Patent ID: 7842739

Claim:
A method for applying a compact hardened coating to a surface which comprises the steps of: (a) separately conveying to a mixer: (i) a first component which consists essentially of: a 60-70% mixture of bitumen and water in a quantity of 50 to 100 partial mass %, 0 to 50 partial mass % synthetic latex or natural latex, polyvinyl acetate emulsion, or acrylate emulsion, paraffin emulsion or wax emulsion and 0 to 10 partial mass % viscosity control agent, thixotropic additives and adhesion improving additives; and (ii) a second component which consists essentially of: 20 to 50 partial mass % filling material selected from the group consisting of rock meal, talc, cement, lime powder, gypsum, fly ash cement and scoria derived from iron or steel production, 40 to 80 partial mass % softening, non-volatile oil and 0 to 10% by weight viscosity control agent, dispersing aids and wetting agents for oily phases, and wherein the first component and the second component are present in a ratio of 100:10 up to 50 mass %; (b) mixing the first and second components in the mixer to form a mixture of the first and second components; and (c) applying the mixture of the first and second components onto a surface as a seamless liquid foil, where the first and second components undergo a hardening reaction on the surface to increase viscosity of the seamless liquid foil, and to produce from the seamless liquid foil, a compact, hardened coating on the surface, wherein the compact hardened coating is applied to the surface at a temperature from +1° C., upward, including during late fall or winter.
