What is the best way to assure compliance with specified dry film coating thickness requirements on vertical concrete?

Question posted October 23 to October 29, 2016


How should a contractor respond when he/she reads a specification requirement that "the nominal dry film thickness of the coating shall be 3 mils"?

Question posted June 5 to June 11, 2016


How does the concave or convex curvature of a surface affect the dry film thickness reading?

Question posted October 16 to October 23, 2015


How do you calibrate a DFT gauge in the magnetic field of a live power plant to measure coatings on steel substrates?

Question posted March 16 to March 20, 2015


A specification for a bridge to be built of high-performance weathering steel requires an SSPC-SP 10, a profile of 3 to 5 mils, and metallizing with a final DFT of 10-12 mils. What challenges, time, and costs are associated with obtaining the profile?

What is the best way to assure compliance with specified dry film coating thickness requirements on vertical concrete?

Question posted September 29 to October 3, 2014


How do you measure wet film thickness on shop-applied organic zinc-rich primers to accurately predict dry film thickness? Our shop applies a great deal of OZ primer, and we have found that WFT readings with a standard gauge are not accurate predictors.

Question posted August 18 to August 22, 2014


What generic types of coatings work best as liquid-applied air barriers, considering both cost and effectiveness, and what should be the dry film thickness of this system?

Question posted July 21 to July 25, 2014


I have several 20-year-old carbon steel tanks for storing demineralized water. The original coating (type unknown) has started to blister. What material, at what DFT, should be used to refurbish the coating?

Question posted April 21 to April 25, 2014


What do you do when the surface profile is higher than the dry film thickness of the specified primer?

Question posted March 10 to March 14, 2014


What errors are most likely to occur when measuring dry film thickness on steel, and how can I avoid them?

Question posted November 18 to November 22, 2013


Where are errors most likely to occur when measuring dry film thickness on steel, and how can they be avoided?

Question posted August 19 to August 25, 2013


How does the concave or convex curvature of a surface affect the dry film thickness reading?

Question posted May 6 to May 12, 2013


How do you measure the DFT or WFT of a film-forming sealer applied to a metallized coating (e.g., flame-sprayed zinc)?

Question posted November 21 to December 4, 2011


How do you calibrate a DFT gauge in the magnetic field of a live power plant to measure coatings on steel substrates?

Question posted September 26 to October 2, 2011


Which DFT statistics should be recorded in a daily inspection report, and why are they relevant to a good coating QC record?

Question posted June 20 to June 26, 2011


How do you measure wet film thickness on shop-applied organic zinc-rich primers to accurately predict dry film thickness?

Our shop applies a great deal of OZ primer, and we have found that WFT readings with a standard gauge are not accurate predictors of DFT.
