Cutting concrete with a power saw produces enormous amounts of dust. When the dust becomes airborne, it's possible to inhale it into your lungs, which can create severe health problems. While you can find vacuum systems designed to collect the dust material, the systems aren't fully effective. Applying water to the cutting blade or concrete surface using either a garden hose or plastic bucket appears to be the best method for controlling the dust produced by the blade.
Things You'll Need
- Garden hose
- Spray nozzle
- 5-gallon plastic bucket
Video of the Day
Attach the garden hose to a nearby outdoor water spigot. Connect the spray nozzle to the garden hose. Turn the water on.
Wet down the area before starting the cut. The surrounding wet surface aids in collecting the dust.
Adjust the outdoor spigot valve so it emits a small, steady stream of water from the spray nozzle when you fully depress the handle.
Employ a helper to operate the spray nozzle. Direct the stream of water at the blade when cutting the concrete.
Make a small hole, 1/8-inch in diameter, in the bottom side of the 5-gallon plastic bucket.
Fill the bucket with water.
Set the bucket next to the cutting line. Orient the hole so water weeps onto the cutting area.
Move the bucket as needed to keep the water concentrated over the appropriate section of concrete cutting.
