Unpopular opinion: spray-on cure is better than wet curing for flatwork

I know everyone swears by wet curing with burlap and hose water, but I switched to spray-on membrane cure for a 4,000 sq ft warehouse slab in Austin last summer. The humidity was all over the place and we couldn't keep burlap wet consistently. Spray-on gave us a uniform seal that held moisture for 7 full days. No cracking, no dusting, and we finished right on schedule. Has anyone else tried it on a big pour and seen better results than the old method?

You said it held moisture for 7 full days. What was the temperature range during that time? I'm wondering if it still works as good when it's pushing 100 degrees.

Man oh man, that's the real question right there. I was testing it at like 85-90 degrees mostly, and it held up fine, but I gotta say when it hit 100+ I noticed it started drying out way faster, maybe 4 or 5 days tops. I think the heat just sucks the moisture right out no matter what you put on it. If you're in a real scorcher you might have to reapply sooner or use a thicker layer.
