Fold up Ladder

Dock ladders are susceptible to algae buildup and growth over time. Dock ladders commonly sit in water that is not circulated or aerated, which can breed the growth of algae. However, you can prevent and lessen algae buildup on your ladder.

Step 1 – Replace Old Ladder

The first step in preventing algae buildup on dock ladders is to replace a static ladder with a fold up or pull up ladder. The less time that the ladder spends immersed in water will lower the chances of algae buildup on the ladder. Remove the old ladder and install a fold up ladder. Then, keep the fold up ladder out of the water when not in use to prevent algae buildup. By pulling the ladder out of the water, it can dry and prevent algae buildup.

Step 2 – Paint the Ladder

Another step to prevent algae buildup on dock ladders it to paint the ladder with an anti-fouling paint. Anti-fouling paints work to prevent the growth and buildup of algae. Paint the entire ladder with anti-fouling paint to help prevent the growth of algae on the ladder.

Step 3 – Water Additives

Another option for reducing the algae on a dock ladder is to reduce the total amount of algae in the water. There are algae reducing products that reduce the algae growth in the water.
