## Questions & Answers

**Q: What color is this**
A: White

**Q: I saw the instruction say to mix for 2-3 minutes, then I can use it right away. Is there no slake time?**
A: The instructions do not specify any slack time being required. Only "just prior to application on the substrate, the mixture should be stirred again to ensure a cream, smooth lump-free consistency". So if it sits awhile be sure to stir it up again. It really holds very well. I used it on vertical and overhead surfaces.

**Q: Is this good to mud backer board joints and tape pre-tile?**
A: Ardex X&& is the ideal mortar for large porcelain tile installations in the most demanding environments. It is smooth, creamy and easy to trowel ploy-modified mortar formulated with Microtec technology with outstanding strength, flexibility and sag resistance.

**Q: How much coverage in a bag?**
A: Coverage: 1/4”  x  1/4”  (6  mm) sq. notch  trowel 110  ft²  (10.2m²)  per  bag 

 1/4”  x  3/8”  (6  mm  x 9 mm) sq.  notch trowel  = 82.5  ft²  (7.6  m²)  per  bag 

1/2”  x  1/2”  (12  mm)  sq.  notch  trowel  = 55  ft²  (5.1  m²)  per  bag 

Coverage  varies  with  texture  of  substrate  surface.

### ⭐⭐⭐⭐⭐ holds tile well when installing on a wall
*by J***R on February 23, 2021*

Ardex does a great job holding tile to the wall allowing the installer time to level and adjust tiles without fighting to hold them in place on a vertical surface.

### ⭐⭐ Falls from ceiling
*by A***R on November 3, 2024*

Can’t even handle 12x24 tiles on the ceiling. I back butter my tiles. I broke 3 tiles because of this expensive stuff. The schluter all set held fine and it’s not even a large format thin set. I might try pro lite instead.
