Abstract
Novel thin flexible decorative colored cementitious veneers of about 5 to 60 mils in thickness, useful in wall coverings, floor coverings and on ceilings; and methods of producing said thin decorative cementitious veneers wherein printing, embossing and casting are performed simultaneously. The basic method comprises the steps of placing a wet cloth on a mold engraved with a design followed by placing a plastic cement mix on said wet cloth to simultaneously form a casting and a temporary cloth mold which is the exact copy of the original mold, immediately removing the plastic cement casting together with the temporary cloth mold from the original engraved mold before it sets, thereby making the original mold immediately available for the next casting, removing the temporary cloth mold from said plastic cement casting before it sets, and air curing said casting while being stored.
