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


How do you account for the profile of blasted steel when taking a dry film thickness reading?


How do you prepare flame-cut edges for application of thermal spray metallic coatings? The problem is that these edges are often harder than the abrasive, so a very low profile is produced, resulting in lower-than-specified adhesion of the thermal spray to the steel.


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?


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?


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


What is the remedial action if a blaster produces too high a surface profile for the required primer thickness?
