How to file ceiling plinth: rules for installing fillets

The main repairs in the room are completed, the wallpaper is pasted, it’s time decorative elements and ceiling baguettes. Installation of fillets does not cause any difficulties, except for the correct joining of the planks in the corners. We will tell you how to properly saw down a ceiling plinth for a neat and reliable connection of slats in problem areas.

A hacksaw with a fine tooth is what you use to cut plastic skirting board better.

Types and purpose of ceiling skirting boards

As you can see in the photo, the ceiling slats hide the top edge of the wallpaper and create a graceful transition between the walls and the ceiling.

The main function of ceiling skirting boards is to design the upper border of the wallpaper and the transition between the ceiling and the wall. A large number of straight and sharp angles, edges and regular geometric shapes, characteristic of modern cities, have a negative impact on the human psyche, since such forms are practically never found in nature.

Therefore, it is not surprising that people want to at least own home try to smooth out these corners as much as possible using various techniques and decorative elements (also find out how to cut the ceiling plinth in the corners).

Ceiling fillets are an example of such decoration, which is designed to smooth out the angle between the ceiling and the wall, creating an additional edge that comes into contact with the mutually perpendicular ceiling and wall at obtuse angles.

This makes it easier to perceive space for a person who, over millions of years of evolution, has become accustomed to natural shapes and lines, for which sharp and right angles are alien.

In addition, very often the upper border of the wallpaper is not completely flat, and also not parallel to the ceiling. And the wallpaper usually starts peeling off from the top. Baguettes not only align the line of wallpaper, but also press the top of the pasted sheets against the wall and prevent them from falling behind.

Cracks often form in the corners between the walls and the ceiling, and putty spills out of them. This place is loved by various insects, for example, spiders; it is easy for them to weave their webs at right angles.

After adding a new edge using baguettes, the attractiveness of these areas for spiders drops sharply, as does the need to constantly combat cracks, the need for permanent putty and touch-up.

The cross section of the fillet is clearly visible on the end section of the lath.

The fillet is a strip of angular section, which has three sides:

adjacent to the wall;
adjacent to the ceiling;
filling the space between them.

Perform similar planks from lungs building materials, which are easy to stick to the wall in a vertical position. The exception is gypsum, which is traditionally used in sculpting and interior decoration.

We list the main materials from which baguettes are most often made to decorate the wall-ceiling border:

Gypsum and others cement mixtures . It has been used since ancient times to create sculptures, balustrades, columns and other decorative elements of buildings and structures. It is difficult to install, heavy, and difficult to transport due to its fragility. The price is also quite high. It’s hard to say how to saw off a plaster ceiling plinth without experience working with this material;
Various types of solid wood. More often, durable and valuable varieties are used: oak, mahogany, beech, ash, Karelian birch. It has been used in construction since prehistoric times by all peoples and civilizations, due to its ease of processing and prevalence, as well as its naturalness, safety and beauty. Wooden moldings are easier to install than plaster moldings, but more complex than their plastic counterparts;
Products made of plywood, chipboard, MDF, veneered pine. The body of the plank is made from compressed sawdust and shavings, as well as from pine or spruce, pressed in a special press. In addition, the slats are often made from cheap pine, which is then covered with valuable wood veneer. Installation and performance resemble solid wood.
Hard plastics. These include: polyvinyl chloride (PVC), polyethylene, polyurethane and other polymers. They are characterized by lower cost and increased performance characteristics compared to wood and plywood.

When properly processed, some types of plastics can imitate a plaster surface and be used in conjunction with or instead of molding. Are different simple installation on glue, light weight, lightness and ease of processing.

Not afraid of moisture and detergents, like other aggressive chemicals, except organic solvents. Even an untrained installer can work with plastic slats with his own hands;

Foamed plastics. These are polystyrene foam, polystyrene foam, polyethylene foam, foamed PVC and other similar materials.

The most common ceiling plinths are made of polystyrene foam. since it is quite dense and at the same time very light and durable. Due to the foamed structure, the surface most often turns out to be porous, and it is not possible to imitate gypsum like solid polymers.

