RapidRoof Waterproof Catalyst (300g)

£30.00 ex VAT (£36.00 inc VAT)

The catalyst for RapidRoof's PMMA resin, dosed to control cure speed on site — more in cold weather keeps the 30-minute cure on track, less in heat buys extra working time. Best measured against RapidRoof's own dosing chart for a reliable, even cure.
