Terms

mil •  a unit of measurement equal to ¹/₁₀₀₀ inch used especially in measuring the thickness of coatings.

Not to be confused with:

millimeter  •  a unit of length equal to ¹/₁₀₀₀ of a meter and equivalent to 0.03937 inches. Abbreviation: mm

*NOTE:  Calculated coverage rates do not account for surface irregularities or transfer loss (example: product left in a bucket or roller cover). Coverage rates listed on technical data sheets (TDS) will vary based on floor type, system selected, and floor porosity. It is always recommended to "round up" when ordering product to account for these things.
