Abstract
The invention relates to a process for damp-proofing masonry, in particular for the surface sealing of interior walls, by waxy substances, the waxy substance penetrating the area to be damp-proofed by being heated during a reaction time and utilising capillary forces. In order to achieve non-destructive, ecologically harmless and durable masonry sealing which can be carried out with little expenditure, the waxy substance is brought into direct contact with the surface of a large area of the masonry to be sealed a heatable carrier, then being heated to temperatures above its melting point by heating the carrier, and thus penetrating the capillary system of the masonry, or that the waxy substance, distributed in a heatable carrier displaying a capillary system, be permanently applied to a large area of the section of masonry to be sealed, then being heated to temperatures above its melting point before or after application to the masonry, and thus spreading through the capillary system of the carrier.
