Drywall on waterproof paint

Hi,

Looking at putting drywall adhesive onto a bricked wall which has been DPC injected and coated with 3 layers of waterproofing paint. The last coat of paint wasn’t blinded with sand.
Does anyone have any advice on how to get the drywall adhesive to stick to the waterproof paint so it can be boarded? Framing out could also be an option

Thanks
 
Sand over for a a key and blue grit a bit and will be OK. Foam will stick best however a angle grinder and break surface a bit will definitely help and easy to do with 80g flap wheel
