Mosaic tiles come in a variety of colors, styles, sizes, and materials. We stock lots of stunning glass mosaics along with marble, granite, travertine and pebble tiles.Most mosaics come on a mesh for easy installation. Each sheet is typically 1 square foot. Be sure to use appropriate adhesive for the mosaic whether it is pre-mixed mastic, thinset, or special glass tile mortar. Consider whether you are installing mosaic in a dry area such as a kitchen backsplash or a shower and whether the mosaic is translucent. Use Type 1 mastic for a kitchen backsplash with a solid mosaic, Adesilex P10 for translucent glass or natural stone, and thinset for outside applications..
