How to fix aluminum corner on the wall. How to cut and glue corners on door and window slopes

Corner for drywall 25x25 mm galvanized - one of the types of material that is used to level parts of the walls. As you know, drywall is popular in construction, it is easy to work with. However, prefabricated ones have problem areas - corners, which are most often subject to mechanical stress. This is where various types of existing corners will come to the rescue.

Existing types of drywall corners

They perform a protective function of parts of the walls and will help to build even corners. Knowing their classification, you can choose a suitable instance.

The most common product options are:

Metal perforated corner

This view is a thin sample from a profile with perforation and a rigid edge along the edge. Basically, there are 2 types of similar corners for drywall:

straight;
arched.

These representatives have many subspecies. The corners are not glued, they are practically “fitted” onto the structure and fixed with putty or.

The straight perforated corner is used for processing the inside and outside of the corners.

It is a V-shaped profile with many holes - perforations.

Variants of metal perforated corner for drywall

Actually, with their help, a high-quality connection with the processed corners takes place, and the top, located at the inner corners - inside, and at the outer corners - outside, is a guide for the spatula. Excess air also escapes through the holes. Straight punch angles are plastic, aluminum, galvanized. The latter is tougher than others, and the wide one can generally be used as a plaster beacon.

plastic corner

This sample is more resistant to moisture than from the profile, but the resistance to mechanical damage is lower. Of the advantages, one can note the low price and the absence of corrosion of the material. There is also a type of plastic corner, for example, AquaBead, which has a special paper with glue applied in the inside. Putty for fixing is not required here, it is enough to moisten the adhesive surface with water and simply glue the corner to the right place.

Arched

Various finishing materials are used, such as plaster, wallpaper, panels and others. But in order to preserve the transition points between the planes, an arched corner is used, which has great potential. Arched corners are divided into the following types:

Installed under plaster, perforated. They have separate petals on one side of the corner, allowing you to place a sufficient strip on any arched bend. There are plastic and from the profile;
Decorative, gluing of which occurs on the plaster.

Mesh Products

Similar elements are used in places that require the strengthening of corners and protection from damage. Plaster mesh corners are designed for internal and external corners. They can be either plastic or metal. The choice will be influenced by the shape and material of the plane for finishing.

Mounting corners on drywall using corners

When starting to install a corner on drywall, you need to have tools and material on hand.

Required material

the selected type of corner will need to be bought with some margin;
via ;
it is best to buy Vetonit putty, which is of high quality.

Tools

metal scissors will help to correctly and quickly cut the necessary parts;
brush, which is required for applying the primer;
wide and narrow spatulas will be needed for;
the grinding block will remove all the irregularities on the plane, while the angle will be perfectly even.

This is how the mounted corners on drywall look like

When starting installation, it is necessary to familiarize yourself with the sequence of aligning the corners with putty so as not to damage this fragile material.

Stages of work

First, the plane must be thoroughly cleaned and treated with a primer. You need to proceed to the next stage only after it has completely dried.
Measurements are taken, and the desired length of the corners is cut off. They are applied to drywall as a fitting.
For further work, you will need a non-woven tape, a serpentine mesh for inner corners, one of the types of perforated corners: plastic, adhesive, rounded or from a metal profile or paper-based.
Before you make a choice. For the formation of internal and external corners, it is better to buy a dry gypsum mixture. It has an affordable price, good quality and will be able to securely fix the elements on the structure.
Putty is prepared in compliance with all stages: poured, poured, stirred, allowed to settle, kneaded again.
When working with external corners, it must be remembered that they are most often subjected to mechanical stress, it is better to fasten metal samples, in some cases having a rounded shape.
Check the evenness of the end.
Putty is applied to the treated area with smooth movements. Not allowing the composition to dry out, you need to fix the corner with pressure, check the accuracy with a level, if necessary, you can knock with a rubber mallet.
Sometimes the corner is attached to the drywall with a stapler or glued with glue, and then covered with putty.
Another layer of the mixture is applied to the installed element and now it is aligned with the general plane of the wall.
Applying the second coat of putty
After thorough drying, the sloping corner is polished.
Installing the corners inside the structure looks similar, even a little easier. The adjacent sides, the gap between the corners are carefully smeared with a spatula, and the excess mixture is removed. On a dried polished surface having the desired shape. You can buy and, only put it on raw putty.
check the fastening on the drywall of the corner, then with the help of the next layer hide the irregularities.
After thorough drying, the surface is finished with sandpaper or a polished bar, while forming a perfect angle.
To facilitate the leveling process, so-called beacons are used, attached to the surface with a plaster solution, here you can do without fasteners.
Separately, I would like to mention a semicircular plastic corner used in rooms with the maximum possible impact on the corners. It is made of flexible plastic and has not an acute angle, but a semicircular one. Its price is quite acceptable, and its durability is beyond doubt. It differs in some features at the installation stage, namely, cutting the end by 1.5-2 cm with an angle of 45 ͦ. A corner is pressed into the applied initial putty, fixed with a stapler, the edges are processed with a mixture.

