Hi Glendamary
Firstly, when you used the value emulsion as a sealer did you water it down to form a "mist coat" - anything from 15-25% water depending on quality (consistency) of emulsion ?
If not watered down it may effect the bond between the new plaster and emulsion and lead to flaking of the finished painted surface
I would suggest that you give the problem wall a quick rub over with 180 grade paper and then wipe down with a damp cloth, frequently rinsed out
Buy Dulux Trade White Undercoat (this is an oil based undercoat) and give the wall 1 coat using a short/medium pile roller
Follow the drying times on the tin and allow plenty of ventilation - as oil based it pongs !
If the green paint is still highly visable, give a 2nd coat of undercoat
Once dry, 2 top coats with your emulsion and that should solve the problem
Dulux is much more expensive than the B&Q stuff but is quality in a tin
Let us know how you get on
