Instructions for Use:  

Surface Preparation 

Before spraying VFI-544 Qwik Spray Bedliner, all surfaces must be free of any oils, dirt, or films that may affect adhesion. When spraying a truck bed, remove all hardware within the bed that you don’t want to be sprayed. The tailgate can also be removed and sprayed separately from the rest of the truck bed. Clean all surfaces with acetone or MEK and allow the cleaning agents to dry.  

Use wire tape for clean-cut lines and to define the edges of the bed liner. Place the wire on the inside and the tape on the outside of the cut line. Masking tape and plastic sheets can be used to cover all other areas that need protection from overspray. 

Once all surfaces are covered, scuff all areas to be sprayed with a wire cup brush sander or 40-grit sandpaper. Avoid sanding to bare metal, as this can affect the adhesion of the bed liner, causing it to peel over time. After scuffing, use acetone or MEK again to clean the surfaces and allow them to dry before spraying.  

While primers aren’t recommended on properly prepared metal surfaces, they can be used to increase adhesion on other surfaces. VFI offers a handful of approved epoxy and urethane primers for just about any surface, including VFI-#11, VFI-1016, and VFI-1017. The primer chosen will depend on the application.  

Application 

The Qwik Spray System does not need special training to operate. VFI-544 requires a plural component VFI-7500 Qwik Spray Applicator Gun with dual 300 mL cylinders. To operate the gun, you will need an air compressor that can provide dry air and a minimum of 10 CFM at 100 PSI of constant pressure. Ensure you are in a well-ventilated area before spraying, and wear the proper PPE, including an approved respirator. 

The material should be brought to a minimum of 75°F before use. Mixing is not required unless the material is visibly separated, and if so, the cartridge should be shaken until uniform. The temperature should be between 40°F – 100°F during use. The cure speed will increase if the temperature passes 72°F. Once you start spraying, you cannot stop, so carefully plan your spray pattern ahead of time for even distribution. Start with the vertical side and back panels and work down toward the end of the truck bed.  

To use VFI-544, connect the Qwik Spray applicator to a dry air source. Keep the cartridge vertical with the label facing up when loading it into the gun. Start by spraying onto a disposable surface to ensure the material is adequately mixed. VFI recommends spraying at 80 mils for the best results. Do not stop your spray pattern until the cartridge is empty. Once the cartridge is almost used, spray onto a disposable surface to keep off-ratio material from getting onto the truck bed. 

To apply texture, spray over but not directly onto the surface until the desired finish is achieved. Allow the material to set for at least 20 minutes before removing the tape and plastic. To remove the wire tape, pull at a 45-degree angle toward the sprayed surface. Once cured, it is ready for light use in as little as 4 hours and full use in 24 hours. Allow 5 days for full cure.   

Cleanup  

A feature that makes the Qwik Spray System so desirable is easy cleanup. Simply disconnect the disposable cartridges from the air-atomizing gun tip, remove them from the applicator frame, and throw them away. If there is residue on the gun or other equipment, use xylene or MEK before it sets. Never soak the gun in any cleaning solvent.  

Safety  

*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 contains isocyanate, which can irritate the skin and be toxic if inhaled. Avoid prolonged breathing of vapors and repeated skin contact by wearing the proper personal protection 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 reaction known under normal use 
• 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. A side components 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 B side components 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.
