Just wanted to double check before I placed order. Note: I already own a udm pro SE and the UNVR, just added to the cart for the purpose of showing the full set up. Any suggestions is appreciated, thanks!

Not sure if it's good to just sand, primer and paint or will I need to do another mud layer? Not looking for a perfectly smooth wall, but not complete garbage either. Open to any thoughts and suggestions, TIA.
