Dustex is a uniquely formulated lignosulphonate-based binder and gravel preserver suitable for binding both fine and coarse particles. Dustex is also suitable for spray-on applications to the surface of areas requiring short or medium term dust suppression.

• Liquid: 1-2%
• Powder: 0.5-1%

• Liquid: 1.0-1.5 kg/m²
• Powder: 0.5-0.8 kg/m²

• Reduced gravel loss and dust levels and road maintenance
• Suitable for use with a variety of materials with compositions and characteristics
• Easy to apply, no specialised equipment required
• Roads can be trafficked immediately
• Environmentally friendly, non-toxic and non-hazardous

• Dilute the required Dustex with the water in the water bowser

• Fill the bowser with one-third water; then add the required Dustex. Circulate the water during this process if possible. Once mixed, fill the bowser with water.

• Rip the road to 150 mm and break large clods to maximum 50 mm
• Calculate the approximate volume of water required to reach OMC and add 85% of the required product application rate to this quantity of water
• Apply the solution onto the prepared surface in 2 to 4 applications, mixing thoroughly between applications
• Shape to required camber and compact with pneumatic or vibratory roller to required density
• Apply remaining 15% product to the road surface while still damp

• For spray-on applications, the road surface should be well compacted, density >93%, firm and free of excess loose material and with sufficient camber to allow for proper drainage
• Apply the product in multiple applications using a 10-15% solution of product with water
• Avoid run-off and pooling
