PREP NAILS Shape nails, push back cuticles and remove extra cuticles. Key point - File nails surface. Clean nails and ensure your nails are completely dry, clean and oil-free. Just make sure you prep well or it will peel right off. Practice makes perfect!!! WARM TIPS: Poly nail gel cures with nail lamps. We recommend curing with UV lamp for 2-3 minutes, LED lamp for 60-120 seconds. The time needed depends on the thickness of the gel. It is normal for the base coat remain a little sticky after curing. If you want to change the nail art style and remove the nail extension gel, you can file the nail extension gel down and then buffer it.
