Great mortar

Good adhesion, and easy enough to get near 100% coverage on large format tile. Very easy to spread. Will purchase again.

Great Thinset

Would Recommend

This is great thinset. It might be a little more expensive than others but it’s well packaged in clean plastic (not covered in dust). We used it to set large format tiles (2x4ft on countertops and 1x2ft on walls as a backsplash). Easy to mix and apply. Recommended.

This thinset worked very well for my tile installation. It was easy to mix and apply, and the white color was a great choice for the tile I was installing. It provided good coverage and helped create a solid, secure installation. The 50-pound bag was also a good size for a larger project. Overall, I was very pleased with the results.
