A preparatory coating applied to the natural nail before the application of artificial nail enhancements or nail polish is designed to improve adhesion and longevity of the subsequent coating. This product typically contains acids or polymers that create a slightly rough surface, promoting a stronger bond between the nail plate and the applied product. For example, after proper nail preparation, a thin layer is applied to the natural nail, allowed to air dry, and then followed by the application of acrylic, gel, or polish.
The use of this preparatory coating is vital for preventing lifting, chipping, and premature wear of manicured nails. By creating a more secure connection between the nail and the enhancement, the overall durability of the manicure is significantly increased. This methodology has evolved as nail technology has advanced, from primarily acid-based solutions to formulations incorporating bonding agents that minimize potential damage to the natural nail.
