Hydropobizer "Title" from Sazi
Some time after the completion of the construction of the house on the outer facing of the artificial stone, whitening sweeps often appear, significantly deteriorating its appearance. These are the so-called sprinkle raid. It is formed for various reasons. Most often, due to the presence of salts in the solution to which the stone is placed. Almost all major producers of decorative stone are produced for installation of products, specially designed formulations, when using the sediments, it should not occur. However, often builders, guided by the desire to save, apply the usual concrete solution when working with artificial stone. What is it fraught with? In cement and so many salts, and some additives, for example, anthorts, increase their quantity. Moisture (from the atmosphere, with a braid rain, from soil- in case of disruption of the waterproofing of the foundation and bellied parts of the building, from the ultra-insulation in the roof waterproofing), falling on the solution, flushes soluble salts and alkali from it and takes them to the surface. After the interaction from the carbon dioxide contained in the air and the evaporation of moisture is transferred to an insoluble (or hard-soluble) crystalline shape and form a white flare. By Ktaku, the result provides use when laying an artificial stone (in winter) frost-resistant adhesive compositions, which contain a large number of salts. Therefore, manufacturers strongly recommend working with this material in the warm season.
Another possible reason for the appearance of heights is an application in the manufacture of a stone of various additives and additives.
Get rid of salt spoken on the stone with water and a rigid brush, it is not always possible. The fight against heavers consists of two stages: cleaning with the use of washes and the protection of walls from the re-occurrence of blesses by means of hydrophobizers.
Wasters and solvents to remove sections are a mixture of organic acids and (or) inorganic origin. Today there are a lot of money on the market as imported production (Alkutex Combi WR and Alkutex AC Klinkerreiniger-Paste Remmers, Germany; Extraclean from Index, Italy; keranet from Mapei, Austria) and domestic: the cleaner "of" from "from" Sasi "," Penta-860 "series," Penta-870 "," Penta-880 "from" Penta "," wall cleaner "from" Berath "IDR. The cost of these compositions is from 120 to 400 rubles / l. Consumption on average is 0.3-0.5 liters / m2.
However, it is not worth a hurry to rejoice at the sight of various tanks exposed in the construction stores with the inscription "Removes the Solutions". The fact is that the composition of the height is always multicomponent. They are carbonate-calcium, carbonate-sodium and sulphate sodium. Juniversal washing for all types of heights, alas, does not exist. There are two ways: call a specialist who will take a sample with salt drills and will recommend the necessary tool, or act on its own "method of trial and errors" - did not fit one drug, try another.
Since the composition of the funds are often harmful to the health of the substance, it is necessary to observe precautions: work in protective glasses, rubber gloves, prevent hopping on the skin. The cleansing drug is applied to the surface of the wall with a brush, brush or roller, are kept for 10-30min, and then the residues of the solution are washed with water.
After the cleaning of the walls performed, they need to be protected from moisture, for which hydropobizers are used. By the way, experts recommend that processing must be carried out once a year. Hydropobicators are silicone substances (siloxanes) that do not create a solid protective film, but possessing water-repellent properties. The composition is applied with a brush or a sprayer in two layers. Hydropobicators are liquid and pasty. Among the hydrophobizers presented in the market, FUNCOSILSNL and FUNCOSILOW from Remmers, Asolin-WS from Schmburg (Germany), Polyfluid from Alpa (France), "Polyfluid" from "Sasi" IDR are available. The average cost of compositions - 250-380 rubles / l. The consumption of substances is 0.25-0.5 liters / m2.
The moisture equipment is also almost all known Russian manufacturers of artificial stone: for example, the Aquafobizer "Villa da Vinci" from Villa da Vinchi, the silicone hydrophobizer Chelsea from the Chelsea Group, the Arstone hydrophobizer from the company "Perfect stone" IDR.
Carefully conducted two-stage processing of the heap gives excellent results and prevents the appearance of saline flops in the future.
