How long does it take to finish watering the floor in 20 degrees?

Eight hours.

1, in the weather of 20 degrees, water can be sprayed 8 hours after the floor is poured. In general, the initial setting can be started within 2 ~ 3 hours after vibrating, and the longest setting time will not exceed 10 hour. It is ok to start curing after 8 hours.

2. When curing, the surface must be wet, but the specific operation method should also refer to the initial setting and final setting time, concrete preparation ratio and construction site temperature to judge, so as to avoid excessive hydration cracking of concrete and ensure its best strength.
