Glossary: Paint Coverage
**Paint Coverage** is the volumetric yield of topcoat liquid paint over a surface, standardized as 350 square feet per US gallon (8.59 square meters per liter) on smooth sealed substrates.
Paint Sizing Calculations
Paint yields depend on surface porosity and texture. Drywall primers seal gypsum pores to maximize coverage yields. 1 US gallon yields 350 sq ft of coverage, while 1 Litre yields 8.59 sq m.
