Abstract
A method of forming a very durable, waterproof, and unevenly textured coating film on the wall surfaces of a structure comprises an undercoating material consisting of a silicone-modified organic resin, an uneven textured intermediate coating material consisting of a short fiber-containing aqueous silicone emulsion which forms a rubbery elastomer by means of removal of the water, and a top coating material consisting of a silicone-type resin.
Claims8
A method of forming a waterproof, unevenly textured coating film on the wall surfaces of structures, which method comprises,
- (I) the formation of a cured film on the wall surface of a structure by application of an undercoating material consisting of a silicone-modified organic resin,
- (II) the subsequent application on the undercoating material of (I), in an uneven texture, of an intermediate coating material consisting of short fiber-containing aqueous silicone emulsion which will form a rubbery elastomer by means of the removal of the water fraction, followed by curing, and
- (III) the subsequent formation on the cured, intermediate coating material of a (II) a cured film by application of a top coating material consisting of a silicone-type resin.
