A two-coat system is a method to apply two coatings on a material’s surface. The two-coat system helps to ensure complete coating coverage of the material’s surface and enhance the overall corrosion resistance of the material.
Why do people paint two coats?
One coat of paint is more difficult to clean because paint soaks into porous surfaces.The second coat provides a type of seal and barrier, which makes it easier to wipe and clean. Durability is also better with two coats of paint.
