Is it ok to pour floor leveling compound over hardibacker cement board?
ive used a liquid leveling compound on it and got great results on cement board though the drying was spotty and needed more than one layer to achieve desired results. it was only on a very small area about 8 x 10
what do the instructions say?
Yes, just make sure you've used a lot of screws to hold the backer board down or your compound will crack to pieces if the board moves at all.
