Long time listener, first time caller.
I have seen this both ways: Do you recommend sealing the seams between the 1/8 gap in the subfloor with caulk, or does this prevent the expansion/contraction of the wood? If caulk is used, what kind of caulk do you recommend?
Also, if someone can reassure me that a 3/4 OSB + 1/8 Ditra is enough to support tile, I would like to hear it. It seems so thin compared to the old plywood+Hardibacker.
Thanks!
