Hi, just painted the bathroom, first time doing any painting of any sort.
Walls are new plaster but have been drying for 2 months, so not worried about moisture from that point.
I've used Armstead Trade Contract Matt as a mist coat, diluted as per instructions, waited a couple of hours and used used Dulux diamond eggshell on top.
Both one coat each.
I didn't sand the walls, and I've woken up having dreamt of the paint having peeled and piled on the floor.
YABU - Don't bother with a second coat as it will peel off. Sand back to plaster and start again.
YANBU - Should be fine, carry on with second coat.
Thanks.
