How to Repaint a Pontoon Boat

Pontoon boats are flat, motorized forms of water transportation. They have a flat deck and benches that make them great for cruising with multiple people. Unlike the typical motorboat, pontoon boats float on two cylindrical, hollow pieces that are attached to the underside of the boat's platform. With proper maintenance, these boats can provide years of enjoyment. One maintenance option is repainting the pontoons. Much of the boat that would need paint consists of aluminum. Therefore, you will need to follow the steps for painting this material. Since you will be repainting, you will also need to prepare for a new coat with the old coat in mind.

Instructions

    • 1

      Clean the surface of the painted aluminum with dishwashing soap and a paper towel or clean rag.

    • 2

      Rub the surface of the painted aluminum with steel wool or 600 grit sandpaper wrapped around a sanding block. This will flatten any imperfections on the old paint and provide a rough surface to which the new coat of paint can bond.

    • 3

      Wipe the surface of the sanded paint with a tack cloth to remove any remaining dust.

    • 4

      Wipe the surface of the paint with rubbing alcohol and a rag to remove any dirt and debris.

    • 5

      Allow the painted aluminum to dry thoroughly.

    • 6

      Apply two to three coats of paint to the boat with a paint sprayer. A paint sprayer will provide a smoother finish than a paint brush for this particular surface. It is also faster than a paint brush or roller.

    • 7

      Allow the paint to dry for approximately two to three weeks so that it is fully hardened. Allowing for the paint to harden will prevent it from easily scratching, peeling or scuffing.
