I've seen that particular video before. Isn't that "treated plywood" he is getting ready to install tile on? And his recommendation to use Varathane to seal the plywood first? This guy has never heard of any of the rule books that pertain to ceramic tile installation.
Just for those that don't know any better and get a look at this guys videos, what he is suggesting IS NOT approved by the Tile Council of North America as far as I know.
Tim Carter needs to attend a few tile installation classes and check his "video making ego" at the door when he arrives.
