Cut the inner corner of the skirting board on the miter box

2nd December 2021

The ways

There are two most common methods for cutting flawless skirting corners correctly, easily and comfortably. The first implies the purchase of a special miter box with a large number of cuts along its perimeter, which help to cut the corner correctly and evenly. The second option is cutting corners without the help of a miter box, which we will talk about today. This process for beginners is quite complicated and painstaking, besides, the presence of a miter box does not guarantee 100% facilitation of this work, be prepared for the fact that the first time you may not succeed.

There are several ways to create corner joints without using a miter box.

One of them is the marking directly on the ceiling. To get started, we need two pieces of baguette cut at a 90 degree angle. It is not necessary to take two-meter slats at once and try to cut them, you can cut off two pieces of 15-20 cm for easier holding with one hand in the position you need. Next, we apply them in the next order to the ceiling and draw a 5-centimeter line along the ceiling to the end of the baguette, pressing the plinth tightly. After that, we apply a second molding to the opposite corner, and do a similar action, and at the intersection of the baguette and the previously held mowing line, we make a neat pencil notch on the baguette. With the second plinth, you need to repeat the same thing, making a similar notch at the intersection of the baguette and the mowing line.

Now we can cut the baguette at the angle we need, for this, use a construction knife or a hacksaw, depending on the material from which the skirting boards are made (below we will tell you what materials the baguettes are made of and what is better to cut them). To cut the corner correctly, place the baseboard on the table or chair, and cut from the point you marked on the ceiling to the opposite corner of the baseboard. After that, you can easily join the corners and glue. It must be borne in mind that this method is suitable for fitting only the inner corners, it will not work to fit the outer corners.

The second method consists in tracing a sheet of paper or plywood under the miter box, for this you need to draw two parallel mowing lines, then draw a perpendicular from one mowing line to the other, so we get a marking for a right angle. To mark at 45 degrees, you need to use a clerical triangle or a protractor, passing two mowing lines through the perpendicular at 45 degrees relative to parallel lines. Further, as when working with a miter box, we put our plinth along the mowing line and cut at the required angle.

The third method is to make a primitive miter box with your own hands, which is why it will not become less effective. To do this, take three planks or planks and knock them down in the shape of the letter “P”, make slots at right angles and two slots at 45 degrees. This way you cut corners without the “help” of the chair.

The fourth method is quite rare and inventive. it consists of tricks with thick paper or cardboard and a small bar. To do this, bend a sheet of cardboard at the angle you need, take a small block, which will serve as a template for cutting the corner. Press the prepared sheet of cardboard to it and, holding the knife or hacksaw strictly vertically, carefully cut the block at the angle you need. To trim the skirting board, simply place the piece on top of the skirting board, press firmly and cut along the mowing line of the piece.

The fifth way is the purchase of special fittings with ready-made ceiling corners: internal and external. Unfortunately, there are a lot of skirting board design variations; special inserts may not be found under your skirting board. But in general, it is very convenient for those who do not want to engage in cutting out corner joints.

But also if there are non-standard angles in your house, then ready-made blanks or a miter box will not help you. After all, there are only 45, 60 and 90 degrees you can cut the connection. In this case, cut the edge of the baguette by eye at an angle of 45 degrees, and when trying on to your corner, carefully trim it, so you will be able to achieve an almost perfect connection, with only one thing. there can be a lot of such fittings and trims.

How to make a miter box template with your own hands

If you don’t have a miter box, you don’t have to buy a one-time tool. You can make a template with similar functions yourself.

To do this, the required cut angles are applied to wood, paper or cardboard.

Then you need to draw a pair of parallel lines, find the center, and then use the protractor to measure the angles of any given value.

This method is especially convenient in that, using it, you can postpone an angle of any magnitude, even more than a straight line.

The technique of processing a skirting board using a homemade tool is practically no different from working with the original. The bar is pressed against one of the parallels, after which the hacksaw is set at the required angle and cut off.

Remember that before you cut the corners of the workpiece, be sure to check the angle between the walls! To do this, use a protractor and a corner.

