Travertine tilling help!

[js1454]

I am new to this forum, and i would really appreciate some advice. We are re-fitting our bathroom and have brought travertine tiles for the floors and walls over the bath. I have calculated that the tiles are about 28kg/m2 (600x400).The walls that the travertine will be going onto have just been plastered over render and brick (i now know that plastered walls will only take limit of 20kg/m2). i am quite reluctant to remove the plaster, would i be able to place hardibacker onto the plastered wall fixing with screws into the brick wall and dabs of adhesive?

Just to add , you cannot dot and dab the hardi, serrate the wall and bed the boards on... this PDF will help you out.

All there in the pdf ... for hardibacker 250 (6mm) , if you batten then it has to be hardibacker 500.

Ah! Maybe I heard it about the 500, and thought it was both.. Cheers
