So how long do I need to lay down sealer before it rains?
If it rains say... 4-5 hrs after I applied the sealer will it effect the outcome of my driveway????
Im using Blackmac sealer :canadaflag::canadaflag:

We did a bunch one day last year that was forecast hot and sunny. While we were doing our last one it started spitting while we were spraying and shortly after it came down hard. I went back a week or so later and it looked fine. I was driving by jobs from the last couple years 2 days ago and the ones that got rained on are fine. That being said, I really don't have a technical answer to your question..... :drinkup:

If it rains while sealing, you may get air bubbles under the sealer, that will flake off. It the rain is on-top of the fresh sealer, you should be ok, but sometimes you may see white streaks, or marks in the sealer. I've had one job done only minutes, before a downpour. I feared the worst, but checked it the next day, and it was fine.
