Safe Removal Methods

Lead-based paint should never be removed using methods that generate excessive dust or heat, such as dry sanding, open flame burning, or using high-heat heat guns, as these can release hazardous lead particles into the air.

The safest removal techniques include:

  • Wet sanding or wet scraping: Moisten the painted surface with water mixed with a small amount of detergent to suppress dust. Use a scraper or sanding block gently to remove paint without creating airborne particles.
  • Chemical strippers: Apply EPA-approved, non-toxic chemical paint removers that soften lead paint for easy removal. Follow manufacturer instructions carefully and work in well-ventilated areas.
  • Encapsulation: For areas where removal is not feasible, apply a certified lead encapsulant to seal the lead paint and prevent exposure.

Cleanup and Disposal

After paint removal, meticulous cleanup is necessary to ensure no hazardous residue remains. Use a HEPA vacuum to collect dust and debris from all surfaces, including floors, walls, and windowsills. Follow vacuuming with wet wiping of all surfaces using disposable rags soaked in a lead-specific cleaning solution or a mixture of water and trisodium phosphate (TSP).

Dispose of all contaminated materials—including plastic sheeting, disposable PPE, paint chips, and chemical strippers—according to local hazardous waste regulations. Do not discard lead-contaminated debris with regular household trash.
