How much bedliner do I need?
Comparing the recommendations for truck bed coatings from the pros
Spray lining complaints can be avoided by ensuring you bypass fake names or titles some spray liner companies can use. We expose some of the common mistakes and misunderstandings below with some simple advice.
These issues summarize coating truck bed requirements:
- Cost of product (the natural sprayable liquid per sq. ft. at certain height)
- Cost of the service for bedliner applicator
- The specific coating qualities and application method employed
- Ensuring enough liquid is being applied to provide correct thickness
While the cost of any product you choose is your first consideration, it is easy to understand that you can avoid many problems which lead to complaints by also considering other factors. There are coatings for “general” applications and more specific coatings for exacting requirements. For a successful and complaint free Pickup Truck Bed Lining, consider the other requirements which affect quality.
A good truck bedliner includes materials with very high strength and a slip-proof texture; other issues like UV stability for long term protection and color should be considered as well. Specific application method, i.e. spray-on technique may also differ, but no bedliner of any quality is ever rolled. There are products offered which the promise of providing complete coverage with one gallon, but we consider these claims to be a scam and encourage others to avoid them.
A gallon of truck bedliner or any liquid has only so much coverage capacity. One gallon covers 1,604 sq. ft at 1 mil high (1 mil = 1/1,000 of an inch). Even the lowest coverage recommendations from Spray-lining competitors suggests 63 mils.
Just to cover the bed flooring of a compact truck (approx. 24 sq. feet) with no waste requires 1 gallon of material with no waste. To cover the inside walls and wrap over the rails (approx. 65 sq. feet) requires 2 ½ gallons of the same compact truck bed.
Recommendations for truck bed liners from the experts:
1- Under 1/16 inch or 63 mils is lower quality
2- 1/16 to 1/12 inch or 63 to 83 mils is good quality
3- 1/12 to 1/8 inch or 83 to 125 mils is high quality
4- Over 125 mils is best quality
While many factors determine you coverage needs and the actual area of coverage, you can estimate your square footage requirements with three measurements.
- Measure the inside of your truck bed at the longest point for length, width, and depth (in inches).
- Multiply the length by the width and record the number.
- Add the length plus the width and multiply by 2 (this equals all four sides of bed).
- Multiply that by the depth (if you are wrapping over top of rails, add 2 inches to the depth before multiplying).
- Add the result to the measurement in step 2 and divide the results by 144.
This calculation will provide a rough idea of the total square footage, but it is always recommended to add for overspray, waste, and surface irregularities. Spray-Lining provides a quality product and wants your truck bedliner to be complaint free. For this reason, we suggest estimating 10 to 20 percent additional materials. If the additional is not needed, it can be applied later to provide even more truck bed protection.
It’s easy to see that the amount of product required can vary greatly, but whether you choose Spray-Lining, or another brand, the required product for proper coverage remains the same. Don’t be misled by false claims of coverage. Be sure to always factor in the actual product required, not the promise to protect your truck bed with a single thin layer of coating.
When deciding on what product and/or application professional to use, while certain qualities should be clearly stated, printed or displayed, the actual amount of sprayable liquid can be seemingly unclear. In USA this amount translates directly to the thickness known as “mil height” (thousandths of an inch which may be in millimeters in Canada). Mil height is measured with a mil gauge, or you’d simply grab a thick needle with pliers and push the needle through the liner until it hits the metal bed, mark the needle to measure that distance.
You can avoid misrepresentation by other spray on bedliner dealers by better understanding the amount of sprayable liquid needed for your spray lining to function correctly in your truck bed.
