It's currently 34°F outside. I'm waiting for the sun to warm the house to the lowest recommended temperature for application, 35°F. Second coat. Really regretting getting fancy with accent colors.
You should get yourself a beer - an essential tool in these types of preparation on a Saturday.
Also, when your thermometer says 35, how do you know that it's actually 35 and not 34.9999999? Might wanna wait until 36 to account for rounding errors.
And unless you have a scientifically accurate thermometer, giving it another degree is probably a good idea.
And on top of that, just because the ambient air reads 37, it doesn't mean your patio is, so you have to account for that too.
Ergo, you should wait until at least 38. Plenty of time to kick back and "inspect" your "tools"
