Today it is the most popular decorative element for the final finishing of PVC windows.

How to properly install plastic corners with your own hands? And what are the nuances when installing plastic corners?

How to attach plastic corners?

First, we note that before directly installing the plastic corners on the windows, it is necessary to cover the corners with wallpaper, paint, etc. That is, you can start attaching them only after all finishing work has been completed.

For mounting a plastic corner you will need the following tools:

assembly adhesive (liquid nails)
masking tape (scotch tape), and in a room with high humidity– silicone sealant
metal scissors or hacksaw
pencil
directly PVC corners

Finishing windows with plastic corners consists of several stages. Let's look at each of them:

Preparing the surface for gluing PVC corners

1. Remove all protruding parts: curtain nails, wallpaper, even any protrusions on the wall. To do this, knock down part of the plaster.

We cut off the wallpaper near the slope - to make it easier to tear it off if you plan a renovation

2. Remove the wallpaper from a corner of the wall. Otherwise, you will stick the plastic corner not on the wall, but on the wallpaper, which is wrong.

Cut the wallpaper to such a width that there is no gap between it and the plastic corner.

3. Degrease with a weak solvent, or so-called. white spirit that part window slope, on which the plastic corner will be attached.

Preparing a plastic corner

1. Place the plastic corner against the wall and mark it with a pencil (on top and between the side slopes).

First point: The side corners are measured after gluing the top corner. And the bottom one - after installing the side ones. This makes it less likely that there will be gaps between their edges.

Sometimes the outer sides of the corners are cut off after installation

2. Carefully make cuts along the resulting marks using metal scissors. Trim the inside edges of the corners at a 90 degree angle. And the external ones are 45 degrees.

Second point: If you have any excess left on the plastic corner, cut it off with a hacksaw.

Third point: the corners must be strictly straight, and the width of both sides must be the same.

Installation of plastic corners on slopes

After installation, the corners are fixed with tape for a day

1. Apply a thin dotted layer of glue to inner side plastic corner, closer to the center. The glue is applied at intervals of approximately 10 to 15 mm.

3. Press the corner onto the surface along its entire length.

4. Secure the plastic corner for a day in two or three places with masking tape/adhesive tape.

5. Once the glue is dry, carefully remove the masking tape.

So, by observing all the subtleties when installing plastic corners on windows, you can correctly attach PVC corners with your own hands without any effort.

Such decorative element, like a plastic corner, has, among other things, important practical significance. Its main task is to protect corners as well as materials exterior finishing from mechanical damage. Such wall materials include wallpaper, window trims and window openings, arched structures (arches), and sometimes baseboards. Today we will take a closer look at how to glue a plastic corner, what glue to use, what types of this there are structural element, and which size is better to choose.

The main purpose

As noted just above, main reason attaching a protective PVC corner for wallpaper, arches and tiles to the corners of walls is not only a decorative function, but also the protection it gives for certain construction or finishing materials in the interior of apartments and houses. With this design, you can protect various vulnerable areas from damage that can be caused by impacts from pieces of furniture of various sizes, careless handling of household appliances, and sometimes overly playful children and pets.

Attention! If you decide to stick on a decorative plastic corner, then be sure that this mounting element will not only provide safety for wallpaper, PVC panels and window slopes, but will also make the interior of the room more “complete” and attractive. So, let's look at the gluing process in more detail.

Types of plastic corner

It should be noted that in terms of its purpose, as well as in appearance, this fastener may be different. The following types can be distinguished: external, internal, perforated, colored, decorated “like wood”. In addition, some of its types can be used for work on the ceiling.

Advice! If you are not satisfied with the color of the PVC corner and want to paint it, then you should use the same rules and instructions as when painting other PVC surfaces.

As for which size is better to choose: look at the situation, guided by both aesthetic and practical considerations.

How to stick it correctly

Before fixing the corner, it is necessary to carry out certain preparatory work. To start, plastic material needs to be cut and adjusted. This can be done with a sharp knife or durable metal cutting scissors, since their household counterparts can be easily damaged during the cutting process. Please note that working with a knife is fraught with danger, therefore, it must be done with extreme caution, in compliance with all necessary safety measures.

In addition, pruning work can be performed using a grinder. Please note that in this case it is recommended to use a metal carving disc. Take into account the fact that it depends on how smoothly and efficiently the trimming was performed. overall quality work.

Do not forget! There is no need to use silicone to hide the imperfections of an uneven trim. The fact is that after some time, areas covered with silicone may begin to become covered with dust, spoiling the overall appearance corner, as well as the place that was closed to them. If the work is performed not by you, but by hired specialists, then we also recommend carefully monitoring how they perform their work.

Think for yourself: it’s better to have a small but even gap along the entire length of the corner than a dirty one that is not always neatly covered with silicone or acrylic sealant. The point is also that this fastening element can have different colors and be colored.

Here are the most common color options:

Black.
Grey.
Transparent.
White.