It is the cheapest material for making baguettes, while cutting polystyrene foam is also very simple. To the question “How to file a ceiling plinth?” The answer is simple: with an ordinary construction knife. Like hard types of plastics, it is not afraid of moisture and detergents.

Advice! It is important to choose the right material for a specific interior style. You should not combine high-tech with wood, classic with plywood or polystyrene foam, country and folk with plastic.

Baguettes made of hard plastics can imitate plaster well.

Installation of ceiling plinth

Preparation

The area where the parts come into contact with the walls and ceiling should be carefully treated.

Before you begin installing fillets, you must complete all the basic renovation work in the room: leveling floors, plastering, painting or wallpapering, installation, puttying and finishing of ceilings.

Sometimes baguettes are mounted before gluing the wallpaper, but this requires considerable skill during subsequent gluing, because it is not so easy to adjust the top edge of the wallpaper perfectly evenly.

If on building structures, which make up the ceiling and walls, there are any defects in this strip, they should be eliminated.

Installation of the ceiling plinth should begin only after thorough preparation of the surface.

It is also necessary to level the installation area of baguettes as much as possible, this is especially true for wooden and plaster products. Here you can use putty, putty, plaster, etc.

Advice! Protrusions on concrete and brick walls You can knock them down with a hammer drill, having previously sawed them with a grinder in the form of a grid of vertical and horizontal cuts to the depth of the protrusion. The distance between the cuts is about 10 - 20 millimeters.

After the strip has been leveled and puttied, it is necessary to wait for complete hardening building mixtures and treat the entire surface of this area with a deep penetration primer.

It can be bought at any hardware store, then diluted according to the instructions to the desired consistency and applied with a brush or paint brush to the wall in the installation area.

Preparing baguettes

When choosing wooden slats pay attention to the condition and quality of the wood.

A few words about the preparation of material. The room or other premises is preliminarily measured along the perimeter, and the value is subtracted from this value doorways, 10% is added to the result in reserve.

The standard length of one plank is two and a half meters, so we divide the resulting number by 2.5, round the result towards the next (larger) integer and obtain the number of fillets required for the given room.

Attention! If you buy moldings made from solid solid wood, then the parts should be delivered to the site no earlier than a week in advance, so that the material has time to acclimatize and change dimensions, equalize humidity in accordance with the local atmosphere and heat up. Otherwise, the slats may move into the mounting position after installation.

Also, when choosing a set for decorating a ceiling, you should ask what shaped parts and accessories are suitable for this set. It may happen that the presence of couplings and corners will save you from the painstaking process of cutting and joining the planks.

Docking and fixation

The greatest difficulty for untrained installers is joining parts in the corners of the room.

When all measurements have been completed, they begin to fix the parts in the installation position according to their purpose. You should start from the corner, where the most painstaking joining takes place.

The planks meet at right angles (or close to them), therefore, their ends must be cut at an angle of 45 degrees. How to cut a baseboard at 45 degrees?

It’s very simple: take a miter box, insert a part into it, cut it with a fine-tooth hacksaw or a construction knife, depending on the material of the fillet.

The miter box is designed for trimming parts at the desired angles.

For internal corner The cutting line should start from the bottom corner of the plank, which touches the plane adjacent to the wall. The counter strip is cut as a mirror.

Scheme for cutting adjacent planks for corner joining.

Accordingly, the planks found at the outer corners are cut in the opposite way: the cut begins in the upper corner touching the plane adjacent to the ceiling.

Next, the trimmed parts are tried on in the corner, adjusted using a file or a construction knife so that there is no gap at the joint, and glued along the upper border of the wallpaper, slightly letting the strips overlap the wallpaper. As you can see, the instructions for installing fillets are quite simple.

Conclusion

Installation of ceiling plinths does not cause serious difficulties even for amateurs. The joining of the planks in the corners is done by simply cutting the baguettes at 45 degrees at the ends according to a simple scheme (find out here how and what to glue the ceiling plinth to).

