Learned the hard way about wet curing polyurethane sealer

Poured a garage floor last Thursday and used a polyurethane sealer but forgot to check the humidity. It blushed bad in a 20x30 section and now I gotta grind it off and redo it this weekend. Anybody here use a wet cure method on polyurethane or just me?

...and here I thought I was the only one dumb enough to try wet curing polyurethane. I did a similar thing on a patio a couple years back. Mistook the humidity reading on my phone for the actual job site conditions. Let me tell you, that grind and redo is a pain but at least you caught it before the sealer fully set in.

Read somewhere that humidity sensors on phones are basically garbage for that.
