Marine Coatings, Bottom Paint & Surface Prep

How to choose a marine coating system

Start with the substrate, existing coating, location above or below the waterline, immersion schedule and desired finish. Use compatible primers, topcoats, antifouling products, reducers and preparation materials from a system approved by the manufacturer.

Match coatings to repair materials

For cloth, mat, roving and reinforcement used before finishing, browse fiberglass and composite fabrics. For structural bonding, filling and localized repairs, compare epoxy adhesives.

Product-selection support

Tell us the boat or component material, current coating condition, water exposure, application method and desired finish. We can help narrow the options, but preparation, film build, overcoat windows and safety requirements must follow the product technical data.

Frequently asked questions

What is the difference between topside and bottom paint?

Topside finishes are designed for areas above the waterline. Bottom paints are formulated for immersed hull surfaces and may include antifouling performance. They are not interchangeable.

How do I choose antifouling paint?

Consider hull material, fresh or salt water, boat speed, use pattern, launch schedule and the existing coating. Confirm compatibility and local regulations before application.

Why is surface preparation important?

Cleaning, sanding, fairing and priming create the surface profile and adhesion needed for the coating system. Skipping preparation can cause early failure even when the finish coat is suitable.
