The FAQ is approximate and product-specific. Joint layout, bead, fasteners, finish level, application, sanding, and rework mean it should not become a universal compound rule.
- Use gypsum-board face area, not floor area.
- Do not transfer the factor to a different compound.
- Confirm the current container label.
How this answer is worked out
reference pails = board face area ÷ 1,000 ft² × 2Named USG reference
| Board face area | Product | Approximate pails |
|---|---|---|
| 1,000 ft² | Sheetrock UltraLightweight All Purpose | two 4.5-gal pails |
| A ft² | same product | A ÷ 1,000 × 2 |
