On a commercial pressure washing job today for a regular customer. The manager said it but i didnt pay attention when I got the message that he’s really most interested in getting the gum up. I don’t get too many requests like this so I never researched it fully. Now I’m in a little bit of a jam where I need the answers asap. Anyone with any experience with gum removal from concrete?
Yeah, ,actually I’ve got one parking lots worth a long time ago. I didn’t use soap and the boss brought his pressure washer in from home. It was chipping concrete out from under the gum. He came back when I was done and was a little on the other side of happy let’s say. Little divots all over his parking lot… I only saved my job by saying “At least I make bad ass donuts” lol. That was a long time ago. Kk, story time over. I’m sure your getting what I’m saying.
Goof off and a scraper or putty knife. Let the goof off sit for a few, scrape then wash off.
You really want hot water. I do this every week.
25 or 40 degree tip. 25 preferably. Definitely not 0, but i think you know that. Just had to say it.
Just be careful of etching it. Especially if you are using cold water.
Anyone ever try this?
Yes…not that exact product but I cleaned carpets years ago and used a freezing spray like
that on gum and it worked well. I think hot hotwater with your pw would do the trick or prespray with a solvent of some kind.
So @IronLionZion what process did you use on the gum removal and how where the results?
I wasn’t able to get it off with my cold water machine.
You need hot water.
I tried so many things on one of the first ever commercial jobs I did so I didn’t have to spend money on renting a hot water unit.
Cold water PW nearly parallel with the ground to get underneath it.
Heat gun and putty knife.
Then I sucked it up and rented a hot water unit after making next to no progress and wasting 8 hours on a “strip” mall with two units. A beauty supply and a discount cigarette place absolutely littered with gum.
Rented the hot water unit and made all of $50 bucks because I bid the job wrong. Way wrong. Anyway, long story short it took me about 90 minutes with a rented hot water unit. Kinda embarrassing to think about now actually.
Hot water pressure washer is the only real answer.
