Good ice melt choices for concrete are calcium chloride and magnesium chloride.
Calcium chloride on concrete for ice melt.
A calcium chloride ice melt melts ice and snow down to temperatures of 25 f safe to use on concrete and vegetation when used correctly.
The dissolving process is exothermic and generates heat of up to 60 degrees celsius.
So it absorbs water and then generates heat as it dissolves up to 140 f.
This heat quickly melts the ice and snow thus turning it into water.
Melts down to 25 f.
Melts snow ice 4x faster.
Calcium chloride works 4x faster than rock salt by generating exothermic heat that instantly melts even the thickest snow ice with maximum safety and little effort.
Experts agree that calcium chloride is the best ice melt for concrete surfaces.
Melt professional strength calcium chloride pellets effectively melt ice and snow on contact even at temperatures as low as 25 f.
This is a hygroscopic compound.
While opinions are not always the same most experts agree that calcium chloride is the best product for those seeking an ice melt that is safe for concrete.
No other ice melter out performs calcium chloride pellets.
While potassium chloride is good for the environment it damages the concrete and typically costs 3 5 times more.
Another good de icer is cma or calcium magnesium acetate which doesn t wash away as easily as the others and has a lower environmental impact.
