Filling cracks in plaster - ? skim or lining paper
Discussion
Hi Pistonheads
Please see pictures of inside kitchen wall which was newly built 3 years ago. All is structurally ok but it has had 2.5 years to dry out now and I 'm not sure what to do about the cracks that appeared a few months after drying out when radiators were on.
We used Sika in the mortar mix beneath the plaster to stop damp from the ground and I think the plaster has cracked where the Sika ends i.e. half way up the wall.
Now I just want to address the cracks. I am hoping a reskim would do the job but not sure if cracks would come back? Someone said I would have to put lining paper on wall, which I don't want to do.
If I do skim how is it best to address the cracks first please?
Thanks for your thoughts

New Build ?? Was it sand & cement render then skim, Normal new build is dry line and skim, You say you used silka ?? was that in the render mix , , Is it only the top skim coat whats loose (cracked) or is it hollow all the way back, Anyway I would just rake out and fill , sand & paint.
As others, scrape out and fill. I tend to use plaster rather than a filler. Never done this myself (most of my work is limited to where I've had to create access to behind a wall for cabling) but a tip with fibre glass is I think to drill a small hole at the end of a crack to stop it spreading. May be pointless on a wall but can't hurt.
Be prepared for a lot of sanding and dust. Paint after with a roller to get the same paint texture that was there before

Thanks for all the feedback everyone, I think I will have a go when I don't need radiators on, as will have to remove them...
The plaster was skimmed to plaster board and behind this was a mortar sika mix on top of breaze blocks...
Just wondering how far you scrape out...? not easy to describe I suppose