How to cut a ceiling plinth correctly. Important little things

The measurements required for trimming the skirting board to the ceiling should be done in a special way. To determine and mark the inner corner, the length must be measured from the corner itself. To mark the outer corner, it must be taken into account that the plinth will protrude deeper into the room by a distance that is equal to its width.

It is not advisable to fix the plinths of the plinths until their exact location is tried on and the counter plinth is cut. Only after perfect convergence in the corner of both strikers can you begin to mount and fasten them. If work is carried out with polyurethane or wooden skirting boards, defects and flaws can be corrected with a nail file or file. To fit a foam product, you should arm yourself with a sharp knife.

If even after finishing the skirting boards there is even a small gap, do not rush to get upset. it is easy to close it up with ordinary putty. Cutting the ceiling plinth accurately and neatly is not that difficult. But in order to acquire at least a small skill, first try to practice on small blanks.

Corner trim

First you need to take a couple of blanks, then cut them at right angles. Pushing the end of the plank against the perpendicular wall, apply one plank. We outline the fishing line on the ceiling along the contour of the plinth. We remove the first bar, then, in the same way, resting the butt against the wall, we apply the counter bar. In the same way, mark the line along the contour.

The intersection of the two separate lines is the mark at which the workpiece is cut. Each bar is applied to the surface again, on both the point of the future cut is marked. From the found point to the other edge of the plinth plank, draw a line. We cut the skirting boards according to the previously made outlines, carefully join them, place them in the place of their installation.

This method allows for more accurate processing of inner corners.

Used tools

The traditional method of designing corners involves trimming them.

Therefore, we will need the appropriate tools:

wood hacksaw with fine sharp teeth. for solid wood parts, veneer wood and fiberboard;
saw for metal or plastic. for polymer fillets (foam, polyurethane, polystyrene);
painting knife with a long sharp blade. for trimming thin foam parts.

Among the additional devices that we will use in the process of work, it is worth noting the following:

Special attachment for difficult angles

a rack or trestle for mounting a skirting board under the ceiling;
miter box or a special guide frame for making cuts at fixed angles;
goniometer. allows you to fix the cutting tool blade in any position.
gun for glue or sealant;
spatulas for removing old finishes;
brushes and rollers for priming the base.

Naturally, we will need the skirting boards themselves, as well as glue for their installation. The price of a high-quality adhesive is quite high, but it is not worth saving here, especially if we install fillets made of natural wood or install massive decor made of polystyrene / polyurethane.

Docking by marking

The instructions for forming an angle without the help of a miter box will be somewhat more complicated:

First, we simply cut the panels to length, adjusting them to the size of the wall.
Then we apply one piece to the installation site and draw with a pencil on the ceiling and wall of the mowing line, marking the position of the upper and lower parts of the profile.
We do the same with the second part, getting the resettlement point at the top.
Opposite the intersection point, make a mark on the plinth, which we then connect to the bottom corner with a straight line.
We put the plinth on the workbench and trim along the mowing line. We adjust the second fillet in a similar way.

Checking for gaps when mounting the inner corner

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.

ReLend.ru »Repair technology» How to make a corner on a ceiling plinth using a miter box. step by step instructions

Ceiling plinth is a decorative element that separates the wallpaper or tile from the wallpaper on the wall. It completes the look of the room and completes the decor. However, in order to correctly join the two strips of the skirting board in the corner, it is necessary to cut it off correctly. How exactly is this done? There are several ways to achieve your goals.

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.

Approximately

With enough experience, neither a miter box nor a marking is needed. In this case, the master simply applies the skirting boards to the wall, estimates the size of the angle, and makes a cut by eye. But this method is permissible only with a very large experience, when the finisher has a correct eye and a very accurate hand. If this is not the case, this method is highly discouraged: you can spoil two parts of the plinth at once without achieving a proper fit.

This video will show you how to cut corners on skirting boards.

Hand Right IMPORTANT: Eye fit is more suitable for plastic and foam elements than wood. They are easy to cut with a knife right in place. and with a strong hand and a correct eye, everything will sit perfectly. The tree must be sawed. and the cost of a mistake is extremely high.

