Crumb coating is great to get a good base on your cake for icing later. That won’t affect what happens to your fondant. My best advise is to find the coolest, and darkest room in your house to put your cake after it’s covered in fondant. That will help it dry. If you want to paint on it, it has to get dry and have a hard surface. You could also add a very, very small amount of tylose powder to your fondant…that will help it get hard too.
