Harmony Gelish-  Pro Bond Acid Free Nail Primer - .5oz/15ml

ProBond is an acid-free primer with a neutral pH; it’s also a keratin bonding agent, joining two surfaces together for complete adhesion.

How to use ProBond:
- After the natural nail has been properly prepared and cleansed using the Nail Surface Cleanse and a Wipe It Off lint free nail wipe, apply 1 coat of pH Bond to the nail plate. Apply 1 thin coat of ProBond and allow it to dry. It will remain shiny.
With proper preparation and ProBond, PolyGEL™ is virtually lift-free.
