There are many reagents one can use to accomplish this but which one do we choose.
Urea ice melt.
Or more importantly which one do we not choose.
It melts ice down to 15 degrees fahrenheit.
As the old saying goes as an ice melt chemical it s better than nothing but not by much.
Our experience is that urea provides as much traction from not melting as it does provide melting of snow and ice.
Potassium chloride and urea.
Potassium chloride and urea are common icemelters that are often perceived as safer products to use around vegetation.
Urea does not contain chlorides so it is less corrosive and safer for use on concrete.
Potassium chloride will melt ice in temperatures down to 12 f and urea to 15 f.
Both of these products are commonly considered safe to use around vegetation as both are often added to fertilizer blends.
Urea based ice melt products are likely some of the best choices.
Calcium chloride salt pellets urea ice melt safe for concrete ice melt granular ground clear concrete edging equipment.
Calcium magnesium acetate cma this product is made from dolomitic limestone and acetic acid.
Urea is a compound with the chemical formula nh2 2co.
It is found in nature in our urine and is also.
Urea can however be very bad for your plants and lawn so it is important to use as little as possible to melt the ice around your home.
Urea has a eutectic temperature of 12 2f and a practical working temperature of around 25f.
Urea is commonly used as a fertilizer but it also used as an effective ice melt product.
Pet safe ice melt jug model 7834 10 97 10 97.
The first measure of an ice melter s effectiveness is the range of temperatures in which it can provide deicing action in a reasonable time period.
The roofmelt ice melt is designed to eliminate the roofmelt ice melt is designed to eliminate the need to climb onto roofs while melt snow.
Urea is a salt but it is a salt that your dog s body already produces and there aren t many reports of it irritating paws.
Both have environmental drawbacks as rock salt damages both flora and fauna but urea performs poorly when temperatures dip below 21 degrees fahrenheit.
Both need to be used at a slightly higher rate of application with urea melting to 15 o f and potassium chloride melting to 12 o f.
While rock salt and urea both have considerable ice melting power the decision to use one over the other is dependent upon your personal circumstances.
However over application can cause damage to vegetation.
The tablets help prevent roof damage by melting through ice dams.
The practical lowest temperature limits for these materials is defined as effective within 15 20 minutes of application and is listed next to the material.
For the sake of our watershed this article will focus on urea.
