Paints made with PolySept ® will help keep your walls looking cleaner and reduce the risk of fading. Outdoor applications are especially important: Weather can cause paint to crack or fade quickly in some areas and show signs of fungal growth on others. Kitchens and bathrooms are constantly up against different temperatures and humidity, but with PolySept ® added in the manufacturing process of paints, surfaces will continue to look good and clean up easily.
