When and When Not to Use Dust Palliative
By Brooks Morse // 2020-08-03
The main purpose of a dust palliative is to temporarily prevent erosion and provide temporary stabilization for dust. Dust palliatives are often used in the construction industry and can be used in a variety of climates such as the desert here in Arizona. Proper research should be done to determine the correct palliative for your climate. Due to the lack of rain in Arizona, the soil is very dry and often becomes airborne once the material on a construction site is disturbed. County regulators suggest dust palliatives on high traffic unpaved roads within a construction site, as it is proven to minimize dust if applied correctly. One example of an incorrect application is applying a dust palliative immediately before a rain event. Palliatives need time to cure to the soil. Several factors must be considered when identifying the time to apply such as weather, temperature, site activity and many others. You must follow the manufacturer’s recommendation for application rates. When a palliative is applied correctly it can hold effectively even during strong winds. Depending on weather such as rain the site may need another application over time.
