I just applied some Quikrete brand Quick-Setting Cement (No. 1240) to fill a 16x16x1.5" hole in my basement floor.
Regarding curing, the datasheet just says
"Efficient damp curing is required for 48 hours"
I googled "Efficient damp curing" and all the results were the same datasheet, so this doesn't seem to be a standard industry term. Can anyone clarify what it means?
For now, I've just covered it with a plastic sheet held up off the fresh concrete by a 2x4 straddling a couple of bricks on either side of the new concrete. Weighed the sheet down around the perimeter so air can't flow through. Turned off the basement dehumidifier and central AC for the night so it doesn't get too dry. It's about 22'C (72F) and about 50% humidity in the basement.
Is that sufficient or should I spray or mist it with more water in the morning and remainder of the 48 hours period?
