Hi guys! Thanks in advance for any advice given. My question is related to priming and painting new wood doors. I will be starting a job in January and want some advice. I will be painting a 3000 square foot home. I will be priming all surfaces (freshly drywalled/mudded walls and wood trim and doors). The doors will be hung by the carpenter and I'm wondering what your thoughts are on painting the doors on the hinges or taking all the doors off. I believe they are solid wood and so will be quite cumbersome to take off and paint in another space. My intention is to prime all the doors with the shellac based BIN product (I like it because it rolls on real easy and dries super flat, it's also easy to sand before top coat). Then I would like to spray the doors with a latex product. I'm considering purchasing the graco 395 for this project. Can I spray the doors vertical? Is the BIN product a good primer for this application? If spraying a primer coat do you need to backroll in order to work the paint in? I'd like to make use of the sprayer as much as possible for this job.
