What glue to use

In addition to the corners themselves, we also need an adhesive composition with which we will fix the selected element. When choosing it, it is worth remembering that quite often, especially if it is necessary to glue a narrow product, the glue seeps out from under it and, naturally, falls on the walls. As a result of this, the latter can be damaged, which, accordingly, will negatively affect the appearance of the room as a whole. Therefore, you should choose such an adhesive composition, the excess of which can be removed from the surface.

Basically, the corners are glued to new slopes, but nevertheless, check that the surface is relatively flat, since no decoration can hide large bumps. It should be free of foreign objects such as nails, self-tapping screws, etc. It also needs to be degreased, for this purpose white spirit is suitable.

These products are divided into types depending on the material from which they are made. So, the corner can be plastic, wood, bamboo, made of cork, or Fiberboard. Absolutely each type has its pros and cons, we will consider them in more detail.

Plastic corners are made by hot folding a sheet of polyvinyl chloride. Basically, they have the same shelf width. from 10 to 40 mm in 5 mm increments. However, there are asymmetric specimens, for example, 10×25 mm, but regardless of this parameter, the angle between the sides is 90 degrees. If it is necessary to transform the arched opening, then this is done by means of a special flexible profile. Their advantages can be called a relatively low cost, they do not need painting, unlike the same tree.

The next type is cork corners. Such decorative elements are quite often used for arched openings, but this does not mean at all that their use is limited only to this area. They can also be used for finishing slopes of various shapes. The cork has a number of advantages, including strength, fire resistance, practicality and environmental friendliness. In principle, this material has practically no drawbacks, except that if your pet wants to sharpen its claws on it, this will damage the surface.

It is also worth noting wooden and bamboo products, which will always be signs of excellent taste and will fit into almost any interior. In addition, we must not forget about their environmental friendliness. True, such elements are somewhat more expensive than their counterparts made from other materials, and besides, they often need painting. A material such as Fiberboard can also be compared with natural wood, only it costs significantly lower, because wood dust is used to create it.

The best way to do this is with a fine-toothed hacksaw. First, you need to measure the length of the opening, then we put marks on the corner itself so that the segment corresponds to this parameter. Then we cut off the part that will adjoin directly to the slope strictly according to the marks, and the part that will be against the wall at an angle of 45 °.

  • Before you glue all the details, you should use the advice: it is better to measure the corners for the slopes of doors and plastic windows locally. First place the top horizontal element, and then use the cutting tool to mark the vertical stripes.

Important! Using photos and videos, each beginner will cope with the gluing process on their own. The metal element is also fixed with self-tapping screws.

Sheathing with corners also implies additional fastening of the strips using narrow masking tape. Fix the strip with it in several places and leave it for about 24 hours. This time is enough to reliably glue the corners to the surface.

If the corner is used as a finishing finish, then the place of its gluing should be cleaned of finishing materials. Thus, the grip quality is increased. When fixing on an area decorated with trellises, a strip should be cut a couple of millimeters wide than the plastic corners.

To fix the plastic skirting board to the ceiling, you need to additionally prepare the surface. The ceiling is leveled with a primer, cleaned and only then proceed to gluing.

A strip of the required length is cut from the panel and glued with a putty with PVA or polymer glue. After installing the corner, the joints are sealed with putty and leveled with sandpaper.

You can arrange the joints and corners in the house yourself, even without the skills of a builder. I hope the presented material is enough to properly glue the corner in any situation. The following video will help the perception of the stated.

Carrying out the lathing

To create a high-quality cladding, you need to use wooden slats with a total cross section of 2020 millimeters, which are mounted on the far corner of the slope from above, as well as from the sides with dowels with a step of 30 centimeters. The lathing must be completely flat, for this, using a planer, the thickness of the wooden slats is equal and its indicator is checked using the building level.

Scope of application

Most often, a tile window sill is made in houses of brick, ceramic concrete, foam concrete or cinder blocks. In these houses, the window sill, as a rule, is already filled in or a kind of blank has been made, which will serve as its base. It must be thoroughly cleaned of dust and primed to increase the adhesion of the material to the substrate. If this is not done, the tiles may fly off after a few months.

How to plaster the slopes of doorways and window frames

Frame plating method

In order for the elements of the future frame to adhere more tightly to the wall, it is imperative to level the surface, and then prime it, otherwise it may crumble.

For the frame, you will need a profile used for drywall, or wooden bars, slats. Dowels are used to secure them. Along the entire opening of the entrance door, it is fastened along a pair of slats parallel to each other. For reliability, jumpers are placed.

