POLYSTONES uses an interlocking and overlapping panel system that may be installed quickly and easily to achieve the beauty of natural stone, rock, slate or brick on your building without the need of a stonemason, and at a fraction of the cost. This unique wall covering panel system is mortar free and very user friendly. The panels are installed easily with standard woodworking tools (cut with a standard skill saw, trim with sharp knife/blade and attach with polyurethane adhesives and metal screws). These impact resistant panel designs provide authentic stone, rock and brick colors while remaining resistant to harsh weather, solvents, pests, mould and mildew. POLYSTONES panels attach directly to wood, concrete, brick, steel, stucco or any flat substrate for easy installation.
