WallSpray

Wall Spray is a cement-based overlay designed for both interior and exterior vertical surfaces. It offers a wide variety of finishes from a simple knock-down to a sophisticated faux Venetian Plaster. Wall Spray may be applied by compressed air spray equipment and/or by trowel. Restoration, repair, resurfacing, architectural accenting, and surface protection of existing cladding are all realized through Wall Spray. Typical
areas include retention walls, entry/accent walls, columns, gable ends, fireplace accents, and any other vertical surfaces or walls. Wall Spray is formulated to provide excellent bonding to new as well as existing concrete, concrete block, ICF, polystyrene foam, drywall, plaster, plywood, and even painted surfaces.
