How long do press-on nails usually last and how do I get press-on nails to stay on longer? Glue gets you up to 14 days. Adhesive tabs get you up to 7. Either way, prep is what actually determines how long they stay put. Push back your cuticles, buff the shine off your natural nail, and wipe away oils with the prep pad before you apply anything. Press each tip down firmly, then stay away from water for at least an hour.