You can see all of the above more clearly by looking at this article.

High-quality repairs require careful and careful attention to detail. When finishing work with the ceiling, you need to decorate it well - ceiling skirting boards are used for this. As a rule, installing the planks does not cause any particular difficulties; you will have to tinker with the corners. Let's take a closer look at how to cut ceiling plinths in the corners, let's talk about in different ways, let's give useful recommendations on the topic.

Ceiling plinths from any material can be cut using one of the methods described below. They are suitable for all except for plastic ones: these are designed using ready-made corners.

What tools will you need?

For ceiling plinths, the following tools may be useful, depending on the chosen method of work:

Saw on wood. Useful for working with wood.
Metal cloth. Suitable for other types of skirting boards (foam, plastic, etc.).
Miter box. The tool is a groove that has the shape of an inverted U, where lines for cutting are drawn at angles of 45° and 90°.
Electric miter saw. Can be used instead of a miter box, helps achieve high precision slices.
Jigsaw. Easy to operate, it can be used to cut corners efficiently and correctly without burrs.
Stationery or construction knife. Suitable for foam baseboards, it is important that it has an excellent cutting blade, and therefore must be well sharpened.

How to make an even angle: methods

The most difficult thing is to cut a corner so as to get a perfectly flat one: the surface of the materials used is not easy to cut, in addition, you need to maintain a good fit, preferably without huge gaps. How to make a corner on a ceiling plinth? You can use several methods: with a miter box, without a miter box, using decorative corners, as well as in an alternative way.

With their help you can easily and quickly obtain the desired angles in skirting boards made of polystyrene or polyurethane. Install them on the ceiling, and then glue the strips tightly to them. It's easy to trim them using a utility knife.

How to make corners of a ceiling plinth without tools

Make the necessary marks on the baseboards.
Using a ruler, align the edge of the baseboard with the mark. If you just cut along the line, the parts in the corner will still not fit, since the inside will get in the way. You can trim it later by taking measurements on the ceiling.
You can place the piece that needs to be cut on the table, with the part that will be located on the ceiling, and cut at an angle of 45 degrees. It will require some adjustment, but not much.
Repeat points 2 and 3 for the second plank, doing outside corner OK.

In this way you can make a ceiling plinth without special tools using available means.

You don’t have to make the fillets yourself, but immediately purchase those that are initially prepared for joining. This is how polystyrene foam fillets are produced, which do not need to be adjusted to each other.

The baguette that will be fixed on the left must have a right cut, and the right baguette must have a left cut. When creating an inner corner, make sure that the lower section rises above the upper; for the outer corner, everything should be the other way around.

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

When a certain part of the plinth is glued and there is a small distance left to the corner, in order not to make a mistake with the length, you need to leave a margin. To begin with, you can cut a piece that will be 10-15 cm longer. Then cut the corner in a convenient way, try it on a dry surface, place the bar on the ceiling and select the place to which it needs to be shortened. Trimming is performed at an angle of 90°.

Next, you need to properly join the corners. Done ceiling moldings They are attached at an angle of 38-45°, so the classic 45° angle is not always suitable at the joints. IN different cases the cut edges do not meet and leave gaps. For this reason, after the initial trimming of the corners, it is necessary to carry out a “dry” and most accurate joining of the baguettes directly to the ceiling. You will especially have to tinker with wooden and plastic materials.

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

Important points

Let's look at how to correctly cut the corners of ceiling plinths and get an excellent result the first time. Follow some useful tips:

Before fastening, both parts must be adjusted to each other. Attach both halves to each other. The wall surface must be dry. If you find any defects, you can easily smooth them out with a knife.
Several trims may be required. Don't be discouraged if it takes a long time and you have to make several trims, especially if this is your first time doing the job.
Correctly determine the length of the planks in the corners. For an internal corner, the length of the strip should be adjusted exactly from corner to corner; for an external corner, the measurement is taken from the internal point in the direction of the room.
If the corners generally match perfectly, but there are small gaps in the middle, they can be sealed with putty.

