Different paints come with different properties, as they are manufactured for different purposes. Exterior paint is formulated to handle mildew and fading. Interior paint, on the other hand, is made to allow cleaning and resist staining. Exterior paint is made to survive inclement weather while resisting mold, mildew, fading, cracking, chipping, and more. On the other hand, interior paint is made to resist stains and be scrubbed clean without being damaged. Interior paint is also made with chemicals that are safer for breathing.
