TotalBoat TotalProtect Epoxy Barrier Coat System
The TotalProtect system is a two-part epoxy primer and barrier coat designed for both above and below the waterline, with strong blister prevention for gelcoat and effective protection for underwater metals. Best for boats needing a robust barrier before topcoats or repairs to fiberglass surfaces. It is particularly suitable for vessels exposed to harsh marine environments.
Best for: boaters performing gelcoat blister repair or requiring a reliable underwater barrier. Potential limitation: as a two-part epoxy, it demands careful mixing and precise application conditions for best results.
TotalBoat Wet Edge Topside White
TotalBoat Wet Edge White is a durable, high-gloss marine polyurethane designed for above-waterline topside surfaces. The 1-part formula offers flexible application methods—brush, roller, or spray—delivering professional results with strong color and gloss retention. It resists fading, cracking, and peeling, making it a solid choice for long-lasting beauty on power and sailboat hulls, as well as RV exteriors and trim.
Best for: owners seeking a simple, one-part system with excellent gloss and ease of application for above-waterline surfaces. Limitation: it should be used above the waterline only and may require re-coats for heavy wear or sun exposure over time.
TotalBoat Wet Edge Topside Whaler Blue
This TotalBoat Wet Edge option in Classic Whaler Blue provides the same durable, high-gloss polyurethane finish as the White variant, with color selection to match classic vessel aesthetics. It’s easy to apply and resists fading, cracks, and peels, making it suitable for multi-season beauty on hulls, trim, and exterior features. Best for: boaters wanting a traditional blue topside with robust protection.
Caution: like all topside paints, prep and surface condition influence final color and adhesion; ensure surfaces are properly cleaned and primed as needed.
TotalBoat Wet Edge Topside Sea Foam
Sea Foam matches the Wet Edge line’s durability and ease of application, offering a versatile, high-gloss finish for topside surfaces. The 1-part formula can be rolled, brushed, or sprayed, and is designed to resist fading and cracking. Best for: boaters needing a reliable, multi-season topside finish with color variety for above-waterline use. Limitation: use only above waterline to maintain warranty expectations and performance.
Samurai 2K Spray Paint for Marine
Samurai 2K Spray Paint for Marine uses a two-component aerosol system, combining hardener and paint in one can for a durable polyurethane marine finish. Best for quickly coating hard-to-reach areas or performing fast repairs with a professional-looking result. It offers stronger UV protection and chemical resistance than typical 1K spray paints. Caution: proper ventilation and personal protective equipment are essential when spraying in enclosed spaces.
TotalBoat TotalTread Non-Skid Deck Paint
TotalTread Non-Skid Deck Paint is a polyurethane coating designed for safety and durability on decks, docks, and steps. It provides a textured, low-glare surface that offers good traction while remaining easier to clean than silica-enhanced coatings. Best for: decks, cabin soles, and other high-traffic marine areas where slip resistance is essential. Limitation: texture may require more maintenance to preserve traction over time.
Buying Guide
- What is the difference between epoxy barrier coatings and topside polyurethane paints? Epoxy barrier coats (like TotalProtect) deliver superior adhesion and blister resistance for underwater or damaged gelcoat areas, forming a tough base. Topside polyurethanes (Wet Edge, Samura i, TotalTread) provide gloss, color, and UV resistance for above-water surfaces and decks.
- Do I need a 2-part system or can I use a 1-part paint? 2-part systems (like epoxy primers or Samurai 2K) generally offer stronger durability and chemical resistance but require careful mixing and ventilation. 1-part paints are simpler to apply but may need more frequent maintenance in harsh conditions.
- How important is surface prep? Preparation strongly affects adhesion and longevity. For epoxy primers, ensure the surface is clean, dry, and compatible with the coating to avoid delamination. For topside paints, remove old coatings or sand lightly to create a good bonding surface.
- What surfaces are supported? Most TotalBoat coatings work on fiberglass, wood, metal, and gelcoat when used as directed. Always verify compatibility for underwater vs. above-waterline use to avoid coating failure.
- How to choose a color? White finishes typically show fewer scratches and are easier to reflect sunlight, while blues offer a classic aesthetic. For decks, choose non-slip colors that align with safety and maintenance preferences.
FAQ
- Can I mix 2-part epoxy products with 1-part polyurethane paints? Generally not recommended without manufacturer guidance, as curing agents and film formation differ. Use systems as designed for best results.
- Is a primer necessary before topcoat? A primer, such as a marine-approved primer, improves adhesion and fills minor imperfections. Some topside paints claim one-coat coverage, but primers often provide stronger undercoats.
- What surfaces require barrier coats? Barrier coats are preferred on boats with blister-prone gelcoat, damaged paint layers, or exposed underwater metals to prevent water intrusion and corrosion.
- How long does each coating last under typical conditions? Longevity depends on exposure, maintenance, and surface preparation. Epoxy-based barriers tend to last longer under waterline conditions; topside polyurethane coatings offer excellent aesthetics and durability above waterline.
- What safety precautions are essential? Work in a well-ventilated area, use appropriate PPE such as respirators and gloves, and follow all label instructions for curing times and disposal.
- Can these coatings be spray-applied? Several options (Samurai 2K and some Wet Edge products) support spraying. Use appropriate spray equipment and settings recommended by the manufacturer for even coverage and safety.