How to glue ceiling plinth

Start working from the corners of the room, as they are easier to work with, then move on to other parts of the room. Seal the corners in such a way that, if possible, no gaps are formed or, if unavoidable, defects are minor. For plastic skirting boards, finishing putty is used.

Water or soil is applied to the fastening areas. After the putty mixture has dried, all cracks must be sealed - various sealants are used for sealing ( professional builders It is recommended to choose acrylic-based products). In general, one package is required per room. Installation using sealant is carried out in the same way as when using putty.

Installing a ceiling fillet allows you to hide all the flaws in the junction of the walls and ceiling, as well as give the interior some completeness and expressiveness. The process itself is quite simple, but still requires the implementation of certain rules. We will consider them further.

Description of work

The general instructions look like this:

Step #1: dismantling

Installation is not always carried out on an empty space, so you should know how to remove the baseboard from the ceiling. For this you will need:

Having prepared everything you need, do this:

Using a knife, carefully remove the paint from the gap between the fillet and the wall;
Then we drive a spatula in there, widening the gap;
We tear off the bar with a pry bar.

Tip: before performing the last step, slide it under the baseboard so that the mount rests against it.
This will keep the wall without deformation.

Step #2: selection

Here you should decide on the material, size and color. Here is some information to help you with this:

With dimensions everything is simpler:

Narrow for small spaces;
Wide - for big people.

Fastening the profile is one of the most important and responsible processes in installing a stretch ceiling. With high-quality and durable installation, the structure will last for many years and will not be deformed: the canvas will not sag, the profile itself will not break. But it also depends on how the baguette is fastened appearance ceiling, with different types profile, a special result is obtained. For example, when using an invisible profile (profile for the harpoon and glazing bead methods), the gaps that remain between the wall and the canvas should be additionally masked using a plinth or decorative tape. If you attach a visible profile (clothes-pin profile), you should be very careful not to damage it, because it also acts as a decorative plinth. You should be careful with the corners when cutting, because the appearance of the stretch ceiling depends on this.

Profile installation

First of all, you should first prepare for installing the baguette and tension fabric:

Fig.1. Attaching the baguette to the wall

It is necessary to clear the room of furniture, plants and other objects. There should be nothing at a distance of 1 meter from the wall, as this will interfere with the installation. If some furniture or other interior items cannot be removed from the room, they should be covered with protective material.
To speed up the installation process, you should drill holes in the profile or purchase one already. Remember that a plastic baguette is drilled into a square edge, and a metal one into a panel.
Next, you should mark a line along the perimeter of the room along which the profile will be aligned. This must be done using a level.

Before starting the installation, it doesn’t hurt to look around the room and find out in which places there is a large concentration of wires, a loose wall, and so on.

Sawing corners on baguette

You should start installing the profile from the most inaccessible corner; for this you need to cut out the internal and external corners of the baguette suspended ceilings:

Fig.2. I cut down a baguette to mount the ceiling in the corner

Turn and rest the profile with its back side against the wall and draw a line on the profile at a distance of 1 cm from the corner. Then carefully make a notch back wall profile, without damaging the front wall of the baguette, carefully bend it into the shape of a corner - the inner corner is ready.
To make the outer corners of a stretch ceiling baguette, you need to attach the profile to the wall, and draw a straight line at a distance of 2 cm from the corner; the first notch will be at this place. Then, at the junction of the baguette with the corner of the wall, you also need to draw a line, so that these two marks will be parallel, and located at a distance of 2 cm from each other. Now you need to cut out this part and carefully remove it with pliers, then bend the profile - the outer corner is ready.
Using a baguette on curved sections of the wall, on the back side of the profile you need to make several parallel cuts at the same distance and carefully bend them into the required form. A lip cap should be installed on the sawed-down part of the profile.
After installing the baguette in the corners of the room, you should stick tape on the joints, thus treating them. It is most convenient to make cuts with a hacksaw.

