How To Cut The Outer Corner Of A Ceiling Plinth

Applying a miter box template

To cut the baseboard in the corner to the ceiling as evenly as possible, you can use a paper, cardboard or wood template instead of a regular miter box. Two parallel mowing lines are applied to it, then a central point is found and any necessary angle is laid from it using a protractor. Before you cut the corner of the ceiling plinth without a miter box, you should double-check the size of the inner or outer corners between the walls of the room, using the same protractor.

How To Cut The Outer Corner Of A Ceiling Plinth

The principle of cutting corners using a template is similar to using a standard miter box. In this case, the workpiece must be pressed against the parallel mowing line and, setting the hacksaw at the desired angle, saw off the workpiece.

Marking on the ceiling to make a corner on the skirting board

There are different ways of how to correctly make a corner on a skirting board. Some are easier to do, others are more difficult. One of these methods is to mark the plinth on the ceiling. True, cutting the plinth by weight is not very convenient, but this method is not inferior to all others in accuracy. Before cutting the plinth to the ceiling, it is applied to the surface, while all the imperfections and irregularities of the walls, as well as the size of the corners, are immediately taken into account.

Let’s consider in detail how to correctly make the corners on the ceiling plinths using this technique:

  • First, two mating plinths must be cut off at an angle of 90º;
  • One of the blanks is pressed against the wall, and its end is abutted against the opposite wall. Then the outline of the workpiece is drawn on the ceiling.
  • At the next stage, they take the second plank and in the same way press it with its butt to the wall. Outline the line.
  • At the intersection of the resulting lines, a point is set, along which further trimming of the baseboards will be carried out.
  • Then each of the strips is alternately applied to the ceiling and the cutting point is transferred to the blanks.
  • From this point to the corner of the plinth, a diagonal cutting line is drawn.

On the obtained fishing lines, unnecessary sections of the baseboards are cut off, then the mating segments are joined, checking the correctness and completeness of the fit. Read also: “How to cut a corner of a ceiling plinth. simple and correct ways”.

Using a miter box to cut skirting boards

In carpentry, a special device made of wood, metal or plastic is often used. a miter box. Special cuts are made in it, which allow you to make an even cut at 90º, 45º, and in more complex devices. even at 60º. There are also professional miter boxes equipped with a rotating mechanism. In them, the cutting tool can be installed and fixed at any angle to the workpiece. Before making a ceiling plinth in the corners, you need to understand the details.

To cut the inner corner of a ceiling plinth using a miter box, you must:

  • First, the skirting board must be attached to the ceiling surface and mark the length.
  • Now a piece of plinth is placed in the miter box in the same position as it should be placed on the ceiling.
  • The plinth is tightly pressed against the back wall of the miter box.
  • Hold the work piece with one hand to prevent it from shifting during cutting.
  • The hacksaw is set at an angle of 45º to the workpiece.
  • Cut the plinth, controlling the degree of pressure of the hacksaw, so as not to damage the product.
  • Then they move on to cutting the counter piece of the plinth. It is also applied to the far wall of the miter box.
  • The workpiece is pressed and held by hand so that it does not move.
  • The hacksaw is installed at an angle of 45º to the workpiece so that the direction of the cut is opposite to the first element of the plinth.
  • Cut off the corner of the plinth.

After trimming the ceiling plinths in the corners, they proceed to joining the resulting elements. If the cutting was done accurately, they will fit snugly together.

Let’s look at how to cut the outer corner of a ceiling plinth using a miter box:

  • It is best to start marking and measuring the ceiling plinth from the inner corner, and only after completing it, start cutting the outer corner. Otherwise, the plank may be short, it will not be enough to fill the entire length of the ceiling.
  • The plinth is applied to the ceiling and its length is marked.
  • Then the workpiece is placed in a miter box and pressed against the front wall.
  • Place the hacksaw at an angle of 45º and, holding the workpiece with your hand, saw off the corner.
  • Similarly, you must cut off the opposite part of the outer corner.
  • The workpiece is pressed against the front of the miter box.
  • The hacksaw is placed at an angle of 45º to the plinth and the workpiece is sawn off.

