Details on how to cut the plinth in the corner and dock it. How to saw down a ceiling plinth: methods for cutting corners using a miter box, a drawing on the table and markings on the ceiling How to file a ceiling plinth

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 of profile, a special result is obtained. 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

1. 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.
2. 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.
3. 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

1. 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.
2. To make the outer corners of the baguette of stretch ceilings, you need to attach the profile to the wall, and draw at a distance of 2 cm from the corner straight line, 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.
3. 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.
4. 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. Gash inner corner for 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.

This is where the question arises: how to cut a corner ceiling plinth. The same problem appears when forming a frame for the floor. Therefore, in this article we will tell you how to cut the skirting board in the corners correctly.

Knowing the basic secrets and nuances of cutting this product, you will quickly and efficiently carry out its installation, give the room a complete look, creating a harmonious frame for the finished surfaces.

Features of cutting the catch of the ceiling plinth

Installing a baguette on the ceiling, at first glance, is very simple - most of them are attached to glue. But most milestone are preparatory work: cutting planks and corner pieces for a ceiling plinth.

To make the room beautifully framed and not have to redo the repair, you should know how to make baguette corners. Having mastered the knowledge of how to cut the corner of the ceiling plinth, you will not only save Construction Materials and time for product installation, but also funds that could be spent on a good craftsman.

Forming and cutting the inner corner of the ceiling baguette

When edging surfaces, the question arises: how to join the corners of the ceiling plinth. They can be:

• internal;
• external.

Docking ceiling fillets - external and internal (outer) corners

Let's take a closer look at how to cut the corners of a ceiling plinth. Normal rectangular room, without protrusions and columns, has 4 corners, in which the internal joint of the baguettes is carried out.

Therefore, before gluing them, markings are made, during which it is necessary to measure the perimeter of the ceiling, outline the junctions and joining parts.

Cut places are marked on baguettes

How to saw down a ceiling plinth to form an internal corner? First, the angle between the ceiling and the wall is checked. If the surfaces are even, then it should be 90 degrees. In this case, the corner elements are cut at an angle of 45 degrees. To cut them, you can use a clerical knife (styrofoam molding, polyurethane, a hacksaw, but it is most convenient to use a special carpentry tool - a miter box for a ceiling plinth (groove with slots) and grinding.

Then the first plinth is evenly inserted into the miter box, fixed, and cut on the right side at an angle of 45 degrees.

Cutting skirting board at an angle

Before gluing the baguettes, the second corner piece is cut in the same way, making an incision on the opposite side.

Trimmed parts are tried on, checking the tightness of the connection

After cutting all the details, you can proceed to the installation of the plinth on the ceiling.

Cutting and joining ceiling moldings at external corners

If there is a ceiling in the room complex shape, or walls with protrusions, external corners are formed. How to cut down the ceiling plinth in this case? For these purposes, a miter box is also used.

How to properly cut a ceiling plinth for shaping outer corner? First, the fillet is inserted into the tool with the side that is closer to you. The edge that will adjoin the ceiling should be located at the bottom of the miter box. Next is cutting at an angle of 45 degrees.

Scheme - how to cut the corner of the ceiling plinth to form an external corner

Before you make the corner of the ceiling plinth, you should bring the baguettes together and check the evenness of their connection. The two cut pieces are put together. If there are no gaps, and the edges of the products adjoin tightly, the cutting is carried out correctly.

An example of how to correctly match the details of the edging in the corner

If you don't have special device for cutting baguettes, you can use a square, or make patterns out of cardboard. Any unevenness can be carefully trimmed with a clerical knife, and if there are small recesses, they should be filled with sealant.

Many are concerned about the question: how to connect the skirting boards if the walls are uneven? In this case, the first fillet can be cut on the miter box, and the second can be adjusted to it manually until the cuts match.

