Preparation	Clean surface thoroughly; remove grease, oils, dust, and loose material. Sand rough or smooth surfaces to promote adhesion. Polystyrene foam should be coated with water-based product before polyester application. Mix catalyst into resin (1–4% by volume) and disperse quickly in shallow trays to avoid heat buildup.
Application	Brush a thin coat of mixed resin onto the repair area. Press pre-wetted fibreglass matt or cloth into resin; apply additional resin until fully saturated. For filler coats, mix MICROTALC with resin and catalyst to achieve trowellable consistency. After curing, sand and paint as needed.
Precautions	Use only Norglass Polyester Catalyst; do not use accelerator. Flammable – keep away from naked flames. Wear protective glasses and gloves; avoid eye contact. Wash thoroughly after handling; keep out of reach of children. Do not store resin-soaked rags in confined spaces.
First Aid	Poisoning: call doctor or Poisons Information Centre (AUS: 13 11 26 / NZ: 0800 764 766). If swallowed: DO NOT induce vomiting; give water or milk. Eye contact: flush with water for at least 15 minutes and consult doctor. Skin contact: remove contaminated clothing, wash thoroughly. Breathing difficulty: move to fresh air; apply artificial respiration if necessary.
Special Instructions	Follow gel time recommendations; do not mix more resin than can be applied within 10 minutes at 20ºC.
