PENNZSUPPRESS^® D is a dust suppressant concentrate which can be diluted with all types of water. It is typically recommended for use at a concentration of 4:1 (water:concentrate), however, this product is versatile enough for use at other dilution ratios depending on soil conditions and application methods. The 4:1 PENNZSUPPRESS^® D is pre-diluted and ready-to-use, in this popular dilution ratio.

PENNZSUPPRESS^® D is applied by spraying the prepared area to be treated with the diluted concentrate in sufficient amounts to penetrate the layer of soil to the required depth. Application is accomplished through the use of specially equipped spreader trucks designed for use with emulsified resin products.

The thickness of the PENNZSUPPRESS^® D resinous coating and depth of its penetration into soil can be readily controlled by varying the water:concentrate ratio, as well as the total volume of the diluted product per area. The versatility of this product allows the applicator to design the application to provide highest efficiency depending on prevailing dust conditions, anticipated traffic and type of soil, as well as obtaining the greatest possible economy. Some soil types may be best treated with a one-time heavy application of product, whereas others may require several light applications. As a general rule, the rate of penetration of PENNZSUPPRESS^® D is rapid in sandy soil, moderately fast in silty soil and slow in clay containing soil.

PENNZSUPPRESS^® D is used in the treatment of soils on roads, parking lots, parks, and similar high dust areas. It can also be used to suppress dust from ores and coal.  Because PENNZSUPPRESS^® D combines smaller particles into larger ones, it is useful as a soil compacting agent.

NOTE: PENNZSUPPRESS^® D and 4:1 PENNZSUPPRESS^® D dilution should be kept from freezing or boiling. If the concentrate is stored for more than one month, the product should be agitated before use.

Typically, 1/4 gallon of diluted PENNZSUPPRESS^® D per square yard is applied twice, in separate treatments, one after the other. The dilution ratio of PENNZSUPPRESS^® D concentrate to water and the frequency of treatments will vary depending upon soil conditions, porosity, anticipated traffic, etc. To aid in determining the approximate square yardage of the area to be treated, and the approximate volume of diluted PENNZSUPPRESS^® D to be applied, please refer to the chart below:
