Frequently Asked Questions

1. Can I use glass mosaics outside?

Yes, most of the glass mosaics applications our company does are for exterior applications either to be used as murals, facades or swimming pools. It is composed of glass and does not absorb water or freeze.

2. Does the color fade with time or with sunlight (UV)?

No, most of our formulas are melted glass at around 1200 °C and the main composition is silica sand and the color is mineral oxides melted together at those high temperatures, so it resists time and the color is permanent in all the body of the mosaics.
We do have some collections that just have color on top (some metallic and translucent collections) where the pigments are just on the top of the tile and not in the entire body, but again is melted at a lower temperature to resist fading and time.

3. Can I use Glass tile on permanently submerged applications as in all-tile swimming pools?

Yes. Of our daily production, around 12,000 sq.ft  is produced for swimming pool applications and most are for all-tile pools. We have been specialized in glass mosaic for pools for nearly 65 years, so our products are very reliable and have very good performance.

4. Does glass tile have sharp edges that would be detrimental on a pool floor or spa?

The Kolorines glass mosaics have beveled edges and are designed to be used in pools, spas, and bathrooms, as well as bathroom floors. Before purchasing your tile for these applications, you should avoid tile with sharp edges or tile that would crack with temperature changes, producing sharp edges as well.

5. I have seen on some all-tile hotel pools in the Caribbean that some tiles come off. How can this problem be avoided?

It is very important to choose a correct installation method and installation materials, and most importantly, experienced installers. The Ceramic tile Institute of America (CTIOA) has some  good recommendations concerning methods and materials. Also, manufacturers of thin set adhesives (Laticrete, Custom, Mapei, etc.) if this method is chosen  should specify that the adhesives are for glass mosaics (does not absorb water) and for submerged applications. Regarding installers not certified, we recommend to test their skill in a small area before they do the entire pool.
The design of the tiles are also a factor that impacts the detachment of the tiles. Kolorines designed a shape (edges on the perimeter of each tile ) that once grout is applied creates mechanical resistance to come off.

6. Are the tiles affected by chemical deterioration from regular products used in the pools like chlorine, soda, ash, acid cleaners, etc?

No, chemical products like muriatic acid and caustic soda used to balance the pH or products to clean the pool does not affect the mosaics at all. Our glass tile mosaics have the same physical and chemical properties as glass- they are just affected by the rarely used hydrofluoric acid.

7. Are glass mosaic tiles mounted on sheets?

Specifically, small sizes 2″, 1″, 3/4″ tile sizes come mounted on sheets.
Most of our mosaics are presented in sheets of approximately one square ft. They come paper face mounted, but plastic film and dot mounted (pvc edge mount) are available by request.
There are many mountings for mosaics, Mesh is very popular but the most recommended methods for swimming pools (permanently submerged applications) are on paper or plastic film since they provide 100% access to the bonding surface of the mosaic with the thin set adhesive or the mortar bed and cement.

8. Can you help me with installation?

Yes, we can provide advice on installation methods, materials and even recommend a team of installers.

9. Which installation method do you recommend?

We recommend primarily two methods of installation: the thin set method or the mortar wet set method. Both described in the Builder Resources section of this site.
