First Standard for Dark, Saturated Colors This tough, engineered thermoplastic polymer promotes excellent weatherability, color retention and durability thanks to carbon-fluorine bonds that do not break down under exposure to the elements. Coating systems formulated with polyvinylidene fluoride (PVDF) resin, on the other hand, deliver longer-term performance-more than 20 years. Chalking isn’t always easy to see on white or off-white coatings, but it is quite obvious on darker colors as it changes their hue.Ĭhalking is a common problem, even with high-performance urethanes and acrylic latex paints, and especially in climates such as South Florida and Arizona, where their typical lifespan is about five years. A chalked surface also becomes a food source for mold and mildew growth and makes conditions ripe for dirt collection. Chalking, caused by a physical breakdown of the coating’s polymer, creates a white, powdery residue that compromises the coating’s appearance and eventually gets washed off into the ground, where it can serve as a pollutant. Even high-performance paints can quickly chalk, fade, and degrade, especially those with deep colors and bright hues. When Coatings FadeĬommodity, off-the-shelf paints may come with a lower initial price tag, but they also come with a shorter lifespan.
Now they have a new tool-the Society for Protective Coatings (SSPC) Paint 47 Standard-to help them determine how well the field-applied coatings they choose will stand the test of time. Therefore, building owners, architects, and project specifiers want exterior coatings to provide long-term protection. They are also an expensive maintenance headache and can pose a threat to the environment. At that point they likely would need to be replaced-a costly, time-consuming and disruptive endeavor that adds to our globe’s landfilled waste stream.įaded and degraded building facade materials are more than just an eyesore.
Without protective coatings, facade materials can become exposed to the elements, eventually degrading to the point of structural instability. The right coating, when expertly applied, delivers a curb appeal that reflects the occupants’ tastes and the building’s purpose think bold, primary colors for a school, softer sand-and-sky colors for a coastal home, or sleek, metallic hues for a high-tech office.īeyond aesthetics, exterior paints and coatings protect facade materials from damage caused by UV rays, rain, humidity, windborne particles, chemicals, mold, mildew, and other environmental conditions. Frequent repainting-needed every five to 10 years when latex- or urethane-based formulas are used-is costly and disruptive.Įxterior paints and coatings play both decorative and protective roles on a building’s facade.Off-the-shelf paints may come with a lower initial price tag, but they also come with a shorter lifespan.Exterior paints and coatings protect facade materials from damage caused by UV rays, chemicals, mold, and other environmental and weather conditions.
