How to cut ceiling skirting boards yourself. How to make the corner of the ceiling plinth with the help of a miter box and improvised means. Description of the process with photos and videos. Ways to form correct angles

Surely, each of us at least once faced the question: how to cut the corner of the ceiling plinth? Well, or outdoor, depending on the situation. Of course, there are ready-made connectors on sale, but it is not always possible to choose one for each specific type of molding.

And now you have to somehow get out, trim by eye, and then correct several times. But cutting the molding correctly the first time is not so difficult. In this article we will tell you how to file ceiling plinth as well as outdoor. One - with the help of a special tool, and the other - without it.

We cut the corner of the ceiling plinth with a miter box

As described above, trimming a corner can be done both with the help of a special tool - a miter box, and without it. The set of other items that you will need is the same in both cases: a hacksaw, a cardboard knife, a goniometer and a pencil, a stepladder.

Which miter box is better to buy for trimming

This article will describe how to work with the simplest miter box, such as the one on the left side of the photo. It is possible to cut the plinth at an angle of 45 and 90 degrees on it - this necessary minimum. And on the right side of the photo - a rotary miter box. Its device is more complicated, includes a built-in hacksaw and allows you to cut the material at different angles. Of course, this option is more convenient to use and provides more trimming options.

However, if you are not the owner of a private house where you periodically have to do carpentry, then it would be better to do the most simple option. For comparison, an ordinary miter box for a ceiling plinth costs 100-350 rubles, and after the repair is completed, it can be thrown onto the balcony or thrown out altogether. A swivel can cost from one and a half thousand, plus it must then be stored somewhere in proper conditions.

How and with what to cut a plastic plinth: an ordinary and a rotary miter box

There is another way to cut down the ceiling plinth. Video on how to cut a baguette with a miter saw. In addition, you will find several useful tips and for cutting on an ordinary miter box.

Note:before making the first cuts, you need to carefully measure the skirting boards. This way you avoid unnecessary spending.

Start trimming: inner corner

We take the ceiling molding, which will be located on the left and lay it in a corner so that it is tightly pressed against the opposite wall and correct, if necessary, the length of the segment. We mark in any way the side that looks down.

Now let's go to the miter box: the ceiling molding is placed in the appliance on the right, with the bottom side closer to you. We place the hacksaw from right to left. Now you can cut the corner. In the diagram, this is the left side of the figure. We also do trimming for the right molding.

Trimming the outer corner of the ceiling molding

Here we act according to the same plan as when trimming the inner corner: we apply it to the wall - we check the correspondence of the length - we mark the point of the top corner of the wall on the lower edge of the baguette - we go to the miter box.

For cutting outer corner ceiling moldings are placed in the device in the same way as for the internal one. We only make an adjustment for the point of the top of the corner, which we set on the baguette. It must match: with the leftmost slot for the left ceiling plinth, and for the right one, respectively, with the rightmost one.

How to cut a corner of a ceiling plinth: correct position baguette

Note:in the article we describe each stage, starting from the left side of the wall. However, in reality this of great importance does not have. You can start working from any direction.

Trimming the corner of a ceiling molding with a large pattern

Sometimes the pattern on the surface of the curb is very large, and falls just at the joints in the corners. In this case, we have to puzzle over how to cut the corner of the ceiling plinth, and combine the sides without violating its overall composition. In fact, there is nothing complicated here:

We cut out a section with a pattern from the ceiling molding + 5 cm on each side.
We divide the resulting segment in half.
Now we do the markup and trimming as described above.

If there are minor flaws in the connection, we mask them with putty, after mounting the baguette on the wall and the glue has dried.

We make pruning without a miter box

If you do not have the opportunity to get a miter box, or the angle of the wall is much more or less than 90 degrees, then you will have to do some drawing. This business will require maximum concentration from you, but rest assured, you can handle it.

Shaping and cutting corners

For the outer corner, we apply the ceiling borders alternately, each to its own side, and draw a line along them on the ceiling and walls. Thus, you can even make the docking of three skirting boards at once, as in the photo. As a result, we will get several intersection points, as in the photo below. Next, we transfer these points to the moldings themselves and draw lines from the top to the bottom. Thanks to these lines, it will become clear to you how to cut the ceiling plinth correctly.

Note:trimming and installation of the ceiling plinth must be started before the start fine finish walls and ceiling. So we can safely make the necessary marks on the walls and ceiling, without fear of spoiling the coating.

