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

Galvanized plasterboard corner 25x25 mm - 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 it. However, prefabricated ones have problem areas - corners, which are most often subject to mechanical stress. This is where different types of existing corners come to the rescue.


Existing types of drywall corners

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

The following product options are most common:

Metal perforated corner

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

  • straight;
  • arched.

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

The straight perforated corner is used to machine the inside and outside of corners.

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


Metallic Perforated Drywall Corner Options

Actually, with their help, a high-quality connection with the processed corners occurs, and the top located at the inner corners - inside, and at the outer corners - outside, is a guide for the spatula. Excess air also comes out through the holes. Straight perforated corners are plastic, aluminum, galvanized. The latter is tougher than the 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. Among the advantages, we can note the low price and the absence of material corrosion. There is also a type of plastic corner, for example, AquaBead, which has special paper with glue applied in the inside. Putty for fixing is not required here, it is enough to moisten the glue surface with water and just glue the corner to the desired place.

Arched

Various finishing materials are used, such as plaster, wallpaper, panels and others. But in order to save the places of transitions between the planes, an arched corner is used, which has great capabilities. Arched corners are divided into the following types:

  • Installed under plaster, perforated. They have separate petals on one side of the corner, allowing sufficient stripe to be placed on any arched bend. There are plastic and from the profile;
  • Decorative, glued to plaster.

It looks like an arched corner for drywall

Before attaching the arched corner, it must be matched to the main finish or in contrast, so the design will look more original.

Products with mesh

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

Installation of corners on drywall using corners

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

Required material

  • the selected type of corner will need to be purchased with a certain margin;
  • through ;
  • it is best to buy Vetonit putty, which is of high quality.

Instruments

  • scissors for metal will help you cut the necessary parts correctly and quickly;
  • a brush that is required to apply the primer;
  • wide and narrow spatulas will be needed for;
  • a sanding block will remove all unevenness on the plane, while the angle will be perfectly even.

This is how the mounted corners look on drywall

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

Stages of work

  1. First, the plane must be thoroughly cleaned and primed. You need to proceed to the next stage only after it has completely dried.
  2. Measurements are taken, and the required length of the corners is cut. They are applied to drywall as a fitting.
  3. For further work, you will need a non-woven tape, a serpyanka mesh - for the inner corners, one of the types of perforated corners: plastic, adhesive, rounded or made of a metal profile or on a paper basis.
  4. Before making a choice. For the formation of the inner and outer corners, it is better to buy a dry gypsum mixture. It has a reasonable price, good quality and can reliably fix the elements to the structure.
  5. Prepare the putty in compliance with all stages: pour, pour, stir, allow to settle, knead again.
  6. When working with external corners, you need to remember that they are most often exposed to mechanical stress, it is better to fix metal samples, in some cases having a rounded shape.
  7. Check the flatness of the end.
  8. Putty is applied to the treated area with smooth movements. Without 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.
  9. Sometimes the corner is attached to the drywall with a stapler or glued with glue, and then covered with putty.
  10. One more layer of the mixture is applied to the installed element and now it is aligned with the common wall plane.

    Application of the second layer of putty

  11. After thorough drying, the slope corner is sanded.
  12. The installation of 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, remove the excess mixture. On a dry, sanded surface of the desired shape. You can buy it and just put it on a damp putty.
  13. check the fixing on the drywall of the corner, then hide the irregularities with the next layer.
  14. After thorough drying, the surface is finished with sandpaper or a polished block, while forming a perfect angle.
  15. To facilitate the leveling process, so-called beacons are used, attached to the surface with a plaster solution, here you can do without fastening parts.
  16. Separately, I would like to mention the semicircular plastic corner used in rooms with the maximum possible impact on the corners. It is made of flexible plastic and does not have a sharp corner, but a semicircular one. Its price is quite acceptable, and its strength is beyond doubt. It differs in some features at the installation stage, namely, by 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 parts of drywall are reinforced, and will also allow you to select and buy the necessary elements.


