How to cut a corner on a baseboard

Preparatory work

corner, baseboard

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

  • wood;
  • gypsum;
  • foam;
  • polyurethane;
  • Pvc.

Based on this, you need to prepare the tools. Depending on the material, a device is selected with which it will be easy to 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 of the irregularities of the work.

The higher the ceilings in the room, the wider the border should be. Otherwise, he will simply “get lost”.
Then, the surface is prepared to which the plinth will be attached. it must be dry, even and clean.

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

You only need to cut the corners on the 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 both through a slotted tray or in its absence by applying the necessary markings on the ceiling or on paper.

To dock 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 baseboard 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.

A miter box is a U-shaped tray with sides, in which slots are made for the cutting tool. There can 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 molding 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 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.

Skirting Corner Tools

Initially, you should decide what exactly to cut. If this is a light material. polystyrene, for example, 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 crayon or pencil will also come in handy, and when manually cutting a plinth, an angular ruler is required.

How to make an inner corner

  • Press the fillet to the inner corner in the way that it will be glued.
  • With a pencil, draw a line along the top 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 a 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 draw a 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 wall 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 plinth should also be installed 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 skirting board from the front side of the product so that the line is straight and clear.

How to make an outer corner

Just as the lines for trimming the inner corners were outlined, the outer corners need to 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 a 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 machine 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 have been 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 irregularities on them must be removed with a file.

Form, fittings

When studying the question of how to properly cut a corner on a ceiling plinth, you should pay attention to its shape and related products. There are embossed and smooth fillets. Their width and length can vary significantly.

When choosing the size of the skirting boards, take into account the type of interior, as well as the height of the ceilings. For a small room, where the distance from floor to ceiling is no more than 2.75 m, wide skirting boards will not work. They will look out of place. For the same reason, a narrow fillet should not be used for high ceilings. In such rooms, a 45 mm plinth looks good.

For installation, you can purchase curly corners from the same material as the fillet. They are external and internal. But quite often the skirting boards are joined without them, directly. In this case, you need to perform an even, beautiful trimming of the corners.

Inner corner

First of all, it is necessary to consider the technique of how to cut the inner corner of the ceiling plinth. After all, in any room they are. If there are no external corners in ordinary rectangular rooms, then these varieties will have to be cut in any case.

A plinth is placed at the bottom of the miter box with the side that will adjoin the ceiling. The bottom of the fillet will be pressed against the wall of the tray.

If the material is hard, it is cut with a metal saw. Soft items can be easily handled with a sharp knife. In this case, the angle should be equal to 45 degrees. If the pressure during cutting is too strong, hooks and chips will form on the plinth. An adjacent corner is cut in the same way.

Before gluing, they are applied to the wall and, if necessary, small irregularities are corrected. There should be no gaps between the skirting boards. If this is the first time this work is done, you can practice on small pieces.

General characteristics of finishing

Studying the question of how to properly cut a corner on the ceiling plinth, you should familiarize yourself with the features of such a finish. The stucco molding between the ceiling and walls is now made of artificial materials. It can be polyvinyl chloride, expanded polystyrene or polyurethane. Wood can be used from natural materials.

In the construction business, the ceiling plinth is called (scientifically) a fillet. Of all the materials from which such finishing elements are made, polyurethane is considered the highest quality. Therefore, it is better to choose it. Next, let’s try to figure out how to cut the corner of the ceiling plinth. Expert advice will help you do this job well.

Homemade tool

Don’t you have a miter box? No problem! You can do it yourself. When pruning for the first time, it is best to apply it in your work. This will require a plywood board, paper or cardboard.

Interested in how to cut the outer corner of the skirting board, as well as its internal varieties, you need to take this approach into service. Draw two parallel lines on the selected material. Next, using a protractor, angles of 45 degrees are made around the edges.

