I used joint compound many years ago. Homasote will change dimensions. I opted to screw it down rather than glue it to the plywood. Years later I have some cracks. What shows is the white from the joint compound. Only the surface was painted then covered with ballast. If I were to do it over. I’d definitely leave a slight gap and then use a black silicon or caulk to fill the joint.
