Proper floor preparation is a crucial part of our process. We begin by diamond grinding the surface to open the pores of the concrete and to remove any residual fluid contaminants. The concrete surface is then swept clean and vacuumed. All joints are caulked and a special primer is applied and allowed to cure for up to 24 hours. This primer starts the process of chemical and mechanical bonding that gives our flooring systems their unsurpassed toughness, chemical resistance, and durability. The epoxy or urethane coating is applied within a 24-hour period. The surface usually can receive light foot traffic 6 hours after the final coat, heavy items in 24 hours, and vehicles in 7 days.
