The joint compound is an adhesive filler that can fill gaps, uneven surfaces, and cement boards. If you have any of these issues, you can use the joint compounds. But the thing is, the joint compound is different from the drywall.
So, you cannot directly paint over the joint compounds as you did to the drywall. But that doesn’t mean you can’t paint the joint compounds. Of course, you can, but the process is different.
You must give a prime coat over the compounds; you can apply the paint when the prime is dried.
