My whole driveway is like that and so are most other driveways around here (it's a mountain) but I'd be really surprised if they did anything other than spray it with water. This isn't the sort of concrete crew that does things thoroughly or properly or gives much, if any ishts. They probably just screeded it and left it unfinished for all I know then hosed it.
I watched a crew do this very thing on a new driveway pour for our neighbors. He couldn’t explain exactly how it works but if the cola is just acidic enough it would weaken the cure on the top layer and it’ll wash off easily. Is it really the sugar? Interesting…
The ingredient in Coca-Cola that does this is phosphoric acid. II used to get it at one of the big box stores. Doesn't look like it's available these days.
Phosphoric acid is the main ingredient in many rust remover products. If there's no ingredient info on the label, then Google the product name and "sds" together (or "msds") to find online PDFs of the material safety data sheets. Those sheets often list an active ingredient.
So many questions now. If it's the sugar water that creates the effect, why not just use sugar and water? Does that sugar water weaken the surface everywhere you spray it? If you do a pattern, how long until that pattern disintegrates from normal wear since it is already weakened?
It's a very well studied retardant effect from sugar. Muriatic acid will etch the concrete. Which leaves it much more porous unless you apply a sealant coat. To verify that it's not the phosphoric acid the experiment could be to divide a slab into three equal sized areas. On one add a half liter of water, on the second add a half liter of coca cola, on the third add a half liter of sugar water. Wait two hours or so and power wash evenly and see the results. If desired do a fourth area of diluted muriatic acid. Post the video.
As a tile setter, acid inhibits the reaction (which is how grout haze remover works). I'd worry for that pattern idea even after it set. It would likely have tons of efflorescence and be prone to chipping. I'd love to see a "one month later" video to see how it weathers. Science!
I love love love terrazzo and anything similar to it. Finally I’ve been begging for several years now lol. But no thank you, exposed rock is far more interesting and pretty than plain ugly, smooth concrete
But do you need the coke? You should have done a couple of different blocks. With as much material material you removed in the "retries" I bet you $1 that you negated anything the coke was supposed to do. If you would have mixed the concrete right and used the fan on the pressure washer, I bet it would have been perfect.
I'd protect the side I wanted to keep smoothe from getting Coke on it. The acid will weaken the cure, and rain will eventually make it do the same thing.
You would have the same results without the Coke. Now pour some Coke on the hood of your favorite vehicle, wait four hours, and see if it damages the paint. Spoiler alert. It will.
I was hoping to do the comparison on another block with no Coke to see what the difference would be
I was literally talking to my parents about this 2 days ago and now you post a video. Thank you!
I would love to see you do a series on how to do stairs. How to form them and how to pour them.
Awesome video we have use cola many times on our concrete projects. Usually we use top cast surface retarder.
You don't need Cola to do that. You get the same results just spraying it with a hose.
If a surface retarder isn't used the stone will just wash off. Cola is a great way to keep 1/8 of the surface soft. Great video
Fill in the aggressively pressured wash area with the blue epoxy!
I used a very light mist of sugar water on the entire path of concrete swail i had at my old house. Worked perfectly.
Can't wait to see it.Hope it turns out even better than I think
I'm curious if the exposed aggregate/rough surface like that would hold water, then with freeze/thaw cycles, erode the concrete faster than normal.
I was gonna say, “Just use your water hose”, but then you eventually figured it out. 👍🏼
Yup, this trick’s been around Forever.
Why would you not make two slabs and run them side by side. One with and another without?
Interesting video Michael. Not sure what the Coke is supposed to do but you can get the same results just using plane old H20!
Cool. Ty
Michael builds coca-cola quikrete buff dye would have looked good on paver with a light blue resin over exposed area? 🤔

You can use sulfuric, muriatic or phosphoric acids, probably citric too.
@@frankdesbaux For anyone wondering: muriatic acid is hydrochloric acid.
So many questions now.

Does that sugar water weaken the surface everywhere you spray it? If you do a pattern, how long until that pattern disintegrates from normal wear since it is already weakened?
Sugar water would work, but it's easier to see whether you have the desired even coating when you use something you can see.
It's more likely the phosphoric acid that does it. It's added as a preservative.
Nice! Can't wait to see the final pour! 🧭
The video didn’t seem over when it ended. Thought you would finish it with a successful run.
Keep them videos coming
Just use a hose, use the template to spray the sugar water.
thunbs up for the Pepsi comment - you got a new sub
sugar water repells concrete? Wouldnt it be the acidity (the phosphoric acid in the coke) slowing the setting of the cement?
Hmm, sounds like we need more tests😊
@@neckbone1584 Yea, i was thinking diluted muriatic acid would probaby do the same thing, (maybe)

Isn't it about time you bought a concrete mixer Michael?
Should have done a control.

Nice!
Probably get same result with vinegar water or muriatic acid and water mixed!
Maybe don't use the laser beam nozzle!
Shoot! I thought you were gonna add a mentos!
I’m a Mountain Dew guy 😅 good choice wasting the coke I use coke for cleaning the corrosion off of my battery terminals😅
I'm a Pepsi guy too! XD
You can just use sugar water. Don't use diet coke, though.
You would have the same results without the Coke.
Now pour some Coke on the hood of your favorite vehicle, wait four hours, and see if it damages the paint.
Spoiler alert.
It will.
Thumbnail. Sorry Mike, there is no D in Happens.
😊
Pepsi W
Your thumbnails spells "happens" incorrectly
I have to unsubscribe due to the Pepsi comment. 😆 🤣 Coke for the win.
EXCUSE ME!!! you did waste something IMPORTANT by wasting Coke!!
I agree with you!!! Coke for the win.
