Unusual lump appeared in wall.

[Donnie Murdo]

Found this on my wall the other day, it had pushed the wallpaper out and when I removed it, a lump of plaster came with it with the dark bit in the middle. I noticed a post from 2020 with the same but no solution was added. Would I just fill again with plaster or leave for a period of time to see if anything else happens Before repairing?No dampness at all. House was built in the 50’s. Appreciate any help.Thanks.

Seems like a lump of plaster has come away from the wall and took a chunk of concrete block with it

see it happen a lot with those type of blocks, material that’s used in them causes it to expand and pop off. Whether it’s iron ore or what I don’t know, just patch it back in it will be fine. Scrape the centre dark patch out first.

Thanks for replying…. The centre black bit is like powder when you scrape it, I just wasn’t sure whether to repair it or leave for a period of time. . I’ll get onto it and no more appear. Thanks again

It’s expanded and pushed out as the lump is slightly larger than the whole in the wall …thanks for replying

Use a smaller drill bit when putting pictures up next time!

Oh dear…. Being a ‘woman’ I thought I had to use the largest drill bit… I’ll know the next time. Here’s a tip for you…. Use the wee Velcro type strips… they work amazingly and leave no marks

Don't know, but suspect the dark stuff is unmixed fly ash thats got a bit damp and expanded

Been a thread on here before exactly the same


I've seen it myself quite a few times.


I think it was blocks from the 60s?, might be organic or something, swells and pops.

Had this happen in my last house. It turned out it was some sort of nest that had laid dormant for many years. Then popped out . And infested the whole house with tiny poisonous spiders. . But shite happens. X

That’s what it seems to be, 50’s ex council house. My daughter bought the house next door and I think she could be spying on me
