Which grout is used for a more flexible and less permeable finish than cement grout?

Explanation:
Latex grout is cement grout that has latex polymer additives. The polymers make the grout more elastic, so it can bend a little with tile movement without cracking. They also fill micro-pores, reducing water absorption and making the finish less permeable than plain cement grout. This combination—more flexibility and lower permeability—explains why latex grout best fits the description. Epoxy grout is highly impermeable but tends to be more rigid, standard cement grout is more porous, and drywall grout isn’t used for tile installations.
