What You'll Learn

Preparation: Clean and scuff the plastic surface
Before applying a rhino liner to a plastic surface, it is important to prepare the surface by cleaning and scuffing it. This process will ensure that the liner adheres properly and results in a durable and long-lasting finish.
Begin by removing any hardware or components that are not meant to be coated with the rhino liner. This includes items such as bed bolts, tie-downs, and tailgates. By removing these parts, you can ensure a clean application and avoid any issues that may arise from spraying over them.
The next step is to thoroughly clean the plastic surface. Use a suitable cleaning agent, such as brakleen, applied to a rag rather than directly onto the plastic. This step will remove any dirt, grease, or gloss from the plastic, creating a pristine surface for the rhino liner to adhere to.
Once the surface is clean, it needs to be scuffed to create a rough texture that will enhance the adhesion of the liner. This can be done using sandpaper, steel wool, or a specialised tool designed for scuffing. For best results, use a grit of 60 or 100 when sanding the plastic surface. The scuffing process should be thorough, covering the entire area that will be coated with the rhino liner.
After scuffing, it is important to ensure that any residue or dust from the scuffing process is removed. Use a clean rag or brush to wipe down the surface, ensuring it is free of any debris that may interfere with the adhesion of the rhino liner.
By following these preparation steps, you will create an optimal surface for the rhino liner to adhere to, resulting in a strong and durable finish that will protect your plastic surfaces.

Priming: Use an adhesion promoter or primer for best results
When applying a rhino liner to plastic, priming is an essential step to ensure proper adhesion and long-lasting results. Here are the detailed steps and recommendations for the priming process:
Firstly, it is important to select the right primer or adhesion promoter for the job. While some products may not require a primer, using one is highly recommended for the best adhesion and durability. Choose a primer that is specifically designed for use with plastic surfaces or challenging areas that are difficult to sand. This will ensure that the rhino liner adheres securely to the plastic surface.
Before applying the primer, it is crucial to prepare the plastic surface thoroughly. This preparation process involves cleaning the plastic to remove any dirt, grease, or debris. It is recommended to use a suitable cleaning agent, such as brakleen, being careful not to leave it on the plastic for too long, as it can damage certain plastics. After cleaning, ensure that the plastic surface is completely dry before proceeding to the next step.
Once the surface is clean and dry, it needs to be roughened to create a better adhesion surface for the primer and rhino liner. This can be achieved by scuffing the plastic with sandpaper, steel wool, or grit paper. It is important to scuff the entire surface evenly to create a consistent texture that will allow the primer and liner to adhere properly.
After the surface has been prepared, it's time to apply the primer or adhesion promoter. Carefully follow the instructions provided with your chosen primer product. Typically, the primer will be applied in a thin, even coat across the entire surface. Ensure that you are working in a well-ventilated area and wearing the appropriate protective gear, including gloves and a respirator, to safeguard against any fumes or chemicals.
Allow the primer to dry completely according to the manufacturer's instructions. Depending on the primer used, it may require several hours or even overnight drying time. Once the primer is dry, you can proceed with the next steps of applying the rhino liner, following the specific instructions for your chosen liner product.
By following these priming instructions, you will achieve better adhesion and a more durable finish when applying a rhino liner to plastic surfaces. Remember to work in a well-ventilated area, wear protective gear, and always refer to the specific instructions provided by the manufacturers of your chosen primer and liner products.

Application: Spray, roll, or brush on the Rhino liner
Spraying, rolling, or brushing on a Rhino liner is a detailed process that requires careful preparation and execution. Here are the steps to follow for a successful application:
Preparation
Before applying the Rhino liner, it is crucial to prepare the surface thoroughly. Start by removing the tailgate and any hardware in the area to be sprayed, such as bed bolts and tie-downs. This ensures a clean application and easy access to the truck bed. Next, use masking techniques to protect the areas you don't want to coat. Outline the desired area with wire tape and then use masking tape and paper or plastic coverings to mask off the tailgate, truck bed, and other exposed areas.
Surface Treatment
To ensure proper adhesion of the Rhino liner, you must prepare the surface. Scuff the paint across the truck bed and tailgate using a scuffing tool or sandpaper. This creates a rough texture that enhances the adhesion of the liner. Clean the surface thoroughly to remove any dirt, debris, or gloss. Use a suitable cleaner, such as brakleen, but be cautious as certain chemicals can damage plastics if left on for too long.
Application Techniques
Now, you can apply the Rhino liner using your chosen method: spraying, rolling, or brushing. For spraying, use a spray gun or aerosol spray can. Ensure the spray is directed only at the desired areas, following the masking outline. If rolling, pour the liner into a roller tray, saturate the roller, and evenly roll it onto the surface, working from the top of the truck bed downwards. For brushing, use a suitable brush and follow the manufacturer's instructions for the best technique.
Multiple Coats
Depending on the product and your desired level of protection, you may need to apply multiple coats of the Rhino liner. After applying the first coat, allow it to dry for at least 30 to 60 minutes. Once dry, apply the second coat, following the same application technique as before. For the best results, follow the specific instructions provided with your chosen Rhino liner product.
Final Steps
Once the final coat has dried, carefully remove the masking tape and coverings. Pull the wire tape away perpendicularly to the surface to achieve a neat and clean edge. Finally, reinstall the tailgate and any removed hardware. Your truck is now ready to use with its newly protected surface. Remember that attention to detail is crucial throughout the process to ensure a successful and long-lasting Rhino liner application.
