    yes! sweeping compound. sometimes you can get it in 50 lb bags but as a building custodian we've always ordered it in 55 gallon drums. these days, its usually green-colored and push it best with a 'drag-mop'

    That's one of the few useful things I learned as a boy scout: how to sweep a large room.
    At first, I thought spreading the green stuff all around the floor
    was an honesty test: to assure I really swept the entire floor.
    But then I saw how all the dust was clumped with just a broom.

    I vounteer at a museum with large old buildings.
    We've used several 50 lb bags sweeping out the dust-of-ages :-)

    It won't work in my basement/shop. The concrete is dusting. The more
    I sweep, the more there is to sweep. :-(

    I have heard that for problems like dusting, acid washing the floor,
    and then sealing it with epoxy or a good floor paint will solve the problem.

    The dust is bad for a vacuum cleaner, even; it jams the brushes.

    Yeah, you need to clear out of an area, apply floor paint, then stay away until the aroma subsides.
    Or, put down vinyl. That requires moving most of the equipment and furnishings.

    Best done in summer, with lots of ventilation. It really helped my basement and stairwell,
    which had been perpetually damp. A washdown ahead of time, with floor squeegees to push
    the dirty water to a drain, is strangely satisfying. Pressure washer recommended.

    SWMBO wouldn't appreciate the stink. I'd have to have some mighty fans
    to clear the ail.

    I guess I could do one room at a time. I could move everything into

    Or do every thing at once and the take the SWMBO on a nice week end to
    the mountains.

    The smell may be less that you thing, as the resulting salt is odor
    less, Probably use a solution of HCL and the salt would be CaCl2

    As you do the washing you will definitely need very good ventilation or
    a or a Scott Air Pac like are used in Fire rescue.

    I wonder if there is somewhere to rent such a thing? Or hire out the
    job? There have to be people who do garage floors.

    I'm also worried about the animals upstairs. I could lock them on the
    second floor and open all the windows.

    Having used Muriatic Acid (HCl) for a swimming pool, I wouldn't discount
    the smell. Every once in a while the smell would come up and get you--even
    if using mostly safe techniques. (Open the bottle at arm's length, add
    acid to water not water to acid, no hugging the bottle, don't drink it,
    etc.)

    There is a latex based floor sealant that's not too bad. It dries clear
    but shiny (like most white glues or Matte Mediums do). It does seem to
    keep the dusting down. My layer of sealant is quite new, so it's hard to
    say if it'll last as long as acid washing the concrete and epoxying it.

    If you forget acid to water, not water to acid. Think of it
    differently. Always put the heavier ( most dense) liquid into the
    lesser dense liguid.

    If it is not required because of the heat released on mixing (water to
    acid), it also helps with the mixing, as the dense liguid sinks into the
    less dense liquid and mixes as it sinks.

    "There he lies, cold and placid, because he added water to the acid."

    It's more than that. If a violent reaction occurs it's better to
    splash water than acid.

    Adding acid to the water starts out with a lower concentration of
    acid. Adding water to the acid starts with a high acid concentration.

    Not always possible. Topping off a lead acid battery. I understand,
    better the other way.
