Building Wash: Stumped with stains on wall

Good afternoon everyone,

I received a call from a restaurant owner stating he needed me to pressure clean his restaurant in order to have it ready for paint. Upon my arrival I immediately noticed several "scuff marks" on the walls. After speaking with the RO he stated to me that he originally had another company come in to pressure clean and they were unable to complete the job. He showed me the stains I was originally looking at and stated the the company before used chemicals and even a brush and were unable to get it off.

I did a walkthrough of the exterior of the building and something I noticed that was common with all the sides of the building. Every area where these marks were on the wall were short tree shrubs. From the looks of it, it seems as if they were using a tree trimmer and while trying to get everything squared and even they kept rubbing the trimmer on the wall.

Like I said that is what it seems to be but maybe I am wrong. Can anyone chime in and give me some feedback on what they think it might be and how I can go about in removing it? Any help would be greatly appreciated.

Thanks,

That looks like rub marks from trees or bushes before they were cut or trimmed down. They blow back and forth and scratch at the paint or oxidation on the paint. Doubt they are organic. Just take a strong mix and do a test spot and you will see. Ask if the landscaping has been trimmed down or replaced lately.

Agreed!

Try Wesleys Tire White. Buy it at an auto parts store. Works great on mud dauber stains too.

I have tried a few like that and in my cases, the stains were rubbed into the paint and the paint would come off with the stain so the only solution was to re-paint.

Good luck.

Let us know if you have any success.

Winner! We see it all the time.
 
If you are washing it for them to repaint, I wouldn't worry bout the stains. If it don't come off with a pressure washer and lil soap, paint will stick to it! Main thing to worry bout in paint prepping the surface is getting all the oxidation and any mold or mildew off. We do a lot of paint prep work in the summer.

I agree as well. Painting will prob be the best option
 
Once again thanks for all your help everyone. I asked the client about trimming lately and they stated they were trimmed down to to wanting to paint the building so that makes sense now that I see it. After throwing ideas back and forth the client stated to just try and get as much off as possible and if it cannot be removed that it would not matter too much as the building is being painted. Going in next Monday to do the building wash to get it prepped up for painting.
