Measuring Spray-on Truck Bedliner Thickness

DeFelsko’s PosiTector 6000 thick series of coating thickness gauges are ideal for non-destructively measuring the thickness of spray-on liner coatings applied to steel and aluminum truck beds.


Bedliner coatings are commonly used in the automotive and defense industries to protect from physical impacts, scratching, abrasion, and corrosion due to exposure, allowing for improved slip resistance. These coatings typically comprise 100% polyurethane, 100% polyurea, or a hybrid of both polyurethane and polyurea layers and are applied to truck beds made of steel or aluminum. Several spray-on bedliner coating manufacturers exist in the market, including ArmorThane, LINE-X, Rhino Linings, and Bullet Liner.

How Bedliners are Applied

Before starting the spray process, the entire truck bed surface is cleaned and sanded to assure that a strong bond can be established. Other preparations include removing the tailgate and other parts as necessary and masking the exterior to protect from overspray. Utilizing a nozzle in a well-ventilated area, the protective coating is applied in long sweeping motions and allowed to dry between coatings.

To match coating thickness requirements, multiple layers of bedliner are applied to all truck bed surfaces. A final texture coating may be applied to any coated areas that are too rough or too smooth. This guarantees a uniform texture and adequate slip resistance even in wet conditions. After a short curing period, the protective bedliner is ready for cargo.

The Importance of Measuring Bedliner Thickness

Bedliner coatings are usually applied between 3-6 mm (125-250 mils) thick. Enough coating layers must be applied so that the total thickness is within the range that the coating manufacturer has specified. Insufficient liner thickness will cause the coating to fail prematurely, exposing the truck bed to corrosion. Applying more than the manufacturer’s suggested thickness is simply a waste of time and money. Therefore, an instrument capable of accurately measuring the thickness of a cured bedliner is required to ensure optimal performance and cost savings.

DeFelsko’s Bedliner Coating Measurement Tool

PosiTector 6000 coating thickness gauges are perfect for measuring spray-on bedliner coatings’ thickness applied to steel and aluminum truck beds. Specifically, the PosiTector 6000 FT and PosiTector 6000 FTS instruments utilize the magnetic principle to measure and display the total liner thickness applied to steel beds. The PosiTector 6000 FNTS model uses magnetic and eddy current principles to measure bedliner thickness applied to either steel or aluminum truck beds accurately and quickly. Given the growing popularity of aluminum beds, the PosiTector 6000 FNTS provides a complete solution for applicators.
