Gel Primer is the grip layer between the natural nail and everything you put on top of it.
It is the step people skip when they are in a hurry, and it is usually the reason a set lifts at the cuticle three days later.
What it actually does
pH Bonder takes the oil and moisture off the plate. Primer is the next step: it gives the base coat or the Extend Gel something to hold onto. Skip it and you are relying on the base coat alone to bond to a smooth, slightly oily surface — which is where lifting starts.
Where it sits in the system
- Cuticle pushed back, plate lightly buffed
- pH Bonder — dehydrates
- Gel Primer — grips
- Base Coat, or Extend Gel if you are applying tips
- Colour, then Top Coat
Applying it
- Thin. One thin coat is all it needs. A thick one takes longer to flash off and can pool at the sidewalls.
- Off the skin. Keep it on the plate — primer on the surrounding skin is a common cause of irritation and it does nothing useful there.
- Let it flash. Give it a moment to go matte before the next layer. Most primers are air-dry, not cured.
- Re-prep if you pause. If the nail has been sitting or has been touched, wipe and re-prime.
Two sizes
The 15ml bottle suits a home kit or a tech working through a normal week. The 250ml salon size is the same primer in bulk — worth it once you are getting through bottles rather than buying one at a time.
