The Secret to Leveling Subfloors
I do a lot of remodeling, and it’s often necessary to level uneven floors with self-leveling compound. The product is anything but self-leveling, though, so I find the high point of the floor and drive a 15⁄8-in. tile backer or drywall screw nearly flush to the subfloor. Then using a spirit level or laser, I work across the room, driving additional screws at the same plane as the first to provide level reference points for the depth of the pour. I then use a long-handled squeegee to make the compound flush with the tops of the screws. Filling the heads of the screws with modeling clay or plumber’s putty lets me remove them later.
