Swore I'd never pour in the rain, then a job in Galveston made me eat that
I always told my guys we wait out any rain, no exceptions, after a bad finish back in 2019. Last week we had 40 yards going down on a driveway in Galveston and a squall came in fast, so I called it and we tarped up. The homeowner's buddy, a retired finisher named Ray, showed up and said to pull the tarp and finish it wet with a bit more retarder in the mix, so we did. Turned out dead flat with no scaling, and now I'm second guessing my whole rule. Anyone here actually pour through light rain on purpose?

Ray's move makes sense when you break it down. The rain adds water to your mix anyway, so bumping the retarder just buys you time to keep working it instead of fighting a set. Guys up north do this all the time with light drizzle and wind screens, they just watch the slump like a hawk. Your 2019 rule probably saved you from a pour where the rain was heavy enough to wash the cream off, but a Galveston squall is a whole different animal. Might be worth splitting the rule into light rain and real rain instead of throwing it out.
