Wood-Look WPC Samples: Approving Colour and Texture Under Project Lighting
Approve a wood-look WPC sample with the intended lighting, viewing direction and nearby finishes recorded. Identify the exact sample and keep a labelled reference after the review. A screen image is useful for a shortlist, but the physical approval record should state the colour, texture and arrangement that the project team actually assessed.
Why should the sample review record lighting conditions?
Record the room or review location, the available daylight and the artificial lighting used during the sample assessment. If the project has a lighting schedule, identify the relevant fittings or settings rather than describing the conditions only as bright or warm.
Put the sample beside the intended neighbouring finishes where practical. Flooring, paint, furniture and metal trims can affect the appearance the designer is trying to coordinate. Keep the comparison conditions consistent when reviewing several options together.
For a hypothetical lobby with daytime and evening scenes, review the shortlisted samples under both intended conditions. A selection made beside a window may look different in an interior corridor. The record should identify which setting was used for acceptance and whether another lighting condition still needs review.
How should grain direction and texture be compared?
Compare the grain direction and surface texture as well as the general colour. Mark the proposed top or installed direction on the back of the sample, and photograph that orientation alongside its label. Keep the visible face identifiable in the record.
Look at the sample from the viewing positions that matter to the project. A close view can reveal texture, while a more distant view helps judge the repeated pattern. Where light travels along the face, the review may reveal differences that a straight-on catalog image does not show.
Recording direction keeps the later layout tied to the approved appearance. If the design allows some pieces to be rotated, say where and how that decision will be reviewed. Do not assume that a piece with the right dimensions can be turned freely without changing the intended visual result.

When is a larger assembled sample useful?
Use a larger assembled sample when a small piece does not explain the repeated design, panel joint or transition to the next material. Choose the assembly to answer the unresolved question instead of increasing sample size without a purpose.
An assembled section can help the team review the relationship between the face pattern and the panel boundary. It can also show a proposed corner or edge treatment. Label the components and keep the actual panel references in the review record.
For example, a small wood-look swatch may show the preferred tone but reveal little about a broad wall of repeated grooves. A representative assembly under the proposed lighting can support that visual decision. Its acceptance still applies to the identified assembly and conditions; it does not establish every property of the eventual installation.
How should the retained approval sample be labelled?
Give the retained sample a stable reference and label its product family, finish code, review date and approval revision. Include any direction mark, accepted visual notes and the drawing or room schedule it supports. Keep an overview photograph of the label with the sample.
Store the reference according to the material's supplied handling guidance and identify who holds it. If several parties retain samples, record which physical reference governs the approval and how the others relate to it. Unlabelled duplicates can lead to different comparison standards later.
Keep rejected and superseded options distinct from the current reference. An older sample may still be useful as a record of an abandoned choice, but it should not be mistaken for the accepted finish. Link any replacement reference to the decision that changed it.

What should buyers document for later batch comparisons?
Record the approved sample reference, any supplier finish identifier and any supplied batch information in the order documents. When a later delivery or repeat order is compared, state the lighting and viewing conditions again so the comparison can be understood.
Separate the original appearance approval from the later material review. The retained sample explains the chosen visual reference; it does not prove that a later batch has already been assessed. Record actual observations and any difference requiring discussion against the agreed criteria.
The table below keeps those records connected. If the finish identifier, surface process or proposed material changes, ask whether another sample review is needed. A familiar marketing name is not enough to establish that the reviewed reference and a new offer describe the same material.
| Record | Include | Review basis |
|---|---|---|
| Identity | Sample ID and supplier finish reference | One current reference |
| Review conditions | Location, daylight and artificial lighting | Repeatable comparison |
| Direction | Top mark, grain orientation and viewing positions | Consistent visual intent |
| Assembly | Panel joints and adjacent finishes reviewed | Scope of approval |
| Retention | Holder, date and revision history | Reference available for later checks |
Use the interior WPC wall panel collection and the related selection guide to narrow the product family before preparing the approval record. Contact the team with the sample identifiers, intended room conditions and the questions that remain open. Keep the retained physical reference connected to the enquiry so that colour and texture are discussed against the same starting point.
