is there any place i could get any advice on if it needs eml over it ? or some kind of bonding slurry ?

Some of the EWI system suppliers specify thin coat renders onto Polystyrene...... however, they usually specify or supply the polystyrene as part of a complete system.......

What is the application?

yes polymer - modified !
are there any BS standards ?

should it not be keyed ? as it looks very smooth to me !

Insulated System Warm Wall Energy : Knauf Marmorit

OK - I would point this one out - it is another Knauf Business (declaring an interest.... lol). You will find a page with cont6act names and details on this site as well.

Get in touch with someone like Parex as well - their Maite Basecoat is also very good and will probably be suitable!

To be honest, most of the EWI system suppliers will offer a solution onto Polystrene.....

Not sure what BS standards your after - search the BBA Certs for EWI systems, loads of them...... they will have all the relevant BS and EN standards for these sorts of systems........ bear in mind that in BBA approved systems, the Polystyrene comes as part of the system...

You aint got a clue pal, im all for giving advice out, but your taking the piss on this one.

Pick an EWI BBA cert, any of them ....... they reference BS and EN norms for substraights and the render products........

If you want a warranty, talk to one of the system suppliers and get them to confirm their products to your Poly.....
