Instructions for Use:  

Surface Preparation  

Before applying VFI-542 High Pressure Spray Bedliner, the surface must be properly prepared to ensure adhesion and prevent peeling. When spraying a truck bed, remove all hardware and accessories that you do not want to be sprayed. Clean all surfaces with acetone or MEK to remove any oil, films, or detergents that could affect adhesion. Allow your cleaning agents to dry before taping up the truck bed. For clean-cut lines, use wire tape to define the edges of the bed liner on the surface. Place the wire on the inside and the tape on the outside of the cut line. Use masking tape and plastic sheets to cover the rest of the truck or any areas you want to protect from overspray. 

Scuff the area where the coating will be applied with a wire cup brush sander or use 40-grit sandpaper. Avoid sanding to bare metal to keep the integrity of the truck finish. Applying VFI-542 to bare metal could otherwise cause the bed liner to peel off from the surface over time. Once scuffed, clean the surface again with acetone or MEK and allow it to dry. 

To increase the adhesion of VFI-542 on certain surfaces, one of VFI’s approved primers should be used (VFI-#11, VFI-1016, or VFI-1017). The selected primer will depend on the application. Primers are usually not required on properly prepared metal surfaces. 

Application 

VFI-542 should be used by a trained applicator who has experience using a high-pressure, plural-component spray system. The high-pressure spray rig should be able to provide a minimum 2000 PSI of constant pressure. Before using VFI-542, bring the material to a minimum temperature of 65°F. As a two-component product, the B side (Poly) must be premixed until uniform before spraying. The time it takes to mix will depend on volume and mixing method. Ensure you are in a well-ventilated area and using all the necessary PPE, including an approved respirator.  

The temperature should be between 40°F – 100°F during application. The cure speed will increase if the temperature passes 72°F. Carefully plan your spray pattern for even coating distribution. Start with the vertical side and back panels before working down toward the end of the truck bed. Spray until desired thickness is reached on all surfaces. VFI recommends applying the bedliner at 80 mils. As a final step for 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 coverings. To remove the wire tape, pull at a 45-degree angle toward the sprayed surface. Remove all plastic sheeting and masking tape before reassembling hardware and accessories. The surface should be ready for light use within 4 hours and full use within 24 hours. Full cure can be achieved in 5 days.  

Cleanup 

VFI recommends the use of xylene or MEK when cleaning spray equipment. Flush the cleaning solution through spray lines until the bed liner is completely removed.  

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  

Isocyanate in the A side may be irritating to the skin and toxic if inhaled. Avoid prolonged breathing of vapors or repeated skin contact by wearing the proper 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 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. Components of the A side may also cause allergy or asthma symptoms and breathing difficulties.  
• May cause skin irritation: redness, edema, drying, defatting, and cracking of the skin. Repeated exposure to the 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.
