Before you begin

For the typical do-it-yourselfer, the installation of Dumawall panels is a relatively easy project.

Read this installation manual in its entirety before you start. If you have doubts about doing this installation, you should contact a qualified contractor, carpenter or professional installer.

Preparation

Note:

The tiles should be laid flat for 48 hours in the area in which they will be installed with a minimum distance of 2-feet from the walls to adapt to the environmental conditions in the area. The ideal temperature before and during installation is approximately 70° F.

A sturdy support frame must be attached to uneven or damaged walls to ensure an even surface on which to attach the tiles.

  • 2” x 2” furring strips or lattice is recommended.
  • These supports must be installed in the opposite direction of the tiles (e.g. if the tiles are installed horizontally, then the supports must be placed vertically).
  • The distance between the supports should be a maximum of 12 inches.

With a smooth, even wall surface, Loctite® Power Grab Ultimate adhesive can be used to attach the tiles and no framework is required. The Dumawall tiles may be glued directly onto existing tiles, drywall, OSB or plywood.

  • This method is only suitable for dry surfaces free from dust and grease. For damp and uneven walls, we recommend the use of furring strips or lattice.
  • Apply the adhesive in a zigzag pattern onto the tile or the approved substrate. Keep adhesive 1-inch from tile edges and wipe off excess from tile face before adhesive dries.

Installation

The Dumawall tiles may be cut using a handsaw, table saw, or portable circular saw.

Place the first tile with side (A) facing to the right.

Then attach the tile using one of the following methods:

  • (A) on framing with nails through the tab at the top. For a perfect fit for the next row, make sure that the nail is completely flush with the tab.
  • (B) on a smooth surface like drywall, OSB or plywood using adhesive (see Preparation).

Connect the next tile along the cross-cut side (B) by fully inserting the tab into the groove.

Make sure that the tiles always fit each other properly along the length, so that the next row fits perfectly parallel. Create a full row this way by fitting the tiles via the end tab with nails or adhesive. Cut the tile to size at the end of the row. Attach the first row of tiles with 1-inch wood screws at the bottom if using a baseboard or cover base. If not covering with base, use adhesive to attach bottom of tiles.

Take the remaining piece (at least 12 inches long - enabling it to be fixed to the first support beam of the framework) of the cut tile and use this for the next row if needed.

You can install the tile in a “staggered” layout (A) or “stack bond” layout (B). The tiles can be placed vertically as well as horizontally. Complete the installation row upon row.

Finishing and Maintenance

Do not attach accessories like coat hooks, light fittings, mirrors, etc. directly to the tiles. Drill holes through the tiles and use suitable anchors to attach the accessories securely into the framing behind.

For installation in a shower area, around a bath or other very damp places, a bead of silicone sealant must be provided in the tongue and groove connection between the tiles themselves and between the tiles and support trims to ensure a completely waterproof joint. Also apply a silicon bead between the tile and the edge of the shower or the bath.

For edge treatment, you can use a 5/16-inch aluminum flooring edge trim for a professional edge look. These aluminum trims will need to be installed prior to, or at the same time as, installing the tiles.

Alternatively, color-matching caulk or clear silicone adhesive can be used to finish outside edges and/or inside corners.
