Portland cement takes quite long to cure. I let it sit on the ball for three days and then I carefully placed the ball upside down so the cement was at the bottom side and I removed the ball. That was easy because the plastic did not stick the the ball. Then I also removed the plastic and let the cement dry further for another 5 days.

This Portland mix is the cheapest of the concrete mixes. Demold time is 24 hours, but it will take another 2 days for the cement to reach its final color. This will dry to a light-medium grey. The directions call for at least a 3:1 ratio of sand to cement, but this is unnecessary for most cement & concrete crafts.
