I just applied a second coat of Ultra-Maxx 10 year sealer to my driveway today and 4 hours after I finished it started to rain. It's a fast-drying urethane asphalt sealer that is foot traffic ready in one hour and my fingers are crossed, but how F'ed am I? Am I gonna have to power wash and start over? I won't be able to check on it until tomorrow afternoon, but I'm scared/pissed. The Weather Channel app on my phone says there's a 0% chance of precipitation, LOL!

Here's the stuff I used: Shop BLACK JACK 4.75-Gallon Blacktop Driveway Filler and Sealer at Lowes.com

 

I was looking at the product spec sheet. It's a water based product. You should be ok. The spec sheet says two hour cure for foot traffic. At four hours it should be cured enough to be rain resistant.

How did it look after the rain.....was it soft or runny ?

 

I left before it rained. I won't be able to check on it until tomorrow afternoon. First coat was done yesterday. Today's second coat was dry to the touch a few hours before the rain, except fomen aye some slight pooling at the edge of the driveway where it meets the grass (I'm not too worried about that, though).

The container says the dry time for foot traffic is one hour. Where'd you find the spec sheet? Lowes.com only has a general "Product Info" page, but it's not specific to this type/brand.

 

Ah, just found the spec sheet. Fingers are crossed!!!

 

The 2nd coat always dries slower than the first because it lays more on top while the 1st coat is able to be sucked into the asphalt. Even if the 2nd coat is degraded by the rain it's doubtful you'd need to PW and start over. A 3rd coat of sealer with good drying conditions will normally fix it.

keeping fingers crossed

 

Just an update for anyone interested:

The driveway was, for the most part, dry when I checked on it this afternoon. There were a few puddles in low-lying areas which I blotted up with paper towels and blew dry with a leaf blower.

When I rubbed my finger on the non-puddled areas, some black residue ended up on my finger, although I'm not sure if that wouldn't happen even in ideal drying conditions. When I rubbed the puddled areas there was definitely more sealer residue coming off, but nothing too gooey. I'm not going to use the driveway for at least a few more days just on the off chance that helps.

My main concern now is tracking, as I'm having 1,800 sq/ft of carpet installed next week.

 

Thanks for the update. Sounds like you should be ok.

As far as the carpets.......tell the rug guys to leave some scraps for runners. Use them until the driveway is good and dry.
