The choice between acid primer and non-acid primer depends on the client’s nail type, condition, and any lifting issues. Here’s a breakdown:
Use Acid Primer When:
- The client has very oily nail beds.
- There is a history of product lifting, especially with acrylics or hard gels.
- You’re working on a client with no known sensitivities or allergies.
- The nails need maximum adhesion—e.g., in high-performance or long-wear acrylic sets.
Note: Acid primer contains methacrylic acid, which creates a strong bond by etching the nail plate. It’s effective but can be harsh and cause damage if overused.
Use Non-Acid Primer When:
- The client has normal to dry nails.
- You’re working with soak-off gels, builder gels, or BIAB.
- The client has sensitive skin or allergies.
- You want a gentler option that still provides good adhesion without the risk of over-etching or irritation.
Non-acid primers are generally safer and more modern but may not perform as well in extreme lifting cases.
