Sand is the most commonly used material. Other materials that can be used are steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell.
When painting, one doesn't want to trap dust, dirt, or bubbles in a previous layer of paint, or other imperfections under the new layer. By launching small bits of abrasive at the surface at a high, medium or light speed, all imperfections are knocked loose and can then be easily washed off, creating an incredibly smooth surface upon which to lay the new layer of paint. Sandblasting may also be used for such projects as cleaning the hulls of ships or large structures such as the Golden Gate Bridge.
Sandblasting Items
- • Iron steel ~ Aluminum ~ Stainless steel ~ Copper ~ Brass
- • Wood
Metal
Sandblasting is performed on virtually ANY metal object, from patio furniture to car parts, and creates a smooth surface due to the abrasive qualities of the sand. After sandblasting, the metal object has been thoroughly cleaned to remove all traces of dirt and grease and is prepared for powder coating.

After sandblasting, the metal object must be thoroughly cleaned to remove all traces of dirt and grease as well as residual traces of sand that will interfere with the powder.
Wood
Sandblasting can resurface or shape wood in minutes. It's efficient, but is typically done only by professionals. It requires a steady hand with deliberate, dedicated motion. Sign makers and woodworkers use sandblasters to weather wood for special projects, blasting away soft grain to make the wood appear as if it has been floating around in the ocean. Others use sandblasting to strip wood of paint or old finishes.
Sandblasting is a great preparation method for Powder Coat. When powder coating, it is very important for the item you are coating to be completely clean of oils, dirt, paint, rust, corrosion, and damaged plating (zinc, nickel, chrome, etc.).
