TotalBoat TotalFair Epoxy Fairing Compound — 2 Pint Kit, Lightweight 1:1 Marine Epoxy, Sandable & Waterproof

Built for boaters who want professional-grade results without a trip to the yard, TotalBoat TotalFair mixes 1:1 and cures into a tough, waterproof putty that sands smooth and accepts primer and paint. Its creamy, non-sag formula holds on vertical and overhead repairs, tolerates flexing, and adheres to fiberglass, wood, aluminum, steel, and cast iron for permanent patching from hull to topside.

How quickly does TotalFair cure and when can I sand or paint it?

TotalFair reaches a sandable state rapidly so you can keep your project moving. At about 80°F it becomes workable for sanding in roughly 3–4 hours; cooler temperatures will slow cure time.

• Mix components for 3–5 minutes until color turns uniform green.
• Sandable at approximately 3–4 hours at 80°F; allow longer in cooler conditions.
• Compatible with epoxy or latex primers; do not apply gelcoat directly over cured TotalFair.

Which surfaces and repair types is this fairing compound meant for?

TotalFair bonds to a wide range of marine materials and is formulated for cosmetic fairing and structural filling of dents, gouges, seams and irregular surfaces. Use it above or below the waterline on boats, or for similar repairs on RVs, cars and motorcycles.

• Works on fiberglass, wood, aluminum, steel and cast iron.
• Good for hulls, keels, decks, topsides, and patching around hardware.
• Waterproof when cured—suitable for underwater patches when properly applied.

What is the mixing and application process for reliable results?

The compound comes as a two-part system with an easy 1:1 mix ratio; simply combine equal portions of the blue and yellow cartridges until a consistent green color appears. Its thick, creamy consistency spreads and feathers smoothly and resists sagging on vertical areas.

• Mix equal parts by volume; stir 3–5 minutes until uniform green.
• For deep repairs follow a 6:1 width-to-depth rule or build in layers for deeper sections.
• Wear gloves for mixing and a respirator when sanding cured material.

How do I finish TotalFair before painting or gelcoat?

Sanded TotalFair provides a pinhole-free surface that accepts primer and paint. For gelcoat finishes, do not apply gelcoat directly; first prime with TotalBoat 2-Part Epoxy Primer or TotalProtect to ensure proper adhesion and cure of the gelcoat layer.

• Sands to a smooth finish; improved formula reduces pinholes.
• Compatible with epoxy and latex primers and most marine paints.
• Apply epoxy primer or TotalProtect before gelcoat to avoid curing issues.

Who is this for: TotalBoat TotalFair is designed for hands-on boat owners, marine technicians, and DIYers who need a fast-curing, waterproof fairing compound that sands easily and resists sagging. It’s ideal for people repairing moderate dents and gouges, fairing hulls and decks, or prepping surfaces for primer and paint. If you want an American-made, two-part epoxy filler that handles flexing and multiple substrates without specialty equipment, TotalFair is built for that role.
