Greetings All,
I plan on using Hardiboard as a backer for bathroom tile and it will sit
on 3/4 plywood. What is used to bond the Hardiboard to the ply? Also, the
Hardiboard doesn't have tapered edges like Durock does, is it ok to tape
and mud the joints where the Hardiboard meets?
Lastly, our basement is a little damp and I'd like to know if a regular
dehumidifier is best or if something else is better.
Thanks, Mark

I agree with Dado and Frank about the taping.

The hardiebacker has concave areas (dimples) where the nails or screws are
to be placed. That is a lot of nails if you are doing it by hand. Last time
I did half of a 12x18 room I was worn out from pounding. Most of the pros
around here just use 2" galvanized RS nails fired from a paslode or air
nailer.

Don't know a thing about the humidifier but the advice you have gotten
sounds right.
