These instructions will serve as a guideline for the installation of our Crave line of glass tile. We advise you to hire a licensed professional tile installer who is experienced with the installation of glass tile.


Crave glass tile is made of clear glass with colorant kiln fired onto the back of the tile. It is important that you inspect your entire order to ensure that it is acceptable before installation. If for any reason you are dissatisfied with your order please contact us immediately at 877-439-9734 or

Installation Constitutes Acceptance.


modwalls® Crave glass tile is suitable for both interior and exterior wall 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.


Per ANSI 118.4 compliance, we recommend using a white, thin-set mortar modified with polymer or latex.


The necessary tools for Crave glass tile installation are: Tile Float, Large Bucket, 3/16" V Notched Trowel, 1/16" Tile Spacers, Sponge, Lint Free Cloth and a Wet Saw with a Diamond Blade appropriate for cutting glass tile. (Crave glass tile 3x6 or larger sizes may be successfully cut using a glass score and snap method).


  1. Mix the powdered thin-set mortar with latex additive in bucket. Stir and add more liquid until it reaches the consistency of peanut butter.

  2. Per instructions on thin-set package, allow mixture to slake for 10 minutes.

  3. Apply to wall evenly with the v-notched trowel. Work in sections of 2 square feet at a time. Smooth out trowel ridges before applying tile.

  4. Apply tile to wall starting in the middle of installation area and working outward.

  5. Apply tile spacers between sheets for consistent grout lines.

  6. Remove spacers and any thin-set which may have pushed up into the grout joints with a wooden stick before the thin-set has cured. Allow thin-set to cure/ dry at least 48 hours before grouting.

  7. Apply a grout release such as Custom Building Products TILELAB® SURFACEGARD® SEALER to the textured surface of Crave tiles to facilitate grout cleanup. Spread the grout using a rubber grout float and work diagonally across the tiles, making sure that all the grout joints have been filled.

  8. Let grout dry 10-20 minutes. Using a slightly damp sponge, wipe diagonally across the tile to remove the grout film from the surface of the tile.

  9. Wipe tile with a lint-free cloth as the final step, buffing away all residual grout from the surface of the tile.


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. During installation the grout must be completely wiped from the tile surface and then the tops of the tiles buffed with a soft cloth to remove any residual grout film. Once the grout dries overnight there is little that can be done to remove grout haze, aside from washing the tile with one of the commercial acid grout haze removers.

Cutting/Drilling Crave Glass Tile:

  • The recommended cutting method is by wet saw with a new diamond blade designed specifically for cutting glass. For tile size of 3”x6” or larger the glass score and snap method is also effective.
  • Make cuts onto the back side of the tiles (the mesh-backed side).
  • Edges which have been cut should be smoothed with diamond hand pad or other similar smoothing tools.
  • If it is necessary to drill holes in the tile we recommend doing so with a low speed drill equipped with a diamond tipped core bit BEFORE installation. Water must be sprayed on the surface and drill bit continuously during drilling.

Cleaning Crave Glass Tile:

  • A damp sponge is typically sufficient to keep this tile clean.
  • Non abrasive glass cleaners can also be used effectively.
