    I have heard that white vinegar before you paint concrete works
    quite well but the vinegar will in time distroy the concrete.

    pencilcar,

    Acids are frequently used to etch the surface of concrete prior to painting. Vinegar, which is a solution of about 4% acetic acid could also be used for this purpose. As to long term damage, the acid itself will eventually reach a neutral state as it reacts with the alkaline concrete, and no longer be able to cause damage.

    what their describing is also used for exposed aggregate, when this type of concrete is used the finisher will go over teh concrete with a light spray of a release agent type of acid which breaks up the very top of the concrete so the aggregate will show when they go back over it with a pressure washer to wash away the "cream" from the top layer

    In the stucco trade Vinegar is used to expose the aggerate after repair to old stucco this method will blend the new and old.
    Also vinegar is used to lower the PH of new stucco.
    Also vinegar is used as a neutralizing afterwash after paint removers are used.
    Also used to clean efflorescence from brick, stucco and limestone.

    The acidic effects (and pH) of the vinegar will quickly be neutralized by the masonry within a few minutes. We wash masrony (usually tile work) with white vinegar all the time. We'll use half a gallon to clean bad grout haze for example. You can hear it fizzing, which stops within a minute of application or so. Plain water washes away any of the now loosened dirt and grout haze.

    Just keep the vinegar out of your eyes and you'll be fine.
