Plastering & Rendering

Cracking in plaster where doorway was blocked up

Anonymous user 28/02/2024 - 3.57 PM

Hello, almost 2 years ago we had a double doorway blocked up and then plastered to make our living room a separate room. They only plastered over the bit that they had boarded up and it looked terrible so we got them back and they skimmed the whole wall. It wasn’t perfect but we just accepted it after all the disruption and I didn’t really want them to do anything else to our house. We noticed very fine cracks after a few months but they have got worse and you can basically see where the doorway was on each side of the wall because of the cracks. What is the solution to this as we have already spent a lot of money on this. Will it get worse? The cracks started as a very fine hairline crack but they seem to be more prominent at the moment at different levels. I think it might get worse in colder weather.

Are you a tradesperson and able to answer this question?

Hello Jenny I suspect that your plasterer may not have applied scrim tape to bridge the joints/gaps between the boarded up doorway and the surrounding walls. As a result the joints are ‘weak’ and cracks have appeared. Scrim tape is used to bridge the joint/gap between two or more surfaces, preventing cracks and weaknesses from occurring once these gaps have been plastered over. You should have the wall re-skimmed, ensuring that scrim tape is used over any joints/cracks, if you want to deal with the cracks properly. The alternative, which is far cheaper (but may not work), is to rake out the cracks, vacuum, apply PVA and then fill with gyproc 60 filler. I hope this helps. Regards Tristan

It's been botched. Re-skim the whole wall using a render mesh throughout. You can have a go first with some filler though and see if it remedies it. But unlikely.

If suggest trying to fill your self and see how it holds out before painting failing that have wall re skimmed shouldn't cost to much and your wall will be as good as new and done properly

The plaster might not have put his scrim tape over the joint. Trying filling it your self and see how that goes if not no good get a plaster to re-skim the wall
