No, it wasn't. The Zinsser ceiling was supposed to be the primer, so I didn't assume it needed to be primed/mist coated before (by 'mist coat' you mean using the final paint in a thinned consistency, right?).
A mate suggested I could try using PVA glue first and then Zinsser on top. Is this advisable?
Could the plaster have been too smooth - do I need to sand it first?
Many thanks!
Just bought a house and redecorating before moving in. The bathroom ceiling seems newly plastered, and I wanted to paint it over before starting to use the bathroom. Started off alright with skimming polyfilla over some minor holes and wiping down the ceiling with a damp sponge. Next day...
