For 472 sq ft of drywall finished to a standard three-coat Level 4, plan on about 4.7 gal of joint compound — 2 × 4.5 gal (17.0 L) containers — and 1 roll of paper tape.
Joint compound to buy
2 × 4.5 gal (17.0 L)

Buy the 4.5 gal size rather than several small tubs; an opened pail keeps for the next coat if the lid is pressed back on tight.
