Abstract
A process for covering a concrete surface with a cementitious coating. Portland cement is mixed with a polymer containing ethylene-vinyl acetate co-polymer and vinyl acetate monomer with water to form a cementitious mixture with a paint-like viscosity. This paint-like product is placed in a paint spray pressure pot and sprayed using a paint gun with a special spray tip to coat concrete and other substrate surfaces with a natural or integrally colored thin layered cement finish surface to be coated. The result is a surface that is free of stains, spots and discolorations, but with a concrete rather than a paint-like appearance.
Claims6
A process for covering a concrete surface with a cementitious coating comprising:
- mixing 100 parts by weight of Portland cement and from 15 to 30 parts by weight of a polymer containing ethylene-vinyl acetate co-polymer and vinyl acetate monomer with about 50 to 70 parts by weight of water to form a cementitious mixture with a paint-like viscosity;
- placing the cementitious mixture in a paint spray pressure pot;
- spraying the cementitious mixture on the concrete surface to be coated;
- and
- allowing the cementitious mixture to cure to provide a coated concrete surface.
A concrete coating comprising:
- 100 parts by weight of Portland cement;
- from 1 to 2 parts by weight of ethylene-vinyl acetate co-polymer;
- from 20 to 21 parts by weight of vinyl acetate monomer;
- and
- from 71 to 82 parts by weight of water.
