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.

| 8 | 4,694 | 2,346 | 1.88 |

| 16 | 9,386 | 4,694 | 0.94 |
| 20 | 11,372 | 5,866 | 0.75 |
Compacting:
As blading loosens the surface, it should be compacted with a vibratory or pneumatic roller to restore a dense, tight driving surface.
