How to Use
Preparation
Road Surface Preparation
If the surface is permeable, smooth, firm and shaped for drainage, it's ready for application. Before applying DustGard® liquid, make sure that ruts, washboards, potholes, drainage problems, gravel segregation and hard, impervious areas have been rectified - blading can take care of most of these problems.
Pre-Watering
Before applying DustGard liquid, the road should be watered, ideally to a depth of 3 to 4 inches to break the surface tension and allow maximum penetration.
Application
Recommended application rate is 1/2 gallon per square yard, split in two 1/4 gallon per square yard applications. This will ensure deep, even penetration for good dust control and stabilization.
How much product do you need?
Multiply 300 gallons x width of road (in feet) x length (in miles) for the approximate amount for 1/2 gallon per square yard.
Example: to treat a 12-foot-wide road, 300 gallons x 12 ft x 1 mile is 3600 gallons per mile.

Compacting
As blading loosens the surface, it should be compacted with a vibratory or pneumatic roller to restore a dense, tight driving surface.
Lower Your Costs with DustGard
Loss of aggregate from traffic and wind is a constant problem for road maintenance crews. DustGard magnesium chloride road stabilizer helps counties, cities and private agencies stretch their maintenance dollars.
As the fines are lost from the road, the larger aggregate becomes loose and leads to wash boarding and reduced skid resistance. Road maintenance will be harder, requiring fresh gravel with a higher percent of fines to stabilize the road.
Studies have shown that as much as one ton of aggregate per mile is lost each year for each vehicle that passes over a road daily. This means that a road carrying 150 vehicles per day will lose 150 tons of aggregate per mile each year. Read the study from Colorado State University "Relative Effectiveness of Road Dust Suppressants", Sanders, Addo, Ariniello, and Heiden.
