What is the maximum coverage area for a gallon of joint compound?

  1. Approximately 50 square feet for a single coat

  2. Approximately 75 square feet for a single coat

  3. Approximately 100 square feet for a single coat

  4. Approximately 150 square feet for a single coat

The correct answer is: Approximately 100 square feet for a single coat

The maximum coverage area for a gallon of joint compound is approximately 100 square feet for a single coat. This figure is generally accepted in the drywall finishing industry and is based on standard practices for applying joint compound. When applying joint compound, factors such as the thickness of the application, the absorbency of the surface, and the technique of the finisher can influence the actual coverage, but for an average application, 100 square feet is a reliable estimate. This estimation helps contractors plan how much material to purchase for a given job, ensuring they have adequate supplies while minimizing waste. In comparison, the other coverage estimates suggest lower amounts, which are not typical for standard applications of joint compound.
