What Is Sandblasting?
· The sand is then "blasted" across the surface, and because of its abrasive properties, the sand is able to create a smoother surface. Concrete, for example, is often sandblasted. After the concrete has been poured and allowed to dry, it's treated with sandblasting. The process removes some of the excess material on the concrete, which in turn makes it smoother.
