A floor inspection report arrives with a set of pull-off readings and a note that the coating passed. Before you file it with the closeout documents, check what was tested, where the readings came from and which acceptance criteria were used.
For industrial epoxy flooring, the number is only part of the record. A useful report lets your facilities team connect each result to a location and understand the inspector's conclusion. You should be able to follow that connection without reconstructing the job from emails months later.
Establish which question the test answers
Pull-off testing applies a tensile load perpendicular to the coated surface. ASTM D7234 addresses coatings on concrete. The result depends on the test assembly, and separation can occur within the concrete, within a coating layer, between layers or at the test adhesive. The method also identifies the test as destructive, so repairs may be needed afterward.
Ask whether the report concerns a trial area, an investigation of an existing floor or acceptance testing of completed work. These serve different project decisions. A result from a trial panel should be labeled so it cannot be mistaken for a reading from the finished installation.
Find the test locations before comparing readings
Request a marked floor plan or a location list that your maintenance team can use. Each reading should have an identifier matching its photographs and notes. For a phased project, include the room or zone and installation phase.
Then compare the locations with the agreed inspection scope. Were the specified areas tested? Are any locations missing? If a test was relocated because equipment blocked access, ask for that change to be recorded.
For example, a report labeled only "production floor" leaves an avoidable question: which of several production rooms does it describe? Room numbers, grid references or marked photographs make the record usable. Agree on that naming system before the inspection.
Read the failure description alongside the number
The word "failure" describes where the test assembly separated under load. It does not, by itself, mean the installed floor has failed its acceptance requirements.
Elcometer's guidance on assessing pull-off results distinguishes separation within a material, known as cohesive failure, from separation at an interface, known as adhesive failure. More than one mode can appear in a single test. It also explains why the condition of the test glue matters when interpreting a result.
Ask for photographs of both the exposed surface and the detached test piece, with the inspector's description. If the report records glue failure or a mixed result, request an explanation under the specified test method before treating the reading as evidence of acceptance or rejection.
Check the test setup and timing
ASTM D7234 notes that instruments and loading fixtures can produce different results. It also calls for sufficient coating cure before testing, using the manufacturer's guidance and accounting for site conditions. Keep the instrument identification, fixture information and test date with the results.
If two reports appear to conflict, ask the inspector to explain whether their methods, equipment, coating age and test locations are comparable. Avoid selecting whichever number supports the preferred outcome.
For an industrial epoxy floor coating project, put the coating system and relevant application dates in the same closeout record. That makes it easier to review the test timing without searching through a separate contractor's daily log.
Ask where the acceptance criteria came from
A report should identify the project requirement used to judge the results. Request the relevant specification section, approved inspection plan or written manufacturer requirement. If the criteria are missing or inconsistent, resolve that with the responsible project team before signing off.
Ask how individual results and any retesting were evaluated under that requirement. A single "pass" statement is difficult to audit when the underlying criterion is absent. Keep revised reports and the reason for each revision together.
This is also a useful distinction when comparing proposals for industrial floor coatings: confirm what inspection and reporting are included before comparing prices. Our flooring services page outlines the systems we work with; inspection requirements should be defined for the actual project.
Close the report with repairs and outstanding items
Identify who will repair test locations and document their completion. If the inspector recommends further investigation, assign that item a responsible person and a response date rather than leaving it buried in the report.
DeFelsko's concrete coating quality-control guidance discusses adhesion alongside surface preparation, environmental conditions and coating thickness. Keep those records together where they form part of your project requirements. An adhesion report should sit within the inspection package, with any unresolved issues visible at handover.
Frequently asked questions
Does every industrial epoxy flooring project need pull-off testing?
Check the project specification and agreed inspection plan. Ask the responsible specifier or manufacturer to define whether testing is needed, its scope and the acceptance criteria before installation.
Does separation within the concrete mean the coating failed?
It identifies where separation occurred during that test. The inspector must evaluate the measured strength and failure mode against the applicable project requirements before reaching a conclusion.
What should I request if the report only says "passed"?
Ask for the individual readings, locations, failure descriptions and the acceptance criteria used. Include photographs and any retesting or repair records in the closeout package.
Plan the inspection before the floor goes in
If you are planning epoxy floor coatings for an operating facility, send us your floor plans, service conditions and inspection requirements. We can discuss the flooring scope and the documentation needed for your project. Contact us about your industrial flooring project.
