Remove adhesive residues from exposed concrete ceiling

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 barely anyone who doesn’t know that the wall was painted or glazed recognizes it, I claim. With a primer, I would work anyway with visible concrete (so as not to use the term exposed concrete) to close the surface and prevent any sanding. That was the tip from a painter friend. Sinfully expensive "concrete cosmeticians" treated our neighbors’ concrete carport exactly the same way, only in my opinion they used a bit too much paint... But before that, you should really try to find someone who can help you regarding the removal of the adhesive residues. By the way, I cannot recommend sandblasting for that, we only tried it once in the basement. It opens an endless number of pores in the concrete, afterwards it looks like a slice of Tilsiter cheese.

Is there anything new here? Are the glue residues gone? And just now I read that you agreed on exposed concrete quality with your house builder... Actually exposed concrete? Apart from the glue residues, the rest doesn’t necessarily look like exposed concrete either. That was also the reason why the concrete cosmetic specialists had to be called in at our neighbors (at the expense of the construction company), because exposed concrete was agreed upon but was not delivered.
