How to fix vinegar concrete floor damage?

TheMidnightNarwhal · 05-07-2019, 04:03 PM

It seems that my 50% water 50% vinegar mix bottle cracked and it leaked. Went to pickup my detailing supplies and noticed this in the basement under the milk crate the bottles were in. I tried to put some degreaser/cleaner and it seems to have done nothing.

Any way I can at least make it look less worse... like at least remove the milk crate imprints? My dad's gonna kill me

Now that you know vinegar etches concrete, probably time to tape off some witty phrases and send pops a message.

Have you noticed that I look a lot like Uncle Bill?

Well at least we know you’re not posting from your mom’s basement.

You can try the old cover it with a rug, that always works.

You're kinda screwed.

Vinegar/acid eat the surface of the concrete, that is what you have there.

There are patching products that you can use, but if a novice tries to do it, it will likely look worse then when you started.

How big is the entire floor? You can coat the entire floor.

If you choose to do anything with this these are the guys who make the products you need.

Damn ok, I was just looking at something to hide it a bit. The basement is not finished though anyways so when we do there will be floor above.

Just to make sure, it shouldn't get any worse right?

No, a little bit that is already damaged may flake off around the edges that already flaked off, but nothing new.

You could paint the whole floor, tell your dad you were trying to spruce it up for him and keep the dust down.

just sand it. it will use alot of pads but will at least get the black out. And your going to need an orbital to do anything with that......

bimmerfrk · 05-10-2019, 09:31 AM

and if you really good you can do a skim coat of concrete once you put bondo down. Am i speaking english> good luck

andrewmr · 05-10-2019, 09:49 AM

Do you know anyone with a floor buffer? The big ones they use at malls and such?

If not rent one for a few hours. But, a RO sander could work just as well.

Run over it to get the stains off as best you can. It will also remove the damaged and flaking parts.

When it's as clean as you can get it, just move on, it's only a basement and if/when it gets finished you'll never see it.

bimmerfrk · 05-10-2019, 12:29 PM

you dont need the big ones you need a high speed small orbital. Yur need to smooth it out so you can skim it. You need a fast orbital not what the mall uses.

Redo the entire floor, he'll love ya for it!

The vinegar (acid) dissolved the cement at the surface of the concrete leaving the aggregate (sand + gravel).

You can buy small bags of portland cement here at Lowes and probably Home Depot. You don't want to use any pre-made concrete mix with gravel and/or sand because all you need to replace is the cement. Take this cement powder, add a little water to make a paste, dampen the area that needs to be repaired, apply the cement paste to the damaged areas, press into the damaged areas and trowel smooth with a steel trowel.

The new cement vs. old concrete will be visibly different in appearance, but you should be able to get it smooth and sealed with this approach.

Tell your dad what happened. Be honest and upfront about it. Shit happens. Then offer to pay for it and use arkie6's advice above.

I work at a vinegar bottling facility. You should see our parking lot. Our vinegar will eat anything less than 304 stainless.
