There are various types of thin-set mortars formulated to
fit specific application needs or requirements. They are
categorized as modified and un-modified. A modified
thin-set mortar contains polymers formulated into the
dry mix that increase its performance and strength. An
un-modified mortar is simply a thin-set mortar that does not
contain polymer in the dry mix. Liquid polymer additives are
available for un-modified thin-set mortars to boost bond
strengths, water resistance or flexibility. These liquid additives
are used in place of water and should never be diluted,
unless otherwise noted on the product directions.
