Discover The Best Bottom Paints In The Market
It is important to choose the right paint for your boat's bottom to protect it from water damage. This is for several reasons. The paint is called "ablative" or "anti-fouling". Regular boat maintenance should include reapplying new coats.
There are many types of boat bottom paints available, which can vary in price and durability. It is important to know the main types of bottom paint and to follow the tips to get the best results on your boat.
Different types of bottom paint for boats
There are five types of boat bottom pain: ablative, hard mod epoxy paints; thin film bottom paints; water-based antifouling sprays; and aluminum bottom paints.
Paints with a Bottom Paint
The relative paint starts to wear down slowly (i.e. The "ablates" are removed slowly, leaving behind a layer of biocides. This makes it difficult for algae, barnacles, and other marine growth to attach to the boat's hull.
Epoxy paints that can be hard modified
These paints resist abrasion and have a higher copper content. They are better suited for boats that are often in the water all year.
Thin Film Bottom Paints
Thin film bottom colors dry quickly and can be applied quickly in multiple coats. They are slick with a PTFE coating and at least one biocide to prevent marine growth. This type of paint is often used by racing sailboats.
Water-based antifouling paints
Water-based antifouling sprays are more environmentally friendly and can be applied with less harmful chemicals. These paints are easier to use in your garage or driveway and have a lower environmental impact.
Aluminum Boat Bottom Paints
Bottom paints that are specifically designed for aluminum boats can be used to prevent galvanic corrosion.
What is Antifouling?
Is your boat getting slower? Perhaps your hull is covered in algae and barnacles, which can cause frictional drag to increase. Manual cleaning of a submerged vessel by divers can prove costly and time-consuming. It can be difficult to pull the vessel out of the water. A fouled boat can cause up to 40% fuel consumption, reduce speed, and pose other hazards to safety and the environment.
What is biofouling?
As they reduce efficiency, wear and tear, and cause corrosion of key components, barnacles, mussels, and other marine growth pose a problem. Biofouling can get into your boat, in your pipes, and inside your water intakes. It can cause blockages and even complete destruction.
What are antifouling agent?
There are many ways to stop this problem: electrolytic systems (that use DC current to stop marine life from flourishing), chemical treatments/dosing, which can be harmful to the environment and corrosive/unhealthy to the ship and its owners), ultrasonic waves (high-frequency wave that can reduce biofouling substantially) and electro-chlorination (which uses seawater to make chlorine that kills marine growth).
What are the Best Boat Bottom Paints?
Your application and the environment will determine which bottom paint is best for your boat. So do your research before you dive in. There are many anti-fouling options available to modern boats. These systems can help prevent marine growth or biofouling at different locations. The marine industry is currently working to develop new non-toxic antifouling methods and solutions. This can often mean that biocides and copper are being replaced by less toxic alternatives. We've collected the top options in each category.
1. SLIPS, Dolphin, and Bottom Paint
Advanced surface coatings such as the SLIPS (r) Dolphin (tm) Bottom Paint, previously known as "Foul Protect" or SLIPS N1x Marine Paint, are another great option.
SLIPS Dolphin, a new type of marine bottom paint that is suitable for commercial and recreational boats of all sizes, solves the problem of biofouling. It makes a smooth, slippery surface that fouling cannot attach to. It lasts for multiple seasons, so you don’t need to paint your boat every year. Unlike many other products, SLIPS Dolphin does not contain biocides. It is also environmentally friendly.
2. Hydrocoat Eco Paint by Pettit
Pettit Hydrocoat Eco, a water-based copolymer ablative base paint, wears away over time. It creates a new surface and prevents paint buildup. Hydrocoat Eco is the most potent, metal-free biocide Econea. It protects the hull and minimizes marine life's negative effects. The formulation offers multiple seasons of protection thanks to its slime-fighting agent. This paint is easier to use because it has a water base. It can be washed with soap and water. You can thin it with water and reduce the VOCs. It doesn't need to be sanded between coats and will last for multiple seasons, depending on the environmental conditions. Copper-free formula can be used on any substrate, including steel, aluminum and GRP. The boat can be removed from the water without affecting its effectiveness.
3. Interlux Antifouling Trilux 33
Interlux offers a range of antifouling paints that are compatible with aluminum boats. These paints include a "Biolux" additive that improves boat performance by controlling slime, preventing fouling and is available in bright, clean colors.
4. Clearline by ElectroSea
ElectroSea is a world leader in marine-growth prevention systems and recently launched the Clearline system. It contains patent-pending technology that helps prevent marine growth and barnacles in raw-water lines. The system uses electro chlorination technology to make sure that algae, barnacles and biofilm cannot survive. This allows for less boat maintenance, extends equipment's life, and reduces harmful chemicals required to perform traditional acid-descaling practices.
5. JD Select Ablative Bottom Paint Antifouling
JD Select's water-based formulation is more eco-friendly than traditional solvent-based bottom coats. However, this does not compromise its effectiveness. The medium copper content keeps barnacles and slime at bay in low- to moderately fouling waters. Often, it can be applied with only one coat. JD Select can dry in as little as two hours depending on the temperature.
