Plastering & Rendering

Fresh skim looks like cracked glaze in a few patches, safe to paint or unsound?

Anonymous user 03/03/2024 - 3.27 PM

Hi, I was hoping I could upload a photo as it would visibly explain my issue but it doesn't seem possible. So here goes, we have had a room plastered which for the most part is ok, however there are a couple of patches where the best I can describe is that the finish looks like cracked glaze and doesn't feel smooth. I'm no expert but I'm thinking it maybe dried out too quickly and the old surface possibly wasn't sealed sufficiently/correctly? It's a 1935 house and we had stripped back to the original plaster in that room. Wondering if I can seal/overpaint of if it would need to come off and be re done. Any advice most appreciated.

Are you a tradesperson and able to answer this question?

Yes the plaster has gone off to quick many reasons for that some off us call them spider Webb cracks you can fill them with eames as long as they not blown and they will be fine

Hi, if you tap it with your fingers and it sounds loose or hollow then yes it would need to be patched or reskimed. But chances are it's just dried to fast but should be fine to paint

I usually find this tends to happen if the substrate is not properly sealed, which will suck the moisture out of the fresh plaster causing it to fail. Have you tried tapping the area to see if it sounds like it may have popped? Potentially it could be fixed by cutting the effective area out (back to where it isn't cracked or blown) seal properly and patch repair. Unfortunately just painting over it wont solve the problem.

Scrape back to old wall double pva or blue grit then re do checking the cracks don’t return then keep an eye on it while it drys hope that’s good
