Fixing overhead wooden corners on the corners. How to glue a corner: simple secrets

How to glue an arched corner with your own hands

The topic of today's article is an arched corner. We will talk about the types, purpose and methods of fastening this finishing element.

To begin with, let's define the terminology: which of them are called arched and what is their difference. In general, such angles serve to design curvilinear structures from various types of finishing and building materials.

The main purpose of these elements is to protect the decorative coating of corners. They prevent peeling and abrasion of paint, wallpaper, etc. Also, these corners, as it were, highlight the shape of the structures they are attached to. For example, arches (see), plasterboard niches, curly ceilings.

Decorative

Arched PVC element

So:

• The decorative element has a different width on each side. For example, 20 × 10mm or 20 × 5mm. From the very name of this corner, it is clear that it serves to decorate arches and highlight them against the background of the general interior in the room.
• In addition to the design function, this type of finish allows you to hide small irregularities on the arched openings. This is especially true when the arches are made by hand. For example, from drywall (see).
• And, of course, such a decor protects the finish coating of the walls from various types of influences: wallpaper from abrasion, putty and VD-paint from delamination and chipping from the surface of the corners.
• Decorative corners with a length of 2 meters 70 centimeters are produced. They have different colors: white, wood-like (repeating its structure), colored.
• The main material for the manufacture is polyvinyl chloride. It is the arched pvc corner that has received the greatest distribution among finishers. It is also possible to find cork corners for arches on sale in stores.

So:

• This type of auxiliary finishing materials has perforations (holes) on its entire surface. One side has petals (similar to cuts). Thanks to this design, they bend perfectly.
• Basically, the perforated arched element under consideration is used to give a smooth edge to curved structures. For example, when installing plasterboard arches, figured suspended ceilings, graceful partitions. It is not difficult to bend it, because it is very flexible.
• Corners for plaster are made of plastic. The most common length is 3 meters.

Fastening

Fastening decorative elements

If you decide to abandon the installation of an interior door and made a semicircular opening (see), then you need to “ennoble” it - attach an arched decorative corner around the entire contour.

There are several ways to do this:

• Stick with glue.
• Fasten with screws.
• Pin with carnations without hats.

Let's take a closer look at each of these methods. Most often, PVC elements are glued to the wall with glue. For example, liquid nails or titanium.

Should know! No need to use liquid nails for heavy structures! They may contain solvents that can corrode plastic. The best option is Express-Decor class glue.

Before you start gluing the corners to the surface, it should be prepared:

Should know! In no case do not stick plastic corners on the wallpaper. Even if the latter are firmly attached to the wall.

• All loose materials must be removed.
• If you already have wallpaper pasted, then remove it from the place where the corner will be pasted as follows: attach it tightly to the “native” place and mark its edge on both sides with a pencil. Then remove and carefully cut and remove the wallpaper with a sharp clerical knife.

Now you can start gluing. If you decide to use liquid nails, then it is better to take them in a tube (for a gun). From such packaging it will be more convenient to apply glue. Just buy the gun itself.

Apply glue in a small layer along the entire length and attach to the wall. Move the corner a little so that the glue spreads over the surface. Then remove the corner and wait five minutes. After that, firmly press the element again and fix it to the wall with masking tape.

External corners must be aligned and reinforced during the repair process, for which it is necessary to use a perforated corner of various sections. Today we will talk about fixing a perforated painting corner on an external plaster or plasterboard corner, as well as clarify the work steps and the materials necessary for this.

Materials and tools

The corner has a central stiffener and side strips with perforations, which helps the element to be securely fixed on the edges of the outer corner. You can fix the corner on gypsum plaster or starting putty, as a rule, a putty mixture is used to fix it on drywall, and a gypsum plaster composition is used to fix it to plaster. External corners are not only vertical corners at the junction of two walls, but also sections of plasterboard ceiling structures, as well as window and door slopes.

Instruction

To work, in addition to the corner and the material, you will need metal scissors, a spatula and a level. First, the perforated element is cut at an acute angle with the edges with scissors, then a small amount of Rothband or Start putty is kneaded and installation begins.

When fixing to the corner of the GKL, a minimum amount of putty is required, it is applied with a spatula along the edges of the outer corner, the corner is applied to the base and pressed tightly. The remains of the mixture that have made their way through the perforation are removed. In this case, you can do without a level, because the plasterboards are attached evenly and there is no point in doing the same job twice. With perfectly even corners of the GKL structures, the corner is fixed with a stapler.

