What Liquid Damp Proofing before applying Tile adhesive ?

[Spinny]

So I want to use tile adhesive on a horizontal surface after applying some kind of damp/waterproofing to it.

 

(Yesterday AI recommended DryBase Liquid-Applied DPM saying I could apply tile adhesive while it was still tacky. Today it says the Drybase has to dry completely and then I may need a primer. Useless thing)

 

What can I use and still get a good tile adhesive bond (Using Mapei Super Flexible Tile Adhesive - powder S1) ?

If you are doing liquid dpm, do yourself a favour and use a 2 part epoxy based system. Easy to apply, chemical hardening, so sets in a predetermined time. Apply one day time the next. None of the tacky nonsense. Not cheap but works well.

Why not tank the surface?

It is only a small area. A physical DPM is going to interfere with getting a good bond.

Not very likely to get any damp but would prefer to use something rather than nothing. People must want to liquid damp proof floors and then use tile adhesive all the time - what do they use ?
