I am going to be pouring a footing and 6" wall on one part of my property that has no access to water. Temps here have been around 100 degrees the past few days and I know these are less than ideal conditions for curing. I was wondering what you folks would suggest here. A spray-on curing compound, or burlap and plastic sheets. Which is gonna be cheaper and which is gonna be the most effective? Also, has anyone ever tried using waste motor oil as a release agent on plywood forms? Thanks!
