Observations on the Use of “Dust Free” Paint Stripping & Sanding Equipment 1. Paint Shaver 2. Paint Blitzer Equipment 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: ?? 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. 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 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 Paint Shaver Field Observations Requires two hands to use, necessitating staging or a mechanical lift for high areas Paint Shaver Field Observations Takes some time and practice to operate the equipment properly and effectively. Paint Shaver Field Observations Good technique is required to keep dust from escaping Even using perfect technique, some dust always escapes 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 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. 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”
