Knigge-Bruce adds, “Getting a three-dimensional effect with polished concrete is tricky because you are generally going to apply dye midway through your grinding steps. If you were just sealing over the top of the artwork, you could create pretty much anything and the sealer would lock colors and shades in place.”
While Knigge-Bruce says the biggest challenge on this design was achieving the right effect without losing detail in the end, for Cunningham and his polishing crew it was working in tight quarters around other trades and contractors installing the exhibit’s large aquariums. But in the end, the creativity of the artistry team and the expert finish from the polishing crew offered an interactive floor that enhanced the visitor experience.