What to glue and what glue to use

So, what glue is best for gluing plastic corners? One of the most optimal options are so-called "liquid Nails". With their help, you can firmly and reliably glue this decorative element not only in all rooms, but also in the bathroom or kitchen, which, as you know, are places with high humidity, requiring all fastenings to be made with increased resistance to such difficult conditions. By the way, choose liquid nails that will become transparent after installation. In addition, it is possible to use acrylic sealant of the appropriate color.

In addition to purchasing glue, you will need to buy a special gun with which you can apply liquid nails to the work surface. When applying glue, you must be careful: apply the glue in a thin wavy line, closer to the middle wrong side corner. This way, you will significantly reduce the likelihood that glue residue, when pressed, will fall on the decorative front side. In those cases when glue residues do get on the front side or on the wallpaper, you must first wait for them to dry completely, and only then carefully remove them using a sharp knife, scalpel or blade.

Now a few words about how to properly fix the corner while the glue dries. If when working with smooth and flat surfaces(for example, window slopes) you will have fewer problems, but for example, when installing on arches that have a curved silhouette, certain questions may arise. In order to secure the corner, in such cases it is advisable to use various types of tape (choose in each specific situation, based on your conditions). The most common types of mounting tape are:

Painting.
Packaging.

Conclusion

In our case, of course, the most the right decision will use masking tape. With its help you will need to fix the corner. The adhesive tape must be removed the next day, provided that the glue has completely dried. By the way, many people wonder: how to bend a corner. In fact, in arched structures this is not required, since it is soft enough and will itself take on the contours of the arch (if they are not too sharp, of course).

In the same cases when the angle work surface is quite sharp (for example, 45 degrees), or the radius of the arch is small, you can cut the plastic corner into several parts and secure each of them separately in the manner described above, carefully joining them.

The abundance of modern materials appearing on the construction market simplifies repair and finishing work. Relatively new, but very convenient and already in demand parts include colored plastic corners for slopes. Their appearance made it possible to solve the age-old problem - the difficulty of perfectly smooth removal and insecurity external corner slope, but, in addition, they allow you to emphasize its line, hide the imperfections of the plaster and give design window opening finished look.

What are plastic corners?

In order to obtain a plastic corner, a PVC sheet is taken at production. Due to the fact that polyvinyl chloride is a thermoplastic polymer, after strong heating it is easily bent at the required angle. The cooled plank remains strong, hard and reliable, and thanks to this technology it has no cracks and has a smooth, neat surface.

The material itself, polyvinyl chloride, is a colorless polymer, but to improve decorative properties manufacturers began to produce it in the most diverse color solutions. In addition to traditional white ones, we offer colored plastic corners for slopes: pink, blue, yellow, light green, brown and others. Due to this, they can be harmoniously introduced into any interior. Such diversity color range made it possible to significantly expand the scope of application of these elements; now they are used on: slopes of window openings and doors; external corners; arched openings; corners covered with wallpaper (to protect easily abraded material); joints at exterior decoration buildings using siding.

Features and types of corners

Exist different types plastic corners for slopes. First of all, they are divided into:

internal;
external. This type, in turn, is divided into two subtypes according to the angle rotation: 90 degrees and 105 degrees.

Also, when choosing corners for slopes of plastic windows, pay attention to their sizes. They can be from 10 mm to 50 mm. In most cases, L-shaped products are used in shape; there are also T-shaped ones, but they are used much less frequently. To avoid making a mistake when choosing corners for installation on slopes, use several rules:

if the corner is constantly subject to wear, then you should choose an L-shaped corner measuring over 20 mm and up to 50 mm;
if the corner is not subject to severe wear, then it is rational to install plastic corners on the slopes small sizes: 10mm*10mm or 15mm*15mm. They look aesthetically pleasing and neat, almost invisible, and the angle line is clear;
neat and smooth transition from wall panel a T-shaped profile installed at the joint will provide the slope, here the dimensions can be: 12 mm * 10 mm, 18 mm * 10 mm, 20 mm * 10 mm and 22 mm * 10 mm;
in the case of an arched window, provision is made for installing plastic corners of different genders on the slopes, i.e. with specially made uneven sides. They bend perfectly and form a correct and presentable frame.

About the advantages of PVC for corners

Plastic, metal and wooden crafts, but the first type is more in demand. When choosing a suitable option for yourself, the advantages of plastic corners for slopes can be noted that this material:

durable and reliable;
durable;
hygienic (easy to clean, does not absorb dust and dirt);
is not afraid of moisture and is resistant to corrosion;
costs less than metal or wood;
does not require additional finishing or painting;
Available in different colors, so it’s easy to choose a tone to suit any interior.

Separately, we should highlight the ease of its installation.

How to install plastic corners

Before gluing plastic corners to the slopes, you should remove the wallpaper adjacent to the corner to a distance equal to the part of the corner extending onto the wall. The freed surface must be degreased (a weak solvent solution will do). Then, inside the corner (closer to the bend), you need to apply glue with a thin dotted line (the distance between the dotted lines is approximately 10 mm) and press it to the prepared surface along its entire length. It is recommended to start work from the upper slope. Next, you need to glue masking tape or tape to the corner, this will ensure reliable fixation until the glue dries completely. After 2-3 days, the tape is carefully removed.

