How to cut an external ceiling plinth

Cut off outer corners with a miter box

Place the skirting board against the corner and mark with a pencil where the outer corner begins on the skirting board.
Then the plinth is placed in the miter box. The side that will be attached to the ceiling is laid on the bottom of the miter box, and press the other side against the wall.
The mark on the skirting board should be near the slot on the left. Cut off one edge.
Then, in the same way, we cut off the other half of the corner. Only the mark on the skirting board should be located near the right slot.

We attach both halves to the corner and check if there is a gap. If everything is in order, then you can glue the skirting board in place.

Cutting method with miter box

The most popular mounting option is using household tools. The miter box is a renowned carpenter’s assistant to help you cut at the right angle. Usually it is a tray, wood or plastic, with vertical slots for the blade at angles of 45 and 90 degrees. How to cut the corners of a ceiling plinth with a miter box?

First, you should attach the material to the ceiling, install its bar in the miter box.

In this case, the tool must coincide with the position of the product. Holding the plinth with your left hand, choose a position for the cutting tool (hacksaw) at an angle of 45 degrees. Cut the material without undue pressure. After that, the striker is cut, set to the far wall of the wort.

Holding the working material with your right hand, select the position of the hacksaw at 45 degrees and cut.

Varieties of finishing products

This material is intended for decorative finishing of the ceiling area, visually separating it from the walls and covering the joints of various finishing elements. Almost any option for decoration, interior design involves the use of such details. Otherwise, the room will look unfinished.

Fillets are used to secure this part, which are attached to the ceiling with glue. But a problem arises. how to properly cut the ends of the fillets so that they successfully converge with each other. There are rooms of non-standard configuration, where ingenuity is required for normal material joining. How to cut ceiling skirting boards in the corners? There are different options for trimming and docking. with or without tools.

The choice of mounting option depends on the type of product:

PVC. the cheapest, but also the most brittle, prone to defects, but easy to use, it can be cut with a knife.
Expanded polystyrene is also inexpensive, brittle, requiring a hacksaw for metal, although it is easily cut. Another option is slightly more expensive. from extruded polystyrene foam, it is more difficult to cut it, but it crumbles less.
Polyurethane is the most expensive and moisture resistant, durable and elastic. It is more difficult to work with it, it deforms at high temperatures.
Wooden. dense and heavy material, cut only with a hacksaw.

Useful Tips

The presented tips will help you cut the corners of the baseboards as correctly as possible.

It is recommended to try on small residues before cutting large parts. Having mastered the cutting technique, you can start cutting the real parts of the skirting board.
As an impromptu version of the miter box, you can use a table pushed against the wall.
To mark the inner corner, measure the length of the plinth straight from the corner.
To mark the outer corner, the skirting board must extend beyond the corner by the width of its end.
When cutting the skirting board along the marked line, lay it on a hard surface not marked side down.
It is recommended to fix the skirting boards to the ceiling only after both parts have been cut out and their joints have been checked. It can be fixed to the ceiling if, during the check, the corners docked without gaps.
Minor inaccuracies in joining wooden or polyurethane ceiling skirting boards can be corrected with a file. For foam skirting boards. using a sharpened knife.
The gap formed as a result of fuzzy trimming can be hidden with a putty.

Cut the skirting board for the outer corner

Without a miter box, you can easily cut the fillet for the outer corner:

To do this, apply the ceiling fillet as it should stand to the right of the corner. Draw a line with a pencil on the ceiling beyond the corner.
Then we apply a fillet to the left of the corner and draw a line along the ceiling until it intersects with the first line.
On the fillet we make marks at the intersection of the lines and at the place where the corner of the room is.
We connect the marks with a line on the fillet and cut it off with a sharp knife. The cut should go inside the fillet.
We check the joint along the corner, cut it if necessary and glue the fillet in place.

it should be noted that for 1 running meter. Count the number of meters in your apartment, multiply by 100. This will be the amount that you will save if you do this work yourself.

Installation of finishes: features

Many owners of houses and apartments, in the midst of renovation work, are often puzzled by the question of how to properly cut the ceiling plinth in the corners. The problem is that it is not technically possible to make an incision at a 45 degree angle. To perform such manipulations, it is important to correctly dock at the boundaries of the outer and inner corners of the web, which is quite problematic.

