This is incorrect. Mag Chloride is hygroscopic, meaning that it takes up and retains water. Both Mag Chloride and Calcium Chloride pull water out of the air and into your footing, keeping your footing moist without watering.
As a bonus, both Mag Chloride and Calcium Chloride also lower the freezing point of water and will keep your footing from freezing. <SNIP>
Thanks BeeHoney for accurate statements! Matter of fact, MAG (Magnesium Chloride) is much "safer" than Calcium Chloride, which is somewhat caustic on skin and eyes. We have used it for years, great results indoors and outdoors - within limits of rainy season.
People who keep saying they are watering after applying the MAG to an indoor surface are doing it wrong - when you WATER you flush the MAG down through the footing, so of course it won't work any more on the surface. Even in very arid climates, all you need is to MIST the surface - preferably at night, to give it a chance to attract the moisture.
TONS of info on all things MAG here and safety sheet MSDS HERE
I have to say this is one product I find does everything it claims to. Great stuff.
EDited to add - forgot to say our footing is a blended sand, with EquiFleece felt - fabulous, perfect footing, rain or shine, flat or jumping

Reason: didn't say what kind of footing!
