Good ice melt choices for concrete are calcium chloride and magnesium chloride.
Best de icer for stamped concrete.
Potassium chloride will only work if the air temperature is about 15ºf.
Calcium chloride these round white pellets when used in a high enough concentration may chemically attack concrete.
This will also eliminate the need to shovel these areas as the snow can be left to melt in the springtime.
It is 100 percent calcium magnesium acetate safe for new concrete and it does work.
It will work in temperatures as cold as 13ºf.
Cma is calcium magnesium acetate and it is the product of choice and most often recommended for new concrete structural concrete as found in elevated walkways and parking garages and in places with salt prohibitions.
When you are looking for the best concrete deicer you have to take into consideration your environment temperatures and the corrosive properties of the melting agent.
Magnesium chloride the best safest and newest deicing slat on the market.
Calcium chloride will melt snow and ice on concrete in temperatures as low as 25 degrees fahrenheit.
The dissolving process is exothermic and generates heat of up to 60 degrees celsius.
While potassium chloride is good for the environment it damages the concrete and typically costs 3 5 times more.
Homeowners with stamped concrete should avoid salt based ice melts at all cost.
For areas that will be in use during the winter you need to choose a salt free ice melt such as safe paw ice melter to prevent discoloration.
If we re talking about pure melting power then the best deicer for concrete is calcium chloride.
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.
Being a hygroscopic compound it absorbs moisture and thereafter starts dissolving.
