it's unclear what you are talking about. shadowing? be more clear. sometimes if objects are left on new concrete for long periods of time, the concrete will cure darker in those areas. there is not remedy to that except to use a coloring agent that is more like a paint than a stain and will cover it up. or you can do a skimcoat or microtopping overlay.

Direct heat may be the answer...or not.
I do a lot of demos and testing using Scoring Tape, this is a tape used instead of chalk line, it looks like grout tape but it has a black line running the full length of the tape right down the middle. You place the tape on the floor and then use the line as a guide to score your lines. What I have seen is that where you place the tape it leaves a darker line on the concrete on the places you do not score, probably from drawing moisture to that spot, where you score the concrete there is no dark spots probably because the high heat generated by the blade while cutting the concrete, this has always made me very curious about this and I tell people when I show the tape to place the tape and then cut the excess on all the place where there will be no scoring and leave on just the pattern to be cut, after you score you remove the tape and there are no marks anywhere.
Now, would heat be the answer?, I am not sure but it could be.
Do a test with a heat gun on a spot and see what happens.

the staining looks good but i don't like the marks. if you used a solvent based sealer, those cuts would have darkened up - they'd be black instead of white - and the color of the floor would be deeper as well, making it harder to see those marks.

here is a better pic of the bad spot. I guess there is no way to really fix it... overlay it I guess

no, it's not worth overlaying. it looks good overall. i just would have used a different sealer. a lot of builders and homeowners would try to hold you accountable for those marks and not pay the whole bill, even though it's not your fault. you did the best you could.

So you think that next time a solvent based sealer would be a better fix. I will log that into memory thanks
