Hydrophobization of facades - the best preparations and application procedure

Hydrophobization of facades includes a set of measures to ensure reliable protection of building materials from moisture. The need for this process is due to the porous structure of brick, concrete, foam block, gas block, wood. Any material used in the construction of walls and floors has its own service life. Hydrophobization can significantly extend it, improving characteristics such as strength and moisture resistance.

Hydrophobization of facades - the best preparations and application procedure

Hydrophobization of facades

There are two types of hydrophobization: volumetric and surface.

The first is performed during the production of building material, but it does not always provide the necessary degree of its protection. Surface hydrophobization is the process of applying a special solution to the facade of a building and other materials.

Which facade needs hydrophobization

The facade is in contact with the environment every second, which has a detrimental effect on it. Modern developments in the field of building materials protection allow minimizing the influence of moisture and ultraviolet radiation. When building new houses, this opportunity is taken into account and realized.

But in addition to new buildings, there is a huge number of long-operated buildings.

A facade that requires hydrophobization

Hydrophobization is a relatively new concept that not every owner of a private house knows about. Therefore, it is important to familiarize yourself with the list of signs, the presence of which will help to understand whether the building needs additional protection.

Sign # 1. The presence of efflorescence

Due to the porous structure, water molecules and various salts that make up its composition circulate inside any building material.

This is an inevitable process due to the nature of the substances. At positive ambient temperatures, water molecules rush to the surface of the facade and evaporate (evaporation process). The salts associated with them remain on the material in the form of a whitish precipitate. These are efflorescence.

The presence of efflorescence negatively affects the durability of the house

They are formed year-round, since the saline solutions do not freeze.

But in the cold season, the intensity of the appearance of efflorescence is noticeably reduced. In winter, the evaporation process is slowed down, salts crystallize inside the material, destroying its structure. As a result, the design life of the facade is reduced.

Sign # 2. The presence of wet and dirt spots

Foam concrete and aerated concrete are classified as highly hygroscopic materials.

Water droplets and damp spots can often be seen on the surface of these building stones. Dirt and dust circulating in the air settle on the damp surface of the façade, significantly reducing its aesthetic appeal. This applies not only to foam and aerated concrete, but also to brick, concrete, natural or artificial stone.

The climate of the region is of great importance. If the air humidity is high, the process of destruction of materials is more intense.

Therefore, for areas with a maritime climate, the construction of structures from porous and hygroscopic materials is not recommended.

Sign 3. The presence of fungus and mold

The presence of pathogenic microflora indicates an increased level of moisture in the building material with all the ensuing consequences: destruction and premature aging.

Sign 4. Water drops protruding on the surface of the facade

Considering the above, it can be concluded that it is reasonable to take care of the facade protection in advance and prevent the appearance of signs of erosion and other negative processes.

For this purpose, a complex of products on a chemical and organic basis has been developed. And the process for their application was called "hydrophobization". There is no doubt about its necessity.

How to hydrophobize the facade

Facade protection - this is a complex of actions, the last of which is hydrophobization. First, the surface of building materials is cleaned of dust and dirt, disinfected, and only after that a protective coating is applied.

This is a difficult and slow process. But its result is confidence in the strength and durability of the foundation, walls and floors.

If a chemical-based product is selected, personal protective equipment must be used: gauze mask or respirator, glasses, long-sleeved clothing, boots.

Personal protective equipment

A large area will need to be treated, so the use of paint brushes is inappropriate. To apply formulations, you will need either a long-handled roller or spray machines.

The best choice is equipment for disinfection or painting surfaces. You can use the STORM disinfectant applicator, WIWA airless spray, TAIVER painting units.

Façade protection companies offer a wide range of services, including:

  • dirt removal with a high pressure washer with and without the use of chemicals;
  • acid cleaning of facades and interfloor ceilings (including decorative concrete);
  • removal of efflorescence;
  • washing of facades from any building material;
  • applying a water repellent.

The full range of works is necessary in rare cases.

For a specific building, choose the list of services that are needed. If you decide to do the hydrophobization of the facade yourself, you should be ready for a large amount of work and stock up on the equipment necessary for their implementation.On average, to protect a building with a short service life, you will need:

  • washing the facade (if necessary);
  • removing local efflorescence (if necessary);
  • removing fungus and mold (if necessary);
  • application of a hydrophobic composition.

The best means for hydrophobization of the facade

The choice of a composition for protecting the facade is similar to the choice of any other means:

  • are guided by the number of positive reviews;
  • take into account the time criterion (the reliability of the product must be proven by practice);
  • give preference to highly specialized manufacturers who are constantly improving their products.

In order to facilitate the task of choosing a water repellent, a list of the most effective and popular is presented.
