Concrete dusting is an awfully unattractive and unappealing situation that can plague concrete floors, on occasion. While it is not an indicator of failing structural strength or an impaired or compromised structural integrity, concrete dusting can really harm the visual appeal and aesthetic of your concrete floors. This can be especially harmful to a company whose retail store or warehouse is plagued by concrete dusting, as a clean image can be the difference between success and failure.
Concrete is created through a process that involves mixing together water, Portland cement, and some sort of aggregate, such as sand or gravel. Once these materials are mixed together properly, they can be poured and cured to result in the strong, traditional concrete surface that typically comes to mind when we think of concrete. Concrete dusting is, unfortunately, a natural by-product of the concrete mixing process when the curing process has not been properly completed. Curing concrete is incredibly important to its structural integrity: improperly cured concrete will never reach the full potential for its strength, and it will always also have problems.
Concrete dusting is usually a chalky white or gray dust coloring over the natural gray of concrete, leading to an unpleasant visual facade for your concrete. The easiest way to deal with concrete dusting is to cure your concrete properly. Unfortunately, you likely are not actually overseeing the curing process; its even likely that youre living in a home whose concrete has been poured and cured long ago. Fortunately, there is still an easy and cost-effective way to help reduce and remove concrete dusting without repouring and recuring the concrete, which can be incredibly expensive and tiresome.
Concrete sealers are a great option for the homeowner, contractor, or other concrete owner faced with concrete dusting. You can opt to use an epoxy or urethane topcoat over the dust-covered concrete slab, such as the Epoxy 325 or the Urethane 645. These two products are an excellent choice for locking out the dust and preventing any from appearing on the surface. You could also use an acrylic based product such as the Cryli-Tek 5505 or the Cryli-Tek 5500 to stop dusting. You really need to use a coating versus a sealer since the coating will coat the and trap the dust and prevent it from acummulating.
