Paint Opacity Calculator — Coats & Coverage
Calculate the number of coats, paint volume and drying time based on pigment opacity, surface area and desired coverage.
How We Calculate This
This calculator uses the pigment opacity class and desired coverage level to estimate the number of coats, then calculates total paint volume.
The formula
Coats = Look-up by pigment opacity and coverage level
Paint volume = (Area / 100) x ml per coat x Number of coats
