Abstract
A method of fabricating stone-simulated articles including facings for substrates, involving roller-flattening mixtures of preferably polyester resins, curing agent, polyester-dispersed pigments, fumed silica (and other) filler and aluminum trihydrate filler into flat stone-pattern-simulating surfaces or slabs, maintaining the same sufficiently cool (as by refrigeration) to prevent curing until it is desired to use the same, and then applying to, and rolling over a substrate to be covered or faced, or otherwise forming the same into the desired article, and permitting to cure under the action of said curing agent, with the resulting product containing the stone-simulated pattern throughout.
