How to use G Pen Extra Base Gel Polish:
Prepare the nails, buff the surface, push back the cuticles, and degrease the surface.
Treat the surface with Primer.
Apply a thin layer of G Pen Extra Base and cure for 30 seconds. Avoid curing longer, as the adhesion strength of the material will decrease.
The next step can be base, gel, polygel, or even gel polish directly.
Paint the nails with the chosen gel polish color in a maximum of 2 layers, curing each layer with a UV lamp.
