Hardie® Backer PRO
Why choose Hardie® Backer PRO?
Long-term durability starts behind the tile. Hardie® Backer PRO is the 100% waterproof cement board engineered to install and protect tile on the walls and floor in wet and high-moisture environments like showers, backsplashes, bathrooms, kitchens, laundry rooms, and mudrooms. When installed as directed using Hardie™ PRO Seam Tape and modified thinset, it creates an effective waterproof solution — no additional membrane or waterproofing treatment required. Proprietary built-in MoldBlock® Technology helps protect the board from mold growth.
100% built-in waterproof*
