Q. How is glass tile colored?

A. Glass tiles can be colored in a couple of ways.  In the first process, the pigments are mixed in with the molten glass, allowing the color to entirely permeate the body of the tile.  The second process involves a layer of pigment which is fused to the surface of the tile during the firing process.  Either way, glass tile will not fade, while remaining to be moisture-proof.


Q. Is the color of glass tile uniform?

A. There is a general uniformity from batch to batch in terms of dominant color. But there are shade variations to be expected between your sample and your order batch.


Q. Where is glass tile most commonly installed?

A. Glass tile is renowned for its versatility.  Because it is impervious to the effects of moisture, glass tile is a popular addition to bathroom areas and spa locations in commercial settings as well as residential ones.  Glass tile can be used as a wall tile to cover surfaces entirely, or as flourishes and trim pieces.  They can be used for shower stall floors, and as creative centerpieces to a room in the form of murals or as unique layouts that mix colored glass tiles in a mosaic pattern.  They can also be used in outdoor settings, like in pools or courtyards, and even as mosaic patterns on external walls.


Q. How does glass tile perform outdoors?

A. Because glass tile is non-permeable, it is highly suitable for a surface which needs to resist moisture.  Additionally, glass tile is frost proof as well as being heat, fire, and UV resistant as well.  They also resist sudden temperature changes.  In many ways, the addition of glass tile to an outdoor surface is one of the best means of protecting the overall structure of a property.


Q. What issues should I be aware of when preparing a surface for a glass tile installation?

A. Make sure that all substrates are level, dry, and clean.  This is very important for the long-term health of the structure and the overall performance and look of the glass tile you’ve chosen to install.  Sandpaper the area to clear it of any residual materials which might affect how well the tile will bond with the substrate.  Generally, glass tile will adhere to nearly any type of material – wood, metal, plasterboard, more.  The key to success, after the substrate has been prepared, is choosing the right kind of adhesive.


Q. What adhesives work best with glass tile?

A. One of the primary criteria when choosing adhesives for glass tile is the issue of trapped moisture.  The impermeability of glass tile often results in trapped moisture after a glass tile installation.  This can lead to problems down the line with your substrate, when mold growth becomes an issue which can affect the color of the glass tile, among other issues.  Sand-based thinset will limit this problem, as opposed to mastic.  When in doubt, seek the advice of local retailers who sell adhesives for tile. Read the instructions of all of the products you decide on, and always follow instructions on the packaging as carefully as you can.


Q. How long should I wait before subjecting glass tile to full immersion in water?

A. In the case of a glass tile installation for a pool bottom, bathtub, or shower stall, it’s generally advised that once the glass tile has been installed on a stable substrate, it’s a good idea to wait about 20 days to allow the adhesive and the grout to fully set before using the space.


Q. What should I consider when choosing glass tile for flooring?

A. The first thing to think about is the issue of slip-resistance.  Most glass tiles meant for flooring will be specified as such.  Ask us about the issues regarding slip-resistance, and let us know where you are thinking of installing glass tile.


Q. Can I purchase just one box of tile before I place my full order?

A. We’re unable to sell individual boxes of tile due to shipping costs. The cost to safely ship one box of tile can be more than five times the amount of the actual tile.

Q. What’s the best way of cleaning glass tile?

A. Glass tile is a very low-maintenance surface.  It is stain-resistant, and can be cleared of everyday household grime with the wipe of a damp cloth. In the case of limestone or calcium build-up, a solution of water and hydrochloric acid will clear tougher materials from the surface of glass tile.


Q. How long does glass tile last?

A. Glass tile is a very durable material with few limitations as far as wear.  With regular cleaning, your glass tile can last as long as your entire property.
