First time using BM Command

The closest dealer to me selling Centurion just closed down, I can order it but I was experimenting with some coatings I can get locally. I chose BM Command based on what people say about the durability but I'm not impressed. I'm painting a couple cabinet doors in a dark grey, first coat went on an hour ago and it still feels very soft to the touch. I can dent it easily with a fingernail and scratch it off. How long do I have to let it cure? Thanks
