Approximately 80 year old historic stadium with approx 15,000ft of original rock walls that they want to look like new along with cleaning the rest of the stadium. The rocks themselves starting to break down and I won’t even mention the mortar. Got lichen older than me on it. The funniest thing about it when I met with them today was that they had someone bid $2000 for the whole job. They laughed at him. I figure my soap and SH will exceed that. Going to take probably 3-4 applications before even thinking of washing it in places. @Atlas, want to come have some fun next week or 2?
