Cracks in wet plastered walls

Question

Is is normal for newly plastered walls to have drying lines and cracks all over them?

Nathan · Accepted Answer

New plaster should not have cracks in it at all unless the background is moving.. but also if the are hairline  cracks could be being dryed out to fast

Lisa · Answer

No this is not normal this can mean that the mix was not made or applied  correctly.

Thanks

This can happen on plastering jobs, where the background plaster e.g "horse hair" plaster has not been adequately primed. Although old properties with this type of plaster even if primed properly, can still suffer with hairline cracks. The only way to avoid this, is the remove old plaster and start again.

If the cracks are above doorways or windows these are stress cracks from when doors windows open and no real  way to treat them other than raking  them out and fill this may happen again over time , if there is cracking all over the wall this could be due to poor preparation lack of primer using the wrong primer if any at all and there for the plaster drying to fast it may not have shown any slight cracks whilst the plasterer was there it’s possible these have formed after the job was done when curing , if it’s so bad that the plaster is no longer adhering to the backing coat I would call back your plasterer and ask him to remove  the new skim,re prime the wall  and  re plaster that obviously should be free of charge .

Hugh · Answer

no there should be no cracks over the wall on new plaster board work if your skimming a old wall you might get some crack

Oleg · Answer

It is normal for newly plastered walls to show some drying lines and colour variations as the plaster cures.
However, fine hairline cracks can occasionally occur due to natural shrinkage during the drying process and are generally cosmetic. These can be easily addressed during the preparation stage before painting.
Larger or deeper cracks, or cracks following board joints, are not considered normal and would indicate an issue that should be rectified.
The plaster should be allowed to fully dry before any final assessment is made. Once dry, any minor surface imperfections can be corrected to ensure a smooth, high-quality finish prior to decoration.

Martin · Answer

no not at all sounds like the background has been poorly prepared and the new plaster has dried out quickly new work should be flat , smooth , and polished up to receive new paint or paper

Anatolie · Answer

Yes, some drying lines and very fine hairline cracks are normal as the plaster dries and shrinks. They usually disappear or can be filled before painting.

Not normally this is possibly due to suction on the inner linning but if you leave it a week or so to totally dry out then apply a fine filler that should hold .
