Those round silver cans are always conveniently labeled to let you know when a paint is meant to be used inside or outside of your home. The distinction is helpful, but what really is the difference? As you look for exterior painting companies in Tempe, AZ, here's why you should adhere to using different types of paint according to their labels. The Basic Science of Paint How does paint work, exactly? Any kind of pant contains pigments for color, solvents that liquidize it, additives to preserve it on the shelf, and resins that essentially keep the paint glued to the wall. Water is the solvent in latex paint, while mineral spirits are the liquid of choice for oil-based paints. Paint dries on your wall as a result of that solvent evaporating, leaving behind all those other ingredients. Interior or Exterior The biggest difference between these two different types of paint is the type of resin that is chosen for each of them. The resin, or glue, of the paint is meant to function differently on outdoor walls by helping paint survive temperature shifts and exposure to moisture. Exterior paint resin makes the paint tougher against peeling and chipping, and keeps sunlight exposure from fading the color too quickly. Resins don not need to be as durable for interior paints. Other Factors The resins used in exterior paints give off stronger fumes as they dry than those used in interior resins. The health factor is also a prime reason to stick to the labels. It is that simple! Whether you're looking at interior or exterior painting companies in Tempe, AZ, you should ask a painting professional their opinion of different paints, resins, and colors to see what color solutions are the best fit for your home.
