Thinset
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.[1] It is usually used to attach tile or stone to surfaces such as cement or concrete.[2] The adoption of a thinset mortar based installation method has led to an expansion in the usage of ceramic tiles throughout the latter half of the 20th century.[3] Further, It is particularly popular among mosaicists for outdoor applications.[4]
Thinset is generally available in two types: unmodified and modified (polymer-modified).[5][6] 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.).[3] It is usually more expensive than standard, unmodified thinset.
