A mold process for producing a finished solid surfaced countertop in which a mold of the product to be produced is placed in a substantially horizontal manner. A series of barriers are constructed atop a flat polished surface of the mold and creates a negative shape of the countertop product to be produced. A release wax surface is applied over the exposed edges of the mold and is followed by the spraying a predetermined layer of a high-quality resin surface coating. The coating is allowed to gel to a point at which a plasticized substrate material is poured into the mold and over the resin surface coating. A catalyst is added to the substrate material prior to pouring and elevates the temperature of the substrate and the surface coating during the hardening and curing process. The surface coating bonds to the substrate and cures without the development of pinholes or other imperfections in the surface coating. Subsequent layers of substrate material may be poured to reach any desired thickness and then one or more backing portions are attached to the countertop to permit the countertop to be attached to a cabinet. The finished countertop is allowed to harden and cure within the mold for a given period of time and is then removed from the mold to cure for an additional period of time.

A mold process for producing a finished solid surface countertop, said mold process comprising the steps of: placing in a level position a mold; creating atop said mold an enclosure having a negative shape of a countertop part to be produced, said enclosure including a top surface and elevated side surfaces; said step of creating said negative shape of said mold further comprising the step of constructing a plurality of barriers onto a flat polished surface of said mold; spraying a continuous layer of a high quality resin coating material evenly across said top and side surfaces of said negative shape enclosure; allowing said resin coating material to set and to gel for a predetermined period of time to form a gelled resin coating; pouring a layer of a substrate material in a liquid state into said mold and over said gelled resin coating to form a substrate layer, said substrate layer including a catalyst which increases a temperature of said substrate layer and facilitates hardening; building a dam atop a gelled surface of said substrate layer for receiving a subsequent layer of substrate material atop said gelled surface of said substrate layer to produce a built-up edge; cooling and hardening said layers of substrate material causing said continuous layer of a high quality resin coating material to cure and harden and to bond to said substrate layer; and removing the finished countertop from within the mold.
