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 CFMFinish 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 dustClapboards must be in good condition
to withstand paint removalClapboard replacement would remove
lead, allow installation of building wrapThe equipment is NOT “dust free”
