Hi everyone. I’m a complete novice to plastering so any advice would be gratefully received. I had a crack in my plaster so I removed all the blown plaster and patched this part and then skimmed the whole wall. There is a radiator on this wall and I’ve had the heating turned off since I started patching the plaster to let it dry naturally, but I’m just wondering how long I should leave the heating turned off completely? I don’t want to turn it on too soon and affect the plaster and cause cracks. Thanks
