🪣 Drywall mud coverage: One gallon covers ~80-120 sq ft per coat (tape coat uses less). All-purpose mud for embedding tape; lightweight for top coats. Setting-type mud (hot mud) for fast drying.

💡 Pro tip: Estimate 1 gallon per 100 sq ft per coat as a general rule. Buy all-purpose for first coat and lightweight for finish coats. Store unused mud in an airtight container.
