## Description

From the manufacturer What's in the box 105 Epoxy Resin (250g) 205 Hardener (50g) Milled Glass Fibre Blend Microsphere Blend 2 x Syringes Biaxial Glass Tape, Plain Weave Glass Tape & Peel Ply Mixing Cups, Mixing Stick, Glue Brushes & Gloves Everything You Need in One Kit No hunting for extras - the 105-K arrives ready to work. Inside you'll find 250g of 105 Resin, 50g of 205 Fast Hardener, two specialist fillers, biaxial and plain weave glass tapes, peel ply, mixing cups, brushes, syringes, gloves, and illustrated step-by-step instructions for common fibreglass repairs. Everything comes in a sturdy, resealable package that stows neatly aboard your boat, so you're always prepared when damage strikes. WEST SYSTEM 105-K Glass Fibre Boat Repair Kit The WEST SYSTEM 105-K Fibreglass Repair Kit pairs 105 Resin and 205 Fast Hardener at a precise 5:1 ratio, delivering a high-strength, waterproof bond built for fibreglass, composites, and marine laminates. From gelcoat blisters and cracked hulls to delaminated decks and loose hardware, this kit handles the repairs that matter most. Cures to a solid state in just 5–7 hours. Purpose-Built for Fibreglass & Marine Repairs Engineered with marine-grade epoxy, fibreglass fabric, and specialist fillers, the 105-K tackles everything from small scrapes and gelcoat blisters to keel damage, delaminated panels, and holes up to 1″ in solid laminates. The included 402 Milled Glass and 409 Microsphere fillers let you match the repair to the job — structural strength or a smooth, sandable finish. Fully waterproof and salt-resistant, it's trusted by boat owners for lasting repairs in the harshest conditions. The foundation of the WEST SYSTEM epoxy range. 105 Resin is a clear, low-viscosity liquid epoxy designed to bond with wood fibre, fibreglass, reinforcing fabrics, composite materials, and a variety of metals. Formulated to work with all four WEST SYSTEM hardeners, it cures over a wide temperature range to form a high-strength solid with excellent moisture resistance. Whether you're coating, bonding, or laminating — 105 is where every project starts. 205 Fast Hardener (50g) The activator that brings 105 Resin to life. 205 Fast Hardener is designed for general coating and bonding applications, producing a rapid cure that develops physical properties quickly at room temperature. Mixed at a 5:1 ratio with 105 Resin, it forms a high-strength, moisture-resistant solid with excellent barrier coating properties. With a working time of 60–70 minutes and a solid-state cure in just 5–7 hours, it's ideal when you need fast, reliable results. 402 Milled Glass Fibre Blend When you need a repair that carries load, 402 is the filler to reach for. Blended into mixed epoxy, it creates a thick, high-strength paste perfect for bonding hardware, filling voids in laminates, and building up structural repairs where strength matters more than surface finish. 409 Microsphere Blend For repairs that need to look as good as they perform, 409 Microsphere Blend mixes into epoxy to create a lightweight, easily sandable fairing compound. Use it to smooth surfaces, fair hull imperfections, and create a clean profile ready for gelcoat or paint. 450g/m² Biaxial Glass Tape This 1m x 125mm strip of heavy-duty biaxial glass fabric provides reinforcement in two directions, making it ideal for structural repairs on hulls, keels, and high-stress areas. Wets out cleanly with 105/205 epoxy for a strong, lasting laminate. 175g/m² Plain Weave Glass Tape A 1m x 75mm strip of fine plain weave glass tape, perfect for surface repairs, gelcoat blister patches, and adding a reinforcing layer over smaller cracks and scrapes. Its lighter weight makes it easy to handle and conforms well to curved surfaces. Peel Ply Applied over wet laminate, this 1m x 100mm strip of peel ply compresses the repair, absorbs excess resin, and peels away to leave a textured, contamination-free surface that's ready for secondary bonding or coating - no sanding required for adhesion. Application Tools Every tool you need is included: 3 mixing cups for accurate batching, a reusable mixing stick, 2 glue brushes for applying resin and wetting out fabric, 2 syringes for injecting epoxy into tight cracks and delaminations, and 2 pairs of nitrile gloves to keep your hands clean. No extras to buy - just open and start your repair.
