From November 1st all fibreglass roof kits will include winter catalyst - We will issue winter catalyst by default unless requested otherwise

Catalysts are mixed into resins, gelcoats, topcoats and bonding paste to initiate the curing reaction to turn the liquid or paste into a solid, durable material.

Addition is 2% at room temperature. More or less may be required depending on the working temperature (slightly less for warmer conditions and more for colder climates). Generally, never less than 1% and never more than 4%. This material is highly flammable and corrosive, great care should be taken when handling and storing this product.

For catalyst addition charts please see our blog post 'How much hardener'