A homemade tool is applied to the plinth, making the appropriate notes. The pruning technique is the same. The miter box is not used if the walls in the room are very uneven. When creating an angle of 45 degrees, gaps between the joints are obtained due to such inconsistencies. Therefore, pruning is done in the previous way. Before editing, the edges must be corrected.

How to cut corners on skirting boards? Step-by-step instructions, practical tips and advice

Repair is a responsible and costly undertaking. Although you can save a lot if you carry out the work yourself. Cosmetic finishing of the premises is carried out according to certain technologies. You can decorate the interior using a variety of materials.

Today, a very popular technique is the use of skirting boards to hide irregularities between the walls and the ceiling. In order for the contour to be aesthetic, it is necessary to do the work carefully. How to cut corners on skirting boards will help you understand the advice of experienced construction and repair masters. They will tell you how, using various tools, to perform the necessary manipulations with decorative finishes of various types.

Outside corner

Quite often, the contour of the walls in a room has a complex shape. In this case, you will need to figure out how to cut the outer corner of the ceiling plinth. To do this, it is laid on the bottom of the miter box in the same way as in the previous version, with the side that adjoins the ceiling.

Other slots are used for these corners. They also have a slope of 45 degrees, but are on the other side. Further, after marking and trimming, 2 plinths are applied to the corresponding place on the ceiling. Adjustment in progress.

Difficulties can arise when it is necessary to cut the same skirting board on one side for the outer corner and on the other for the inner one. Many people make a mistake here. First you need to cut the inner corner. Otherwise, a skirting board that is too shortened will not dock in any place.

Work without a miter box

The polyurethane skirting board looks very nice in the interior. How to cut corners on such a product so as not to spoil its appearance? And here an inexperienced master will be helped by expert advice. Not always a home craftsman has at hand such a tool as a miter box. You can do without it.

For this, the markings are performed directly on the wall. First, the required length of the decorative item is measured. It is cut at right angles. Next, each detail is applied to the ceiling. Their contour is outlined with a pencil. This produces an intersection. It is applied to both skirting boards.

An oblique line is drawn from the point of intersection to the edge. This is the clipping boundary. Correct it before gluing by attaching both skirting boards to the corner. This is a fairly simple method, but even it requires a good eye and accuracy in work.

THE secret to installing baseboard corners PERFECTLY

How to cut outside and inside corner on the ceiling plinth with your own hands

The angle between the ceiling and the wall in houses and apartments is rarely ideal. In this case, installing a skirting board is the most practical way to close the uneven border and brighten up the space above your head. Fixing the finishing elements to the ceiling is relatively easy, for example, with the help of “liquid nails”. At the same time, it is not at all easy to make a neat joint with your own hands, and it is better to first familiarize yourself with how to correctly cut a corner on the ceiling plinth.

How to properly cut a ceiling plinth without a miter box

The marking of the corners of the skirting board joint can be done “in place” on the ceiling, and then the question of at what angle to cut the skirting board does not arise. over, it is possible to correctly cut the fillet without a miter box, however, to obtain corners without gaps, you need to work very carefully and accurately.

In this case, the design of the inner corner, the sequence of actions is as follows:

  • We put the plinth in place of its installation and draw a line along the edge of the fillet on the ceiling at the joining point. We carry out the markup with a pencil with a short, non-greasy line.
  • We carry out a similar procedure on the second side of the corner and we get the intersection of two lines.
  • Now we transfer the marking of the obtained point to both plinths. At the same time, it makes no sense to mark the cutting line, since it will not be possible to accurately apply it on an uneven surface, and pencil marks will remain on the part after trimming.
  • We place the skirting board on a wooden support in working position. For this, it is convenient to use a second plank, installed with an edge on the base. We look at the place of the cut perpendicularly from above and cut off the fillet, focusing on the mark and the opposite edge of the plinth.
  • Trying on the cut skirting boards in the corner. Pencil marks can be erased with a rubber band.

