Anyone gotten cracks in their shops concrete floor from using red heads

[tackit]

Not that i know of

From what I have been told they used a certain kind of sulfur to hold railings in place in the old days. I think my front stoop railings were done with it. I replaced cheap rusted steel railings with treated wood railings to give a more country look but I never tried removing the sulfur for fear I might crack the concrete. My home was built in the early to middle 70's.
