PROPOSED CHECKS — NO MEASURED RESULTS SUPPLIED
Date: __________________  Units: __________________
Room / product reference: __________________

1. Product-specific change vocabulary
Where: At the proposed worktop sample with the exact finish information, not a generic material photograph.
Record: Ask the supplier to distinguish anticipated staining, etching, scratches, heat effects, and coating wear; record the remedy and limitation for each applicable change.
Your observation: ______________________________________________
Interpretation: A word such as patina cannot establish that every mark is cosmetic or repairable, and the worksheet supplies no substitute product rating.
Alternative: Reject vague reassurance and compare another specified surface if the household cannot understand what change it is accepting.

2. Cooking-to-care match
Where: Across the sink, preparation, coffee, and serving locations during ordinary meal preparation.
Record: List frequent ingredients, wet tasks, warm objects, and how long spills normally remain before cleanup; match these habits to written care requirements.
Your observation: ______________________________________________
Interpretation: The routine identifies likely conflicts without proving a particular chemical or heat exposure will damage the chosen product.
Alternative: Use the expressive material in a smaller less-exposed zone and specify the main working area separately.

3. Agreed sample response
Where: With all regular kitchen users reviewing an appropriate sample under the intended task light.
Record: Use only a supplier-permitted demonstration or test; document the treatment, approved cleanup, visible change, and each user's acceptance.
Your observation: ______________________________________________
Interpretation: One permitted sample comparison cannot predict all future marks, but disagreement is useful evidence against an assumed shared tolerance.
Alternative: Choose a different finish or maintenance burden before ordering when users do not welcome the demonstrated appearance.

PRACTICAL TRIAL
1. Ask whether a local repair changes adjacent appearance or requires treating the whole area.
2. Write who performs periodic maintenance and how the owner recognizes its need.
3. Compare joints and independently replaceable sections before pursuing one uninterrupted span.

COMPARE THE SAME SCOPE
- Actual product and installed fabrication detail
- Preparation, treatments, and periodic maintenance scope
- Local repair versus larger renewal and access
Cost drivers: Recurring specialist treatments or cleaning; Complex cutouts and uninterrupted large spans; Replacing sections beside retained appliances
Choose another route when: A visibly changing worktop is unsuitable when its described care conflicts with routine cooking or regular users do not share tolerance for its expected changes.

EVIDENCE BOUNDARY
No surface has been tested here. A proposed permitted sample exercise cannot establish long-term resistance, warranty performance, or a technical repair method.

DECISION CONDITIONS
choose: Choose the surface after all regular users understand its likely changes, permitted care, and repair scope and accept them in relation to actual cooking habits.
alternative: Place the expressive material in a smaller dry or serving area while specifying intensive preparation and wet zones separately when care demands exceed the ordinary routine.
stop: Stop the order if the supplier cannot distinguish the relevant changes or if users disagree about the demonstrated appearance but are being reassured that every mark will age beautifully.

The Natural Stone Institute distinguishes stone composition, staining and acid-related etching; sealing does not make stone stain-proof. For a natural-stone candidate, ask which changes are expected instead of treating patina as one outcome.
Scope: Natural-stone care guidance does not establish the performance of engineered, timber, or laminate products or authorize a home chemical test.
