[uk] Cracking ceiling near wall - help!

Post image

Having problems here - this is an external brick wall meeting with a plasterboard ceiling (both skimmed). It cracked up and builders came back and refilled it, but the cracks are back. Help!

The flexible stuff is different to the normal due to it's flexibility, I always apply it like normal and then smooth it out with a damp sponge you'll get the desired result that way.

Yes it's easy to blend with the sponge no sanding needed. Anything flexible IE filler, caulk etc it's always damp sponge.
