Help on a asphalt driveway

Liberty SoftWash · Jan 12, 2013

Maybe go back and pressure wash the residue off.

Guest

It will eventually come off but not 100%. If you power wash it just use a wide tip and rinse it 3 to 4 times but it may or may not help. If you have some of ac's bleach wash try some in a inconspicuos place and see what it does. good luck.

It could just be salt.

We had this happen once, and it left permanent marks. I had the driveway professionally sealed - problem solved.

If asphalt Is what we would call Tarmac, then the bleach has "bleached" it.

The asphalt here is an asphalt binder (crude oil) added to aggragate (crushed stone). I don't think it is bleached out but just a residule leftover from the roof mix.

I'll try the recommended pressure washing route and if that does not work, I'll go with the well respected suggestions of Ted Saunders, Ed Thompson and Larry Millette to black top seal it, make the customer happy, everyone is happy, I get a good nights sleep and tommorow is another day!

Can I have an AMEN! biggrin

Newly sealed blacktop can be a problem for anybody that cleans with SH. We try never to even park on it.

I deal with Asphalt, blacktop all of the time. Anyone know when this is occurs? So far I haven't had any issues with this, but I don't want to. If I had to correct it, sealing is the way to go.

I have left those streaks on two driveways and got lucky no one complained. That being said, No matter what you have to keep them soaked with water the entire time .....never let up keep it moving. I rode by the homes from time to time and the stains did go away after about a month...I think the driveway just got dirty again and that covered it up. I agree just reseal it and move on....but when you pull up and see one and its in good condition to great keep her soaked! If its a crappy asphalt all messed up and beaten...I dont soak it just wet it ..it's shot anyway.

We always keep them flooded. And if it is newly sealed, we try to never park on it. But sometimes, the house is so far from the road you have too.

Bruce Weber · Jan 12, 2013

Most blacktop driveways have been sealed. Our mix has stained two freshly sealed driveways in the past year. We paid to have them re-sealed, which hurt. One re-seal job still did not cover up the stain. Things that I have learned:

1. If a customer just sealed thier driveway, reschedule the roof cleaning out a couple of weeks. If a customer is thinking about sealing a driveway, tell them to do it AFTER they get thier roof cleaned.

2. If a gutter empties out on a sealed driveway, divert it away from it when flushing.

3. Water like crazy, before, during and after. You read this over and over on this site because water prevents damage.

Thanks for the feedback guys. Went by this afternoon and hit it with a wide fan tip, 3800 psi (not held close to the surface) and it came out great. Customers happy, I'm happy, life is good! biggrin

You may want to try another runoff system. Here is a link to a runoff system I built that works great.

Click on video that says equipment and runoff system.
