WebJan 18, 2016 · This is true for ethylene (?) glycol, the stuff for cars, and I suspect it applies to propylene, too. Your best protection (lowest freeze point) is w/ a 67% glycol/33% water mix. Not that your slab is going to get to -70 F or anything, but just for general knowledge I figured I'd throw in a car-related fact. Fair? http://en.libyan-cna.net/search-eopxyz/Freezing-Point-Meterfor-Glycol-Antifreeze-Coolant-and-Battery-AcidRefractometer-60078/
