Hi there - read plenty of useful information on this great site plenty of times but this is my first post...
Had buiding works carried out on my kitchen some months ago and have started to paint ceiling and walls but have come across a room full of problems, I think due to the use of PVA;
Had ceiling boarded out and plaster skimmed only for sparky to fit 6 spotlights all in wrong position !
After much discussion the plasterer filled holes and re-skimmed repaired area, leaving a nice even ceiling
Now when I have sealed the plaster and emulsioned the ceiling, just the repaired areas are showing up. It seems that the paint wont cover the repair area, no matter how thickly or how many coats are applied whilst the rest of the ceiling is lovely
Same problem around wall/ceiling junction where old plastered walls were coated in PVA prior to skimming I'm left with a border around the newly skimmed ceiling where again the paint wont cover (The walls were skimmed a month after the ceiling)
Also various splashes and drip marks on the skimmed walls where the paint wont cover (These are probably from PVA used during ceiling repair)
I'm a competent DIY'er and always aim for a near perfect finish, so carried out work in the following order;
Lightly rubbed over walls/ceiling with 180 grit sandpaper
Wipped down walls/ceiling to remove dust
Sealed walls/ceiling with watered down emulsion - 60% paint - 40% water using Wickes trade matt
Painted walls/ceiling with Dulux super matt using short pile roller
I've seen posts discussing staining when painting but I'm sure that this is due directly to the use of PVA - Definately a bit of a "Marmite" product
Any advice would be much appreciated as this has totally wasted and spoiled my weekend - Cheers
