Reviewing Composite Colour Samples in Outdoor Light
Composite colour samples should be reviewed in the outdoor setting where they will be used. The review can establish initial appearance, while any weathering expectations should come from the selected product's supporting information.

Selection considerations
Compare samples in both direct and shaded outdoor light with adjacent stone, planting and metal finishes. Record the product code and finish reference. A small sample viewed indoors may not show how a large deck reads under changing daylight.
Ask the supplier for the relevant finish and weathering information. Do not infer a universal fade rate or maintenance-free life from the term composite. If a previously exposed sample is provided, identify its history and keep it separate from the current delivery control sample.
Agree the acceptable initial appearance and retain an identified sample. Map delivered batches to zones where consistency matters. Future replacement decisions should compare the new sample with the installed surface as well as the original reference, with any difference agreed by the owner.
Before you specify or order
- Review samples outdoors
- Record exact finish references
- Obtain product-specific weathering information
- Retain an initial control sample

Common question
Does an outdoor sample predict every long-term colour change?
No. It supports the appearance review; assess weathering expectations using relevant product information and exposure conditions.
