CapSure Mist™ Dust Control for Unpaved Roads
Capture fine dust. Stabilize the surface. Reduce repeat watering.
CapSure Mist™ is a mist-applied dust suppressant designed to capture and hold fine particles (“fines”) so they don’t become airborne under traffic and wind. It helps reduce visibility hazards, improves site cleanliness, and can lower grading and maintenance frequency compared to water-only dust control.
CapSure Mist™ Dust Control for Unpaved Roads
Unpaved roads depend on fine particles to help bind the surface together. When those fines are lost, the surface starts to ravel, dust levels rise, and maintenance costs increase.
CapSure Mist™ is designed to:
Agglomerate fine dust particles (pull them together)
Bind surface particles to each other and to larger aggregates
Increase surface density and stability
Reduce airborne dust caused by tires, traffic turbulence, and wind
How it works
CapSure Mist™ uses zwitterionic technology to promote particle capture and cohesion at the surface.
In practical terms, the mist helps create a more stable surface by:
Encouraging fines to clump and settle instead of lifting into the air
Improving the “lock-up” of surface materials, reducing loose dust on top
Supporting longer-lasting dust control than water in many operating conditions
Technical note: In some embodiments, the formulation can have a surface tension of less than 30 dynes/cm.
Why not water?
Water can temporarily knock down dust—but it often fails quickly in real site conditions.
Water limitations
-
Evaporates fast (sun, wind, low humidity)
-
Larger droplets can skip/repel fine particles (the “bounce effect”)
-
Requires frequent re-application, increasing labor, equipment time, and water demand
CapSure Mist™ advantage
-
Low surface tension produces fine droplets that better contact and capture dust-sized particles
-
Designed to retain performance longer than water because it doesn’t rely on evaporation-based moisture to work
-
Can reduce repeated watering cycles on many sites (results depend on traffic, surface, and climate)
Where CapSure Mist™ is a strong fit
CapSure Mist™ is commonly suited for:
Haul roads, service roads, and industrial access roads
Construction routes and staging areas
Remote sites where water delivery is costly
Dust-sensitive areas (facilities, camps, public interfaces)
Operations aiming to reduce dust without paving
What affects performance (the dust “drivers”)
To get the best results, your program should account for:
Vehicle speed and traffic volume
Truck percentage and vehicle weight
Surface gradation and fines content
Surface compaction and road condition
Climate variables (humidity, rainfall, evaporation rate)
Application guidance
CapSure Mist™ performance depends on road prep + correct application rate + reapplication timing.
1) Prepare the road surface (most important step)
Before applying, it’s recommended to:
-
Repair unstable areas (soft spots, failed subgrade sections)
-
Establish drainage (crown and crossfall)
-
Regrade to remove ruts, potholes, and erosion channels
-
Remove poorly graded “boney” material where possible
-
Compact the surface (as appropriate for your site and sequence)
2) Apply for proper penetration
Maximum benefit is typically achieved when the mist penetrates roughly:
10–20 mm (0.38–0.75 in)
Good penetration helps reduce loss from surface wear, improves cohesion, and supports longer service life.
3) Set rate and frequency for your conditions
Use product guidance plus site realities—application rate and frequency typically increase when you have:
-
High speeds, high volumes, and heavy truck traffic
-
Low humidity / high evaporation conditions
-
Low fines content (often <10% passing 75 µm / No. 200 sieve)
-
Loose surfaces or poor blading
4) Maintain and reapply as needed
All dust suppressants have a finite service life. Reapply when dust rises above acceptable levels. Follow-up applications can often be lighter than the initial treatment, depending on surface condition and traffic.
Environmental and operational considerations
A responsible dust program considers:
Water quality and drainage pathways
Adjacent aquatic habitat and vegetation
Overspray control and application practices
Site-specific regulations or permit requirements
(Always follow your site’s environmental plan and SDS/handling guidance.)