At the end of the work, the pieces of the plinth are joined together, checking if everything is done correctly and smoothly.

How to cut a corner of a ceiling plinth. proven methods and techniques

Ceiling skirting boards are very often used for decorating rooms. They give the ceiling a complete look, allow you to convey this or that style in the interior. In addition, they serve to mask the joints between walls and ceiling, where two different materials are mated. Although these elements are not always present in the premises, they make the interior more complete. In the material below, we will tell you in detail how to cut the corner of the ceiling plinth, since in such places the joining of individual elements is often a problem for inexperienced builders.

If the room has a simple shape, then only the inner corners will need to be cut. But in rooms of a more complex configuration, with columns, partitions and niches, there will also be external corners. To make decorative elements look beautiful, trimming must be done correctly and accurately, otherwise the appearance of the ceiling will be spoiled.

To trim the ceiling plinth in the corners as best as possible, you can use quality and sharp tools or other means. The type of tool that will be used to cut skirting boards depends on the type of material used to make them. So, ceiling plinths are made of PVC, foam, polyurethane and wood.

The cheapest option is PVC skirting boards. They are soft, so it is easy to leave dents and creases on them, which cannot be fixed in any way. In addition, this material has the ability to attract dust. For cutting such skirting boards, a hacksaw or a sharp knife is suitable.

Another fairly cheap type of material is expanded polystyrene baseboards. They crumble easily, so you should only use a sharp knife or a metal hacksaw to trim the corners of the ceiling plinth. Movements should be soft, without pressure.

Cutting skirting boards for ceiling decoration

Another type of ceiling plinth is made of extruded polystyrene foam. They are much denser than ordinary foam products (therefore they do not crumble), they are slightly more expensive, but they are also somewhat more difficult to cut. For work, you can use the same knife or hacksaw for metal.

The most expensive skirting boards are made of polyurethane. These are elastic, strong and moisture resistant products that are very easy to cut with a construction knife. True, they cannot be used in all rooms, since polyurethane is sensitive to high temperatures. it deforms, begins to crack or cracks.

For working with wooden skirting boards, only a hacksaw with fine teeth is suitable, you can use a metal tool.

How to make a miter box yourself

Often the only way to cut the corner of the ceiling plinth evenly is to use special tools so that the tool does not move to the side during the cutting process. In this case, you can make a miter box yourself.

Option 1. A box in the shape of the letter P is made of three boards. The required corners are marked on the walls of the box and the slots are cut out in the appropriate places. The result is a complete adaptation.

Option 2. Sometimes it is quite difficult to make the corners of the skirting boards on the ceiling as even as possible, especially if you have to keep the workpiece suspended. In this case, you can use a homemade device. Take two boards and knock them down in the shape of a corner. Then, on a sheet of paper or cardboard, they draw a mowing line with the desired angles, apply a template to the corner. Then the plinth is pressed, a template is placed under the cutting site and the corner is sawn off along the lines.

Option 3. If you are still in doubt about how to properly cut the corner of the skirting board, almost any household item whose shape allows you to form an angle can help. It can be a chair or a table just against the wall.

To understand how to properly cut the ceiling plinth, you should also familiarize yourself with the rule for measuring blanks. So, to complete the inner corner, the length begins to measure right from the beginning of the corner. But to determine the outer corner, it should be borne in mind that it will be issued into the space of the room by the amount of the width of the product.

If cutting off the skirting boards in the corners did not work out perfectly, small gaps can be simply putty. In general, the process of trimming baseboards in the corners is not at all difficult. However, for practice, you can take a few small pieces of the baseboard and practice on them.

How to glue a ceiling plinth, cut fillet corners correctly

Do you want to cut and glue the skirting board correctly, but don’t know how to do it? At first glance, this does not seem difficult, but if you look at it in more detail, then everything is not so simple. The photo below shows how to properly cut and glue the inner and outer corner of the ceiling plinths (fillets) made of foam or polyurethane. All instructions are written in stages in an understandable form with examples.

Masking joints and painting

If, after gluing the ceiling plinth, there are small gaps between the planks, this is absolutely not a problem, because they can be easily eliminated by rubbing in a white sealant. If you have not yet whitewashed and painted the ceiling, then the following would be the best option.

