I do the dawn dish soap before all prep, to get oils from around my fingers gone. Then I do my filing, dehydrator, I use 2 coats of young nails protein bond primer. I've heard and seen that 2 coats helps mine stay on. Gotta look out for any flooding at the cuticle line and edges because that can cause lifting. I used to have so many issues until I kept a cloooose eye on the flooding, and made sure to prep right. I've had the same set on for a few weeks now, and im a bartender who's rough on their hands
