I don’t get how sealing the concrete keeps down dust. But doing anything to the floor that makes it smoother, like painting or an epoxy coating, will make it easier to sweep.

I’m not sure if you were complaining about the cost or not, but $50/gal seems pretty cheap to me. A gallon of high quality house paint can push $70.

Lot’s of options, but painting is likely the least expensive thing you can do.

I did a quick search on concrete sealers and Lowes has something called “Seal-Krete” for $32/gal. Covers up to 300 sq ft. It is clear and ready for a car in 72 hrs (3 days).

Just about anything that you expected to stick or penetrate will require preparation (cleaning and etching). A typical garage floor has oils in it.

I remember doing my parents garage 40 years ago. New house with clean slab, we used muriatic acid to etch it and painted it with some type of DIY epoxy paint. It has held up fine after 40 years of light use (I.E., garage usually had to much crap in it to fit a car in).

By the way, what does “Slab is prepped with vinyl sheets.” mean?
