What does primer allow a nail surface to bond with?

The correct choice is related to the function of primer in nail care and enhancement processes. Primer is primarily used to prepare the nail surface for the application of acrylic materials. When acrylic products are applied, they must adhere securely to the natural nail; primer helps achieve this strong bond. It works by creating a slightly rough surface on the nail, which increases the surface area for the acrylic to adhere to, thus enhancing durability and reducing the risk of lifting.

In contrast, while gel materials can also use priming agents, they typically require different types of primers or none at all in some cases. Polish and foil do not require bonding agents in the same way that acrylic does, as polish is applied directly to the nail surface or a base coat and foil is primarily used for decorative purposes rather than bonding enhancements.
