If painting over (old) gib, get a sealer thats designed for this .

I learnt that the hard way , made one hell of a mess of things .

 

I think Resene Pigmented Sealer seems to be the best product for this sort of thing after a bit of research. Still there is so many products available it's hard to know for sure.

What happened to you?

Have just used the Resene pigmented sealer all over the ceilings from fly s$%t, workes extremely well and was very easy to apply
