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.Click to see full answer. Similarly, it is asked, is latex modified thinset the same as polymer modified thinset?Mostly a difference in terminology. All thinsets that are latex or polymer modified with have add’l flex and shock resistance ; more so than the basic thinsets. In your case, any of the latex modified or polymer modified thinsets will work.Likewise, what is modified thinset mortar? In many mortar bed installations, the mortar bed will be allowed to cure and then polymer-modified thinset will be used to bond the tile. 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. Furthermore, is latex modified thinset waterproof? All portland based cementious products will allow water to pass through. The latex modified is more resistant due to the latex that is mixed in with the adhesive but that doesn;t make it “waterproof”. The latex also allows a bit more flex in the tile and substrate. As Jason described, thinset itself isn’t waterproof.Will unmodified thinset stick to modified thinset?WarmlyYours Radiant Heating recommends modified thinset mortar for nearly all tile and stone installations. However, if you’re using a Prodeso Installation Membrane, you’ll want to go “old school” and stick with unmodified thinset.
