Best Paint For Jon Boats: Ultimate Guide

When it comes to choosing the best paint for your Jon boat, there are several factors to consider, including the type of material your boat is made of, the environment in which you'll be using it, and the level of protection you need. Jon boats are typically made of aluminum, wood, or fiberglass, and each material has specific paint requirements. While generic paints can be used on multiple surfaces, specialized paints offer greater protection for specific materials. For aluminum boats, corrosion-resistant paint is essential, especially if the boat is used in saltwater. Wooden boats require marine-grade paint to protect against rot, while fiberglass boats benefit from paint with a glossy, clean finish. Proper preparation is key to achieving a great finish, so be sure to clean, prep, and repair your boat before painting.

Preparing your boat for painting

Preparing Your Jon Boat for Painting

Before you start painting your Jon boat, it's important to follow these steps to ensure a smooth and durable finish.

Choose a Suitable Work Area:

Select a spacious, sheltered, and dust-free location, such as a garage or outbuilding. Make sure the area is well-ventilated to minimise the impact of dust, fumes, and paint splatter. Protect your work area with dust sheets and plastic sheeting.

Prepare the Boat for Painting:

Balance the boat on supports, sawhorses, or trestles to access all areas. Clean the boat thoroughly, removing dirt, grime, salt buildup, and any peeling paint. Use a high-quality marine cleaner or degreaser, and a soft brush or sponge, to scrub the surface gently without scratching it. Rinse the boat with clean water to remove cleaning agents.

Inspect and Repair:

Look for any signs of rust, especially on metal parts, and use a rust remover or sanding tool to eliminate rust spots. Inspect for dents, cracks, or holes, and make a note of these areas for repair. Filling holes or cracks with a suitable filler designed for boats is essential before painting. Ensure these areas are well-sanded and sealed for a smooth finish.

Sand the Boat:

Start with a coarser grit sanding disc (40-80 grit) to remove old paint layers and smooth the surface. Progress to finer grits (100-220 grit) to refine and smooth out scratches. Remember to sand in the direction of the grain for wooden surfaces, and apply even pressure throughout. Pay special attention to edges and corners, which may require hand sanding for better precision.

Remove Dust and Debris:

Use a tack cloth or a damp cloth to remove any remaining dust after sanding. Ensure the surface is free of dust and debris before proceeding to the next step.

Tape and Cover:

Use painter's tape to cover hardware, windows, and any other areas you don't want to paint. Protect the flooring and surrounding areas with drop cloths or tarps to catch any paint drips or spills.

Choose the Right Primer:

Select a primer suitable for the material of your Jon boat. For fiberglass boats, choose a primer specifically formulated for fiberglass. For wooden boats, use a penetrating primer, and for metal boats, select a primer that prevents rust and adheres well to metal. Ensure the primer is compatible with your chosen paint type.

Apply the Primer:

Depending on the size of your boat and primer consistency, use brushes, rollers, or a sprayer for application. Apply multiple thin coats of primer rather than a single thick coat to achieve an even finish and faster drying. Lightly sand between primer coats with fine-grit sandpaper for a smoother final finish.

Cleaning the boat

Before painting your Jon boat, it is essential to clean it thoroughly. This step will ensure that the paint adheres properly and that the finished result looks smooth and professional. Here is a detailed guide on cleaning your Jon boat in preparation for painting:

• Start by pressure washing the boat to remove any dirt, grime, or foul. You can also use a combination of soap and water for this step.
• Next, use a solvent like acetone to ensure that all debris and residue are eliminated. This step will ensure that the surface is free of any contaminants that may interfere with the painting process.
• If there are areas of peeling paint, it is crucial to sand them down to ensure a smooth and consistent surface. This step will also help create a key for the new paint to adhere to.
• After sanding, use a soft-bristled brush to remove all the debris and dust from the sanding process. It is essential to ensure that the boat is entirely free of dust before proceeding.
• Once the boat is clean and prepared, allow it to air dry completely before moving on to the next step. Do not apply paint to a damp or moist surface, as this will affect the adhesion and quality of the paint.
• If your Jon boat is made of wood, be cautious when using power tools for sanding. It is important not to apply too much pressure, as this may damage the wood.
• Additionally, if your boat is made of aluminum, ensure that the surface is smooth before proceeding with the next steps.

By following these steps, you will effectively clean your Jon boat and prepare it for the painting process. Taking the time to clean and prepare your boat properly will ensure a high-quality and long-lasting paint job.

