VFI®-543 Low Pressure Spray Bedliner

VFI®-543 Low Pressure Spray Bedliner

VFI-543 Low Pressure Spray Bedliner is a fast setting, 100% solids, polyurea hybrid bedliner. It creates a durable and rust preventive layer over any surface for long-lasting protection. As a low-pressure material, it is an economical option for a spray-on bedliner and is great for applications that don’t require rapid cure times. It has the ability to withstand cracking, warping, and peeling in extreme hot and cold temperatures. VFI-543’s polyurea hybrid technology provides high properties, including excellent tensile strength and elongation, to protect the surface from damage and extend its life.  

VFI-543 Low Pressure Spray Bedliner from VFI is a fast setting polyurea hybrid coating for applications that don’t need a fine texture or rapid cure times.

Instructions for Use:  

Surface Preparation  

The key to product performance lies within the preparation of the surface. If you are coating a truck bed, remove all hardware and accessories within the bed that you do not want to be sprayed. You can also remove the tailgate and spray it separately from the rest of the truck. Use acetone or MEK to clean all surfaces of oils, films, and detergents, and then allow them to dry. 

Use wire tape to accurately define the edge of the bed liner for impressively straight cuts. When applying the tape, position it along the desired trim line with the wire side facing the surface. With masking tape and plastic sheeting, cover the rest of the truck and any other areas that will not be coated. Ensure the plastic sheeting is enclosed over the surface to protect from overspray. 

Scuff all surfaces that are to be sprayed with a wire cup brush sander or 40-grit sandpaper. Do not sand to bare metal. Doing so could affect the integrity of the finish and cause the bed liner to peel eventually. Finish preparing the surface by cleaning the newly scuffed surface with acetone or MEK and allow it to dry before proceeding.  

More extensive surface preparation will depend on the substrate, as some may need a primer for ensured adhesion. VFI does not recommend using primers on properly prepared metal surfaces. For other substrates, one of our approved primers may be used to increase adhesion, including VFI-#11, VFI-1016, and VFI-1017. The primer you choose will depend on the substrate. 


VFI-543 Low Pressure Spray Bedliner must be brought to a minimum temperature of 65°F before use. Premix the B side (poly) until uniform before spraying. Mix times will vary depending on volume and mixing method. The surface temperature should stay between 40°F – 100°F while spraying and curing. If the temperature passes 72°F, the cure speed will increase. 

Wear proper PPE, including an approved respirator, and spray in a well-ventilated area with a low-pressure, plural component spray system. Plan your spray pattern ahead of time to allow for even distribution of the coating. Average coverage for the best results is 80 mils. When spraying a truck bed, VFI recommends starting with the vertical side and back panels before working down toward the end of the bed. As a low-pressure system, VFI-543 creates a rough, consistent texture that is slightly larger than a high-pressure spray truck bedliner. If more texture is wanted, spray over but not directly onto the surface until the desired finish is achieved.  

Allow the material to sit for at least 20 minutes before removing all wire tape, masking tape, and plastic sheeting. To remove the wire tape, pull at a 45-degree angle toward the coated surface. The sprayed surface should be ready for light use in as little as 4 hours and full use within 24 hours. Allow the surface 5 days to cure completely.  


When cleaning spray equipment, VFI recommends using xylene or MEK. Flush the cleaning solution through the spray lines until the material is completely removed.  


*Always read the safety data sheet before working with chemicals 

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste. 

PPE to avoid all unnecessary exposure:  

  • Eye protection – wear safety glasses and any additional eye protection as necessary 
  • Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene) 
  • Skin and body protection – wear suitable protective clothing 
  • Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator 

Product Limitations  

The A side of VFI-543 contains isocyanate, which may irritate the skin and can be toxic if inhaled. Avoid prolonged breathing of vapors and repeated skin contact by wearing the necessary personal protective equipment, including an approved respirator.  

  • Incompatible materials – A side: strong bases, acids, alcohols, amines, and water. B side: oxidizers 
  • Conditions to avoid – heat and incompatible materials  
  • Chemical stability – stable under normal storage conditions  
  • Reactivity & hazardous reactions – no dangerous reactions known under normal conditions 
  • Hazardous decomposition products – may include, and are not limited to, oxides of carbon. Also, oxides of nitrogen and isocyanates for the A side  

Potential Health Hazards  

  • May cause stomach distress, nausea, or vomiting if swallowed.  
  • May cause respiratory tract irritation. Components of the A side may also cause allergy or asthma symptoms and breathing difficulties.
  • Causes skin irritation and sensitization: redness, edema, drying, defatting, and cracking of the skin. Repeated exposure to components of the B side can result in absorption through the skin, causing a significant health hazard.  
  • Causes serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva.  

*If you are experiencing any of these symptoms, seek medical assistance or attention. Call a poison control center or doctor if swallowed.
