For the past 15 years, father and son duo Wayne and Morgan Sellon have focused primarily on the residential home market, installing decorative wall surfaces, and interior and exterior finishes over almost any substrate to simulate rock masonry and wood beams. They have used many, if not all, wall products available and even developed their own vertical overlay cement mixes and texture mats, which produce the look that they want. After texturing, Sellon handcarves his wall surface to complete the rock patterns and wood shapes. The finished work is colored and sealed.

For their demo, the Sellons created the front wall of a store, featuring rockwork, stucco, and concrete wood beams. He worked on a wood stud wall covered with drywall. His first step involved attaching expanded polystyrene foam (EPS) blocks to the wall where he intended wood beam finishes to be placed. Then he applied a base coat of polymer cement to the EPS and the drywall. The first areas of concern for him were the rock finishes. He plastered a second application of material, textured the surface with his texture mats, and then waited until the overlay was stiff enough to handcarve rock shapes. In the same manner, he finished the wood beams and did the fill-in stucco work. Coloring with water-based stains followed with an application of sealer.
