Specialized grout can sometimes be required by Artists when doing 3D Mosaics or other Outdoor Mosaic Projects. One such project was an Artists project in Venice Italy. The gold glass mosaic needed a grout that didn’t distract from the beauty of the glass. The grout needed to compliment, so the artist selected Crystal Glass Grout(R) with the addition of Gold Shimmer to give a depth and sparkle to work with the glass. From a function standpoint on outdoor projects thermal expansion and contraction can play large a role in how well the finished project stands up to the elements. No worries here Crystal Glass Grout and our other products stand up to the elements in any environment.
