34 JANUARY 2018 COATINGSPROMAG.COM or at the end of each spray pass. is powder presented as fine clouds, mostly visible when crossing natural light. e specification requested a tolerance ≥ rating 2, which requests removal of visible dust as described in the standard but doesn't deal with non-vis- ible dust. is contamination was widespread and presented a significant risk to the coating adhesion. e head contractor along with the applicator said, "e specification says we only need to supply four compliant tape tests, and we have achieved that." is situation is difficult because the client hadn't provided me with authority, and the specification didn't effectively deal with dust contamination. I first asked the client to provide a site instruction to include the reclean- ing of any areas of surface dust found to not comply with the specification. Second, I asked the coatings manufac- turer if it would endorse application over a powdery dust layer. e coating manufacturer's response hit my inbox before the client could get back to me. Obviously, the answer was a resound- ing "no." W hen this was confirmed via email, I forwarded it to all parties and recommended that the coating application be halted until cleanliness was achieved. During this time, the applicator had applied coatings to 25 percent of the tank's floor area. I did not have the authority to prevent this work, however, through my effort, the team decided to reclean the remaining floor area. Strictly speaking, a non-confor- mance was not applicable, however, all information was captured in my report for future reference, and the client responded by thanking me a few weeks later. Excellence and Improvement A coatings inspector does not perform surface preparation, provide materials, nor apply coatings. Nor does he or she provide a warranty or guarantee of the coating performance. Our role as coatings inspectors is to observe, inspect, test, and report. We are, however, requested to observe the project documentation and report compliance and non-compliance in accordance with the specification, standards referenced, manufactur- ers' data sheets, and written site instructions. On projects where workmanship is poor, our inspection reports should include twice as much data to describe Inspector's Corner FLOOR MOISTURE ISSUES?
