8. Apply the top coat

You’ll only have about 2 hours to work with the mixture. Using a clean paintbrush, cut in at corners, edges, and seams. Then, using a 3/8-inch-nap roller, start at a point farthest from the exit and roll on the clear coat in 10-by-10-foot sections as you did with the epoxy paint. Work first in one direction, then in the perpendicular direction on each section, making your way forward until the entire floor is covered. The coating will appear white or milky at first but will dry clear. Allow 24 hours drying time for foot traffic and up to 72 hours before parking a car—longer in humid or cold weather.
