Is there a place for using “rust convertors” in heavy-duty maintenance projects?


Selected Answers

From john schultz of o-gee paint co on January 11, 2017:
There was a blog post, here or on D+D, not that long ago where the author had pictures of crumbling steel infrastructure around New York. Another one bemoaned the problems with maintenance on offshore rigs. In both blogs, the maintenance was put off to the point where structural integrity is destroyed and big pieces needed replacement, a process well in excess of the cost of maintenance. If something like a rust converter can be used in a maintenance regimen to band-aid an area until a proper recoat can be implemented, then there is a place for these things. Like a shop primer, it would be there until it is removed for application of the heavy duty maintenance coatings.

From Per Gabrielsson of Free Lance Consultations and Inspections on January 11, 2017:
Simon, I presume (and hope) that any quality-oriented coating manufacturer would tell a client that their highly engineered coatings are intended for duly prepared surfaces only and then courteously refuse to supply. Is this in line with the thinking of your company?

From simon daly of Hempel A/S on January 11, 2017:
Yes. It is a fact that clients' budgets are often constrained and annually calculated and in some cases results in work being deferred. Where the alternative is reduced cost because of a lower level of surface preparation, which subsequently allows work to take place which would otherwise not have done, there may be a case for accepting a lower level of durability associated with reduced surface preparation. It depends on numerous factors, including the client's corrosion prevention strategy, life of asset, available maintenance budget etc. Provided expectations are clearly defined and suitable working practices and QA/QC are implemented, these materials MAY provide a viable route.

From James Prevatt of SPEC-GUARD on January 10, 2017:
The basic rule of preparation is to provide as clean a surface as possible to enhance an better bond for the first coat of specified material. Most specifications require removal all contaminants including those seen and not seen. Surface rust is a contaminant among others. For surfaces where higher preparations are not possible, a 'rust converter" might be considered as a last resort. The process requires first using mechanical and power tools to remove all loose rust to a SP-2/3. If you can achieve an SP-11, no converter is required. Test for salts suspected for the environment and treat. Finally, solvent wipe and you are ready to apply the "rust converter." Some require a rinse, and some do not. Apply per the directions as excess will most likely result in disbondment. Lots to remember and enforce, but the cleaner the surface the better the application. If long term performance is the goal, use the higher level of preparation methods, and "rust converters" only when higher levels are not practical. Never use a rust converter because it is cheaper, which is a fallacy when the life of the coating is accounted for in the consideration.

From Tom Schwerdt of Texas Department of Transportation on January 9, 2017:
No.

From Warren Brand of Chicago Coatings Group on January 9, 2017:
Typically, no. Although, never say never. I can envision scenarios where, say, abrasive blasting and other surface prep procedures are not allowed, or there are severe time constraints, and the only viable option is some type of rust convertor. It would, however, be a last resort.

From Paiboonsak Saengsomboon of JT Marketing Co., Ltd. on January 9, 2017:
I have never seen a place!

From Per Gabrielsson of Free Lance Consultations and Inspections on January 5, 2017:
No!
