Odourless transpiring water repellent based on siloxane resins in solvent solution suitable for impregnating absorbent building materials with medium to high porosity. It does not form superficial skin and does not alter the support appearance. It is permeable to water vapour and resists longer than normal silicon materials to ageing; it prevents the formation of salt efflorescence and saltpetre. Rain Murosan is ready-to-use and is applied by means of brush, roller or spraying device on the support to be treated.
