MicroLock Technology top coat provides several additional benefits including:  Anti-microbial additives, which prevent the ability for bacteria or fungus to grow or spread. Adding a top coat “seals” the surface of the polyvinyl material, ensuring that dirt, debris, bacteria, fungus and other microbes do not penetrate the surface, provides an additional stain and UV resistance, as well as ensures the material becomes non-porous for ease of cleaning.
