Frequently Asked Questions

Instructions for Use:

Surface Preparation

The repair area should be clean and free of oils, dirt, films, and other contaminants that could affect adhesion. Hairline cracks must be saw-cut. Open up the crack to a minimum of ¼” wide by ¼” deep using a dry diamond blade. Remove all dust by vacuum or compressed air from the cut-out area. All areas receiving VFI-5055 should be dry before application. Concrete must be aged at least 28 days before the patch repair is used. If the area needing repair is damp or wet, it must be primed and allowed to set for 10-60 minutes, depending on temperature.

Application

Before combining the A (Iso) and B (Poly) materials, premix the B side. Measure the B side before pouring it into the measured A side material and mix together until uniform. Transfer the material into a clean mixing container and mix once more before use. The product must be thoroughly mixed and used before the end of the pot life. Mix times may vary depending on the volume of material used and the mixing method. When in use, the temperature should be between 50°F – 100°F with the material at a minimum of 65°F. Higher temperatures and larger quantities will shorten the pot life.

Mix VFI-5055 with dry industrial quartz sand or a similar filler when repairing larger areas or resurfacing broken concrete. The filler should be free of moisture and have an average grit size between 30 and 60. Coverage will vary based on the size of the aggregate used. Treat cracks and spalled areas with the patch material, then fill with sand. For deep repairs, build up in layers until it is level with the concrete. Finish the repair by running a trowel across the material until smooth. Do not overwork the material, or it may cause the repair to look rough. The repair will be traffic ready in 10 minutes at room temperature.

Cleanup

Application equipment, tools, and surfaces can be cleaned with xylene or MEK before the material cures. If the material has cured, use a grinder to remove it.

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:

  • Hand protection – wear chemically resistant protective gloves (nitrile, butyl, neoprene)
  • Eye protection – wear chemically resistant safety glasses or goggles when handling the material
  • Body and skin protection – wear suitable protective clothing that covers all exposed skin
  • 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

VFI-5055 is not a joint filling material and is not intended for use where substrate movement is required. It is not UV color stable and has no long-term UV testing. The material contains isocyanate, which can irritate the skin and is toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors or repeated skin contact. Keep the material away from moisture to prevent it from bubbling or foaming. Wet or damp areas must be primed and allowed to set before repair.

  • Incompatible materials – strong 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

Potential Health Hazards

  • May cause respiratory tract irritation. A side material may also cause allergy and asthma symptoms or breathing difficulties if inhaled.
  • Causes skin irritation or sensitization: redness, edema, drying, defatting, and cracking of the skin.
  • Causes serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva.
  • May cause stomach distress, nausea, or vomiting if swallowed.

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

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.
