Dried Cement on Paint

[brondondolon]

Lol I would never think sugar could remove cement. Please post pics after u give the sugar a try. I'm very interested in this.

I'll get to it in a couple of weeks but I will post when done. I thought the same thing myself when I first read the sugar-water trick. Lol.

This thread apparently is not only a lesson on how to remove dried cement from your paint, but a lesson on how to handle groceries in the garage on a rainy day...

I'll be interested to hear if this works....


For those reading this into the future, like Bob mentioned, Back-Set is a product made just for this type of problem.

One of my students, been through my Detailing Boot Camp Class posted this thread with his experience and before and after pictures.

How To Remove Concrete Overspray off car paint

[FrankS]

I work for a company which does a lot of concrete testing on construction projects and also in the laboratory to determine the compressive strength of concrete samples. It is known in the concrete industry that adding sugar to a concrete mix can retard the hardening process (or hydration process) of concrete. In other words, by adding sugar to a mix of concrete, the concrete will take longer to harden or set.

Im almost tempted to splatter some concrete on my truck and test this sugar method out my self. Im too impatient and want to know now lol

Although I agree that sugar can screw up a batch of concrete faster than anything (one of my good friend is the largest concrete contractor in South Louisiana), I strongly suspect that the effect Frank described would apply mostly to the "uncured" concrete, rather than the set and cured product.

I live in sugarcane country and have had sugar in all form (from raw to refined) on the concrete of my shop, mixed with all kinds of chemicals (acidic and alkaline) and I haven't seen any dissolving of my concrete. I am not saying it does not have any effects, but would question the chemistry a little. Acetic acid (vinegar) does had a pH of 2.4, so who knows!?!?

Subscribing to see if we have found the million dollar idea.... or the next best salad dressing (since those two are the primary ingredients)

When cements, including any of their admixtures, cure/dry/set-up...Do they not become concrete?

With that in mind:
I can see where: Sugar(s)...will retard cements' setting-up processes...even, IMO: sometimes indefinitely. (Probably by preventing the formation of some silicate hydrate of calcium or another.)


So...It would be interesting to know:
How sugar(s) would work to reverse those processes of what it takes to have a:
Now already, has been set-up/"dried"/cured concrete.

Bob, Bob, Bob...cement is merely an ingredient in concrete.

...cement is merely an ingredient in concrete.

This is true. There is a difference between concrete and cement. Concrete normally consist of cement, coarse aggregates (or rocks), fine aggregates (or sand) and water. Cement is like the glue that holds them all together.

I was referring that sugar can be a retardant to "wet" or unhardened concrete though.
