Dumawall Dusky Shale Waterproof PVC Tiles

Dumawall Dusky Shale Waterproof PVC Tiles are 100% waterproof interlocking wall tiles that replicate the look of real stone or marble tile without grout, mortar, or the risk of moisture penetration. Deep grey-brown with subtle layered texture reminiscent of natural shale. A sophisticated, grounding colour that anchors the room and works as a feature wall or a full room application. Panels interlock with a click-fit system and install directly over existing tiles, drywall, or any flat wall surface. No special tools or contractors required. Available at Windsor Plywood locations across Canada.

Common Uses

Dusky Shale is popular for feature walls, shower surrounds, and spa-inspired bathrooms where a darker, more dramatic palette is the design intent. Dumawall tiles are also used for kitchen backsplashes, laundry room walls, and commercial washroom surfaces where waterproof, easy-to-clean wall cladding is required.

Pro Tips

• Acclimate tiles in the installation room for 48 hours before installing. Maintain a room temperature around 20°C (68°F) during installation for best results.
• When installing over existing ceramic tiles, ensure the old tiles are firmly bonded to the wall and the surface is clean and flat. Use a PVC-compatible adhesive or the recommended Dumafix adhesive.
• Apply silicone sealant in the tongue groove joints for shower and direct-water-contact installations. Standard room installations (kitchen backsplash, accent walls) do not require sealant in the joints.
• Cut tiles with a fine utility knife (score and snap) or a fine-tooth saw. No wet cutting or tile cutter required.

Frequently Asked Questions

Can I install Dumawall in a shower?
Yes. Dumawall tiles are 100% waterproof and suitable for shower walls. Apply silicone sealant in the interlocking joints for shower installations to prevent moisture from reaching the wall behind the tiles.

Do I need to remove my old tiles first?
No. Dumawall installs directly over existing ceramic tiles, provided the old tiles are secure and the surface is reasonably flat. This eliminates the mess, noise, and cost of demolition.

How do I clean Dumawall tiles?
Wipe with a damp cloth and a mild household cleaner. Do not use abrasive cleaners, scouring pads, or solvent-based products. The smooth, non-porous surface resists staining and mildew buildup.
