I have a damp closet below ground level. Instead of installing sheet rock I will be installing 3×5 sheets of 1/2″ Hardi Backer Board on the walls.
Can I tape and paint the Hardi board? I am using it instead of sheet rock so it wont retain dampness and I will not be installing tile only paint. Also, do you think taping compound would work?

For the taping use fiberglass drywall tape and a setting type of joint compound. The setting compound is a powdered drywall compound available in bags. You can choose different setting times, from 20 minutes to an hour or more. I like the 45 minute type. Go ahead and tape and finish as normal.
The backer board and joint compound will need priming before painting. Use an acrylic primer.
