Installation
It is recommended that sandblasting equipment be
used with commonly available sandblast cabinets. How-
ever, a temporary sandblasting booth can also be used.
MAKING A TEMPORARY SANDBLAST BOOTH
To make a temporary sandblast booth, refer to Figure 7
and follow the outlined procedures below.
Material needed:
1 roll of 3" plastic tape
1 large corrugated box
4 square feet of plexiglass
1/4 yard of old cloth
1. Cut a rectangular hole out of one side on the box to
serve as a window opening. Leave a least a two inch
border around the cutoff for strength.
2. Cut the plexiglass two inches wider than the cutoff
dimensions. This will be the top of the booth.
3. Cut two five inch round holes in one or two of the
other sides of the box for arm holes.
4. Cut two pieces of cloth approximately eight inches
wide to act as a curtain for the arm holes. Tape the
top of the cloth pieces to the inside of the box so that
the cloth hangs over each hole.
5. Cut a 1-
1
/
2
inch hole in the corner of the flaps on the
open end of the box for the air and material hoses.
6. (OPTIONAL) Cut a small hole in the unopened end
of the box for inserting a hole from a shop vacuum.
This will aid in clearing dust and collecting sand for
reuse.
To use the sandblasting booth, put the booth on a work
bench with an overhead light. Put the object to be
sandblasted and the sandblast gun into the box. Tape
the open end shut.
Operation
1. Always wear a safety shield or safety glasses,
gloves and a respirator when sandblasting.
2. Locate the compressor as far away as possible
from the sandblasting area to minimize the dust in
the compressor intake.
3. The higher the air pressure (maximum 125 PSI),
and the closer to the work , the quicker the job will
be done.
4. Use a large grit abrasive to remove material and
use a small grit to smooth surfaces.
5. Always trial test the sandblaster to make sure the
job is done without damage by testing on a hidden
surface.
6. Always filter (screen) the abrasive material to re-
move any caked material and prevent clogging.
7. Use a compressor that can supply enough air (See
Specifications). A compressor too small will cause
air pressure to drop and the sandblaster will not
operate satisfactorily.
8. Do not try to spray heavy liquids.
9. When spraying devices such as carburetors, stuff
rags or paper into all openings to prevent internal
damage.
10. Use the lowest effective pressure on soft surfaces
to prevent pitting the surface.
11. Whenever the nozzle is removed and replaced, use
a brush to clean the threads and replace the o-ring.
12. Soap and water can be used for cleaning purposes
for automobiles, lawn chairs, etc.

PLEXIGLASS
MOISTURE IN COMPRESSED AIR
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 con-
tinuous use for an extended period of time, mois-
ture 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 (MP2121)
