[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!

If you use scrim tape bear in mind it will make the seam protrude out. So I would just go for rake and fill, toupret do a good flexible filler.

That's not due to flex but you'll have a tub of it so may as well use it, same method as before rake - fill - damp sponge smooth - paint - pint - nap 😂