With help plastic corners you can neatly arrange the joints

Features of working with various materials

If you install gypsum ceiling fillets, they don't cut like regular ones. They need to be sawn from the decorative side. In this case, chips will remain on the back of the product. If burlap is attached to the back of the stucco, it should be cut with a sharp knife. Next, with a special hacksaw, fillets are cut at an angle of 45 degrees to form external and internal corners.

Installation of a gypsum baguette, joining two trimmed parts

How to cover the joints between the fillets? The seams are sealed with gypsum or putty, and after drying, all irregularities are polished.

Features of the formation of the catch of the floor edging

The plinth for framing the floor not only completes the look, but also hides the joint along the perimeter of the wall, improves the sound insulation in the room. The perception of the room as a whole will depend on how correctly and accurately you manage to join the planks in the corners.

How to cut a skirting board in a corner? Required tools:

• tape measure and pencil;
• miter box;
• hacksaw or jigsaw for cutting the product;
• sandpaper;
• sealant or putty.

Step-by-step instructions for forming corners and joints of floor planks

First, the marking and calculation of the necessary edging material is carried out. In order to get a neat angle, parts of the joined elements should be cut off at an angle of 45 degrees. To do this, the part is installed in a miter box, fixed, and cut off on one side with a hacksaw or jigsaw.

Similarly, saw the opposite end of the second plank

To connect the skirting boards along the perimeter of the wall, they are cut at an angle of 90 degrees. The cut edges of polyurethane products are processed sandpaper, for their complete alignment and better adhesion.

Docking two planks cut at right angles

Before installing the skirting boards, first check the accuracy of their joining. Then glue the first part, dock with it the second, cut at an angle of 90 degrees.

A special PVC connector is used to mask the joints

During installation, you can cut out part of the edging in order to lay communications in it. It can be sockets for sockets, switches.

Socket box embedded in PVC skirting board

Corners, internal and external, are formed in the same way as when installing ceiling moldings. Cutting baguettes is carried out in a similar way.

In order to close the joints of cut PVC products, there are special decorative corners.

In order to cut and install baguettes quickly and efficiently, you should plan all the work in advance and prepare necessary materials and tools.

After taking measurements, write down the length of each wall, adding 50 mm to it on each side (for trimming the corners of the plinth). Try to cut the planks so that there are as few leftovers as possible. In order to save material, cut it end-to-end.

How to easily cut baguettes

To securely fix the workpiece for its further cutting, you can use the tselaga. This is a special bench clamp, to the back wall of which a bar with a groove is attached. This furrow is made at an angle of 45 degrees. Therefore, it can be used as a deep template for cutting skirting boards.

To do this, take a bar, which is slightly higher in thickness. required thickness. To cut the plank most precisely, use a special saw for precise sawing. Use it to cut grooves in the template at the desired angle.

Outcome

Beautiful ceiling and floor plinths complete the interior of the room. They not only decorate the room, but also protect surfaces from damage. Skirting boards can be made independently (wooden), or you can buy finished products. In order for such a frame to look beautiful, it is necessary to correctly cut the details of the edging during its installation. Following simple recommendations, you can cut baguettes and form corners yourself.

Installation of fillets (or) can be a real problem even for those who already have experience in repair and finishing work, because the main task is rooms so that there are no gaps and cracks. In addition, quite a few apartments built in Soviet times, differ in perfectly even walls and corners, which at times complicates the task. The question arises: how to file the baseboard correctly and make an even, neat corner at home? Let's look at a few ways.

The ceiling plinth or fillet serves as the final element in the interior design of the room.

It is worth noting that the ceiling plinth, or as it is also called, " ceiling baguette» made from different materials, so not all options will be equally effective for different types skirting boards.

The main goal is to correctly cut the "left" and "right" fillets. The connection must be tight, excluding the formation of gaps. Using a foam ceiling baguette, the deviation is easy to correct due to the softness of the material. If you are dealing with plastic or wood, then it is worth trying. In any case, you need to start from the corner, so you will have the opportunity to correct inaccuracies if necessary.

With an electric saw

The miter saw cuts at an angle with high precision.