When attaching the corner to the plaster, most often the corner must be trimmed, so the gypsum mixture is applied with strokes of greater thickness, the corner is applied without pressure and only then is pressed with a level until it is completely aligned vertically. Since in some places of the outer corner the corner protrudes above the surface of the side walls by 3-4, and sometimes by 5-7 mm, after fixing the element of the pit on the wall, it is necessary to close it with a gypsum mixture using a spatula wide from 40 cm.

Putty and plaster for fixing the corner should be kneaded only in a plastic bucket, first pouring water into it and then adding the dry mixture and kneading it with a mixer. The consistency of the mixture is from "thick sour cream" for gypsum boards and gypsum boards to liquid plasticine for plaster corners with large differences.

Conclusion

In conclusion, we note that in addition to painting, there are plaster corners, which instead of perforation have a rigid mesh on the sides, they are used only in plaster work, fixing directly into the body of the solution at the corner and plastic elements for curved corners.

Below you can find a video on attaching a perforated corner.

When the doors and windows are installed, you need to finish the slopes, as a rule, this is the final stage. To hide small roughness and give a complete aesthetic look, many use ready-made corners. How to cut and glue a corner of plastic, cork or MDF? Below are detailed instructions for their installation.

Let's start with the most important - why is it necessary? What role do the corners play - only decorative or do they have more serious functions? We will not argue with the fact that if you frame the slopes of doors or windows with special decorative elements that fit perfectly into the design of the room, then the interior will immediately change for the better.

Corners protect slopes from damage

But besides this, they also perform a very important protective function. Sooner or later, you have to carry large items through the opening, which is fraught with damage to the corners, and you can simply accidentally touch the outer corner and damage it. There can be a lot of situations, most importantly, the result is the same - a damaged surface and, accordingly, a look. In addition, as practice shows, most often the wallpaper begins to peel off in these places. So it is best to protect the outer corner of the slope with a decorative element, which will also transform the interior.

Corners are not only protection, but also a neat aesthetic appearance

Plastic, wooden or MDF - which one to choose?

Convinced that the installation of corners is not just a whim, but a necessity, we will study the construction market in order to make the right choice. These products are divided into types depending on the material from which they are made. So, the corner can be plastic, wooden, bamboo, made of cork or MDF. Absolutely each type has its pros and cons, we will consider them in more detail.

To trim the corner, use a hacksaw with fine teeth.

How to glue

Finally, we got to the main question, how to stick the corners on the slopes. However, before proceeding directly to fixing, it is necessary to carry out, so to speak, a fitting. After making sure that everything is trimmed correctly, you can move on. We apply an adhesive solution in increments of approximately 10 cm to the inside of the corner, at the junction of the sides. At this stage, the mounting 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 slopes. We remove excess sealant from the surface of the walls with a damp cloth and let it dry thoroughly. The tape can only be removed after 24 hours.

Having dealt with what such products are made of, what are their features and having decided on the choice, you should learn how to install the corners on the slopes. Detailed instructions are given below.

Finishing the corners in the apartment should be resorted to in cases where small children grow up in the family or animals are kept. Since stucco finishing mixtures do not have great strength, they are destroyed by light impact on them.

Especially often external corners are destroyed. Dents often appear on the corners pasted over with wallpaper, notches appear on the painted corners.

To protect the corners, the use of special devices and techniques that protect the corners from destruction is required.

We note right away that the process of finishing the corners in an apartment is a difficult and crucial stage. It is much easier to get a flat surface than to align the corners. Next, consider ways to protect the corners of the walls in the apartment and house from damage.

When do you need to trim corners?

Finishing the corners in the apartment is advisable in cases of installation in the corners of rectangular furniture. Aligning the corners eliminates distortions, allows you to harmoniously place rectangular furniture.

With large distortions, you should not resort to leveling the corners, since when leveling, the usable area of ​​\u200b\u200bthe room decreases, but it is possible to beat with a stone.

Which material is best for corner protection

In any room, corners are divided into internal and external.
And if it is difficult to get to the inner corners, then the outer corners suffer more often, and not only from the careless carrying of heavy household appliances or furniture.
Animals scratch the corners, and they often block the way for children.
For finishing corners, plastic, metal, polystyrene foam, wooden corners, special galvanized metal profiles, and decorative stone are most often used.
Plastic corners have an extensive range of colors. They have increased softness, varying degrees of roughness.

To the question: “How to finish the corners of the walls in the apartment?”, The article below will best answer.

