Re: Hairline cracks interior walls - widen or paint over?
That is excellent advice. I had used something similar in the recent past, not on cracks, but on divots in gyprock walls, and on the rips to the gyprock paper outer, which resulted with the ill informed leaving the blue painters tape on for many weeks (no surprise that it took old paint and paper with it when finally removed) after initial painting had been done. At least it gave me plenty of experience with fixing such problems. However, I hadn’t noticed the CSR 3kg product before. I will certainly have some big jobs like this when I help out at my daughters new (old) house
