I like the "saw dust better than the synthetic powder. While both are difficult to remove, the powder seems much harder due to particle size.
and you guys are worried about a few ounces of Encap solution spread over several hundred feet.
Weigh how much compound you spread and how much you recover. But don't worry...it keeps working for you....until it dries out and decides to join the other side.
Seriously vacuuming is where the real work is being done. Don't rush the vacuuming!
with the brush pro i can retrieve nearly 100% of the compound. only exception is if it gets right up against an edge, other than that it all goes right into the bins.
