Tub surround?

[Shelbie]

I am getting ready to tile my bathtub surround. When I tore out the old tub I put Hardie backerboard directly to the framing studs with no vapor barrier. I assume I need to use some kind of waterproof membrane over the Hardie board? What is the suggested product to use?

Thanks

CAn you not remove hardi and still install the vapour membrane.. where in the US are you.?

[Shelbie]

I guess I could, it's just that everything is so square and pretty right now I hate to take the board down. I would never get it back up as neat and clean as it is now.

I'm in Micky Mouse's back yard, Orlando Florida. How did you know I was in the US?

Yeah I figured it was some terminology I used. You know Y'all talk funny too. When I raise the hood of my car you raise the bonnet.

If you use a tanking solution then no vapour from ingression will effect the cavity of the wall..
