Liquid, colourless gel for the base coat. This is the first layer in the 3-phase gel system, but it is not mandatory. It provides an extremely robust adhesion of the gel to the nail plate. Particularly suitable for use, if the natural nail is fragile, sensitive, breaking, splitting, etc. Apply one even, solid/rich, but not thick layer on the nail plate, cure for: 60s under a LED lamp or 2min under a UV lamp.
