Hi, yes it’s definitely my fault. I applied 2 coats on walls and ceilings. It looks perfect on the walls and I just want to repaint the ceilings with supermatt and leave the paint as is on the walls. Will supermatt stick to the vinyl matt?
Hello, a couple of months ago I repainted my walls and ceilings using Dulux Trade Vinyl Matt watered down by about 15%. I love how it looks on the walls but the ceilings look terrible, extremely patchy. Can I paint supermatt over vinyl matt or does this require special preparation?
