We are dusting a 28x48 crawlspace using the dustin mizer and delta dust. The duct work is under house but covered with plastic sheeting on underbelly (double-wide manufactured home). I see that directions indicate to turn off fans, etc and close vents. How long should I allow the dust to settle before I turn it back on?
Depending on how heavy you apply the dust will play some part in it, but usually you can allow the dust to settle for at least a few hours and it would be fine to resume normal use of the ducts since it is covered by the sheeting.