Consider all the materials and fixtures used to protect the corners of the walls.
Materials mean the use of drywall, and as fixtures, the use of metal, wooden, polystyrene foam corners, PVC corners.

Aligning corners is one of the most difficult stages of finishing a room, requiring theoretical knowledge and extensive practical experience.

The protection of the corners of the walls is carried out by installing special devices. Corners made of different materials are most often used as protection for wall corners.

Most often, PVC corners are installed as corner protection.

Plastic corners should be installed after all finishing work has been completed.

Plastic corners are installed on the walls using a mounting adhesive for plastic products.

Plastic corners are produced with a length of 2.5 m. The width of the corners is different, from narrow to wide.

To choose the right corners in width, you should measure the curvature of the corner.

With large curvature, it is preferable to choose corners of greater width.

Narrow corners are used at almost flat corners

How to fix plastic corners on the corners of the walls?

Option 1

• 1. With the help of a construction angle, it is necessary to measure the deviations of the angle.
  2. Knead the desired consistency of the solution from the dry putty mixture.
  3. Apply the solution with an ordinary spatula, level it with an angled one, giving the corner a rectangular look.
  4. After the corner has completely dried, attach a plastic perforated corner and close it with a finishing putty.
  5.When the layer is completely dry, sand the surface with an abrasive mesh.

Option 2

The most common and inexpensive way is to use plastic corners of various sizes and colors. when choosing, pay attention to the correct angle, the fit to the wall depends on it.

Types and sizes of PVC corners

• 1.Plastic corners are installed on a previously prepared surface. If necessary, remove the old wallpaper with a drywall knife, clean the surface of the old paint.
  2. Apply glue to the inner surface of the corner in increments of 30 ... 50 mm. Glue is applied dotted.
  3. When the adhesive reaches the desired viscosity (indicated in the instructions for the adhesive), attach the plastic corner to the corner to be protected and fix it on top with masking tape.
  4. In place of liquid nails, it is possible to use colorless silicone.

These options for wall corner protection are also suitable when using metal profile corners.

If you want not only to protect the corners, but also to decorate the corners in the apartment, use wooden or polystyrene foam corners.


Styrofoam corners
Expanded polystyrene is a non-combustible material.

Styrofoam corners do not absorb moisture, dirt does not stick to them. Polystyrene corners can be used in rooms with any temperature conditions.

The surface of polystyrene corners can be painted. The profile of the corners is created by pressing and is available in various shapes.

Finishing the outer corners in the apartment with the help of polystyrene foam corners is justified in those rooms where there is little traffic for residents.

Decorative corners made of expanded polystyrene allow not only to protect the corners, but also to perform a decorative design of the corners.

Fastening is possible both on special glue and on ordinary acrylic sealant.

Wooden corners
The main advantages of wooden corners are:

• attractive appearance;
• environmental friendliness;
• the possibility of creating a carving or decoration.

Wooden corners are an indispensable material for decorating corners in an apartment.
Not the best option to use wooden corners in rooms with high humidity;

Stone as a decorative element
Recently, the use of stone in interior decoration has become fashionable. The decorative design with stone looks especially organic when protecting external corners.


The use of stone is especially appropriate when the outer corners have large deviations from the geometric shape. There is no need to level walls and corners.

Let's note right away! It is better to use a decorative stone. It is also lighter than natural. And having a smooth surface makes maintenance much easier.

The stone is fixed with a special mortar or tile adhesive.

Step 1

Before laying decorative stone, the surface should be prepared,
remove dirt, dust, old coatings and
If the surface is very dry, or you work at a temperature of +30C and above, it must be moistened.
This is necessary for better penetration of the adhesive into the depth of the prepared surface.

Step 2
Glue is diluted according to the attached instructions in quantities that you can use during work. Properties of glue remain within 2 hours.

Step 3
It is best to prepare glue in a plastic container using a drill with a mixer attachment. After mixing, the adhesive is kept for several minutes and thoroughly mixed.

Step 4
On the back side of the stone, the solution is applied with a spatula, the edges of the tile are coated with the solution. Several mortar cakes are applied to the surface of the wall and a stone is applied.

Step 5
The stone is pressed against the surface with force, it is checked by a plumb line and the level of the correctness of its installation.

Step 6
After laying the stone in three rows, stop work. The adhesive is fully cured after two hours. This will allow you to continue laying the next 3 rows.

Failure to comply with the requirements of step 6 will lead to the collapse of the structure under its own weight.

Drywall for finishing corners
The use of plasterboard sheets GKL allows you to align any, the most crooked corners.
There are two ways to install drywall sheets: frameless, frame.


