Plastering & Rendering

Re-skim wall cracking like a jigsaw!! HELP!!

Anonymous user 15/03/2024 - 2.36 PM

Thank you to everyone that has responded. I called 4 local plasterers, the 1st was too busy, left messages for 2 and 3, 4th was really helpful, happily coming to look at it tomorrow, said whether it’s a simple pva and skim a small area or the whole wall, he always try’s to help! Fingers crossed!! Cheers Hi all. Looking for some advice please. We had a wall reskimmed a few years ago as part of an extension. This wall was not new. In the corner some minor cracks appeared which I planned to fill. The cracks however began to join up and then I simply took a piece out like a jigsaw, it was not bonded to the wall at all? Rest of the wall is fine, just this section which is an exterior wall joining a new stud wall at the corner. Any advice in terms of possible cause, how to rectify and of course - what not to do! Thank you in advance.

Are you a tradesperson and able to answer this question?

It could be movement from the new extension which is coursing the cracking or it could simply be that the previous plasterer didnt pva the wall which can also make cracks appear i would recommend hacking of any loose plaster pva the section thats missing put scrim tape in the corners and reskim

Remove any loose plaster, re-sealWith some thin down uni bond,,tape any joints with plasters mesh, then refill With a suitable filler, this will then be ready to repaint

Hi Call in a local or recommended plasterer. The plasterer will then remove all loose plaster, this may end up being a bit more than the section that is currently loose. Your plasterer will then repair the sub surface, apply skrim tape to joints etc, then apply an adhesive/primer (this can be achieved in various ways, most likely PVA and water), then it's ready for the skim coat patch repair works. 👍🏻👍🏻

It depends on what you want the finished result to look like? I would advise first and formost not to attempt this yourself unless you are competent as it could end up looking a mess. Joins into extensions and onto different substrates will always be the first place cracks appear as the expansion rates differ in the materials behind the plaster. It isn't a big job for a plasterer so I would advise just to call in a professional. Don't worry, I don't think your house is falling down, which is often the first thought upon seeing cracks.
