We have a LOT of bad stamped concrete work up here....it's great.

For this one, we used SoyGel to emulisfy sealer and release & powerwashed, removed 100% of the sealer and 90% of the release, all but the lowest lying areas. Sealed rock coping, then Chemstone Black at 7 to 1, neut/rinse & sealed with two coats of CSS 2:1. Two guys 8 hours day one to strip and stain, 2 hours next day to seal.
