How does a wet sandblast attachment compare to a commercial sandblaster?

The Effectiveness of a Pressure Washer Sandblaster

Adding a sandblasting attachment to a pressure washer can be very effective. However, how well wet sandblasting works also depends on the application that you are using it for. For instance, if you have a pressure washer capable of pumping out 4 GPM at 3,000 PSI, your unit will use 250 pounds of abrasive if used continuously for an hour. It has about half the effectiveness of a commercial sandblaster. However, sandblasting with a pressure washer is ideal in small building jobs where you already have a unit available. Environmental jobs may require you to wet sandblast. Building restoration projects in historical structures may also use wet sandblasting in lieu of chemical cleaning.
