A couple questions about Ditra uncoupling membrane. First, for you guys with real world experience with this, does Ditra really noticeably work in preventing cracked tiles and grout lines? I know every situation is different, but on the whole, does it work as promoted? And second, they...

Thanks for that. Do most of the tiles, or at least some of them, come with a beveled edge? Is that better than a sharp edge for a novice, assuming you like the look? And since the tiles are the same length, even if you stagger them don't you end up with a repeating pattern? Or are you saying...

Hi, I have set square ceramic floor and shower tiles a few times but have never set large or rectangular tiles. I am thinking of doing about 800 square feet on my concrete slab in the porcelain wood-look planks. I have concerns about getting the floor even without excessive lippage. So here...

Ernesto, is the backer rod and caulk stiff enough to prevent the movement you left with the small gap?

Okay, maybe I am making the question too complicated. I will try one simple question to see if it helps: If glued-down wood on concrete expands one half inch over a long span, what happens to the glue joint?

I understand what you guys are saying, wood expands and contracts. Fine, but let's say you glue down on concrete. The only way for the wood to expand then would be for the glue to let loose. And if you nail down onto a wood subfloor, you are forcing the subfloor and flooring to move together...

So then why leave a large expansion gap? Are you saying it's not necessary? And if it is necessary, then my question remains.

Hardwood, engineered hardwood, laminate, and vinyl plank all require an expansion gap around the perimeter. I can understand this on a floating floor, but they require it even with nail down, or glue down. What I don't get is this: if the board is glued down, then to expand at the end of a...
