Back to the original subject of floor sweep compounds. A lot of the dust from a concrete floor comes from the concrete its self. I sealed my shop floor with Dap Water Repellant Sealer that I bought at HomeBoy Depot. It not only sealed the concrete, it made spills easier to clean up. You wll want to clean the floor before sealing it. Use one part Muriatic Acid (swimming pool acid) to Four parts water. Mix it in a bucket, pour it on the floor and spread it around with a pushbroom then rinse with fresh water. Let the floor dry. To apply the sealer, pour it on the floor and spread it around with a soft bristled pushbroom. Rinse the broom with water when yer done so it doesn't become a stiff bristle broom. I bought a five gallon bucket of the sealer, did my 1200 square foot floor twice, two years between coats and I still have two gallons of the stuff left. A little goes a long way. That was ten years ago. There's too much crap on the floor now to move it all out and put another coat on. The last coat is still holding up after ten years. Now the only dust on the floor is from grinding on cars.
