How to Use This Calculator

Enter vessel or structure type, exposure zone (atmospheric, splash, immersion, or buried), and design life (years).
Select surface preparation standard: Sa 2.5 (near-white blast) is typically required for immersion zones.
Read recommended coating system specification: primer, midcoat, and topcoat with DFT per coat.
Review total dry film thickness (microns) and minimum recoat windows between coats.
Compare coating system options by total applied cost ($/m2) and expected service life.