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.

Cutting features

Let’s take a closer look at how to properly cut a corner on the ceiling plinth using a miter box using different materials.

External

For the outer corner, the plinth is applied to the right side of the miter box (or to the one closest to you, if the template is placed across the desktop), aligned along the plane and the wall, and then cut off or sawed off using the template.

Interior

For the internal. the same, but in the opposite order: the attachment occurs on the left or far side of the miter box.

Both trimmed skirting boards are applied in place without gluing. If there are gaps, the fragments are fitted to each other with a knife. Small defects can later be covered with putty. It will also be useful to read the article on how to make do-it-yourself wall putty.

Hand Right IMPORTANT: Even when using a template, trimming corners requires some skill. Therefore, for the finisher doing this for the first time, it is recommended to first practice on the unnecessary remnants of the baseboard, cutting them off, and trying to dock without gaps.

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 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.

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 of 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 saw 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.

Materials for ceiling plinths

Ceiling moldings can be of different 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. grain size and low strength. even a slight mechanical damage can violate 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. therefore, there are no gaps. It is possible to achieve excellent joining of the plinth on not perfectly flat walls if you use not a wide foam or expanded polystyrene fillet.

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 renovating a room. 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 so 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 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.

How to Cut & Install Skirting Board, Baseboard Internal Corners

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 left outer 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.

In the presence of small irregularities and roughness, it is allowed to work on them with a sharp knife, clean them with a file or emery paper fixed on a bar.

The layout shows how a properly cut and mounted fillet will look in finished form on the inner and outer corners.

Inner skirting board on the layout Outer skirting board on the layout

Following all the rules and principles of working with special tools when preparing fillets, you can easily independently install any ceiling skirting boards.

Step-by-step instruction

When installing a ceiling plinth, first of all, you need to prepare the surface before gluing the plinth, it must be cleaned of minor irregularities, then you need to prime the gluing points to create maximum adhesion between the glue and the wall or ceiling. The primer is the same as that used for wallpapering or ceiling tiles.

Before gluing, it is recommended to take a small piece of baguette and practice cutting corner joints so as not to spoil the excess.

Now that you’ve got everything set up, it’s time to start the process of cutting out the corners. To create an inner corner, the first of the methods described above is perfect for you. If you have smooth walls, you can cut off equal pieces from the baguettes, and cut out corner joints from them, then simply gluing long strips carefully point-blank to them. These manipulations will make it easier for you to work when trimming and exclude the possibility of bending the baguette or breaking it.

If the walls have flaws, and you are worried that the gluing place will then be noticeable, you can adjust the corner on the floor, and then glue.

When cutting out the outer corner, it must be remembered that the inner corner rests against the wall, and the outer one, on the contrary, protrudes above it. Similar to the method described in the first method, you can try. The only difference will be that the skirting board should go beyond the wall to the width of your baguette plank. After trimming the planks to the desired angle and connecting them, you may need to manually correct the angle, since the angles in our homes are often not nearly 90 degrees. The rest of the methods we have described will allow you to more easily make the outer corner. Just like cutting an inner corner, it’s best to practice first. this will make your job easier and reduce skirting waste.

Before gluing the skirting boards, you need to make sure that the joints fit exactly. Modern assembly adhesives set very quickly, so you will have practically no time to correct the mistake, and tearing off the plinth is both an opportunity to break it, and the need to re-clean the surface of the plinth and wall from the glue. It is better to remove excess glue immediately with a small clean rag or sponge so that there are no traces left.

With the right patience and the right fit, you can achieve a “seamless” joint and your molding will look solid, making it easier to paint and eliminating the need for a finishing putty to smooth joint seams.

Necessary materials

The set of tools for making a corner ceiling joint without using a miter box is not so great, and, in principle, does not differ from a set with a miter box. Almost every home has these tools:

pencil;
roulette;
ruler;
construction knife with replaceable blades;
hacksaw;
ceiling plinth.

