides in this way).

Then work with the marked lines of the outer corner of the baguette as follows:

  • Place the workpiece in the tray, pressing firmly against the front wall of the device and holding it with your hand during operation.
  • Set the cutting tool at 45 degrees to the workpiece and carefully cut off the corner.
  • Install the counter plinth in the same way, pressing it against the front wall of the device.
  • Cut at 45 degrees, but in such a way that the angle is directly opposite to the already cut.

After all the corners are cut off, it is required to dock the fillets together, checking for defects in the work. If there are any, remove them by carefully cutting with a knife. As for wooden curbs, the unevenness on them must be removed with a file.

Skirting Corner Tools

Initially, you should decide what exactly to cut. If it is a lightweight material. polystyrene, such as polyurethane, etc., then a clerical or well-sharpened knife will do. But the most versatile tool for cutting curbs from any material is a metal hacksaw. She cuts almost everything, smoothly and quickly.

A ruler and a chalk or pencil will also come in handy, and when manually cutting a plinth, an angular ruler is required.

How to cut corners on a skirting board

The ceiling plinth gives an aesthetic appearance to the room after renovation. It hides all minor construction defects, gaps and crevices. Since it runs along the entire perimeter of the room, you need to be able to dock it at the corners. This is not difficult and is done in several simple ways.

How to cut the correct corner of the ceiling plinth with your own hands

You only need to cut corners on baguettes at an angle of forty-five degrees, which will help to combine both the outer and inner parts of the material. This can be done either through a slotted tray or in its absence by applying the necessary markings on the ceiling or on paper.

To join the fillets with a decorative corner, you need to place the corner exactly in the center between the walls to the ceiling. Attach to it on both sides of the plinth and cut them a little with a clerical knife until they fit perfectly together.

The problem is that the standard sizes of such corners do not always fit the size of the curb, in which case it is better to cut the corner yourself.

Preparatory work

Before starting work, you should prepare the material with which you will have to work. Fillets are made of:

  • Wood;
  • Gypsum;
  • Styrofoam;
  • Polyurethane;
  • Pvc.

Based on this, you need to prepare the tools. Depending on the material, a device is selected that will easily cut off the part. Also, there should be glue for attaching the skirting board and a sealant to mask minor defects.

There is also special fittings for decorating corners. they are attached to the joints at the corners. Its benefit is that it can hide some irregularities in work.

How to trim corners on curbs without a machine

The device for trimming ceiling corners is suitable provided that the walls are flat, which are located perpendicular to each other and to the ceiling. Otherwise, this unit will not help in any way and the angles will have to be adjusted manually. How to do it?

In the same way as described above, mark the cutting line by cutting the skirting board against the ceiling. Then, carefully cut them off on a flat surface with a hacksaw, as far as possible, butting them to the desired ledge and trimming the flaws. Careful fit will help you cut corners most clearly.

You can draw a diagram of the angle on paper (if it is perfectly straight), using a square, measure the cutting line of the cut along it and cut them evenly along it.

You can also measure the width of the fillet, use a ruler to set aside this value at the bottom of the plank and connect the protruding corner with the marked point with a straight line. Do the same on both opposite planks.

Then dock and see the result: if there are no gaps and everything is cut out clearly, you can glue it. If there are any flaws, the seam turns out to be imperfect. you need to adjust it with a sharp knife, cutting off the excess.

If you use these simple rules and pay attention to the tips, then you can independently, without the help of specialists, figure out how to correctly cut a corner on the ceiling plinth. It won’t work the first time, you need to practice on short details first. Since there is nothing to hide flaws on the ceiling, how can you do this on the floor, you need to cut it out carefully, often trying on the product to the place of further gluing.

The ceiling plinth completes the completeness of the picture of the room after renovation, gives it neatness and should harmoniously fit into the design of the future room.

How to cut a corner on a skirting board: 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 to prevent irreparable mistakes in the process of fastening the planks, you need to know the answer to the question: how to cut a corner on a ceiling plinth without asking for professional help.

Skirting board

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

One of the ways (which has already been 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 specialists 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, the plinth must be connected so that one part slightly covers the other;
  • After applying the glue at the joints, the residues must be wiped off;
  • All gaps between different parts or between skirting boards and 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.

Make a small U-shaped tray with cuts that form the corners necessary for your task. The main thing is not to rush, carefully check your incisions (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 necessary angles with 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! When making measurements, keep in mind 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).

Material for the production of ceiling slats

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

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

Polyfoam is the most economically advantageous 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;
  • Cut well;
  • These skirting boards are easy to work with.

