Wall saltpeter is called salt which gathers for surfaces of brick walls over time. The reasons of its emergence can be different: atmospheric precipitation, low-quality brick, mainly low temperature on the street, some other temperature and moist conditions.
Instruction
1. Completely to remove wall saltpetres from brick, it is not enough to stock up with large amount of water and brushes. By the way, it cannot lead to anything good. Metal brushes destroy brick even stronger. Water, having got inside, will simply extend even more salts on surface of bricks. The fact is that those soluble salts that accumulate on bricks, become insoluble connections over time. These connections should be deleted only with special structures. In this fight use hydrophobisators. These are special cleaners. They give to different construction materials additional property of pushing away of water. So-called hydrofobization - magnificent method. It is also the main way of prevention of emergence of wall saltpetres. After processing the possibility of washing away of salt is excluded from bricks. The main thing that the hydrofobization will not pass more water in brick. Liquid will flow down balls on the wall. The brick will not become wet at all.
2. It is very important not to change exterior of laying, not to spoil surface, esthetic look. For this purpose use special snowplows when cleaning facade of salts. Such cleaners both salt, and limy deposits, and atmospheric pollutions are removed too. On intensity of action on bricks there are different cleaners. For example, "Tipry OF" apply on external part of wall by means of brush, the roller. In half an hour it is possible to wash away excess cleaner plain water. Other means, such as "NEOMID 550 Antisol", "ArmMiks" and others use according to the enclosed instructions.
3. Also prevention of salt raids on walls is possible. It is very simple. Begins with technology of laying and material selection of walls. It is better to refuse laying of laying of brick absolutely in the winter. But if it does not work well, then avoid the moments when the rain and snow fly to the unprotected laying. For cement slurry use frost-resistant additives. Further, that wall saltpetres were not, walls are isolated by roof and drains from atmospheric moisture and waterproofing from soil moisture.
