## Summary

A mock-up should test the difficult project interfaces, not just display the board colour. Record what it approves and what remains subject to technical verification.

## Practical method

Include a representative joint, edge, fixing and transition, plus any detail likely to be repeated at scale. Invite the relevant designer, installer and owner to resolve appearance and maintenance access before bulk work. For an illustrative public terrace, test how a board is removed from the sample assembly. Record acceptance criteria and unresolved items in writing. A visually accepted sample does not override structural calculations or manufacturer instructions. Keep photographs and the approved detail available to the installation team.

## 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.

## Key points

Representative interfaces
Written acceptance scope
Unresolved technical items

## Comparison

Design check | Evidence to record
Representative interfaces | Show the requirement on the project drawing
Written acceptance scope | Obtain applicable product or design evidence
Unresolved technical items | Assign installation and maintenance responsibility

## Approving a WPC mock-up before bulk installation — What should be confirmed before ordering?

A mock-up should test the difficult project interfaces, not just display the board colour. Record what it approves and what remains subject to technical verification. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation.
