Plastering Question

Multiple hairline cracks appearing after reskimmed living room

Hiya,

Hope somebody can help.

Basically we had our living room reskimmed about 6-8 weeks ago and in the past few days I have noticed multiple hairline cracks, some not that long and some spanning a good distance. The hairline cracks are on all different walls, above picture rails, above where the radiator is and underneath where a mirror is hung and also a few random ones.

I understand with drying out/movement etc this can happen, we have previously had other rooms done and we had a couple appear in kitchen which was just caulked and repainted but not to this degree.

I am concerned that more and more are going to appear and basically will have to have it replastered again or is this fairly normal? We had the work done when it was just warm in weather and now obviously it is getting a little colder. We originally left it to dry out for a couple of weeks before giving it the first coat of emulsion etc.

Any help please?

Yes very normal, skimming is a waste of time on old plaster. It should always be hacked off and completely renewed on a bare brick wall. Firstly with a new bonding coat and then a finish coat.

Hi there,
Sounds very much to me like the wall has not been prepared properly in the first place, two coats of p.v.a should be applied to any surface (old or new), this way the plaster can dry at its own pace and therefore you shouldn't have shrinkage, if the cracks were there previously your plasterer should have taped the joints before he started.
Tap the cracks and if it sounds hollow around those areas then they will always open back up.

Hi
The problem is the moisture in the plaster has been absorbed to quickly due to PVA not being applied or the plaster was applied to thin, filling the cracks with filler will not work as you will just keep getting more appear.
My advice would be take plaster off back to brick work render/board/bond the walls and re skim.
