Which Grout for Floor Tiles?

Sanded grout should be your default choice for general use tiling, such as for flooring and walls. Sanded grout is widely available, has the greatest range of mixed color choices, and reduces grout shrinkage.

Do you need special grout for floor tiles?

Well, the short answer would be a simple no – you should not attempt to install tile without grout. Why's that, you might wonder. It's not like grout adds to the stability of the tile installation (unless we talk about a few exceptional cases) so why is grout necessary?

Can I use unsanded grout on a floor?

For example, unsanded grout is recommended for highly polished, easily scratched tiles such as marble because the aggregate in sanded grouts may damage these types of tiles. Unsanded grout should not be used in floor tile, however, because the grout can crack and break under the pressure of floor traffic.
