Add Years to Your New Flooring with Polymer Modified Thinset Mortars

As a tile installation technician, you already know the purpose of thinset. In the simplest terms, it’s the glue that sticks all the tile together and in place.

However, thinset isn’t one size fits all. Some thinsets are modified while others are unmodified. So, what’s the difference?

Unmodified thinset, also known as dry-set mortar, is made up of Portland cement mixed with sand and additives that impact the retention of water. Unmodified thinset is used in thin-bed installations using ceramic or natural stone tiles over many types of surfaces.

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.

Which should you use? As a general rule, glass and porcelain tile typically require modified thinset, while more traditional tiles can be installed with either. However, it’s important to follow the tile manufacturer’s recommendations, as the tile you’re installing may have special qualities and require a specific thinset.

If your tile manufacturer calls for polymer modified thinset, we carry a number of options at Tile Pro Depot. Here are just a couple:


Laticrete 255 MULTIMAX Multipurpose Thinset Mortar

255 MULTIMAX is a patented polymer modified multipurpose thinset mortar. It is reinforced with Kevlar technology for a fantastic non-sag performance and allows for adjustability of large format tile and stone on walls. Simply mix with water for maximum strength and performance.

This multipurpose thinset can be built up to ¾” without shrinkage on floors. It also won’t have slump, sag, or lippage. The consistency is incredibly lightweight, which allows for ease of troweling onto the substrate. A 40 pound bag of 255 MULTIMAX provides the same amount of coverage as a 50 pound bag of standard thinset – allowing you to maximize your money! Select the Best Trowel Size
