Polyester Repair Kit Talamex - Gelcoat & Fibreglass (250 g) | 4Boats

Compact Talamex polyester repair kit for quick small repairs to gelcoat, fibreglass and GRP surfaces on boats and marine equipment.

• Contents: 250 g polyester resin, 20 ml MEKP (methyl ethyl ketone peroxide) catalyst, 0.5 m² (5.4 ft²) glass fibre cloth
• Mix ratio: add 1–2% MEKP by weight (approx. 2.5–5 g for 250 g resin). Start with ~1% for standard cure; adjust within range for faster or slower curing as needed.
• Working time (pot life): approx. 6–12 minutes at 20 °C with 1% MEKP (shortens with higher catalyst or higher temperature)
• Sandable: typically 1–3 hours (depending on layer thickness and temperature); full cure ~24 hours at normal ambient conditions
• Recommended ambient temperature for use: 10–30 °C (best results 15–25 °C); avoid use below 10 °C or in very humid conditions
• Sanding guide: coarse shaping P80–P120, blend and feather with P120–P180, finish with P180–P320 before priming/painting
• Paintability & compatibility: cures to a polyester-compatible, sandable filler—suitable for polyester gelcoat and most marine topcoats (polyurethane/alkyd). Not recommended for direct use over epoxy systems—test on an inconspicuous area before full application
• Coverage: sufficient for patching areas up to 0.5 m² (5.4 ft²) depending on laminate thickness and build-up
• Fast-curing catalyst enables quick work cycles in normal ambient conditions; 20 ml MEKP provides ample catalyst for multiple small repairs
• Easy-to-mix single-kit solution for workshop or on-deck repairs; ideal for restoring smooth surfaces prior to topcoat or touch-up paint
• Safety: store in a cool, dry place; use chemical-resistant gloves, eye protection and ensure good ventilation. Avoid skin contact with MEKP and resin; follow local disposal regulations

Compatible with most polyester gelcoat systems and GRP/laminate repairs; not intended for epoxy laminates—always test on an inconspicuous area before full application.
