What this calculator assumes
- Joint compound is figured at one 4.5 gallon bucket per 475 sq ft of board for a full three coat finish. A level 5 finish uses more.
- Tape is figured at 380 linear feet per 1000 sq ft of board, screws at 32 per sheet for 16 inch on center framing.
- Longer sheets mean fewer butt joints, which is less taping and a flatter wall. Use 12 footers where they will fit through the door.
