When diluted Dust Down removes between 50% - 90% more respirable dust than water alone. Dust Down allows water to penetrate quicker into roadways meaning less run-off and evaporation. The built in humectants allows the water to be retained in the soil for longer periods of time while the unique polymer creates a microscopic film to aid in moisture entrapment.The special additive in Dust Down also retains the dust particles by a unique environmentally friendly method of making the dust “tacky”.
