  • Spread ice melt thinly: it needs only enough to start a brine, and extra salt just washes into the soil and the water. Clear the snow first, and spread before a storm if you can, since that stops the ice bonding to the pavement. Rock salt (sodium chloride) stops working somewhere around 15°F, and calcium chloride keeps working to about −25°F. These are typical rates for a home; where the label gives a rate, use it.

Before you buy: round up to whole packs, check the size printed on the label, and add a little spare. Your supplier has the final say.

A public sidewalk in front of the house

Many towns require the owner to clear the public sidewalk within a set time after the snow stops, so check your local rules. A 5 × 50 ft stretch is 250 sq ft: 1.25 lb at the normal rate and 2 lb when it is packed snow or thick ice.

Shovel to the pavement first, then spread a thin band along the middle of the walk rather than the full width, so it does not wash into the grass strip by the curb. A long, narrow walk like this is quicker to treat with a hand spreader than by scattering, and it uses less.

How much salt for a sidewalk?

For 250 sq ft of sidewalk, about 1.25 lb a treatment at the normal rate and 2 lb on packed snow or thick ice. A thin band down the middle is often enough.

Will ice melt kill the grass by the sidewalk?

Too much of it can. Salt that is swept or washed onto the grass strip builds up over a winter, so spread thinly and keep it to the walk.
