MetroFlex Dark Grey 20kg

Our larger pack size, suited to full domestic flat roofs and bigger commercial roofing projects where more material is needed in one go. This 20kg container delivers the same low-viscosity, low-styrene, fire-retardant flexible resin, formulated to laminate with 300g chopped strand mat and cure to a flexible, high-elongation finish that's built to move with the structure beneath it rather than crack under stress. BRoof (t4) fire-rated, and compatible with Metroflex Primer for application to existing roof coverings and difficult substrates. As with the 5kg size, mix thoroughly before use, apply at a minimum working temperature of 18°C, and dose with Metroflex Powdered Catalyst - remembering to verify fire performance on a prototype for your specific roof build-up before full-scale application.
