I have also been using 1/4 inch and 1/2 inch hardibacker for outdoor
tiled panels. It was recommended to me by an experienced tilesetter and
it seems to work well and hold up. The panel itself is usually set into
a wall so no moisture enters from the back or the sides. I use speedset
(thinset) for an adhesive and thus coat the hardy backer quite
thoroughly with the speedset. The speedset has an epoxy component. I
would think with that as well as sealed grout and tile , moisture would
not penetrate. I have also seen the Hardibacker weather well when stored
outside. This is a mild climate, yet I am impressed with the
Hardibacker. For me, it outperforms Wonderboard and wood for this type
of application.Of course, it is hard to argue with the label!
