Thanks! The reason I am asking is, I have had a mosaic planned for a long time to place outside in front of my 500 gal propane tank as a partial screen. I had never started it, and then, my shower door fell off. The door is still good, but can;t be rehung. I wanted to find a use for it that didn;t include chucking it into the landfill. Will those glues work for an outdoor piece? which would be best?