The video of arranging the corners will help you see how the drywall parts are reinforced, and will also allow you to select and buy the necessary elements.

Finishing inside and outside corners will not seem difficult with the right approach and the necessary training. The main thing is that during installation they should be requiring minimal finishing.

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 on the inside of the corner, at the junction of the sides, in increments of approximately 10 cm. 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.

Thus, plastic corners can be placed on the slopes of a window or door. As you can see, there is nothing complicated in this process.

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.

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 mortar body at the corner and plastic elements for curved corners.

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

A plastic plinth with a cable channel is good for everyone! And it is convenient to use, and the wire can be hidden in it, and it looks decent. But even when working with it, incidents may arise that require ingenuity and non-standard solutions from you. And why invent something if this is already a passed stage for some? After reading this material, you will learn how to fix a plastic skirting board with non-standard corners and rounded walls.

If the walls are curved

Recently, more and more such details can be found in the interior of apartments. How to fix the plinth in such a place? If the radius of curvature is large and smooth, then there will be no problems. What if the radius is small and steep enough?

Try this. Use a hacksaw to make cuts on the back of the plinth so that the plastic is not damaged from the outside. Be careful! The sawn plinth may bend to the required circumference. If this does not help, it will be necessary to break it in this area by installing plugs.

An example of mounting a plastic plinth on a rounded wall.

Most likely, this will have to be done. But it will be necessary to fix the plastic plinth in the place of the rounded wall more often than on level ground. Just a few centimeters later, a new fastener!

How to fix a plastic baseboard if the outer angle is more than 90 degrees

Such interior details are also now not uncommon.

An example of installing a skirting board at an outer corner of more than 90 degrees.

The trouble here is that fittings for such corners are not available.

Typically, fittings are represented by four parts; outer right angle, inner right angle, end cap and connector. With an external angle of more than 90 degrees, there can be two options for working.

First

Try to “finish with a file” the fittings for the outer right angle. If you carefully try to trim this part on both sides, then the result can be as in the photo below.

The plastic corner itself will no longer hold on, since the fastener grooves will be cut off and the corner will have to be glued.

Second

Practice creating a corner from the baseboard, as you would with a regular wooden element. Engage in "artistic cutting." This can be done using a grinder. Adjusting the angle is a painstaking task, but quite real.

If the interior angle is greater than 90 degrees

The trouble is the same: lack of fittings. In this situation, we get out of the situation in the same two ways. Just finishing the connector. It will close such a corner if the internal fasteners are broken.

We take into account that this part will have to be glued, since it will not hold naturally.

Well, the "artistic cut" also has not been canceled. Having suffered a lot with the grinder, trying to join two elements in such a corner, you can achieve the desired result.

How to fix a plastic plinth if you need to close the end of the podium

In such a situation, it is convenient to initially adjust the height of the podium to the height of the plinth. At least that the podium was not lower. But this is not always possible. And it's not always worth it. If this is an exit to the balcony, then a high threshold will disfigure the interior.

And with a plinth, you can close the threshold, which is lower than itself. After all, plastic is easily cut, and it is enough to accurately measure and carefully trim its lower part. Get something like this.

If you try, it looks very interesting.

Even more interesting than in the case when the threshold would be the same height as the plinth.

Such situations when installing plastic skirting boards are still quite rare. But, nevertheless, they take place. Now you are armed with the appropriate knowledge to deal with them.

If someone knows other ways to get out of such situations, share them in the comments 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

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

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.
