What percentage of deterioration is acceptable at a one-year warranty inspection of water tank linings before a contractor must repair the coating job?

Selected Answers

From Erik Andreassen of CFPS on August 25, 2011:
     No percentage is acceptable where an internal lining has been carried out. The warranty should have been a back-to-back warranty with the coating supplier for at least 3-5 years, but once defects are found, it is better to up-grade and replace the complete system. Request a report also from the coating supplier, as to the cause of the breakdown after such a short period of time.

From Keith Holdsworth of Eastern Tank on June 2, 2011:
     It's not uncommon for some areas to show after one year of service, especially if the previous substrate had extensive pitting or rough surface due to corrosion. It is important, however,  after  one year of service, that the lining is inspected and areas found are touched up, repaired and retested to ensure adequate repairs were made. Holiday testing isn't always 100% perfect, especially in extremely large vessels with prior steel deterioration.

From Steven Ivanick of LA City Depart. of Water and Power on June 2, 2011:
     You needed to include in your specification a one-year inspection warranty to repair all holidays that are present after one year. You should also install a CP system to get maximum life out of your steel water storage tank. By monitoring your CP system, you can determine how well your protective coating system is doing.

From jesse chasteen of schriener construction on June 1, 2011:
     If the final inspection was done correctly and meticulously, you should expect zero deterioration after one year service life. Most coating manufacturers stand by their product for at least one year and warrant product to provide serviceability for that time frame if applied correctly.

From Billy Russell of D&R COATING INSPECTION on May 31, 2011:
No percentage of deterioration is acceptable at that point.

From Tom Schwerdt of Texas Department of Transportation on May 24, 2011:
Zero.

From remko tas of Futuro SRL on May 23, 2011:
     No deterioration is acceptable after one year in a steel water tank below the waterline, and repairs should be done inmediately. If not, damage to the sustrate will only get worse at a fast pace. Above the waterline, you could apply some flexibility for minor flaws.

From Lalit Mehra of Quality Linings & Painting, Inc. on May 23, 2011:
Zero.

From Daniel Luder of Woodside on August 23, 2011:
     Zero. Heavily corroded areas should be mapped and brought to the owner's attention to allow for substrate repair prior to coating application. If no remedial actions are taken at this point, it remains a weak point. A paper trail is important in case people leave jobs. Each tank will have a inspection record file with all local wall thinning recorded for compliance with I.E. API 653 CODE.
