What We Do Only for professionals. Perform standard nail prep, before applying your chosen prep treatment. For adhesion, we recommend applying a primer. Then in a thin, even coat, apply your chosen base. Cure before applying one coat of your chosen color, and cure again. Apply another coat until desired opacity is achieved, ensuring you cure in-between coats. Once you have finished applying color, apply one coat of top. Wipe the sticky layer off all nails with a conditioning cleanser.
