Rule of thumb after floor prep

[Jaguar Fan]

After floor prep (lots & lots of water used in degreasing, acid etch, power washing, power washing more, etc etc)... is there a rule of thumb for about how long to let a slab dry before you think it might be ready to put on a primer coat? Of course, the ultimate test is to tape plastic down & see if there is condensation ... but do you have any rules of thumb? e.g., 2 days? a week? more?

Thanks

I left mine for 2 weeks and did not do a tape test.

I coated mine the next day and I havent had any problems. I made sure that I squeeged everything the day before. You are probably better off waiting a few days though.
