How to Paint a Boat Trailer

how to paint a boat trailer

Due to the high price of a boat trailer, many cannot and have no intention of purchasing a new one. The smart decision should be to buy a used trailer that is still in good condition. Then, to give the trailer a new look, we can just paint it the color we want.

Indeed, choosing the right paint and starting with the task might sound intimidating for some new boaters. Therefore, in this blog post, we will go over the process of painting a boat trailer and provide some tips on how to make it look its best.

How to Paint your Boat Trailer

What to Prepare:

  • A power washer or garden hose
  • Sandpaper (120-grit)
  • A pair of gloves and a face mask – Make sure you put them on before sanding and priming your trailer
  • Primer (oil-based or latex)
  • Paint (oil-based or latex)
  • Painter’s tape
  • Drop cloths
  • Paint

A few different types of paint are usable on boat trailers, but the best type to use is marine-grade paint. It is formulated to withstand the harsh conditions that boat trailers are exposed to, such as salt water and UV rays

Besides, choose the quality paint with a long drying time of about 1 hour and a curing time of 5 days. Such a product should be long-lasting, resistant to chipping, abrasion, and quick fading

Step 1: Prepare the Surface

The first step is to clean the surface of the boat trailer. If you use a power washer, start with the lowest setting and work your way up.

If you are using a garden hose, scrub the surface with a brush to remove any dirt or grime. Once the surface is clean, let it dry completely before moving on to the next step.

Step 2: Sand the Surface

Once the surface is dry, you will need to sand it down. This preparation step will help create a smooth surface for the primer and paint to adhere to.

Be sure to use medium-grit sandpaper (120-grit) and sand in the direction of the grain. Once you have finished sanding, wipe down the surface with a tack cloth to remove any dust.

Step 3: Apply Primer

The next step is to apply primer to the boat trailer before painting it. Primer helps the paint stick to the surface and will also provide a base coat of color.

If you are using an oil-based primer, be sure to use a brush designed for oil-based paints. For latex primer, any type of brush will work.

Apply the primer in thin coats, letting each coat dry completely before applying the next.

Step 4: Paint the Boat Trailer

After the primer has had time to dry within at least 60 minutes, it’s time to start painting!

It is recommended to paint your trailer using a roller or a paint sprayer for even application.

It would take much longer and require much effort and dedication if you use a brush.

Just like with the primer, apply the paint in thin coats, letting each coat dry completely before applying the next.

Step 5: Let it Dry

Once you have finished painting, let the boat trailer dry entirely before using it. This can take anywhere from 24 to 48 hours to dry and a week or so to cure.

Do not disturb the trailer while it’s curing. And that’s it! With these easy steps, you can successfully paint a boat trailer on your own.

How do you Paint a Rusty Boat Trailer?

If your boat trailer is starting to show signs of rust, it’s important to take action to prevent the problem from getting worse. Painting your boat trailer is a great way to protect it from further rusting and damage.

Step 1: Clean the Rust

To paint a rusty boat trailer, you’ll need to start by cleaning off all the rust.

  • If the rust is only superficial, you can remove it by sanding the affected area with medium-grit sandpaper
  • For more serious rusting, you’ll need to use a wire brush or power washer to remove it

Step 2: Prime and Paint the Trailer

Once the rust is gone, you can proceed with priming and painting your boat trailer.

When painting a boat trailer, it’s important to use paints formulated for metal surfaces to give you the best results.

Look for a paint labeled “rust-resistant” to ensure that it will stand up well to the elements. You’ll also want to make sure that you choose paint compatible with the type of primer you used. If you’re not sure, ask a salesperson at the hardware store for help.

Once you have your paint and primer, you can start painting your boat trailer.

What type of Paint should you use on a Boat Trailer?

Boat trailers are exposed to many elements that can cause wear and tear. That’s why it’s important to use the right type of paint to protect your trailer from rust and other damage.

Two types of paint are commonly used on boat trailers: oil-based and water-based.

  • Oil-based paint is more durable and offers better protection against the elements. Still, it is also more difficult to apply
  • Water-based paint is easier to apply but doesn’t offer as much protection

When choosing paint for your boat trailer, consider how often you’ll be using it and what kind of conditions it will be exposed to.

  • If you live in a wet climate or plan on using your trailer in saltwater, oil-based paint is a better option.
  • Water-based paint will be sufficient if you’re only using your trailer occasionally or in milder conditions.
  • If you’re looking for durable paint that will resist corrosion, you should look for one specifically designed for boat trailers. These paints typically contain zinc oxide, which helps protect against salt water and other corrosive materials.
  • You’ll also want to make sure that the paint you choose is compatible with the type of metal your trailer is made from.
  • If you don’t want to use a primer, you can choose a paint that already has one built-in. These paints will typically have better coverage and be more durable than those without a primer. However, they are usually more expensive as well.


Painting a boat trailer can be a daunting task. But with the proper preparation and the correct steps, it can be an easy process. Follow these simple tips, and you’ll have your boat trailer painted in no time.
