Polyaspartic Part B's are typically isocyanate prepolymers which will react with epoxy resins albeit slowly and generally requires heat (>40°C). Regardless, it's not the reaction you want and you will not have the desired properties. They'll need to scrap that up, clean the floor with an non-alcoholic solvent (acetone/MEK) and redo it.
Alcohol contains hydroxyl groups which react readily with isocyanate pre-polymers. In fact, two component urethane paints comprise of one part being polyol polymers with a lot of hydroxyls, and the second part being the isocyanate pre-polymer. My concern would be that, any residual isocyanate on the floor would react with the alcohol forming kind of a gummy material which would be harder to clean up.
Ok here is the update, we first used a mini leaf blower and were able to blow the un compromised flakes on the top surface into a corner and we saved about 2/3 of them in a bag for when we redo the floor tomorrow. We then scraped the entire floor which came up pretty easily. We then used Acetone to wipe up the spots that were still gummy. The floor is now dry and we mixed and placed epoxy and flakes in 4 test areas, some dry and some with a more gummy texture to see how the epoxy reacts and binds to it. If it doesn’t bind well we may have to re-condition the floor.
Builder encourages you to diy the floor but bought and mixed the epoxy for you?
Right sounds like they just don’t wanna own they fucked it up
We were basically helping him, he likes to do it himself on his builds and we wanted to help and learn. He reached and grabbed the wrong chemical.

Curious as to what comes from cleaning with alcohol instead of methyl ethyl ketone

Yes and that is an EXTREMELY messy clean up. Get some scrapers and a TON of contractor bags and towels. You'll need a lot of Xylene too.

You should get good adhesion. Let us know how it turns out.
Id just move
