RsSandstone™ is a product with special characteristics that allow it to be easily applied over knockdown textures, smoothing and leveling the wall or ceiling surface. The material’s translucent white coloration and anti-collapse formulation make it eminently suited for this purpose. The crushable sand-like aggregate is actually tiny hollow stones that allow the product to be utilized in a number of decorative ways. Similar to the other products in the Rs Series line, RsSandstone can be mixed with RsActivator to easily create unique, textured effects.
