NOTE: Abrasive media that has not been cleaned and screened could contain material that will clog the gun nozzle and should be avoided.
Moisture in compressed air will form into droplets as the air comes from the compressor pump. When humidity is high or when a compressor
is in continuous use for an extended period of time, moisture will collect in the tank. When using a sandblast gun, this water will be carried
from the tank through the hose and out of the gun as droplets mixed with the material being sprayed.
IMPORTANT: THIS CONDENSATION WILL CAKE THE SAND AND CLOG THE SANDBLASTING GUN. A CLOGGED GUN WILL NOT OPERATE.
A compressed air dryer and/or air line filter will help eliminate this moisture.

Suggestions
40 - 90
Move gun back and forth over the template in a
brushing manner. Blast at a 90
use glass beads for the abrasive. For drilling holes, use 30
sieve sand.
40 - 90
Use brushing strokes and watch the abrasion rate
carefully. Soft wood will wear faster than hardwood.
Smaller grit sizes gives smoother finish. Start with low
pressure and gradually build up pressure. Blast at a 45
angle.
40 - 70
Use brushing strokes and watch the abrasion rate
carefully. Use walnut shells for coarse finishing and glass
beads or fine sand for fine finishing. Blast at a 45
50 - 125
Be sure to mask any glass or painted surface that could
be accidentally damaged. Blast at a 80 - 90

Use larger grit sand on a hidden area. If the base
material is being damaged, use a smaller grit. Blast at a

Use a heavy grit sand with a sweeping overlapping
stroke. Blast at a 80 - 90
