Brine questions

    So, I made some brine and used it for our first snow. I was impressed with the outcome and will continue to use as a pre-treatment (large lot-seasonal contract)

    My curiosity has the best of me and I can't find a good answer. Has anyone ever tried to use brine as a de-icer? I know it won't work much below 20 degrees but why wouldn't it work down to 20? What if I i used 10% LCC to 90% brine? I'm not a scientist by any means but would like some opinions.

    Thanks

    Add 20% Ice B Gone Magic to it and reduce it to -5 degrees... and you will need less... Liquids will work as deicer but you need to cover more area with truck as compared to granular which throws further.

    Your best result is to get a hydrometer to measure your salt content to water. You can buy them online for 20 - 50 bucks. Optimum is 88.3% salt content which will allow the brine freeze point to -6 degrees. Mixing brine is a lot like mixing antifreeze. To much water will lower the freeze point & to much salt will have the same affect. We use brine for pre-treating & pre-wetting system applied to salt at the spreader.

    88.3% ??? I think your numbers are off.

    I am making the brine to a 23% solution, I get why it needs to be at that. I'm just wondering if it can be used as a de-icer as well?

    Ok had to get my chart.

    Salometer degrees 88.3
    Percent of sodium chloride by weight 23.3
    Specific gravity 1.179

    = -6 degree freeze pointThumbs Up
    Sorry for the confusion

    To op. 90/10 is all I use and usually post plow. It works very well especially after a fluffy snow event. Not so good on thick ice or wet snows.

    anti-icing vs deicing

    usually you would use twice the amount of product to deice than anti-ice. but the theory of it was to use a straight shooter spray tip that would punch through the ice layer to the pavement below. once through the pavement it would start breaking the bond of the ice to the pavement. Never heard of a lot of people using it this way especially if they anti-iced before the storm. also just like treating salt any additive you add would enhance the salt brine as well

    We use it all the time as a de-icer after plowing. In the instance of freezing rain or say frozen low spots, it still works but kind of pointless at that point. Our solution is the same as yours and we still use it well past zero F. Like someone said, you have to use a bit more but again it will work just fine.
