Had to sand away some flaking paint on my front door (double glazed) and before I paint it a different colour, do I need to fill in the bits where the paint has flaked off and hence left a small pitted spots? Wasn’t sure if I need to keep sanding until it was completely flat, or if I had to fill or if I can simply do a couple of coats of paint and they will flatten out themselves? thanks for any help.
Keep sanding. Then a few coats of coverstain as high build and de nib between coats to make smooth. I'd avoid fillers and use primer to build out and smooth
