Kayak Maintenance & Repair Supplies

For fiberglass kayak repairs you'll typically need fiberglass cloth or mat, an epoxy resin and hardener, and a gelcoat repair kit to restore the surface finish. Products like West System or System Three epoxy paired with Fiberlay fiberglass cloth tape are a solid starting point for most hull repairs.

Yes — most minor cracks and scratches on fiberglass or composite kayaks can be repaired at home. A gelcoat repair kit handles surface scratches, while deeper structural damage calls for fiberglass cloth and epoxy resin. J-B Weld MarineWeld is also great for quick, strong spot repairs above or below the waterline.

303 Aerospace Protectant is a UV-blocking spray that protects your kayak's hull, cockpit, and rubber components from sun damage, fading, and cracking. Think of it as SPF 40 sunscreen for your boat — regular use keeps gelcoat and plastics looking new and extends the life of your gear.

Chopped strand mat (CSM) uses randomly oriented short fibers for stiffness and is easy to wet out, while woven roving uses heavy directional weaves for tensile strength and bulk. They're commonly used together in alternating layers to achieve the best glass-to-resin ratio and overall laminate strength.

Aquaseal + FD is excellent for sealing seams, patching small holes, and waterproofing flexible materials like dry suit gaskets, waders, and kayak spray skirts. It stays flexible when cured, making it ideal for gear that flexes on the water.

West System Epoxy Resin and System Three Cold Cure are both trusted choices for fiberglass kayak repairs. Cold Cure is especially useful on the West Coast where you may be working in cooler temperatures — it can be applied down to 2°C and cures overnight.

Clean and dry the damaged area, mix the gelcoat paste with hardener per the kit instructions, apply to the scratch or chip, cover with the Mylar film to cure, then wet-sand and buff to blend. Kits like the Gelcote Repair Kit with Colours include tints so you can match your hull colour.

J-B Weld MarineWeld is specifically formulated for marine environments and retains full strength underwater. It bonds aluminum, fiberglass, composites, and metal, sets in 4–6 hours, and fully cures in 15–24 hours — making it a reliable fix for hull repairs, fittings, and trailer hardware.

The Harbour Chandler carries a full range of kayak maintenance essentials including 303 Protectant, Aquaseal, fiberglass cloth and mat, gelcoat repair kits, epoxy systems, and more — all shipped across Canada with a focus on West Coast paddlers.

A boat bailer sponge is used to soak up water from the bilge, cockpit, or deck of a kayak or small boat. The Seachoice Super Absorbent Sponge is a compact, high-capacity option that handles saltwater cleanups and tight spaces with ease.
