DustGard® is liquid magnesium chloride produced from naturally occurring minerals. It is hygroscopic (attracts moisture) to provide maximum control of dust. Applying of DustGard® will create compact, smooth road surfaces.
DustGard® is environmentally friendly. It will control dust and stabilize the soil.
To apply DustGard®, special equipment is required. The amount of DustGard® Liquid applied on gravel roads must be regulated by trucks equipped with on-board computers.
Before applying DustGard®, the road surface should be watered to a depth of 1 to 2 inches. This will break the road surface tension and allow greater penetration.