Fig.3. Cutting down the inner corner for installing a stretch ceiling

On a loose wall surface, you need to screw several screws into one section of the profile, thus increasing the strength of the fastening. As an option to solve this problem, you can strengthen the baguette with corners or place emphasis on it. To prevent condensation from appearing between the fixed ceiling and the suspended ceiling, you need to drill holes in the profile that will serve as ventilation. On curved sections of the wall, it is most convenient to use a plastic molding, because it not only bends well, but also fits tightly to the wall. If you are not confident in your abilities and are worried that you will not be able to handle the installation of the profile, then it is better to entrust this matter to professionals. They will do everything smoothly and efficiently, and you don’t have to worry about the fact that the outer corners of the suspended ceiling molding will turn out sloppy, and the canvas will sag over time. The main thing is not to skimp on craftsman and materials, but to give preference to a company that has been providing its products and services for many years.

– this is the shortest and seemingly simplest stage of repair. But probably many of you had to spend at least an hour trying to cut these 45 degrees. The only exceptions are the lucky ones with a technical mindset and those who were friends with geometry at school.

Today we will tell you how to cut the corner of a ceiling and floor plinth without resorting to complex calculations. You will see that this is not at all difficult work, which can be dealt with in a short time.

How to properly cut a ceiling plinth at an angle of 45°

The corner elements for the ceiling plinth can be easily trimmed using a miter box or by hand. In the first case, you will need a miter box and a hacksaw, and in the second, a pencil and a hacksaw/cardboard knife. The hacksaw blade should be well sharpened so that you don’t have to think about how to cover up chips and roughness on the cut.

Cutting a corner using a miter box

We take a polyurethane ceiling plinth designed for the left or right side of the corner. We lean it against the future installation location so that the end of the segment opposite from the corner is against the edge of the already glued molding. In the place where the bottom edge of the ceiling plinth touches the top of the wall corner, make a dot with a pencil or stick a piece of insulating tape. We repeat these steps with the second segment.

How to cut an external corner of a ceiling plinth:

We place the left blank in the miter box from left to right, pressing it to the edge closest to us. The corner vertex mark should coincide with the leftmost slot in the same edge

We place the right blank from right to left, pressing it to the near edge. The mark for the top of the corner is to the far right slot.

How to saw down a ceiling plinth at an internal corner? Everything is very simple, the actions will be exactly the same, only the location of the corner vertex mark changes. Here it’s the other way around: for the left segment – the far right slot, and for the right – the far left. Ready ceiling fillets you need to align them, and then look at the joints in the light - there should be no gaps. If they are very small, then editing is not necessary; you can get by with sealing with putty material after installation.

How to make a corner of a ceiling plinth: positioning the workpiece in a miter box

Important: sometimes the angles deviate too much from the standard 45 degrees, and a simple miter box for the ceiling plinth becomes useless - you can cut off the excess. The solution would be to purchase a rotary tool, but it is not cheap and this “one-time” purchase will be irrational. In this case, you can use the intersecting point method.

How to cut the corners of a ceiling plinth without a miter box

If you are wondering how to properly cut down a ceiling plinth without a miter box, then the following information will be useful to you. We take the right section of the ceiling plinth made of foam plastic, apply it to the installation site and draw a line on the ceiling along its upper edge. It should extend beyond the vertices of the corners by about 5 cm. We do the same with the left segment and put points at the intersections of the lines. We place the ceiling plinths in place one by one and transfer the resulting marks to them.

WITH top part We've sorted out the ceiling moldings, now let's move on to the bottom. Everything is simple here, the marks we need are the vertices of the corners. We mark their location with dots on the lower edges of the left and right ceiling plinth. Next, you need to connect the dots on the moldings - this will be the cutting line. This method will help you cope with even the crooked corners. Adjustment will most likely not be needed, and if it is, it will be minimal.

How to cut a ceiling plinth without special device: marks for the intersecting point method are visible in the photo

Important: The work described here requires marking of surfaces. Therefore, first you need to start cutting and fitting the ceiling plinth, and only then think about how to glue the wallpaper. Or, if you want to mount the plinth on top of the wallpaper, mark and trim before finishing, and gluing after it.