It’s not difficult to choose what to glue the plastic corners to on the slopes - so-called “liquid nails” will do.

Step-by-step photo instructions “How to glue PVC corners to window slopes” will help home handyman make the finishing touch to the repair of window or balcony openings and walls. The procedure for decorating slopes, in addition to the aesthetic component, is also necessary to protect the corners from abrasion upon contact in everyday life.

The edges of wallpaper are particularly susceptible to various damages, therefore, after completing the main repairs, you must immediately begin installing the decorative corners.

Currently, the leadership in accessibility and ease of installation belongs to polyvinyl chloride (plastic) corners. Available for your choice a large number of shades and sizes.

“” suggests familiarizing yourself with the technology of installing a PVC corner using the example of a window slope. So, before installing the corners on the slopes, calculate the perimeter of the window and, when purchasing a PVC corner, try to buy blanks longer than either side. Thus, you will avoid installing unnecessary joints on a straight section, and the price of this material allows you not to save on trimmings.

In order to glue the corners to the slopes, in addition to the plastic corners themselves, we will need:

glue (for example, “Moment”),
sharp knife,
molar tape.

1. According to the measurements, cut off the corner of the required length with a small margin of 2-3 mm. The margin is necessary for a more accurate fit and to eliminate errors when measuring. Next, we try on and trim until it matches completely.

2. Wipe the corner with a dry cloth and inner surface PVC corner.

3. Apply glue to the inside in intermittent strips. There is no need to spread it over the surface of the corner, because... During installation, the glue will take its place on its own.

4. Carefully lean the workpiece against the slope and lightly press it exactly into the corner. If, during the pressing process, glue residues appear on the outside, immediately wipe them off with a clean rag;

5. For secure fixation, starting from the middle and moving towards the edges, glue pieces of masking tape across the corner. We advise you not to skimp on tape and stick it often and in long pieces.

6. Next important stage– this is the installation of the horizontal part and adjustment of the angle. To avoid complications when joining at 45 degrees, we recommend connecting at right angles. If you suddenly get a not quite even fit at the corners, eliminate this defect by covering the gap with white silicone.

7. We install the last slope in the same way. We leave our backbreaking work alone for a couple of hours. Keep windows closed both during and after work, without drafts.

8. When the time is up, remove and wipe the corners soap solution from glue residues. All, PVC installation– the corner on the window opening is completed.

After plastic windows installed, it is necessary to make Finishing work, which involve the installation of external and internal slopes. There are several ways to install them: you can attach them to a pre-installed installed frame or glue the slopes to the windows using various adhesives.

Types of materials

Work can be performed using the following materials:

Mounting method on polyurethane foam

You can glue the slopes to the windows using polyurethane foam. This is a universal material with a high degree of adhesion. How to glue plasterboard slopes in this way is shown below.

Why should you choose plastic products?

Plastic is the most common and versatile material.

Plastic slopes are most often installed

This is due to its performance characteristics and ease of installation. The advantages of plastic slopes include:

Easy to care for the surface - just wipe the plastic with a cloth and soapy water;
High-quality plastic does not fade when exposed to sunlight;
Plastic looks best combined with the profile surface of plastic windows;
The service life of these products is calculated in decades;
For plastic slopes, when insulating them, you can use mineral wool. In this case, heat loss is reduced through window design and the effect of window fogging is eliminated;
The moisture resistance of the plastic is obvious, so it does not collapse under the influence of condensation;
Simple installation - the parts just need to be treated with adhesive and fixed to the surface of the base.

Installation

Glue plastic slopes can be done in the traditional way - by polyurethane foam. This installation has some differences from that used for plasterboard slopes.

What is liquid plastic

Liquid plastic has recently appeared on the construction market. It has found application in many areas, including the installation of plastic slopes.

Liquid plastic is used for gluing plastic slopes

Liquid plastic is a type modern sealant, which can be used as glue when attaching plastic slopes. The content of liquid PVC in its base gives this material many positive qualities.

Mode of application

Using this glue, you can guarantee strong adhesion between the material and the surface.

Using liquid plastic when processing joints and seams, you can be sure that it will never acquire yellow, as happens with silicone analogues. This ensures a neat appearance of the window opening.

During temperature changes indoors plastic panels, secured with silicone, may lose the tightness of the connection. And the panels, placed on glue in the form of liquid plastic, will stay in place for many years.

When working with this material, it is important to consider that it hardens in one minute. This is the interval during which it is necessary to apply it and distribute it over the surface. You need to work quickly and efficiently the first time.

It is also worth considering that liquid plastic is quite toxic due to the chemical reaction, therefore, when working with it, you must use a respirator and ensure a flow of fresh air into the room.

It should be noted that after the glue based on liquid PVC dries, it will become absolutely harmless to environment and people.

Positive qualities of liquid plastic

The appearance of this modern material did not go unnoticed by the specialists involved in the installation metal-plastic windows. For them, the question of how to glue plastic slopes has disappeared forever. Liquid plastic is characterized by the following positive qualities:
