How to properly cut the inner corner of the ceiling plinth

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.

    Method two. no additional tools

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

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

    Do the same with the adjacent part on the other side.

    The end result is an even 45 degree angle when you draw the line from the point of intersection to the edge of the part. This method of how to cut a skirting board is available to everyone, without the presence of special tools.

    Cutting ceiling strips when using corner elements (special connectors) is also usually done in a miter box. How to cut the planks in this case? It’s very simple. the cutting is done at right angles. If there is no tray, you can use a regular protractor or square. Corner elements (photo):

    When using corner elements, the strips are cut at right angles.

    Trim ceiling plinth

    Ceiling skirting boards are made from a wide variety of materials. foam, polyurethane foam. plastic, wood. To trim them, the tools available in every home can be used. Styrofoam strips are cut with scissors or a knife. The wooden plinth is cut with a hacksaw for wood. How to cut a plastic skirting board is also not a question. You can saw it with an ordinary hacksaw for metal.

    How to properly trim a floor plinth

    The skirting boards can be made of PVC. polyurethane. wood or fibreboard. As in the case of the ceiling plinth, they need to be cut, depending on the material, with an ordinary hacksaw (wooden) or a hacksaw for metal (plastic).

    Now you know how to saw down the ceiling plinth. Next, let’s see how the floor trimming and trimming is done. How to use the miter box in this case? When trimming the floor plinth, the procedure is approximately the same as when trimming the ceiling. For the inner corner:

    • We take the first strip and put it in the tray from right to left so that it lies in it just like on the floor. We lean it against the far wall of the instrument as against a wall;

    The strip is inserted into the tray and pressed firmly

    • We trim the unnecessary piece from the left end at an angle through hole 1 (picture below);
    • Insert the second strip from left to right in exactly the same position and cut from the right end through hole 2.

    How to trim a skirting board in a corner if it is external:

    • Insert the first strip into the tray in the same way as for the inner corner (from right to left);
    • We cut it from the left end through hole 2;
    • Insert the second plank from left to right and cut its right end through slot 1.

    How to cut a ceiling plinth for outside and inside corners

    Tip: The end at an angle of 45g should be done not only in order to cut the elements in the corners, but also for making joints on the wall itself. In this case, the connections will not be as noticeable.

    Thus, we have examined in the most detailed way how to cut a plinth in the corners. This procedure is not as complicated as it might seem at first glance. By starting trimming in a miter box or by imitating it, you will see for yourself.

    Skirting materials and cutting methods

    First of all, let’s try to determine what the fillet can be made of, and what specific material is better to cut.

    On sale today you can find products made of polystyrene (polyvinyl chloride), wood, expanded polystyrene and polyurethane.

    Perhaps one of the cheapest skirting boards is made of polystyrene, which is a fragile, soft and brittle material.

    Even the fingers of the hands can leave dents on them, wrinkles and defects are easily formed on them. It is quite difficult to trim the corner of the PVC-based skirting board nicely and evenly.

    For an inexperienced craftsman, a large amount of purchased material can go to waste for this very reason. Also, this polymer has high electrostatic properties, which explains its ability to collect dust.

    It is most convenient to cut such a plinth with a hacksaw or a sharp construction knife.

    Products made from expanded polystyrene are also inexpensive, although this material is a more durable analogue of traditional foam.

    Can also be cut with a sharp tool.

    Extruded expanded polystyrene

    Extruded polystyrene skirting boards are slightly more expensive, they are somewhat denser and more difficult to cut. But they crumble and break much less.

    Therefore, cutting them is more convenient and easier. For this purpose, it is convenient to use a hacksaw or a sharp knife.

    Polyurethane ceiling skirting boards are currently perhaps one of the most expensive.

    But they justify their cost: moisture resistant, quite strong and dense, quite elastic.

    The skirting above the stove may deform and even crackle slightly.

    They are perfectly cut with a special knife without forming crumbs. But these products are very sensitive to temperature extremes.

    Wooden skirting boards for the ceiling are quite heavy and dense products, solid and durable.

    They lend themselves well to processing with a special fine-toothed hacksaw. You can also use a reliable metal blade. So how to cut the ceiling plinth correctly?

    How to cut a ceiling plinth correctly

    Products that mask gaps are fixed so that they fit snugly both to the wall and to the ceiling. The element has a special configuration, but in order to join its fragments, you must first cut the material

    Skirting boards are not cut at 90, but at 45 degrees. This solution then makes it possible to correctly align the baguette both on the outside and on the inside. You can purchase models with a ready-made cut of this type. In this case, the user only has to cut the elements at right angles. But the model is more expensive and does not completely exclude preparatory work.