Each type of facing material has its own characteristics of installation on the frame.

Fastening the guide profile

To begin with, the profile along the outer edge is measured using a construction tape, and after it the outer width and total distance from the upper edge of the window structure to the window sill. Further, a U-shaped profile of the required width is taken, cut into several segments using special metal scissors according to the measurement performed. After that, the pieces of the part are screwed with a total gap of 20 centimeters using screws along the outer part of the window. The fastening of the top and side profiles takes place in the same way.

Finishing the slopes of the entrance door

  • In this version of cladding, finishing sheets, for example, Fiberboard, are attached to the leveled surface with quality glue or cement mortar. The adhesive and fixing mortar must match the veneering material.
  • Glue or mortar is applied to surfaces in contact with each other, then the cladding panels are gently pressed against the slope.
  • The level should check the correct installation of the finishing sheets. This must be done immediately after work, until the solution has hardened.

What glue to use

In addition to the corners themselves, we also need an adhesive composition with which we will fix the selected element. When choosing it, it is worth remembering that quite often, especially if it is necessary to glue a narrow product, the glue seeps out from under it and, naturally, falls on the walls. As a result of this, the latter can be damaged, which, accordingly, will negatively affect the appearance of the room as a whole.

How to properly cut corners for windows

Plastic (PVC) corners are very widely used in interior decoration, they are installed on the slopes of plastic windows, they frame the outer corners of the walls and the slopes of doorways. In this article, we will take a closer look at the process of installing a PVC corner on the slope of a plastic window, and also consider how to make a neat joint between two corners.

Step 1. Making the markup. We need to attach a PVC corner to the slope and mark the edge of the vertical slope:

The minimum length of the applied angle (L) must be greater than the height of the slope (a) by the width of the angle (b), taking into account a small margin (c):

For example, if the height of the slope is a = 1500 mm and the width of the corner is b = 30 mm, then the length of the corner must be at least a b c = 1500 30 15 = 1545 mm.

Step 2. Make a cutout on the PVC corner, removing one edge, as shown in the photo below:

The corner fits perfectly, you can proceed to the next step.

Step 3. The plastic corner is glued only to the slope, this is enough for fixing, so we apply glue only on one of the edges.

As glue, you can use “Moment Montage”, “QUELYD Masterfix” and their analogues. It is not recommended to use super glue, as it will be almost impossible to correct mistakes.

Glue is applied to the inner surface of the corner in a dotted manner or in a thin strip:

We fix the PVC corner with masking tape (while the glue dries):

Step 4. Repeat step 1-3 for the right slope:

Step 5. We mount the corner on a horizontal slope. The length of the corner is taken with the same margin as for the vertical one, but taking into account both sides. Marking is also performed, and then cutouts are made and the corner is glued to the slope:

Step 6. Mark the place of the cut. The corners will mate at a 45 ° angle:

How to glue

Finally, we got to the main question, how to stick the corners on the slopes. However, before proceeding directly to fixation, you should carry out, so to speak, fitting. After making sure that everything is cut correctly, you can move on. We apply an adhesive solution on the inside of the corner, at the junction of the sides, with a step of approximately 10 cm. At this stage, an assembly gun will be an indispensable assistant. After that, quickly press the product to the surface and fix it in this position with masking tape. You should start with a horizontal slope, and then proceed to the side ones. We remove excess sealant from the surface of the walls with a damp cloth and let it dry thoroughly. You can remove the tape only after 24 hours.

Features of the

To give the inner corners of window and door openings the desired and neat shape, special plastic corners are installed for the slopes. This finishing material is part of the decoration and is needed to hide the corner gaps that arise when using materials of different textures. The corners are assembled at the final stage of the renovation and completely transform the decoration of the windows and doors. They not only add a graceful touch to the overall atmosphere of the house, but also create a protective function.

Corner parts for slopes are made by hot bending PVC sheets using a special technology, due to which they become strong and durable.

They are used in various home decorating jobs and are necessary for:

  • facing of window and door slopes, arched openings inside the apartment;
  • protection of corner wall panels when plastering or wallpapering;
  • when laying tiles.

PVC corners have many advantages:

  • they can close the gaps of any materials at an angle of 90 degrees;
  • can be used for a long time (service life. up to 25 years) and at the same time do not lose their basic properties;
  • easy installation using glue, which can be done on your own, subject to the correct calculation of the cutting;
  • plastic material, convenient for cutting;
  • relatively low cost;
  • insignificant mass that does not load the slopes;
  • do not require additional painting and processing;
  • protect corners from wallpaper wear;
  • do not give in to the influence of ultraviolet radiation, therefore they do not fade and can be used for a long time;
  • thanks to the huge number of colors and shapes, they perfectly match any interior and add integrity to the entire design of the room.

