Studies Show STK Drop-In Bed Liners Offer Safe Alternative to Spray-On Bed Liners

Share Article

In recent studies, toxic chemicals in spray-on bed liners have generated concern about health risks posed by these products. STK's drop-in bed liners offer a safe, easy and less expensive alternative.

Spray-on bed liners have been popular as an alternative, but we're finding now that they are actually quite dangerous

Spray-on bed liners may not be as safe as originally thought, according to the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA). Spray-on bed liners contain toxic chemicals called diisocyanates, which have been found to have harmful effects on the health of workers and do-it-yourselfers.

Luckily, there is a safe alternative to spray-on bed liners: custom molded plastic bed liners, known as drop-in bed liners.

"Spray-on bed liners have been popular as an alternative, but we're finding now that they are actually quite dangerous," said Bob Moore, marketing manager of

Health and safety concerns associated with spray-in bed liners include skin irritation such as itching and hives, lung impairment such as asthma and chemical bronchitis, nocturnal wakening, and even death. Some of these effects can last for months or years. Equally as important, exposure to these chemicals creates sensitization, which means that next time the individual is exposed to the chemicals, his or her reaction can be much worse.

To avoid overexposure, spray-on bed liners must be applied in well-ventilated, non-confined areas. However, the shape of the truck bed naturally creates confinement, making it difficult to limit exposure to the chemicals.

STK Drop-In Bed Liners, on the other hand, pose no such health risks and typically cost less than half of most spray-in bedliners. These bed liners are made of heavy duty plastic which is custom molded for each specific truck's make and model and are also easy and safe to install. They do not require the evasive sanding of the truck bed necessary to apply a spray-in bedliner.

Drop-in bed liners also offer superior protection. "Drop a cinder block on your spray-in and you will most likely have a nice dent in your bed or sidewall," Moore said. Scratches and dents caused by shifting cargo compromise a spray-in bed liner and enable rust to get through. Additionally, spray-on bed liners require yearly re-application of UV-protective sprays. Drop-in bed liners require no maintenance.

Drop-in bedliners are 100% recyclable keeping them environmentally safe as the nation goes green, while Spray-in bed liners render the entire truck bed as unrecyclable.

"Whether you are concerned about your safety, would like to save money or just want an easy installation, drop-in bed liners are clearly the better choice," Moore said.
