F.O.X Ultrabond non-acid primer, 14 ml
F.O.X Non-Acid Ultrabond is a gentle, acid-free primer that creates a strong foundation for any nail enhancement system — gel polish, builder gel, acrygel, or bio-gel. It’s the first step in your application process, promoting excellent adhesion between the natural nail and artificial material.
Formulated with minimal methacrylic acid, it’s safe for thin, sensitive, or problem-prone nails. It doesn’t alter the pH of the nail plate, won’t cause burning or irritation, and doesn’t damage the nail’s structure.
No UV lamp needed — just apply and let it air-dry for a few seconds before moving to your base coat.
Why nail techs love it:
- Strong, reliable adhesion without acid
- Safe for thin, splitting, or sensitive nails
- Doesn’t penetrate or damage the natural nail
- Helps prevent lifting and speeds up prep time
- Great for problem clients who struggle with retention
A must-have for clean, secure prep — especially when working with delicate nails.

This stuff is so good! I’ve had some of my best retention outcomes with this primer. Even more so when paired with the rubber based coat. Highly recommend!
