Iv just put laybonds one coat dpm in a kitchen today going back tomorrow to screed with balls 300 aim going to prime with [h=4]Screedmaster Universal Primer which is brill but do i have to use balls 131 primer which on dpms you have to use it neat and i find it peels off when you stand on it .

Can't see it making much difference tbh mate . Should be ok. I know what you mean about the Ball's primer though , it's forever peeling off a smooth surface
Been using ball primer all year and its great now, you must have a old one as not had it peel off a dpm or ceramics this year
you should stick with a system. So as you used laybonds DPM you should really be using laybonds primer and screed compound also. As you are using FBALLs screed then its irrelevant on if you use fballs or laybonds primer. It now a mixed system so any guaranty is void so to speak. if you want to mix systems (and i have done in the past myself) then dont expect a guaranty. So your choice on what you prefer to use!
