Concrete dusting can be caused from a variety of factors including poorly mixed concrete, surface abrasion, age, water or moisture, and a variety of other factors. Regardless of the cause, the solutions are fairly similar. The most common way to reduce concrete dusting is with the use of a sealer. Sealers are easy to apply, cost effective, and won't change the look, color, or surface characteristics of the concrete. Depending on the severity of the dusting, more than one sealer may be required. The first sealer you want to put down is a Sodium or Lithium Silicate Densifier, like the Armor S2000 or Armor L3000. Densifiers penetrate into the concrete where they chemically react to form a permanent CSH (crystalline structure) within the pores. After a few treatments, concrete will receive an increased strength of up to 45%. After the sealer has been cured wait a week and clean the concrete. Do not clean the concrete before that point because Densifiers may push dust to the surface while it is curing. You will be able to tell at that point if the concrete needs another treatment. Once you have finished your Densifier treatment you can leave the concrete alone, or apply a water repellent sealer, like the Armor SC25 or Armor SX5000. These sealers will not only help to reduce dusting, but they will protect the concrete from deterioration caused by water and moisture.

If you have dusting issue that can't be solved with a sealer, or if you don't have the time to apply multiple treatments, consider a coating. A coating will leave a visible surface on the concrete. It penetrates into the pores in order to bond and will coat the concrete with a protective layer. The coating will stop concrete dusting by stopping abrasion to the surface. Coatings can be acrylic, like the Armor AR350 or Armor AR500, epoxy, or Urethane, like the Armor UTN60. Which coating you use depends on what the floor is used for. Acrylic sealers are great for most applications but in areas which heavy abrasion or high traffic, a urethane may be required.