The outside corner is marked differently. The skirting board is applied to the installation site and a corner line is marked on the wall on its lower edge. Then a fillet trim is applied to the second edge of the corner, and a mark is made on the upper edge of the workpiece at the point of contact of the two profiles. The markings are transferred from the inside of the skirting board to the outside, and cutting is performed.

Note that in this case there are traces of a pencil on the ceiling, which are not always easy to remove. In addition, when cutting out each corner, the marking operation must be done in place. It will probably be easier to work with a 45 ° cross pattern on the cutting stand.

The workpiece can now be placed on the base and cut using the template. By the way, the layout of the template can be done taking into account the deviations of the corners in the room and get joints without gaps.

The right solution is to cut the outer and inner corner with a miter box

You might get the impression that the fillet just needs to be cut at a 45º angle and glued in place. However, doing so can lead to up to three mistakes:

  • make a cut at the wrong angle;
  • the cut will be uneven;
  • the cutting plane is not perpendicular to the ceiling.

In this case, the angle is less than 90 degrees.

If there is even one omission, the junction of two fillets will have unacceptable gaps and slots. At the same time, the use of a simple and inexpensive tool called a miter box solves all problems. By the way, it’s easy to make it yourself in accordance with the recommendations “How to make a miter box with your own hands, photos of homemade constructions”.

In the standard version, the miter box allows you to cut workpieces at angles of 30, 45, 60 and 90º, which makes it possible to smoothly cut both internal and external corners, as well as to evenly join fillet pieces. For cutting materials such as expanded polystyrene, you can use a pistol knife with a blade width of 18mm, for working with wooden baseboards and other materials, a hacksaw for metal.

The inner corner in rooms is much more common, so from it we will begin to act according to the following plan:

  • First, you need to mark the fillet along the length, attaching it to the wall in the appropriate place. If this is not possible, you will have to use a tape measure. The mark is applied with a pencil, and so that it does not remain on the fillet after trimming.
  • The workpiece is placed in the miter box so that it is in the working position. The edge of the plinth, which will be on the wall, should be at the top, and the side that should be on the ceiling falls on the bottom of the miter box.
  • Now insert the hacksaw into the rails at an angle of 45º so that after cutting the edge on the ceiling is shorter than the edge on the wall. With our left hand we press the workpiece to the miter box and carefully cut the fillet, trying to prevent the material from chipping.
  • We also cut out the second part of the corner along the guide located at 90º to the previous cut. To do this, place the workpiece on the opposite side of the miter box.
  • Trying to connect the parts in place. If there is a gap, we carry out the correction with a file or a knife.
  • If the skirting board has a colored coating, the place of the cut must be tinted with the same color, otherwise the joint will be visible. Fillets can be glued in place.

The outer corner is cut in much the same way, but if the same part has both kinds of corners, the inner corner is cut first. We act according to the following plan:

  • When marking the external joint, it should be borne in mind that the part will be longer by the amount of the plinth width.
  • The workpiece is placed in the miter box so that it is in the working position. The edge of the plinth, which will be on the wall, should be at the top, and the side that should be on the ceiling falls on the bottom of the miter box.
  • Now insert the hacksaw into the rails at an angle of 45º so that after cutting the edge on the ceiling is longer than the edge on the wall. With the left hand, we press the workpiece to the miter box and carefully cut the fillet, trying to prevent the material from chipping.

This is followed by the same operations as for the device of the internal joint. Unfortunately, it so happens that the corners in the room are not equal to 90º, and the joints are obtained with gaps.

In this case, the problem is solved by a professional saw with a miter box, which allows you to cut the part correctly at any angle. In its absence, the cutting angle can be adjusted by installing spacers between the fillet and the miter box. In this case, the thickness of the spacer must be greater than the compensated gap as many times as the distance from the spacer to the cut is greater than the width of the plinth.

