ABSTRACT:
A process is disclosed for covering a substrate with a cementitious simulated ceramic surface having a mottled, speckled appearance. Cement and sand are mixed with an aqueous solution of an adhesive resin to create a viscous liquid mortar. The viscous liquid mortar is applied onto randomly spaced portions of the cementitious substrate to create a noncontiguous thickened cementitious coating having a high viscosity to prevent spreading of the liquid mortar over the cementitious substrate. The noncontiguous thickened cementitious coating is troweled to form a plurality of interconnecting and non-interconnecting flattened and level plateaus partially covering the cementitious substrate to reveal a simulated mottled, speckled ceramic covering.
