Concrete dusting is a direct result of surface deterioration caused by surface abrasion. New concrete, old concrete, and weak concrete will often experience dusting, or white powder, on the surface. This is common in new concrete as the concrete is curing, old concrete that has weakened with age, and concrete surface that experience high amounts of traffic or surface abrasion. Concrete dusting can be reduced, and in many cases even stopped. The severity of the dusting will determine the best solution.

The most common solution for concrete dusting is to apply a penetrating concrete sealer. Under this category there are two types of sealers, Hardeners and Densifiers, and Water Repellent Sealers. Hardeners and Densifiers, like the Armor S2000 and Armor L3000, are designed to chemically react below the surface to form a permanent Calcium Silicate Hydrate (CSH) barrier within the pores. Once fully cured, the CSH barrier will provide the surface with an increased strength of up to 45%. Densifiers can be used alone or in combination with a Water Repellent sealer. Water repellent sealers, like the Armor SC25 or Armor SX5000 help to prevent further deterioration caused by water absorption by forming a hydrophobic barrier within the pores. This type of sealer is often used to help protect the surface after being sealed with a Hardener and Densifier.

When a sealer isn't enough, a coating may be required. Coatings are designed to leave a visible surface film. It will protect the surface of the concrete and prevent any more deterioration caused by surface abrasion. Popular coatings include Acrylic Sealers, Epoxy Coatings, and Urethane Coatings.
