Jut finishing off the tiling in my kitchen and I have only the window
box left to do. The Plaster surface was a bit uneven and raw so I have
sealed it with a PVA solution and let it dry.

Suddenly wondered if that was the right thing to do? Or Am I going to
have to scrape it back to bare plaster?

IME letting the pva dry doesn't make any difference.
