When installing glass tile, a big part of the installation is grouting it after the tile is in place. Many people are not sure as to which type of grout that they should use for this process. Here are a few things to consider about using grout with glass tile.
The first thing that you should look at is the manufacturer recommendation. Each glass tile manufacturer may have their own opinion on what is best to use with their tile. In order to keep your warranties in tact, you should first see what they say.
Mosaic Glass Tile
One of the most popular forms of glass tile is mosaic glass tile. With this type, unsanded grout is usually going to be the best option. Unsanded grout fits better into tiny grout joints like you will find with glass mosaics. This will provide you with an easy installation and the grout will stay in the joints over the long term better.
If you are installing larger field tiles that are made of glass, then sanded grout may be your better option. Since the grout joints are going to be wider, having sand in the grout makes it more sturdy.
