FIBREGLASS POOL CATALYST 1KG

Product Description

The Fibreglass Pool Catalyst 1kg is a professional-grade MEKP (Methyl Ethyl Ketone Peroxide) hardener formulated for use with polyester resins, gelcoats, and fibreglass repair systems. Essential for ensuring correct curing, this catalyst initiates a fast and complete hardening process, delivering reliable and durable results for pools, boats, and composite projects.

Trusted by contractors and DIY enthusiasts alike, the catalyst is ideal for use in fibreglass pool linings, repairs to cracks or chips, marine builds, and general composite fabrication. By maintaining a consistent cure under normal South African climate conditions, it guarantees professional-quality finishes.

For best results, always measure the correct mixing ratio (1–2% by weight) relative to the resin or gelcoat. This ensures proper curing speed without overheating or under-curing.

⚠️ Important Safety Notice: Fibreglass catalysts are corrosive and should be handled with gloves, eye protection, and in a well-ventilated area. Store in a cool, dry space away from open flames.

FAQs (South Africa Search Intent)

Q: What is the correct mixing ratio for fibreglass catalyst?
A: Use 1–2% catalyst by weight of resin or gelcoat. For example, 10–20ml catalyst per 1kg resin, depending on working conditions and temperature.

Q: Can I use this catalyst for swimming pool lining?
A: Yes. This MEKP catalyst is specifically designed for polyester resin systems used in fibreglass pool lining and repairs.

Q: How long does the resin take to cure after adding catalyst?
A: At 25°C, resin typically begins to gel in 15–25 minutes and fully cures within 24 hours. Cooler weather slows the process, while warmer conditions speed it up.

Q: Is this catalyst compatible with gelcoat?
A: Yes. It works with both polyester resins and gelcoats, making it suitable for pool linings, top coats, and general composite applications.

Q: Can I store the catalyst once opened?
A: Yes, but it must be kept tightly sealed in a cool, dry, and ventilated place, away from direct sunlight and ignition sources.

Q: Is this product safe for DIY pool repairs?
A: Yes, but it must be used carefully with protective gear. Beginners are advised to consult instructions or professional guidance before attempting major pool relinings.

Q: Why is catalyst necessary for fibreglass work?
A: Resin cannot cure on its own. Catalyst triggers the chemical reaction that hardens resin into a solid, durable layer.

Q: Can I use too much catalyst?
A: Excess catalyst can cause overheating, brittleness, or discolouration. Always stick to the recommended 1–2% dosage.

Q: What if I don’t use enough catalyst?
A: Resin will cure too slowly or remain tacky, leading to weak bonding and potential failures in the fibreglass structure.

Q: Is nationwide delivery available?
A: Yes. Orders can be shipped across South Africa via courier (delivery within 2–7 working days depending on your area).
