Best Paint For Boats

Using the best paint for boats is a simple way to boost the vessel’s curb appeal as well as protecting it against galvanic corrosion and marine growth.

It is important because the moment the boat leaves the shelter of the builder’s yard to the water, it’s vulnerable to electrolysis, galvanic corrosion, and fouling.

The paint is the only dependable line of defense that shields the raw vessel against ultraviolet degradation and hydrolysis. So, it’s crucial to paint your boat.

Why Should You Paint Your Boat?

Best Paint For Boats

There is just something pleasantly weird about the boat (I can’t really place my finger on) that awakens the adventurous side in us.

Whether you are scuba diving to mining the sails and fishes or exploring new beachfront, there is something incredibly freeing about cruising on the open water that lures you to visit over and over again.

And, one day you returned from an exciting ride only to see the color of the vessel fading, begun to erode or has been covered with marine growth.

Whatever the case may be, seeing your only escape to the water (boat) turning bad is very depressing.

It sounds obvious that forgoing the boat to getting a new one is a crazy decision you only get to make when you’re swimming in money.

But, using the best paint for boats is the quickest route to see your hull in good condition and back to the sea again.

What to Look for When Buying Boat Paints

boat paint reviews

If you lay hands on the appropriate product that will serve your needs, you need only two things: identify the problem and choose the paint designed to solve that particular problem.

Identify the project you have in Hand

There are hundreds of marine paints in the market with different functionalities. And, you can easily get lost in the whirling abundance. So, it’s critical to know why you are buying the boat paint.

Are you touching up scratches, minor dents, improving the appearance of your watercraft to resist UV and weathering, or are you only interested in fighting against exposure to dirt, barnacles, algae, and micro-organisms?

Knowing the reason behind buying a boat paint will lead you to the appropriate product.

The Type of Paint

There are two different types of marine paint you can choose from to handle the job on the table.

Let’s look at them below.

Above-waterline marine paint

These paints are also known as topside paints. You can only apply them anywhere above the waterline of your boats, such as the sides of the hull, deck, and interiors.

They are oil-based formulas and are suitable for fiberglass, metal, and wood surfaces.

Topside marine paints have a high-performance for color retention, durability, flexibility, and UV resistance.

Thus, making them the best bet for minor dents, touching up scratches, as well as adding curb appeal because they are resistant to cracking, peeling, and chipping.

Below Waterline Marine Paint

These underwater hull paints are often called bottom paints or anti-fouling paints. They prevent the growth of organisms such as barnacle and algae that attach to the hull.

When repairing dent and dings below the waterline, bottom paint is a go-to option. Choose flat marine anti-fouling products. They slowly release copper, which helps prevent the build-up of marine growth.

However, without the bottom paint, these species can ruin the fabric of the vessel to the degree that water can sip in, and the boat will eventually sink.

Frequently Asked Questions

Does bottom paint devalue a boat?

Bottom paint has its merit and demerits, more precisely if there are many layers. Although, the only drawbacks you get to experience after using bottom paint are a liability in cost and performance.

There is a saying that maintenance is a drag on your time and your finances. And, that is the bitter truth in this case. Bottom paint will slow your boat down and eat up fuel pretty much.

You will be locked in a cycle of maintenance. Many boaters replace their antifouling annually – it’s not a once-in-a-while job. You will have to carter for it.

The worst part? Most boatyards are banning boat owners from rejuvenating their boats by themselves. So they could control the risk factors and insurance, which requires another cost on your path.

What happens if you don’t bottom paint your boat?

Cruising around with a naked boat is prone to barnacle, weeds, algae, and slime build-up. And when it does, it can drastically affect the vessel’s speed, performance, and durability for an extended period.

On the other hand, bottom paint will help prevent the growth of all these organisms that won’t hesitate to attach themselves to the hull.

How long can a boat stay in the water without bottom paint?

First and foremost, it isn’t advisable to leave an unpainted boat on the water – whether on fresh and saltwater.

I have seen a boat covered in barnacles in a matter of weeks, although location plays a vital role too. If the water is warmer, it will accelerate the growth of the Asian clams, zebra mussels, and other small organisms.

I wouldn’t dare put my precious boat in the water without bottom paint, although a couple of days would be fine.

Do freshwater boats need bottom paint?

It’s imperative to use bottom paint for your freshwater boat, especially if you are leaving it in the water overnight.

Your boat may not accumulate barnacles quickly, but in the long run, it can grow a healthy beard of algae slime and plant.

What kind of paint do you use on a fiberglass boat?

polyurethane type paints
The best paints available, in terms of durability and gloss retention, are the two-part polyurethane type paints. These paints are very thin, requiring multiple coats. However, they chemically harden to a very durable finish that will last for many years.

What is the best kind of paint to use on fiberglass?

Acrylic Latex

Acrylic paint adheres well to fiberglass, overcoming one of the main challenges to painting this material. Acrylic paint is less likely to crack and blister, and will hold up well to cleaning. This water-based paint is easy to apply, and contains fewer chemicals, so is more environmentally friendly.

Gel coat is the most common surface coating used in the fabrication and repair of fiberglass reinforced products. Gel Coat is a specially formulated two-part polyester resin that is designed to be the first layer of resin applied in a mold when making a polyester or vinyl ester composite part.

Can you paint over gelcoat on a boat?

If the gelcoat is in good condition with no major cracking or crazing, the job is relatively straightforward—clean and prepare the surface, apply an epoxy primer, sand the primer, remove the sanding residue and then apply the topcoat.

Can I spray paint a fiberglass boat?

Painting fiberglass boats isn’t really much different from painting wood boats, except for the type of paint you’ll use and a few details in the prep and application. We should note that the very best finish can be attained by professionals who spray on the paint, rather than applying it with a brush and roller.

Can you use automotive paint on a boat?

When using car paint, you can paint over with urethane topcoat in cases of a smooth gel coat. While the paint isn’t as robust as a gel coat, it’s a viable choice for enhancing the appearance of an older boat. If you have a faded boat, the best option is to sand it with ultra-fine sanding paper.

What is the difference between paint and gelcoat?

What is difference between gel coat and paint? Gelcoat is usually much thicker than paint and is engineered to protect the underlying fiberglass as well as provide a smooth shiny appearance. Paint is thinner and typically much easier to apply.