For the perfect cutting of the ceiling plinth, it is best to use an electric miter saw, where you can set any direction and saw off the desired slope as accurately and accurately as possible. It does not require much effort. You just need to set the desired parameters and lower the saw blade onto the surface to be cut, be it wood or plastic. However, you can also cut down the ceiling plinth with the help of cheaper tools.

With the help of a miter box and a hacksaw

First of all, when calculating the desired direction for the cut, you need to remember one feature: unlike the usual skirting board, the ceiling skirting board is installed on the base at a certain angle, usually 38-45 °, so it will be very difficult to accurately measure the “correct” 45 °.

Therefore, at , it must be kept in the position in which it will be installed on the surface.

A miter box is a device for cutting a skirting board at a certain angle.

This can be done using a miter box - a small tray made of plastic or wood with slots for a hacksaw at angles of 90 ° and 45 °. A miter box can be bought at almost any hardware store. We will also need a fine-toothed wood saw or, even better, a metal saw. However, when using hand saws, you need to be careful - there is always a risk of spoiling the material. If you are dealing with the most common types of ceiling moldings - foam, then a wallpaper knife with a new sharp blade will do.

The main task is to determine how the cutting lines will pass on the joined "left" and "right" parts of the skirting boards. If the corner is uneven or non-standard, you need to find its middle - there should be a joining line.

The plinth in the miter box must be positioned as it will be glued to the wall: hold the top (a) of the element, and press the bottom edge (b) against the wall of the miter box.

So, for starters, you need to attach a straight fillet to the corner of the room and visually determine the cut line (if the corner in your room is even, that is, about 90 °). Then we put it in the miter box and substitute it under the desired hole for cutting. The fillet must be placed in the miter box so that it lies at the angle at which it will be attached to the wall, that is, in the corner. Now it remains only to saw off or cut with a knife. If you use a hacksaw for metal - make light movements, avoiding pressure, this will lead to breaks or chips (for plastic). In order not to get confused in the materials, put a mark on inside ceiling baguette with a marker or pencil. Please note that the cutting direction will be different for the outer and inner corners, so it is recommended to mark directly on the miter box: sign the holes for the “right” and “left” fillets of the outer and inner corners.

Using improvised means

The drawing on the table imitates a miter box. However, instead of pressing the plinth against the side, as in a miter box, we expose it along the line. For convenience, you can attach some rectangular object to the line to make a side.

If you could not get a miter box, you can try to make it yourself from improvised means. In the end, you need to knock down two boards, because the main thing is to securely hold the baseboard in the corner when you cut it. And in order to make a cut evenly and correctly, we need a stencil. You can make it from thick cardboard so that it exactly repeats the angle between the walls. If the walls and ceiling are uneven, the corner is divided in half - there the cut line will pass. Place the corner you made from the boards on the stencil so that the edge of the corner is exactly above the stencil corner. Now you need to insert the (“left”) fillet into it and carefully cut, focusing on the contours of the stencil. To cut the "right" you need to rearrange the corner to the appropriate side. You can think of other devices for cutting right angle for the ceiling plinth, using the same principle.

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 on how to cut a plinth in the corners, how to properly join the planks, how to cut and connect the corner parts of narrow and wide, curly 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 building corner if they are straight, then you can cut the corners so that they fit snugly, without a gap, in the corner with the help of a miter box.

The ceiling plinth cutting miter box is a simple carpentry cutting tool, consisting of a tray with a rim to hold the plank 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

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. It is known from the school course 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 for making cuts.

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 installation ceiling profiles. The only difference is that when cutting on a miter box, the side that will rest on the flooring should adjoin the side, and the leg that will be adjacent to the wall should lie on the base of the device.

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 embedding the outer corner of the floor plinth is 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 in the traditional way is 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 you can use a wax pencil, or a special wood putty. After the repair compound dries, a decorative finishing layer is applied on top.

Before cutting 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 with 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.

