Drywall Dust
 

I'm in the process of building a new house with an attached garage but also a 1600sq. ft. detached garage. I will do epoxy paint on both floors, but at this stage the floors are covered with much drywall dust, and it's b***h to get up. Obviously the floor needs to be perfectly clean before etching, etc. Anyone have a good way to get all that dust cleaned up? (don't suggest blowing it with a leaf blower as that just makes huge dust clouds.)

Any help will be appreciated.

Cheers.
