While potassium chloride is good for the environment it damages the concrete and typically costs 3 5 times more.
Calcium chloride ice melt safe concrete.
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.
Remarkable results professional strength melt is a unique formulation of calcium chloride pellets that accelerates the melting process by generating a large amount of heat on contact with snow and ice.
Being a hygroscopic compound it absorbs moisture and thereafter starts dissolving.
Melts down to 25 f.
This is a hygroscopic compound.
Proven safe when applied as directed to quality concrete surfaces melt exhibits the following properties.
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.
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.
Melt professional strength calcium chloride pellets effectively melt ice and snow on contact even at temperatures as low as 25 f.
This heat quickly melts the ice and snow thus turning it into water.
