I recently sought tile advice at Johnbridge.com and was encouraged to consider deck mud instead of Durock or other CBU's. Anyone pour deck mud? How did it turn out? I did a search for deck mud but didn't get much.
I'm just about to install my hearth using one layer of 1/2" Micore board sandwiched between two layers of Durock. This should give me an R value of about 1.9. If I went with deck mud, since concrete doesn't have much R value, how might I achieve a comparable R value?
