Practical method #
Label the sample with profile, colour, batch if available and date. View it outside in the light expected on the project, beside the proposed paving and façade. Examine the edge, groove and any protective cap, then ask how cut ends will be finished. A useful illustrative mock-up includes two boards, their joint and the proposed fixing rather than one loose piece. Record colour acceptance separately from technical approval. Request applicable test reports and installation instructions for performance decisions; photographs on a screen are not a physical colour standard.
Planning and verification #
Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.
Handover and maintenance #
Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.
