How to Prevent Concrete Dusting

Concrete dusting is a nuisance for the visual appearance of your concrete. While it will not harm the structural integrity of your foundations, basements, or other concrete surfaces, concrete dusting can require a lot of cleaning while making everything look dingy and uncared for.

Concrete dusting is usually due to poorly cured concrete. Concrete gains much of its famous strength through a process known as concrete curing. After the aggregate, water, and Portland cement are mixed together, the new concrete sets and must be kept at a certain level of temperature and moisture in order for it to cure properly. Without a consistent temperature and moisture level, the concrete will not cure to the full potential of its strength. Poorly cured concrete can also lead to undesirable conditions like concrete dusting.

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.

Concrete sealers are a great option for the homeowner, contractor, or other concrete owner faced with concrete dusting. The best product to use is more of a coating than a sealer since a concrete coating will be able to lock in the dust and completely stop the concrete from dusting altogether. If you are looking for an extremely durable option you could use the Epoxy 325 primer followed by the Urethane 645 top coat. Before using the epoxy and urethane we do recommend acid etching the concrete or mechanically scarifying the concrete prior to applying the coatings. If you are looking for a product that requires less surface preparation, The Cryli-Tek 5505 and Cryli-Tek 5500 products can also be used although they will need to be reapplied more frequently.
