Hey guys, I've something similiar on my wall and when i just tugged a small part of my wall that is peeling, a good portion of the paint easily detached itself from the wall..... Should I just rip off the entire thing? Also, if i rip if off, the concrete beneath is exposed. What should be my base layer? Primer? Plaster? Sealant?

Hi all, Im just got a 3rm resale and i'm planning to DIY paint the house... There is one patch on one of the walls with the paint already peeled out and the edges are like popping out of the wall as though there are air space inside... So do i scrap the old paint off????? sounds very tedious? I heard the paint pops out cos a sealant or something wasn't used? What should I do? Or how should i get started? from all the previous posts, i gather that these are the steps i need to do: 1. patch and smooth the walls using wall putty 2. sand paper the walls 3. plaster the walls 4. emulsion paint (2 coats?) 5. paint (2-3 coats?) ** start with ceiling first...(and wear showercaps and gloves!) Have I missed out on anything? Any good brushes/rollers to recommend?
