I'm laying (NA) on the DPM tomorrow..., so as per Ardex recommendation I guess I'll now have to apply a primer as its gone past the 16 hour mark....
Definitely prime it first, rs should always be primed on a Dpm as its not as good as n/a hence its always been a bit of a suspect on ceramic tiles from experience....... N/A every time
Last time I used RS NA didn't exist it's was all eye watering Original yellow and black bag back in the day
Yep remember when it was yellow and black like you said like chopping onions when putting it down, as where all the really cheap screeds 10 yeas ago, all rammed with ammonia
