Herculiner is the only polyurethane and rubber granule coating that is applied in just 3 easy steps to your truck bed using rollers and a brush (included in the kit). When cured, Herculiner provides a tough, durable skid-resistant protective coating. Our proprietary solvent-based formula versus a water-based product allows Herculiner to adhere better when cured to the surfaces It's applied to. Because of its unique properties, it can bond to virtually any surface or material. Herculiner can be applied to wood, metal, concrete, aluminum, asphalt, rubber, fiberglass and most plastics, including PVC. Our product prevents rust by sealing the surface and is resistant to gasoline, oil, solvents and chemicals.
