Tiling an outside wall

[BazzaS]

She who must be obeyed has decreed that one of our outside wall panels (currently cement rendered & sound) should be tiled with broken tile pieces to create a random mosaic.
Can anyone advise whether there's any special adhesive and grout needed for this enterprise ?
Has anyone out there ever embarked on such an adventure and do you have any tips (not doing it is not an option !).

Thanks

Something that can come out pretty effective, is creating the slab seperately, and then fixing into place in one piece. Do you have some dimentions, and how much depth do you have to play with?

I would suggest that you go for a powdered adhesive that is frost proof and waterproof, look for one suitable for swimming pools buy makers such as BAL and Ardex.