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

When the doors and windows are installed, you need to deal with the finishing of 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 properly cut and glue a corner made of plastic, cork or MDF? Below are detailed recommendations 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? Let's 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, 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 bulky things through the opening, which is fraught with damage to the corners, and you can just 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 view. In addition, as practice shows, most often the wallpaper begins to flake off precisely in these places. So it is best to protect the outer corner of the slope with a decorative element that will also transform the interior.

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

Plastic, wood or MDF - which ones to choose?

Making sure 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.

Use a fine-toothed hacksaw to trim the corner.

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.

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 figured out what such products are made of, what are their features and having decided on the choice, you should study how to install the corners on the slopes. Detailed instructions are given below.

The outer corners must be leveled and reinforced during the repair process, for which it is necessary to use a perforated corner of various sections. Today we will tell you about attaching a perforated painting corner to an external plaster or plasterboard corner, as well as clarify the stages of work and the materials necessary for this.

Materials and tools

The corner has a central stiffener and side strips with perforations, which help 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 gypsum plaster composition is used to fix it on plaster. External corners are not only vertical angles at the junction of two walls, but also cuts of plasterboard ceiling structures, as well as window and door slopes.

Instructions

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

When fixing at an angle from gypsum plasterboard, 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. Remains of the mixture that have broken through the perforations are removed. In this case, you can do without a level, because the gypsum boards are attached exactly and there is no point in doing the same job twice. With ideally even corners of the gypsum board structures, the corner is fixed with a stapler.

When attaching the corner to the plaster, most often the angle must be trimmed, therefore 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 3–4, and sometimes 5–7 mm above the surface of the side walls, then after fixing the element of the hole on the wall, it is necessary to close it with a plaster mixture using a spatula wide from 40 cm.

Putty and plaster for fixing the corner should be kneaded only in a plastic bucket, pouring water into it first and then adding the dry mixture and kneading it with a mixer. The consistency of the mixture is from "thick sour cream" for gypsum board and gypsum plasterboard 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 plastering works, fixing directly into the mortar body at an angle and plastic elements for curved corners.

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

A plastic skirting board 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 skirting board to such a place? If the radius of curvature is large and smooth, then there will be no problem. And if the radius is small and steep enough?

Try this. Use a metal saw to make cuts on the back of the skirting board so that the plastic is not damaged outside. Be careful! The cut skirting board 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 skirting board on a rounded wall.

Most likely, you will have to do so. But it will be necessary to fix the plastic skirting board in the place of the rounded wall more often than on level places. Just a few centimeters later, new fasteners!

How to attach a plastic skirting board if the outside angle is more than 90 degrees

Such interior details are also not uncommon now.

An example of installing a plinth on an outer corner of more than 90 degrees.

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

Typically, fittings are represented by four parts; outside right angle, inside right angle, end cap and connector. With an external angle greater than 90 degrees, there are two options for operation.

The first

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

The plastic corner itself will no longer hold, since the grooves for the fasteners will be cut off and you will have to glue the corner.

Second

Practice creating a corner from the baseboard as you would with a regular piece of wood. Engage in an "artistic cut". This can be done using a grinder. Adjusting a corner is a painstaking task, but quite real.

If the inside angle is more 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. We are just finalizing the connector. It will close such a corner if you break off the internal fasteners.

We take into account that you have to glue this part, since it will not stick naturally.

Well, no one canceled the "artistic cut" either. Having suffered a lot with a grinder, trying to dock two elements in such a corner, you can achieve the desired result.

How to attach a plastic skirting board 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 skirting board. 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 a threshold that is lower than itself. After all, it is easy to cut plastic, and it is enough to accurately measure and carefully trim its lower part. It will turn out 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.

Similar situations when installing plastic skirting boards are still quite rare. But, nevertheless, they do. You are now armed with the appropriate knowledge to master them.

