Guy at the job site taught me to wet cure with burlap

Back in July, this old timer on a parking lot pour in Phoenix showed me his trick. He said soak the burlap, lay it down, then cover with plastic sheeting. I always just sprayed water and let it dry out too fast. Have you guys ever had a slab crack from bad curing?

That burlap and plastic trick works way better than just spraying water. I tried the spray method once on a small walkway and it cracked so bad it looked like a roadmap of Phoenix. Now I just stick to the wet burlap thing cause my slabs already embarrass me enough without adding cracks to the mix.

Did you ever have the burlap dry out on you overnight too, @grant_cooper?
