How Long after etching to apply epoxy?

[machwon169]

About to do a big project.... 50x50.... how long should I wait after etching the floor to apply epoxy? I'm using muratic acid and brush.... then baking soda and water... then power wash it.... then let it dry... it is in the 80s most of the days....will push most water out...

Should I wait 24 hours, 48 hours, a week?

Pressure wash? 4-5 days to be safe. Can do a plastic test to be sure is dry on the last day.
We use the same fans that carpet guys use (air movers) to dry a floor much faster.
Any source of air movement is great.

Agree, do the plastic sheet test. Usually 24-48 hours is sufficient.
