Wet Sandblasting

Definition - What does Wet Sandblasting mean?

Wet sandblasting is a technique to remove paint and rust from steel, metal or other hard surfaces. In this procedure, abrasive material like sand is mixed with water and sprayed. Wet sandblasting is the most common sandblasting technique and is more efficient than dry sandblasting. It can be used to achieve the desired metal finish required prior to recoating.

Wet sandblasting eliminates the dust and airborne contaminants therefore it is a safer option for clean environment.

Corrosionpedia explains Wet Sandblasting

Wet sandblasting is a technique for the removal of old paint and debris from concrete, stone and metal surfaces and plastered fa├žades using wet abrasive media such as sand. The mixed fraction is selected as per the strength of substratum, paint thickness, chemical composition and number of layers .

Large scale applications of wet sandblasting are evident in bridge work, road surfaces and curb repainting. Wet sandblasting equipment is commonly used to remove paint or other substances before making repairs or recoating surfaces of this large structure.

Since wet sandblasting uses moisture as part of the sanding process, this may expose uncoated metals to immediate corrosion. In this case, the metal may be protected using a primer or sealer.
