The Buyer’s Guide
Painting a boat is somewhat different from painting other products. It is a very responsible and important task. The fact is that the boat is constantly working in specific conditions. Therefore, the coating must be both stable and durable.
Before realizing this idea, read the following tips.
What paint is the best?
Large vessels cannot be finished with only one type of paint. One paint goes above the waterline, and the other is applied below the waterline. But as a rule, the aluminum boat can be finished with one paint as its size is not big. The choice of paints is quite large, therefore, it is recommended to study in detail the properties of the paint, and it is necessary to follow safety precautions when carrying out general work. You can use the following types of coating:
- Oil-based paints
These are paints and varnishes based on drying oils. All oil paints and enamels contain pigments that give them color. You can use only those paints which do not contain lead as a pigment. Oil paints with lead will destroy aluminum. Any other pigment in the paint will not damage the boat. It is better to choose enamel for the painting of the boat, it is stronger and has a glossy finish. Apply oil paints only after a primer.
- Epoxy paints
In recent years, epoxy-based paints have become very popular. Epoxy paint usually serves as a primer layer, but it can also be used as a finishing coating for the vessel. Note, this paint will not work on boats previously painted with oil paints. It is usually enough to apply it in a single layer. Painting is carried out in small areas. Epoxy paint is toxic and requires very careful use.
How to determine the compatibility of paints?
If you decide to repaint your boat, you must know what paint was originally used for it. Old and new paints must be compatible. It is easy to find out if you carry the following experiment:
- Soak a small piece of cloth with solvent.
- Attach it to a boat with a larger piece of the plastic cover.
- Seal the edges of the with sealing tape.
- A day later, check if the paint under this cover is bubbled or not. If it is not affected, you can start treating it with a new finish.
How to prepare a boat for painting?
The success of the boat painting depends on proper surface preparation. Therefore, you should thoroughly prepare the surface, by following these simple steps.
- Clean your boat from dirt, oil, peeling paint, and fouling below the waterline. Do not forget to repair areas with damages if necessary. Corrosion somewhere on the vessel will force you to postpone painting until the repair is complete.
- Remove old paint. When working on major repairs of a metal boat, first completely remove the old coating using a synthetic cord-brush or an old paint remover. It is better to clean the surface gradually, covering small areas with a cloth soaked in a solution and tightly covering the top with polyethylene. When scraping off old paint, be careful not to damage the protective layer of the metal.
- After removing the paint, thoroughly wash the boat from the acid and paraffin that are usually available in the paint remover. Wash the boat 2-3 times using the appropriate cleanser. Even a small handful of dust can cause big trouble while painting.
- Spackle uneven areas. Since the hull of the boat is subject to vibrations and deformations, it is preferable to choose a specialized material to restore its surface.
- And only then you can pass to painting.

Lastly, if your boat is exposed to regular wear and tear from hitting docks or rocky bottoms, then bottom paint can help provide additional protection. Ultimately, it’s up to you as the boat owner to decide whether or not you feel bottom paint is necessary for your vessel.
