SWMBO now wants it a light beige.

Any tips for blocking out the green before the beige. Is just a few
coats of white emulsion the only way?

Lining paper?

three coats of F & B emulsion will cover anything



As long as it's the same colour? :-D

It took about 3 coats to get the deep matt green we wanted at the time.

Exactly. I've repainted most of this house last year and 3 (fairly thin
rolled on) coats was what it took to achieve a color change of any sort.

So even if you start with white it will show through 2 coats.
