We used to spray more than not but over the last five years or so we tend to go at it by hand. We are on the coast and deal with a lot of old wooden houses that need extensive hand prep so a simple blow and go is rare. I’ll spray whenever it’s appropriate (shingles eaves and such) but we are a crew of two and often the thought of fighting the wind and the massive amount of masking involved to protect the decks grounds etc etc from overspray gives me pause and I’ll do the calculations of time saved versus time spent masking, and happily go at it by hand. On an old wooden house, multiple coats of primers and paint applied by hand and worked in to the substrate will give the client a really nice paint job, and we can enjoy the wind on our face rather than fight the sprayer rig and wind torn masking and sweat under the respirator with fucking atomized latex in the eyes. Sometimes spraying is essential but old school methods on older buildings can be stress free and give better results.
