Practical method #
Record the product, batch, purchase details, installed location and timeline. Take overall and close-up photographs, including the supporting detail where safely accessible. Describe the observed behaviour without assuming its cause. Preserve relevant instructions, invoices and cleaning records. For an illustrative disputed stain or movement issue, provide the treatments used and conditions when it appeared. Follow the supplier's claims procedure and protect any unsafe area. Do not undertake destructive investigation before agreeing how evidence will be retained.
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.
