After putting the hardiback it was suggested by the manufacturer to use self leveler to help with the problem of high and low areas. Is this easy to use or are we better off trying to put thicker thinset in areas that are low? We are off by 1/2" in some areas. Thanks for all the help.
Tape is necessary and god forbid you have a problem in the future the warranty wont be void because you didnt use it.
As far as self lveling areas:
No its not hard at all. Just remember to wipe the hardie backer SPOTLESS of dust and wipe it with a damp sponge just before using the leveler.
As far as floating the tile as you go:
I wouldnt suggest it unless youve done it before. I would suggest using the leveler and getting it as close as possible. You can take care of the rest as you tile it.
