Hi all, was wondering about using hardibacker for a custom shower on the walls vs Durock / Wonderboard for the ease in cutting but I haven't used it except on floors and didn't know if the 1/2" hardiboard can be installed directly to the wall studs or is a backer of somesort required. Maybe it is my imagination but it seems like Durock is a bit more rigid and may give a stiffer / stronger wall than Hardibacker. No studs are spaced further than 16"oc. Does anyone have any thoughts. Thanks in advance
Cheers, Steve K

Hi Steve, Welcome aboard. :)

It's a matter of preference. Hardi is really stiff and straight, though. :)

Wonderboard and durock are not the same at all, durock is a little floppy wonderboard is rigid, and utilicrete is also very rigid. I would use one of the two on walls rather than durock.

I am using 1/2 hardibacker in my shower rebuild. Its a lot lighter and easyer to cut.

thanks everyone for the responces - mighty righteous. Hardibacker 500 is what we're using, very good workability I think I might make this the first tile backer choice instead of the other cement boards from here out

Steve Wonderboard Is The Right Way .it's Easy To Work With .yes It's Heavy ,but It Is A Very Solid Base For Tile.we Have Alway Put Blocking At All Seams .fiberglass Tape Joints.if Mud Cap Is To Be Used I Use 1/2 " And 1/4" --5/16.if You Use Wonderboard Us The Cementboard Screws ,its Worth The $'s.try The Difference.phil

For what it's worth, my backerboard of choice for floors is Hardibacker, but walls are a different story. I find Hardibacker to be fine for 4x4's, but for larger tiles, I prefer Durock. I feel like I get a better bond with Durock on my walls, with less slipage. Wonderboard in an excellent product too, but Durock has tapered seams for taping.

Between Hardi and Wonder, Which one cuts easier? Do you score them like drywall and snap? Do you need a tungsten blade, or will a utility knife work?

Hey, I answered my own question. I bought a sheet of each. The Hardi cuts and works much easier. The screw can be screwed in flush with no problems.

I'm a newbie and I am using Hardibacker 500 for my bathroom remodel and like the way it cuts and trims, but have noticed this about using screws: just because the screwhead looks flush, as often as not the thread of the screw in the hardibacker doesn't spin freely in the board, and as a result, the sheet is held about 1/8" away from the studs. I beat it with a block of wood between it and my hammer and then tighten the screws some more. Repeat. The screw package claims no predrilling required, but I think that it would sure help a lot.
