I want to brag. I've just finished installing a tempered mosaic glass tile back board behind and next to the stove. I was worried that this type of tile would not take the bouncing about from traveling. I found a neat product that is a self-stick rubberized material (I do not know the brand name) that I mounted to the walls. It will accept a lot of movement. I then used a product called Bondera which is a web type of mastic that comes in a roll. It is reinforced with a fiber web. One peels off the back non-stick layer, presses it against the rubberized material, then removes the front non-stick layer and presses the title into the mastic. Grout can be applied immediately. Only problem was - I had to learn to keep my mouth shut when I cut the glass tile. I used a wet saw and it threw stuff all over. Safety glasses are a must.
I'll let all know if this works after we get to Needles, CA in Nov.
