Bottom Paint Best Practice

Bottom Paint Best Practice

Top-quality bottom paint

One of the best ways to keep your boat in good condition is to have a top-quality bottom paint applied on a regular basis.

It will help prevent a number of problems that can lead to damage or loss

It will also improve fuel efficiency and help to protect your hull from oxidation. If you’re going to be storing your boat in the water for any length of time, it’s important to have a quality antifouling coating.

1. Prevent Delamination

Delamination of bottom paint is not only aesthetically annoying, but it can also cause structural damage to the hull. If left unchecked, delamination can lead to serious structural problems and even loss of your vessel

The best practice to prevent delamination of your boat's bottom paint is to choose the right type of paint for your needs. Using the correct bottom paint will help you increase efficiency throughout your season and reduce your maintenance costs.

In some cases, you may be able to avoid the problem entirely by making sure that your surface is properly prepared before painting it. Flaking, peeling and adhesion failure are all caused by improper surface preparation.

Delamination can occur in laminated composites, like cross-laminated timber (CLT). The separation of materials occurs due to weak bonding between the plies. Moisture content variations can also play a role in the development of delamination.

2. Prevent Oxidation

There are a few things you can do to keep your bottom paint bright and shiny. First, it’s important to avoid exposing the antifouling paint to excessive sunlight. This will cause the paint to fade over time and can make it look dull.

Second, it’s important to choose an antifouling paint that is safe for your water type. This will affect how the paint performs, particularly in saltwater environments.

Third, it’s important to choose a bottom paint that is corrosion resistant. This will help your boat last longer and save you money on repairs.

The most common bottom paint is copper-based. However, many people are choosing to go greener by using antifouling paints containing Econea, an environmentally friendly biocide that doesn’t contain copper.

3. Prevent Marine Growth

Antifouling bottom paint is designed to keep barnacles, weeds and algae from sticking to your boat’s hull. Marine growth can hinder fuel efficiency and engine performance.

The best way to prevent marine growth is by selecting the right bottom paint for your particular boat, water type and marina location. Ask other boaters what works well for them and take a look at their compatibility chart before you buy.

Most bottom paints contain a biocide, which means they’re able to kill off organisms such as slime, weeds and algae. However, most biocides use copper, which eventually leaches out of your boat and into the wider marine environment – this is why it’s important to find an eco-friendly bottom paint that doesn’t contain copper.

4. Prevent Corrosion

When it comes to preventing corrosion of your metal boat's hull, the best practice is to use a high-quality bottom paint. This coating protects the hull from the corrosive effects of marine growth such as barnacles, algae and slime.

There are a variety of bottom paints on the market to meet different needs and applications. The best bottom paint for your boat depends on where it is stored, water quality and a number of other factors.

Usually, antifouling bottom paints release a biocide over time that prevents marine growth from attaching to the hull. These biocides are commonly copper-based, but a growing trend in the industry is to use less harmful biocides with more eco-friendly alternatives.

There are several types of antifouling bottom paints available, including ablative and polishing. Ablative antifouling paints wear away when the boat is moving, whereas polishing bottom paints wear away at a controlled rate like a bar of soap over time, offering multi-season protection.
