Whenever you're remodeling, it's important to protect any uncarpeted floors from demolition debris and dropped tools. When canvas drop cloths aren't enough, I use 4 x 8-ft. sheets of 1/8-in. tempered hardboard, commonly called Masonite. Start by thoroughly vacuuming the floors so grit doesn't scratch the flooring under the hardboard. Then cut and lay down the hardboard and duct-tape the pieces together at the seams. If you'll be running the HVAC system during the remodel, be sure you don't cover grilles or registers. Finally, seal around the perimeter with masking tape so grit can't get underneath the hardboard at the edges. A sheet of 1/8-in. hardboard costs about $5 at home centers. — Gary Wentz, Editor-in-Chief For more on removing walls and windows, as well as other demolition tips, go to
