• Also, if the vertical angle is not perpendicular to the axis of the earth, then not a large deviation can be completely aligned using just the corner.

Types of corners and materials for making a corner

Plastic wall corners are selected according to the type of angle.

There are two options here:

Inside corner Inner corner	Internal corners generally do not fall into the risk zone, since they are difficult to access. Although it is not particularly susceptible to mechanical stress, its evenness is sometimes extremely important.
Outer corner Outside corner	But external corners are always a headache, as they are easy to damage. They do not have high strength, wallpaper can be torn off, peeling paint.

Corners are installed at the end, after all installation and repair work has been completed. Corners are glued to the wall with mounting glue for plastic. If you are doing this type of work for the first time, then you need to use corners of medium width, and the height of the plastic corners is standard 2.5 m.

Installation of corners

Glue is the most necessary thing to install the corners. Since the reliability of fastening depends on it. On the market today, a lot of all kinds of glue are sold, each different in composition, properties.

How to choose the best glue? If you choose it incorrectly, then you can spoil the external aesthetic appearance.

Let's look at what species exist and what they are suitable for:

Polyurethane adhesive Fixing a plastic corner to polyurethane	It has a number of positive aspects - leaves no residue, elastic, has high strength. It is most suitable for gluing a corner with plastic panels. But there are drawbacks, it has a sharp smell and a long gluing, about two days. You need to apply such glue over the entire surface of the corner, do not glue immediately. It takes about 30 minutes to allow the glue to harden slightly.
Liquid Nails Fixing a plastic corner to liquid nails	The most popular glue. Gained its fame due to its high strength. It is also called mounting glue. It contains sodium carbonate, which allows you to fill the voids between the corner and the wall. It is great for gluing plastic corners with any type of wallpaper. If you use white corners during installation, it is better to buy transparent liquid nails, with other shades of wallpaper you can use any glue composition. Note that liquid nails do not spoil the plastic corners and wallpaper. Apply glue to the plastic corner with a snake.
Sealant Fasten the PVC corner to the sealant	This is a complex glue. The choice must be approached with all responsibility. A sealant is needed to bond plastic to tile. Note that not every sealant can be used for bonding plastic. Experts say that it is better to use acrylic sealant. It is durable for bonding plastic, has no color and odor. And has increased moisture resistance.

Attention: When deciding how to stick a plastic corner to a wall, it’s worth looking at what you will attach the corner to. Then there will not be unforeseen circumstances and the installation will be successful. Glue is applied to the corner pointwise.

Preparatory work

When we work with right angles, then we should not have any special problems. The plastic corner is easily cut using a construction knife or a hacksaw.

We cut a plastic corner

But with arched work, not everything is so simple. Here we need to bend a straight plastic corner. How to do it?

Bend the plastic corner with a hairdryer

• From the above, we can recall that at high temperatures a plastic corner easily changes shape. To do this, we need a building hair dryer, we heat the corner, give the desired shape, fix. We continue work after the plastic cools down.
• Often corners are in the dust in the store, so before work, you need to clean them, degrease, wipe dry. Not a drop of moisture should remain on the plastic, if they do get caught, the glue will not fix well, and may fall off over time.

Large bend angle

Note: For the arch, a corner with notches is selected. If you took a straight line, then you need to make incisions along the contour with a hacksaw.

Technology for bonding plastic corners

Each type of material has its own system for gluing plastic corners. We will analyze all cases in detail.

So that you already know exactly what you need to do:

• To glue a plastic corner to the wallpaper, you first need to pick it up. It is better to choose a corner to match the wallpaper, it looks aesthetically beautiful. Measure the height that is needed.
• After you need to cut it off. This is where the biggest problem arises for non-professionals. The plastic corner is cut at an angle of 45 degrees. Specialists do it by eye. But since you are not a professional in this matter, then you need to take a miter box and scissors for metal.

We cut a PVC corner using a miter box

Attention: The hacksaw must be taken with metal or with a small tooth. Otherwise, the material will bite and you get an uneven cut.

• After cutting the desired length, prepare the plastic corner itself. Wipe off dust; check if there is water; if present, wipe dry.
• Now you need to prepare the wallpaper, remove the wallpaper at the junction of the corners. In this case, you need to use liquid nails.However, if you have light wallpapers, then choose a light glue, and if it is a dark shade, then any color of glue will suit you.
• Apply glue to the plastic and to the wallpaper evenly, but do not overdo it, since removing this glue from the wallpaper is unrealistic.

Glue the plastic corner to the walls in the same way as in the previous case:

• Clean the wall, prepare a corner, wipe off dirt, check for moisture. We use another glue, required for painted walls, acrylic sealant. Apply gently to the inside of the corner and attach to the wall. Exactly the same process is performed when gluing a plastic corner to the slopes.
• The most difficult type of work is attaching a plastic corner to an arched opening. Choose the type of glue based on what type of material is laid on the wall. Next, bend the plastic corner, as we described above.
• Now we turn to the hardest - cutting plastic. On the side that goes to the inner opening, we cut butt. And from the outside we leave a reserve. Then there will be an opportunity to trim. The method of gluing itself depends on the materials.

Now you have the initial knowledge of installing plastic corners. You can safely proceed to practice. As you can see, the installation process is not so complicated, but it is invaluable. And note that their cost is not high. I can even buy them with a limited budget for repairs.

Corners perfectly preserve the primacy of the room. Since they will protect the most vulnerable places in the interior. And the room will please you more than one year.

Plastic corners to protect the corners of the walls will help you maintain the geometry of the angle even under mechanical stress. And the instruction will help to do the job quickly and efficiently.
