Decorative thin overlays for vertical application

摘要

Probably more vertical overlay cement finishes have been installed than any other type of decorative overlay. It has become a favorite way to finish millions of square feet of commercial building and warehouse walls. For the increasing number of concrete homes, which typically have polystyrene board insulation as the exterior wall surface, thin decorative overlay finishes make an ideal covering. Overlays can be used for both interior and exterior finishes and can be installed directly over concrete, drywall, or polystyrene insulation boards. Most products are rated for both vertical and horizontal surfaces and can be applied by trowel, hopper gun, or sprayer. They can be integrally colored or painted.
