FIBREGLASS POOL CATALYST 1KG

Description 

The Fibreglass Pool Catalyst 1kg is a must-have consumable for any pool contractor or homeowner dealing with fibreglass pool linings and repairs. This MEKP hardener is used to cure polyester resin and gelcoat, ensuring a proper chemical reaction that hardens the fibreglass layer. Without catalyst, resin will never set, leading to weak, tacky, or incomplete finishes.

One of the biggest challenges pool owners face is incorrect mixing ratios. Using too little catalyst means the resin stays sticky and weak; too much can cause overheating, cracks, or premature yellowing. That’s why the recommended mix is 1–2% by weight. For example, when working with 1kg of resin, you’ll need 10–20ml of catalyst depending on the weather conditions. Warmer weather accelerates curing, while cooler temperatures slow it down.

Another common frustration is delayed curing during winter. Pool professionals in South Africa often increase catalyst dosage slightly (never above 3%) to keep curing times manageable in colder climates.

Because this product is corrosive, safety is critical. Always use gloves, eye protection, and work in a ventilated area. Store it in a cool, dry place away from direct sunlight or flames.

This 1kg pack is ideal for contractors working on multiple jobs or homeowners tackling a larger pool relining project. With nationwide delivery available, you can keep your fibreglass projects on schedule anywhere in South Africa.

Extra FAQs Based on SA Pain Points

Q: Why is my resin still sticky after curing?
A: This usually means not enough catalyst was added or temperatures were too low.
