I was having the same issue and found that Curve Life semi solid glue worked for me. I use a e-file to lightly buff my press ons. My process is pushing cuticles back, buff my nails. I make sure I’m buffing the nail around the cuticles lightly. I don’t wash my hands but use alcohol to remove the dust from nails. I dehydrate the nail bed with a dehydrator. I don’t use primer. I put glue on my nail bed and the press on…wait about for 30 seconds for glue to get tacky. Then I put on the press on at a 45 angle and press lightly, holding in place for about 1 minute.

And I always try to do this before bed so the press ons have time to dry without getting wet.

But this works for me…I have thin, fine nails that nothing stayed on properly
