Abstract
A method for producing a replicated stone surface comprising the steps of preparing a polymer mortar, coating a substrate with the polymer mortar, leveling the polymer mortar to a substantially even thickness, creating a textured surface on the polymer mortar, applying a hydrophobic release agent to the surface of polymer mortar, displacing portions of the polymer mortar by pressing a patterned tool on the surface of the polymer mortar to form the plurality of simulated stones with raised peripheral edges and intervening simulated grout lines, allowing the polymer mortar to cure, applying a pigment to the surface of the plurality of simulated stones and simulated intervening grout lines, buffing the surface of the plurality of simulated stones and simulated intervening grout lines to impregnate the pores thereof with the pigment, abrading the surface of the plurality of simulated stones to create a weathered appearance and sealing the surface of the plurality of simulated stones and simulated intervening grout lines with a sealer to protect the replicated stone surface.
