We have a huge driveway and patio done in colored, stamped concrete. The install was about 3 1/2 years ago the concrete was supposed to be colored prior to pouring. Unfortunately, the concrete installers were not careful about matching color batches, so areas definitely have distict differences in color. We have removed the sealer and are ready to put a semi transparent stain over the top, in a new, complimentary color. The question is, are there concrete semi transparent stains that are better or worse?

We hate constantly fixing things. We are looking for quality and reliability.

The weather here in central coastal California - winter, cold and (hopefully) wet, night temps in the low 30s. Summer highs typically in the 90s extremely low humidity.

Any suggestions, please!
