Dealing with old layers of paint?

[robodelfy]

I'm renovating my kitchen and have found a few patches where the paint was chipped a little, and I scraped it and a patch came off here and there. But the rest of the pain is still solid and doesn't scrape off.

I can't actually see a few of layers in places, white then pink and yellow!

What's the best thing to do on this situation? I can't scraped back the whole room! But if I just paint over it you'll see it.

I've put a photo for an example

Thanks

Feather the edge , then you won't see it

Sorry I'm a bit of a newbie, how do you feather the edge? I've tried sanding it but it's never smooth

That's how you feather the edge, you're basically removing the step from the paint edge to the plaster so you won't get a line when you paint over it.

Ok I didnt have much success with 120 grit, maybe I need to go finer
