Installation Constitutes Acceptance.



modwalls® CorkDotz™ tile is suitable for both interior and exterior wall and floor applications in both wet and dry areas.

Preparing the existing surface is the most critical task of any tile installation. The tile must be placed on a rigid, level, plumb and structurally sound surface to avoid problems. The surface should be clean, dry and free of contaminants that could prevent a good bond.

The recommended substrate is a cement backer board such as HardieBacker. Gypsum board may also be acceptable for interior dry installations only.



There are different “levels” of acceptable adhesives depending on where you would like to install the tile.

  • If you install modwalls® CorkDotz™ on a dry wall, you can use rubber cement for your adhesive
  • If you install modwalls® CorkDotz™ on a dry floor, you should use a stronger adhesive, like a mastic
  • If you install modwalls® CorkDotz™ on a wet floor, you should use a modified latex thin set for adhesion



The necessary tools for tiling are: Rubber Trowel, Roller or Sponge, Adhesive, Sanded Grout, Polyurethane, Utility Knife.


Remove the tile from its packaging and let it acclimate to the room you are installing it in. It should acclimate for 48 hours before installation.
Evenly apply appropriate adhesive over the prepared cement substrate.

Carefully lay out and place each sheet of modwalls® CorkDotz™ next to one another on the adhesive. Each sheet can easily be cut and shaped with a utility knife. Before grouting, allow the adhesive to dry for the timeframe recommended by the manufacturer. Thin-set, for example, will cure/dry in 24-48 hours.
Evenly distribute a sanded grout with a high quality rubber trowel, making certain that all joints are completely filled. The finished joints should be uniformly smooth without any voids, pinholes or low spots.

Finish the installation of modwalls® CorkDotz™ by applying an even amount of polyurethane or miniwax with a roller or sponge.
Beware of Grout Haze:
Grout haze is a very thin layer of grout which has been allowed to dry on the surface of the tile. There will be some grout that sticks in the natural indentations of the cork and can’t be removed. This is part of the look when using a natural material. The surface of the cork is pre-sealed with polyurethane which will reduce the amount of grout that sticks to the surface of the cork. You can also scrub the surface of the cork with a brush to remove some of the grout that is sticking in the natural indentations. Keep the brush parallel to the surface of the cork so that you don’t brush out the grout from between the tiles.
Cutting/Drilling CorkDotz™:
      • You can cut CorkDotz™ with a utility knife. Use a metal edge to ensure a straight cut.
      • Any wood drill will be sufficient to drill through modwalls® CorkDotz™ tile.
Cleaning CorkDotz™ Tile:
      • A damp sponge or mop is typically sufficient to keep this tile clean.
      • Non abrasive glass cleaners can also be used effectively.
