Painters advice:
Using a water based paint for my walls, first coat went on lovely but when dry I noticed on most of the walls little air bubbles (some as big as a fifty pence piece). Let it dry and I sanded them down which worked. Upon painting second coat most of them bubbles have reappeared?
Id love to know you're thoughts/advice for treating as I'm thinking the walls where never plastered...just plasterboarded and joint taped and Mabey the paints seeping behind the paper on the plasterboard causing bubbles? See pics...

Did you dilute the first coat with some water?

No just gave paint a quick mix and painted, it's weird

Diliuting it so it penetrated into the joint filler instead of causing bubbles may have been better
