FIELD: construction.

SUBSTANCE: invention relates to cleaning of surfaces made from natural and artificial stones, ceramic materials and may be used for cleaning buildings faces and interiors from atmospheric contamination and for maintenance activities. Method of buildings faces and interiors cleaning includes cleaning with water, drying and applying hydrophobisated compositions in two layers. As soon as the first layer is applied, it is exposed before the second layer application during the time needed for complete hydrophobisated composition absorption. Polysiloxane resin emulsion Tego Phobe 6600 is dissolved in water at ratio 1:4-5 and used as hydrophobisated composition for the first layer. As hydrophobisated composition in the second layer, a composition is used, that contains styrene-acryl dispersion, silicon resin or silicon resins mixture, pigments, disperser, thickener, emulsifier, foam killer, preserving agent, coalescent and water at the stated ratio of components.

EFFECT: cleaning of surfaces and protection from recontamination.
