One of the many sandblasting uses is for cleaning concrete surfaces. Concrete is a composite construction material composed primarily of aggregate, cement, and water. But this kind of surface posseses many qualities because not all the concrete is similar. There are many concrete formulations, which provide varied properties to this surface. Besides sandblasting can be used to clean or to texture the surface of hardened concrete.
I’ve just found an old pdf guide from the expert T.W. Hunt that I want to share with you due it is great and very useful if you want to sandblast concrete.
Enjoy it and improve your sandblasting!
