Concrete: one pass at a time
A surface cleaner is a spinning bar under a round hood.
It holds an even distance off the slab, so the finish comes out even too.
A bare wand in a hurry is what leaves zebra stripes.
Foam goes on first and sits long enough to work.
Then the passes overlap until the whole panel is one color.
Oil stains and rust may fade rather than vanish, and we will tell you that up front.
