There are four basic types of grout for ceramic tile: unsanded, fine sanded, quarry type, and epoxy

• Unsanded grout for ceramic tile: This is used for wall/floors tiles where the grout joint is less than 1/8” wide.
• Finely sanded grout for ceramic tile: This is used for floor tiles where the joints are 1/8” to 3/8” wide.
• Quarry-type grout for ceramic tile: This is the same as finely sanded grout for ceramic tiles except that a coarser grade of sand is used. The quarry-type grout for ceramic tile is used for joints that are 3/8” wide to 1/2” wide such as those used with Saltillo tiles.
• Epoxy grout for ceramic tile: This consists of an epoxy resin and hardener. Epoxy grout for ceramic tile is highly resistant to stains and chemicals and has a tremendous bonding strength. It is ideal for countertops and other areas susceptible to stains
