Suggestions
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.
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.
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
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
80 - 90
o
angle.
Use a heavy grit sand with a sweeping overlapping
stroke. Blast at a 80 - 90
Use brushing strokes and watch the abrasion rate
carefully. Soft wood will wear faster than hard wood.
Smaller grit sizes five a smoother finish. Start with low
pressure and gradually build up pressure. Blast at a
45 - 60
o
angle.
Remove flaking paint first with wire brush, then
sandblast with a heavy grit abrasive. Multiple layer of
old paint should be scraped first. Prime immediately
following sandblasting to prevent corrosion. Blast at a
45 - 60
angle.
