CONTAINMENT
To capture the blasting byproducts use heavy plastic or a tarp. Lay out your plastic and weigh the corners down, placing
your project in the center. You can sweep up media or use simple curtains or barriers.
MASKING
Mask off any glass, chrome, rubber seals, wiring, electrical, or moving mechanical parts and anything else that looks
delicate or like it shouldn’t have water and grit inside it. Tape works the best for protecting small parts and pieces.
BLAST PATTERN ADJUSTMENTS
It is important to use the proper nozzle to achieve the best blasting results. Nozzle size is based on air compressor size.

the water evaporate to sweep or vacuum.
Containment, Masking, and Blast Pattern Adjustments
BLAST WET, DRY, OR WITH SODA (AIR DRYER AND COOLER REQUIRED)
To prepare your machine for dry blasting:
1. Blast all media and water out of machine.
2. Remove fill cap.
3. Turn on air dryer and cooler.
4. Open air inlet valve halfway and let air circulate through machine for 5-7 min or until completely dry.
5. Put fill cap back on machine and pressurize tank.
6. Run air through the machine just like you were blasting for 2-3 min.
7. Shine light in machine to be sure all moisture is gone from the bottom.
8. If no moisture, fill with 1 bag of dry abrasive. Fill the remainder of the way.
Note: Using media such as plastic bead, walnut shell, corn cob, or soda requires dry blasting.