    In practice, cutting off a 45 degree skirting board is quite easy. Most often, a special device is used for this. a miter box, however, you can do with other means.

    Factory ready corners

    Note that every master has the opportunity not to pore over precise cutting and fitting corners.

    It is enough to measure the required length of the workpiece and cut it at right angles.

    All defects and flaws will be hidden by this special element. But it is not always possible to use such a convenient method, since the standard dimensions of such factory corners can differ markedly from the size of the plinth itself.

    Such angles will stand out for their disproportion, and it will not look very neat. But if the design of the room and the size of the blanks allow you to use this method, then you should not neglect it.

    For those who have to use one of the methods of trimming the ceiling plinth, the following tips will come in handy.

    Ceiling plinth. fillet

    To do this correctly, it is important to strictly follow the existing recommendations and rules for finishing work. And then the result will please you.

    In order to hang the ceiling plinth, even inexperienced repairmen have no difficulty. They are worried about something completely different: how to cut the ceiling plinth correctly? In fact, almost every room, no matter how intricate it may be, is equipped with corners.

    And in these inner corners, the individual elements of the skirting board should be nicely and evenly joined. And in rooms of a particularly complex configuration, you will have to be smart about the outer corners. Let’s try to figure out how to be in each of these situations, and how to cut the desired part using the available tools.

    How to make a miter box for a ceiling plinth with your own hands

    If there is no such useful device as a miter box, you can replace it or make it yourself.

    In simple cases, for example, for cutting foam plastic, ordinary cardboard or a sheet of thick paper plays the role of a miter box. 2 parallel segments are laid on it and the planned cut points are marked with the help of a protractor. Then they simply attach a piece of the product and cut it off using cardboard as a template.

    If the material is wide, hollow inside, or made of such a strong material as wood, it is impossible to do without a miter box or its equivalent. Then do this.

    • A template is made on cardboard or thick paper.
    • Then, corners for the ceiling plinth are made from any suitable material. from two strips, for example. The material is inserted into the element as in a miter box.
    • Then the device is placed over the stencil so that the end of the plinth is above the pattern. A profile is inserted into the miter box substitute and cut with a knife or saw according to the mark.

    At the same time, the knife blade rests only on a homemade product, so you need to be careful when working.

    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.
    Styrofoam Foam plinth is also not very durable, but better than PVC counterparts. Easily crumbles. The same tools can be used as for PVC
    Wood Stronger 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.

    What is it made of and what is it called

    The very first skirting boards on the ceiling were made of plaster. They were cast in special molds and then installed on the ceiling with mortar. Such figured ornaments were called fillets. Today, you can rarely see them: they are expensive, and outwardly they are almost indistinguishable from the cheaper options. And the name is almost lost.

    The most popular ceiling skirting boards are made of polyurethane or polystyrene. They are inexpensive, look great, are easy to install, have a wide range of profiles and patterns. The width can be from 5 mm to 250 mm. They are used in almost any room, decorated in any style. An exception is wooden houses with a corresponding interior. Wooden products are most often used here. the style dictates its conditions.

    There is also a similar plastic finish. It is mainly installed in bathrooms. But even in damp rooms, you can safely mount polyurethane strips. they are not afraid of damp.

    You need to cut the ceiling plinth in the corners of any material in one of the ways described below. The only exception is plastic skirting boards: you can arrange such a corner only using ready-made corners.

    How to make a corner of a ceiling plinth without a miter box

    Few people in apartments or houses have angles of exactly 90 °. Small deviations are easily corrected after fitting. But not always. Then you have to mark everything “in place”. under the ceiling.

    You will need a finely contoured pencil (hard. it is not so visible on the ceiling, but leaves quite clear marks near), a small piece of plinth, a ruler and a good stationery knife if you work with polyurethane (polystyrene) baguettes or a metal saw to work with other materials.

    Apply the plinth to the corner, draw along the outer edge with a pencil. Apply to the other side of the corner, also mark. You have a cross on the ceiling, the center of which marks the place where the plinths of the ceiling plinth should converge (look at the photo). Having installed a piece of plinth in the corner, which will be glued there and resting it with its end on the wall, transfer the mark to it.

    properly, inner, corner, ceiling

    How to make corners on skirting boards without using special tools

    Now take a ruler and connect the edge of the skirting board with the marked mark. If you just put the plinth on the table and cut along the mowing line, the two parts in the corner will still not fold: the inner part will interfere. It can be trimmed later by trying on the ceiling. The second way is to set the piece to be cut on the table with the piece that will be on the ceiling. And cut along the mowing line, but holding the knife at an angle of about 45 °. It will still be necessary to correct, but much less (and less chance of error).

