Hey folks,

My driveway is fairly long and dusty. I'd like to put down some calcium
chloride to help hold the fines together and keep the driveway in better
shape, as they do with the local ( SE MI) roads here.

I can buy the stuff in chip form in50 lb bags. the county puts down the
stuff on the roads in liquid form though.
I was thinking I'd buy a bag or 2 and mix it with water and then put it in a
sprayer or pour it out on the driveway.

anyone done something like this before?
I've read that the liquid is often a 35% solution, how can I come close to
that same percentage when mixing my own?
any idea's on how to apply it? I've got a dinky weed sprayer, but that
would take forever....

thanks for you ideas

Dave

In fact, calcium chloride is extremely hygroscopic (attractive to
water
molecules). That's _why_ it's so often used to keep down dust- it
attracts atmospheric moisture, thus dampening surface.

Around here, highway crews have used plain flakes for many years,
to keep down project dust. In short oder, it's wet.

You'll find that it's hard to keep calcium chloride _dry_.

HTH,
