When selecting a grout, it's essential to choose the right type for your mosaic tile installation. There are various types of grout available, including cement-based, epoxy-based, and acrylic-based grouts. Each type has its own unique characteristics, advantages, and disadvantages.

Cement-based grouts are the most common type and are suitable for most mosaic tile installations. They're relatively inexpensive and easy to work with, but may require additional sealing to protect them from stains and moisture.
