Fibre slc thickness on wet ufh

[Midlandceramics]

Is this like brio board ! Have considerd a over board but it's getting a solid fixing down through the 25 mm heating board underneath to the concreate , have used a lot of quality primers ! And prima star and Eco prima grip stick like hell to metal inc steel and alli ! And also ardex do 'one p4 or p5

Ha ha !! Yeh they told me to put 10mm ply ! Unbelievable

Just lay it on top and glue the joints (with their glue). It's a floating floor but not like the chipboard ones! It's blooming heavy. And completely stable.

Yeh brio board still got the fixing it down prob !! I think that's 26 mm aswell !! Too thick ! With the heating board and trav/ady I'm at 45 mm and I've got nothing in between yet !! Lol ! Hope they don't want to use the front door !!

Laying a 12mm trav 600x300 on a floating floor , don't sound right to me ! And would still have to use ditra with it .as all stone with ufh has got to have a crack Matt really

What is the sub floor? If its timber ( joists) might be worth taking the floor boards up and installing ufh between the joists.? Would save 25mm

so will the vertical deflection negate the lateral deflection??? more crap that 18 year old PST's with an A level in sales come out with :incazzato:

Honestly you can tile with no anti fracture mat as the floor does not expand and contract with the underfloor. It is completely stable. Ring the tech line to confirm.

think he said was concrete chalker..... what sort of ufh system is this called mate want to look into it. cheers

 

[Midlandceramics]

Concrete mate !!!! Well ! This is a fairly new system a retro-fit , over floor fitted system designed to go over your existing sub floor .its a comp board with alliminum outer with poly pipe in a grove I've got to ignore the manafactures spec on laying over this and try and treat it like a any ufh instalation. The company hasn't got a clue on tiling on top of this ! I've come to the conclusion of fixing the boards down with mega strength and screwed to concrete then prima grip bond it ! With a fibre slc and ditra mat on top !! But Carnt really find out what depth the slc should be on this application. Just to make this job even more probmatic ! I've got 44m2 of trav on top ! But it is premium ! Wouldn't use any thing else

Where is the vertical deflection coming from.?

Ok thanks

You will find very little cement based addys will stick too a foil backing.....

Second pic now loaded but pointless as its a concrete floor.

Tilemaster do one ! But I would use prima grip first !! Used it on steel steps before
