Evaluate the substrate first
The proposal should explain the material’s condition, cleaning steps and drying requirements before a product is applied. A finish over unresolved damage can make later inspection harder. Request the product information and discuss whether the material should instead be replaced.
Make the decision traceable
Keep photographs taken before coating, preparation records and the reason for using the product. Confirm whether the coating affects future inspection or finishing work. Acceptance should be based on the agreed scope, not only the appearance of a newly painted surface.
Ask why retaining the material is appropriate
The provider should explain the condition of the substrate and the reason for coating rather than replacing it. Confirm that any required cleaning and drying happen first. A product warranty is not evidence that the original leak has been repaired or that inaccessible areas were assessed.
Keep the product and preparation record
Request the product name, relevant instructions and photographs of the prepared surface. Ask about compatibility with later finishes and any inspection limitations introduced by the coating. These details help the next contractor understand the assembly without guessing what is underneath the finish.
