Wet Set method causes Glass tile Problems


Glass tile mosaics are without a doubt, the most beautiful finish available for swimming pools, spas and watershapes.  However, there are standards and procedures that must be adhered to, to ensure a successful installation.

First and foremost, you should obtain SPECIFIC installation instructions from the manufacturer of the glass tiles.  They should specify which products they endorse and recommend for their tiles.  If the instructions recommend a generic white cement and sand blend, seek specific pre-mixed product recommendations.  You do not want to risk an expensive glass tile job on such flimsy instructions.



Know the applicable standards.  While the Direct Set (aka: wet set or two-step) method of setting tiles may be okay for some stone and ceramic tiles, it is not permitted for glass tile.  Some foreign manufacturers still recommend it.  But, the 2005 ANSI A108.14-A108.16 standards are very precise about the acceptable methods of installing glass tiles.  The Direct Set Method is not one of them.  It is fast and inexpensive - that's why installers use it.  But consumers pay with issues like those shown above.



The Ceramic Tile Institute of America (CTIOA) and the Tile Council of North America (TCNA) also endorse the ANSI standards (ctioa.org/pdf/2008-8-12_Glass_Tile_Report.pdf).  These standards also have prescribed materials performance specifications and curing times for each phase of the installation.



While time consuming and labor intensive, properly installed glass tile mosaics will result in a spectacular finish that should last for generations.
