Newly painted walls - then cracks appear the next day!
Anonymous user 23/02/2024 - 2.46 PM
Hello,
I've recently moved into a 1930's semi and started to decorate. I was painting over magnolia, so I gave it a coat of white emulsion with a roller, left for a couple of days, then painted over with a cream dulux paint (again with a roller). Came back today, and cracks have appeared on various walls, from ceiling down to the floor, and across horizontally. It looks like I could get a finger nail and start picking it off!
Should I put another coat of paint over it? Or fill it then paint?
Nb: I'd already filled a couple of existing cracks with filler, sanded, then painted and the cracks have reappeared over this!
Same thing has happened in ceiling, when I started painting, big chunks of flaky paint/plaster were coming off.
Any advice would be really useful.
Thanks
Are you a tradesperson and able to answer this question?
Hi, 1930 house possible has distemper on walls/ceiling as this can cause this effect, if your roller is also pulling it of with suction, may even be incompatability betweens paints,
only answer is to remove paint/distemper, then paint 1 No coat sealer followed by your choice of paints.

Chances are the application was incorrect.
with newly plastered walls you must give at least 3 coast ( depending on colour).
1st coat should be a very watered down mix, apox 30-35% water.
this coat will suck into the new plaster.
after about 24 hours- you can then apply the other two coats.
if its emulsion, which i gather it would be.. use about 5-10% water mixed in.. again depending on colour.
1. do all your cutting in first.. ceilings,windows, door frames etc
2. then using a medium pile roller you can get a nice even finish.
3. when rolling don't forget to "backroll" with your dryish empty roller.
this will remove any "tramlines" or roller marks you may have initially applied to the surface when the roller was full of paint.
4. When rolling:
load your roller and roll from bottom to top.. if done the reverse the roller sleeve (which is full of paint) could gather like a sponge and in effect wring out the sleeve and cause paint to fall to ground.
5. cut in, roll top to bottom, back roll, reload and begin again.
Time is a factor, if the process is rushed then the walls will not dry back correctly and in the drying process it could then crack and in most cases could peal off in sheets in time.
Hope this helps,
Sean.
