Crack alongside cable casing (pic)

[DeeEyeWhyBecauseIGotta]

Hiya! How would you go about fixing this crack? I think there must be wires inside it.

Just run a bead of caulk down it

Decorators caulk, make sure it’s paintable. Watch a YouTube video or there’s a fab decorator on TikTok, I will see if I can find her link.

Ok, I can’t find her doing a straight line, but she shows how to get a smooth finish before painting and says you can use this method with all your filling so hopefully you get the idea

Thank you so much!
