READ this entire installation guide before beginning your installation. ACP is not responsible and will not be held liable for project failures if installation guidelines are not followed. ACP recommends that you install these tiles over an existing substrate to ensure proper structural integrity. DumaWall panels are not intended to be attached to raw concrete, poured concrete walls or concrete block basement walls. Appropriate substrates in a dry environment would include framed walls with existing tile, drywall, cement board, OSB, or plywood. DumaWall panels must be attached to structures that comply with your local building codes and have incorporated appropriate moisture abatement measures.
In a wet environment, such as a tub or shower area, you can use Green board (water-resistant drywall), Hardiebacker®, Tile backer board, Cement board, Go Board, Kerdiboard®, Durock®, DensSheild®, Fiberock®, Permabase®, Wonder board®, and Schluter®.
