Marine Seam Sealer & Fairing Compound

Understanding Boat Fairing Compounds and Marine Sealants

Whether restoring a classic cruiser or prepping a racing yacht for competition, achieving a smooth surface is essential for a pristine-looking boat. That's where boat fairing compounds and marine sealants come in. At Fisheries Supply, boaters can shop a full range of marine fairing compounds and seam sealers designed to enhance durability, appearance, and hydrodynamics.

What is Boat Fairing?

Boat fairing is the process of correcting surface imperfections on a hull or deck to create a sleek, even profile. This step is vital for optimal paint adhesion and hydrodynamic performance. Using a fairing compound for boats helps restore smooth lines and prepares the substrate for a high-quality finish. For gelcoat touch-ups, consider a specialized fairing compound for gelcoat.

Types of Fairing Compounds

Fisheries Supply offers high-performance polyester fairing compound and epoxy fairing compound solutions to suit every project:

Polyester Fairing Compound

• Ideal for use above the waterline
• Fast-curing and easy to sand
• Perfect for cosmetic repairs and spot fairing
• Cost-effective option for light-duty needs

Epoxy Fairing Compound

• Designed for use above and below the waterline
• Delivers superior adhesion, strength, and durability
• Recommended for structural or extensive repairs
• Pairs well with epoxy-based primers and coatings

Yacht fairing, especially caulking superyacht fairing, demands a flawless application. That's why professional-grade marine fairing compounds are specifically engineered for precision work on larger vessels.

Marine Sealants

In addition to fairing, sealing seams is critical for waterproofing and longevity.

These marine sealants:

• Form a watertight barrier that prevents water intrusion
• Guard against mold, rot, and corrosion from trapped moisture

Choosing the Right Fairing Compound for Your Boat

To find the best boat fairing compound, consider the following:

• Whether the application is above or below the waterline
• The scale of the fairing or repair job
• The type of hull construction—fiberglass, wood, or metal
• How much time you have for curing, sanding, and recoating

Fisheries Supply's product specialists can help you identify the right fairing boat solution based on your project scope.

FAQs

What is the difference between polyester and epoxy fairing compounds?
Polyester compounds are quick-curing and cost-effective, suitable for above-waterline cosmetic repairs. Epoxy compounds offer superior strength and are ideal for both above and below waterline applications.

Can I apply gelcoat directly over fairing compound?
Not directly. Apply a compatible epoxy barrier coat or primer over the cured fairing compound before applying gelcoat.

How do I apply fairing compound?
Clean and sand the surface. Mix the compound according to the instructions, apply it with a spreader, and allow it to cure before sanding smooth.
