The short answer is generally no. While a Fluid Film spray gun can theoretically dispense bedliner material, it is not recommended due to fundamental differences in material viscosity, pressure requirements, and gun design. Using a Fluid Film gun for bedliner can lead to equipment damage, poor application quality, and overall unsatisfactory results.
Understanding the Discrepancies: Fluid Film vs. Bedliner
To fully grasp why using a Fluid Film spray gun for bedliner application is ill-advised, we need to examine the distinct characteristics of each material and their optimal application methods.
Fluid Film: A Thin, Penetrating Corrosion Inhibitor
Fluid Film is a lanolin-based rust and corrosion preventative. Its key characteristics include:
- Low Viscosity: Fluid Film is relatively thin, allowing it to penetrate seams and crevices effectively.
- Low Pressure Application: It’s designed to be applied with relatively low pressure, typically using airless or compressed air spray guns.
- Atomization Focus: The goal is to create a fine mist that coats surfaces evenly.
- Clean Up: Clean up is typically easy using mineral spirits or similar solvents.
Fluid Film spray guns are specifically designed to handle these properties. They are often equipped with nozzles that produce a wide, even fan pattern, ideal for coating large areas quickly.
Bedliner: A Thick, Durable Protective Coating
Bedliner, on the other hand, is a significantly different beast. It’s a thick, durable polymer coating designed to protect truck beds and other surfaces from abrasion, impact, and chemical damage. Key characteristics include:
- High Viscosity: Bedliner materials are significantly thicker than Fluid Film, requiring more force to atomize and apply.
- High Pressure Application: Specialized bedliner spray guns are built to handle the high pressures needed to properly apply the material.
- Texture Control: Depending on the desired texture, bedliner guns often have adjustable nozzles and air caps.
- Specialized Equipment: Many bedliners require plural component (two-part) mixing and dispensing systems.
- Complex Clean Up: Cleanup typically requires dedicated solvents and often involves disassembling the gun.
Bedliner spray guns are robustly constructed and engineered to deliver the high volumes of material at the pressures necessary for proper adhesion and texture. Trying to force bedliner through a Fluid Film gun is akin to trying to squeeze toothpaste through a coffee straw – it simply won’t work effectively and will likely damage the equipment.
The Risks of Using the Wrong Gun
Using a Fluid Film spray gun for bedliner application carries several significant risks:
- Gun Damage: The high viscosity of bedliner can clog and potentially ruin the delicate components of a Fluid Film spray gun.
- Inconsistent Application: You’ll likely get a patchy, uneven coating with poor adhesion.
- Poor Texture: Achieving the desired texture of a bedliner is impossible without the correct gun and pressure settings.
- Material Wastage: You’ll waste a significant amount of bedliner material due to improper atomization and application.
- Safety Concerns: Attempting to force bedliner through an unsuitable gun could lead to dangerous backpressure and potential equipment failure.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions to further clarify the differences between Fluid Film and bedliner applications:
FAQ 1: What type of spray gun should I use for bedliner application?
The correct spray gun depends on the type of bedliner material you’re using. For single-component roll-on or brush-on bedliners, no specialized gun is required. For two-part (plural component) spray-in bedliners, you’ll need a dedicated bedliner spray gun designed for that specific product. These guns often require a mixing system to combine the two components immediately before spraying. Consult the manufacturer’s specifications for the bedliner product you choose.
FAQ 2: Can I thin down bedliner to make it work in a Fluid Film gun?
Thinning down bedliner is strongly discouraged. Altering the viscosity of bedliner material can compromise its durability, adhesion, and overall performance. It will also still likely cause issues with a Fluid Film gun and won’t achieve the desired protective properties.
FAQ 3: What is the difference between an HVLP and an airless spray gun for bedliner?
HVLP (High Volume Low Pressure) spray guns use a high volume of air at low pressure to atomize the paint. While they can be used for some thinner bedliner materials with proper modification, they generally aren’t ideal for the thick, textured application most people associate with bedliners. Airless spray guns use high pressure to force the bedliner through a small nozzle, atomizing the material without relying on large volumes of air. They are more commonly used for thicker bedliner materials because they are better at handling high viscosity. Specific models are designed to spray textured coatings like bedliner.
FAQ 4: Are there any “universal” spray guns that can handle both Fluid Film and bedliner?
No, there isn’t a truly universal spray gun. While some high-end, adaptable spray guns might technically be able to dispense both, switching between the two materials would be a cumbersome and potentially messy process. The performance will also likely be sub-optimal for one or both materials. It’s best to use dedicated guns for each application.
FAQ 5: What pressure is required for spraying bedliner?
The ideal pressure for spraying bedliner depends on the specific product and the type of spray gun. Consult the bedliner manufacturer’s specifications for recommended pressure settings. Typically, airless bedliner spray guns operate at pressures ranging from 2000 to 3000 PSI.
FAQ 6: How important is proper surface preparation before applying bedliner?
Surface preparation is absolutely critical for successful bedliner application. This typically involves thorough cleaning, sanding, and the application of a primer specifically designed for bedliner materials. Proper surface preparation ensures optimal adhesion and longevity of the bedliner. Failure to prepare the surface adequately will lead to peeling, cracking, and premature failure of the bedliner coating.
FAQ 7: What safety precautions should I take when spraying bedliner?
Always wear appropriate personal protective equipment (PPE), including a respirator, gloves, eye protection, and protective clothing. Ensure adequate ventilation in the work area. Read and follow the safety instructions provided by the bedliner manufacturer. Many bedliner materials contain harmful chemicals that can cause respiratory irritation, skin sensitization, and other health problems.
FAQ 8: Can I use a brush or roller to apply bedliner instead of spraying?
Yes, you can apply some types of bedliner using a brush or roller. These are typically single-component materials. Roll-on or brush-on bedliners are a good option for smaller projects or areas that are difficult to reach with a spray gun. However, the texture and finish will be different compared to a sprayed-on bedliner.
FAQ 9: How much does it cost to have a professional apply bedliner?
The cost of professional bedliner application varies depending on the size of the truck bed, the type of bedliner material, and the labor rates in your area. Generally, expect to pay anywhere from $400 to $1000 or more for a professional spray-in bedliner.
FAQ 10: How long does bedliner take to dry and cure?
The drying and curing time for bedliner varies depending on the specific product and environmental conditions. Generally, bedliner will be dry to the touch within a few hours, but it may take several days to fully cure and reach its maximum hardness. Consult the manufacturer’s specifications for recommended drying and curing times.
FAQ 11: What are the benefits of using bedliner?
Bedliner provides numerous benefits, including:
- Protection against scratches, dents, and rust.
- Enhanced durability and longevity of the truck bed.
- Improved appearance.
- Increased resale value.
- Slip resistance.
FAQ 12: What are some common problems with bedliner and how can they be prevented?
Common problems with bedliner include peeling, cracking, fading, and chipping. These problems can be prevented by:
- Proper surface preparation.
- Using the correct spray gun and pressure settings.
- Applying the bedliner in accordance with the manufacturer’s instructions.
- Avoiding exposure to harsh chemicals and extreme temperatures.
- Regular maintenance and cleaning.
