What acrylic primer?

[J Sid]

I'm pretty sure bal don't recommend using primer on ply (the tiled surface) when using bal single part fast flex...

as Weber say the same, backs and edges only

They might not specify it as required but I bet if you asked them if it was OK to do they would say you can if you want .

No, they say 'do not prime surface to be tiled'.......should imagine it will fail.

I've looked at bal spec . Yes your right interestingly although telling to prime as you say it's only on wall application they say do not prime so I don't understand why that should be any different to the floor . I think a call to technical is required to explain why.
