PSA: Color psychology is a thing. The right soothing hue can work wonders for your mind and soul. You might think that only works for pale blues, but the contrast of a light and dark color — or, in this case, off-white walls with chocolate brown and deep blue accents — has a powerful effect. "The darker color grounds the room, and then the lighter runs right up to the ceiling and makes it feel higher. It creates this serene atmosphere," designer Laura Bohn told us.
A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
