Hi, we recently bought some new pine doors (no previous paint or stain) that we are in the process of staining. We lightly sanded the doors before we began staining and wiped them clean with a tack cloth. We stained 3 coats with minwax using a brush two times and a 100% cotton cloth the last. We noticed that there is a chalky/white appearance to parts of the doors and frames. We tried sanding the doors lightly to remove those areas but its just making the problem worse. Any ideas? We need to get this project done before baby #2 arrives in a couple of months!!
