How to properly cut a ceiling plinth in the corner

Outside corner

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

In the video in this article, all the nuances are well described:

Inner corner

  • Making the right measurements.
  • After that, we install the plinth strip in the miter box so that this position exactly coincides with the placement on the ceiling.
  • The plinth should be firmly pressed against the opposite wall of the miter box. Hold and press with your left hand.
  • We put a hacksaw at an angle of 45 degrees in a special hole and cut off the part.
  • The adjacent part must be cut in the same way, only in a mirror image, as shown in the photo.
  • When cutting soft materials (PVC, Styrofoam), use a metal hacksaw or a regular utility knife. Then your work will be neat and with smooth edges. For an accurate cut, you need to start cutting it from the front.

    How to properly glue the ceiling plinth. instructions

    The joint between the ceiling and walls often requires additional decoration with decorative elements. Most often, ceiling skirting boards are used for these purposes. Such a simple element allows you to significantly soften the line of the fracture of two surfaces.

    In this article we will talk about how to properly glue the ceiling plinth, as well as how to join it on the inner and outer corners of the walls.

    Ceiling fillets can be made of wood, polyurethane foam, gypsum or foam. Regardless of the type, the sticker of the ceiling plinth is carried out according to the same principle, only the cool composition undergoes changes (read: “Fillet. what is it”).

    The first way is with a miter box

    Professional miter box with a rotary hacksaw For a long time already carpenters have come up with such a special box with slots. a miter box. It is easy to recognize it, among the variety of repair equipment, by its characteristic appearance. This is the most convenient and irreplaceable device in solving the problem that has arisen, how to cut the corners of the ceiling plinth.

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

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

    How to properly glue ceiling plinths in the corners?

    The best way to prepare ceiling fillets for corners is to use a miter box. This is a special stand with markings for cutting skirting boards. The U-shape with deep slots in the side walls allows for cutting at right angles and 45 degrees. The workpiece is placed in a certain position, trimming is carried out with a special saw or hacksaw for metal.

    The position is selected depending on the type of corner: external or internal.

    Getting started:

    • We start from the left side of the outer corner. The lower part on the ceiling should be on top in the miter box. Cutting is carried out as follows:
  • The outer right corner is cut off like this:
  • For the left inner side, we lay the panel with the bottom up, trimming is done in this position:
  • The inner right corner is done like this:
  • The general cutting scheme will simplify the process of preparing the corners. Practice in short pieces before starting work.

    Attach the workpiece to the ceiling. Apply the adhesive mixture to one side of the panel, then to the other. It is recommended to use special mixtures for joints. They are usually sold in cans with a pistol. This solution will not allow the seam to crack at temperature extremes. Skirting boards can expand and contract slightly.

  • Check if the position is correct.
  • Remove excess glue with a spatula and a washcloth (cloth).
  • How to glue the corners of a ceiling plinth without a miter box?

    To trim fillets, you can do without a miter box in two cases: by making a markup on the wall or by drawing a miter box. Choose a method that is more convenient for you.

    Algorithm for “wall” trimming of the plinth:

    • The edge of the skirting board is cut at an angle of 90 degrees, applied to the corner. Draw the fishing line along the contour with a pencil.
    • The first bar is removed, the second is applied. Mark the wall again.
    • Now you have a point of intersection of the lines, you need to transfer it to the skirting boards. We connect this mark with the edge of the element. we get a fishing line for cutting.

    You can make a drawing of the miter box on paper, cardboard or board.

    • Draw 2 parallel mowing lines on the chosen base, use a protractor to set the angles at 45 degrees.
  • The markings will be enough for the work. The workpiece works as follows: a fillet is applied along a parallel mowing line, cutting is carried out at one of the corners.
  • Note that the angle between the walls is not always 90 degrees, respectively, and the trim is not 45 degrees. Before gluing the ceiling plinth in uneven corners, you should use the drawing of the miter box.

    If you made a mistake when joining the corners, the situation can be corrected with the help of special fittings. internal and external corners. The ends of the panels are inserted into the product.

    Fittings can be with decorative trim.

    Cutting and gluing the skirting boards will not take long. The main thing is attentiveness. If the surface is slightly damaged after gluing, glue remains, all these places can be corrected using fine-grained grinding.

    At the end of the work, an effective wall / ceiling transition is obtained.

    In order for the wall covering to be of high quality and durable, all laying rules should be observed. How to properly lay tiles on the wall, we will show in the master class.

    What tools will be needed?

