Corrosion on aluminum pontoons is a significant issue that can damage your equipment. It leads to costly repairs, shorter lifespan, and unhappy customers in the boating industry.
Preventing corrosion is crucial for reducing downtime and keeping pontoons in top condition.
In this post, we'll discuss the causes of corrosion, effective prevention methods, and essential maintenance tips to ensure long-lasting pontoons.
Aluminum pontoons are prone to corrosion due to several environmental and operational factors. The most common cause is galvanic corrosion, which occurs when aluminum comes into contact with dissimilar metals, such as steel or copper. This sets up an electrical reaction that accelerates the breakdown of aluminum. Other causes include stray currents from electrical systems, especially in marinas, which can travel through the water and cause corrosion. Chemicals like sulphates and weed control agents can also contribute to corrosion when they come into contact with aluminum pontoons. Saltwater exposure is another major factor that accelerates corrosion, especially in coastal regions where pontoons are frequently docked.
Inadequate maintenance can significantly speed up the corrosion process. Without regular cleaning and protective coatings, aluminum pontoons are left vulnerable to corrosion-causing elements. If pontoons aren’t properly stored, especially in wet or salty conditions, the corrosive effects of saltwater and chemicals can set in much faster.
Neglecting to inspect for early signs of corrosion, such as pitting or discoloration, also allows the problem to grow unnoticed, leading to more expensive repairs down the line.
One of the best ways to prevent corrosion is to apply copper-free antifouling paint. Copper-based paints can cause galvanic corrosion, but copper-free alternatives are safer for aluminum pontoons. This antifouling paint helps prevent marine organisms from attaching, which can cause further damage.
Regular cleaning of the float is essential to prevent corrosion. Start by removing surface dirt and salt with fresh water. Next, use a non-abrasive cleaner to avoid scratching the surface. For a deeper clean, there are products that can remove stains, oxides, and minor corrosion. It is important to dry the float with a microfiber cloth and prevent water spots.
Yes, a regular maintenance routine is vital. Ensure pontoons are cleaned after every use, particularly if they’re exposed to saltwater or chemicals. Regular inspectionsshould check for early signs of corrosion or pitting. Consider reapplying protective coatings at least once a year. The more proactive the maintenance, the longer the pontoons will last.
Avoid using abrasive cleaners that scratch the surface, as these can create microscopic pits where corrosion can begin. Additionally, never use copper-based antifouling paints on aluminum pontoons. They will react with the aluminum, causing corrosion to accelerate rather than prevent it.
If the corrosion is extensive or you are unsure of how to proceed, it's best to call a professional repair service. Signs you need professional help include deep pitting or significant damage that cannot be removed with DIY methods. Professional services can ensure proper repairs and prevent further issues.
To keep your pontoons in peak condition year-round, proper storage is key. During the off-season, store pontoons in a dry, sheltered area to avoid prolonged exposure to water and chemicals. Additionally, ensure drainage is properly managed to avoid water accumulation in and around the pontoons, which could contribute to corrosion.
Maintaining a shiny, polished surface not only improves the appearance of your pontoons but also reduces the buildup of pollutants, which can lead to corrosion. Use a buffing compound to restore the original finish. Regular polishing will ensure a smooth, shiny surface that is less prone to corrosion.
To keep aluminum pontoons from corroding, it's essential to understand the common causes, such as galvanic corrosion, stray currents, chemical exposure, and saltwater. Poor maintenance, like improper storage and lack of cleaning, can accelerate corrosion.
