Apologies for duplicating a question in my other thread but thought it was getting a bit long ... so quick qu' if I may please?

Is there an alternative to the suggested 18mm WBP?
(Height tolerance restriction!)

If we could get away with an alternative overlay product say of max 6mm on top of chipboard flooring sheets what would you recommend? and how would you use it with large format porcelain tiles

Many thanks again all

Hardibacker 6mm for me. After removing the pva by sanding the chipboard down.

Make sure chipboard is screwed (not nailed) and then put down a thin layer of weber rapid plus and ad250 to the chipboard and then put hardi on top. Screw Hardi down and then use weber rapid plus and ad250 to stick tiles to hardi.

Just out of interest what size of tiles are they?

600 x 300mm (6mm depth)

can you recommend best price suppliers? need to keep further costs down.

If the chipboard floor has minimal deflection/bounce.. then you can overboard with hardibacker 250 6mm.. and no matter whether it is pva'd it will be fine as the adhesive is to fill voids and you screw it down....but the floor must be solid.

And you need to use an S2 adhesive still IMO..

Either a 2 part elastomeric adhesive or for hubbs to work slow.. Mapei Kera flex maxi..

Hubby wants no part - is still prepared just to tile straight onto chipboard after PVA'ing and use the ready mix Unibond adhesive he's bought - thinks I'm 'internet interfering' and everything will be fine - wasn't happy when I questioned builder's use of chipboard in first place... has thrown the literal trowel at me to sort out!

So its me and mum with a whole load of help from you guys

No probs.. we will speak english from now on.,.

Maybe tell hubby we do this professionally and we like it to last.

But then if he wants to go ahead and it not last he can always rely on you to say 'i told you so'

thanks all
looks like I've got my shopping list for tomorrow... think I'll buy online
please feel free to impart any further knowledge or tips that you think may help me or at least pray for me

I am praying..

Goodnight all... I may be back if things don't go to plan!

Goodnight..
