I finished my rough in and pan install for my basement shower. The plan was to use HardiBacker and some form of membrane to seal it. I read that Hardi is a pain in the ass to apply anything to because of how absorbent it is, so I am thinking of taking those down and going a different route. I have a few options and I would really like the opinions of some professionals on this one. Cost is not restrictive, I want to do this right the first time.
Confusing things:
Hardi calls for modified thinset
Kerdi calls for unmodified thinset
AquaDefense calls for a mortar with polymer
Will the unmodified stick well to the Hardi, what about porcelain tiles and glass mosaics? Old school thought is to use modified for those.
My options:
Kerdi over wet Hardi
AquaDefense / Redguard over Hardi (with a primer coat)
Replace Hardi with Kerdi board
My concerns are that I am a long shower taker and wall leaner. I want the wall to be strong and not flex and crack. The studs are on 12in centers. It is very possible that I am being paranoid and all of those methods will last a long time, but I don't do this for a living and I want to do something that will last a long time with minimal maintenance.
My current thought is to tape and mud the joints on the Hardi with good modified thinset. Then put on a prime coat of the roll-on (primer G or diluted redguard), then a full coat and then tile with UltraFlex 2 or equivalent.
I'm gonna go have a beer, because this is confusing as hell!!!!
Thank You
