DumaWall offers a versatile and waterproof solution for wall installations in wet environments such as bathrooms, showers, and laundry rooms. Designed for ease of use and durability, DumaWall panels and tiles are ideal for DIY enthusiasts and professionals alike. This guide provides a detailed breakdown of the installation process, including substrate preparation, tools required, adhesive and sealant recommendations, and best practices for ensuring a long-lasting, waterproof finish.
Preparing the Surface for DumaWall Installation
Before installing DumaWall panels or tiles, it is essential to prepare the surface to ensure proper adhesion and waterproofing. According to the installation documentation, DumaWall is not intended for use on raw concrete, poured concrete walls, or concrete block basement walls. Instead, suitable substrates include framed walls with existing tile, drywall, cement board, OSB, or plywood. These materials must comply with local building codes and incorporate appropriate moisture abatement measures.
For environments where water exposure is frequent—such as showers and tubs—a waterproof substrate is strongly recommended. Acceptable waterproof substrates include Cement Board, Schluter Kerdi Board, GP Densheild, Johns Manville GoBoard, Hardiebacker, Fiberock, and equivalent products. For less wet environments like kitchen backsplashes or laundry areas, moisture-resistant drywall such as Greenboard or Purpleboard is advised.
Regardless of the surface type, it is crucial to clean and prepare the wall before installation. If installing on an existing wall, it should be cleaned with a degreaser to remove any contaminants that may affect adhesion. The surface should also be level, true, and free from dust, grease, wax, or other debris. Glossy surfaces should be lightly sanded to improve adhesion.
Tools and Materials Required for DumaWall Installation
To install DumaWall panels or tiles, a range of tools and materials are necessary. The manufacturer provides a list of recommended tools and products to ensure a smooth and efficient installation.
Tools
- Hole saws: For cutting holes around fixtures or outlets.

Adhesives and Sealants
- Dumafix PVC Glue or Sikaflex 123 MS: These adhesives are recommended for bonding DumaWall panels to the substrate.
- Waterproof and antifungal sealant: A bead of sealant must be applied in each seam between panels, especially in wet environments such as showers. The recommended sealant is DAP Kwik Seal Ultra for U.S. customers and Kwik Seal Plus for Canadian customers.

Dry Layout and Tile Placement
Before applying adhesive, it is important to perform a dry layout. This step ensures that the panels or tiles are square and true, and highlights any areas where adjustments or trimming may be necessary. A dry layout also helps to avoid unsightly off-cuts by arranging panels or tiles with equal margins.
Dumawall+ tiles may be laid in either a stack or stretcher pattern configuration. Panels or tiles should be laid from right to left to ensure that the tongue-and-groove interlock is correctly engaged. This method ensures that the panels are securely connected and properly aligned.
If the wall or ceiling is not perfectly square, adjustments can be made during the dry layout phase. This is especially important in older homes or spaces where alignment may not be perfect. After completing the dry layout, any necessary trims or adjustments should be accounted for to ensure a seamless finish.
Installation of DumaWall Panels and Tiles
Once the dry layout is complete and the surface is prepared, the installation process can begin. DumaWall panels are designed to be installed by the average DIYer and are easy to cut to size using a saw (manual or electric) or a utility knife. The manufacturer emphasizes that the panels are not intended to be painted, but if painting is desired, it is recommended to consult with a paint department for proper primer and paint for good adhesion.
When installing in wet environments such as showers, it is essential to apply a bead of sealant in each seam between panels. The recommended sealant is DAP Kwik Seal Ultra, which ensures a completely waterproof joint. Additionally, a line of silicone sealant should be applied to the tongue and groove connection between panels, as well as between the panel and the edge of the shower or bath, and on inside corners.
For a shower niche or shelf, the manufacturer provides a specific installation guide. DumaWall panels can be used to create a niche or shelf in a shower as long as all connecting joints are sealed with a waterproof sealant. Horizontal panels should be installed at a slight angle (under 10 degrees) to allow water to slide off the surface rather than resting on it.
Post-Installation Steps and Maintenance
After the panels or tiles are installed, it is important to complete the final steps to ensure a durable and waterproof finish. These include:
- Installing plumbing fixtures and accessories: Any plumbing fixtures such as shower heads, faucets, or accessories should be installed at this stage.
- Caulking around the bottom and other necessary areas: Apply caulk along the bottom of the tiles where they meet the tub, as well as around accessories and plumbing fixtures. This step is crucial to prevent water from seeping into gaps and causing damage.
- Removing protective film: The panels and tiles are supplied wrapped in a protective film, which should be removed only when ready for installation. This film helps protect the surface during transport and storage.
Maintenance and Care
Proper maintenance is essential to ensure the longevity of DumaWall panels and tiles. The manufacturer recommends following the product’s care and maintenance instructions for detailed information. Regular cleaning with mild soap and water is typically sufficient to maintain the appearance and performance of the panels. Avoid using abrasive cleaners or harsh chemicals, as these can damage the surface.
Addressing Common Installation Questions
The manufacturer provides a list of frequently asked questions to address common concerns and clarify the installation process.
Can DumaWall be used in a shower or tub? Yes, DumaWall is 100% waterproof when used with DAP Kwik Seal Ultra in the seams. However, it is recommended to follow local building codes for wet environments and use a waterproof substrate to prevent water from getting behind unsealed areas.
Is it necessary to grout DumaWall? No. Grouting is not necessary as DumaWall already has a manufactured grout line built in. The gaps between panels are designed to be sealed with a waterproof sealant.
Can DumaWall be painted? While it is possible to paint DumaWall, the panels are not intended to be painted. If painting is desired, it is recommended to consult with a paint department for proper primer and paint for good adhesion.
How do I remove a single tile or a few tiles? If it is necessary to remove one or more tiles, the process should be done carefully to avoid damaging the surrounding tiles. Specific tools such as a utility knife or scribing knife may be used for this purpose.
Can DumaWall be used in a niche? Yes. The manufacturer provides a specific installation guide for using DumaWall in a niche or shelf within a shower.
