These basic latex products are still quite popular and are readily available, but a new generation of polymer thinsets and grouts is simplifying the installation of latex grout. It is important for installers to understand the differences between regular and enhanced mortars.
Regular thinset mortars and grouts are mixtures of dry sand and cement. Water is added to make a smooth adhesive paste. The chemical process that turns the powders and water into hardened mortar requires that a certain amount of water be present in the material being cured. No water means no curing, thus the requirement for keeping the material moist by damp curing.
