Step 1: Cover the Seams

Cover the seams around the edges of any plywood patches in the floor with duct tape. This will keep the leveling compound from dribbling through the seams.

Step 2: Mix the Compound

Flip over the bucket of leveling compound to get the sand off the bottom. Roll the bucket on its side for 60 seconds to mix the compound, and then finish off the mixing process by using a drill with a paddle bit.

Step 3: Pour the Leveling Compound

Pour the leveling compound onto the low areas in the floor and allow it to level itself.

Step 4: Install the Cement Board

Once the leveling compound has dried according to the manufacturer's instructions, install cement board over the subfloor. Secure the cement board with special cement board screws, not drywall screws.