    For ceiling plinths, the following tools may come in handy, depending on the chosen method of work:

    • Saw on wood. Suitable for working with wooden ceiling plinths.
    • Metal sheet. Suitable for other types of skirting boards (foam, plastic, etc.).
    • Miter box. The tool is a chute, which has the shape of an inverted P, where mowing lines are outlined at angles of 45 ° and 90 ° for cutting.
    • Electric miter saw. Can be used instead of a miter box, helps to achieve high cutting accuracy.
    • Electric jigsaw. Easy to operate, with the help of it you can efficiently 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.

    Using fillets

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

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

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

    We cut the corners of the ceiling plinth without a miter box

    How to properly cut a ceiling plinth without a miter box? To work, you will need a well-sharpened pencil, a small piece of plinth, a stationery knife (for polystyrene or polyurethane) or a metal saw (for other materials), a ruler.

    You need to attach the plinth to the corner and draw the line with a pencil along the outer edge, then attach to the other side of the corner and also mark. As a result, a cross will turn out on the ceiling, the center of which will mark the place where the plinths of the ceiling plinth should converge. Place a piece of skirting board where you will glue it. Resting the end against the wall, transfer the desired mark to it. This way you can cut the corners of the skirting board without a miter box.

    How to cut skirting boards using decorative corners

    With the help of them, 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 to them tightly. Cutting them is easy using a clerical knife.

    Making corners using a miter box

    If the walls and corners of the room are even, you can use a miter box for work. In order to cut the corner correctly, the part in which the person will make a gash should be laid inside the miter box, then insert the saw into the guides. This holds the part in place and can be cut at the desired angle. For high-quality cutting of the plinth, it must simultaneously adhere to both surfaces, so it should be pressed against the wall of the miter box. The ceiling plinth is pressed with the side that is closer to you.

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

    Follow the instructions below:

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

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

    How to join skirting boards in the corners

    When a certain part of the plinth is glued and a small distance remains to the corner, so as not to be mistaken with the length, it is necessary to leave a margin. To begin with, you can cut off a piece that will be 10-15 cm longer. Then cut the corner in a convenient way, try it on a dry surface, attach the plank to the ceiling and highlight the place to which it needs to be shortened. Undercutting is performed at an angle of 90 °.

    Next, you need to correctly join the corners. The made ceiling moldings are attached at an angle of 38-45 °, so the classic 45 ° is not always suitable at the joints. In various cases, the cut edges do not join and leave gaps. For this reason, after the initial trimming of the corners, it is necessary to carry out a “dry” and most accurate joining of the baguettes directly to the ceiling. Especially have to tinker with wood and plastic materials.

    Having completed the rough joining of the skirting boards, glue or screw the fillets to the walls and ceiling, then, if necessary, use a putty and seal the seams at the end.

    Important points on how to cut a ceiling plinth in the corners

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

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

    The first way is with a miter box

    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 represents 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 on them is slightly different.

    If necessary, you can make a miter box with your own hands. To do this, you will 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.

    Outside corners

    It happens that the room has not only internal, but also external corners, which also need to be pasted over with a plinth (see photo). How to do it? There are several ways here as well. The easiest way, as with the inner corners, is to cut them with a miter box. The outer joints must be cut so that the side that will be glued to the ceiling is on the surface of the miter box, and the side pressed against the wall is facing the wall of the fixture.

    As with the inside corners, you can also use in-place markings, that is, draw the line on the ceiling. Here, the technology is exactly the same as that used for the inner corners.

    You can use the markings on the wall by attaching a workpiece and drawing a fishing line along its lower edge (see photo).

    If the outer corner turns out to be too rounded, you can finish the joint with a knife.

    Trimming the ceiling plinth. Outside and inside corners

    To the point where they converge, the line is drawn directly along the future part of the connection. From the point on the ceiling to the second one. The resulting marking will be the line along which you need to saw off or cut off the connecting parts. Using these techniques, you no longer need to wonder how to cut the corners of the ceiling plinth.

    other methods

    With a good eye and accuracy of hand action, you can use a homemade template that resembles an imitation of a miter box. To do this, take a thin board or thick plywood and draw a layout in the form of a horizontal rectangle. Using a protractor, mark 45 ° on the right and left sides of the rectangle. Draw mowing lines connecting opposite edges. You can now cut off the ceiling plinth using this layout. The actions are simple and similar to the description above in the first option. Only the ceiling parts should not be inserted, but placed on the drawing and the hacksaw should be combined with the layout of the layout.

    Special accessories for docking

    Today it is impossible to imagine the interior of a residential building or apartment without ceiling plinths. The skirting board covers the irregularities of the suspended ceiling or wallpaper, cracks and imperfections in the walls, and gives the interior completeness. But how to make the skirting board perfectly fit in the most important place. in the corner? There are several ways.

