I need to grind an apron or slope area across a garage door opening. The
opening originally had storefront glass in it, so the edge of the slab is
flat.
I'm wanting to go about an inch deep at the slab edge, so the slope will be
about 1" in 7 or 8" setback.
I figure to rough away a lot of the material first with an electric hammer
and a 3" wide bit. I tried cutting grooves, but I think that adds a lot of
time & dust, but doesn't speed up the chipping process all that much.
Will a concrete grinder, the kind that looks like a floor buffer, be
difficult to control on the roughed slope area?
thanks,
bill