The specificity of the ceiling version is not only in the vertical position of the canvas. The mount is placed at the base at an angle of 38 to 45 degrees. The difficulty lies in making a 45-degree incision. It is difficult to connect cut edges from the inside, gaps appear between them, aesthetics are disturbed.

For the most accurate cutting, a special corner element is used, which is inserted into the edge of the skirting board. it will help to hide cutting errors. This element will emphasize the corners in the room; the choice of such a detail must be approached responsibly.

Fillet cutting for inner corner

Internal corners are always present in rooms. so you will definitely have to deal with them when installing skirting boards on the ceiling. In this case, when cutting a baguette, we follow the algorithm:

we measure the required length of the workpiece by attaching it to the ceiling at the place of future installation;
we place the bar in the miter box along the near wall so that its location coincides with how it will be mounted on the ceiling;
holding the plinth, we put the cutting tool in the groove with an inclination of 45 ° and cut the workpiece without unnecessary pressure;
we do the same actions in a mirror image for the second, adjacent bar. For the convenience of cutting, you can turn the miter box with the bar installed in it to the desired hand.

Knowing how to properly cut out the inner corner on the ceiling plinth with a miter box, you can easily arrange more complex ones. outer corners.

Materials for ceiling plinths

Ceiling moldings can be of various widths, have a convex pattern on the front side and special recesses for engineering systems on the back side. Fillets are made in specialized production from polystyrene, its varieties. expanded polystyrene, polyurethane and wood.

Polyfoam is the most affordable finishing material. Its positive qualities: light weight, ease of cutting and processing, the possibility of finishing by painting in any color. Negative point. granularity and low strength. even a slight mechanical damage can disrupt the integrity of the foam surface.

Varieties of foam plinth Foam plinth on the ceiling

Expanded polystyrene is a more durable type of foam. It is also light in weight and in processing, but it has a higher density and a smooth surface, is more resistant to mechanical damage, and lends itself well to staining. These two materials, due to their low weight, have little stress on the load-bearing walls.

Wood is the hardest and most impact-resistant of all fillet materials. Products made from it retain their appearance longer and are able to withstand significant mechanical stress. In the style of some interiors, it is wooden friezes that are most applicable. Wood ennobles the room and fills it with warmth. However, it has a higher price than previous materials.

Different types of baguettes made of wood Wooden fillet in the interior

Products made of polystyrene, as well as expanded polystyrene, have an advantage over wood. The softness of the material makes it possible to press the baguette as tightly as possible against the wall, ceiling and each other. so there are no gaps. It is possible to achieve excellent joining of the plinth on not perfectly flat walls if you use a not wide foam or expanded polystyrene fillet.

Skirting tools

When installing friezes, you need to prepare the necessary tools to perfectly cut the skirting board and fit the ceiling frieze to the corners of the room. To trim the baguette, a miter box and cutting tools are used: knives (carpentry and ordinary), hacksaws, saws. When handling each of them, it is necessary to take into account the features of the device and the subtleties of application.

The miter box is a device that guides the cutting tool blade with the required inclination. It is specially designed for cutting materials that are then mounted at a specific angle. Structurally, it can be conventional and tilt-rotary, or precision. They are visually different, but the principle of operation is the same.

Different types of miter boxes Plastic miter boxes with clamps

An ordinary miter box is a U-shaped tray made most often of plastic. It also comes in metal or wood. There are slots in its walls for guiding the cutting tool at a given angle to the base. This variety has a template type and cannot be adjusted: the material is cut at standard angles (normal or negative), which are structurally embedded in the grooves. When choosing a miter box, you need to look so that it should be wider than the workpiece for cutting. To fix the material in the device, a clamp or special pins can be used. if the structure has perforations for their installation. Usually, the workpieces in it are simply held by the free hand.

Plain plastic miter box Plain wooden miter box

Swivel, or precision miter box. by adjusting to any angle of inclination, it allows you to cut at an angle and get a simultaneous cut in two planes at once. It is a professional tool that is rarely used under normal conditions.

Swivel miter box with hacksaw Precision (swivel) miter box

Saw. Recommended mainly for hard wood skirting boards. Using the saw on soft materials such as styrofoam and polystyrene is not always a good idea. The cut from the saw turns out to be rough and requires additional grinding with sandpaper or a file.