    Thus, cutting corners when gluing baseboards is one of the most difficult and responsible procedures for which it is advisable to use a special device. a miter box. which allows you to cut the baseboard at an angle of 45 degrees. If the angle between the walls is not straight, you have to use manual marking. Cutting tools depend on the material of the baseboard.

    Using factory corners. an alternative to cutting and sawing

    PVC ceiling molding corners

    The disadvantage of corner pieces is that they are actually and visually larger than the baseboard, which will make the corner noticeable. This can ruin the look of the room. It is also inconvenient to use corners where the walls do not join strictly at an angle of ninety degrees. But most of the time they look great.

    Outside corner

    • Measure the length of the plinth from the nearest wall to the outer corner, leave the fishing 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 until a perfect fit.

    Checking the smooth docking

    All the nuances are well described in the video:

    What tools can be used?

    The feasibility of using certain tools is associated with the materials from which the skirting board will be made.

    Tab. 1. Varieties of materials and features of their use.

    Type of material Material properties, requirements Tool
    Polyvinyl chloride (PVC)PVC skirting boards are distinguished by the fact that they are easily damaged when pressed and no longer restore their former appearance, since they are devoid of elasticity. Therefore, such skirting boards cannot be pressed when cutting.Cut with a construction knife or a hacksaw for metal. A blade or a sharpened kitchen knife will also work.
    StyrofoamFoam plinth is also not very durable, but better than PVC counterparts. Easily crumbles.The same tools can be used as for PVC
    WoodStronger and more aesthetically pleasing than their polymer counterparts, but expensive.It is best to cut the tree with a hacksaw, you can use metal, although this way you run the risk of hammering the teeth of the blade with wood sawdust. A hacksaw with fine teeth is best.

    How to dock the ceiling plinth in the corners: step by step instructions

    How to fit the ceiling plinth in the corners is one of the main questions that are asked when repairing ceilings. When installing skirting boards, difficulties arise when it is necessary to adjust the joints of individual elements. And, if on straight sections it comes out to glue the fillet the first time, then you have to tinker with the corners. Therefore, a reasonable question arises, how to dock the ceiling plinths in the corners so that the connections are invisible.

    How to properly join ceiling skirting boards: getting ready to work

    For work you will need:

    • plinth;
    • glue;
    • stationery knife;
    • hacksaw for metal with small teeth;
    • ruler;
    • roulette;
    • pencil;
    • miter box;
    • sealant;
    • dry clean cloth.

    How to make a miter box with your own hands

    As for the miter box, in the absence of one, it is easy to make the instrument yourself. Take three sanded boards and connect with self-tapping screws in the shape of the letter “P”. Now make the cuts so that the skirting board is easy to cut at the desired angle. Usually, the middle line is cut at an angle of 90 °, and the outer ones. 45 °. The cut should reach the point where the side walls of the miter box are attached to the lower base. The side walls are made of both wood and aluminum. Metal tools will last longer.

    Before starting work, the ceiling surface and walls at the place where the skirting boards are attached must be prepared. They are cleaned of dust, old finishes, leveled with putty and primed. Any water-based paint that improves the adhesion properties of the glue is used as a primer.

    On a note! Fillets are best fixed to the wall surface, not wallpaper. So the skirting boards will hold more securely.

    Choose glue on an acrylic or silicone base. Alternatively, you can use putty, then, in addition to gluing the frieze, it will be possible to eliminate irregularities on the surface of the wall. Glue is used to fix the baguette to the wallpaper, the putty to the walls.

    Ceiling plinth adhesive

    “Liquid nails” cannot be used for plastic fillets, since they contain solvents that deform the skirting board.

    If you wish, you can make your own glue. To do this, mix the putty and PVA glue in a 1: 1 ratio, let the substance sit for 5-10 minutes. The solution must be worked out in 2 hours, as it hardens quickly. Styrofoam, gypsum and wooden fillets are fixed on such glue.

    To make it easier to work, beat off the control line with a paint cord under the ceiling.

    With strong irregularities and distortions of the walls, the skirting board will only highlight imperfections. However, this rule also works in the opposite direction. Even with uneven corners, the situation can be corrected with the help of a properly glued ceiling frieze. The main thing is to follow the sequence when working. Attach the first element from the corner closest to the entrance to the room. During installation, try to form as few joints as possible.

    How to dock the ceiling plinth in the corners: important nuances

    Docking fillets in the corners is carried out in one of two ways:

    • in the inner corners;
    • in the outer corners.

