📦 ASTM E605 (Dry Density 15-22 PCF Standard vs 40+ PCF High-Density, BdFt/Bag)

SFRM Fireproofing Yield & Density Calculator

Calculate material bag consumption, coverage yield, and dry in-place density for spray-applied fireproofing under ASTM E605: calculate theoretical vs actual bag yield (Board Feet per 45-lb or 50-lb bag accounting for 10% to 20% overspray loss), verify minimum required dry density (15 PCF standard interior, 22 PCF conditioned, 40+ PCF parking garages), and contractor margins.
