i've read quite a lot about this on the internet and realised its
probably the wrong thing to do. however i thought i'd try it and see
what it does as i'm not that concerned about things being perfect. i
painted the new plaster area with 1/2 pva/water and its left a clear
coat of pva, which is tacky but then shiny when dry. as a painting
surface its very smooth and not absorbent. i painted some of it but
wasnt happy with the way it was going on. its kind of nice when the
walls absorb the paint, so you dont feel you're slapping too much on.

after i did it i thought it might be a bad idea and thought, well can
the paint/pva be removed. well yes, it can, with hot water, a cloth
and a lot of elbow grease. so i've got a small area back to plaster
with the pva/paint gone. thats only about 1/4 of what i painted
tho.

so i'm probs just gonna finish the painting leaving the pva on. if i
could start again, id go with the watered down (but mixed well) matt
emulsion

You're supposed to dilute it 1:5 or 1:6 for sealing porous surfaces, which
won't leave any visible trace.
