Atica: PERFIX Ultrabond (Acid-Free Primer) "Atica PERFIX Ultrabond" is a professional acid-free primer formulated to create a durable, maximum-adhesion bond between the natural nail plate and gel, acrylic, or builder systems. Its gentle formula is specifically designed to prepare the nail surface without causing dryness, sensitivity, or damage, making it the ideal choice for weak, brittle, or problematic nails. By creating a reliable tacky layer, it acts as a "double-sided adhesive," preventing lifting, chipping, and premature product separation for long-lasting, salon-quality results.
