Walked past a pour on 5th in Boise, and that plastic sheet changed how I finish in the cold
I saw a crew curing a slab under a plastic sheet last Tuesday, and I always thought that was just for looks. Turns out keeping the water in the mix for 7 days instead of 3 gives you way fewer cracks, and I saw it with my own eyes on their slab. Anyone here still skip the sheet when it drops below 40?
