While polyaspartic and epoxy coatings are very similar in durability, longevity, and protective benefits, they are vastly different in their curing time. Polyaspartic coatings take about one day to install and 24 hours to be 100% cured. Epoxy floors can take multiple days of installation and up to 4 days to fully cure, depending on whether you are simply walking on it, parking a vehicle on it, or installing something heavy and permanent on it.
