Salt Spreaders: 5 Fast Facts

Fact #1. People apply salt to roads, sidewalks, and other types of pavement to combat snow and ice, thereby making the surfaces less slippery. The chemical process is actually rather simple. When water freezes, the loose molecules within position themselves in a more compact, structured way. Salt disrupts this process by acting as an impurity in the water. This disrupts its ability to form ice.
Fact #2. The addition of salt decreases the temperature at which water will freeze. The more salt you dissolve into the water, the lower its freezing point becomes. For example, instead of freezing at 32 degrees Fahrenheit, the salted solution may not freeze until the temperature reaches 22 degrees Fahrenheit.
Fact #3. Whatever salt compound you choose, you're spreading it to accomplish one of two things: de-icing or anti-icing. When you de-ice a surface, you're eliminating snow or ice that already exists. When you anti-ice, you're taking a more preventative approach. You want the solution to remain on the surface for a certain period of time to continuously delay the formation of ice or frost.
Fact #4. You should ask yourself where you'll be using your salt spreader. If the answer is limited to your own property, you don't need to worry about hopper and tailgate models. If you only need to de-ice a little patio or walkway, just go with a handheld model and call it a day.
Fact #5. To implement an effective de-icing program, safety and efficiency are key. If you're working with a small unit at home, you can begin by using a shovel or snow blower to get rid of any snow that has accumulated. When you do begin the de-icing process, make sure to wear protective gloves. Ideally, you should keep kids and pets inside as you apply the solution.
