The way wet sandblasting works is simple: a probe (line) is used to draw in the sand (or any of the other materials discussed below being used as the abrasive substance) to the power washer extension wand where water will then be used to propel it toward the surface at high speeds.
In respect to this, does sandblasting use water?
Dry sandblasting uses air that is highly pressurized together with abrasives. Wet sandblasting uses water that is high-powered together with material that's abrasive or sand. The two methods do the same work of cleaning any surface.
In this regard, how do you sandblast with a pressure washer?
- Place the sand probe in a bucket of sandblast media, keeping the probe's air intake above the sand.
- Connect the sandblaster attachment to your pressure washer wand.
- Start the pressure washer, with the lance pointed away from your body and project.
You should use a tank with a minimum of 100 PSI for optimum efficiency with any abrasive sandblasting project. If you work with a lower PSI, you'll add a significant amount of time to your project. If you reduce your blasting pressure by half, your pressure cleaning project will take four times as long.
