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.
Urea ice melt concrete.
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.
On the other hand urea will not chemically damage concrete however it contains nitrogen which breaks down to ammonia and is quite toxic to aquatic life.
Urea has a eutectic temperature of 12 2f and a practical working temperature of around 25f.
Our experience is that urea provides as much traction from not melting as it does provide melting of snow and ice.
The heat that it gives off as it dissolves help melt ice easily.
As the old saying goes as an ice melt chemical it s better than nothing but not by much.
It has little effect on plants and concrete but its performance.
Best rock salt alternative.
Potassium chloride and urea are common icemelters that are often perceived as safer products to use around vegetation.
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.
This is a traditional ice melt which melts ice down to temperatures of 25 degrees fahrenheit.
A great choice to consider for your concrete is a fertilizer based ice melter such as xynyth manufacturing s mountain organic natural ice melter รค which is potassium based.
Made with urea one of the least harmful salts and least likely to irritate your pup s feet or pose an ingestion danger.
It is less damaging to concrete and safer on plants.
Urea does not contain chlorides so it is less corrosive and safer for use on concrete.
The time released formula claims to last 3x longer than standard ice melts.
Calcium magnesium acetate cma.
Urea is commonly used as a fertilizer but it also used as an effective ice melt product.
It melts ice down to 15 degrees.
Calcium chloride salt pellets urea ice melt safe for concrete ice melt granular ground clear concrete edging equipment.
How doers get more done.
Longest lasting ice melt.
Commonly used as a fertilizer it is also an effective ice melter.
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.
A great choice to consider for your concrete is a fertilizer based ice melter such as xynyth manufacturing s mountain organic natural ice melter which is potassium based.
Both have environmental drawbacks as rock salt damages both flora and fauna but urea performs poorly when temperatures dip below 21 degrees fahrenheit.
It is made from dolomitic limestone and acetic acid the main compound in vinegar.
