TotalBoat TotalFair is a lightweight, 2-part marine epoxy fairing compound perfect for reshaping, filling, and fairing. TotalFair fairing putty is ideal for boat building and repairs above and below the waterline on fiberglass, gelcoat, wood, and properly prepared metals. TotalFair dries fast and sands smooth. Color-coded components make the 1:1 mix ratio easy.

Safety & PPE

Always use proper safety equipment, clothing, and PPE in accordance with the Safety Data Sheet for each component.

Exothermic Reaction Warning: The cure of TotalBoat TotalFair is an exothermic reaction and will generate heat. Though TotalFair is generally applied in thin, small applications, larger mixed masses can reach 200°F or higher during cure.

Surface Preparation

• All surfaces must be free of contaminants, including amine blush, dust, dirt, grease, moisture, water, oil, and wax.
• Important: Only use clean cotton rags for surface preparation. Synthetic rags can leave a film of contamination when used with some solvents.
• The minimum width-to-depth ratio for TotalFair is 6:1. Bevel or grind sides to meet this ratio; greater ratios are encouraged.

Fiberglass / Gelcoat

• Remove amine blush with fresh, warm water and mild soap; dry completely.
• Remove any waxes using a dewaxing product.
• Abrade with 80-grit or coarser sandpaper; remove residue; wipe with a clean cotton rag dampened with a listed prep solvent; dry completely before applying TotalFair.

Epoxy

• Remove any potential amine blush with warm, soapy water; dry completely.
• Wipe with a clean cotton rag dampened with a listed prep solvent.
• Abrade with 80-grit or coarser sandpaper; remove residue; wipe again with solvent; dry before applying TotalFair.

Wood

• Wipe with a listed prep solvent; for oily hardwoods or white oak, use acetone if possible.
• Allow solvent to evaporate; abrade with 80-grit or coarser sandpaper; remove residue; wipe clean with solvent; dry completely before applying.

Metals

Steel / Iron: Wipe with solvent; grind or sand with 80-grit or coarser sandpaper to bright metal; remove residue; wipe again. Applying TotalBoat Rust Primer is highly recommended, but not required. Ensure the surface is fully dry before applying TotalFair.

Stainless Steel: Wipe with solvent; abrade with 80-grit or coarser sandpaper; remove residue; wipe with solvent; dry completely.

Aluminum: Wipe with solvent and dry. Abrade with 80-grit sandpaper or grind immediately before bonding, or etch with TotalBoat Aluminum Boat Etch Wash as directed. Remove residue, solvent wipe, dry, and apply TotalFair within 1 hour of prep.

Lead Safety Alert: Use extreme care and proper PPE. Wipe with solvent; grind or sand with 80-grit sandpaper to shiny and rough; remove residue; wipe again; allow solvent to evaporate and apply TotalFair immediately. Lead oxidizes rapidly. If not applied within minutes, repeat prep.

Lead — Alternative Method: Grind to bare lead and immediately coat with TotalBoat TotalProtect; apply as many coats as directed. After 24–48 hours, wash with warm, soapy water; rinse and dry; sand with 80-grit sandpaper, avoiding sanding through; then apply TotalFair to the sanded TotalProtect surface.

Other Metals: Wipe with solvent; grind or sand with 80-grit or coarser sandpaper to shiny and rough; remove residue; wipe again; dry completely; apply TotalFair within 1 hour of prep.

Uses & Applications

• Epoxy-based fairing compound that creates a durable, resistant, dimensionally stable surface for multiple topcoats.
• Waterproof; usable above or below the waterline.
• Once cured, can be primed and painted. See topcoat instructions below.
• Do not apply gelcoat directly to TotalFair; follow gelcoat procedure below.
• Not UV stable; not a finish material.
• Not a substitute for structural repairs; not an adhesive — do not use for bonding.

Dispensing & Mixing

Application Conditions

Only dispense and apply when ambient, epoxy, and substrate temperatures are 50–90°F and RH ≤ 90% for the first 24 hours of cure. In cooler conditions, warm components to 70–80°F for easier dispensing and improved workability.

Mix Ratio

• By volume: 1A:1B (resin : hardener)
• By weight: 100A:71B (100 parts resin (yellow) : 71 parts hardener (blue))

Mixing Notes

• The blue component may appear drier or oxidized at the surface — this is normal.
• Use clean tools and surfaces; mix only within specified environmental conditions.
• Initial mixing may feel thick for 30–60 seconds, then becomes creamy and easy to spread.
• Only mix what you can apply in 15–20 minutes.
• Mix 3–5 minutes until fully uniform green; no yellow or blue streaks.
• Do not vigorously whip — avoid entrapping air, which can create pinholes.

Application

• Apply to properly prepared substrates immediately after mixing to maximize working time.
• Use spreaders, trowels, mixing sticks, or similar tools.
• Maximum thickness per application: 3/4"
• Minimum width:depth ratio: 6:1; wider is encouraged.
• For depths > 3/4", build in layers: apply the next layer when the previous layer is mostly tack-free. If the surface becomes sandable, sand with 80-grit or coarser sandpaper and clean before the next layer.
• Strongly recommended to sand within two days; otherwise sanding effort increases.
• After sanding with 80-grit or coarser sandpaper and cleaning, more TotalFair can be applied as needed.
• If pinholes appear during sanding, work more TotalFair into cavities with a spreader.

Curing

Cure rate depends on ambient temperature, substrate temperature, and applied mass. Thicker applications cure faster; thinner applications may require more time. Full cure: 5–7 days (warmer temperatures shorten cure time; cooler temperatures extend cure time).

Primers, Topcoats & Gelcoat Over TotalFair

• TotalFair is considered non-blushing, but always wash the cured surface with mild soap and warm water, rinse, and dry before sanding or coating.
• Sand TotalFair before applying primers or topcoats.
• Epoxy-based products may be applied as soon as 24 hours after TotalFair was applied and sanded.
• Non-epoxy-based primers or paints: wait a minimum of 48 hours after TotalFair was applied and sanded.
• Do not apply gelcoat directly to TotalFair — follow the steps below.

Applying Gelcoat to TotalFair

1. After TotalFair has cured enough to be sanded, wash with mild soap and warm water; rinse and dry completely.
2. Sand with 80-grit sandpaper; remove residue; wipe with an approved prep solvent.
3. Apply TotalBoat TotalProtect as directed.
4. Allow TotalProtect to cure 5–7 days.
5. Before sanding TotalProtect, wash with mild soap and warm water; rinse and dry completely.
6. Sand with 80-grit sandpaper; remove residue; wipe with approved prep solvent.
7. Apply gelcoat as directed.

Product Storage & Shelf Life

• Store 59–77°F, sealed tightly, in a dry place before and after use; avoid floors, windows, and doors that expose epoxy to cool conditions.
• For storage > 30 days, cover product surface in the container with poly sheeting or plastic wrap before closing lid to prevent air or contaminant contact.
• Shelf life: Minimum 2 years if stored properly.
