New Plaster Cracking after 2 months

Question

I have just had my kitchen diner replastered and there are new cracks appearing in the plaster. This started on the ceilings and I have now noticed  a hairline crack down one wall. Is this normal? Can I ask the trade back to fix or is it expected and how can I fix it?

Timothy · Accepted Answer

Hi there, cracks should not be appearing especially after 2 months , cracks are due to a lack of preparation and quality of finish, I suspect it has only been one coated instead of two and probably no scrim tape applied and no floating up done. My advice would be to ask the person/company responsible to do it all again properly or to save any further hassle get a proper plasterer to do it. You can cut the cracks out and fill them but it won’t last for long. I hope this helps 
Regards

This is due to house movement. The plasterer would not be liable for this, I have my own property that I plastered myself and the same thing happened here. The best resolution it's to fill sand and repaint rather than pay again.

Jason · Answer

Usually happens when the plaster drys too quick so maybe you put the heating on too quick and didn’t let it dry naturally. and yeah it can be fixed easily with a bit of easy fill.

Hi there 
Cracks can often appear on new plastered walls and even ceilings! 
Whoever did the plastering should have used a bonding material i.e. PVA or unibond.
If not applied then it can crack, but you could always fill the hair line crack with a filler.
Hope this helps

There’s a few reasons why this could happen:

• The wall may not have been prepped properly before plastering the wall
• If there’s movement in the ceiling, this could cause it to happen.
• The plaster could have also dried out too quick if the heating has been on very high. 

I’d suggest calling your plasterer back and discussing with them.

No it’s not normal for the new plaster to crack my thoughts on the ceiling could be either not enough screws so when walking above the floor areas this is making the joints open in the boards regarding the walls it may be the relevant seal was not mixed correctly so there for the plaster in certain areas have become weak.

Clive · Answer

It could be due to heat / movement, all joints should be scrimed as well. If the cracks get overly big I would call them back.

Hi Angie, it is normal for new plaster to get hairline cracks as it dries out due to the material shrinking. It is especially prominent around ceilings if you have had new plaster boards put up.  As long as they are hairline cracks then you are fine, if they are more than hairline cracks then you should be able to speak with the plasterer and ask him to pop back and assess or you could put a little Decorators caulk in them,sand then a little and re-paint.  

Hope this helps

Unfortunately it can happen and its not always down to bad plastering it could be settlement cracks. If they were bigger than hairline then its sometimes down to movement. Its a case of rake the crack out and fill it with filler as its lighter and deals with movement better

Jamie · Answer

First of all are you aware of your building moving etc? This could have affect.

Second of all definitely get the guy back to take a look. 

Failing that then he’s not done the job properly. 

Cracking can occur but it does rarely happen. 

Ceiling cracking could be down to scrim not being applied on old cracks etc and then reappearing. 

Cracks can appear if the preparation of the surface was not done properly. PVA? Or BOND IT.

James · Answer

You can request the company come back plaster sometimes cracks above door frames or on ceilings. This can be due to furniture above the ceilings being moved about but if it has cracked within 2 months on a wall I would advise you call them back