How to saw down a ceiling plinth for an external corner

To trim the inner corner, we also have to “draw”. As in the previous case, we apply skirting boards and draw lines along them, looking for intersection points. We put them on the ceiling moldings themselves and draw cutting lines. In the figure, we look at the red lines, black are given in order to make it clear where the joints of the walls and ceiling are.

The final touch before gluing the plinth

Now we just have to check how accurately the trimming is done. To do this, we pick up the left and right parts of the ceiling plinth, and then join them in the corner. If there are no gaps, you can start gluing, if there are defects, we trim with a hacksaw or a cardboard knife. The check is carried out in the same way for both external and internal corners.

Note:top-bottom markings on moldings are best done with masking tape. It is easily removed after trimming, while traces of a pencil or marker will have to be masked. This is especially important if the plinth is not supposed to be painted in the future.

We join the corner elements of the ceiling plinth and check the quality of the trim

Trimming the floor plinth with and without a miter box

We prepare the same set of tools as for working with a ceiling plinth, but with minor changes: we add a small ruler, and we won’t need a cardboard knife. As for the type of miter box, the selection criteria remain the same.

Forming an inner and outer corner with a miter box

To trim the inner corner, we need to measure and cut the left molding to the desired length, and then mark its bottom edge. And now we lay the floor plinth in the miter box: turn the lower edge towards you and press it against the side of the miter box closest to you. The hacksaw blade should move from right to left during cutting. We also do the trimming of the right plinth, only the placement in the miter box and the direction of the hacksaw are mirrored to the left.

How to fit a wooden or polyurethane baseboard under outer corner

Trimming the outer corner is done in a similar way, only on the lower edge of the molding we mark the place that falls on the corner of the wall. In the miter box, we place the plinth so that the point coincides with the leftmost or rightmost slot in the device on the wall, which is closer to you. To cut a place under the socket on the floor plinth, we saw the bar at a right angle, along the central slot. This is the end of the job. Now you know how to cut the baseboard in the corner.

The diagram shows how to use a miter box for cutting floor skirting boards.

How to make pruning without a miter box?

We take the right and left plinths in turn, tightly put each of them into the corner, and put points on the wall as shown in the figure.
We take the right side, apply it to the wall, and from point "2" draw a line perpendicular to the wall, put point "3" on the molding.
We apply the left side, and we also set the point “3” on it.
We draw borders along the floor along their lower edge, mark the place where the lines intersect. We mark the point on both moldings.

Now you need to draw lines along the plinths from the mark "4" to "3". We trim so that on one side the hacksaw blade goes along the “3-4” line, and on the other hand, along the opposite edge of the board. In the photo, this edge is marked with a green dot.

And now about how to cut the plinth in the corners of the outer. We draw the lines of the edge of the corner on inside baguettes. Next, draw the underside of the skirting boards on the floor. We transfer the intersection point to the plinth, and then with the help of right angle rulers - on the opposite edge of the board. So we got the trim lines.

How to connect the inner corner and make the fitting of the elements

High-quality repair requires an attentive and accurate attitude to the details. Finishing work with the ceiling, you need to arrange it well - ceiling plinths are used for this. As a rule, the installation of planks does not cause any particular difficulties; you will have to tinker with the corners. Let's take a closer look at how to cut a ceiling plinth in the corners, let's talk about different ways, let's give useful advice on this topic.

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

What tools will be needed?

For a ceiling plinth, the following tools may be useful, depending on the chosen method of work:

Saw on wood. Useful for working with wood.
Canvas for metal. Suitable for other types of skirting boards (foam, plastic, etc.).
Miter box. The tool is a gutter, which has the shape of an inverted P, where lines for cutting are outlined at angles of 45 ° and 90 °.
Electrical Miter saw. Can be used instead of a miter box, helps to achieve high precision cuts.
Electric jigsaw. It is easy to operate, with the help of it you can qualitatively and correctly cut a corner without burrs.
Stationery or construction knife. Suitable for foam skirting boards, it is important that it has an excellent cutting blade and therefore must be well sharpened.

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 maintain a good fit, preferably without huge gaps. How to make a corner on a ceiling plinth? You can use several methods: with a miter box, without a miter box, using decorative corners, as well as in an alternative way.

With their help, you can easily and quickly obtain the desired angles in polystyrene or polyurethane skirting boards. Install them on the ceiling, and then glue the strips tightly to them. Cutting them is easy with a utility knife.

