First you need to determine if you are installing loose Glass Tiles or a sheet mounted Glass Tile Mosaic. If you are installing a sheet mounted Glass Tile Mosaic, you need to determine how the individual Glass Tiles are mounted on the Glass Tile Mosaic sheet:
- Paper / Clear Face Mounted Glass Tile Mosaic or a
- Netting Rear / Back Mounted Glass Tile Mosaic.
INSTALLING PAPER / CLEAR FILM FACED GLASS TILE MOSAICS
With a Paper / Clear Face Mounted Glass Tile Mosaic, the glass tiles are mounted with the paper / clear film on the top face of the Glass Tile Mosaic.
IMPORTANT NOTE: Both Paper and Clear Film mounted sheets MUST be installed Paper (or Clear Film) Side UP facing you.
INSTALLING NETTING REAR / BACK MOUNTED GLASS TILE MOSAICS
With a Netting Rear / Back Mounted Glass Tile Mosaic, the glass tiles are mounted with the netting on the back of the Glass Tile Mosaic and you install the Glass Tile Mosaic with the netting side down..
Glass Tile and Glass Tile Mosaics require the use of a Premium Thinset Mortar to install the Glass Tile and Glass Tile Mosaics with.
Setting material products are available through tile dealers, home centers, and major setting material companies. Glass Tile Information does not endorse any particular setting material or setting material manufacturer. Below is a list of products commonly used for installing glass tile. Consult your installer or local tile dealer to determine the most suitable setting material for your particular application.
Laticrete: 254 Platinum Multipurpose Thin-Set Mortar. No admixture is necessary just add water. www.laticrete.com
Mapei: Kerabond Premium Dry-Set Mortar (Ker 102) mixed with Keralistic Mortar Admix (Ker 310)
Mapei: Adesilex P10 (bright white) non sag mortar for glass tile. Mix with water or Keraply. www.mapei.com
TEC (H.B. Fuller): Super Flex Premium Performance Universal Latex-Modified Thin-Set Mortar. No admixture is necessary. www.tecspecialty.com
Mastic is NOT recommended for installation of glass tile and glass mosaic tile, particularly in wet areas such as showers. Bond strengths are lower than those of recommended setting materials. Mastic does not properly cure when used with impervious materials such as glass and may yellow behind clear or translucent tile.
THE FOLLOWING ARE SURFACES THAT ARE ACCEPTABLE FOR INSTALLING GLASS TILE AND GLASS TILE MOSAICS ON TO:
These surfaces must be properly prepared before installing your Glass Tile and Glass Tile Mosaics.
Surface preparation is a key factor in the success or failure of your Glass Tile and Glass Tile Mosaic installation.
Although a surface may be listed as acceptable, if it is not properly prepared, loss of bond will occur. Also, all acceptable surfaces may not be acceptable for all applications. Consult manufacturer or installer.
- Concrete, mortar beds, masonry
- Cement backer boards such as Wonder board
- Exposure 1 or APA exterior grade plywood
- Existing ceramic tile or terrazzo
- Asbestos-free vinyl flooring
- Waterproof membranes—check with manufacturer
THE FOLLOWING ARE SURFACES THAT ARE NOT ACCEPTABLE FOR INSTALLING GLASS TILE AND GLASS TILE MOSAICS ON TO
These surfaces, even if properly prepared, will not provide a bondable or stable surface for your Glass Tile or Glass Tile Mosaic installations. Under no circumstances should Glass Tile or Glass Tile Mosaics be bonded directly to these surfaces:
- Particle, wafer and structure board
- Hardwood or Parquet floors
- Luan plywood
- Sponge or cushion-backed or asbestos-containing vinyl flooring
- Self-adhesive vinyl squares
- Wall coverings
- Unprimed plaster
- Lightweight concrete
HOW TO CUT GLASS TILE AND GLASS TILE MOSAICS
Small format glass tile (5/8", 3/4", 1") are best cut with specialty glass mosaic tile cutters, available from tile or craft dealers. Tile may also be set on backer board, and then cut to size with a wet saw. The cut edges can be very sharp and should be smoothed with carbide paper or a "white stone" which are also available at tile dealers.
HOW TO REMOVE THE PAPER / CLEAR FILM FROM THE FACE OF THE GLASS TILE MOSAIC AFTER IT IS INSALLED
Wait for the thinset to bond to the Glass Tile Mosaic. After the thinset has cured and the Glass Tile is securely mounted to the surface, you can Begin wiping down the paper with a damp sponge and warm water. Rub lightly to avoid disturbing the tile placement. The paper facing will begin to darken as the water is absorbed. After 2-3 minutes, test a corner of the paper sheet. Pull lightly downward at an angle instead of straight out.
Clear Film Face:
Wait for the thinset to bond to the Glass Tile. After the thinset has cured and the Glass Tile is securely mounted to the surface, you can simply peel the clear film away from the glass tile.
GROUTING YOUR GLASS TILE AND GLASS TILE MOSAIC
Grout is the material used to fill the spaces between the individual Glass Tiles and Glass Tile Mosaics.
Grouts are available in many colors. While color is important to the final finished look of the Glass Tile and Glass Tile Mosaic installation, it has little effect on the functionality of the grout. The purpose of grout is, simply, to fill the joints between the Glass Tiles and becomes a permanent, integral component of the finished installation
There are basically two different types of Grout you can buy:
- Cement Based Grouts
- Epoxy Based Grouts
Cement Based Grouts
Cement Based Grout is basically colored cement and is available in sanded or non sanded depending on the width of your grout joint.
If your grout joint is Smaller than 1/8", Non Sanded Grout is generally recommended.
If your grout joint is Larger than 1/8", Sanded Grout is generally recommended
Most Glass Tile and Glass Tile Mosaic installations use Cement Based Grout. This type of grout is porous and should be sealed after installation to prevent the color from staining. Cement Based Grout should be sealed with a penetrating / impregnating sealer (often called grout sealers) which does not contain silicone, as silicone can shorten the useful life of the sealer.
Epoxy Based Grouts
Epoxy Based Grouts are chemically cured and are acid and stain resistant making it an excellent choice for use with Glass Tile and Glass Tile Mosaics.
Epoxy Based Grouts are becoming more popular because they do not require a sealer and are virtually maintenance free. Below is information on Laticrete SpectraLOCK PRO Epoxy Grout.

HOW TO REMOVE THE GROUT FROM THE SURFACE OF THE GLASS TILE AFTER IT IS DRY.
Use a nylon bristle brush, a sponge, and warm water to clean any residue from the tile surface. A hard surface cleaner can be used for more difficult cases. Ideally, the grout should be cleaned to your satisfaction before it has completely cured. A small area should be tested first to make sure the process will not damage or scratch the Glass Tile or Glass Tile Mosaic surface.
Note: some glass tile and glass tile mosaics have small pinholes or crazing on the surface which may collect grout. Any grout will collect in these small surface pinholes, but a little extra time spent cleaning the surface while the grout cures will significantly reduce the amount of visible grout left on the surface. Also, a matching grout color will tend to be less noticeable on the tile surface than a contrasting grout color.
