Spray-On Bed Liner: Diy Guide For Your Truck

how to paint bed liner on your truck body

Painting a bed liner on your truck body can be a great way to rejuvenate an old, scratched vehicle or add texture to a new one. While it may not be the best option for those concerned with the cosmetic appearance of their truck, it can be a good choice for those who want a quick, affordable, and durable solution. Before starting, it's important to prepare the truck's surface by removing any existing liner, cleaning and sanding the paint, and using masking tape to protect untreated areas. Depending on the product, you may also need to mix the bed liner components. When applying the bed liner, it's recommended to use multiple thin coats rather than one thick coat. Let each coat dry thoroughly before applying the next, and use a paint gun for a smoother finish. Finally, allow the liner to cure for 24-48 hours before using the truck.

Preparation and safety

Painting a bed liner onto your truck body is a great way to protect it from scratches and dents. However, it requires careful preparation and the right tools. Here are some detailed preparation and safety instructions to help you get started:

Preparation

  • Clean the surface thoroughly: Start by removing any existing bed liner or flaking paint. Use a pressure washer or a wax-free soap and warm water to remove all dirt, grime, and debris from the truck bed, including the corners and seams.
  • Prepare the surface for sanding: Once the truck bed is clean and dry, use a grease and wax remover to ensure the bed is ready for sanding.
  • Sand or scuff the surface: Scuff the entire surface with a scouring pad to create a rough texture that will help the bed liner material adhere properly.
  • Mask off areas you don't want to coat: Use painter's tape and drop cloths to cover any areas you don't want to be coated, such as glass, chrome, or painted areas. This includes the top of the bed rails, hardware, and tonneau cover mounting clamps.
  • Choose a well-ventilated work area: Bed liner paints can produce strong fumes, so it's important to work in a well-ventilated area to ensure your safety.

Safety

  • Wear protective gear: Make sure to wear appropriate protective gear, including gloves, eye protection, and a respirator to safeguard against fumes.
  • Consult the product's safety data sheet: Always refer to the product's safety data sheet for specific instructions and precautions. This will help you identify any special safety measures you need to take during the application process.
  • Be cautious of moisture: While a bed liner can protect your truck, trapping moisture underneath it can lead to corrosion. Ensure the truck bed is thoroughly cleaned and dried before applying the bed liner.
  • Consider professional application: Applying a bed liner yourself may devalue the vehicle and make future bodywork more challenging. Professionals use high-pressure equipment and expert techniques to achieve a durable and uniform finish, often backed by a warranty.

Remember, proper preparation and safety measures are crucial to achieving a successful and safe bed liner application. Take your time, follow instructions, and don't hesitate to seek professional advice if needed.

Choosing a colour and texture

When it comes to choosing a colour and texture for your truck's bed liner, there are a few things to consider. Firstly, decide on the desired finish. Do you want a smooth or textured finish? A smooth finish will give your truck a flat, even look, while a textured finish can add grip and a unique appearance.

If you opt for a textured finish, consider the level of texture you want to achieve. Some bed liner products offer different levels of texture, from a subtle stipple effect to a more aggressive, grippy texture. Choose the one that best suits your preferences and the intended use of your truck.

Colour is another important consideration. Bed liners come in a variety of colours, including black, brick red, bright red, brown, cream, various shades of blue and grey, military olive, orange, sand, tan, white, yellow, and even clear. Think about how the colour will complement the overall look of your truck and whether you want a bold statement or a more subtle approach.

Additionally, keep in mind that some colours may fade over time, especially when exposed to sunlight. For example, black can fade to dark grey, red can turn pink, and blue can become light blue. If you want to maintain the original colour, consider using a clear coat over the bed liner to add an extra layer of protection and vibrancy.

Finally, if you plan to paint over the bed liner, ensure you choose a compatible paint type. Polyurethane-based paints are typically recommended as they offer better pliability and longevity. They can be found in various colours, although they may be harder to source. Applying the paint within 24 hours after the bed liner has dried will yield the best results.

