  1. Observations on the Use of “Dust Free” Paint Stripping & Sanding Equipment 1. Paint Shaver 2. Paint Blitzer

  2. Paint Blitzer (drum grinder) Midwest Specialty Products Model Pb3000 Voltage: 110 RPM: 3450 Advised Vacuum CFM: 150 min. Paint Shaver (circular grinder) American International Tool Voltage: 110 RPM: 10,000 Advised Vacuum CFM: ?? Equipment

  3. Limitations of this Type of Equipment • Most require staging or a mechanical lift to be used effectively • Workers must be protected (respirators, etc.) until air monitoring says its safe • Quality HEPA vacuum with adequate CFM • Finish sanding always required to get tight spots, under clapboards, prepare for painting.

  4. Paint Blitzer • Very cumbersome, base unit weighs 40+ pounds, need a mechanical lift • Uses grinding sleeves, different abrasive grits for removal and finishing • Can’t remove paint from tight spaces at edges and under clapboards • Grinding sleeves require frequent replacement, they gum up with paint

  5. Paint Shaver • Lighter than Blitzer, easier to use overall • Hitachi circular grinder/sander modified with inner metal shroud and 3-sided tungsten carbide blades. • Blades should last for 5,000 s.f. • Hinged outer shroud allows access to tight areas

  6. Paint Shaver Field Observations • Requires two hands to use, necessitating staging or a mechanical lift for high areas

  7. Paint Shaver Field Observations • Takes some time and practice to operate the equipment properly and effectively.

  8. Paint Shaver Field Observations • Good technique is required to keep dust from escaping • Even using perfect technique, some dust always escapes

  9. Paint Shaver Field Observations • Requires smooth surface to operate properly • Works best if loose and flaking paint is knocked off by hand first • Nail heads have to be set or Shaver will rip them out, sometimes taking half the clapboard with it

  10. Paint Shaver Field Observations • Does a pretty good job of removing paint • Creates lots of concentrated lead waste and subsequent disposal issues • OSHA 1926.62 applies to any business where these tools are used.

  11. Practicality of Power Equipment • Lead is still present in bare wood surfaces • All sanding creates lead dust • Clapboards must be in good condition to withstand paint removal • Clapboard replacement would remove lead, allow installation of building wrap • The equipment is NOT “dust free”
