No need to SBR bare plasterboard but for painting bare boards it's best to roller on a mist coat first - very diluted emulsion (assuming you're using emulsion?).
Can't say I've ever painted bare plasterboard before but I guess it will help, same as if it were plastered.
What about painting over plaster?
What primer would everybody use or would you just use a mist coat?
I've always just used a mist coat but wondered what the right way to do it was?
I use a drywall primer on certain walls but find the finish isn't as good as using a sealer.
I find Primers are great at covering up inperfections in drywall but leave a mottled finish
But on new drywall,I find painting over sealer give you a glass like finish.

The texture of the taped joint has nothing to do with the with the finish, painting over primers achieves.
painting over primers give an inferior end result to sealers.
You can paint over drywall primers but the finish will not be as good as using a sealer.
You really can tell the difference the shinier the paint.
Quote from British Gypsum; A general purpose plasterboard primer. The product provides an ideal surface for decoration with most paints and wall coverings.
If you seal it then theres no [FONT=Arial, Tahoma, sans-serif]absorption into the plasterboard because of the shiny surface, the paper surface of the plasterboard has a different absorption than the joint filler.[/FONT]
I think were splitting hairs now.
Both will work, I use a lot of bathroom paints which tend to be shinier than normal emulsion, and I really do see the difference. Next time you paint just give sealers a go, see what you think.
Going to have a look at what British Gypsum they say about sealers.