    Repeat the same operation with the second bar. Put it against the desired wall, rest the butt against the adjoining wall, mark the place where the cross is drawn, draw the line and then cut it off. Correction Carried out “dry” without applying glue.

    You repeat exactly the same steps for the outer (protruding) corner. Now you know another way to make a corner of a ceiling plinth, and without a scissor or other special devices.

    Using a miter box

    If the corners and walls in the room are even, you can use a special carpentry tool. a miter box. This is an inverted U-shaped chute in which the mowing line is marked for cutting at 90 ° and 45 °. The part in which you need to make a gash is laid inside, a saw is inserted into the guides. The part is held in place, cut at the desired angle.

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

    In the case of skirting boards, not everything is so simple: they must simultaneously adhere to two surfaces, therefore they must be pressed against one or the other wall of the miter box. When working with ceilings, they are pressed in the side closest to you.

    The sequence of actions when finishing the outer corner, you need to make a gash at an angle of 45 degrees. Place the miter box in front of you. Trying on how the plinth will be located, determining which part of it will be attached to the ceiling. In order not to get confused and cut off the ceiling plinth correctly, place the strip that will be located on the right on the right, the one on the left on the left.

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

    Press the part that is on the ceiling to the bottom of the miter box. The other side is closer to you and raised. Lean it on the wall of the device so that it does not stagger when cutting. That is, the front part of the skirting board turns out to be turned away from you. Do the cutting direction as shown in the photo below. By folding the two cut pieces together, you get a protruding outer or outer corner.

    First put the sawn-off parts in place “dry”, without applying glue. If the geometry of the corner is not so perfect, you can tweak it a little with a knife. It is easier to cover small errors with a special putty.

    The situation is very similar with the inner corner of the skirting board. First you try on which side will be on the ceiling, press this part to the bottom of the miter box, lean the second part on the wall closest to you and make cuts as shown in the photo below.

    How to make an inner corner of a ceiling plinth using a miter box

    And again, first try on without applying glue, if necessary, slightly adjust. Then apply a thin bead of glue to both surfaces that will adhere to the wall or ceiling.

    How to get the correct angle

    Most of the problems when working with skirting boards arise in the design of corners. Since the surface of the products is complex, it will not be possible to simply cut off at the desired angle: it is also necessary to cut so that they dock and, preferably, without large gaps. In reality, there are several ways to make the corner of a ceiling plinth perfect (or almost).

    With decorative corners

    There is one more, the easiest way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory decorative corners. They are installed in a corner, strips are glued to them closely. It is very easy to cut them if necessary: ​​by a few millimeters with an ordinary clerical knife.

    How and how to cut

    Working with skirting boards made from different materials means using different cutting tools. When working with a wooden skirting board, it is more convenient to work with a saw on wood. All others, including plastic ones, made of foam and other polymers, are better cut with a blade for metal. The result is a smoother cut, less burr. Saws are usually used when working with a miter box.

    Corner design looks attractive

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

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

    How to cut ceiling plinth in corners

    The quality of the ceiling finish greatly affects the appearance of the room. Therefore, they try to do everything perfectly, or very close to it. The finishing touch to the design is the ceiling plinth. They give the finish a complete and holistic look. The strips themselves are mounted on flat surfaces simply: on a special white glue, but problems arise with the design of the corners. Without knowing how to make the corner of the skirting board correctly, a lot of material deteriorates. How and what to cut it in the corners and tell you.

    Inner corner

    • Making the right measurements.
    • 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 free hand.
    • We put a hacksaw at an angle of 45 ° 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, expanded polystyrene), use a metal hacksaw or an ordinary construction knife. Then the work will be neat and with smooth edges.

    Method two. no additional tools

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

    • Apply a fillet to the ceiling, firmly pressing its even edge into a corner.
    • Draw a line along the long side of the plinth on the ceiling.
    • The same action is done with the adjacent part on the other side.
    • Mark the point of intersection of lines.

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

    The first way is with a miter box

    Professional miter box with rotary hacksaw

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

    How to cut a ceiling plinth correctly

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

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

    How to cut the corner of a skirting board evenly

    A beautiful and neat edging of the ceiling hides the joints between the coverings and is an additional element of the room’s decor. But in order for the ceiling plinth to look really beautiful, you need to be able to qualitatively join its corner joints. How to cut the corners of the ceiling plinth evenly can be found in our article. Related article: how to properly glue the ceiling plinth with glue and putty.

    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 even. If the result is not achieved and there are irregularities at the joints, you can trim the edges with an ordinary knife to a perfect fit.

    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.
