Installation
Ensure surfaces are free from dust, debris, frost, or condensation, and prime with Puraflex Primer until dry. Peel back the release paper to expose the adhesive, apply to the primed substrate using a hot air welder where possible, and brush to remove trapped air for a strong bond. Overlap laps and junctions by a minimum of 150 mm. Contact Next Day Steel at 020 8079 7719 for further installation details or technical advice.

Protection & Repair
Inspect installed areas for defects, holes, blisters, or contamination before covering, ensuring a clean surface. Assess the need for additional protection (e.g., Cordex Correx system) before reinforcement or concrete placement. Repair damage with patching as needed.