There is also a “reverse side of the coin”. Styrofoam 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 with products from the category presented (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 resolved taking into account the materials used for their production. For example, to prepare foam products, you can use a regular stationery knife, which will be a poor helper if you are installing wooden baseboards.

Preparing corners with a miter box

Builders, carpenters and renovators are familiar with this device.

A miter box is a special wooden tool with slots, in the form of an inverted “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 are working 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 / slot.
  • 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 boards, remove it after fixing all the elements using a 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 are inexperienced in preparing skirting corners, practice on trim or unusable material before proceeding with this task.

How to cut a ceiling plinth without special tools

If you do not have a miter box and the desire to make 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 attach the plank to the ceiling and draw the line from the indicated point to the end of the plinth, to the bottom corner.

If you need to prepare the material for the outer 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 point of intersection of your lines.
  • After connecting these points, you will receive the necessary cutting line.

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

A few tips from experts

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

  • When 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;
  • Fix the planks only after they are fully prepared (you are unlikely to be able to clean up irregularities on the glued ceiling plinth);
  • Installation of ceiling strips should be carried out, starting from the corners, according to the principle: “from complex to simple”;
  • When buying ceiling plinths, 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 major challenge, even for professionals.

Usually such problems are solved using a method that is based on the creation of “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 join skirting boards in the corners

When a certain part of the skirting board is glued and a small distance remains to the corner, so as not to be mistaken with the length, it is necessary to leave a margin.

To begin with, you can cut off a piece that will be 10-15 cm longer. Then cut the corner in a convenient way, try it on a dry surface, attach the plank to the ceiling and highlight the place to which it needs to be shortened. Cutting is performed at an angle of 90 °.

Next, you need to correctly join the corners. The made ceiling moldings are attached at an angle of 38-45 °, so the classic 45 ° is not always suitable at the joints.

In various cases, the cut edges do not join and leave gaps. For this reason, after the initial trimming of the corners, it is necessary to carry out “dry” and the most accurate joining of the baguettes directly to the ceiling. Especially you have to tinker with wood and plastic materials.

How to glue a ceiling plinth

Start from the corners of the room, as they are easier to work with, then move on to other parts of the room. Cover the corners in such a way that, if possible, no gaps are formed or defects, if they are inevitable, are minor. For plastic skirting boards, use a finishing putty.

Water or soil is applied to the areas for fasteners.

After the putty mixture has dried, all the cracks need to be repaired. various sealants are used for sealing (professional builders recommend choosing acrylic-based products). In general, one package is required per room. Installation with a sealant is carried out in the same way as when using a putty.

Making corners using a miter box

If the walls and corners of the room are even, you can use a miter box for work. In order to cut the corner correctly, a part should be laid inside the miter box, in which the person will make a gash, then insert the saw into the guides.

This holds the part in place and can be cut at the desired angle. For high-quality cutting of the skirting board, it must simultaneously adhere to both surfaces, therefore it should be pressed against the wall of the miter box. The ceiling plinth is pressed with the side that is closer to you.

With a miter box, you will need to cut a 45 degree angle. First you need to decide how to position the plinth in the miter box. To avoid confusion and cut correctly, place the right plank on the right and the left plank on the left.

Follow the instructions below:

  • Press the part of the miter box that will be on the ceiling to the bottom of the miter box. The other side will be lifted up and closer to you. It can be resting on the wall of the tool, and then it will not stagger when cutting.
  • Determine the cutting direction as shown in this illustration, and then cut the corner.
  • Fold the cut pieces together. you have an inside or outside corner.

Place it on the ceiling and check the geometry. If it is not even enough, it can be slightly corrected with a knife, and in the case of minor defects and wide gaps, you can use a putty.

How to make an even corner: ways

The most difficult thing is to cut the corner so as to get a perfectly even one: the surface of the materials used is not easy to cut, in addition, you need to observe good joining, preferably without huge gaps. How to make a corner on a skirting board? You can use several ways: with a miter box, without a miter box, using decorative corners, as well as an alternative way.

Using fillets

You can not make fillets yourself, but immediately purchase those that were initially prepared for docking. This is how they produce polystyrene fillets, which do not need to be adjusted to each other.

The baguette that will be fixed to the left must have a right cut, and the right baguette must have a left cut. When creating the inner corner, make the bottom section rise above the top, for the outer corner everything should be the other way around.

Attach the baguettes to each other, if necessary, make undercuts at the joints of the base. If everything is in order, the skirting boards can be fixed with glue or screwed to the walls with further sealing of the seams.

