Windy City Steam specializes in stain removal of many sorts. When it comes to blacktop sealer, it can be a real pain to work with at times. A local sealcoating company we have a relationship with had ran into a problem where they sealed a driveway and it didn’t have enough time to dry before we got hit with rain. This one was unfortunate because the driveway had plenty of time to dry, but the whole driveway is surrounded with trees which didn’t allow sunlight to hit areas up by the garage so it still splattered and made a pretty bad eyesore.
I remember this job like it was yesterday, I cleaned this up the day before the 4th of July so it was hot outside, a humid 100 degree day which makes our job a lot harder. You’ll notice on hot days like this that your blacktop is sticky and and tar areas become soft and will smear so you would think that it would make our job of removing it easier however that’s the furthest from the truth. It really clings to the pavement we are trying to remove it from no matter how much pressure we hit it with. That’s why we spray down the solvent to break it down and let it sit for a good 10 minutes. What you don’t see on camera is how fast it dries so I had to cover it a good 4 times in solvent just to allow the proper dwell time without allowing it to dry. We just end up going through a lot more solvents on hot days for that reason, but we are still able to get great results as you never want to let an oil based sealer sit on concrete for very long because your concrete will begin to absorb the oil out of the sealer below the surface and get to a point where fully removing it gets to be a process.