With a light putty, you need to go over all the glued strips, smearing them like a dye composition, and after drying, you should remove the excess with a fine sandpaper or a special grinding sponge for plastering. After such a final finish, the ceiling and moldings will become a single whole, and you, in turn, will not find a single gap.

After you have glued the ceiling plinth and removed all the flaws, you can start painting the plinth. The process of painting the plinth is considered optional, but if you want to give your ceiling a finished and more attractive look, then the plinth must still be painted.

How to make installation

You need to cut with the help of such tools: a miter box, a hacksaw, a sharp knife. Insert a piece of material into the miter box at a 45 degree angle and press down firmly. Now it remains at the right angle and cut the ceiling plinth from the right side.

Take your time to glue the cornices along the straight sections. Take care of the corners first. in this case, you can trim them if necessary, or sand them to get a good joint.

Now let’s figure out in more detail how the installation of the ceiling plinth is done with photo examples.

How to cut the inner and outer corner of the ceiling fillet with a photo

Thus, we cut the plinth, if you need to get an outer corner.

As a result, these are the edges of the fillet.

Then the inner corner. Pay your attention, but at what angle and on which side of the miter box you need to cut the ceiling plinth.

Here’s what happened in the end, after cutting and gluing on the wall.

Do-it-yourself apartment renovation website advises to start practicing on pieces, if everything works out, then go ahead, cut out the inner and outer corners.

If everything was done correctly, then it turned out to cut the first corner. You can glue two corner skirting boards to the wall. If you have chosen the method of gluing on the wallpaper, then coat the fillets with glue and attach them more tightly to the wall. Remaining glue can be removed with a soft cloth. Also cover the cracks between the wall with glue.

If you have chosen a way to fix the ceiling skirting boards before gluing the wallpaper, then you need to fix them with a putty. Apply the putty to the fillet with a spatula. And attach it more tightly to the wall. Remove residues with a spatula or a damp cloth. The cracks can also be covered with putty.

Tips to ease the installation of ceiling dumbbells:

  • To correctly measure, the bar is measured between two corners. In this case, for internal corners, the length is measured from the internal elements, and the distance from the external corners is measured from a point that is spaced from the internal by a distance equal to the width of the plinth deep into the room.
  • When installing foam plinths at the junction between the wall and the stretch ceiling, glue is applied to the part of the plinth in contact with the wall, not with the canvas.
  • The final fixation of the plinth is carried out after adjusting the angle of the adjacent plank to it.
  • If there is a right angle near the wall, ceiling and floor, it is easier to fit the planks at the bottom, spreading the parts on the floor or on a prepared table.
  • Small gaps remaining in the corners are putty.
  • Particular attention should be paid to the installation of rare wood skirting boards. In this case, the putty of the gaps will most likely not give the expected result. A bright spot appears on the texture background.

Well, are the inner and outer corners ready? So you are doing the fillet installation correctly. Now take the next plank and in the same way attach it to the wall to the glued plinth and do not forget to grease the corner joint. When you proceed to the next corner, then carefully measure the distance that remains, and cut off the missing part, everything should be very accurate. The side that goes joint to joint with the skirting board will remain unchanged. So cut out every corner. When everything is glued, then they can be painted to match the color of the ceiling. Good luck gentlemen and remember that you need to cut after determining the exact size.

How to properly glue the ceiling plinth

So let’s get started. First, measure the footage of the perimeter of the room and determine how many fillets you need. The length usually goes according to the standard 2 meters. But it is best to purchase with a margin, just in case. Also decide on the width that suits you. They can be glued to the wall in different ways.

The first way: on a special putty or acrylic (before gluing the wallpaper). And the second: immediately on the wallpaper and on the sealant.

Most people prefer to attach directly to the wallpaper. As an option, we advise you to glue on a silicone sealant, it is perfect for this job. The manufacturer does not play a special role here. Everything will hold up perfectly. But this method is even suitable for those who have curved walls, since gaps can form between the wall and fillets, they will need to be covered with the same sealant. It is white, so it will turn out more or less normal.