Method 1
Frameless installation of drywall sheets is used on both internal and external corners:

• surface preparation is carried out;
• a drywall sheet is applied to the surface and marked;
• on the other side of the corner, a sheet is also applied and marked;
• blanks are cut with a knife and cuts are made with a planer at the mating corners of drywall;
• prepared blanks of drywall sheets are again applied to the corner and adjusted;
• mounting foam is applied to the sheets;
• both blanks are applied to the wall and pressed;
• sheets are removed, leaving traces of mounting foam on the wall;
• polyurethane foam is reapplied to the sheets;
• the foam should be allowed to dry a little and attach the sheets in place;
• it remains to correct the angle using a wooden rail or building level.

Method 2
The frame method is recommended for use in cases of significant surface curvature.
This method is more laborious, but it can significantly improve sound and heat insulation:

• it is necessary to measure the deviation of the angle;
• install the frame using galvanized metal profiles, securing them with dowels, self-tapping screws;
• a plasterboard sheet is installed on the frame and fastened with self-tapping screws;
• the resulting surface is puttied, polished;
• the corner is protected by a perforated mesh.

So you have finished finishing the walls with drywall. But one very important detail remained - the corners. In this article, we will figure out how to make the corners of drywall walls even and how to fix the corner to drywall. And also which corners to use is better, easier and cheaper.

Types of corners and why they are needed

Perforated drywall corners not only allow you to beautifully seal the corner joint, but also give even greater structural strength, preventing even slight movements and vibrations from the plasterboard sheets.

On sale you can find 4 types of corners. There are perforated corners for right angles and even arched models. So:

• Perforated metal corner

This is the most famous and used model. The thin perforated metal construction has a rib to provide rigidity. But, despite this, the configuration of the corner is often violated during transportation, which makes it impossible to use it to create perfectly even corners. Therefore, the store always needs to check their quality.

• Plastic corners

The material is the main difference from the previous version. This results in low strength and low resistance to shape change. Advantages - not afraid of water and moisture, corrosion is not terrible. A big plus is the low price.

• arched corners

Everything is clear from the name - it has the ability to bend well. This is the main advantage over other types. The material from which it is made - flexible plastic - gives it such an opportunity.

• Mesh corners

They are usually used where it is necessary to protect the corner from mechanical damage and give additional rigidity. Often such places are the outer corners of buildings. But we use them in the apartment. This will be useful if the corners are rather uneven and of dubious strength.

We examined the main corners of drywall, which is better - you decide. You should choose based on where the perforated corner will be installed on drywall and what goal will be pursued: will it be a significant strengthening of the corner or just a design idea. Also pay attention to the price.

Important: if you just need to fasten the sheets at an angle of 90 degrees, you need not a corner, but a connector. This frame element does not apply to corners.

How to attach a perforated corner to drywall?

For work, we need some tools and materials:

• The corner itself
• Putty. It is she who will ensure reliable fastening of the corner to drywall (the best composition for this work is Vetonit, it is reliable and easy to use)
• A primer with which we will strengthen the GKL sheets, and then we will carry out the final processing
• Scissors for working with metal (if you are going to fix not a plastic corner on drywall, but a metal one)
• Brush for priming surfaces
• Two spatulas: one wide, the other narrow (wide is more convenient to smooth out irregularities on the surface, and narrow to apply the composition and distribute it)
• Bar for grinding. It will help to make perfectly even corners, removing all irregularities

Now let's figure out in detail how to fix the corner on drywall:

1. We carry out the primer of each sheet of the corner, drawing a strip of about 30 cm. After that, we take measurements in order to know how much the length of the corner is required. A distance of 20-30 mm to the floor can be left without a corner, since everything will be closed with a plinth anyway;
2. According to the results of measurements, we cut a corner. Having made cuts, the metal corner can be easily and accurately broken;
3. With a narrow spatula, apply putty to the joint itself. The layer thickness is small (about 3-4 mm);
4. We press the corner so that the putty penetrates through the perforation outward;
5. Apply a thicker layer of putty on top;
6. We level everything with a wide spatula and remove excesses, while holding the tool at an angle to the sheet and pressing it a little;
7. We grind the corner with a bar;
8. Then we apply a second coat of primer. The width of the strips should be 20-30 cm. This method allows you to remove a sharp transition between the layer and the plasterboard wall;
9. Now we finally align the angle: first with a spatula, and then, already on dry putty, with a bar;
10. Before plastering the rest of the wall, apply an additional coat of primer to the joint.
