Step 1: Apply DUPLEX UV-BASE COAT quickly in even brush strokes from the middle of the nail bed to the nail tip. The nail polish brush made of particularly fine nylon fibers is slightly flattened and oval towards the tip, making it easier to apply it precisely, even on the edges of the nail. Step 2: Harden the base coat in the POWER LED LIGHT for 60 seconds immediately after application. Adjust the curing time accordingly for devices with a low wattage. Make sure that all nails are evenly irradiated by the UV light. Step 3: Apply a very thin coat of DUPLEX UV NAIL POLISH in even brush strokes. Step 4: Sheath nail syringes. If nail polish gets on your skin, remove the color with a manicure stick before it hardens.
