Calculating Actual Truck Bed Liner for Coating Project

Some folks claimed many speculations about how much coverage and how many square feet a product will cover. These assertions are proven or disproven by basic math. Here are the facts to consider when calculating square footage for how much bed liner is needed to paint your truck.

  • A gallon is a unit of measurement that equals 231 cubic inches in volume
  • The majority of coating recommendations are expressed in mils, which is equal to 1/1000th of an inch
  • At a maximum thickness of 1 mil, one gallon covers 1,604 square feet
  • Any single portion of liquid dries out or evaporates to lose some of its volume
  • If a liquid contains 40% VOC (the part that disappears), it will only cover 60% of a 100% solids product area

Using Simple Math Steps to Estimate Your Coating Needs

To calculate your actual coating needs, follow these three easy math steps:

  1. 1,604 / (your chosen thickness in mils) = A (true sqft per gallon)
  2. Your total project square footage / A = B (actual gallons necessary with 100 percent solids); skip and go to step 3 if you don't have 100 percent solids
  3. B / (percentage of solids in decimal) = C (required total gallons)

To give you an example, divide 1,604 by 100 to get 16.04 square feet per gallon for a 200 square foot area with a targeted thickness of 100 mils. Then divide that amount by the needed square footage (200) to obtain the minimum number of gallons. In this case, it would require 12.5 gallons for a 200 sqft area.

This is the sample solution:

1,604 / 100 = 16.04, then 200 / 16.04 = 12.47

One gallon would cover 25.46 square feet at 63 mil thickness (required minimum truck bed liner thickness). To calculate truck bed coverage, divide the total square footage by 25, giving the 63 mils gallons needed -using 100 percent solids two-part coatings with no waste.

If utilizing a one-part product, follow step 3 above. SL&C recommends using only two-part products to provide natural truck bed protection. Also, add 10% for trash.
