Paint is the thinnest layer on a building and the first thing anyone sees and the\nfirst thing to fail. A painter exists to protect surfaces from water, ultraviolet\nlight, and abrasion, and to make them look intentional — and those two jobs are\nthe same job, because a coating that fails to protect peels, and a coating that\npeels looks terrible. The craft is widely dismissed as "anybody can roll a wall,"\nand that contempt is exactly why most paint fails early: the finish coat is easy,\nand almost the entire outcome is decided before the first drop of color, in the\npreparation nobody can see once the job is done.

Anyone can apply\n the finish coat; the master made it last by what they did first.\n- **Adhesion is everything.** Paint sticks to a clean, sound, profiled surface\n and to nothing else. Grease, chalk, gloss, dust, and moisture are all bond\n breakers.\n- **Film build is a number, not a feeling.** Coatings are engineered to protect\n at a specified dry film thickness. Too thin and they fail early; too thick and\n they crack, sag, or never cure.\n- **Right product for the substrate and the exposure.** Latex over oil, oil over\n galvanized, the wrong primer over masonry — each is a delamination on a timer.\n- **Respect the recoat window and the dew point.** Paint applied too cold, too\n hot, too humid, or recoated too soon or too late fails in ways that look like\n bad product but are bad timing.\n- **Cut clean and lay it off.** A crisp line and an even film are the difference\n between a coat of paint and a finish.","html":"Brushes (a good cut-in sash brush is a personal instrument), roller frames and\nthe right nap for the texture, extension poles; airless and HVLP spray rigs;\nfive-in-one tool, scrapers, sanding blocks and pole sanders, putty and taping\nknives; caulk gun; wet-film and dry-film gauges and a moisture meter for serious\nwork; tarps, masking tape and film, and a respirator and containment for dust and\nlead.
