Organic adhesive is not an appropriate setting material for Lunada Bay Tile Glass Tiles in wet areas, such as showers or bathtub enclosures.  

Also, some organic adhesives may yellow behind clear or translucent tiles.

Organic adhesive does not cure, as do cementitious based products.  Adhesives dry and bond when exposed to air, given sufficient time.  As the adhesive first begins to dry and set at the edges, on larger glass tiles this will seal off the back of the tile, like putting a lid on a can.  Impervious materials, such as glass mosaics, can only properly set when installed using polymer-modified cementitious or epoxy based mortars. Again, it is important to note that time is required for the adhesive to set properly.

Use sanded grouts for all Lunada Bay Tile Glass.  Non sanded grout joints have a recommended maximum thickness is 1/8 and for sanded they begin at 1/8 thickness.

Lunada Bay Tile recommends polymer-modified sanded grout or even modified epoxy grout.  Follow manufacturer's recommendations for preparation and use.

It's important to note that all glass and sand are both primarily made up of quartz or silica materials. The sand within the grout should be carefully applied, not to scratch the surface.  The cementitious sanded grout should not be mixed too dry, making it necessary to aggressively pack gritty grout into the joints.  Also, it cannot be too wet so that it will run.  Mix it to a consistency of butter so that it can be shaped and easily fill the joints without force.  The acrylic or latex materials in polymer-modified grouts help to encapsulate the sand making it less gritty.  We recommend adding a latex admix to standard sanded grout, use an already polymer-modified dry mix grout powder, or use a modified epoxy grout ­ for a full, flush grout joint.
