How would you fix this (picture attached)

Hi,

We are renovating our house, it was all taken back to brick, boarded, skimmed and we've starting painting that walls. We've painted a first coat with watered down matt emulsion and a second coat with matt emulsion.

On one part of the wall there were some 'splashes' on the plaster before we painted (at a guess it was PVA splashes), we didn't think much of it because when I ran my hand over it, it felt smooth and flat. The first coat the paint didn't take as well as over these splashes, we did the second coat at this hasn't either:

Its link the paint is thinner over the splashes so the paint isn't flat. I don't think putting more coats of paint over would fix it.

How would everyone else fix it?

Any help much appreciated
Alex

Filler and careful sanding will sort it out, trying to paint over will take too long and too many coats and probably won't help anyway.

You need to check the surface is sound before you do anything, pointless trying to do anything on an unstable surface contaminated by PVA.
