Important Estimating Notes & Practical Coverage Disclaimer
Calculated quantities are based on standard laboratory spread rates and represent theoretical coverage under optimal conditions without factoring in site-specific material loss.
In actual on-site painting, practical consumption commonly fluctuates by 10% to 20% (or more) due to real-world variables such as substrate porosity, surface roughness, application technique (roller, brush, or spray), dilution percentage, wet/dry film thickness, and color opacity changes.
