The floors of the Orpheum Theater (1921) needed refurbishing. The owners were going to remove the old epoxy and put down more. But they changed their minds when they learned about polished concrete and the RetroPlate system. Additional Concrete Services/Gopher State Cleaning, longtime Certified RetroPlate applicators was selected to perform the work.
The new seats did not have the same footprint as the old ones, so 3,000 holes on the main level ad to be patched before grinding could begin. But, the most challenging part of the main floor renovation was grinding the vertical faces of each seating section. Over 2,000 lineal feet of 6” – 10” tall faces were hand ground with 7” and 9” Metabo grinders, with vacuum hoses hanging from them. The ACS/GSC team burned up many hand grinders during this process.
The finished project, completed in two phases (main floor and balcony) over the span of one year, took a four man crew approximately 60 days to complete. The main floor was nearly 6,000 square feet and the balcony, approximately 6,500 square feet. Thousands of holes were patched and roughly 4,000 linear feet of risers were ground. The results were a class B/C, level 3, black dyed RetroPlate polished floor.
