Bead board wainscoting in my entry hall. Behr Premium Plus Ultra stain blocking paint and primer in one, interior semi-gloss enamel, ultra pure white, #3750. Best way to apply this stuff? Brush, roller, sprayer? I'm thinking sprayer, but which one that's not professionally priced. I do own a compressor if that makes any difference. I had a Wagner electric gun at one time that was a disaster trying to paint a door. Returned that to HD quickly. Honestly, I HATE painting in general so I need to make this project as painless as possible! I have the paint from another project I am doing now (ugh), unless there are better suggestions. Thanks.

My son has engaged a contractor to paint an aluminum sided house in Columbus, Ohio. I was at the site today and talked with a painter who was working alone at that time. I asked whether power washing had been done. He said he had washed with an electric washer, which, according to him, is less powerful than a gas powered washer and was chosen to avoid hitting the metal siding corners and possibly causing them to come lose or off of the house. We did ask that washing of corners be carefully done because a few lose corner pieces had been detected. Otherwise, extra precaution was not requested for the regular siding covering the walls. While at the site today, I swiped my fingers across a small area on the south-facing back side of the house. The pigment residue the came off and appeared on my fingers seemed quite heavy. I showed this to the guy who allegedly had used the electric power washer on that back wall. Another person, apparently a supervisor, was present at that time. The worker said he would go over that wall again tomorrow before painting. But, he also said that, even after a washing, lose pigment will remain on the surface of the walls. The photo shows my fingers after I swiped the wall; I believe my swipe spanned not more than 1 foot in length, swiping horizontally across one siding "board". I have painted brick and wood siding in the past but I never painted metal except for the two steel 1-car doors on my garage. I painted them about 29 years ago when they were new. I have not repainted them but I have washed them a few times. When I did this, I could see a milky coloration of the water that ran off the door. And, after the washing, a swipe across the doors would yield little or no pigment coming off and sticking to my fingers. So, I'm very skeptical about what this painter is trying to claim about a significant amount of pigment remaining after washing being normal. Am I right in being doubtful about what I've been told?
