Abstract

A process for cleaning and regenerating the surface of asbestos-cement concrete blocks (10) within building structures is novel in that the soiled or weathered face (14) of the asbestos-cement concrete blocks (10) are first coated with a reacting resin paste to form a coating (18) which is allowed to remain in place while the viscosity increases. Before the coating (18) hardens, part of the surface (18, 20) is skimmed off taking with it embedded loose dirt, dust and fibre particles (16, 12) from the concrete surface. The remaining (18) coating is then allowed to harden. <IMAGE>
