6mm ply another fail on the way.

6mm ply?!

dude, it would then be 6mm ply screwed at 100mm squared intervals on to 25mm ply... thats more than good enough. 9mm would raise the floor too much as there is already a bad step in to the room. if i cant get a perfect lift on the old floor and it is uneven, then i will have to consider lifting the 25mm ply as well and replacing with 18mm caber flooring glued and screwed with 9mm screwed on top of that.

6mm ply?!

6mm on a perfectly flat solid newly constructed floor is fine.. agreed not good enough for anything else.... christ almighty.... clint eastwood once said.... opinions are like assholes.... everybody has one.

There are far better products these days than ply. Why not use a proper tile backer board?

 

[AndY mac]

Just my opinion I always avoid tiling on ply at any chance ( live surface ) backer board or membrane all the time.

It's like comparing pigeons and mobile phones, one might do the job the other will definitely do it

i have only ever used plywood and never had any issues at all... easy to cut.. bastard to screw down, has to be primed, but does the job. I always thought backer was too expensive.

Like your logic lee Mac.

 

[nick giles]

would a bal membrane glued over the whole floor stop the sideways movement, because that is the main issue, but ply would also help with any vertical movement.

Why ignore advancements in technology, ply might be a bit cheaper, but how much does a failure cost?

 

[nick giles]

Like your logic lee Mac.

im being double macced

 

[nick giles]

it wouldnt have failed with an overboarding regardless of the nature of the overboarding. the one and only mistake was no overboarding

 

[AndY mac]

Backer board very reasonable compared to a fail. In the olden days I'd had a few fails on ply either de laminating or just throwing a tile for no reason live surface. No fails on any of the dead surfaces.

Return of the macs. Dude.

try not to tile to ply but definitely don't tile to 6mm ply.
Ply is not the same as we got years ago, it's cheap crap now & has been for a while.
Overboard with thermal or Hardie or use a decoupler.
