We have had this question numerous times from Customers. The answer is simple, YES!!
Salt brine works faster, colder and has the added benefit of the BOOST* organic additive that ads the residual, helping to keep the salt on the pavement to help when the next storm hits.
We have found that a 80/20 blend, Brine to Boost works exceptionally well for anti-icing and pre-wetting applications down to near zero temps. When temps get in the sub-zero range, you will be time and money ahead to use the Boost product straight. It is much more effective then trying to add to the Brine/Boost mixture. This will cut done on man hours and equipment time when trying to remove pack ice in extremely cold temps.
Here are a few facts to keep in mind when mixing Brine and Boost:
Salt brine eutectic 23.3% @ 59° F
Salt brine specific gravity at 23.3% 59°F 1.179
Salt brine specific gravity at 23% 59°F – Mixed w/20% BOOST 1.279
Pounds of salt per gallon of brine 2.28 lbs @ 23.3% 59°F
You must use a hydrometer to measure the combined product. A salinometer (can go by several different names) won’t measure correctly with combined chlorides.
When mixing 80/20 blend, remember that to make 1,000 gallons, you can’t just mix up 1,000 gallons and add 200 gallons of Boost. To make a 80% – 20% mixture, you need to make 800 gallons of brine and add 200 gallons of Boost.
The second thing is that Calcium Chloride and Sodium Chloride will take a bit to combine and give you a correct reading. I suggest you wait at least a couple of hours before taking your first reading. Realistically, if the brine is mixed to 23% and you add the Boost at the correct proportions, one or two sampling’s will show you have a correctly blended product.
Good luck. Let us know how Boost works for you! Comments and suggestions are always welcome.
