I have a balcony that I want to tile. The floor is covered with this rubber material that is glued onto a plastic sheet of some sort, probably some kind of insulating material, and I think there is foam underneath that.
I am not sure what the material is. Can I put plywood on top of that? Is there an adhesive strong enough to fix the plywood and make it solid?
I wish I knew what the material was. Please help me!
