How to repair crack/peeling on plaster wall

jonny2510

We re-painted our kitchen approx 12 months ago, and at some point maybe 6-8 months ago, a crack appeared, and the plaster (or skim??) on the wall started peeling (see pics below).

We're planning on giving the walls another coat (we made the mistake of painting matt instead of silk). Can anyone advise what the best way to repair/cover/patch up would be?

I'm not sure if it's relevant, but at some point before we bought the house, a doorway was filled in (which may or may not be where this crack/line has appeared).

Its unusual for there to be any difference in durability between matt and silk. You can get it between brands but if you say buy dulux silk or dulux matt they will be the same quality. Matt is usually better for imperfect walls as it doesnt highlight bad spots with light spots.

Ideally you want durable paint in your kitchen. Doesnt need to be kitchen paint but a generic matt/silk whilst it will go on the walls generally wont last as long or look as good as the more suitable paints (hardwearing, wipe clean, moisture resistant, mould/grease resitance etc)

Basically saying using a silk probably wont prevent this from happening.

It looks more like paper peeling than plaster on the photo? Id imagine the problem has arisen from the conditions in the rooms (temp variances and damp) causing the plaster or paper to absorb moisture become more flexible and then dry out again causing cracks.

You can use fillers but think itll be difficult with it not being deep cracks. The best bet would be to remove the loose bits until its only solid plaster left and then re plaster. Bad things is you usually stat with a small area and end up needing to replaster most of the wall. What doe sit feel like underneath?

Looks like it's the paint coming away.

I'm pretty sure there's no paper on the wall (even though it looks like it the way it's peeling).

It could be paint I guess. Or could it be the skim?

Oops, after fiddling with it, it just fell off (see new pics)! What fell off was quite brittle.

Will something like this Multi Purpose filler do the job (I already have some)?

Or do I need something more like this Skim Polyfilla?

The house is 20 years old, and the wall just a partition wall if it makes any difference.

Scrape off all the loose stuff, sand the edges to feather them in. Two coats of Zinsser BIN and then repaint.
