Approximately 3-5 days. The typical Seamless Flake Epoxy Floor System is made for long term durability, which requires several coatings to be applied to achieve. These coatings require curing time to dry between each coat. ^-12 Hours for most coatings. There are now coatings called Polyaspartic which can dry much quicker, allowing a floor system to be applied in only one day. Polyaspartic resins offer many benefits over traditional resins, higher abrasion resistance, chemical resistance, faster installation, and better overall performance.
