TotalBoat Epoxy Fairing Compound 2 Quart Kit — lightweight 1:1 mix, sandable & waterproof

TotalBoat TotalFair is a lightweight, two-part marine epoxy fairing compound for filling, shaping, and repairing dents, gouges, and voids above or below the waterline.

If you want a professional-feeling fairing putty without hauling your boat to a yard, the TotalBoat TotalFair 2 quart kit is made to be mixed and applied by hand. This 1:1 epoxy system blends blue and yellow components into a green, creamy paste that spreads easily, holds on vertical and overhead surfaces, and cures to a hard, waterproof surface that sands smoothly. It bonds to fiberglass, aluminum, steel, wood and cast iron and is formulated to tolerate flex without cracking — making it suitable for hulls, decks, keels, topsides, and non-marine repairs like cars, RVs and motorcycles.

How do I mix and apply TotalFair so it cures correctly?

Mix equal parts of the blue and yellow components by volume until the material turns a uniform green, typically after 3–5 minutes of thorough mixing. Work in room temperatures between 60–90°F for best handling and curing performance.

• Mix ratio: 1:1 by volume; mix until color is uniform green
• Application: scoop, spread, and feather to a fine edge; holds on vertical/overhead surfaces
• Layering: follow a 6:1 width-to-depth guideline; build deeper fills in stages
• Temperature: store and use between 60–90°F for best results

How long until TotalFair can be sanded and painted?

At 80°F the compound becomes sandable in just a few hours, giving you a quick turnaround for prep and finishing. Cured TotalFair sands to a smooth, pinhole-free surface and takes primers and paints designed for epoxy bases.

• Sandable at ~3 hours at 80°F; full cure time varies with temperature and thickness
• Compatible with epoxy and latex primers; use TotalBoat epoxy primer or TotalProtect before gelcoat
• Wear gloves when mixing and a respirator when sanding cured material

Where can I use TotalFair — is it waterproof and structurally strong?

TotalFair cures to a waterproof, high-strength epoxy that resists cracking under flex better than polyester or vinylester fairing compounds. Use it above or below the waterline on multiple substrates for permanent repairs and fairing work.

• Suitable substrates: fiberglass, aluminum, steel, wood, cast iron
• Waterproof cure: designed for both above- and below-waterline repairs
• Higher flex tolerance than polyester/vinylester fillers for long-lasting repair

Are there any finishing or compatibility caveats I should know?

Do not apply gelcoat directly over cured TotalFair; gelcoat will not cure properly on untreated epoxy. For cosmetic gelcoat repairs, first seal TotalFair with a TotalBoat 2-Part Epoxy Primer or TotalProtect Barrier Coat to ensure proper adhesion and curing of subsequent gelcoat or paint layers.

• Do not apply gelcoat directly on cured TotalFair
• Use TotalBoat epoxy primer or TotalProtect before gelcoat
• Compare favorably to other marine epoxy fillers for strength and waterproof properties

Who is this for? TotalBoat TotalFair 2 quart kit is aimed at boat owners, DIY repairers, and professional yard technicians who need a dependable, easy-to-mix fairing compound that sands smooth and holds up in marine environments. It’s also a strong choice for RV, auto, and motorcycle hobbyists who want a lightweight, waterproof epoxy filler that bonds to multiple materials and tolerates flexing without premature failure.
