Has anyone cleaned garage floor epoxy off of cement

Hey Gang,

One of my customers flagged me down in the subdivision today and asked about a stain he has on his driveway. He recently had his garage floor epoxied and when they were packing up, they spilled some of the sealer on his driveway.

I looked for any past posts that might help (found tidbits in Parking Garage with Epoxy Floor Issues Parking Garage with Epoxy Floor Issues over in the commercial section, but nothing about anyone removing a sealer spill, mainly just discussing issues when cleaning the surface.

My initial thought when talking to him was perhaps etching the concrete, but itā€™s unclear to me if that would impact the stain to remove it or not. I know that if we were to etch those sections, the entire driveway would need to be etched in order to match, but wonder if anyone else has any other ideas. I thought about gasoline or a propane torch which Iā€™ve seen work with some grease spills, but not sure if anyone else had run into anything like this.
Here are a couple of pics I took today - I washed this driveway about a year ago - not really dirty in other spots, but this looks pretty toughā€¦


Heā€™s talking with the contractor about what they are able to come up with, he just asked me to get some ideas of what I thought it might take to get it done. I offered to try a couple of test spots, but he suggested we just let the contractor deal with it for now -versus ā€˜owningā€™ part of the problemā€¦

I donā€™t know what it is with these people. I got a call from an elderly guy in the neighborhood that wanted his old nasty painted deck boards ā€˜stripped of paintā€™ so he could repaint. A lot of them were so rotted I could put my heel into them.

Thanks for the laugh visualizing this.

Unfortunately, some old people donā€™t hold up well and tend to rot. I donā€™t recall ever putting my heel into one, but I can appreciate the sentiment Chris! :rofl: :joy:

FInd out what the base is of that sealer. I know nothing about epoxy stuff but for example acrylic high gloss sealer for pavers is xylene based, so you get some xylene, soak it all down and wipe it up.

!Thanks - it is high gloss thatā€™s a great idea!

for epoxy I would think acetone, but who knows. Not all garage floor coatings are the same, some companies lay a base then put epoxy overtop, some use another coating a poly something or other I canā€™t remember. The contractor knows what they spilled. I would walk if it wasnā€™t a good friend/relative. If you want to try, I would think scraping, apply acetone, wait a short bit until it loosens, then rag. Getting it out of the pores, man, what a PITA. Good luck to you and post after pics with your process if you try it.

Yeah - will have to see. Weā€™re gonna wait till the contractor comes back with something before doing anything and making it ā€œourā€ problem. Depending on what we do, it may look different so would need to do entire driveway. Good point on the type of sealer - Iā€™ll remind him to get the brand/type of epoxy from the contractor.

Wouldnā€™t worry about. Surely the contractor knows if theyā€™re legit.

I think he wants the contractor to pay but hire me to clean it. I wash his house and another house he owns in the neighborhood. This has been a rough year for me so Iā€™m grabbing whatever I can.

Yeah, Iā€™m with @Racer 100% on not touching it.

We have another company that I dealt with setting up a little bit, so I learned some of ths stuff. I know they use primarily polyaspartic coatings. They grind the concrete down first to get good adhesion, but Iā€™d imagine a driveway would likely be similarly rough to take the product.

They use Acetone & Xylene for cleanup, because I have to buy it for them from my supplier. But I also know the couple spots theyā€™ve spilled in the showroom and their truck are still there, so not clear on how well that stuff works at cleaning it eitherā€¦

IDK if any of that is useful, but itā€™s what Iā€™ve got. :rofl:

Thanks - I totally agree - I donā€™t want to own that problem. The customer mentioned that they tried some sort of cleaner, which he said didnā€™t work - then one of the guys pulled the cement grinder out to which the customer said - no - no - not on the middle of my driveway. So my suspicion is they have no clue how to remove it. Iā€™m thinking the contractor might want to turn to a pressure washer to clean it and pay them instead. This is why Iā€™m interested. If some of these suggestions will get it starting to move, maybe I can etch it (and the rest of the driveway so it matches) and get some work out of it. Not sure that etching is the right answer either just thinking out loud.

I donā€™t think anyone is going to pay enough for what that will take to make it worth the riskā€¦

They could likely do his whole driveway, in a similar color, to make it workā€¦but thatā€™s a lot of product, lol

Thatā€™s a good point. Iā€™ve been grabbing what I can as this year has been a bust for me, although this might be a ā€œbetter to walk away fromā€ situation.

Never make a bad situation worse by getting deperate (unless it is truly desperate, like ā€œabout to lose my houseā€ desperate), and even then it may not be adviseable

Funny you should say that - already lost the house - will be outta here by end of October, looking for a place now. As I said, itā€™s been a lousy year. I just signed up with a handyman service this morning for at least the upcoming months. Hopefully will pick up washing again in the spring. Lemme know if youā€™re hiring - Iā€™m a free agent at this point!

:grimacing: sorry brother! But, definitely wouldnā€™t take this one on, since that is past thenā€¦

Iā€™m always hiring good people, but itā€™d be a bit much of a commute, lol

Sorry to hear that. Do you mind if I ask a few questions?

Do you do wood at all? Do you paint? I donā€™t know your area, but I have had nothing but complaints from people about not being able to hire painters. I donā€™t want to go inside peopleā€™s houses anymore, but with my knee getting a little dodgy I am thinking about nixing the outdoor wood and moving inside.

On a side note, HVAC is booming. The driveway sealers are making bank, maybe hook up with one and do their prep and clean so all they do is spray. I sometimes help out a painter or two by doing their prep work.

Good luck to you. If it is any consolation, I have had 3 new people in my super small area start PW businesses. One is washing by hand.

Yes - I paint, mainly interior with drywall repair, and have been ramping up the handyman work all year with the lack of pressure washing jobs. I really donā€™t mind washing wood, but staining/painting decks it is not something I really enjoy. I have spoken to a few painters here, but most do their own pressure washing and prep.

I like building furniture and would really like to find a place where I could set up my woodworking shop again - I will miss having a shop this winter.

Iā€™m in North Georgia. Iā€™ve had some large repeat customers this year, but there is a lot more competition here this year than last and I think Googleā€™s proximity algo messed me up a bit as well.

I just met with a handyman franchiser today and will consider doing some work with them which will, if nothing else, provide a steady source of work at least and allow me to fill in gaps between what I can get on my own. I really do love washing with that 8gpm though - the best word I can use to describe the noise from the turbo nozzle on that thing is ā€œangryā€!
