If I have already primed all of the plastered walls with SBR (Everbuild from Tradetiler), is it advisable to apply Mapei Primer G on top of this prior to Mapegum, or do I just tank straight on top of the SBR?????

Thanks - Geoff

If it says use primer G, then why haven't you used it..?....the sbr should be fine but worth checking with mapei to see if the mapegum will adhere to it.

I havent done it yet, hence why I have posted the question. Just wasnt sure if the Mapegum had to be on top of Primer G or if it would work with SBR. Will ask Mapei

Mapei g will not absorb into the sbr

So I take it that it will be ok to do it then?

I would just check with mapei as Dave reccomended
