We all live and learn. Plywood was and still is in some circumstances a suitable substrate for tile although I haven't tiled to plywood in several years. "They" used to say that "water-proof" sheetrock was a suitable substrate in a shower some years ago. Who does that now? I also used to think 8" tiles were big. Well after installing 4" tiles, 8" tiles are twice as big.

I demo'd a tile over ply floor 3 weeks ago and all the tiles were bonded so well that the ply gave before the bond. It was two layers of 1/4" underlayment one nailed, one stapled, over 3/4">>> a genuine cast iron bitch even with my Bosch hammer.

The upstairs bath floor I did last year was similar construct- one layer underlayment nailed over the 3/4" practically self demo'd- 30 minutes with a floor chisel and a 16 oz hammer. I guess his helper did that one

What makes this circumstance differ than most is how his alknowing "Holmesness" is trash talking every trade that came in before.When youre puttin it out there like he does you should not only meet but exceed standards.It seems to me he does this for the most part.I wasnt even aware he tiled over plywood.Well shoot,he could also have you mastic for some of his flooring installs.Isnt that also approved under certain conditions?

But naw,Im down wit Holmes!He's alright for the most part.He might could lay off the tanning bed a lil!Ill tell you what he's a lot better than Bath Crashers/Bathtastics Matt Muenster....now thaaat guy....Im gonna shut up now

Tiling direct to ply is becoming one of my favorite methods. I use Halex.

Amen to that!! Do my eyes deceive me, or am I not the only one no more?

For those who think tiling directly to plywood isn't an "approved" method, Check F-149

There is absolutely nothing wrong with tiling over plywood floors. As long as there is a 3/4" subfloor and then a 1/2 " exterior plywood underlay screwed every 2" on the seams and 6x6 screws in the field. Detra is an anti fracture membrane. Designed when the substrate can fracture. Like a concrete slab. I have never seen a wood floor fracture if it has been correctly installed and prepped. I have seen concrete floors crack and fracture due to ground movement ( slab on grade) and these floors were correctly installed ( or poured) with the correct ground compaction, rebar size and placement along with a high MPA. I say take the time and prep the plywood properly and save using Detra for when you have potential ground moving issues like frost under concrete slabs.

From the Schluter website:

Quote:
Designed specifically for ceramic tile and dimension stone installations, Schluter-DITRA serves as an uncoupling layer, waterproofing membrane, and vapor management layer that accommodates moisture from beneath the tile covering. Further, DITRA performs all these functions while still providing adequate support/load distribution for the tile covering.
Don't see anything there about anti-fracture. Not saying it wouldn't work that way, but Schluter apparently refrains from touting it as such.

OK lets say with the right thin set and methods of application it is in most cases successful what I am harping on this thread is not the over the ply install it is the plain and simple tile job the installer was doing.
If you have not seen the show, you won't understand.
I'm gonna see if I can dig a link.

The title is TILES & TIBULATIONS
I can't find the link I GTG, another plywood condo sub floor today.

Thank you Brian. I'll move to the back of the class and stick my tile to waterproof sheetrock with bucket mastic.

Holmes on Homes needs choked

Just watched him do a basement remodel.. He siliconed 1" sheets of foam to the concrete floor, then plywood, then ditra. WTF? Told the H/O's that was the proper way to insure the tile wont crack...

How about just putting the ditra over the concrete you HACK..
