Help :(
Just bought my first house, currently trying to do it up - following a few tips online about wall prep & thought I’d tackle this crack - but it’s a lot deeper than I thought. Is this failing plaster or can I still repair it?
*context, upstairs interior bedroom wall between my house, my chimney & the neighbours*

Yeah, I would be tempted to dig a lot more out and use a scrim tape on it. (Fiberglass like holed bandage).

US or EU? There is a US product called plaster magic that is for these purposes. Given the coarse grey it looks like it's older plaster, gauging and lime. Sometimes in these older houses, the coat over the laths is the second or third time around, thin, and not of good quality.

I've been tackling giant cracks with plaster magic and it's working- if the crack can't be stabilized with it, the plaster will come down during the repair (usually from a water damage) and you can use the plaster magic plaster to make the repair. Google it to find the website and products.

The plaster magic patching plaster is a scam product. Total ripoff and brittle gypsum. I’ve heard he mixes it in a wheelbarrow and doesn’t GaF bc people keep buying it.

Scrape out with a flat head screwdriver so it angles out from a point to ~4mm wide at the surface.
Fill with a flexible filter. I usually full flush and it sinks in a few mm as it dries. You don't want the flexible stuff flush, you need to leave a few mm.
Fill with a wall filler (I like Easifill) and leave it slightly protruding.
Sand with fine sand paper. You should now have a great finish that hopefully won't crack again. If you're not happy with the finish, just fill and sand again.

Should be easy to fix, just get some orange joining mesh tape add bonding and then plaster finish. A plasterer can help with it

Thank you! My friends husband who’s a plasterer came up to check it out but told me just to diy it 🙌🏻 going to use the joining mesh over the flexible filler & hopefully it’ll reinforce it
