MetroFlex Dark Grey 5kg

A practical pack size for smaller flat roofs, repairs, and trialling the Metroflex system before committing to a full roof's worth of material. This 5kg tin contains the same pre-accelerated, low-viscosity, fire-retardant flexible polyester resin used across the range, designed to be laminated with 300g chopped strand mat and to cure with high elongation and flexibility, helping the finished roof accommodate movement without cracking. It's BRoof (t4) fire-rated and, when paired with Metroflex Primer, can be applied over many existing roof coverings and difficult substrates. Mix thoroughly before use, apply at a minimum of 18°C, and catalyse with Metroflex Powdered Catalyst.
