Flexible Floor Patch & Leveler is a ready-to-use, latex-based product used to fill cracks, fastener or knot holes and level low areas in plywood subfloors or concrete surfaces. The floor patch and leveler will remain flexible allowing the plywood subfloor to flex without cracking the filled-in areas. It is ideal for filling and leveling surfaces prior to installation of carpeting, vinyl floor tile or sheeting, as well as ceramic or mosaic floor tile.
