I'm looking to sort out the concrete floor in the garage, which is dusty but otherwise clean. A sealer of some kind would do in the first instance; anything that will allow me to brush or wipe the surface clean. There seem to be hundreds of options out there (example), so looking for some guidance. I've had a look at a few floor paints, but it sounds like these do not adhere well to bare dusty surfaces, even when brushed and vacuumed beforehand. An epoxy product might do the trick, mind.
