Ultra bond is a professional non-acid primer. It’s used to ensure maximum adhesion of the artificial material to the natural nail plate. The balanced acid-free formula maintains natural balance and doesn’t penetrate into the lower layers of the nail plate. The coating dries in air in 1 minute.
Expert’s advice: before applying Ultra Bond use Dry Bond conditioner that gently removes excess moisture from the surface of the natural nail plate and degreases it. This gives an additional guarantee of good adhesion of the coating which is important when working with "problem" nails.
