Nice work.
Densifier would be a good idea.
It soaks in and stops the dust, and you can't tell the floor has been coated/there is no visible coating.
Interesting, never heard of that stuff. It would take 3 gallons to do my floor (one 6x40 section was hand-troweled, the remainder power-troweled) so that's $500 right there. I don't remember if it's 3500 or 4000 psi concrete but it's plenty strong and smooth as it is. I could buy a gallon and do the area around and under the lift, and see how that works out
