Hi Henry,I received all the samples I had recently order, we love the Iridescent recycled glass tile in turquoise. I have had several conversations with you about proper frost proof tile for an Ohio cement pool. Is this tile one that you would recommend....Also, I am a bit confused about how this tile is applied with the plastic on the back? Even holding grudges in the water to look at it falls off.Thanks.Cam Salsberry View answer
