Beschreibung
Zusammenfassung:	FIELD: building materials industry. SUBSTANCE: described is use of organosilicon perfluorocarboxylic acid amide as hydro- and olephobic agent for protection of building materials from adverse effect of environment. Building materials are not subjected to destruction for prolonged period of time due to using salt solution and repeated freezing and defrosting. Vapor tightness of limestone and plaster samples remain substantially unchanged after treatment procedure. EFFECT: improved hydrophobic effect of 197% of contact wetting angle of 135-140. 2 cl, 2 ex, 1 tbl
