Sandblasting is similar to pressure washing, in that an extreme buildup of pressure behind the sand or water helps propel the sand or water through a hose at a surface. While the water in a pressure washer cleanses, the sand in a sandblaster grinds away the surface. The next time you are looking at a stone and brick building that looks like it could use a good cleaning or facelift (inside or out!), you might want to consider professional sandblasting to solve any of the following issues. It will yield amazing results.
Spray paint on a brick or stone surface is incredibly difficult to remove. In most cases, a pressure washer cannot erase the paint completely. A sandblaster, however, can use the abrasive qualities of forced sand to grind away the graffiti and spray paint, leaving a very smooth and spotless surface. If you so choose, you can even use a two-pronged approach to remove the graffiti. First blast away the fresher spray paint with the pressure washer, and then use the sandblaster to remove the older graffiti and traces of paint that the pressure washer could not remove.
Polishing Marble Inlays
If you are trying to restore an old building or old home that contains some marble elements, there are only so many cleaners and products you can use to help you restore and polish the marble. A light application of sandblasting can remove dirt from the surface of the marble, and another pass or two with the wand can help you smooth and polish the marble. If you want to remove marble inlays instead of polishing them, then a harder grit of sand combined with a higher level of pressure may loosen the inlays enough to remove them with a light tap and/or a screwdriver.
Scraping Away Years of Paint and Wallpaper
Just as a sandblaster can remove the graffiti from the exterior of the building, it can also remove the numerous layers of paint and wallpaper stuck on the walls inside. At the very least, a sandblaster can help remove some of the worst, thickest and most difficult spots of wallpaper and paint. If you do the sandblasting yourself instead of hiring a professional, make sure that you stop blasting the minute you cannot see anything but plaster or drywall board. If you attempt to blast beyond that, you may create large holes in the wall that will be very expensive to repair.
