Roll-On Bedliner: Best Option For Aluminum Boats?

Boat owners have used roll-on bedliners on their aluminum boats, and the results have been mixed. Some boat owners have reported that the bedliner adheres well to aluminum and is extremely durable. Others have found that it causes corrosion under the bedliner, which then requires sanding and repainting. It is recommended that the aluminum surface be prepared properly before applying the bedliner to ensure adhesion. Some boat owners have also suggested using an etching primer or a self-etching primer before applying the bedliner for better results.

Pros and cons of bedliner for aluminium boats

Applying a bedliner to the interior of an aluminium boat has its pros and cons.

Pros

The bedliner can seal the boat, preventing leaks. It can also be used to fix existing leaks. It is also a versatile paint that can be applied to a multitude of surfaces, including aluminium.

Cons

Applying bedliner to aluminium may cause corrosion under the bedliner, and it may require sanding off and re-painting. It can also be abrasive and painful when bare arms and legs are rubbed against it. It can also get slick when wet, which could be a concern for a boat floor.

Some people have also reported that the bedliner can slow the boat down due to increased drag. It can also be expensive to apply.

Prepping aluminium for bedliner

When preparing aluminium for a bedliner application, it is essential to follow specific steps to ensure proper adhesion and a durable finish. Here is a detailed guide on prepping aluminium for a bedliner:

Cleaning and Degreasing

Start by thoroughly cleaning the aluminium surface to remove any grease, dirt, or debris. Use a solvent-based degreaser, such as U-POL WIPE6 or System 20, to ensure the surface is free of any contaminants. This step is crucial as it ensures the bedliner will adhere properly to the aluminium.

Abrading the Surface

Once the surface is clean and dry, abrade it with sandpaper to create a rough texture that will help the bedliner stick. Use 180-grit sandpaper to scuff the aluminium, and consider using a DA (disc sander) for more aggressive abrasion. After sanding, wipe the surface clean with a tack cloth to remove any dust or residue.

Priming (Optional)

While some people choose to apply a primer before the bedliner, others suggest that it may not be necessary. If you decide to prime, use a self-etching primer specifically designed for aluminium, such as Rust-Oleum self-etching primer. Apply the primer according to the manufacturer's instructions, and allow it to dry completely before proceeding to the next step.

Final Surface Preparation

Just before applying the bedliner, give the aluminium surface a final abrasion to ensure optimal adhesion. Use 400-grit sandpaper and lightly scuff the surface. This step helps create a stronger bond between the bedliner and the aluminium.

Choosing the Right Bedliner

Select a bedliner product that is suitable for use on aluminium. Some popular options include Raptor Liner, Herculiner, and Rust-Oleum Truck Bed Liner. Follow the specific instructions provided by the manufacturer of your chosen bedliner for the best results.

Application

Follow the directions that come with your chosen bedliner for application instructions. Some products may require multiple coats for optimal coverage and durability. Allow sufficient drying and curing time between coats and before using the aluminium surface.

Remember, proper preparation is key to achieving a long-lasting and durable finish when applying a bedliner to aluminium. Take your time with each step, and don't skimp on the preparation process to ensure the best results.

Spraying vs rolling on bedliner

When it comes to applying a bedliner, there are two main methods: spraying and rolling. While rolling can be a cheaper option, it often results in a less consistent application and may not provide the same level of protection as spraying.

Spray-on bedliners are a popular choice among truck owners due to their durability and long-lasting protection. They are custom-fit to your specific truck, ensuring maximum protection. However, they can be expensive and time-consuming to apply, requiring special equipment and training. Spray-on bedliners also require meticulous surface preparation to ensure proper adhesion and avoid overspray and adhesion issues.

On the other hand, roll-on bedliners are more affordable and can be applied as a DIY project. They offer a quick and easy solution, but may require multiple applications for adequate protection. While rolling can be more challenging to apply evenly, it is still important to follow the manufacturer's instructions for proper application.

When deciding between spraying and rolling on a bedliner, it is important to consider the level of protection needed, the time and cost involved, and the application process. Spraying provides a more consistent and durable finish, while rolling can be a more cost-effective and accessible option.

Additionally, it is worth noting that bedliner products can be applied to aluminum boats as well. However, there are some concerns about corrosion under the bedliner, and it may require sanding and repainting. Some people prefer the "roll-on" option for boats as it is less rough on bare feet and easier to clean than spray-on options. It is recommended to avoid applying roll-on coatings on the hull of the boat as it may create additional drag, and it can get slick when wet, which could be a safety concern.