There are more than enough tips on how to cut a skirting board at 45 degrees on the net, the only bad thing is that most of them are given by people who have never done this. Next, from a practical point of view, I will tell you how to cut skirting boards at the corners with your own hands in 3 options, and you will learn how to traditional ways, and about folk universal recipes.

The science of how to properly cut ceiling moldings in corners is not as complicated as it might seem.

A few words about tools and materials

Floor skirting boards are now made of wood or polyvinyl chloride (PVC), in other words, plastic. Ceiling fillets have a slightly longer list:

The range of ceiling plinths is much wider than that of the floor direction.

1. Polyurethane - these skirting boards have good elasticity and can bend around radial and other curved surfaces, but in any case, they need to be cut at clear angles;
2. Foam - the easiest a budget option, the price of foam skirting boards is low and they are very easy to cut;
3. PVC - the principle is the same as for floor skirting boards, but the lineup much wider;
4. Wooden - similar to the floor, only there are still wide models;
5. Gypsum - with the advent of polyurethane and foam, gypsum ceiling fillets faded into the background, firstly, they are heavy, and secondly, fragile. But in fairness, it's worth mentioning them.

Since it is impossible to properly cut the ceiling plinth and its floor counterpart without a good tool, we will dwell on this issue in a little more detail.

The best, almost ideal tool for cutting any skirting boards and not only is a miter saw with a rotary bed. The high-speed disc makes smooth and precise cuts, and the bed in these units rotates to any angle. The only problem is the serious cost of this tool.

A miter saw is almost the perfect tool for cutting skirting boards and more.

It is believed that one of the best hand tools for accurately cutting small bars is a backsaw. In principle, this is true, but I’ll tell you honestly, a really high-quality saw, even with the current assortment, is not easy to find. If you still decide to buy such a tool, then take a saw with a fine tooth.

Theoretically, foam and polyurethane can be cut with any sharp and durable knife. But at the same time, you need to have a steady hand and at least a little experience in cutting foam. Plus, cutting wide fillets with a knife is very problematic.

Without experience, making a clear cut with a knife is very problematic.

Personally, in the absence of trimming, I use only a hacksaw for metal. It is suitable for cutting absolutely any material, from foam to wood. By the way, the question is often asked how to cut a plastic plinth for the floor, and so - take a hacksaw for metal and you definitely can’t go wrong.

For cutting skirting boards, a hacksaw is considered one of the best tools.

Three ways to cut skirting boards

For floor and ceiling plinths, the cutting instructions are almost the same. But if on the floor a curved corner can be covered with something, then on the ceiling this is already a problem, so we will pay more attention to how to cut ceiling skirting boards.

Method number 1. Classic miter box

The classic miter box is a U-shaped bed with slots in the opposite sides. A part of a suitable size is inserted into this bed and sawn off with a hacksaw through the slots in the sides. The idea is not new, the tool is already several hundred years old, but, despite the simplicity, not everyone knows how to properly cut the corner of the ceiling plinth using such a miter box.

Not everyone knows how to cut a ceiling plinth in a corner using a classic miter box.

Tip: when trimming, ceiling plinths are applied to the side of the miter box that is closer to you, and floor plinths on the contrary, you need to apply to the side of the instrument farthest from you. This is not a dogma, but it is much easier to work this way.

It is easier to work with floor plinths, since the miter box lies on a horizontal plane, it is easier for you to navigate in the position of the plinth. People most often make mistakes when trimming a ceiling fillet; they are simply incorrectly put into the tool. There is a simple but important rule here.

Important: the edge of the ceiling fillet, which touches the wall, should be directed to the upper edge of the side of the miter box, and that part of the plinth that borders the ceiling is placed on the bottom of the miter box.

The corner, as you know, has 2 sides, so, in order to be less mistaken, accustom yourself to putting the bar that will be mounted on the right side of the corner into the miter box on the right, and put the bar that is attached to the left into the miter box on the left. Details about the intricacies of using a classic miter box are described in the video in this article.

