Wrote off dry shake hardener after 12 years, then a slab in Reno humbled me
Spent two days fighting a 4,000 sq ft warehouse pour in Reno last week where the surface kept dusting no matter what I did, and a guy half my age showed me that sprinkling hardener at the right window instead of right after screeding fixed the whole thing, so now I'm rethinking how I've done it since 2012.
