I'm new to installing glass tile. I have a 7 foot pole made up of 4 wood studs that supports a support beam. We've decided to use 1" glass tiles to cover it. Just wondering what kind of base we need for this. Is thinset enough to fill in the cracks made between each stud? This pole is close to the middle of the basement so there is no need for water protection. Is there something we need to make sure the mortar (or thinset) doesn't soak into the stud?
