This project took a lot of time to complete. We had to patch, hand grind and polish before starting. Once this was done the work started.
It was a 7 layer stencil with 19 different colors, this took approximately 12 hours to complete, one big problem was the concrete was very soft and when polishing we had to be careful not to cause dips in the concrete.
Once all the dying was done I used a polyaspartic sealer from HP Spartacote, Boulder Co.