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

Finishing corners in an apartment should be used in cases when small children or animals are kept in the family. Since plaster finishing mixtures are not very durable, they are destroyed by light exposure to them.

Outer corners are especially prone to destruction. Papered corners are often dented, and painted corners are chipped.

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

Immediately, we note that the process of finishing the corners in an apartment is a difficult and crucial stage. It is much easier to get a smooth surface than to level the corners. Next, we will consider ways to protect the corners of the walls in the apartment and house from damage

When do you need to trim corners?

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

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

Which material is best for corner protection

In any room, the 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, expanded polystyrene, wooden corners, special galvanized metal profiles, decorative stone are most often used.
Plastic corners have a wide range of colors. They have increased softness, varying degrees of roughness.

To the question: "How to decorate 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 are understood to be the use of drywall, and the use of metal, wood, expanded polystyrene corners, PVC corners as devices.

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

The corners of the walls are protected by installing special devices. As a protection for the corners of the walls, corners of different materials are most often used.

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 assembly glue for plastic products.

Plastic corners are produced in lengths of 2.5 m. The width of the corners is different, from narrow to wide.

To correctly select the corners in width, you should measure the curvature of the corner.

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

Narrow corners are applied at almost even corners

How to properly attach plastic corners to wall corners?

Option 1

    1. 1. With the help of the building angle, you need to measure the deviations of the angle.
      2. Knead the mortar of the required consistency from the dry putty mixture.
      3. Apply the mortar with an ordinary spatula, level it with a corner, giving the corner a rectangular appearance.
      4. After the corner is completely dry, attach the 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. 1.Plastic corners are installed on a previously prepared surface. If necessary, remove the old wallpaper with a knife on the drywall, clean the surface of the old paint.
      2. On the inner surface of the corner, apply glue with a step of 30 ... 50 mm. The glue is applied in dotted lines.
      3. When the glue reaches the desired viscosity (indicated in the instructions for the glue), attach a 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 protecting wall corners 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 expanded polystyrene corners.


Expanded polystyrene corners
Expanded polystyrene is a non-combustible material.

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

The surface of the polystyrene corners is paintable. Corner profiles are created by pressing and produced in various shapes.

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

Decorative corners made of expanded polystyrene allow not only to protect corners, but also to decorate corners.

Mounting is possible both with special glue and with ordinary acrylic sealant.


Wood corners
The main advantages of wooden corners are:

  • attractive appearance;
  • environmental friendliness;
  • the ability to create carving or decoration.

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

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


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

Let's note right away! It is better to use a decorative stone. It is lighter than natural. And the presence of a smooth surface greatly facilitates maintenance.

The stone is fixed with a special solution or tile glue.

Step 1

The surface should be prepared for laying decorative stone,
clean from dirt, dust, old coating 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
The glue is diluted according to the attached instructions in quantities that you can use during the work. The properties of the glue are maintained for 2 hours.

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

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

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

Step 6
After placing the stone in three rows, stop the work. The glue hardens completely after two hours. This will allow the next 3 rows to continue.

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

Drywall when finishing corners
The use of gypsum plasterboard sheets allows you to align any, most curved corners.
There are two ways to mount drywall sheets: frameless, frame.


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

  • surface preparation is in progress;
  • 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 out with a knife and cuts of the mating corners of drywall are made with a plane;
  • prepared blanks of plasterboard sheets are again applied to the corner and adjusted;
  • polyurethane foam is applied to the sheets;
  • both blanks are applied to the wall and pressed;
  • sheets are removed, leaving traces of polyurethane foam on the wall;
  • polyurethane foam is reapplied to the sheets;
  • the foam should be allowed to dry a little and the sheets should be put in place;
  • it will remain to correct the angle using a wooden batten or a 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 value of the angle deviation;
  • 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 putty, polished;
  • the corner is protected by a perforated mesh.
