Floater

[Stef]

Went & looked at a job for someone I know.
Long story short they had a "Tiler" in to look at it & he recommends a decoupler to take away a very slight bounce in the floor.
They wanted me to tile originally but didn't want to wait 4/6 months for me.
This floor is made up of 22mm caberdeck flooring sitting on top of 50mm king span on top of concrete.
There is very little movement in the floor, I have tiled to worse wooden floors.
I have tiled to floating floors before with success but it's not something I like doing.
Any views on this scenario would be appreciated.

what tiles are they?
possibly overboard with 6mm nmp or hardie then tm s2?

600 polished porcs.
The floor needs levelled also so going to overboard with Hardie or thermal & the extra weight of the leveller will hopefully tighten the floor further.
Adhesive will be TM ultimate, no compromise on that they have been told.

sounds like a good plan to me

Before reading this thread I thought it was going to be about finding one when measuring up a bathroom

take it all out back to concreate, level floor, stick down 50mm insulation board then tile.
a good chance to ask / recommend some ufh, electric or retro fit wet.
don't like the term 'hopefully'

If height allows you could overboard with 10mm Hardiebacker.
It is far more rigid than the 6mm,it's not just a thicker version of the 6mm, it looks/feels like it is made on a separate production line to the 6mm.

It's just all been put in, there's no chance of them ripping it back out.
Hopefully was the best scenario I could come up with for them seeing as it's a floating floor.

It's 12mm, Hardie backer 500.
I've got sheets of it in my garage.
I'm waiting on the floor getting cleared out to see how much the floor needs to come up.

the best i have ever tested on defletion on a floor was the blanke perma matt very pricey but can handle a lot of movement .test the floors movement with a glass of water half fill then mark every 5mm then place on floor in diffrent places walk up and down past it use your phone to record the movement .one of you then two and three in diffrent directions .half the measurement to give you the answer

I put the dewalt laser on the floor & got them to walk round the room & I marked the difference, it was just over 1mm.
There's very little movement in the floor.
Its because it's classed as a floater that's getting to me.

I'm sure @AliGage did one a while back? Put fixings through it to make it more stable

hi stef the big question here for you is whats going on the floor after it is tiled as the the movement is very little
and most decouplers would handle this .have seen these floors fail after kitchen fitted middle breakfast bar loaded with grannit work top. because the concarete floor was not gone over with a self leveler the king span was sitting on the high spots the weight of the breakfast bar with the grannit pushed down the floor leading to cracks in the tiles runing off all four conrners that was 10mm 600x600 porcs

Yep sure did!
Here u go @Stef

I have tiled a floater of the same nature last year, I over boarded with nmp and tiled it as normal with tile master rapid flexi. Was fine.

Hi Ray, this is the exact worry on this floor, kitchen is tall units both end then there's a big island in the middle with cooker, sink etc.
I'm not sure about worktop yet as we haven't got to that stage, will find out tomorrow.
I'm trying to give them a ball park figure so they know what they are looking at.
