Problem Solving Forum (25)


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


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


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 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 assure compliance with specified dry film coating thickness requirements on vertical concrete?


How should a contractor respond to a specification requirement that “the nominal dry film thickness of the coating shall be 3 mils?”


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?


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


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


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)?


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?

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.


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?
