Tip: Make a portable dust screen
When remodeling several rooms at once make a portable dust screen. Build a frame from scrap pieces of 2x4s roughly the size of the doorways or hallways you're working on. Cover the frame with clear poly that extends about 2-3 inches from the top and sides to act as a flexible seal that won't harm your walls. Staple the poly to the frame and attach a short board horizontally on either side of the base of the frame. This helps to keep debris in a confined space so it's easier to clean up and it keeps dust out of your furnace filter.
