Using the incorrect grade may result in under-cure or over-cure, compromising the structural integrity and waterproofing of the GRP laminate. For example, using a Summer Grade catalyst in winter conditions may prevent full curing, while using Winter Grade in hot weather can lead to premature hardening during application.

Yes, as with most MEKP (Methyl Ethyl Ketone Peroxide) based catalysts, it is classified as hazardous. Always: - Wear appropriate PPE (gloves, goggles, protective clothing) - Ensure good ventilation - Avoid skin contact and inhalation - Store securely, away from heat and direct sunlight Refer to the product's Safety Data Sheet (SDS) for full handling and disposal instructions.

Store the catalyst: - In a cool, dry place (ideally below 25°C) - Away from direct sunlight or heat sources - In its original, tightly sealed container - Out of reach of children and pets Do not store with accelerators, metal powders, or flammable materials.

Cure time varies depending on temperature and catalyst percentage but typically ranges from 20 to 45 minutes. Always allow sufficient time for curing before applying subsequent layers or exposing the surface to weather.
