Identify what is visible
Wide and close views help separate a coating failure from loss of base material. Do not remove additional material to make a photograph more revealing.
Review the supporting information
Existing drawings, inspection findings and repair history can change the scope. Where structural significance is uncertain, the appropriate professional should define the repair requirements.
Specify the work rather than a generic patch
The proposal should identify preparation, removal limits, repair materials and finish boundaries based on the selected details.
Photos help start the review. Access, concealed conditions and required professional review can change the construction scope.
