Wet blasting is a cleaning process that uses liquid to enhance a surface’s finish levels. Though it was created to mitigate the ban on silica in sand blasting, it has remained a popular finishing method due to its many advantages over the previously used method of sand blasting. However, with wet blasting systems, the abrasive and water mix is more gentle on the part surface because the water acts as a cushion.

In a pressure blast machine, the abrasive media is contained in a pressure vessel under pressure (at 40 to 100 psi) for use in the process. Examples of this abrasive media include steel shot or grit. Once the valve is open to start blasting, the media moves from the pressure pot through the grit valve and then through the hose to start blasting under pressure using the gun or nozzle. The media has two-to-three-times times the velocity on impact and would be close to three-times faster with stripping applications. Normal blasting pressure ranges from 35 to 45 psi. (more…)
