Seal Off Your Work Area
Remove all furniture and rugs in the room you're about to work in and cover floors with 6-mil polyethylene (poly) sheeting. Use duct tape to secure it to the floor tight to walls and at least 5 ft. beyond the room you're working in. Avoid taping it to baseboards or other trim if you're worried about damaging the paint. Turn off the furnace and then cover supply and return registers with poly and tape. Keep windows closed to prevent dust and chips from blowing around, and cover and tape off doors and other openings to keep dust contained to your work area.
