Review: Best I’ve ever used - This is for Ardex 77. I am using it on my sub floor under duraroc. It is a fabulous product. I have used many types of mortar and by far this is my favorite. Laticrete was my favorite, this is now my favorite by far. I can lay 4 pieces down before it the bucket starts to get thicker, I’m kinda slow.. lol. It’s spreads like butter and sets in about 24 hours. You won’t be disappointed. ## Features - Cutting-Edge Technology: Ardex X77 MICROTEC Fiber Reinforced Gray Mortar with MICROTEC technology for large format tile installations. - Versatile Applications: Ideal for high traffic areas, building facades, in-floor heating, and swimming pools, ensuring water and frost resistance. - Superior Performance: Extended open time of up to 60 minutes, double the ISO standard, unmatched sag resistance, and outstanding coverage of 110 sq. ft. per bag with a 1/4" sq. notch trowel. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077G9GT8Z | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #694,240 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #650 in Tile Grout | | Color | Gray | | Customer Reviews | 5.0 5.0 out of 5 stars (6) | | Date First Available | November 14, 2017 | | Is Discontinued By Manufacturer | No | | Item Weight | 40 pounds | | Manufacturer | Ardex | | Material | Ceramic, Glass, Porcelain, Stone | | Style | Compact | ## Images ![Ardex X77 Gray Microtec Fiber Reinforced Tile and Stone Mortar 40 lb Bag - Image 1](https://m.media-amazon.com/images/I/51OwZMczd2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best I’ve ever used *by A***I on July 28, 2024* This is for Ardex 77.
