Hello,
I've just built some shelving using MDF and have just encountered some kind of paint incompatibility the like of which I have never seen before.
Specifically I primed the shelving with Homebase own brand wood and metal primer (oil based)....but when I try to apply a top coat the paint has been repelled as if I am trying to paint wax!! On this occasion the top coat is Farrow and Ball "Modern Emulsion"...which is water based and 'kin expensive.

What the heck is going on?
