Cement patio

Any tips to even out the splotches on this patio. The discoloration is from moss being removed.

How did you clean it?

Cold water surface cleaner with a light degreaser mix. The moss and dirt came off great. The discolored splotches were under it. She was happy with the job but I’m not. I wanted to know if there was a way to get it all back to the color under the moss.

You could try SH with a pump up or dedicated pump and lay it on strong but I think the surface cleaner would have cleaned the dark colored areas without the SH.

Its gotta be a crappy sealer that’s on their good. I ran into something similar last year and the guy said he used Thompson’s water seal on it 3 years before. I’m betting that’s what this is. I knew I should have passed on this one. Lesson learned.

If you want to go back do a test with some sh in a small spot. If it comes cleaner than you know what to do.
