My floor guy screened my floors, used a tack cloth and vacuum (not
sure of which he did first) then put down polyurethane. There's dust
in the finish. I suggested he come back and screen, then vacuum and
tack, then wait a few days, then tack again and put down poly.
He said he could wait the few days, THEN screen, tack and vacuum and
then immediately put down the poly.
Is he right, or should he wait a second time?
If he is using waterborne polyurethane, I'd want him to sand, vacuum, go over
with damp cloth or tack cloth and then put down the finish ASAP. It's best to
have a fan drawing the dust out a window as the screening is taking place so
there isn't as much dust in the air. These new "grabber" mops are great for
getting all the dust up!!
If he is using oil base polyurethane, you'll have some dust specks no matter
when he puts the finish down.
who has applied as many as 7 coats of waterborne in one day.