A hacksaw is a widely used cutting tool for cutting a baguette. It is necessary to carefully approach its choice: the canvas must correspond to the size of the slots in the miter box. be of sufficient thickness and width. When working with a hacksaw, it is necessary to observe the inclination of the tool so as not to damage the miter box and observe the correct direction. At the same time, the cut of the part often turns out to be not very smooth and sometimes requires alignment and grinding.

Construction knife. makes it easy to cut soft foam fillet. It is not difficult for them to work, and the cut turns out to be even and smooth. Instead of a construction knife, it is permissible to use an ordinary knife. the main thing is that it is of sufficient sharpness and length.

Trim skirting in miter box

The miter box is one of the most important tools when processing a baguette, allowing you to make cuts on the skirting board with the desired slope for an even joint. Consider the features of working with fillets using this device.

To correctly and evenly cut the ceiling plinth using a miter box in the corners, you must follow certain rules.

Cutting workpieces with a miter box is only suitable for 90 ° right angles.
When cutting a baguette intended for the ceiling, it is applied and sawn on the inner side of the miter box closest to you.
The workpiece is installed in such a position as it will be mounted later on the ceiling.
Cutting is carried out on the front side of the baguette.
The side that is subsequently glued to the ceiling must press firmly against the bottom of the tray when cutting.
It is recommended to use a specific cutting tool for each type of material: a hacksaw or knives are good for cutting soft materials such as foam, a saw is preferable for wood.

Ceiling corners can be internal and external, or external, therefore there are differences in the preparation of the baguette, which consist in the methods of joining the planks and the different inclination of the cuts. To make it easier to work with the miter box, it is useful to make visual prompts on it in the form of small stickers with inscriptions, as shown below.

Miter box with tips for easier work Angle types

The main attention should be paid to the accuracy of cutting workpieces at the desired angle. It is recommended to start working from the inner corner and then work to the outer corner. Otherwise, it is possible that the length of the baguette will not be enough. Schematically, the cutting steps look like the figures below.

How to properly cut a corner on a ceiling plinth

Ceiling plinth, also known as fillet, frieze or baguette, is a finishing material that is used at the final stage of the renovation of the premises. At the same time, it not only masks possible irregularities of the upper edge of the wallpaper or peeling of plaster near the ceiling, but also acts as a decorative element, giving completeness and uniqueness to the space.

Ceiling plinth with internal and external corners

Many people install the ceiling frieze in their apartment on their own, without involving masters. This job is not that difficult if you know how to choose the tools and cut the corner correctly on the skirting board. The main thing when working with a ceiling molding:

take into account the peculiarity of the material from which the fillet is made;
have the right tools and use them correctly;
know the intricacies of step-by-step work.

Fillet cutting for outer corner

Outside corners in a room are not so common, but they require particularly careful cutting of fillets and precise joining of their sides. Unlike the internal ones, small gaps in the external ones are more noticeable and difficult to hide. You also need to take into account some peculiarities when working with external corners. It’s easy to do, following certain rules:

parts of the frieze should protrude slightly from the edge of the wall, forming a small margin;
we measure the bar by attaching it to the ceiling as it will be glued in the future;
we place the frieze in the miter box, pressing it against the wall closest to you;
insert a hacksaw or other suitable cutting tool into a groove with an angle of 45 °, and cut off the workpiece without unnecessary pressure;

The location of the outer left strap in the miter box

we put the adjacent bar to the nearest wall of the miter box and, holding it, insert a hacksaw or other tool into the groove at an angle of 45 °. For the convenience of work, we unfold the miter box with the workpiece “under the arm”;
we do the same as in the previous case. carefully and evenly cut the fillet.

It remains to join the cut baguette strips and check the cutting accuracy. Taking the cut pieces of the baguette in pairs, we join them, forming an inner or outer corner. If the cutting of the planks was carried out accurately and accurately, then the edges of the adjacent planks will ideally coincide with each other.

Cutting without tools

How to cut a corner of a skirting board without a miter box? It is possible to perform the calculation and cut manually. It is enough to make a good marking on the ceiling, then cut off the desired corner exactly. A significant disadvantage of this option is the inconvenience when you have to hold all the bars with your hands during the measurement process. In general, this method helps to make the necessary measurements just as well.

By attaching the product to the place where it will be mounted, you can immediately take into account all the errors on the walls. First, two workpieces are cut at an angle of 90 degrees. Then one of the planks is applied, resting it against the wall perpendicularly. Draw a line along the ceiling, outlining the desired contour. Then they remove the bar and apply a second one. for reciprocal markings. The intersection of the lines will be the cutoff point. Then a place for the future cut is marked on the slats.

