Custom Mosaic on Hardi Backer Board

I just accepted a commission for a stained glass mosaic that will hang on the outside of a house. I have done many outdoor mosaics on wood in protected areas but this will be fully expose to the elements so I plan on using Hardi Backer board as my substrate but don't know how to #1 cut it or #2 when it is finished how to hang it.
Client is waffling on permanent installation or removable in case of hurricane/ nor'easter, I cannot begin mosaic really without knowing.. I also will need to make it more rigid, can't have flex on a mosaic :) can I use construction adhesive to sandwich two pieces together ? Thanks.

Got a question about this project?

    Than you Deb, check out my Glassy Lass Mosaics page on face book for more.
    I use a glue called Weldbond. But, since this was posted I no longer use wood as a substrate for outdoors. Freeze and thaw and moisture all eventually effect it.
    I use a foam
