I probably added the most fuel to the sandstone fire, but was trying to keep it completely apolitical. Asked and (since I know how to clean sandstone) answered, simple as that. At the risk of venturing into politics, I felt, but didn't say, that cleaning the sandstone might be one of the most important things about this incident, particularly when you read about reaction to what the graffiti says. They've already covered it with something like butcher paper judging from the Page 1 article in today's paper. They defaced an engraved memorial to service members who died in service to their country. The graffiti needs to be permanently erased.
And to complete the SSPC (NACE International/Society for Protective Coatings Joint Surface Preparation Standards) loop, because I know you are all rivetted by the topic, there is indeed an SSPC - SP11. That's Bare Metal Power Tool Cleaning. Used where abrasive blast cleaning is not possible. Still down to a surface smoothness of 1 mil (25 microns). In fact, SSPC goes all the way to SP16 - which is Brush-off Blast Cleaning of Non-Ferrous Metals, which now that I see it in print again, I'm sure I've specified at least once. We just spec whatever is required per the coating manufacturers.
I have a good friend who retired as a mover. He parked his large moving van on the street in the Sunset. Tags over tags over tags. All exposed surfaces including the roof. He gave up trying to clean it. Then suddenly no more tags. He was at a job in the City and a passer by told him that he should be honored to have so and so's art work on his truck. "Huh" "Yeah, no one tags over so and so." There's a code, you know.
I mean my going for king of all paint preparation specification nerds is sort of an actual discussion, right?
Right. I can be guilty of overreacting. This perhaps. was one of those times.
