The wet concrete should hold its form if you squeeze a fistful.Concrete that is too runny is easier to pour but less durable and more likely to break over time.
Add more water to your concrete mixture if the mixture is solid and crumbly., Slowly pour the concrete mix into the cast until it is completely full.
Use a metal trough to smooth the top of the concrete.You can apply a small amount of engine oil to the cast before pouring the concrete to ensure that the concrete is removed from the cast easily without damaging the sculpture. , Once the concrete is completely dry, remove the cast.
Most casts are removed after one day.
Sometimes, the sculpture is removed from the cast and the cast remains intact.
