There are various types of thinset mortars formulated to fit specific application needs
or installation requirements. They are categorized as modified and un-modified
thinset. A modified thinset mortar contains polymers formulated into the dry
powder mix that increase the performance and bond strength. This product is
mixed with water. An un-modified mortar is simply a thinset mortar that does not
contain polymer in the dry powder mix. Liquid polymer additives are available for
un-modified thinset 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.
In addition, most manufacturers have created specialized mortars for specific
applications:
• Large Format Tile Mortars (Medium Bed Mortars):
o Formulated for tile with a single edge of 15” or longer.
o Medium bed mortars do not dry as fast as a typical thinset mortar and they
are formulated to significantly reduce the risk of shrinkage in the mortar bed
during the curing process.
• Glass Tile Mortars:
o Formulated to work specifically with glass tiles and mosaics
• Fast Drying Mortars:
o Designed for a faster cure rate to increase installation productivity.
o Allows the grouting process to begin faster than typical mortars.
