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.