We trim the internal and external corners of the floor skirting boards

It is no more difficult to trim floor moldings evenly than it is to trim ceiling moldings. We only select the cutting tool according to the material that we will cut. The work itself will also be similar, only for manual cutting there is a slightly different marking method.

Cutting wood floor molding using a miter box

It is necessary to measure the distance from the edge of the baseboard already glued to the wall to the top of the corner of the wall. Now we take a new piece of molding and set aside a length equal to this distance on its lower edge. We put a dot with a pencil or stick a piece of electrical tape. We perform this procedure for both external and internal corners. In the miter box we place the plinth pieces from left to right for the left side of the corner and from right to left for the right. In this case, they should be pressed as in the figure - to the side of the miter box closest to you.

How to cut a corner of a ceiling plinth - placing the workpiece in a miter box:

For the outer left one, match the mark on the plinth with the leftmost slot. For the outer right - from the far right.
For the inner left one, we match the mark on the plinth with the rightmost slot. For the inner right - from the extreme left.

Clarification: the slot refers to the one that is on the side that is closest to you.

Cutting the plinth at an angle: the red line marks the place of the cut

Floor plinth: internal and external corner “by hand”

Floor moldings are usually quite wide and thick, and therefore, finding only two points here, as for ceiling moldings, is not enough. To trim an internal corner, first place a point at its top at a height equal to the width of the plinth - in the figure this is a green point. From it to the left and right we set aside a distance equal to the thickness of the plinth - points 1 and 2.

We apply the left segment to the wall, and from point 1 we draw a line along it, perpendicular to the wall and put a point on the edge. We repeat the action with the right segment, only draw from point 2. In the figure, the point is marked with the number three. From it across the baseboard we draw a line to its opposite edge - we get point 4. Now we connect the green point with points 3 and 4 - we get a line and an angle along which the molding can be cut.

How to cut a plinth: make the necessary marks in the corners

Important: It is easier to trim external corners than internal ones. We set points on the left and right segments: A – mark of the top of the corner of the wall; C – the point of intersection of the lines, which is obtained by alternately drawing the left and right sections of the plinth along the floor; B – from point C across the molding a line is drawn to its opposite edge.

By connecting these points with one line, we get a line along which the cut will be made.

Selecting a tool for forming an angle

The most economical option is to buy a simple plastic miter box. It is a plastic block with eight working slots. This device is designed for only two operations: trimming at 45, 90 and 22.5 degrees. An angle of 90 degrees is useful, for example, if you need to embed a socket box into the middle of the molding.

Some devices come with eccentric locks included. They are preferable because it is easier to work with - the plinth is clamped in the desired position and does not move during the cutting process. Accordingly, if any errors occur, they will be minimal and adjusting the angle will not be difficult.

How to cut a plastic baseboard: a simple plastic miter box

If you have to make repairs in your own home, then perhaps it makes sense to purchase a more serious tool - a rotary single-plane miter box. It is designed for cutting at angles of 15, 22.5, 30, 36, 45 and 90 degrees. The design of this miter box includes 2 clamps - for clamping in horizontal and vertical planes, as well as a limiter that will allow you to cut workpieces to the same length. The hacksaw will be built-in here. If it is not clear how to cut a ceiling plinth, the video review below will help you.

This will be useful to you in your work

As you may have noticed, the text mentioned making marks using duct tape. This is the most convenient way marking workpieces, since the pencil is not always visible on floor plinth, and sometimes it’s difficult to remove its lines from the ceiling. The bright pieces of electrical tape are very clearly visible, and when they are no longer needed, they are removed literally with one movement of the hand. There are no traces of glue left after removing such marks.

Sometimes you have to trim moldings with very large drawing. How to connect corners to make them beautiful:

From one long fillet we cut pieces according to the number of corners, each of which should contain an element of the pattern. On both sides of the pattern there should be 5 cm of the length of the plinth.
We measure the resulting blanks and find their middle, cut along the center line.
We make corner trims as usual, but taking into account the fact that the centers of the patterns on the workpieces should fall on the tops of the corners.
