I'm using no more ply however there is no SBR primer in the tile shop so they gave me evostik. Is the 918 evolved primer the same stuff as the SBR recommended for the ply. There's just something at the back of my mind telling they are the same primer. I forget where I heard this not being the same, either someone mentioned it to me or I've read it on here.
Another thing, isn't 915 ok for laying the NMP on 1 hour after application or is it best to wait the 24 hours for full dry.
