Anyone used Izonil??

[Bojjit n scarper]

Hi there. I've been asked to price a job which has had an Izonil backing coat used as tanking. The house has been bought at auction so I don't know who has done it or when it was done. All the walls on the ground floor have been knocked off up to 1 metre then covered with Izonil and keyed with a scratching comb.
From what I can tell, this system is designed to be done in one go with the backing coats built up 10mm at a time then a skim coat put on straight after with the same stuff, unless I've got the wrong end of the stick that is!
The suppliers (Travis Perkins) tell me I can use ordinary multi finish on it but I'm sceptical as it's supposed to be a breathable system. It looks too rough to skim straight onto so in an ideal world I would put a thin coat of bonding on before skimming but what products can I use?
Any help is much appreciated!

I looked into using this awhile ago, it's expensive gear so didn't bother using that but as you say it's a breathable backing so yes an gypson product will seal it..

But tbh it's shouldn't matter to much as its only a dpc at ground level so should stop rising damp, if you are concerned then maybe use a skim like limelight finish?

IMO I wouldn't give 2 Fcks they have had the backing done and asked you to skim it so just put in your disclaimers and get it skimmed

Limelite finish is like rocking horse poo!three different travis perkins I rang up and said they had it in stock when I arrived they either didn't have it or it was out of date by over a year,wasted a full day looking for it

Izonil is great stuff, absolutely waterproof at 17mm thick , used it to produce birdbath.

As above, used it a few years back very expensive though.