Cut 45 degree corner skirtingboard, how I cut an external mitre, outside corner on skirting boards.

You will need a tape measure and a ruler for accurate measurements and drawing straight lines, everyone has them in the house. It should be borne in mind that without a ruler, you will not be able to draw even mowing lines for cutting corners using the first method.

A construction or office knife with replaceable blades is an indispensable assistant in the house. Its cost, like a construction pencil, is low, and it is always available, it will give you the opportunity to cut off the necessary segments easily and evenly, cut out a corner or cut thin plates when adjusting the connection. Some skirting boards are made from a material that is recommended to be cut with a knife only, and not with a hacksaw due to the softness of the material.

You will only need a hacksaw if the material from which the baguettes are made is recommended to be cut only with it. A regular hacksaw with fine teeth will do.

A ceiling plinth must be chosen for both aesthetic and practical reasons. It should harmoniously fit into your design, cover the joints of the ceiling and walls, hide defects and irregularities. When choosing a baguette, it is necessary to take into account the material from which it is made. this affects the choice of cutting tools and glue for installation, as well as the type of coating on which the skirting board will be glued.

The ways

There are several ways to create corner joints without using a miter box.

One of them is the marking directly on the ceiling. To get started, we need two pieces of baguette cut at a 90 degree angle. It is not necessary to take two-meter slats at once and try to cut them, you can cut off two pieces of 15-20 cm for easier holding with one hand in the position you need. Next, we apply them in the next order to the ceiling and draw a 5-centimeter line along the ceiling to the end of the baguette, pressing the plinth tightly. After that, we apply a second molding to the opposite corner, and do a similar action, and at the intersection of the baguette and the previously held mowing line, we make a neat pencil notch on the baguette. With the second plinth, you need to repeat the same thing, making a similar notch at the intersection of the baguette and the mowing line.

Now we can cut the baguette at the angle we need, for this, use a construction knife or a hacksaw, depending on the material from which the skirting boards are made (below we will tell you what materials the baguettes are made of and what is better to cut them). To cut the corner correctly, place the baseboard on the table or chair, and cut from the point you marked on the ceiling to the opposite corner of the baseboard. After that, you can easily join the corners and glue. It must be borne in mind that this method is suitable for fitting only the inner corners, it will not work to fit the outer corners.

It should be borne in mind that this method does not guarantee you an ideal angle, and, in general, in our houses the corners are uneven. “filled up”, and therefore you will have to adjust the angle manually later.

The fourth method is quite rare and inventive. it consists of tricks with thick paper or cardboard and a small bar. To do this, bend a sheet of cardboard at the angle you need, take a small block, which will serve as a template for cutting the corner. Press the prepared sheet of cardboard to it and, holding the knife or hacksaw strictly vertically, carefully cut the block at the angle you need. To trim the skirting board, simply place the piece on top of the skirting board, press firmly and cut along the mowing line of the piece.

As you can see, in the absence of a miter box, you can still cut the correct corner joint for baguettes, you just need patience and perseverance, and unnecessary skills will not interfere with anyone in the future.

Sometimes the unevenness of the walls or ceiling prevents you from gluing the plinth along its entire length, tightly pressed against the wall or ceiling, or you made a little mistake when cutting out the inner corner, and you have a gap. To eliminate these defects, a white acrylic finishing putty is perfect. It can be painted well after drying, and with its help you can gently putty the joints. This putty is sold ready-made, you do not need to stir it with water yourself and worry about non-compliance with the proportions, depending on the manufacturer. If you want to make everything aesthetically pleasing, then spare the money and buy a small jar. According to personal observations, 0.5 kg cans of ready-made putty will be enough for you for all the flaws in the joints of the ceiling plinth, and for eliminating other minor errors during the repair.

And also for easier trimming of corners, you can use a clerical triangle, it will give you the ability to accurately cut a 45-degree angle.

One of the important factors to consider is the material from which the skirting board is made. Now they are made from PVC. polyvinyl chloride, expanded polystyrene (foam), wood and polyurethane. Depending on the material, glue and baguette trimmer should be selected.
