Ok, so just give it a chance to dry properly and then paint as normal? I am hoping that it cracked again due to being above the rad! Rad off now.
Yeah put plenty of PVA on the whole wall 5 full coats should do the trick then seal that with 3 undiluted coats of bitumastic paint.
To help you out as you are obviously struggling and I don't like to see a Buddy struggle, would you like me to supply for free the PVA and Bitumastic paint and apply it out of the goodness of my heart all for free as well? Oh! and I'll splash the wet bitumastic with sharp sand before it dries as I find this method gives the paint something to adhere to.
Message for toolpc, Thought it was you who liked filling cracks as you've filled more than a few this week.
Sorry I didn't realise you are a Tory I'll change the word splash to blind, trouble is I was trying to keep the wording simple so you could understand.
