How do I procure latex paint to stick on grease paint?
Answers: You can use one coat of Kilz primer. PITA, but easier than sand. Without the primer, even though it appears to be sticking now, it will not fit tightly very in good health over time and will "roll" off of the wall everytime it is bumped or scratched.
You requirement to put a primer on first. Yes, it's a lot more work, but better than sand.
You need to catch a primer to paint on the wall on top of the oil-based paint explicitly made for this very situation. It does penny-pinching one more coat of paint but I'm sure you will be fundamentally happy next to the results!
