Here’s the calculation for any truck bed liner which is sprayed on:
1 gallon of any liquid covers 1604 sq ft at 1 mil (1/1000″).
Therefore:
total sq ft / (1604/mil height) = Gallons required to cover a specific area at a specific mil height.
Average Mil Height : Generally, for low stress areas you can go half the thickness of professional grade coatings. Therefore, if you are doing 20 sq ft @ 125 mils and you want to do 10 sq ft @ 60 and 10 sq ft @ 125 mils, your average = 125+60/2 = 185/2 = 92.5 average mil height
This is important when calculating actual material requirements. For floors, you do NOT want to use less than 30 mils when applying a protective coating. The mil height is required to provide the “protection”…… Be careful when reading other vendors product information because they typically do not expose this information in order to provide a “better price”.
