Any input on plaster and filling in colder temps? We are in Austin and are scheduled for plaster next week (Feb. 8). Though the ice we're currently experiencing will be thawed by then, nighttime lows are forecasted in the mid- to upper-30s though daytime highs in the high-50s/low-60s. Should we be holding off a bit longer on plaster and filling the pool due to this kind of weather? There's really no rush as--even with the heater--I don't see us getting in the pool this month! Would appreciate any feedback/experience on this topic.
