Preparation Before Sandblasting
Before sandblasting, items should be clean, dry, and free from oil, grease, or loose parts. Mask off any areas that shouldn't be blasted. Proper prep ensures a smooth, effective finish and protects both the item and equipment.
What Not To Do
-
Don’t bring in parts caked in mud, oil, or thick grease.
-
Don’t expect precision work on hidden or masked areas unless discussed.
-
Don’t bring sealed parts with bearings or electronics unless they're disassembled.
Pre-Blasting Prep Steps
-
Degreasing:
-
Use a solvent-based degreaser or hot wash tank to clean oils and contaminants.
-
-
Masking (if needed):
-
Mask off any areas that shouldn't be blasted using high-temp tape, rubber plugs, or caps.
-
-
Inspection:
-
Check for damage, cracks, or weaknesses in the material—blasting can make existing damage worse.
-
How Items Should Be
-
Clean of Oils and Grease:
Wipe down or degrease parts to remove oil, grease, or heavy dirt. Media doesn't work well on oily surfaces. -
Loose Parts Removed:
Remove bolts, clips, bearings, seals, gaskets, or rubber/plastic parts that shouldn’t be blasted. -
Dry Condition:
Items should be completely dry. Moisture can clog blasting media and cause rust.
