How do you fix an epoxy floor?
Apply another coating of epoxy. Once you sand away all the bubbles and clean up any dust, you can easily recoat your epoxy. Touch up small repair areas, or recoat your entire floor, depending on how much of your floor had bubbles. Use a 3⁄4 in (1. 9 cm) wide roller, and pour your well-mixed epoxy into a paint tray.
