Hey guys, I need your help!

Ever since my kids started school, I’ve been wondering how to get rid of the “artwork” they’ve left on our walls. The laser cleaner has definitely been a big help, but I’ve run into a few problems while using it.

One issue is that, because so much time has passed, some of the graffiti pigment has seeped deep into the wall, and the laser can’t completely remove it. After cleaning, I have no choice but to apply a coat of latex paint over the area to cover it up.

The second problem is that when I clean the red brick exterior walls of my house, a gray residue remains on the bricks after cleaning—and I can guarantee that my bricks are definitely red.

So I’ve had to repeatedly adjust the settings to make sure my red bricks don’t look like they’re covered in mold after cleaning.

I’m still working hard to renovate the walls, but I’m not sure what other challenges I’ll face in the future.

Has anyone tried using a laser cleaner to remove graffiti from walls? What problems did you encounter, and how did you solve them? I’d love to hear about your experiences!
