I just constructed an island made of 3 laminated sheets of 3/4" ply. I am wrapping 16" granite tile 3/8" thick on the sides down to the floor and the top.
Do I need medium bed mortar for the sides AND top, or just the vertical sides? Due to thickness constraints the sides have Ditra, the top has CBU. It's complicated ( the reason for the thickness constraints )
I would prefer to use thinset all around but I dont think it will hold up to well on the vert surfaces. Should be ok on the horizontal top of the island - no foot traffic obviously.
Any thoughts ?
Help is totally appreciated !
