ᐅ Removing adhesive residues from exposed concrete ceilings

I could cry and really hope someone here can give me some advice.
We have modern exposed concrete ceilings on the ground floor of our house. We masked them ourselves for the plasterer using plastic sheeting and painter’s tape. Then, quite cleverly, we thought we might as well leave the masking on for the painter too, so they wouldn’t have to mask the ceilings again.
Unfortunately, the painter didn’t come until more than a month after the plasterer...
Well, last week—now that the painter has finished—we removed the plastic sheeting, and I almost had a breakdown: the tape left unsightly marks on the exposed concrete ceiling (see photo above). Unfortunately, these marks can’t simply be rubbed off. It seems as if the adhesive’s solvent penetrated the porous concrete. Even my husband’s attempt to lightly sand the ceiling only made a minimal difference. What now?! I’m hesitant to try any common adhesive removers on the ceiling because I’m afraid the oils they contain could cause even more damage.
I’ve searched online extensively, but somehow no one has been able to help. Maybe someone here has some advice?! It just can’t be true that we’ve ruined our new ceiling because of this carelessness?! I’m grateful for any help!

Hello,
we started with very little paint; after the first coat, you could hardly see any effect. We now have 5 layers on it, and I would say hardly anyone who doesn’t know the wall was painted or glazed notices it. With a primer, I would definitely work on visible concrete (to avoid using the term architectural concrete here) to seal the surface and prevent any sand release. This was a tip from a painter friend. By the way, highly expensive “concrete cosmeticians” treated our neighbors’ concrete carport in exactly the same way, but in my opinion, they used too much paint...
But before that, you should really try to find someone who can help you with removing the adhesive residues.
I do not recommend sandblasting for this, by the way. We only tested it once in the basement. It opens countless pores in the concrete, and afterward it looks like a slice of Tilsiter cheese.

Is there any update here? Have the adhesive residues been removed?
And I just read that you agreed on exposed concrete quality with your builder... Actual exposed concrete? Aside from the adhesive residues, the rest doesn’t really look like exposed concrete either. That was also the reason why the concrete finishers had to come to our neighbors’ place (at the builder’s expense), because exposed concrete was agreed upon but was not delivered.
