Mud-cracks are a phenomenon occurring when paint is applied too thickly or allowed to build up in corners during application, or when the surface is not properly repaired. Mud-cracks look like irregular cracks in a surface, resembling cracks in dried mud. New tests in acrylic exterior paints, conducted by Marschall labs (US), show that Exilva reduces the tendency for mud-cracking during drying of acrylic pigmented systems. This in turn provides the opportunity to reduce coalescent levels and related VOC levels in paint.