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 a line from the intersection to the edge of the part. Note that the above marking method works only at perfectly flat corners.

Angle slicing

How to cut ceiling skirting boards in the corners? The secret of a high-quality incision is in making cuts both on the outside and on the inside. The inner cut matters if we make the outer corner.

Usually, professional equipment is used. miter saws or industrial electric rotary hammers. But supporters of home renovation can get by with conventional tools. The main requirement is that at the end of the work, the result should be a clearly visible texture for the cornice, reflected on its front or back side.

How to cut the corners of a ceiling plinth?

No matter how expensive repairs you start, you will hardly be able to avoid irregularities on the border of the wall and ceiling. In order to hide them, use a ceiling plinth.

How to cut the corners of a ceiling plinth?

Since the average person does not have many specialized construction tools in his arsenal, we suggest that you familiarize yourself with the recommendations on how to cut the corner of the ceiling plinth using simple tools. To do this, you will need:

The miter box is a tray with special slots at different angles. Such a tool is a necessary thing in the household, moreover, it is inexpensive. To trim the corners of the skirting board, you just need to take a miter box with angles of 90 and 45 degrees.

To cut the corner of the ceiling plinth, follow these steps:

we apply the plinth to the ceiling and measure;
we lay the plinth on the bottom of the miter box so that its lower part is pressed against the wall of the tool;
carefully cut the plinth with a metal saw along the slot of the tray, where the angle is 45 degrees. Do not press hard so as not to damage the skirting board;
similarly, the adjacent plinth is cut along another 45-degree slot;
attach two skirting boards to the place where they are glued and, if necessary, remove minor irregularities with a sharp knife.

As you can see, there is nothing difficult in this operation. But how do you cut off the corner of the skirting board if you don’t have a miter box? There is an exit. You need to proceed as follows:

cut the plinth at a 90 degree angle and attach it to the corner on the ceiling;
draw a line on the ceiling at the edge of the baseboard;
on the opposite wall, do the same with the adjacent skirting board;
the point of intersection of the two plinths on the ceiling is alternately transferred to the plinths, mark with a pencil;
we draw a straight line from the marked point on the plinth to its sharp opposite edge. this will be the cut line;
cut the plinth very carefully with a sharp knife.

If in this case you cannot make the cut even, draw lines with an intersection of 45 degrees on a sheet or board and attach a plinth to them so that the line drawn on it corresponds to the indicated angle. It is better if someone helps you in this case and fixes the ceiling plinth on such a homemade miter box so that you can cut the edges evenly.

It happens that the unevenness of the walls does not allow the skirting board to be glued evenly, even after it has been perfectly cut. In this case, you need to determine the trimming degree individually. This is why it is so convenient to use a homemade painted miter box.

To avoid ruining your skirting board, practice doing it in small pieces before trimming it. Thus, you can “fill your hand” and make a cut more confidently every time.

How to cut ceiling plinths in corners with and without a miter box?

November 11, 2015

The procedure for installing fillets on ceilings seems to be quite easy, but it requires specific techniques to successfully complete the repair. Often we cut the corners of the ceiling plinth completely incorrectly, which leads to a reduction in its service life and a low quality of repair work. Correct joining, evenly fixed edges is a completely achievable result, if you use the recommendations of experienced specialists.

Choosing a tool for cutting different materials

Fillets made of expanded polystyrene. despite their softness and low strength, it is difficult to work with them. They crumple, crumble, bend. To fix them, you need to make a certain effort, but dents remain on the foam, even after light pressure. You can get a straight line only with a very sharp blade. It does not pressurize the trim and easily penetrates the soft porous structure. As a rule, use a carpenter’s or kitchen knife, or a hacksaw with fine teeth.
Polyurethane and plastic products. they are much stronger and denser than foam. The surface is more difficult to crush. A special tool is used for cutting. the saw will crumble the butt, and it will take too long to work with an ordinary blade. If there is no such device, a long sharp kitchen knife or a saw with fine teeth will do.
Wooden baguette. the butt can be cut with a wood saw. Hardwoods such as oak are easier to cut with a metal hacksaw.

How to calculate the line of connection of parts on their sides

On the back upper side of the plinth, a distance equal to its width is laid. It is measured from the edge and a line is drawn parallel to the end. On the upper face, it forms a square with it, on the side, if its dimensions differ, an elongated figure.

