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


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


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


If a zinc rich epoxy primer has been applied at lower than the specified thickness, how should this be treated?


What is the correct gauge type and probe for measuring coating thickness of a super duplex stainless steel system with epoxy and polyurethane?


When applying a 100% solids, fast-curing polyurea coating on concrete, what is the best method for verifying that the proper thickness has been applied?

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


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"?


On a recent project, complex pre-fabricated, hot-dipped galvanized panels exhibited thicknesses in the range required for the entire subsequent coating system. It was not practical or possible to accurately map the thickness of the galvanizing across all the various parts, and DFT gauges available only measure the entire non-ferrous coating, including the galvanizing. How should thickness-per-coat minimums and maximums be controlled and verified for subsequent coatings?


If an atmospheric coating system of a zinc-rich epoxy, epoxy mid coat and polyurethane color topcoat has properly cured with no visual defects, should I be worried if the thickness of any coat exceeds any specified maximum?

How many times can a building be repainted before the paint becomes too thick to perform properly?

What is best way to remedy over-thickness of a topcoat after it has dried and cured?


How does one determine if concrete is sound enough to receive a thick-film coating?


The literature indicates that UHP waterjetting produces a profile on steel, although of a micro nature. Is this sufficient roughness for good adhesion of thin-film primers?


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.

What is the best way to remove thick-film elastomers from floors and ship decks?


How does one accurately measure coating thickness on the inside and outside of a small-diameter (~50mm) pipe?

If a paint data sheet notes a required primer thickness of 125 microns, but the project specification calls for 50 microns, how is this resolved?


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

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?


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


If I apply a zinc-rich epoxy primer at 3 mils’ dry film thickness in the shop with air temperature of 90 F, what checks can I make to determine when it is safe to handle and stack the primed steel components?