Outside corners are less common than inside corners, and cutting is much easier. Now we will do everything the other way around than when we cut the inner.

Initially, we need to mark where our corner will begin, and for this we apply the ceiling plinth to the wall with markings: now the point of intersection of the ceiling plinths will be the upper point of their abutment, mark it with a simple pencil and we can start the preparation of the plinth: to prepare the left-sided one, we place the plinth in miter box in such a way that the top of the baguette is pressed against the wall, the bottom. against the bottom, and the long edge is on the right. Cut off again along the slot with a mark of 45 degrees. The right-side corner is harvested according to the same principle, only the long edge of the canvas will be on the left.

In the case of rounded corners, no devices will help us and we will have to do everything “by eye”.

The easiest way to make such an angle is: the ceiling plinth is cut into several pieces of about 5 cm each, we cut all parts on both sides and check the joint in place, correct it, if necessary, and glue it one by one. Leave the pieces that will join the main plinth at the beginning and end of the rounding, on one side, leave even. It is important not to confuse the fragments, so you can number them with a simple pencil.

  • Do not be afraid that gaps may remain at the joints on the ceiling plinth, because they are easily putty and become invisible after drying and staining. Exceptions are wood skirting boards. even matching putty can be noticeable.
  • Try on the cuts while still on the floor, as this is easier than using a ladder. Do not glue the skirting boards until you are sure that everything is cut correctly.
  • Do not be discouraged that something does not work out, and the cuts have to be adjusted several times, be patient and everything will work out.

As they say, the eyes are afraid, but the hands are doing! If you think over every movement well, there is nothing wrong with trimming the plinth yourself, and a beautifully decorated room will delight the eye of the owner and his guests.

A high-quality renovation requires an attentive and accurate attitude to details.

Finishing the work with the ceiling, you need to arrange it well. for this, ceiling plinths are used. As a rule, the installation of slats does not cause any particular difficulties; you will have to tinker with the corners. Let’s take a closer look at how to cut the ceiling plinth in the corners, talk about different methods, and give useful recommendations on the topic.

Ceiling skirting boards from any material can be cut using one of the methods described below. They are suitable for everyone except for plastic ones: they are made out using ready-made corners.

Important points

Let’s consider how to correctly cut the corners of the ceiling plinth and get an excellent result the first time. Follow a few helpful tips:

  • Before fastening, both parts must be matched to each other. Attach both halves to each other. The surface of the wall must be dry. Finding defects, you can easily level them with a knife.
  • Several trims may be required. Don’t be discouraged if it takes a long time and has to make a few trims, especially if this is your first time doing the job.
  • Determine the correct length of the planks in the corners. For the inner corner, the length of the plank should be adjusted exactly from corner to corner; on the outer corner, the measurement is taken from the inner point towards the room.
  • If the corners generally match perfectly, but there are small gaps in the middle, they can be repaired with a putty.

Cut to an inner corner

We cut the skirting board under the inner corner.

Most often, the room has internal corners. If you use our advice, then this work will not seem very difficult.

Step-by-step instructions for pruning with a miter box.

  • We apply the bar to the ceiling and measure the required length.
  • We install the plinth into the fixture so that its location coincides with the position on the ceiling.
  • To perform left-side cutting, the plinth is placed “upside down“, that is, the part adjacent to the ceiling in the fixture is located at the bottom, and the one adjacent to the wall is at the top of the tool. Trim at 45 degree slot.
  • Right-side cut: the blade is set so that the longest part is on the right.

If the miter box was not at hand, then the markings are made on the table. For this, two parallel mowing lines are carried out (the distance between them is 20 cm). Then draw another, which connects the first two at right angles, and two more mowing lines, intersecting with the connection line at an angle of 45 degrees.

All three outlines intersect in the middle. The result is a painted miter box. A canvas is applied to it and cut off according to the principle described above.

Step-by-step instructions using markup.

  • We apply the plinth to the ceiling and line the inner edge of it.
  • The same manipulation is performed on the other side.
  • We apply the canvases one by one and mark at each point where the inner edges of the plinth intersect.
  • Draw a line between the opposite edge and the marked point.
  • We carry out the cut correctly.

Fitting and joining corners is considered the most difficult work when installing a ceiling plinth. For a beginner, this is a troublesome business, a lot of materials are spoiled for trial and error, which may never lead to anything. And to the question of how exactly to properly cut the corner on the ceiling plinth, we will try to answer.

Use a utility knife to cut the Styrofoam ceiling plinth.

In fact, there are not so many ways:

  • You can cut a corner with a miter box;
  • And you can cut the plinth using markings.