In addition to the classic U-shaped miter box, there are two more types of similar structures - this is a professional and rotary tool. As for the professional version, only masters use it. The device is quite bulky, but it rotates at any angle and has a hacksaw that can be fixed in the desired position.

Professional miter box with the ability to fix a hacksaw and parts.

The swivel device can be safely called a "pocket" miter box. Of the advantages here, only the possibility of a clear fixation of the angle of rotation of the bar. On the one hand, it’s easy for them to work - I set the corner, attached it to the plinth and cut it off. But on the other hand, you need to get used to such a tool, if you do not have experience with a hacksaw, then you should not take a rotary miter box.

Tip: when choosing a classic U-shaped miter box, first of all, do not take Chinese products. And secondly, try to buy models with the ability to rigidly fix the part inside, one of these models is shown in the photo below.

A miter box with the ability to fix the part inside is much more convenient to work with.

Method number 2. Trimming according to the template

Most often, both ceiling and floor skirting boards need to be cut at 45º. If there is no specialized tool nearby, then an impromptu miter box can be drawn on a notebook sheet. From the school geometry course, we know that the diagonal of any square with respect to the base has an angle of inclination of 45º.

Next, you need to draw a square and draw 2 diagonals in it - these will be the desired 45º. You just have to correctly attach the plinth to the leaf and mark. True, in order to cut the plinth evenly without guides, you need a good eye and a faithful hand.

Method number 3. Applied universal

A 45º cut is a common option, but what if you need a different angle and only have a hacksaw and a pencil? It turns out that there is a very simple way out of this situation. Plus, this method is universal, it is suitable for both external and internal corners.

Moreover, I can assure you that those angles that visually appear to be straight, in fact, have deviations of a couple of degrees. As a result, you buy good tool, cut off clearly 45º, and when docking, the gap between the baseboards “crawls out”. Here this problem disappears. And then, using an example, we will consider how to cut the ceiling plinth in the inner corner.

Illustrations	Recommendations
	Stage 1. Take a fillet, apply it on one side of the corner and use it to draw 2 lines, along the wall and along the ceiling. Tip: to make the lines inconspicuous, they can be drawn not with a pencil, but, for example, with a nail or a knife edge.
	Stage 2. Do the same on the adjacent side of the corner.
	Stage 3. If you draw a diagonal from the intersection of the lines on the ceiling to the inner corner, then you will get the desired cutting line.
	Stage 4. Then take the tool and cut according to the finished markup. If you normally own a hacksaw, then the skirting boards should converge perfectly.
	. As I already mentioned, exactly the same technology can be used to trim the outer corner.

Important nuances

If you tried as best you could, but a small gap at the junction nevertheless “crawled out”, do not be discouraged. In wooden fillets, such a gap is easily smeared furniture wax. To cover the gap on the baseboards made of polyurethane, foam, plastic or gypsum, putty is perfect. Naturally, the color of the composition must match the color of the baseboard.

All cracks in the area of ​​\u200b\u200bceiling fillets are sealed with putty.

Wide ceiling fillets are certainly beautiful, but they can only be mounted on ideal smooth walls. If the plane of the wall in relation to the ceiling is a wave, then it is better to buy narrow polyurethane fillets, they are elastic and will smooth out this drawback.

Most of the questions arise about how to cut the wallpaper under the ceiling plinth. There is nothing complicated here: the wallpaper is glued with a slight overlap on the plinth, and when the wall is completely glued, take a large spatula, put it in a corner and cut off the excess with a knife.

But keep in mind - neither a knife nor a spatula can be torn off the wall until you have passed the entire plane. That is, they put a spatula from the corner, cut off the wallpaper along the length of the blade, and then without lifting the blade from the wall, move and cut until you reach the next corner.

Conclusion

All three methods I have described work, the choice depends on what tool you have available and what your professional skills are. If after watching the video you still have questions, welcome to the comments, I will help as much as I can.

If you are not confident in your abilities, then for both floor and ceiling plinths there are docking elements that allow you to do without trimming.
