Where does the surface cleaning begins? From testing a small surface of the surface. Since it should be identified from a wide variety of salts the desired. This is done so that the type of cleaner that can best cope with the alla data on the facade of the building.
I want to know how much the labeling machine is now costing? You can visit this site and find out the exact price there.
Further, the selected cleaner is directly processing the facade completely. Each type has its own volume. For example, the Tiprom of OF Cleaner, which is a red fluid in color. 1 liter allows you to process 3-4 m2 from the entire area of the facade. And one liter of concentrated Tiprom Plus Cleaner is enough for 15-30 m2.
After processing heights, it is recommended to carry out hydrophobization.
Protecting the masonry of bricks from the effects of water in the warm seasons of the year, various variations of domestic and imported siliconic hydrophilizers are used. After processing, the surface type does not change if such substances as “Tiprom K” were used. However, there are deep penetration hydrophobisators, and they have a number of advantages. For example, “Tiprom M” is used at temperatures reaching – 5 degrees. There are more frost -resistant hydrophilizers: “Tiprom U” provides the ability to process the facade at -10 0C. And the concentrate of the Hydrophizer “Crystallisone” can be used in the processing of wet materials. It can be brick, concrete, ceramic tiles, plaster. As well as cement-fibrous slabs, shells, slate, marble. One liter of such a solution can be used for 155 m2.
You should know that silicate bricks requires a hydrophobizer with great penetrating ability, such as, for example, Protect Guard FT.
There are many diverse types of hydrophilizers on the market, both Russian and imported. However, it should be borne in mind that the small penetrating ability of some solutions will not give a long enough result.
