Fballs 131

Been do a job today dusty concreate floor brushed and hoovered it of applied some 1-4 let down 131 primer let it dry and gave it another coat let that dry went back in to start to screed and it was pulling of like skin anyone else come across it or no why it did it or even any other primes that are good cheers

 

131is bad for that, I prefer the Eco prim t or Ardex p51

 

I second that quote Merit same as me that 131 is cack always has been and always will be.

 

All I buy now is the ardex primer P51. That's the best I've used so far. Has a really good bond.

 

Not tried p51, usually stick to eco prim t, how does it compare?

 

Good mate, just works well on dusty floors and neat it sticks well. used it on ceramics other week and unlike 131 it dont come off.
I got a few eco prim t when I got a few pallets of trade and it pin holed alot.
So after using most of them sticking to P51 for now. Laybond one is good but not tried it on ceramic or ashpalt yet

 

Not had pinholing issues myself, but I do like some of ardex gear might give it a try