Based on the methods, we need the following tools and materials:

  • Miter box;
  • Ruler;
  • Pencil;
  • Stationery knife or saw for metal;
  • Skirting board.

In most cases it is indispensable as it reduces the chance of pruning errors and is a great time saver. It is not expensive, but it will provide you with correctly fitted joints, and in the end. a beautifully decorated room.

We will need a clerical knife or a metal saw if the corners of the room are uneven, which happens quite often. Then the markup method will come to our aid.

Cutting scheme of the ceiling plinth in the outer and inner corners.

Most often, we are faced with the need to cut the inner corners of the ceiling plinth, and they constitute a particular difficulty. But there are a couple of secrets that will help us deal with this properly. So, if we use a miter box, then we need to put the canvas in it in such a way that its bottom is pressed against the wall a little further than the right slot with a mark of 45 degrees, and the entire long part of the canvas is on the left.

To put it simply, the ceiling plinth must be placed upside down (the part of the plinth that will adjoin the ceiling will be at the bottom in the miter box, and the one that will be glued to the wall at the top). Thus, we have made a left-side corner. For the right-handed one, we will turn our canvas over so that its longest part is on the right, place it a little further than the left slot with a mark of 45 degrees and also carefully cut it.

If, for some reason, the miter box was not at hand, but it is very necessary, then it can be drawn on the table. To do this, draw two parallel mowing lines along the table at a distance of about 20 cm; we connect them in the middle at a right angle and draw two more mowing lines that would intersect with the connecting line at an angle of 45 degrees (the intersection point of the three lines should be clearly in the middle of each). Next, we apply the baguette to the necessary mowing line and cut it according to the same principle as on the miter box.

Miter boxes. a device for easy and quick cutting of skirting boards.

Another way to cut the ceiling plinth correctly is by marking.

It is used when the angles are oblique or obtuse. The markup is done in this way: it is necessary to attach the ceiling plinth in the position in which it will be glued, and draw the line of its inner edge with a pencil on the ceiling. Next, we apply the second canvas on the other side and do the same manipulations.

Then we apply the canvases one by one and mark the intersection point of the inner edges of both canvases on each plinth. Well, the matter is small. we draw the line between the marked point and the opposite edge and cut. This method is very convenient when all the corners in the room are different, and templates and fixtures do not fit.

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), a small piece of plinth, a ruler and a good stationery knife if you work with polyurethane (polystyrene) baguettes or a metal saw for working 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 got 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). Having installed a piece of plinth in the corner, which will be glued 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 still won’t fold: the inner part will interfere. It can be trimmed later by trying on the ceiling. The second way is to place the piece to be cut on the table with the 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. Put it against the desired wall, rest 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 another way to make a corner of a ceiling plinth, and without a scribe or other special devices.

Using a 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 at the desired angle.

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

In the case of skirting boards, not everything is so simple: they must simultaneously adjoin two surfaces, therefore they must be pressed against one or the other wall of the miter box. When working with ceilings, they are pressed in 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. Trying 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, place the strip that will be located on the right on the right, the one on the left on the left.

How to cut a corner on a ceiling plinth: install it correctly in a miter box

With the part that is on the ceiling, press it against the bottom of the miter box. The other side is closer to you and raised. Lean it on the wall of the device so that it 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 outer or outer corner.

First put the cut-off parts in place “dry”, without applying glue. If the geometry of the corner is not so perfect, you can tweak it 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, try on which side will be on the ceiling, press this part to the bottom of the miter box, lean the second part on the wall closest to you and make cuts as shown in the photo below.

How to cut ceiling plinth in corners

The quality of the ceiling finish greatly affects the appearance of the room. Therefore, 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 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.

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 polystyrene skirting boards without special devices, they cut them with a good stationery knife. Its blade is quite thin and even, the cut is smooth, not wrinkled. If you use a saw with polyurethane or polystyrene, do not press hard: you can wrinkle.

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

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 they were installed on the ceiling with mortar. Such figured decorations were called fillets. Today, you can rarely see them: they are expensive, and outwardly they are almost indistinguishable from 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: you can arrange such a corner only using ready-made corners.

How to get the correct angle

Most of the problems when working with skirting boards arise in the design of corners. Since the surface of the products is complex, it will not be possible to simply cut off 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 your 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 there is a small distance 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 a corner in the way described above, try it on dry, adjust everything so that the result suits you. Only then can you attach the already cut strip to the corner and mark the place to which 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.

