Wet Sandblasting - A Top Feature of Gas Pressure Washers

Pressure washing machines have always been known for their high cleaning power—whether electric or gas pressure washers. Some of the latest features have made these machines more flexible and even more powerful than before. Wet sandblasting is one such feature.

What Is Sandblasting?
Sandblasting is the technique of using fine grains of sand for cleaning rust, paint, and other dirt from hard surfaces, especially metal and glass. Normally, a machine such as a pressure washer propels the sand onto the metal or glass surfaces. A common application of the technique is to smoothen and flatten a metal surface before repainting.

The Process and Machines
Modern gas pressure washers are available with wet sandblasting technology. The difference between wet sandblasting and other methods like air sandblasting is that the former is much safer. The main problem with sandblasting is the likely health hazards it can inflict on the workers.

Inhalation of dust and silica particles is a prime danger associated with sandblasting. Consequently, the process is systematically controlled to limit the workers’ intake of dust. The whole cleaning process is a three- or four-step affair, which often requires a skillful cleaning worker.

Benefits of Wet Sandblasting
Wet sandblaster pressure washers greatly limit the dust of sand propelled into the environment from the hose of the machine, thereby limiting the quantity of dust inhaled by the operators. In these gas pressure washers, sand is propelled to the surface along with the water output of the machines.
