Adhesion Base
Adhesion Base
An adhesion base is applied in a thin layer between the prepared natural nail and the next product. Its purpose is to improve the anchoring of gel polish, gel or acrygel, but it does not create structure and does not replace a builder base.
What is an adhesion base used for?
An adhesion base creates the first connection between the natural nail plate and the professional treatment. Base Step One 15 ml is intended as the first layer before gel polish, gel and acrygel when you want to support even adhesion throughout the system.
It should be applied in a small amount: its role is not to reinforce or shape the nail, but to prepare the surface for the next product.
When to use Base Step One
- Before a gel polish base.
- Before a builder gel or gel overlay.
- Before applying acrygel.
- When the technical protocol requires a first thin adhesion layer.
How to apply an adhesion base
- Complete the manicure and prepare the natural nail plate correctly.
- Remove dust and residue without touching the nail again with your fingers.
- Use any nail prep products selected according to the type of nail plate.
- Apply Base Step One in a thin, even layer, avoiding the skin and cuticles.
- Cure according to the product's specific instructions.
- Continue with the base, gel or acrygel required for the treatment.
For more detail, see our guide to the function and application of Base Step One.
Adhesion base and builder base: what is the difference?
An adhesion base is used as a first thin layer and is designed to promote anchoring. A builder or reinforcing base, on the other hand, can create thickness, correct the surface and build a small structure. The two products therefore perform different functions and can be used in sequence.
Mistakes to avoid
- Applying a layer that is too thick.
- Using it to create an apex or structure.
- Applying it to an unprepared nail plate or one with dust residue.
- Allowing the product to touch the skin or cuticles.
- Confusing it with Nail Prep, Bonder or Primer.
Adhesion base FAQ
Does an adhesion base replace Nail Prep or Bonder?
No. Nail Prep, Bonder and an adhesion base perform different functions. The choice of prep products depends on the type of nail and the professional protocol being used.
Can Base Step One be used with gel polish?
Yes. It can be used as the first layer before the gel polish base, following the product protocol and instructions.
Can it also be used with gel and acrygel?
Yes. Base Step One is designed to promote adhesion before gel and acrygel as well.
Does an adhesion base create structure?
No. It should be applied in a thin layer. For reinforcement, an apex or surface correction, a structural base or builder gel must be applied afterwards.
