A base coat is the foundation of every gel manicure. Most retention problems start here, so it is worth choosing deliberately.
What acid primers do
Acid primers lightly etch the nail plate and help gel bond to oily or problem nails. They work well, but they are strong: use a tiny amount, keep them off the skin and never use them on thin or damaged nails.
When acid-free is enough
An acid-free primer (bonder) works like double-sided tape between the natural nail and the base. For most clients with healthy nails it gives excellent retention without the risk of over-etching.
A quick rule of thumb
- Healthy, normal nails: acid-free bonder + rubber or strong base.
- Very oily nails or repeated lifting: acid primer on the free edge only, then the base.
- Thin, sensitive or damaged nails: acid-free only, and a flexible base.
Whatever you choose, prep is what makes the difference: push back and clean the cuticle, remove shine and dehydrate before priming.
