10 Blasting Bullets

10 quick abrasive blasting tips:

Nozzle size determines the air requirement (CFM), not the pot size.
Pressure systems are more efficient than siphon or gravity fed blasters.
More air is always better.
DRY AIR: Use a moisture separator on the blaster and cooler on the compressor.
Ceramic nozzles are inexpensive but carbide nozzles last much longer.
It’s rare to blast above 110 PSI – typical is 80-90 PSI.
Ear plugs are helpful, especially if you are near the compressor.
Avoid using a longer blast hose than is necessary. A longer air hose is preferred.
Proper protection is important, especially an air supply helmet in a closed or contained area.
DO NOT blast with silica sand. There are plenty of ‘healthier’ alternatives that might even work better.
Bonus Tip: Expect a loss of 5 PSI per 50 feet of air and blast hose.