It is advisable to align the walls. The master advises to glue the ceiling plinths on the putty, that is, before pasting the wallpaper. In this way, the gaps are filled with a putty. And accordingly, adjust the wallpaper to the fillets themselves. This option will suit the more experienced.

Basically, craftsmen prefer to glue the foam plinth on an acrylic white sealant; it can be easily applied, it holds well and dries quickly. Its main property is that it can fill up cracks, corners and it can be painted well. The cost of acrylic sealant is within 100 rubles. And it doesn’t make much sense to buy dear.

In general, everyone decides for himself which way to use.

Way, guess

A simple “collective farm” option is to cut “by eye” at 45 °. For this, the abutting part is taken, which is adjusted to the previous angle in fact.

You can try on the structure by weight, it is quite a long and painstaking business. Need maximum precision!

Continuously try the mate in place as you fit. Only after several fittings can you achieve a good result, and then glue the baseboard to the base. In short, you can’t do without experience 🙂

A way to fit a skirting board without using a miter box

If the angle is not right

Unfortunately, in some cases, the angle between the walls in the room is not straight, but sharp, or, conversely, obtuse. This is due to structural defects that have arisen through the fault of non-professional builders, the architect’s idea or the result of soil subsidence some time after the construction of the building. This is especially common in village houses and summer cottages.

No miter box or a drawing replacing it will help in this case, and you will have to do the markup in place.

  • Attach the workpiece to one of the walls so that it rests against the other wall with its end.
  • Run the line on the ceiling along the workpiece.
  • Perform the same operation against another wall.
  • At the intersection of two lines, put a mark on the workpiece itself.
  • Draw the line from the mark to the corner of the workpiece and cut along it.
  • Do the same with the workpiece, which you will attach to another wall.
  • Glue both blanks; they will come together tightly.

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 cut a ceiling plinth with a miter box template

Something resembling a miter box can be made by applying the required cut angles to paper, cardboard or wood. Draw two parallel mowing lines, locate the center, and then set the required angles with a protractor. The advantage of this method is that you can postpone any angle, including more than 90 degrees. Of course, before cutting the corners of the ceiling plinth, you must first check the angle between the walls using a corner and measure with a protractor.

The technique for cutting a ceiling plinth using a painted miter box is exactly the same as using the miter box itself. We press the plinth strip to one of the parallel lines, then set the hacksaw at the desired angle, which has already been outlined, and cut.

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 extend slightly outward.
  • The plinth is moved to the miter box and cut off.
  • The adjacent bar also needs to be measured with a margin and cut off in a mirror image to the first part.

Trying on the ceiling plinth: the joining of the parts should be perfectly flat. If the result is not achieved and there are irregularities at the joints, you can trim the edges with an ordinary knife to a perfect fit.

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 it so that they dock and, preferably, without large gaps. In reality, there are several ways to make the corner of your skirting board perfect (or almost).

How to make a miter box yourself?

If desired, the miter box can be made at home. It can be crafted from wood or iron. The dimensions of the workpiece do not play a special role, but the wider it is, the more accurate your cuts will be. However, if the width is greater than the length of the hacksaw, with which you will cut the baseboards or boards, then it will be extremely inconvenient to saw, so you do not need to take a workpiece that is too wide.

First, a transverse line is marked in the center of the workpiece. Then, marks are made at a distance of 1/2 the width of the workpiece from the intersection of the straight line with the edges of the workpiece. Then these marks are connected crosswise, as shown in the figure.

Then the process of marking the side walls of the miter box begins. Attach them to the already marked base and make marks based on the base markings. Then draw straight lines from these marks across the entire wall.

After that, the process of mounting the miter box begins. The walls must be attached to the base with self-tapping screws, if the fixture is made of wood or chipboard or corners with bolts, if it is made of steel. Only after installation in the miter box are the saw slots cut.

Inner corner

  • We make 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 hacksaw for metal or an ordinary construction knife. Then the work will be neat and with smooth edges.

    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 °. 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.

    All the nuances are well described:

    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 at perfectly flat corners.

    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 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 superimposed on the drawing and combined with the hacksaw layout.
