How to Use This Calculator
Measure your wall area (length × height, subtract doors/windows) and select surface type. The calculator accounts for different absorption rates and provides accurate primer quantity.
Why Accurate Primer Coverage Matters
Proper priming ensures paint adhesion, uniform color, and durability. Different surfaces absorb primer at different rates. Buying correct amounts prevents waste or mid-project shortages.
Common Mistakes to Avoid
Skipping primer on new drywall, using wrong primer type for surface, not accounting for texture, applying too thin (reduces coverage), and not stirring thoroughly.
