Ironing technology of the blind area

The blind area along the perimeter of the building performs a protective function and prevents damage to the base. In addition, it retains heat, enhancing the building's performance. It is therefore important to keep the protective circuit in good condition. To do this, use the procedure for ironing the blind area.

Concrete has good strength, but this is sometimes not enough, and then it becomes necessary to carry out additional work. Ironing is the last stage of arranging a concrete blind area, which implies processing the coating with cement mortar. The procedure is designed to strengthen the surface and give it additional properties.

With the help of iron, it is possible to improve such characteristics as:

• strength;

• hardness;

• resistance to water.

Additionally, it is possible to prevent concrete crumbling and flaking, which is typical for a material that is exposed to regular mechanical and climatic influences. After ironing, the water easily leaves the walls of the house and the blind area, which prevents the negative effect of the liquid on concrete. If you ignore the procedure, the life of the concrete will decrease, the structure will quickly crack.

The most common component for ironing is considered to be pure cement grade 400 or 500. Sometimes sand is added to the composition to reduce consumption. At the same time, it is important that the sandy material is clean, there should be no clay impurities in it.

And also to create the necessary composition for ironing, waste from the following industries is used:

• mining;

• electric;

• chemical.

There are several methods of ironing the blind area. Basic ways:

• dry;

• wet;

• method using polymers.

It is worth considering in more detail each of these options and analyzing how to properly iron it.

One of the easiest ways. It is used when no more than 2-3 hours have passed after cementing the blind area. To achieve the desired result, it is necessary that the blind area remains slightly damp.

Let's mark the key stages of ironing with our own hands.

1. First of all, a uniform "spraying" of cement is performed over the surface of the blind area. The maximum layer thickness should not exceed 2 mm. For better spreading of the material, it is better to use a sieve, which must be tapped periodically.

2. Next, using a hand float, level the created surface.

3. The third stage involves waiting. It is necessary to give the composition time for the cement to become more durable.

As a result of the dry method of ironing the blind area around the house, a strong material is formed. You can walk on the structure a day after the work.

In this case, to achieve a reliable result, liquid cement is used, due to which the name of the method arose.

Recommendations for work performance:

• kneading the solution is in a one-to-one ratio; sand and cement are used to create a solution;

• to improve the properties of the mixture, lime dough is added to it in the amount of 10% of the total mass of cement in the solution;

• the prepared solution is best applied to the surface of the blind area by scattering the mixture, followed by leveling.

It is important to note that wet ironing can be started only 2 weeks after the blind area has hardened. During this time, the blind area will be able to fully stabilize, and the structure will not crack in the process.

It is carried out using polymer tiles and polyurethane. The sequence of actions is the same as in the case of dry ironing. Therefore, there are no difficulties in completing the task.

Before laying tiles or applying polyurethane, the surface of the blind area is impregnated with special compounds. The most common brands are:

• "Lithurin";

• Pentra;

• "Spectrin" (Spektrin).

Search for impregnations from these manufacturers in the appropriate store.

For better ironing in all methods, it is worth using a metal grater. With its help, it will be possible not only to align the composition, but also to achieve strong adhesion of materials. The advantage of using a grater is the possibility of ironing at any time of the year.
