Do you put salt down before or after it snows?
Rock salt is meant to be put down before snow falls, and keeps it from sticking to the surface, says Nichols. “But most people shovel, get it clear, then put down the salt. If you salt and then get snow on top it can turn to mush underneath and then it gets hard to shovel.”
Should I salt my driveway before freezing rain?
The best time to treat the ground is before snowfall begins. Treating areas before snow (and freezing rain/ice) begins can help prevent ice from forming and prevent snow from settling. Because salt has a lower freezing point than water, it reduces the opportunities for moisture to freeze on treated surfaces.
When should I put salt down on my driveway?

What temp does salt stop working?
At a temperature of 30 degrees (F), one pound of salt (sodium chloride) will melt 46 pounds of ice. But, as the temperature drops, salt’s effectiveness slows to the point that when you get down near 10 degrees (F) and below, salt is barely working.Is salting your driveway bad?

It starts to melt as quickly as straight calcium, but lasts as long as other sodium/potash blends. Below is a graph of melt volumes produced in 20 minutes at -10°C (14°F). An ice melter’s granule size and surface area both affect the melting process.
Is salt bad for sidewalk?
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.

What temp is rock salt good to?
In the highway deicing world the practical working temperature of salt is generally considered to be above 15 0F or even 20 0F. There are two reasons for this. One is that the amount of ice that can be melted per pound of salt (or any other deicer) decreases with temperature.
At what temperature does salt evaporate?
