Product Instructions, Service Promises and Warranty Documents: Keep Their Roles Clear

A coating customer may receive application instructions, a service proposal and a warranty document. These documents should agree on product identity and scope, but they answer different questions.

Define each document’s role

Document	Main purpose
Product instructions	Explain approved application, conditioning and care
Service commitment	Describe work and support the provider will deliver
Warranty document	State the applicable promise, conditions and process

Check for contradictions

Review product names, covered surfaces, care requirements, dates and contact routes. A sales statement should not promise a function excluded by the technical instructions. Likewise, a service brochure should not casually expand a written warranty.

Use version control

Record which documents were supplied with the job or product. If instructions change later, retain the historical version and establish how affected users will receive relevant updates. Avoid replacing old records with a new file that makes the original handover impossible to reconstruct.

Keep legal interpretation with the responsible reviewer

Have warranty and binding service wording reviewed for the intended market and arrangement. Do not use this document map to infer that statutory rights disappear or that one document overrides applicable law. At handover, give the customer a clear route for routine care questions, service requests and warranty enquiries. Consistent documents make those routes easier to use without blending technical guidance into an unsupported commercial promise.
