We recently had some acid staining done in our home. I'm trying to get a sense of whether this was a job well done or not at all. The outcome certainly is not what I was expecting. My concerns are:
- in some places the stain appears washed out. Like it didn't absorb.
- the stain looks like blue chalk in parts. It looks like there were just spills on the cement.

I've attached a photo that trys to capture the look. My question here is was this a botched job?

Thanks for any insight you have!
