What is a plastic corner

This plastic product- Part decorative design window and other slopes. The corner is intended for closing the corner joints formed when using various materials.

Types of corners

According to the design of the product are divided:

• Rigid construction;
• flexible (soft) folding profile.

Rigid construction

It is a classic rectangular profile. Both shelves are connected into one whole. The product is produced by the method of longitudinal bending of a strip of PVC (polyvinyl chloride) when exposed to high temperature.

The front surface of the profile can be made matte or glossy. In addition, in order to give decorative properties, the product is available in various color scheme, - monochrome or with the application of a special film.

To protect the front surface, some manufacturers apply a protective film that is removed during installation.

Do-it-yourself installation

Angle setting is carried out on different kinds surfaces, in addition, having a variety of sizes. From here follows the first stage of work - preparatory.

Surface and corner preparation

Most simple work are performed on flat planes, formed, for example, plastic panels. The essence of the operations is wiping the surface from dust and, if required, degreasing.

A concrete, brick or plaster wall will most likely require additional leveling, by means of plaster followed by puttying. Next, it is necessary to impregnate the freshly dried coating for two or three passes with an acrylic primer.

The use of impregnation is advisable to use on GKL sheets (gypsum plasterboard). This is done in order to create a dense, non-absorbent base on which the adhesive will be applied.

Preparatory operations with corners are performed after completion of work with the surface. Defined:

• the dimensions of the overlap of the corner joints with the addition of 5-10 mm on each side, - for the adhesive composition;
• the length of the corners with the required configuration, for example, for slopes, the upper parts are cut at an angle of 45 ° - this operation is more convenient to perform with a hacksaw and a miter box.

Necessary tools and materials

You will need:

1. Stationery knife with replaceable 18 mm blades. It is convenient for them to cut small parts of a plastic corner or, for example, adhesive tape.
2. Miter box and hacksaw for metal. This set is convenient to use when you need to make a clear cut under the size of 45° or 90°.
3. Scissors for metal or tin. They are used for cutting plastic to the required size.
4. Measuring tool. This includes:
   • construction square with an angle of 90 °;
   • ruler;
   • tape measure at least 3 meters long;
   • plumb.
5. adhesive composition. Views are determined by the slope material, for example:
   • on a plastered or plasterboard surface, it is advisable to use glue from the "liquid nails" series or alcohol-based compounds - such products are used for installation ceiling plinths or styrofoam tiles;
   • for fixing on a plastic surface, it is more convenient to use glue with fast time setting, - "second" or, for example, Cosmofen CA-500.
6. Masking (paper) adhesive tape, - is used to fix the decorative element to the surface during the gluing process. This technique allows you to free up time for other operations, and not stand with outstretched arms and press the product against the wall.

Installation instructions

Stages of work:

1. Surface preparation.
2. Execution in the size and the necessary configuration of decorative elements.
3. Setting corners - the process consists in applying adhesive composition on the surface and gluing in the required place. Fixation, when using "second" glue, is carried out within a few seconds. The use of other compounds will require additional fastening with masking tape, after 4-24 hours, it is removed.

Tip 1. When buying a flexible corner, pay attention to its shape taking - if the product does not hold the given configuration, then it is better to refrain from buying.

Tip 2. In the case of small volumes of work (up to 10 meters) on plastic surfaces, it is more expedient to use a "second" glue-gel - it does not spread, otherwise it is better to use more professional tool, – Cosmofen CA-12.

Tip 3. It is necessary to buy decorative elements after when it is clear angular size slopes. For a clear 90 °, a rigid profile is suitable, with deviations in a larger direction, it is more convenient to use a flexible folding product.

Tip 4. When applying compositions from the "liquid nails" series, it is necessary to pay attention to the initial setting force - it should not be less than 40-50 kg / m².

Together with abundance building materials, the market is constantly updated with new elements that greatly simplify the implementation repair work and at the same time give an improved appearance housing, both inside and out. We will talk about one such element today - these are corners for slopes. It helps to emphasize the slope line and give it a complete look. Since there are a lot of options for plastic corners, you need to figure out which elements to use for a particular case.

Then install the putty corner and press it into the solution and use the level to check the verticality. The squeezed out mixture is removed with a spatula, and work then stops for a while until the solution sets. Then the plastering process takes place, and the corner must be completely hidden under the right amount mixtures. During this installation, the corner bar allows you to display the maximum even corners slopes.