The disadvantages include some fragility of the material, so you need to cut it carefully and with special tools. Also, the corners do not tolerate high temperatures and, when ignited, emit toxic gas, which negatively affects the state of human health.

Manufacturers offer various types of PVC plastic corners in accordance with the size and scope.

  • Standard, or P-profile. It is used to strengthen window and door slopes, and it is recommended to install it at the initial stage of installation of slopes. The purpose of this profile is to decorate and protect the outer corners from deformation. It also helps to hide gaps between coatings, which do not connect very tightly.
  • Versatile, or L-profile. It is used when installed on curly or arched openings. Such a profile is a flexible angle, the flanges of which converge at an angle of 90 degrees. Very easy to mount, because when bent, it keeps the desired position for installation well.
  • F-shaped. It can be easily attached to the end sides of the panels, even without glue, since it has a special jumper. Unlike other types, such a profile can be easily removed while painting walls or gluing wallpaper. The main purpose of this piece is to hide the gaps between the wall panels, as well as the decor of the openings. In addition, it acts as a platband, which frames a door or window along the perimeter.
  • T-profile. It is used if you want to achieve an ideal joint boundary between the slope and the panels. It flawlessly combines various finishing materials, which have different types of texture, and can be easily fixed on any surface. When laying tiles, it hides the unevenness of the tile at the joints with a flat base of the floor.
  • Removable. This type of corner piece has a latch and has increased ductility. It can be easily bent 3–6 mm. It is not necessary to remove them during repairs. you just need to fill the wallpaper with a spatula under the corners. This allows assembly to be carried out much faster.

There is also a self-adhesive version of PVC corners on sale, which is versatile, since you do not need to buy glue separately for it. In addition, it has good flexibility, which makes installation extremely easy. For the convenience of the user, they are often sold in rolls up to 50 meters long, and a part of any desired length can be purchased to avoid seams.

In repair work, plastic perforated corners are also used. Their purpose is to strengthen and protect the inner and outer corners from damage and cracks. Often this type of material is used to give greater strength to protruding joints and level the surface.

By the type of finishing processes, internal and external PVC corners are distinguished. In turn, the outside angle can be 90 or 105 degrees. The 90-degree corner is attached so that only one side of the edging is visible, and the 105-degree corner is mounted with both shelves up.

By their structure, the products are divided into a rigid structure and a soft, or flexible, folding profile. The rigid structure is a classic rectangular profile, both shelves of which are formed into one piece. Such products are used when making corners where you need to make a bend of 90 degrees.

To embody the final image of the interior, white or colored decorative details are used that fit the overall design of the room.

All parts are manufactured in accordance with the standards of Building Codes and Rules (SNiP).

How to install?

When all the finishing work is completed, you can start the process of mounting the plastic corners. It starts with a selection of glue. There are special adhesives on the market that are used to work with PVC parts. The most suitable option is a composition called “liquid nails”. You will also need a clerical knife with replaceable blades, a hacksaw or scissors for cutting metal, a measuring tool, adhesive and masking tape.

Profile mounting is carried out in several stages.

Regardless of where you need to glue the decorating part (on a window, door or arched opening), you first need to take measurements and cut the finishing material correctly.

After that, you should prepare the surface where gluing will be done.

  • it is worth cutting off unnecessary elements that interfere with the fixing of the corner piece: pieces of old finishing material or polyurethane foam, protruding plaster and others;
  • degrease the surface well, otherwise the corner will not adhere well.

Then you need to apply the adhesive directly to the finishing material in a not very thick layer. Press the workpiece tightly, and remove excess glue. Fix the part additionally with paper tape. It needs to be glued in several places and left for a day. It can be removed after 24 hours.

A very convenient in design version of a PVC product. a corner with adhesive tape on the inside. It is enough to remove the film from it, after which you can immediately glue, pressing down along the entire length. It is very important to immediately put the profile correctly, because the second time it can no longer be used.

There are several options for joining inner corners:

  • the areas are superimposed on each other, while the gaps are covered with a hermetic agent or putty to match the material;
  • one of the strips is cut to the base, for example, if the top part is left with 20 mm allowances on each side, then the side strips are cut to the same level with it;
  • trim planks at an angle of 45 degrees.
