Now my brother got me all worried about doing this myself in a limited timeframe... during the three or four days when I visit later in May. He cautioned that if the humidity is high or rainy outside that the concrete may not dry thoroughly enough after the etching. If you HAVE to do this when the humidity is high outside, e.g. over 80%, close the garage door, have a large fan blowing across the surface to dry it out, maybe with a dehumidifier running. Now this is the "iffy" part. Once it gets thoroughly dry, and it's still humid outside, and you feel a need to paint anyway with the garage door closed, you better wear an appropriately designed respirator.

Anyway, my delemma is should I plan a 200 mile trip for this purpose with the chance of it being too humid in mid- to late May. I will not apply epoxy with the garage door closed.
