Concrete slush splashed on new floor

[kolky]

Hi all,

When the concrete guys were pouring my foundation and garage floor it looks like they must have been cleaning out something and splashed concrete slush over the stem wall and onto the new floor. It looks pretty bad. It makes it look like paint got splattered on the floor.

I've got the company owner coming out to take a look at it but is there any way to fix this?

Maybe it's the pic but all I'm seeing is normal color variations of a floor as it cures. Maybe a little water got splashed on the surface? Are there actual splashes of mortar on the surface?

There was actual mortar on the surface. A couple of the guys came out and scraped it off but it still left white spots where ever they were. You can see it better in the pic of the stem wall where there are splash marks going over the side and top of it.

Here is a pic before they scraped it off. Ignore the suds in the picture. That was me trying to scrub it off.

I cleaned concrete splatter off my gas meter with a wire brush and a wet rag. Took a little bit, but it got done.

Ya, I thought about using some sandpaper too but that is still going to make that section of garage floor look different that the rest. Not exactly what I want to do on a brand new build and for as much as it cost to put in.

Got it. For what it's worth, the color of the slab will lighten over time and the spots will be much less noticeable.

I'm with LLWillysfan, I can barely see anything. Certainly not anything to start calling the company principal about. Can you imagine the conversation between the two laborers that got sent out to scrape a slab on a build that doesn't even have a building on it yet? You are going right to the top of their favorite customer list.

You should have explained that you were creating a museum exhibit before construction started. If whatever I am seeing in that picture is that big of a deal to you, I think there are probably some compatibility issues between your expectations and the 'normal' baseline of what a property owner expects/accepts in the construction of a garage.

Not being harsh, just trying to tell you to chill out, let the slab cure and see where you are. If you're that **** about your slab I'm sure it will have some sort of floor down so it won't make any difference in the end anyway. When you are the bill payer and you have all the anticipation and a lot of emotion wrapped up in a build, it is way too easy to lose perspective.

If they sawcut the control joints I am about 98% sure that is some slurry that got dripped or leaked out of the wet vac. Very familiar with it being in the cutting and coring business over 30 years. Once the slab cures try some pool acid diluted with water and a scrub brush it may help but this soaks into the pours and is almost impossible to make disappear. It stains CMU even worse.

That is what I thought it looked like as well. Either dripped out of the vac or a bunch of it was dripping from the saw while someone stood there with it for a couple of minutes. Not the neatest job...
