1. Containment & Environmental Protection

  • Ground Covering: Lay impermeable tarps or ground covers extending at least 25 feet from the blast area. Overlap seams by at least 1.5 feet. Minnesota Pollution Control
  • Ventilation & Sealing: Seal all doors, vents, fans, and windows within 50 feet of the blast zone. Use high-quality wind-resistant tarps (woven polypropylene) to block dust migration and avoid blasting in high winds. 
  • Neighboring Structures: If facing a neighboring building within 20 feet, hang a vertical curtain between the walls that is at least as tall as the shorter wall. Minnesota Pollution Control

2. Surface Prep (Pre-Cleaning)

  • Degrease: Sandblasting embeds oils and greases deeper into the substrate. Remove all oils, grease, and chemicals using solvents or commercial degreasers before you start blasting. De6c2c0d 3187 4291 B22f C854c8244897Vapor Honing Technologies
  • Debris Removal: Manually scrape or brush off large flakes of loose paint, rust, or debris. Vacuum the area so the surface is entirely clean and dry. E59bb2bd B396 428b 9c48 0762562f9b54Vapor Honing Technologies 
  • Protect Adjacent Items: Mask off areas you do not want blasted, such as glass, delicate fixtures, or moving machinery, using heavy-duty ducting tape and plywood or rubber shields.

3. Equipment Staging & Setup

  • Air Supply: Position your air compressor upwind to prevent it from ingesting abrasive dust.
  • Moisture Control: Install an industrial air dryer and moisture separator before the blast pot to keep media dry and prevent clogs. Sandblast Solutions 
  • Safety Restraints: Connect all air hoses using safety whip checks and locking pins to prevent violent hose whipping in the event of a coupling failure.
