Yesterday I painted a picture rail with white gloss and next I'd like to paint the wall with a different paint so I need to cover the picture rail. The problem is that the gloss paint feels not exactly sticky but it does feel like there's some kind of adherence when you touch it. It's been almost 24 hours. Mum says that last time she had gloss on the stairs banister it stayed sticky like that for a week. Is it too soon to put masking tape on it?