Choosing fillets on the ceiling

Ceiling plinth, another name for fillet or ceiling corner, can be made from various materials, as well as have a wide variety of shapes and sizes. Starting with the appearance, you should choose the height of the profile of the finishing elements in proportion to the size of the room. So, for a room with a height of 2.7 m, a plinth with a height of 50 mm is suitable. In rooms with a height of 2.5 to 3 m, finishing elements from 40 to 80 mm, respectively, will be appropriate.

A great choice. durable and moisture resistant polyurethane fillets. At the same time, they are not recommended for use in the kitchen, where, under the influence of changing temperatures, the finish can deform.

Fillets made of wood are distinguished by their environmental friendliness and time-tested. However, wood can warp and change its size under the influence of fluctuations in temperature and moisture in certain rooms. The relatively large weight of such products makes them difficult to mount at the top. Docking wooden fillets is more difficult than those listed above. In the absence of experience in installing a plinth, it is better to purchase it with a certain margin, since mistakes are inevitable.

Other ways to align corners evenly

It is very simple to join the profile in the corners with the help of special decorative corner elements. Unfortunately, not every skirting board can be matched with the necessary components.

over, the design of such elements is not always consistent with the overall interior of the room. On the contrary, in a certain situation, special corners will serve as a decoration of the room.

How To Cut Baseboard Corners That Look Great

How and what to cut a plastic skirting board

All of the above applies to MDF and wood skirting boards. Cutting them with an ordinary hacksaw is not a problem. It is advisable to take a blade for metal, since it has a smaller tooth and the saw cut is smoother, you will have to work less with sandpaper. With plastic, the situation is different. when you try to cut a piece, some thin-walled skirting boards crumble and break.

Cutting plastic is not very convenient because of the thin walls

To cut normal quality plastic skirting boards you can use:

  • Hacksaw for metal.
  • Grinder (angle grinder) with a diamond disc.
  • A revolving miter saw. Before cutting, speed up the disc and only then start cutting.
  • A jigsaw and a file with a fine tooth. Here you have to try. select the speed and file.
  • Sharp knife.
  • Metal scissors. In any case, it is not difficult to make straight cuts with them.

Only personal experience will help you decide what is more convenient for you to cut a plastic floor plinth. If you have a miter saw, try using it. It’s not a problem to try a grinder with a diamond blade a couple of times. If all this does not work well, try a hacksaw, jigsaw, or knife. There are, of course, special scissors for plastic, but they are too expensive to buy for a single use.

Accessories for the design of corners and joints of PVC skirting boards

In plastic skirting boards, you can design corners and joints using special fittings. There are external and internal corners, plugs and connectors. Basically, they allow you to assemble the desired configuration. Each manufacturer makes its own fittings. for its own profile, colors. But the principle of their use is the same.

How to shape the corners of a plastic skirting board

The first rule is that all cuts are made straight. Strictly perpendicular. Marks in the corners are set at a distance of 1-1.5 mm from the corner. The fact is that the rigidity fittings have their own jumpers. For them, it is necessary to retreat a couple of millimeters, but no more. Otherwise, a gap will appear or the skirting boards will pop out of these corners.

This is the result of the assembly

I must say that not everyone likes the look of plastic corners. You can make a corner on a PVC skirting board in the same way as described for wood or MDF. The only difficulty is that you have to be careful with plastic. it breaks down from excessive efforts. There is one trick. before cutting the plastic skirting board, add a little polyurethane foam on the back side and wait for the polymerization to begin. It will be tougher, easier to cut, less deformation. If the foam subsequently interferes, it is not a problem to remove it, but to cut it is, indeed, easier.

Miter box for skirting boards

A carpenter’s miter box is a device for cutting at a certain angle. It is used with a hacksaw. In principle, you can make a miter box yourself by assembling a guide from the boards and making cuts in the walls. There are various models on sale, ranging from 15 to several hundred dollars. They differ in capabilities, materials, although all are called “miter box”. Professional models are made on the basis of a good hacksaw, have a scale that allows you to set the saw as it should. With such a tool, it is not a problem to set any desired cutting angle in order to correctly cut the skirting board for a perfect fit.

