    • A high gloss coating on a mineral substrate, such as a roof tile or floor tile, can be achieved by a method comprising:

      i) forming said substrate from an uncured mineral composition, preferably a green concrete, clay or fiber cement;
      ii) forming a continuous layer of film-forming polymeric binder over a surface of said substrate formed in i) by:

      a) applying to said surface a first coating composition comprising film-forming polymeric binder, and
      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;

      iii) applying to the coated surface formed in ii) a second coating composition comprising a film forming polymeric binder;
      and
      iv) drying and curing said coated substrate formed in iii), for example in an oven or autoclave.
