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

TotalBoat TotalFair is a lightweight, two-part marine epoxy fairing compound for filling, shaping, and repairing hulls, decks, keels and more.

If you need to repair dings, dents or gouges without a trip to the boatyard, this 2-pint kit gives you a high-strength, waterproof epoxy putty that sands smooth and bonds to fiberglass, wood, aluminum, steel and cast iron. The two components mix 1:1 and change to a green color when fully combined. TotalFair’s creamy, non-sagging texture holds on vertical and overhead surfaces, cures quickly at normal temperatures, and produces a pinhole-free surface ready for primer and paint.

How do I mix and apply TotalFair for best results?

Mix equal parts of the blue and yellow components until the color is uniformly green, about 3–5 minutes. Work on clean, dry surfaces and build depth in stages for narrow, deep repairs; follow a width-to-depth ratio to prevent cracking and ensure proper cure.

• Mix ratio: 1:1 by volume; mix until uniformly green.
• Consistency: thick, creamy—easy to spread and feather to edges.
• Application: apply with a spreader or putty knife; hold shape on vertical areas.
• Deep repairs: apply in layers if depth exceeds a 6:1 width-to-depth ratio.

Where can TotalFair be used on a boat and what substrates will it bond to?

TotalFair is formulated for marine repairs above and below the waterline and adheres well to common boatbuilding materials. Use it on outer hulls, topsides, keels, decks and areas that experience flex, keeping in mind proper surface preparation for durable adhesion.

• Suitable substrates: fiberglass, wood, aluminum, steel and cast iron.
• Locations: hulls, topsides, keels, decks, transoms and stringers.
• Waterproof once cured—appropriate for below-waterline use.
• Flex-tolerant formula reduces cracking on moving panels.

How fast does it cure and how do I finish it for painting or gelcoat?

At around 80°F, TotalFair reaches a sandable state in approximately 3–4 hours and produces a smooth, pinhole-free surface. Do not apply gelcoat directly over cured TotalFair; use an epoxy primer or barrier coat between the fairing compound and any gelcoat to ensure proper topcoat cure.

• Typical sandable time: ~3–4 hours at 80°F; cooler temps slow cure.
• Finishing: sands easily to a fine feathered edge for primer application.
• Gelcoat note: always apply TotalBoat 2-Part Epoxy Primer or TotalProtect before gelcoat.
• Safety: wear gloves when mixing and a respirator when sanding cured material.

How does TotalFair compare to other marine fairing compounds?

TotalFair combines lightweight fill with strong, waterproof bonding and better flex tolerance than many polyester or vinylester fillers. It offers an improved working feel—easier to scoop, mix and feather—while outperforming some traditional two-part epoxy putties in durability and water resistance.

• Stronger and more waterproof than most polyester or vinylester fillers.
• Foolproof 1:1 mix simplifies shop work and field repairs.
• Improved formula sands and feathers more cleanly than older mixes.
• Comparable alternatives: Interlux Watertite, Awlgrip Awlfair, System Three Quikfair—but with distinct TotalBoat formulation benefits.

Who is this for: TotalBoat TotalFair 2-pint kit is made for boat owners, DIY repairers, marine professionals and vehicle hobbyists who need a reliable, lightweight epoxy fairing compound for permanent, waterproof repairs. It’s ideal if you want an easy-to-mix, non-sagging filler that sands smoothly and bonds to a wide range of substrates—perfect for on-the-water fixes or workshop restoration projects. Store the kit at moderate temperatures (60–90°F) for best shelf life; note that cured TotalFair requires appropriate PPE during sanding.