Install Perfect Outside Baseboard Corners/Easy Math Trick

Professional carpentry miter box. a tool with a wide range

The simplest miter box is a plastic U-shaped profile, in the walls of which slots are formed. These slots are used as a hacksaw guide. They do not allow the canvas to deviate. In any case, there are two cuts. straight and at 45 degrees. Some may have a couple more options.

How to cut a plinth at 45 degrees? One way is to use a miter box

Sometimes a hacksaw is included, sometimes not. Usually the ones included are not very good. Any hacksaw can be used, picking up a blade for the material that is planned to be cut. It is important that the blade moves freely in the slots.

How to cut the skirting board correctly. Miter box for cutting corners

When installing skirting boards, it is important to arrange the corners correctly. It is they who often spoil the overall picture. How to make a corner on the plinth. external and internal, how and with what to cut. We will discuss all this further.

How to make a skirting angle more or less than 90 °

Not all angles are exactly 90 degrees. If the deviation is small, the cracks can be removed with sandpaper. In other cases, you will have to mark and cut taking into account the real degree. The main task in this case is to find a point on the floor where two plinths will join.

Let’s start by explaining how to properly slice the outside corner if it’s not 90 degrees. We take the bar, put it to the corner on one side, press it tightly against the wall. as it should stand. Draw a line on the floor with a pencil along the bottom edge of the plinth. We apply the bar to the other side of the corner, do the same. The intersection of the two lines will be the joining point of the two skirting boards.

How to join a skirting board if the angle is less than or more than 90 degrees

Now we attach the plinth strip again, set it in the way it will be attached. We make two marks: at the top at the turn itself, at the bottom in the place where the lines we draw intersect. Now an important task: it is necessary to make a cut according to these marks. If you have a miter saw or a miter box with an adjustable saw tilt, set it up and cut it. If not, carefully cut it with a hacksaw. In order not to get lost, you can draw a line with a pencil along which you need to cut. Similarly, mark and cut off the second part. Modifying the connection of the skirting boards with sandpaper.

Few of the professionals process the joints with sandpaper. this is time and additional work. But if you join skirting boards in the corners in your own house, with your own hands, you definitely want everything to be beautiful. This is what this manual debugging is for.

With a custom-sized inner corner, everything is exactly the same. We put a plinth in the corner, draw a straight line on the floor. We do it on the other side. Transfer the point of intersection to the planks.

How to cut the skirting board in the inner corners: an action plan step by step

Begin installing the skirting boards in one of the corners. If this is your first experience, choose the part of the room where something will stand. Not always, it’s over, the first pancake is lumpy, but it’s still better to insure yourself. To make the corner on the baseboard neatly, work slowly. One was sawed off, checked, adjusted. Let’s move on to the next one. It is better to fix it after the two adjacent corners are assembled. But you shouldn’t postpone the assembly too much.

Trimming skirting boards in corners requires some skill. But by making several joints yourself, you can beautifully design complex corners.

How to use a miter box to cut skirting boards? Place the device in front of you, preferably on a table, but also on the floor. It doesn’t matter which side to turn it, it is symmetrical. Insert the bar into the profile, turn it so that it will stand against the wall. When washing down a floor plinth in a miter box, the “wall” is the wall that is farther from you. Once again: press the plinth strip firmly against the back wall in the position in which it will be installed. Insert a hacksaw into the desired slots. You can start sawing.

How to saw down the corner of the plinth at the right distance

The second and all other corners of the skirting boards must be made at a certain distance. If the next corner is again internal and the distance to it is less than the length of the plank, use the same fragment on which there is already a cut. We measure the distance with a tape measure. strictly from corner to corner. Then this distance is laid on the bar using the same tape measure. We combine the beginning of the measuring tape with the ledge, measure the required distance, make a mark with a pencil. She will be the starting point for the cut.