Making repairs

If your Jon boat is made of aluminium, it is important to get the aluminium smooth before applying a self-etching primer. You can use a product such as Hy-Poxy H-450 Alumbond 6.5 oz Aluminium Putty Repair Kit to smooth out the aluminium. Then, apply two coats of boat paint, allowing each coat to cure completely before flipping the boat to paint the other side. You can also add a clear coat on top for extra protection.

If your Jon boat is made of wood, you may need to fill in any dents or defects with wood filler or use a suitable technique to repair them. After sanding, you can apply a good primer before painting. Yacht varnish can also be used to protect and enhance the appearance of a wooden Jon boat, but it is important to note that a primer is necessary before applying varnish.

For fiberglass Jon boats, there are specific paint options that offer better protection and a more durable finish than generic paint. Wet Edge is a topside paint that can be used on the entire hull of a fiberglass Jon boat, providing an abrasive-resistant and flexible finish. Another option is TotalBoat Underdog boat bottom paint, which offers good protection in freshwater due to its copper biocide base.

Applying primer

Before applying the primer, it is crucial to prepare the surface of the boat thoroughly. This includes cleaning the boat to remove any dirt, grease, or wax and sanding down the existing paint surface to create a smooth base for the primer. It is important to ensure that the boat is completely dry before applying the primer.

When applying the primer, it is best to use a brush or roller designed for use with oil-based paints. It is recommended to apply thin coats of primer to ensure a smooth and even finish. The primer should be allowed to dry completely before moving on to the next step, which is painting the boat.

It is important to note that some paints, such as Aluma Hawk, combine primer and paint in one product, eliminating the need for a separate primer. However, if using a separate primer, it is crucial to follow the manufacturer's instructions and take the necessary safety precautions when working with paints and primers.

Painting the boat

Painting your Jon boat is a great way to revitalise its appearance and prolong its life. The process is relatively simple, but it requires the right materials and good preparation. Here is a step-by-step guide to help you get started:

Step 1: Preparation

Before you begin, make sure you have a suitable location for painting. Ideally, find a sheltered, spacious, and dust-free area, such as a garage. It is important to ensure that the area is well-ventilated, especially if you plan to use a spray gun or paint thinner. Prepare your boat by balancing it on supports, sawhorses, or trestles, which will allow you to access all parts of the boat.

Step 2: Cleaning

Start by thoroughly cleaning your boat to remove any dirt, grime, or peeling paint. You can use a pressure washer, soap and water, and acetone to get the job done effectively. Pay special attention to areas of peeling paint, as you will need to sand them down to ensure all the old paint is removed. Once you have finished cleaning, allow the boat to air dry completely before moving on to the next step.

Step 3: Repairs

Once your boat is clean and dry, inspect it for any dents, defects, or damage. Use the appropriate techniques or a suitable marine filler to make the necessary repairs. After making repairs, sand down the entire boat to create a smooth surface for the primer. Wash the boat again to remove any dust or dirt from the sanding process, and then let it dry.

Step 4: Priming

Priming your boat is an essential step, as it will help the paint adhere better and create a more even and durable finish. Choose a primer that is suitable for the material of your Jon boat, such as an aluminium-specific primer for aluminium boats. Apply the primer to the interior of the boat first and allow it to dry completely before priming the exterior.

Step 5: Painting

When your primer is fully dry, you can start painting your boat. It is important to build up the paint layer by layer, allowing each coat to dry completely before sanding it down to a smooth finish. Be patient and take your time with this process, as it will ensure a high-quality result. Depending on the type of paint you choose, you may only need one coat, but for added protection, consider applying multiple coats.

Additional Tips:

• If you are using a brush to paint, apply each brush stroke evenly for a smooth finish.
• Roller painting can help you finish the job faster, and it usually results in a finish similar to brush painting.
• If you are using a roller, have a few brushes on hand to reach the nooks and crannies that the roller can't access.
• Consider using a spray gun to apply the paint, as it will result in a quicker application and a more even finish.
• If you are painting a large Jon boat, you may need a helper to ensure the paint is applied rapidly and evenly.
• If you are painting a wooden Jon boat, consider using oil-based paints or glosses, which are traditional choices that can withstand the natural flexing and expansion of wood.
• For aluminium Jon boats, look for paints with anti-corrosion properties to protect against galvanic corrosion, especially if you plan to use the boat in saltwater.