    As for the internal corners, they are in any room, their value is 90 °, external (270 °) are less common.

    Features of trimming moldings in the corners are identical:

    • when working with a miter box, the side of the frieze that is pressed against the wall of the tool when cutting the corners with the side part will be attached to the wall surface, to the base of the miter box. mounted to the ceiling;
    • for internal corners, the lower side of the plinth protrudes above the upper, for external corners. vice versa;
    • measure the corners in the room with a protractor. If the value is 90 °, then cut the edges of the baguette at 45 ° angles. For non-standard angles, halve the measured value. Then the frieze located on the left side of the corner will have a right cut, on the right side. left.

    To cut the skirting board, fix the molding in the miter box to prevent slipping. After making the cut, join the two pieces together to check the result. Flaws are removed with a clerical knife or file.

    If it did not work out perfectly to fit the fillets

    It may well be that the first time not everything will go as smoothly as you would like. In this case, it is better that there is a gap between the adjacent elements of the baseboards, which can be masked with silicone sealant. To do this, carefully fill the gap with the compound, smooth out the sealant with your fingers, remove the excess mass with a wet cloth.

    If the cut turned out to be less than necessary, and when trying to dock the skirting boards one of them “goes” to the side, take a clerical knife and cut the cut, or sand with fine-grained sandpaper.

    How to join ceiling skirting boards in straight sections

    After the corners are finished, the easiest part of the job remains. gluing the friezes on flat areas. If the edges of the planks are uneven, trim the baguette at right angles on both sides.

    When the plinth is ready, coat the segment with glue on the back side, attach it to the end corner strip, press. Glue the next part from a different corner.

    At the end, a piece of plinth is installed in the middle. There will be no questions with this part of the work. To get a perfect fit, sand the cut sides of the frieze with sandpaper or a file. When you attach the fillet to the wall, press it with the edge of your palm, then the shape of the baguette will not suffer. Remove excess adhesive with a cloth.

    When the skirting board is glued, inspect the result again. The resulting cracks at the joints are putty or sealed with a sealant.

    You can leave the baguettes as they are, or paint to match the rest of the finish. Painting is carried out both before attaching the skirting boards to the wall, and after installing them.

    How to join the corners of ceiling plinths: external and non-standard

    Despite the fact that outer corners are less common in rooms, knowing how to join ceiling skirting boards in them will not hurt. To cut the fillet, proceed as follows:

    • press the friezes crosswise against the wall. This will tell you where to start and end the cut;
    • outline the line along which you will cut the frieze;
    • cut the baguettes along this mowing line, check the docking by aligning the skirting boards in the corner;
    • the cut should have straight edges. If defects are obtained, trim the cutting line with a knife or file with a file.

    Sometimes even craftsmen have to face difficulties when fitting skirting boards. For example, if the room has non-standard corners. In this case, the skirting boards are cut into small fragments (5-10 cm), which are alternately docked with each other and glued to the wall. In order not to get confused in the sequence, the order of each element is outlined with a simple pencil on the reverse side. After the parts are glued, remove excess glue or putty, continue to work further.

    Preparation of skirting boards for work is carried out before applying the markings.

    How to join ceiling skirting boards and what you need to know about fillets

    Skirting board is a decorative element used in the interior to indicate a smooth transition between the ceiling and walls. If a stretch ceiling is installed in the room, the fillet will hide the gaps formed during the work. Often the evenness of walls and corners leaves much to be desired, therefore, ceiling baguettes are also used to mask such defects.

    Another task that designers assign to skirting boards is to act as a kind of niche for mounting decorative lighting. This idea has been used in interior decoration for several years. The light from the tape located on the inner side of the skirting board gives a soft diffused glow, filling the room with a cozy and comfortable atmosphere, creating the effect of a decorative ceiling floating (floating stretch ceilings).

    Ceiling lighting around the perimeter

    As a material for the manufacture of fillets, polyurethane or polystyrene is used. A special extrusion method makes it possible to obtain light and flexible friezes, with the help of which it will be possible to bypass uneven walls. Baguettes are also made from plaster or wood. In this case, the surface of the decorative element is completely smooth, with patterns or deep relief. The most common type is white friezes, which can be painted to match the color of the interior.

    The figure shows fillets with relief

    Decorative skirting board is combined with plastic panels, foam tiles, textured wallpaper. The ceiling gets an interesting look when products are combined with stucco elements.

    Bonding fillets. the finishing stage of the ceiling decoration. Baguettes are produced with a standard length of 2 m. Therefore, during the work, you will have to adjust the parts for joining in straight sections and in the corners of the room. Corner docking is the most difficult stage.
