Abstract
A high gloss coating on a mineral substrate, such as a roof tile or floor tile, can be achieved by a method comprising: PA0 i) forming said substrate from an uncured mineral composition, preferably a green concrete, clay or fiber cement; PA0 ii) forming a continuous layer of film-forming polymeric binder over a surface of said substrate formed in i) by: PA1 a) applying to said surface a first coating composition comprising film-forming polymeric binder, and PA1 b) destabilizing said first coating composition prior to application of, upon contact of, or subsequent to application of said first coating composition on said surface; PA0 iii) applying to the coated surface formed in ii) a second coating composition comprising a film forming polymeric binder; and PA0 iv) drying and curing said coated substrate formed in iii), for example in an oven or autoclave.
