What it is

We start with plain rock salt and coat every grain with two things:

A liquid deicer, such as magnesium chloride, calcium chloride or an agricultural (beet-juice style) blend.
A dye, usually blue or green, so the treated salt is easy to see on snow, ice and pavement.

The blend can be adjusted to the job: a colder-rated liquid for January cold snaps, or a lighter treatment for routine events.

How it's made

Start with clean, dry rock salt from the stockpile.
Meter the liquid and dye. The liquid deicer and colorant are mixed and measured to a set rate per ton.
Spray and blend. The salt runs through a mixer, auger or conveyor spray bar, so the liquid and dye coat the grains evenly instead of soaking one corner of the pile.
Let it cure. The coated salt sits briefly so the liquid soaks into the surface of each grain.
Store covered, load to order. Treated salt is stockpiled under cover and loaded or delivered like regular bulk salt.

Exact liquids, rates and colors vary by product and season. Your quote lists the blend.

Why treat it

Works colder

Plain rock salt bogs down below about 15°F. The liquid coating helps treated salt keep working at lower temperatures. How much lower depends on the liquid used.

Starts faster

Salt has to turn into brine before it melts. Treated salt brings its own liquid, so it gets going sooner.

Bounces less

Damp-coated grains stick where they land instead of skipping off the lot into the grass, so more of what you pay for stays on the pavement.

Uses less

Faster, colder melting with less scatter means many crews can cut application rates. Calibrate and adjust to what you see on the pavement.

Why color it

Proof of service

Your client can see the lot and walks were treated. A timestamped photo of colored salt on a walk is strong documentation if a slip-and-fall or insurance claim comes in later.

No over-application

Operators can see coverage as they spread, so they stop doubling back over treated areas. That saves material and spares concrete and landscaping.

No missed spots

Gaps are easy to see, so missed walks and corners get caught before someone falls.

Dye can track indoors on boots. Use entrance mats on light floors. Keep application records (date, time, location, material, rate) alongside your photos.

Questions

Is colored salt just regular salt with dye?

No. Ours is plain rock salt coated with a liquid deicer and a dye. The liquid makes it work better. The dye makes it visible.

Does the color stain concrete?

The dye usually fades with melt, traffic and sun. They can track indoors on boots, so use entrance mats on light floors.

Can I pick the liquid or the color?

Ask. Blends and colors depend on what's in stock and the season. Your quote lists the blend.
