Thinset (also called thinset mortar, thinset cement, dryset mortar, or drybond mortar) is an adhesive mortar made of cement, fine sand and a water-retaining agent such as an alkyl derivative of cellulose. It is usually used to attach tile or stone to surfaces such as cement or concrete. It is particularly popular among mosaicists for outdoor applications
Thinset is generally available in two types: unmodified and modified (polymer-modified). Modified thinset has been developed to enhance the strength of the bond in addition to improving working conditions of the material (i.e. working time, working temperature range, etc.). It is usually more expensive than standard, unmodified thinset.
