My husband was leery, to say the least, so he made plywood backs for me to work on instead of putting it directly on the wall. That was fine with me because I had enough work to do at the house (tiling, painting, countertops, etc) this I was able to work on in front of the T.V. and get a break from the craziness of building the house.
By this time I'd done plenty of tile-work so I tried applying the rocks like tile, with mortar. Yeah, that didn't work. When he went to attach my finished boards to the wall they just fell right off. I was determined to have this backsplash so I started again. This time I used construction glue and a caulk gun. Worked like a charm.
You need to be careful around outlets and choose fairly flat rocks, I still have some gapping here and there but it's workable.
