Plaster sealer or just a mist coat?

Quick update; it worked a treat, thanks all for your advice! I did a mist coat all over then two coats of colour, and returned my plaster sealer to B&Q for a refund.

Gingerninja72, I mist coated my study ceiling with a 70/30 paint and water mix and it worked really well and not too much dripping.

Cheers

70:30, assume you mean paint:water…?

It won't be happening for a couple of weeks, but thanks for the advice

Yep, 70% paint, 30% water.
