FCS Concrete Repairs gives great importance to the role of its Coating Inspector.
Erik Quintero is a NACE Certified Coating Inspector and has an important role in FCS Concrete Repairs as both our Senior Project Coordinator and Coating Inspector.
As a NACE Certified Coating Inspector his role in FCS Concrete Repairs includes that of a Quality Control Technician responsible to observe, test, verify and report on the compliance of protective coatings application with the manufacturer’s and the project specification, if present, during the application of the coating as well as after the work is completed.
The Coating Inspector’s work begins prior to commencement of the job. He should have the following information:
- the needs of the owner,
- the skill level of the applicator,
- the contract documents,
- the coating systems to be applied.
- All Specifications related to the work
- All applicable codes and standards
- The Manufacturers Product Data Sheets (PDS)
- The Manufacturer’s Material Safety Data Sheets (MSDS)
- Any drawings of area where work is being performed
There are a number of hold points to be observed:
Prior to Start of Work: Visual observation of the subject surface.
After Surface Preparation: Surface contamination and visual cleanliness.
Immediately Prior to Application of the Coating: Climatic conditions, materials inspection, observe mixing of the coating.
Following the Application of Each Coat: Dry film thickness, holiday testing, recoat time, coating cure.
Following the cure of the coating: Final inspection of dry film thickness, holiday testing.
Non-Conformance Reports should be prepared for serious issues.
Typical Inspection Equipment used by Coating Inspectors:
- Electronic Relative Humidity Temperature Meter
- Surface Temperature gauge – thermocouple type or Infrared Type.
- Dry Film Thickness Gauge:
- Type 1 Banana Gauge – Positest FM or equivalent with calibration plates or foils.
- Type 2 Electronic Gauge –Positector 6000 or equivalent with calibration foils
- Inspection Mirror or Boroscope
- Magnifying Glass or digital microscope
- Salt Testing Equipment (Conductivity or Chlorides)
- Black light for Oil Contamination
- Blotter Paper or clean white rag for testing air supply
- Surface Profile
- Test-Ex Tape & Spring Micrometer or Positectot RTR Probe (Replica Tape Reader)
- Surface Profile Gauge – Positector SPG
- NEW Positector RTRP Surface profile – Peak Density probe
- Holiday Tester if appropriate for the project
- VIS Standards appropriate for the project
- Paint Thermometer
- Optional – Blast Needle Gauge and Nozzle Orifice gauge
- Optional – Camera if Appropriate for the project.
