This wall scarfer was initially developed over 20 years ago for smoothing out the side walls of foam insulated wine tanks w/3# density foam.  We have been asked to create a unit that doesn’t require a long air hose or larger than average air compressor so we developed these electric units.  This 110V grinder powered unit makes easy work of smoothing out over filled 2# density wall insulation foam.  As with the original units this unit is tough and simple to use.  Using standard blades it is easy on the 2x4 wood studs and does quick work at removing excessive foam.  Comes with 2 sets of heavy duty blades.
