Prepare the nails for initial application of enhancement products. Use your file and cleanser to gently remove shine, oil, and contaminants from the nails. This ensures a clean as possible surface for maximum adhesion.
Apply 2 coats of protein bond to each nail for hard gel and acrylic. For gel polish, only a small amount of protein bond is needed on the very edge of each nail.
For nail polish, 1 to 2 coats of protein bond (depending on how oily the nail beds are) can protect the polish from chipping for a week.
