Are there no fixing instructions with the panels . I work with a guy who sometimes puts pva panels and he battens the ceiling and uses hidden nail technique . Have you tanked the ceiling ? If not it doesn't gave any relevance to the question if you have and you intend sticking panels then as above .

Yes the ceiling is tanked as well that's why I would prefer not to nail.the panels are very light,just need a glue that sticks well to the tanking.

Kerdi Fix

that a guess @Waluigi ? Or have you spoken to @Mapei UK Marketing or @Schlüter-Systems Ltd about using that product for this application?

Been on to mapei they said speak to pvc supplier.speak to pvc supplier and they said speak to mapei lol.

I'd imagine if you can get something that bonds to the pvc it would be ok on the mapei.

It’s an educated guess based on knowing what it will stick to in the industry after reading the data sheet before using it on waterproofing jobs, in particular when it’s been used to bond Kerdi sheet to ‘difficult’ substrates. However I’d not actually use Kerdi Fix, I’d find something else that has similar characteristics yet less expensive due to the volume of Kerdi fix required.

In reality I’d not be bonding PVC to a ceiling full stop, I’d mechanically fix them.

if you are going to advise using a product which you don't know will work it would be a good idea to say so @Waluigi .

we wouldn't want someone to take advice which turned out not to work would we

we don't know what education you have had so we know how educated your guess is

Been on to mapei they said speak to pvc supplier.speak to pvc supplier and they said speak to mapei lol.

I know you’re not keen on mechanically fixing the PVC but how about using a small amount of neutral curing silicone at each fixing point as it meets the membrane?

Is there a reason you’ve tanked the ceiling? My apologies if you’ve already explained.

It's going to be a steam room as well waluigi,I'm pretty sure I could get away with it being screwed up.but I would rather not break the seal.

Well there you go - a little bit more information - a steam room!
Gone from a simple shower to specialist installation in 1 sentence.
Wall construction, insulation, moisture breaks, temperature ranges....

All I want too do is stick this on the ceiling that's it. Will only be 1200mm pieces.
