How to Sandblast to Remove Paint

Save

Sandblasting is a very quick and efficient way to remove paint from a hard surface, such as a driveway or vehicle. It is very important, however, that you know how to safely operate and use the sandblaster. Always consult your sandblaster manual to determine what type of material to load the sandblaster with, as different surfaces require different types of sand grit. In addition, the manual will tell you what air valve setting to use with which surface. Different sandblasters have different settings, so this will vary according to what model you have.

Things You'll Need

  • Breathing mask
  • Safety goggles
  • Work gloves
  • Media (sand for the sandblaster)
  • Detach the air supply hose from sandblaster, then fill the sandblaster with the necessary media (grade and type of sand). Reattach the supply hose and turn on the air compressor so that the hose will fill with air.

  • Twist on the air supply valve counterclockwise until the needle on the gauge approaches the PSI setting you wish to use, then twist the valve clockwise and press the knob on the compressor. You will hear it lock into place.

  • Open up the air valve on the sandblaster, which will allow the air from the supply hose to enter the sandblaster itself.

  • Aim the nozzle of the sandblaster at the surface you wish to remove paint from, and press the valve on the nozzle, then open up the sand valve on the blaster. The sand will be propelled out with the force of the compressed air, and will begin stripping away the paint.

  • Spray the sand in a left to right motion. Gradually move the stream closer to the surface until you can see the paint being stripped away. To turn off the sand blaster, let go of the nozzle valve and close the sand valve.

  • Disconnect the air supply hose from the sandblaster when you are done using it.

Tips & Warnings

  • Always wear the proper protective gear when operating a sandblaster.