You need to know at what distance to cut

Plinth with a mark is placed in the miter box, the desired direction of the cut is chosen. The dash can be combined with a hacksaw blade or with a slot in the miter box. As it is convenient for anyone. Cut off. This segment must be “tried on” in place. If both corners rest against opposite walls or the gap is only 1 mm, everything is fine. You can cut a second strip from a new piece to design a joint. And again we remove the flaws with sandpaper.

If the length of the wall is longer than the length of the plinth strip, take a new strip. We will cut the second corner on it. It is important not to be mistaken in which direction to cut. Having installed both planks along the wall, mark the joint on one of them, make a straight cut. For a straight cut, there are also slots in the miter box. So there won’t be any problems.

How to connect two skirting boards in a straight line

But the joint in a straight line does not always look perfect, and during operation it often diverges, forming a visible gap. If you wish, you can cut off at an angle (any) two planks.

To do this, first cut off the edge of one plank at an angle, mark the second joint. The mark is placed on the side of the plinth that is pressed against the wall. At this mark, we saw off another section, without changing the position of the saw relative to the miter box, but inserting the bar on the other side. The joint is oblique. It is more accurate. The difference is especially visible on wooden skirting boards and MDF. Cut, again, to bring “to mind” with sandpaper.

Making an external joint

In apartments or houses, there are not only internal corners, but also external ones. In this case, the nearest inner corner is first trimmed and modified. When it’s ready, you can make an outside corner on the baseboard. We put the bar in the corner, as it should be. In the place of the outer corner with a pencil, we make a mark exactly at the place of rotation.

How to make the outer corner of the skirting board

Then we transfer the bar to the miter box, choose the appropriate position. In order not to be mistaken, all the time imagine how the plinth is against the wall and what you should get.

We cut the second segment at 45 degrees so that it joins the finished one. To do this, we change the position of the saw to the opposite and start the plinth on the other side.

Types of corners in rooms

When installing skirting boards, you need to arrange the corners in some way. By their appearance, corners are external (which protrude forward) and internal (for example, corners in a room). In rooms with normal geometry, the corners are straight, i.e. 90 °. When joining two pieces of the plinth strip in the corner, they are cut so that each has an angle of 45 °.

To arrange the outer and inner corner, the skirting board must be cut

But how to make an angle on the plinth so that it is exactly forty-five degrees? To do this, use a special carpentry tool. miter box.

Outside corner

  • Measure the length of the plinth from the nearest wall to the outer corner, leave a line on the wrong side with a pencil, indicating the desired length. It should be noted that the edge (its upper part) should protrude slightly outward.
  • The plinth is moved to the miter box and cut off.
  • 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 are irregularities at the joints, you can trim the edges with an ordinary knife to a perfect fit.

Checking the smooth docking

All the nuances are well described in the video:

Method two. no additional tools

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

  • Apply a fillet to the ceiling, firmly pressing its even edge into a corner.
  • Draw a line along the long side of the plinth on the ceiling.

  • The same action is done with the adjacent part on the other side.

  • Mark the point of intersection of lines.

The end result is an even 45 ° angle when you draw a line from the intersection to the edge of the part. Note that the above marking method works only at perfectly flat corners.

The first way is with a miter box

Professional miter box with rotary hacksaw

The miter box usually looks like a tray with vertical holes for a hacksaw. It can be made of wood, metal or plastic. This tool is the oldest and simplest carpenter’s tool for cutting wood pieces at 90 ° and 45 ° angles. There are types of such a device for professional work, with a rotary mechanism, in which the cutting tool can be rotated and fixed in any position.

How to cut a ceiling plinth correctly

Ceiling corners are divided into internal and external, the method of joining them is slightly different.

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