Besides myself (Robert, taking the photo), here are our three workers for this project. On the right is Kathy Childs, who has a watering can filled with muriatic acid, which she sprinkles onto the concrete. In the center is my brother David, Kathy's partner, who then scrubs the acid into the concrete. On the left is Judy, our production manager (taking a break from the studio). She is neutralizing the acid with an amonia mixture.As the concrete was six months old, we had to clean it and open the pores so the polymer concrete would bond to it properly. The yellow haz mat boots are quite a fashion statement.
