    Im sealing in the rain....just seaallllling in the rain.... lol

    I sprayed a job this morning (asphalt was dry) and right after I finished a light rain shower started. It went on like that for like 45 minutes until it started to pour. It was pouring for like an hour. Will this have an effect on the sealing job? BTW, it is supposed to get warm and sunny later on in the day.

    What is the rule of thumb when it comes to rain and sealing?

    How bad is it if I spray a driveway that is a little wet?

    Unfortunately for you, plan on resealing. Rain will wash it all off. Wet pavement will make the sealer flow if it is too wet. do not seal with rain in near future.

    I sealed it at 8am. Went back to check it out at 7pm and surprisingly it looked fine! I guess it being an oil based sealant it didnt cause any problems.

    With oil base sealer (Gilsonite,BlackMax,..whatever) it can rain on it after about 30 minutes on a warm day.

    The asphalt has to be totally dry before you seal. That means turn off your A/C on the way to the job because if water is dripping from your truck onto the asphalt to be sealed it won't stick well in that spot.

    Thanks Dintlow,

    I figured that it would be safer to have rain fall on the driveway after sealing it rather then sealing a wet driveway.

    I never understand the part of a "sealer" being made out of water.. lol

    Black Mac on the other hand is hydrophobic. It does not mix with water, therefor the asphalt has to be completely dry, then you spray your driveway, take a bottle of water and empty it on the driveway (I do that to some customers who don't believe me) The water will just bead on top, even if it rains 2 mins after your done or 1 day, it doesn't matter, it won't wash away.

    I concur! I am living proof of that as well. The driveway looked the same as if it didnt rain.

    JF, There are some frickin lines on the driveway though! They are gonna be there for a long time arent they?

    I may have to go back to that house and re-spray :(

    Will I get a more uniform result if my pressure is adjusted higher? I typically spray about 2ft above the asphalt.