Choosing the corner shaping tool

The most economical option is to buy a simple plastic miter box. It is a plastic block with eight working slots. Such a device is designed for only two operations: trimming at 45, 90 and 22.5 degrees. An angle of 90 degrees is useful, for example, if you need to embed a socket in the middle of the molding.

Some fixtures come with eccentric clamps included. They are preferable, since it is easier to work with it. the plinth is clamped in the desired position and does not move during the cutting process. Accordingly, if flaws happen, then they are minimal and it will not be difficult to adjust the angle.

If you have to renovate your own home, then it may make sense to purchase a more serious tool. a rotary single-plane miter box. It is designed for cutting at 15, 22.5, 30, 36, 45 and 90 degrees. The design of such a miter box includes 2 clamps. for clamping in the horizontal and vertical planes, as well as a stopper that will allow you to cut the workpieces by one length. The hacksaw will be built in here. If it is not clear how to cut the ceiling plinth. the review below will help you.

Floor plinth: freehand inner and outer corner

Floor moldings are usually quite wide and thick, and therefore, finding only two points here, as for ceiling moldings, is not enough. To trim the inner corner, first set a point at its top at a height equal to the width of the plinth. in the figure, this is a green point. From it to the left and to the right we set aside a distance equal to the thickness of the plinth. points 1 and 2.

We apply the left segment to the wall, and from point 1 we draw a line along it, perpendicular to the wall and put a point on the edge. We repeat the action with the right segment, only drawing from point 2. In the figure, the point is marked with the number three. From it, across the plinth, draw a line to its opposite edge. we get point 4. Now we connect the green point with points 3 and 4. we get a line and an angle along which it will be possible to cut the molding.

By connecting these points with each other with one line, we get a fishing line along which a cut will be made.

We cut the inner and outer corners of the floor skirting boards

Cutting the floor moldings exactly is no more difficult than the ceiling moldings. Only the cutting tool is selected according to the material to be cut. The work itself will also be similar, only for manual cutting, a slightly different marking method is presented here.

Cut the corner with a miter box

Take a polyurethane skirting board designed for the left or right side of the corner. We lean it against the future installation site so that the end of the segment opposite from the corner is in the edge of the already glued molding. In the place where the lower edge of the ceiling plinth touches the top of the wall corner, put a point with a pencil or stick a piece of electrical tape. We repeat these actions with the second segment.

  • We place the left blank in the miter box from left to right, pressing it to the edge closest to us. The corner vertex mark must match the leftmost slot in the same edge
  • We place the right blank from right to left, pressing it to the near edge. Corner Vertex Mark. To Right Slot.

How to cut a ceiling plinth to an inner corner? Everything is very simple, the actions will be exactly the same, only the location of the corner vertex mark changes. Here, on the contrary: for the left segment. the extreme right slot, and for the right. the extreme left. Finished ceiling fillets must be combined, and then you look at the joints in the light. there should be no cracks. If they are very small, then editing is not needed, you can do with filling with putty after installation.

How to cut the corners of a skirting board without a miter box

If you are wondering how to properly saw down a ceiling plinth without a miter box, then the following information will be useful to you. We take the right segment of the ceiling plinth made of polystyrene, apply it to the installation site and draw a line on the ceiling along its upper edge. It should go beyond the points of the vertices of the corners by about 5 cm. Do the same with the left segment and put points at the intersection of the lines. We put the ceiling plinths in place one by one and transfer the resulting marks to them.

We figured out the upper part of the ceiling moldings, now we move on to the bottom. Everything is simple here, the marks we need are the tops of the corners. Mark their location with dots on the lower edges of the left and right ceiling plinths. Next, you need to connect the points on the moldings. this will be the trim line. This method will help to cope with even the most crooked corners. Adjustment is most likely not needed, and if it does, it will be minimal.

Cutting wood floor molding with a miter box

It is necessary to measure the distance from the edge of the skirting board already glued to the wall to the top of the corner of the wall. Now we take a new piece of molding and set aside a length equal to this distance on its lower edge. We put a point with a pencil or stick a piece of electrical tape. We do this procedure for both the outer and inner corners. In the miter box, place the skirting boards from left to right for the left side of the corner and from right to left for the right. In this case, they should be pressed as in the figure. to the side of the miter box closest to you.

How to cut a corner of a ceiling plinth. laying a workpiece in a miter box:

  • For the outer left, match the mark on the skirting board with the extreme left slot. For the outer right. from the far right.
  • For the inner left, match the mark on the skirting board with the extreme right slot. For the inner right. from the far left.

Clarification: the notch refers to the one on the side closer to you.
