Is Pro-bond part of the Gelish range and recommended? I think it is a Harmony product for their acrylic. It certainly wasn't part of my Gelish training. I think if you use it on the whole nail plate under Gelish you will have problems with removal. I only use PH bond and have never had peeling. I assume peeling could be caused by oils etc. still on the nail plate. Do you do dry prep?
PH Bond is used after prep, it is a dehydrator and also removes oils from the nail plate prior to application of all Harmony systems.
Pro-Bond is an acid free primer used after Ph Bond for Gelish Hard Gel & Fusion Acrylics. It is not for use with Gelish Soak Off gel polish.
Can you talk me through your prep routine and application to see where I can help? You may find going on a 1 day training course will help you too x
