Sorry but tiling direct to chipboard is not right.. no matter what the tile shop told you.. the tile adhesive might well stick to it but the chipboard will not hold the tiles..

Oh no. What do I do Dave ?

 

[kilty55]

you dont need the mats for the concrete floors imo

as above as well dont tile direct to chipboard kev,go with the cement boards as planned

 

[kevg]

ok, so the concrete floor is fine..

If I lay something like no more ply on top of the chipboard, would that be ok then ? So my layers would be..

Chipboard
No more ply (screwed)
Adhesive
Tile

I wouldnt have to put an adhesive layer between the chipboard and the no more ply ?

if the chipboard is solid i would overboard with cement boards (hardi or similar) lay them with the adhesive and screwed 200mm centres. the jasmine grout dirties easy so if you're adamant on using it make sure you seal it. i've recently done a full bathroom in marble grouted with limestone and looked awesome. good luck

What I find is there is not a correct way that everyone adhere's to. Tile Giant tells me its fine to tile directly to the chipboard, Mapei says its fine to tile directly to chipboard as long as Latex Plus is used. Various people use backerboard then tile and others use backerboard and a membrane then tile.

I'm finding it increasingly difficult to find a method that will work for me and one that doesnt involve multiple layers upon layers of adhesive, backerboard and tile that will have my transition from one room to the other the size of a pavement step.

hiya kev i understand your getting frustrated

please do not tile to the chipboard just remove the thought right out your mind as imo it will end in tears
you dont need a membrane for your concrete floors, and i would just use a backerboard on the chipboard floors as long as they are solid

i use these methods in most installations you have described and never had an issue i hope this helps

Mapei say the adhesive can be used on chipboard.. i do not dispute that.. what i am saying is that the chipboard isn't a suitable substrate to tile directly too ..

It is time retailers and adhesive comps recognise this as well.. after all bs5385 does..??

Thanks Dave, I completely agree.

Would I get away with laying 6mm no more ply glued down to the chipboard and screwed ? Then tile directly onto that ?

As long as it is deflection free then yep.. no probs..

Done ! Will order that up tomorrow.

Thanks again. Don't know what I would do without this forum.

Kev did you get white adhesive for the marble?

Hey Scottley, yeah I did. White all round, Keraquick (white) and Pro Flex (White)

 

[Scott]

Not sure about the proflex for the marble though? Need one of the others to clarify whether the setting time will affect the marble due to the absorbtion of the moisture. Proflex has a longer pot life than rapid set

The pro flex is for the concrete floor in which I'm laying porcelain tiles. Please don't tell me I've been wrongly advised by the shop and this is not suitable too ? This is turning into a nightmare.

It is fine..
