The application of such design on glass and metal, which is now
being used for wall surfaces, opens a new field for the decorator
equipped with an LA Abrasive Gun.

Stencils for production purposes may be rubber or metal. For a
single stenciling operation, stencil paper fastened with rubber
cement will prove adequate. Paint and art supply stores carry
necessary materials.

INSTRUCTIONS:

1. Abrasive guns can direct a limited amount of abrasive or a
strong blast when treating larger surfaces.
a. Trigger controls volume of air.
b. The nozzle can be adjusted and locked for material

control.

2. To operate: Fill polyethylene bottle 3/4 full of selected
abrasive. Use Aluminum Oxide, Pumice, Starch or other
abrasive that will pass through 30 to 100 mesh screen,
depending on etching speed and surface effect desired.

3. To adjust abrasive feed turn LAC-3 Aircap clockwise for
less feed, counter clockwise for more feed. Lock position
of aircap by tightening D-60 Locknut.

4. Air pressure of 30 to 100 lbs. is used depending upon
speed, texture and result desired.

5. With stencil design or mask properly placed on glass,
metal or other material to be treated, point LA Abrasive
Gun at the surface 2" to 6" from and directly above the
stencil. Pull trigger and spread abrasive evenly over the
part to be etched or blasted.
a. For a sharper line move gun closer to working surface.
b. Greater depth can also be obtained by continued

coverage of the part to be blasted, or by using sharper
abrasive.

6. For faster deeper cutting, or greater production, increase
air pressure and abrasive feed.
