Marine Primer & Undercoat Paint

Marine Primer and Undercoat Paint for Your Boat

As a boat owner, you understand the importance of protecting your vessel. A high-quality marine primer is the first step in ensuring a durable and long-lasting finish. At Fisheries Supply, we offer a wide range of marine primers from top brands, like Alexseal Yacht Coatings, Interlux, Pettit and Awlgrip.

Understanding Marine Primers

Marine primers are specialized coatings that create a durable interface between the gelcoat and the antifouling paint. Boat primers reinforce the adhesion of the antifouling paint, ensuring that it stays in place and continues to protect your boat from marine growth and corrosion. Unlike antifouling paint, boat primer paints are formulated to withstand the constant exposure to water and salt.

Types of Marine Primers

• Epoxy Primers: Epoxy primers are a popular choice among boat owners due to their durability and ability to create a strong bond with the antifouling paint. Marine epoxy primers are particularly effective in preventing osmosis, which can cause damage to the boat's hull. Epoxy primers are available in a range of formulations, including those specifically designed for aluminum hulls.
• Alkyd Primers: Alkyd primers are another popular option, known for their ease of application and affordability. They are a good choice for boat owners who want a high-gloss finish without breaking the bank. However, they may require more frequent reapplication than epoxy primers.
• Polyurethane Primers: Polyurethane primers are known for their hardness and scratch resistance, making them a great choice for boats that will be used in tough conditions. They are also resistant to UV rays, which can be a good application above the waterline on hulls and decks.

Choosing the Right Marine Primer for Your Boat

When selecting a marine primer, it's essential to consider the type of paint you will be using on top of the primer. Some primers are designed to be used with specific types of paint, so itis important to choose a primer that is compatible with your chosen paint.

• Undercoat Paint: Undercoat paint is a specialized type of primer designed to be used on metal hulls. A marine metal primer provides a smooth surface for the application of antifouling paint and helps to prevent corrosion.
• Antifouling Primers: Antifouling primers contain a biocide that is designed to slowly release as the paint wears off, preventing marine growth from attaching to the hull. They are a must-have for boats that will be in the water for extended periods.
• Non-Sanding Primers: Non-sanding primers are designed to be applied without sanding the surface first. They are a convenient option for boat owners who want to avoid the hassle of sanding.

Applying Marine Primers

Applying marine primers requires some preparation and planning. It's essential to ensure that the surface is clean and free of any debris or old paint. Once the primer is applied, follow the manufacturer's instructions for drying time and reapplication.

When buying marine primer and undercoat paint, you can consider things like:
Wood density: Will the primer raise the grain on raw wood, especially softer woods like pine?
Protection: Will the primer protect against corrosion, wood rot, osmosis, and moisture penetration?
