The present application is directed to an article comprising a dusty surface and a coating on the dusty surface comprising a coating polymer having a Tg less −20° C. and a method of reducing dust. In some embodiments, the polymer has a Tg less than −30° C., and in specific embodiments, the polymer has a Tg less than −45° C. The dusty surface may be, for example, crushed stone, coal, iron ore, gravel, sand or other aggregates (e.g. a roofing granule,) or a soil surface.Generally, the coating polymer comprises a polyacrylate, polyurethane, synthetic and natural rubber, silicone and other organic polymers. In specific embodiments, the coating polymer comprises an acrylic emulsion polymer.
