If the original finish was actually a product made for coating (staining) concrete, power washing should not cause the finish to breakdown. I have seen cases where someone would use house exterior paint for the driveway with resulting failure a few years later. The result being that the old finish needs to be completely removed by grinding or sandblasting, and a new finish applied. All of our driveway, lanai and birdcage finishes have been power washed several times (1700 psi or less) with no damage to the finish. These are 2 to 9 year old finishes and all look good as new.