How to make corners of a ceiling plinth without tools

Make the necessary marks on the baseboards.
Using a ruler, connect the edge of the skirting board with the mark. If you just cut along the line, the pieces in the corner still won't fit together because the inside will get in the way. You can trim it later by making measurements on the ceiling.
You can lay on the table the piece to be cut, the part that will be located on the ceiling, and cut at an angle of 45 degrees. It needs some adjustment, but less.
Repeat steps 2 and 3 for the second plank, making the outer corner.

Thus, you can make a ceiling plinth without special tools, using improvised means.

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

The baguette, which will be fixed on the left, must have a right cut, the right baguette - the left one. When creating the inner corner, make sure that the bottom section rises above the top one, 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.

When a certain part of the plinth is glued and a small distance remains to the corner, in order 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 convenient way, try it on a dry surface, put the bar on the ceiling and select the place to which it needs to be shortened. Cutting is performed at an angle of 90 °.

Next, you need to correctly dock the corners. Made ceiling moldings are attached at an angle of 38-45 °, so the classic 45 ° is not always suitable at the junction. AT different occasions cut edges do not meet and leave gaps. For this reason, after the initial trimming of the corners, it is necessary to carry out a “dry” and most accurate docking of the baguettes directly on the ceiling. You will especially have to tinker with wooden and plastic materials.

After completing the rough docking of the skirting boards, glue or screw the fillets to the walls and ceiling, then, if necessary, use putty and seal the seams at the end.

Important Points

Consider how to properly cut the corners of the ceiling plinth and get it right the first time great result. Follow a few helpful tips:

Before mounting, both parts must be adjusted to each other. Attach both halves to each other. The wall surface must be dry. Having found defects, you can easily align them with a knife.
It may need a few trims. Don't be discouraged if it takes you a long time to do a few trims, especially if this is your first time doing the job.
Correctly determine the length of the strips in the corners. For an inner corner, the length of the plank should be adjusted exactly from corner to corner; for an outer corner, the measurement is taken from the inner point in the direction of the room.
If the corners as a whole match perfectly, but there are small gaps in the middle, they can be repaired with putty.

How to glue a ceiling plinth

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

Water or soil is applied to the fastener areas. After the putty mixture has dried, all cracks must be sealed - various sealants are used for coating (professional builders recommend choosing products based on acrylic). In general, one package is required per room. Installation with a sealant is carried out in the same way as when using putty.

How to cut corners on baguettes (ceiling plinth) video

Installation of skirting boards is the final stage of the repair of the premises. Neatly installed ceiling and floor planks transform the space, the interior takes on a finished look. But if the sticker of skirting boards on straight surfaces does not cause any serious difficulties, then docking and cutting the skirting board at an angle sometimes turns into serious tests.

In the article we will present several ways how to cut a skirting board in the corners, how to properly join the planks, how to cut and connect corner details narrow and wide, figured profiles. And we will also tell you how to cover up the joints, what tool will be required for installation, and what tricks exist to properly bring the outer and inner corners together. Also watch the video tutorials, which show in detail how to cut and connect corners in skirting boards from different materials.

There are several options for how to cut the corners of the plinth, the traditional way is to wash down the corner by 45gr

About corners

The installation of skirting boards is one of the final stages of repair, it is very important to perform the installation carefully, without gaps, and the most difficult thing in this process is to join and fit the planks in the corners. If the surfaces are perfectly aligned, then it is not difficult to connect the skirting boards, it is enough to file the ends at an angle of 45º, and then fix them in place. But in most cases, the geometry of the premises, to put it mildly, leaves much to be desired, sometimes instead of an angle of 90º, in practice the walls are adjacent to each other and with an angle of 87º and 93º, and even the ceiling went up or collapsed. Under such conditions, cutting and joining skirting boards at the corners turns into an exciting activity full of puzzles that requires extraordinary ingenuity and patience. Next, we will tell you how many ways to cut the plinth in the corner and dock the planks evenly.

Method Oh! Lucky!" We cut the plinth with a miter box

Before cutting the corner of the ceiling plinth, measure the corners of the room with a building corner, if they are straight, then cut the corners so that they fit snugly, without a gap, in the corner using a miter box.

The miter box for cutting the ceiling plinth is a simple carpentry fixture for cutting, consisting of a tray with a rim to hold the bar in one position, and with grooves that guide the blade cutting tool at the desired angle: 45, 60 and 90º.