Coving & Cornice Mouldings – Cutting an External Corner

When finishing a column or a free opening, the markings are applied as follows: from the corner of the bar facing the room, a hypotenuse is drawn from above, dividing the square in half. Its projection is transferred to the face facing the wall. For this, the space measured on the edge is also divided in half along the diagonal, drawing a line from the hypotenuse. The extra piece is cut along the two resulting diagonals.

If the joint is facing inward, the diagonals are drawn in the opposite direction.

External joint

In this case, the parts are also fixed. To cut the lath pressed against the left sidewall, insert the saw from the right.

In the case when the rail is an integral part of the external and internal joint, the internal joint is first drawn up. Then the rail is applied to the installation site to make markings for the external one. Doing it right away is very risky. You can cut off the excess, and then the length of the prefabricated element will not be enough. There will be a noticeable gap. It is easier and faster to perform the actions in the correct sequence. Step-by-step instructions on how to cut the corner of the ceiling plinth with your own hands, see the video.

Inner joint

Before gluing the ceiling plinth and cutting the corner, it is applied to the installation site. This is necessary not only in order to check how even the base is. This makes it easier to understand in what position the part will be located, and to properly lay it in the miter box. Let’s imagine that its bottom is a ceiling. Let’s place a rail in it. We turn the tool towards us with the open side, from which the main part of the baguette, intended for installation, looks out. Now press the baguette with its perpendicular back faces to the bottom and left wall. Insert the saw into the holes so that its handle is on the left and closer to us. When working, do not press on the handle, otherwise dents will remain on the edges. The blade should be moved smoothly, trying to avoid burrs and chips.

If the holes in the sidewalls are too wide, you have to pay attention to the distortion of the saw. When making a miter box, it is advisable to take into account the thickness of the blade. The product should be easy and free to cut. A gap with walls is necessary, but it is better to keep it to a minimum. this will simplify the task and help to avoid mistakes.

One of the most crucial moments is the final stage, when the cut has almost reached the end. The hanging part of the workpiece must be fixed in your hand. Plastic and Styrofoam often buckle under their own weight, creating dents. Wood can crack along the grain. As a rule, the bottom of the front part suffers. Dents cannot be fixed. The array will be easy to glue, returning the piece that has come off to its place. It will need to be cut and secured to where it came off. You can use PVA glue, “Moment”, any other composition. The chip is firmly pressed against the smeared surface. Excess glue is gently removed with a rag or napkin.

The second bar is a mirror image of the first one, so we apply it to the right side of the miter box. The rest of the technology does not differ from the manufacture of the first bar. It is cut at the same angle, but from a different sidewall.

How to cut the corners of a skirting board: tips and a detailed plan

During the renovation, everyone faced a problem. how to cut a corner on the ceiling plinth. Even with the correct marking, it is not possible to saw off the fillet strictly along the line. it bends, crumples and crumbles. It is not possible to fix it exactly in the hand at the desired degree. Vices and other attachments leave noticeable dents. Even if you cut perfectly flat workpieces by hand or on a machine, there will be a large gap between them during installation. This is despite the fact that on the floor, when fitting, the parts form a perfect connection. The conclusion suggests itself that it is impossible to carry out the fitting at home and the help of professional builders is required. Fortunately, things are not so bad. You can handle the task yourself.

Methods for joining factory products

Use of ready-made corner pieces that are glued to the inner and outer sides. They produce wide and narrow baguettes. They differ in material, shape and color, but it is not always possible to choose them for the interior.
Internal ceiling connectors. regular strips are glued to them. These connectors fill the interior space formed by the straight ends of the rails at 90 degrees to each other.
Docking couplings. the baguette is inserted inside the docking decorative boxes.

The size and shape of the parts must match the basic set of profiles.

How to trim ceiling plinths in corners using a miter box

In the middle of the workpiece, a square is drawn and grooves are made along it in the sidewalls to the very bottom. Placing the saw in the farthest furrows will give us the 45 degrees we need. The sides should not bend or wobble when cutting, otherwise the blade will get stuck in them, and the cut will turn out to be uneven. You can only work with products made of solid materials that keep their shape well. You need to make sure that the product is absolutely reliable, and its sides will not fall off at the most crucial moment. Handling a sharp object can cause injury.
