Hey guys, I know this question has been asked a couple of times but I just wanted to check as my question is a little different. I’ve hung lining paper up in a room that I want to paint over. As a novice I’ve got a few gaps around the seams. I’ve read that you can fill and file this down (I have Polyfilla and no nonsense filla- are these ok?). Elsewhere people have advised painting with emulsion first and then filling so the sanding doesn’t rough up the lining paper. I plan on using a very dark navy blue on the walls and wonder if I should stilll paint before and if so should I just do a proper first coat with the dark paint, fill then sand the gaps, and then finish with a second coat? Any advice would be great!
