One of the main problems in construction is the protection of all parts of the constructed structure from direct contact with liquids. It is solved by different methods and using different materials. But are they all effective and convenient to use in any situation, the question is far from straightforward.
That's why experts always recommend to make a waterproofing complex, that is, combine several methods. Naturally, this will require more time, and the consumption of the corresponding products is significantly increased. The use of the means, called hydrophobizators, allows solving simultaneously different problems.
Such compositions sharply reduce the ability of all building materials to absorb liquids, not only on the surface, but also in the depth. By their efficiency and effectiveness they can be called analogs of several types of waterproofing - impregnating, roll, coating, etc., that is, they are products "for all occasions."
Features of water repellents
- Possibility to process any of materials( asphalt, bricks, slate, cement, gypsum, wood, etc.) used in repair or construction. At the same time, one must take into account that for each of them the "type" of products is selected.
- Many protective equipment allows the basis to "breathe", which excludes the appearance and development of fungus, mold( for example, in wood).They do not "seal" the pores of the materials( they do not form a film) like ordinary paints, and if they reduce such a parameter as vapor permeability, then not much( no more than 10-15%).And then, only some of them.
- Versatile application. It is possible not only to process the surfaces, but also to introduce as additives in the composition of various mixtures in the manufacture of "artificial" products( various types of concrete, blocks, tiles, etc.).This technology several times increases the operational life of the final product.
- In addition to the main purpose, perform a number of other useful functions, for example, increase the elasticity, frost resistance of materials.
Species
According to the chemical composition:
- silicone;
- on a water basis.
Application technology:
- Special paint and varnish.
- Stains.
- Means for impregnation.
In order to use the hydrophobizator to give the desired effect and not worsen the other characteristics of the base material, it is necessary to select the correct composition.
The products under the brand "SOFEXIL" ( several types) proved to be well established, the production of which is established in the Moscow region. It is possible to note a number of others - "Akvastat" , "Penta" .From the imported, "Kemasol" ( Slovenian-made) and German "Wakker" , "Aqnafin" , "Asolin" are in demand. And this is not a complete list of water repellents.
The cost of
It depends mainly on the chemical composition of the product and the specifics of its application, so the price spread is impressive. Some examples:
- "Tiprom"( Russia) - from 900 rubles for a capacity of 5 liters;
- German "AKEMI" for 5 liters - about 7,200 rubles;
- "Protect Gard"( France) is even more expensive - 2 180 rubles / liter.
