In hot climates where set up times are very fast you may need extra work time to get things done. Borderline's D-cell is a powder-form admixture that when added to your mix will extend the curing process of your curb. The recommeded amount is a 2oz scoop per mix. The amount of heat, humidity, and conditions will dicate if you need a larger dose. If you can get an extra five minutes that could mean everything. We do not recommend more than 4 oz.
A 10lb bucket will get you approx 70 mixes using a 2oz scoop.
