Preparation is key

First, remove any loose material from the area to be treated. This includes rust, which can be removed with a rust remover or by sanding. If you are applying the bed liner to a painted metal surface, it is recommended to use an etch primer containing phosphoric acid to create an anti-corrosion barrier and improve adhesion. For plastic surfaces, an adhesion promoter should be used before applying the bed liner to ensure proper adhesion. It is important to clean and degrease the surface to remove any organic or petroleum-based contaminants that may interfere with adhesion. This can be done with a wax and grease remover or soap and water.

After the surface is clean and dry, it is important to sand it to roughen the surface and create a better adhesion for the bed liner. For plastic surfaces, it is recommended to use fine-grit sandpaper, such as 600-grit sandpaper. Once the sanding is complete, it is important to reclean the area to remove any dust or debris before applying the bed liner. It is also recommended to apply a primer to the surface, especially if the plastic is difficult to sand.

Finally, it is important to follow the directions provided by the bed liner manufacturer for the application process. This may include mixing the bed liner with a paint mix stick and pouring it into a roller tray or using an applicator gun, roller, brush, or aerosol, depending on the product and your preference. By taking the time to properly prepare the surface and follow the manufacturer's directions, you can achieve a durable and protective finish when applying a bed liner to plastic.

Use an adhesion promoter

When applying a bed liner to plastic, using an adhesion promoter is highly recommended. Adhesion promoters are especially useful for plastics, which can be challenging to paint due to their smooth and flexible surfaces. By using an adhesion promoter, you can achieve superior bonding and ensure that your bed liner adheres securely to the plastic surface.

There are various adhesion promoters available on the market, such as the Custom Coat Adhesion Promoter, which comes in a 12-ounce spray can. This product is designed for hard-to-sand areas and can be used on various automotive surfaces, including plastics, aluminum, fiberglass, and galvanized surfaces. It offers excellent coverage and superior bonding properties, making it an ideal choice for preparing plastic surfaces for bed liner application.

To use an adhesion promoter effectively, follow these steps:

  • Prepare the plastic surface by sanding it thoroughly. Use sandpaper with a suitable grit size, such as 400 or 600 grit, to roughen the surface and create a better profile for adhesion.
  • Clean the sanded surface with a wax and grease remover to eliminate any contaminants that may interfere with adhesion.
  • Apply the adhesion promoter by spraying it onto the prepared surface. Follow the manufacturer's instructions for proper application techniques and safety precautions.
  • Allow the adhesion promoter to dry completely according to the manufacturer's recommendations.
  • Once dry, you can proceed with applying your chosen bed liner product, following the specific instructions for that product.

By following these steps and using an adhesion promoter, you can significantly improve the adhesion of your bed liner to plastic surfaces, resulting in a durable and long-lasting finish.

Apply two coats

Applying two coats of bed liner to plastic requires careful preparation and the right tools for a durable finish. Here is a detailed guide:

Preparation:

Firstly, select a suitable bed liner product, such as Herculiner, Rustoleum, or Duplicolor Truck Bedliner. These products are recommended by users for their effectiveness on plastic surfaces. For the application process, you will need tools like sandpaper, a pressure washer, adhesion promoter, a roller, tray, and applicator gun or spray gun.

Surface Preparation:

Before applying the bed liner, prepare the plastic surface thoroughly. Start by removing any loose material, then clean and degrease the surface to eliminate contaminants. Next, sand the surface with fine-grit sandpaper (600-grit is recommended) to roughen it and promote better adhesion. After sanding, re-clean the area to ensure it is free of dust and debris.

Applying the First Coat:

Now, you are ready to apply the adhesion promoter, following the manufacturer's instructions. Once the promoter is dry, carefully mix your chosen bed liner product, ensuring it is thoroughly combined. Pour the mixed product into your roller tray. Using your roller, saturate it in the tray, then tap the roller to avoid excess product buildup. Starting at the top of the plastic surface, evenly roll on the first coat.

Applying the Second Coat:

After completing the first coat, allow it to dry for at least 30-60 minutes. The drying time may vary depending on the manufacturer's instructions, so refer to their guidelines as well. Once the first coat is dry to the touch, repeat the application process for the second coat. Carefully roll on the second coat, ensuring even coverage.

By following these steps and allowing adequate drying time between coats, you will achieve a durable and protective finish on your plastic surface.

Use a roller

Using a roller is a great way to apply a bed liner to plastic. It is a simple and cost-effective method that can give you great-looking results. Here is a step-by-step guide on how to use a roller to apply a bed liner:

Preparation:

Firstly, it is important to prepare the surface. Clean any heavy dirt, grime, dust, leaves, or water from the surface using a leaf blower, shop vac, or a cloth. If there is any oil, grease, or paint spill, clean it with mineral spirits. If there is any loose, peeling paint or rust, use sandpaper or a wire brush to clean it and ensure the surface is smooth. After sanding, pressure-wash or wipe down the surface with a rag and alcohol to remove the dust. You can also use solvent and fresh paper towels to degrease the bed, wiping in one direction from front to back.

Priming:

Once the surface is clean and dry, prime any bare spots with a suitable primer. You can use a zinc-based primer or an adhesion promoter, especially for plastic surfaces. You can spray or brush on the primer. If you are using a roller for the bed liner, it is recommended to also use a roller for the primer to achieve a more uniform texture.

Applying the Bed Liner:

Now, you can start applying the bed liner with the roller. Pour the bed liner coating into a roller tray. Use a 4-inch paint roller for better coverage and to fit into the contours of the surface. Dip the roller into the tray, rotate it to saturate, and then tap the roller to avoid applying excess product. Starting at the top or front of the surface, evenly roll the bed liner onto the prepared surface. Work towards the back, overlapping the roller strokes.

Applying Second Coat:

Allow the first coat to dry for at least 20 minutes to an hour before applying the second coat. For the second coat, start from the sides and roll towards the front or back, spreading in the opposite direction to ensure complete coverage. Allow the second coat to dry overnight, and if needed, apply a third coat in the same manner.

By following these steps, you can effectively apply a bed liner to plastic using a roller, creating a durable and skid-resistant coating.
