Easy to use and best coverage

Would Recommend

I used MAPEI Ultralite Pro for my large-format tile installation and was very impressed. It is lightweight, easy to mix, and spreads smoothly with excellent coverage. The tiles stayed in place without sagging, even on walls. It also gave strong adhesion and enough working time to adjust tiles properly. Overall, a high-quality thin-set mortar that makes professional-looking tile installation much easier.

Best all around choice

Would Recommend

I've been using this product for decades. I will drive extra miles to purchase it. It mixes to a smooth sticky consistency and holds big and small tiles alike. So glad Lowes is carrying it now. The pot life is long and it doesn't get thicker while you're working. My go to for floors and walls. Highly recommend it.

The right mortar for the size of your floor tiles.

This is a great product. A little pricy. But you and your contractors will love it. Make sure to get the right mortar for the size of your tile. Because of my budget I did have to drop down to "another type" of mortar to finish up a large room. My contractors did mention to me that they missed using the MAPEI, because of how easy it was to use.