In order not to get confused in the sides of the plank and there is no question of how to cut off the corner of the ceiling plinth, attach the plank at the installation site. Mentally fix the position of the plinth, and without turning it over, install it on the miter box. The part that will be glued to the wall should rest against the side. If you applied the plinth on the left, then you need to cut from the left end, and vice versa, respectively.

Photo instruction on how to cut the corner of the ceiling plinth, internal pairing

Important: To cut off the inner corner, the bar is applied to the far wall of the miter box. In order to cut off the outer corner, the plinth rests against the near edge.

If the plinth is made of foam plastic or loose polystyrene, then it is better to cut it off with a sharp knife, you can use a stationery knife, more rigid materials: polyurethane, dense polystyrene, pvc are recommended to be cut with a hacksaw for metal with small teeth.

External corner, photo how to properly cut down the ceiling plinth

The cut ends, for a snug fit to each other, must be processed with a file or sandpaper, after which the profile can be installed in place. To catch all the nuances of installation, be sure to watch the video on how to saw down the ceiling plinth, the video instruction shows how and where to apply the profile in order to make the right cut.

Buying a miter box for cutting at one time is completely impractical, so you can make a fixture yourself. For this you will need a base part. rectangular shape, from plywood or chipboard, for the sides - bars, all elements are aligned, the bars are installed at the edges, their parallelism is checked, the parts are fixed on self-tapping screws. Next, the angles are marked along the protractor, an angle of 45º can be measured using a square sheet folded diagonally.

A 60º angle is also very easy to make. From school course it is known that the angles in an equilateral triangle are 60º, draw a triangle with the same sides on paper, cut it out, this will be the template by which the cuts are made.

Before sawing the ceiling plinth, check the corners, if they are 90g, use the miter box

We only dream of peace, or how to make a corner of a ceiling plinth if the walls are apart

If the walls in the room are connected according to the "universal" tool of builders - "by eye", so as not to spoil the interior of the room, you should correctly measure and cut the corner. For cutting, you need a bevel - in fact, this is a folding square that you can buy in a store, and it’s also easy to make it yourself. To do this, you need 2 even rails, 20 mm wide, 200 mm long, as well as a tie-bolt. The ends of the rails are cut at a right angle, then the strips are folded together, aligned, rounded from one edge, the rounding radius should be equal to half the width of the rail. Next, a hole is drilled with a drill, and the rails are pulled together with a bolt.

Before cutting the corners of the ceiling plinth, measure the mating of the walls with a small

When the bevel is done, measure the angle by pushing the slats to the sides, both parts should rest against the walls, fix the position by tightening the coupler bolt more tightly. After that, attach the Malka to a thick sheet of cardboard, outline the outer contours of the corner, and cut out the paper template. Fold the resulting figure in half, evenly connecting the edges, so you will find the middle of the corner. Further, for convenience, transfer the template to MDF, plywood, HDF, do not forget to mark the middle, carefully cut out a new template along the contour, along which the internal corners will be cut. To file external corners, you need to cut out your own template, for this, the corner is “covered” with a small one, and internal parameters are transferred to the template.

First, the plinth is applied on one side of the template, the marks are transferred to the bar, connected by a line along which the cut is made, then the second plinth is measured and cut in the same way, the ends are processed with an abrasive, and glued in place.

How to properly cut a ceiling plinth using parallel lines

Even if there is no angle of the curve, there is no miter box, and you don’t really want to do the malka, then even in this case there is an effective and reliable way how to cut a ceiling plinth. Attach the skirting board to the installation site, make a mark according to the dimensions of the plank on the ceiling and wall. Do the same around the perimeter of the room, from all sides.

To correctly combine the corners, transfer the dimensions of the plinth to the wall and ceiling, draw parallel lines along the marks

Draw parallel lines along the marks, they will intersect in the corners and form rectangles. The intersection on the ceiling is the upper cut mark, on the wall is the lower one. Attach the plinth again, and transfer marks to it, connect the points with a straight line, this will be the cut angle.

Transfer the intersection points of the lines to the plinth, connect them exactly along the line, cut

How to cut the corners of a floor skirting board

As for the question of how to cut a corner in floor skirting boards, the methods of measuring, cutting and joining corner elements to the floor are no different from mounting ceiling profiles. The only difference is that when cutting on a miter box, the side that will rest on flooring, and the leg that will be adjacent to the wall should lie on the base of the fixture.

