Sandblasting is a highly effective method of cleaning solid indoor and outdoor surfaces. The process involves the use of compressed air to forcibly project sand at a target in order to remove dirt, residue and other finishes almost instantaneously. A sandblaster unit is capable of restoring nearly any surface to its original, bare condition using minimal effort. Play sand, or sand commonly used for playgrounds, is a suitable choice of media for certain projects that require sandblasting.
Things You'll Need
- Protective eyewear
- Hooded painter's suit
- Play sand
- Plastic sheeting
Put on protective eyewear and a hooded painter's suit. Wear a respirator before sandblasting to avoid inhaling the sand and dust particles.
Shut off the air valves on the sandblaster and fill the tank with play sand. Start the compressor and leave it to pressurize between 40 and 100 PSI (pounds per square inch).
Clear the workspace of anything that could be hit by stray sand. Play sand granules are larger than the more commonly used silica sand, which is much finer. Cover any exposed indoor surfaces surrounding the target with plastic sheeting or tarp if you want to keep them clean; otherwise, an outdoor setting is ideal.
Set the sandblasting unit to a low pressure setting and stand 8 to 16 inches from your target. Point the nozzle at the surface and squeeze the trigger to dispense the play sand, blasting the area top to bottom for even coverage.
Gradually increase the pressure setting if necessary until you reach the desired results. Play sand is rather coarse in comparison to other forms of sandblasting media and will work quickly to restore a surface. Use sweeping motions for large segments of the target, and short bursts of sand for trouble areas and small details.
