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.
FOR SHOWER, TUB OR DIRECT WATER ENVIRONMENTS. Although DumaWall tiles are 100% waterproof when used with DAP Kwik Seal Ultra in the seams, we recommend you follow your local building codes for wet environments like shower and tub enclosures. We recommend a 100% waterproof substrate that will prevent water from getting behind potentially unsealed areas that would cause mold or other damage.
Acceptable waterproof substrates are:
- Existing ceramic tile walls. No additional preparation required.
- Installation over waterproof substrates, such as Cement Board®, Schluter Kerdi Board®, GP Densheild®, Johns Manville GoBoard®, Hardiebacker®, Fiberock® and equivalent products. Always follow manufacturer’s installation instructions to create a waterproof enclosure.
FOR BACKSPLASH, LAUNDRY OR OTHER DAMP ENVIRONMENTS. Although DumaWall tiles are 100% waterproof when used with DAP Kwik Seal Ultra in the seams, we recommend a moisture-resistant substrate for damp environments like kitchen backsplash, bathrooms or laundry areas. Use a moisture-resistant drywall such as Greenboard® or Purpleboard®. Follow manufacturer’s directions and your local building codes.
