What Is Polymer Modified Thinset Mortar

Modified thinset, also known as latex or polymer modified thinset, is a mix of Portland cement, sand, and latex/polymer additives. Modified thinsets are suitable for a variety of tiles and surfaces, and have excellent adhesion and bond strength. They reduce water absorption, as well as resist shock and impact.

What is the difference between Thinset and modified thinset?

Unmodified thinset has been around forever. … Unlike unmodified mortar, which consists only of a blend of Portland cement, sand, and water retention agents, modified thinset includes additional retention products, such as latex polymers, which can increase its performance and strength.

Is polymer modified mortar the same as latex modified mortar?

What is latex-modified thinset? Thinset cement, to which polymers have been added, is commonly called latex-Portland cement mortar. In fact, this term is a bit of a misnomer. The original polymers used to modify thinset were based on latex and the term originates from their use.
