Do i need to seal plaster before painting still?

I had my chimney breast plastered over original paintwork and the fireplace was boarded out to make a smaller alcove. This happened almost 2 months ago and with loads going on, I’m just getting round to painting it, so I still need to add a paint/water wash to it after all this time?

Yeah a 70% paint 30% water mix should be ideal. One coat of that then Normal paint on top

You will still need to give it a white wash, 50 % water 50 % white paint a watered down white emulsion paint mixed up well , then 2 coats of your colour,
If not the plaster will draw the moisture out of the coloured paint fast and not leave a nice finish, hope this helps cheers 👍
