Acid-Free Primer Builder is a liquid that prepares the nail for extensions, both gel and acrylic. Its function is to dehydrate the nail bed, efficiently preparing it for the technical treatment. Thanks to the special formula without methacrylic acid (MAA), the Primer guarantees an excellent result, creating a double-sided and protective layer between the nail and the product (gel or acrylic). Monophasic and self-modelling, this Acid-Free Primer is suitable for both natural nails and extensions with tip or forms.
