Frequently Asked Questions

Instructions for Use:  

Surface Preparation  

For optimal adhesion, all surfaces should be clean and free of oils, dirt, or films. Remove all damaged material. Scuff around areas you are repairing with a wire cup brush sander or 40-grit sandpaper. Clean surfaces with acetone or MEK and allow the cleaning agents to dry.  

Application 

VFI-520 can be used with the plural component VFI-7500 Qwik Spray Gun or brushes. You should only apply in a well-ventilated area and wear all necessary PPE, including an approved respirator. Bring the material temperature to a minimum of 65°F before use. The surface temperature should be between 50°F – 100°F during application. The cure speed will increase if the temperature passes 72°F. 

  • Brush application – Combine the A and B side materials and mix until it turns into a thick paste that is capable of hanging on vertical surfaces. Apply the repair material to all areas in need of renewal. A textured mat can be placed over the repair material while it cures to create a consistent finish with the surface. Texture can also be applied by spraying VFI-542, VFI-543, or VFI-544.  
  • Qwik Spray application – The cartridge version does not require mixing unless visibly separated. If separation occurs, shake the cartridges until uniform. Keep the cartridges vertical with the label facing up when loading it into the gun. For vertical surfaces, inject material into a cup and wait for the thickening reaction to occur. When using the Qwik Spray System, it is shot as a stream. Apply the repair material to all areas in need of renewal. A textured mat can be placed over the repair material while it cures to create a consistent finish with the surface.  

Cleanup 

When using the Qwik Spray System, remove the cartridges from the applicator frame and throw them away. Never soak the gun in any cleaning solvent. Use xylene or MEK to clean residue on other application equipment.

Frequently Asked Questions

How much does it cost?

VFI strives to keep our prices competitive, but it ultimately depends on the availability of raw materials and the materials used in the formula. Also, polyurea hybrids when compared to pure polyurea coatings provide a good balance of properties, moisture insensitivity, and price.

What happens if the bedliner is damaged? Is it repairable?

Yes, Volatile Free, Inc. offers a bedliner repair material called VFI-520 QS Bedliner Repair that you can use on scratches, blisters, and other damages. It can be applied by brush or injected using the VFI-7500 Qwik Spray Gun.

How to clean spray on bedliner?

Regularly remove dirt, debris, and other grime that has built up from use. You can use a hose or a pressure washer to clean the truck bed with soap and water. Avoid harsh chemicals that may damage the material.

How long do polyurea hybrid coatings last?

When applied correctly and regularly maintained, a spray on truck bedliner should last the entire life of the truck. If repair is needed, VFI offers a thickened polyurea hybrid as a repair material for scratches, gouges, and other blemishes.

Will the bedliner fade over time?

Yes. All VFI bedliners are aromatic, which means they are not UV-stable. If you want to maintain the color of your bedliner, you’ll need to apply a clear aliphatic top coat like VFI-2580.

How soon can the truck bed be used after spraying?

We recommend waiting at least 4 hours after application for light use of your truck bed and a full day (24 hours) before heavy-duty use. The bedliner will gain full strength and formulated properties 5 days after application.

How much material do I need to coat a truck bed?

When spraying VFI-544, we recommend using 6 cartridges (a full case). A full case is just under 2 gallons of material and gets you around 100 mils thick without any loss.

VFI-542 and VFI-543 can be ordered in drums or totes, so about 2 gallons from those containers will also coat one truck bed at around 100 mil thickness without any loss.

How thick should I apply the bedliner?

VFI recommends applying the material at a minimum of 80 mils for long-lasting results.

How long does it take to spray a truck bed?

It can take 2-4 hours to prepare the surface by sanding or priming, tape off areas you don’t want material to get onto, and then spray the truck bed.

Do I need a primer?

Primers are usually not required on properly prepared metal surfaces. Scuff the areas you are coating with a wire cup brush sander or 40-grit sandpaper. If you need a primer, VFI recommends either VFI-1016 Steel Primer or VFI-1017 Porous Surface Primer.

What surface prep is required before applying spray on bedliner?

The surface must be cleaned with acetone before application. Tape up the truck bed with wire trim tape and shield surfaces from overspray with plastic or paper sheets. Scuff sand the area you are coating with a wire cup brush sander or 40-grit sandpaper. Primers are usually not required if the metal is properly prepared.

What temperature should I use the material at?

VFI spray on bedliners must be sprayed between 40°F and 100°F. The cure speed of the material will increase if the temperature passes 72°F.

Does your spray on bedliner come in different colors?

VFI high-pressure, low-pressure, and Qwik Spray bedliners can be pigmented. The premium colors offered are light gray, red, blue, pewter, yellow, and green. These materials are not UV color stable and require an aliphatic top coat like VFI-2580 to prevent fading.

What kind of packaging do your bedliners come in?

For our high pressure bedliner, it can be purchased in drums or totes. The low pressure bedliner can be purchased in pails, drums or totes. The Qwik Spray formula comes in cartridges with 6 cartridges per case.

Is high pressure material better than low pressure material?

While some manufacturers will tell you that high pressure is better than low pressure bedliners, they both perform as expected. Our low-pressure spray bedliner is an economical option with a lower hardness (40 A) and a slightly slower cure than our high-pressure version. It may provide a slightly thicker texture, better for skid resistance. Either version will still provide the same quality and durability.

What are the application options for your bedliner?

VFI spray on bedliner comes in three formulas: high pressure, low pressure, and Qwik Spray for different processing needs.

Does the spray on truck bedliner withstand temperature extremes?

VFI bedliners offer extended protection from wear in extreme temperatures while maintaining flexibility to prevent cracking. They also form a seamless membrane to keep water from penetrating the surface, preventing rust and corrosion.

How are spray in bedliners better than drop in liners?

Spray in bedliners offer more durability than drop in liners. Drop in liners have to frequently be replaced because they crack, break, and warp over time. Spray in bedliners are an almost permanent solution to protect your truck bed. They form a seamless film over the prepared metal to keep out dirt, debris, moisture, and other contaminants. They are more likely to last the entire lifetime of your truck.

What is the difference between an aliphatic and aromatic bedliner?

Aliphatic bedliners are UV stable and will not fade over time, while aromatic bedliners will fade and chalk over time when in direct sunlight. Most bedliner on the market are aromatic, but VFI offers a clear aliphatic top coat to prevent color fading and degradation.

What is your spray on bedliner made of?

VFI’s bedliners are a cost-effective blend of both polyurethane and polyurea. They offer the best characteristics of each material, including properties, cost, and moisture sensitivity.