Application methods

There are several methods for applying bed liner paint to your truck body. The most common methods are using a roll-on kit or a spray-on kit. You can also use a paint gun to apply the paint.

Roll-on Kit

Roll-on bed liner kits are a good choice for DIY users as they are affordable and can yield a decent protective layer. However, the results may not be as uniform or durable as a professional job. When using a roll-on kit, follow the general steps for a typical bed liner application:

  • Remove any existing liner and clean the surface thoroughly.
  • Sand or scuff the paint to help the coating adhere better.
  • Mix the bed liner components as instructed.
  • Apply the first coat.
  • Let the first coat dry, then apply a second coat (and a third if needed) to reach the recommended thickness.
  • Allow the liner to cure fully (usually 24-48 hours) before heavy use.

Spray-on Kit

Spray-on bed liner kits are also available for DIY users, but they may be more difficult to apply evenly and smoothly. Plural component spray-on systems are typically used by professionals and can give a more durable and even finish. When using a spray-on kit, follow similar steps as the roll-on kit, but be sure to thin out the material before spraying and apply multiple thin layers for a smoother finish.

Paint Gun

Using a paint gun can give you more control over the application process and help you achieve a smoother finish. Thin out the material before spraying and apply multiple thin layers to avoid a textured look.

Drying and curing

To accelerate the drying process, consider using a liquid accelerator like Durabak Accelerator, which can reduce drying time by up to 50%. This is especially useful in low atmospheric conditions or when a quick drying and curing time is needed.

While some sources suggest that 24 hours is sufficient for the bed liner to cure, others recommend waiting up to 48 hours before using the truck bed or washing it. The curing time can vary depending on the product, with some taking about two weeks to fully cure. To speed up the curing process, park your truck so that the bed is facing the sun.

If you are in a hurry and need to use the truck bed before the recommended curing time, it is generally safe to "handle" it a few hours after application, depending on the thickness of the coat. However, it is important to avoid any rough or heavy work during this period, as the liner may not be fully hardened.

In some cases, additional steps like baking the coated surface in an oven or using a self-etching primer may be taken to aid the drying and curing process. These steps can help harden the coating and improve its durability.

Maintenance and durability

Painting a bed liner on your truck body can be a great way to rejuvenate an old, scratched vehicle, change its colour, or simply free yourself from concerns about the cosmetic appearance of your truck. However, it is important to consider the maintenance and durability of such a paint job.

Firstly, it is important to note that a bed liner paint job will not be entirely scratch-proof. Regularly inspect the bed liner for any signs of scratches or abrasions. Small scratches can be fixed using touch-up coatings, which will help prevent them from turning into bigger problems that can harm the protective layer.

To maintain the integrity of the bed liner, it is important to keep the surface clean. Use a mild soap and water solution, along with a soft brush or cloth, to regularly clean the bed liner surface. Avoid using abrasive materials or harsh chemicals, as they may damage the bed liner. Certain chemicals, such as gasoline, bleach, and harsh solvents, can cause accelerated wear and tear, so be sure to clean up any spills immediately.

Additionally, bed liners are susceptible to UV damage from prolonged exposure to sunlight and UV rays, which may cause the material to fade and degrade over time. To mitigate this, try to park your truck in shaded areas, and consider using a UV protectant made specifically for spray-in bed liners.

It is also important to consider the prep work before applying the bed liner paint. To achieve a long-lasting, smooth, and durable finish, the truck body must be meticulously cleaned, sanded, and degreased. Any spots that are missed may result in the bed liner not adhering properly, leading to bubbles, peeling, or cracks over time.

Finally, while a bed liner paint job can provide protection and durability, it is important to be aware of the potential impact on the value of your vehicle. A bed liner paint job may devalue the vehicle and make any future bodywork more difficult. Additionally, moisture trapped behind the liner can cause rot and corrosion, so it is crucial to address any issues with the coating promptly.
