OmniGrip Thinset - help?!?
We're installing 700 sq ft of 13x13 porcelain tile flooring over 1/4" thick Hardibacker in our kitchen and foyer. We're about half way done - 300 sq ft - and noticing that the OmniGrip thinset we bought from Home Depot seems to have some movement, even in tile that's be "drying" for over a week. The movement is minimal, but you notice it when you step on the corners. So, I went online and heard a lot of gripes about this OmniGrip. Now I'm not sure if we should keep going and start grouting given the thinset material we've used. What do you think regarding how much tile movement is acceptable? I'm really worried that this is going to give us problems down the road.
