Salting your driveway? Here's when you should actually be doing it for maximum melt

If you’ve recently had heavy snowfall and are battling icy conditions, you’re probably faced with the task of removing ice from your driveway. Although there are many de-icing methods, salt is the most common and quickest way to de-ice a driveway, making the area safe.

But while we tend to sprinkle salt all over icy surfaces, waiting for it to get to work, it turns out that we’ve been doing it all wrong. According to experts, there is an ideal time and right way to apply salt on our driveways — and it’s not when we think.

Here’s what you need to know before you get outdoors this winter.

When is the best time to apply salt to our driveways?

The ideal time to apply salt to your driveway is actually before the first snow and ice appear, rather than waiting until it has already formed. Essentially, this form of pre-treating the driveway will make it less difficult for snow and ice to stick to the ground, resulting in hard layers of ice.

Of course, to get the best results and ensure your de-icing efforts are as effective, you’ll need to monitor weather reports beforehand. This will allow you to stay ahead of icy conditions.

How does salt work to melt ice?

Rock salt is typically the most cost-effective and efficient de-icer around. It works by lowering water's freezing point, which allows ice to melt even when the temperature is below 32 degrees Fahrenheit, the normal freezing point of water.

Other types of effective ice melt include calcium chloride, which comes in the form of non-staining, blend pellets, and magnesium chloride, which can be sprinkled over driveways and icy paths.

Additionally, while table salt can be used to de-ice your driveway this winter, it won't be as effective as commercial salts, particularly once temperatures fall below freezing.

How to apply salt to driveways

The first step should be to clear loose snow, leaves, or debris from the driveway with a shovel or a large outdoor broom. Next, apply a thin, even layer using a garden shovel, spade, or a container. For an average-sized driveway, it’s recommended to only use about 15oz of salt. Pay close attention to problem areas where there tends to be a buildup and reapply if necessary.

Just take note of these surprising effects of using too much de-icing salt on your driveway and always wear suitable shoes and clothing when venturing out on icy surfaces.