Another difference between the installation and cutting of floor and ceiling plinths lies in the shape of the fillets. So the ceiling baguette often has an almost isosceles shape in the base section. right triangle, sometimes one of the legs is slightly smaller, but this difference is not significant. But floor profiles, especially wide ones, on the contrary, have a small leg-base resting on the floor, and an elongated leg resting on the wall. The floor plinth along the lower leg, as a rule, is no more than 23 mm, and they differ greatly in height, from 25 to 300 mm, sometimes higher.

Cutting and sealing the outer corner floor plinth identical to the fit of the ceiling fillets

Some stylish interiors require the installation of high profiles, and in such cases, cutting the inside corner traditional way not relevant. To cut and join a high and narrow profile, the first plank should be sawn at a right angle, and fixed in place. Next, you need to cut off a piece of plinth at a right angle. The second plinth, which will be joined perpendicular to the first, should be laid flat, then put the prepared piece on the edge with the butt end, and carefully outline it along the contour. The resulting drawing must be cut out, exactly along the line, and then clean the end face with sandpaper. The plinth cut in this way will exactly repeat the contours of the already fixed profile, and will fit snugly into place.

The way to properly saw and join a tall but narrow baseboard

How to make corners beautiful

When the fitting and installation of skirting boards around the perimeter is completed, it is necessary to close up all the flaws in the corners with putty. For wooden skirting boards can be used wax pencil, or a special putty on wood. After the repair compound dries, a decorative finishing layer is applied on top.

Before cutting the plastic plinth, measure the distance and subtract 2-3 mm on each side so that the strips freely enter the docking parts

But the repair industry does not stand still, and today you can not suffer with cutting and fitting the profile at the joints. So for polyurethane, polystyrene and plastic skirting boards, there is a special decorative connector on sale that masks the corners and junctions.

Polyurethane corner elements for the ceiling plinth can not only hide the joints, but also significantly transform the interior of the room. For floor plastic skirting boards, ready-made corner parts and matching mating strips are sold in the kit, they are almost invisible during installation.

How to join the corners of the ceiling plinth using auxiliary decorative elements

We described in detail how to use a miter box and a bevel for cutting a profile, considered several ways how to cut a ceiling plinth, video and photographic materials selected for the article clearly illustrate all stages of the process. Before gluing the plinth, prepare the surface, it must be flat and dry, without dust. After cutting off the corner pieces, be sure to check several times whether they fit snugly together, if necessary, cut again or modify with an abrasive. If you follow the saying: measure seven times, cut one, then high-quality and neat, without gaps and masses of putty at the joints, installation of skirting boards is guaranteed to you.

Profile fastening is one of the most important and responsible processes in the installation of a stretch ceiling. With high-quality and durable installation, the structure will last for many years and cannot be deformed: the canvas will not sag, the profile itself will not break. But it also depends on the fastening of the baguette appearance ceiling, with different types profile produces a special result. For example, when using an invisible profile (profile for harpoon and beading methods), the gaps that remain between the wall and the canvas should be additionally masked with a plinth or decorative tape. If you attach a visible profile (clothespin profile), then you should be very careful not to damage it, because it also acts as a decorative plinth. You should be careful with the corners while cutting, because the appearance of the stretch ceiling depends on it.

Profile mounting

First of all, you should first prepare for the installation of a baguette and a stretch fabric:

Fig.1. Fixing the baguette to the wall

It is necessary to free the room from furniture, plants and other items. Nothing should be located at a distance of 1 meter from the wall, because this will interfere with the installation. If some furniture or other interior items cannot be taken out of the room, then they should be covered with a protective material.
To speed up the installation process itself, you should drill holes in the profile or purchase already. Remember that a plastic baguette is drilled into a square edge, and a metal baguette into a panel.
Next, mark a line around the perimeter of the room along which the profile will be equal. You need to do this with a level.

Before starting the installation, it does not hurt to look at the room and find out where there is a large concentration of wires, a loose wall, and so on.

Sawing corners on a baguette

The installation of the profile should begin from the most inaccessible corner, for this you need to cut out the inner and outer corners of the baguette stretch ceilings:

Fig.2. Washed down a baguette for mounting the ceiling in the corner

Turn and rest the profile with the back side against the wall and draw a line on the profile at a distance of 1 cm from the corner. Then carefully file the back wall of the profile, without damaging the front wall of the baguette, carefully bend it into the shape of an angle - the inner corner is ready.
To make the outer corners of the baguette of stretch ceilings, you need to attach the profile to the wall, and draw a straight line at a distance of 2 cm from the corner, the first notch will be in this place. Then, at the junction of the baguette with the corner of the wall, you must also draw a line, so these two marks will be parallel and located at a distance of 2 cm from each other. Now you need to cut out this part and carefully remove it with pliers, then bend the profile - the outer corner is ready.
Using a baguette on curved sections of the wall, on the back side of the profile, you need to make several parallel cuts at the same distance and carefully bend into the desired shape. A mouthpiece should be installed on the sawn part of the profile.
After installing the baguette in the corners of the room, stick adhesive tape on the joints, thus processing them. It is most convenient to make cuts with a hacksaw.

