Protite 500g Medium Fibreglass Repair Kit – LSE Resin & Matting | Australia

More Coverage, Same Professional Results

When the job is too big for a starter kit but you still want the convenience of an all-in-one solution, the Protite 500g Medium Fibreglass Kit is the answer. Packing 500g of fibreglass resin and 0.50m² of chopped matting, this kit is engineered for more substantial repairs — whether you’re patching a larger section of a fibreglass hull, reinforcing a cracked panel, or filling deep imperfections in metal or timber surfaces.

Larger surface damage left untreated can quickly escalate — water gets in, materials weaken, and what started as a simple repair becomes a costly replacement. The Protite Medium Kit gives you the materials and tools to address the problem properly the first time, with a proven LSE resin formulation that cures to a tough, resilient finish capable of standing up to the elements.

Key Highlights

• Low Styrene Emission (LSE) Resin — The LSE formula significantly reduces styrene vapour output compared to conventional resins, making it a safer and more comfortable option when working in garages, sheds, workshops or partially enclosed outdoor areas.
• Water Resistant Once Cured — The hardened repair surface resists water penetration, making this kit well suited to marine environments, outdoor structures and wet-area applications across Australia’s varied climates.
• UV Resistant — Formulated to withstand prolonged exposure to sunlight without degrading, yellowing or losing structural integrity — an essential quality for Australian outdoor conditions.
• Sandable & Paintable Finish — After curing, the surface sands back smoothly and accepts paint readily, allowing you to blend the repair seamlessly into the surrounding area for a clean, finished look.
• Stainable — Unlike many fibreglass repair products, this kit’s cured surface can also be stained, offering additional finishing flexibility for timber and decorative applications.
• Outdoor Rated — Specifically suited for outdoor use, the Protite 500g kit handles exposure to moisture, temperature changes and UV without compromising the integrity of the repair.
• Generous Coverage — With 500g of resin and 0.50m² of chopped fibreglass matting, this kit provides double the material of the small kit, making it ideal for medium to large repair areas in a single application.
• Complete All-in-One Kit — Includes 500g fibreglass resin, 0.50m² chopped matting, 15ml catalyst hardener, a measuring cup, applicator brush, mixing stick and mixing bucket — every tool and material you need, right out of the box.

Perfect For

The Protite 500g Medium Fibreglass Kit suits DIY homeowners, boat owners, caravan enthusiasts and tradespeople who need to repair larger areas of damage across fibreglass, metal and timber surfaces. It’s an excellent choice for patching fibreglass boats, camper trailers, water tanks, garden structures, roofing sheets and automotive panels. The outdoor rating and UV resistance also make it a go-to option for exposed repairs that need to hold up year-round in Australian weather conditions. If you’ve outgrown the small kit or know your repair area is more substantial, this is the right tool for the job.
