Hardest most durable paint depends on category, but generally two-part catalyzed coatings are hardest and most durable. For industrial and floor applications, two-part epoxy paint is among hardest, chemical resistant, and extremely durable for garage floors, industrial floors, and marine, curing to very hard film requiring grinding to remove. For automotive and metal, two-part polyurethane and urethane paints, especially 2K urethane with hardener, are hardest and most durable, providing excellent gloss, UV, chemical, and scratch resistance, lasting many years. For house trim and cabinets, oil-based alkyd enamel and waterborne urethane alkyd enamel cure harder than regular latex, with urethane alkyd being hardest among trim paints. Powder coating, which is baked on, is extremely hard and durable for metal. For walls, high-quality 100 percent acrylic enamel in semi-gloss is most durable among wall paints for washability. So overall hardest most durable paints are two-part epoxy for floors, 2K urethane for cars and metal, and urethane alkyd enamel for cabinets, which are catalyzed and chemically cure to hardest films, far harder than regular latex wall paint.
