Intent
The sample library is treated as working technical equipment, not merely a sales display. Each useful sample should record material system, substrate, preparation, mix or color reference, application sequence, tools, sealer when applicable, date, and observed variation.
Why samples matter
Screens flatten texture and alter color. Small chips can obscure scale and hand movement. Project samples should be large enough to read at the intended viewing distance and under relevant light.
An approved sample establishes a controlled direction—color family, aggregate expression, texture, sheen, and acceptable movement—while acknowledging the honest variation of hand-applied mineral work.
