A non-acid based primer leaving a tacky surface to aid even the most troublesome nails. Apply a thin layer to the natural nail during a full set or fill. Let set 60 seconds, it will not look dry like a standard primer. Works completely different than a standard MAP Primer (like No Lift) - for maximum adhesion, use after you apply No Lift Primer. Tip: Have a stubborn fill line? Affixit serves as a Line Out to fill in and mask small lines.
