Surface Prep: Sanding
- Sanding Patched Areas or Imperfections
Sand using medium grit sandpaper to smooth and level patched areas or areas with imperfections in the previous paint film (bubbles, rough spots, peels or cracks). After sanding, wash the walls with a mild soap and water solution to remove sanding dust.
- Sanding to Degloss
Wash the surface first with a mild soap and water solution. Sand walls and trim with medium grit sandpaper to dull the surface and create a profile for the new paint to adhere. After sanding, wash the walls as described above to remove sanding dust.
Removal of old finishes by sanding, scraping, or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment, such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup.
