Our Ice Melter works from the moment you apply it to the ice and snow that has accumulated on your sidewalks, parking lots and high-traffic areas. It exothermic action melts ice, preventing dangerous refreezing and works fastest, because they attract moisture, releasing heat as they work.It keeps working when all other ice melters stop because of dropping temperatures. It will work in temperatures a low as -25ºF. It leaves no messy residue or powdery coating behind that can be tracked onto the floors and carpets of your home or office building, which means fewer clean-ups, lower maintenance costs and a better looking winter building.
