hey guys

looking for a bit of advice.

Had my walls plastered in June and cracks are starting to appear. I used deluxe endurance for paint and it hasn't stuck to the plaster very well. so when it cracks the paint flakes off.

I've used the crack but need to get the paint to stick on the joints

has any one got any advice

HI there, it looks like if you sand it back a little bit you could then use some quick dry polyfilla to give a quick skim over the cracks. If you use the kind of filling knife used for jointing https://www.amazon.co.uk/Marshalltown-5 ... ting+knife that will help spread the filler over a wider area. The reason for the quick dry filler is that you can sand it down quickly then apply another coat if necessary. Then paint as normal with the Dulux.

did you mist coat the walls before painting..??

no I didn't mist coat. On the tin it said for new plaster but hasn't stuck at all.

it's not the cracks that's the problem it's where the paints flaking. I need to some how get an edge on the existing paint to be able to make it look OK

I see 3 colours in your photos. The wall colour, something lighter (what is that? filler?) and the plaster where the paint has flaked off. You did not "mist coat" the new plaster. Did you by any chance put a coat PVA on the new plaster?

Mist coat is a coat of diluted paint designed to penetrated into the plaster and bind with it. Putting a full strength coat of paint on unsealed plaster means that the paint will always be likely to flake off.

=============

Unless you have PVAed the walls you seem to have two choices. Keep scraping the paint off (maybe easier than you think) till you have done the whole wall (other walls may have a similar problem) and then mist coat the wall or try to get a solid edge on the existing flaking paint, sand the edge fine, fill as has been explained above, and apply a coat of Zinsser Peel stop on the whole wall (perhaps on the whole room if it has all been done the same way. .

yes the lighter colour is the crack that's been raked out and filled in. Could I put pva on the edge of the paint to get a solid edge?

Not mist coating is probably the real problem..It's a very important coat as it seals the plaster & allows subsequent coats to stick to the plaster.you may have to strip the whole lot off & start again.I'm not sure if peelstop would work as i've never used it in this situation..strip paint,give it a light sand.Then apply a thinned down coat of contract matt emulsion then 2 coats of your chosen paint......As Wine-o has said do not use PVA.

if I'm honest I'd like to try and avoid stripping the whole wall. it's the staircase wall and it's pretty big

I've had all 3 of my bedrooms
replastered and no mis coat put on but they've been fine. Albeit cracks appeared but the paint didn't flake

We're barely a day into the new year, and it's reared it's ugly head already! [emoji15] [emoji15] [emoji15]

As said not mist coating is likely 99% of the problem.. Zinsser peelstop has got to be worth a try.

First though lightly sand and "feather out" the edges where the paint has already flaked off.

The paint probably flaked because it was at its thickest at that point. How well the paint holds, you will know the next time you repaint the same walls. For now - as you are looking for the quickest way out - all you can do is try to get a solid edge where the old paint does not curl up and is ready to flake, feather the edges and fill the in-between space, and then mist coat the filled area. You may or may not get away with painting only over the filled area, it depends how easily pleased you are.

BTW. Did you do the plastering yourself? 'Cause we all know painting is worth a 99p tray and roller from B&Poo and anyone can do it (I am only an amateur painter like you in case it matters).

I'm struggling to get a solid edge just seems like it wants to keep flaking.

no I got a plasterer to do the work. Not to happy really as cracks started appearing everywhere same as in the bedrooms. He seemed genuine enough took his time gave it 2 skims but still cracking

My dad did the painting, he's been in the painting game for a good 30 years. He only put the paint straight on the newly plaster because on the tin it said was good to use on newly plastered walls and plus I'm his son who wasn't paying him lol

Not having a go mate, but if your old man's been in the painting game for 30 years then he should know to put a mist coat on regardless of what it says on the tin.

I had similar problems at home with plaster. I had my walls skimmed but they skimmed over loose bits rather than knocking off back to the brick. I ended up lining my walls because the cracks just kept reappearing.

Best thing you can do with the loose paint is scrape it back and start again with a mist coat.
