On this client I used regular polish over gel overlay, my prep I do believe is good I push back cuticles n scrape pterygium,then I buff shine off nail with a 180 grit file, I brush off dust then rub fairly hard with prep, I also used opi bond aid dehydrator because she has issues with this gel chipping, I then use balance bond primer, I put thin coat of builder gel on n really work it in cure for 2 min, then I put another layer of builder on n build the nail her nails r really short so there ain't much apex to build, I cure for 2 mins cleanse nail with alcohol file if needed, this time I used glaze n go before I used regular polish because I figured I needed to seal the gel, because last time I didn't n they chipped to. But 4 days later she sent me these pics of her nails that chipped at her free edge.both corners of her nails.n that was the case the last two times I did her nails. I use balance builder on myself n two other clients overlays on natural nail I even built a free edge on a client n its still good I just do fills on her. So I don't understand, being new to this industry its really frustrating as to why does this happen to her n not me or the other two. N thank u for redponding
