Do I need to sand previously varnished doors before painting them?
I am painting the interior doors of my home. The house is 55 years old and the doors are the original blond color that was popular in the 50’s. I have already sanded two of them and am having trouble with a yellowish stain bleeding through the primer. I have done several coats and the stain still shows.
I sanded and painted a bedroom closet door and did not have this problem. Should I not bother sanding and just paint? It sure would save a lot of time!