Fig.3. Washed down the inner corner for the installation of a stretch ceiling

On a loose wall surface, several self-tapping screws must be screwed into one section of the profile, thus increasing the strength of the fastening. As an option to solve this problem, you can strengthen the baguette with corners or focus on it. To prevent condensation between the stationary ceiling and the stretch ceiling, you need to drill holes in the profile, which will serve as ventilation. On curved sections of the wall, it is most convenient to use a plastic baguette, because it not only bends well, but also fits snugly against the wall. If you are not confident in your abilities and are worried that you will not be able to cope with the installation of the profile, then it is better to entrust this matter to professionals. They will do everything smoothly and efficiently, and you don’t have to worry about the fact that the outer corners of the baguette of stretch ceilings will turn out to be sloppy, and the canvas will sag over time. The main thing is not to save on the master and materials, but to give preference to a company that has been providing its goods and services for many years.

How to cut a corner on an indoor and outdoor ceiling plinth using a miter box

Have you decided to install a ceiling plinth (fillet, molding)? Do you want to hide the joints and get a finished look? While doing the work, you may encounter a lot of nuances. To avoid difficulties, you should figure out how to cut a ceiling plinth in the corners of internal and external, what is a miter box and how to make it. This is what we'll do.

Tools

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

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

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

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

Trim the corners

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

Internal slope

Gouging an inside corner is done step by step in a certain order:

First you need to measure the desired length of the plinth on the ceiling.

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

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

Press the workpiece against the far wall of the tool, holding it with your left hand.
The next step is to set the file at a 45 degree angle so that its handle is as close as possible to the left hand. The plinth should be cut without strong pressure on the saw.

Next, you need to cut the reciprocal bar. To do this, the workpiece is installed against the far wall.
We hold her right hand.
We turn the hacksaw at an angle of 45 degrees. In this case, the handle should be turned to the right. After that, you can cut off the plinth.

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

Following this algorithm, you can do the job with millimeter accuracy. And the question of how to trim the inner corner will already be closed.

External slope

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

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

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

Holding the bar with your left hand, turn the handle 45 degrees to the left with a hacksaw and cut off the baseboard.
To saw off the striker, you need to position it closer to the front wall of the fixture, holding it with your right hand. Saw off the skirting board at a 45 degree angle by turning the handle to the right.

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

We make a miter box on our own

Sample

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

first, two clear lines are applied in parallel;
between these lines, a central point is determined and marked on paper;
with the help of a protractor, the necessary angles are drawn, which can be more than 90 degrees.

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

miter box

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

Of the three wooden planks or slats mounted U-shaped boxes. On its walls, grooves are marked and cut out at the desired slopes.
Two boards are knocked together strictly in perpendicular planes. A pattern is applied to the paper in the form of lines with inclinations of 45 degrees for cutting. The workpiece is applied to the corner, pressed against it by hand, as in the case of using a miter box, and the paper template is located on the opposite side. Cutting the fillet is carried out with orientation to the lines drawn on paper. When cutting a ceiling plinth, you can use anything that forms a right angle.

Other Ways to Trim Corners

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

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

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

The intersection point of the drawn contours will mean the mark along which the plinth is cut, forming corner in ceiling molding.
Then you should reattach each plank in turn and mark on them a cut line connecting its two edges.
The plinth is cut along the marked lines, after which its two parts must be joined and attached to the installation site.

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

Types of fillets

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

polyurethane;
polyvinyl chloride;
polystyrene (polystyrene);
tree.

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

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

PVC skirting boards are different favorable price. However, the material is capable of accumulating static electricity.

Polystyrene fillets are resistant to moisture, have good quality and attractive appearance. However, when mechanical influences may break.

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

You can ideally cut the corners of the plinth with your own hands

Now you know how to make a miter box yourself and how to make a clear corner on the ceiling plinth. By following the rules I have described, you can easily solve this problem. If you have any questions - ask them in the comments. A visual algorithm of actions will demonstrate the video in this article.
