Priming kitchen walls prior to painting

[Peter76]

We've recently started a face lift on our kitchen, its one of those jobs that seems to have escalated. When I took the old tiles off, some of the paint started peeling off in strips like wallpaper down to the plaster. So... 3 days later having bought a scraper I'm left with mostly bare plaster walls with area that have chiseled type finish due to scraping. There are also some ares where the paint would not scrape off leaving a ridge, difference in level between the painted wall and plaster. My questions are:

1) Do I just prime the wall like I would any other in the house using a watered down emulsion paint 50:50 before painting with a kitchen/bathroom product

2) What is the best way to avoid any area where the remaining paint won't srape off from bubbling ?

3) Is is best to sand the edges of the patches of existing paint so no unsightly layesr/ridges show?

Appreciate any advice that can be offered. [/img]

Sounds like the original plaster may not have been primed properly before it was painted; for priming bare plaster I thin 25-30% 2/3 coats in quick succession, dry over night & then your chosen finish. However you will now have a very uneven finish & primer & a couple of coats of fresh paint will not cover it up to give an acceptable finish;

2) What is the best way to avoid any area where the remaining paint won't srape off from bubbling ?

Why you think it will bubble! If your getting a reaction there is something wrong.

3) Is is best to sand the edges of the patches of existing paint so no unsightly layesr/ridges show?

You could try a sander to feather the edges & this will work on small local patches but if the whole wall is like a patchwork quilt you’re bound to see it; ideally you should remove the rest of the paint or if it’s securely bonded, have the wall re-skimmed. Don’t be tempted to resort to masses of filler, it’ll look awful & will only create problems for some poor soul in the future.
