Strategies for Controlling Drywall Dust
I’m in the process of finishing a 3rd story walk-up attic, and am having the drywall installed in the next week or two. A ducted heat-pump air handler resides in this attic, along with all the ductwork. I’m planning to cover it with a plastic sheet and seal up the attic supply and return vent, which are already connected to duct but the duct is not yet connected to the air handler plenums (the air handler will serve both the second and third floors of the house).
I’m also planning to tape an HVAC filter to a box fan, set the box fan in an open window, and also open another window at the other end of the attic, and have the fan exhausting air the entire time drywall is being cut/sanded. I would think this will at least keep most of the dust on the side of the attic that the fan is running. But if I do this, will I get a fine coating of visible white drywall dust on the portion of my porch roof that is below the window that will be exhausting attic air? Bad idea?
Any thoughts or advice would be appreciated. I know this is going to be a dusty/dirty part of the project but I want to take reasonable steps to minimize the pain!
