Dumawall Dark Gray Slate Waterproof PVC Tiles

Dumawall Dark Gray Slate 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. Rich charcoal grey with natural slate texture. The darkest colour in the Dumawall range, Dark Gray Slate creates a bold, modern statement and provides strong contrast against white fixtures and light countertops. 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

Dark Gray Slate is best used as a feature wall, shower surround, or accent where contrast and drama are the design intent. In small spaces, balance with lighter elements to avoid a heavy feel. 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.
