Discover the difference between a base coat and a top coat. Learn about their roles, how to apply them correctly and why they are essential for a long-lasting gel or semi-permanent nail polish application with LuluNails Belgium, a Belgian brand based in Liège.
What are Top Coat and Base Coat used for? Complete guide
Whether you’re a beginner or an experienced nail technician, understanding the difference between a Base Coat and a Top Coat is essential for achieving a long-lasting, glossy and durable manicure.
These two products are often confused, yet they serve completely different purposes. Without a suitable Base Coat, adhesion may be insufficient. Without a top coat, the colour quickly loses its shine and becomes more prone to scratches.
At LuluNails Belgium, a Belgian brand, wholesaler of professional products and training centre in Liège, we offer professional base coats and top coats designed to provide excellent adhesion, a flawless finish and long-lasting wear.
What is a Base Coat?
The Base Coat is the first coat applied after preparing the nail.
It creates a bond between the natural nail and the nail-building product or semi-permanent polish.
Its main role is to improve adhesion and minimise the risk of peeling.
The main functions of the Base Coat

A professional Base Coat helps to:
- improve adhesion;
- protect the natural nail;
- reduce lifting;
- promote better hold;
- create a smooth surface;
- optimise colour application.
A good base coat forms the foundation of a long-lasting manicure.
What is a top coat?

The Top Coat is the final layer applied during installation.
It protects the colour or builder gel from scratches, knocks and everyday wear and tear.
Depending on the finish chosen, it provides a glossy or matt effect.
The functions of the Top Coat
The Top Coat helps to:
- protect the colour;
- maintain shine;
- minimise scratches;
- improve durability;
- make cleaning easier;
- extend the life of the manicure.
It’s the essential finishing touch for a professional result.
What is the difference between a base coat and a top coat?
| Base Coat | Top Coat |
|---|---|
| First coat | Final coat |
| Promotes adhesion | Protects the application |
| Prepares the nail | Protects the colour |
| Prevents chipping | Scratch-resistant |
| Invisible under the colour | Glossy or matt finish |
These two products are complementary and cannot be substituted for one another.
When should you apply the Base Coat?
The Base Coat should be applied:
- after preparing the nail;
- after the Nail Prep and Primer, if necessary;
- before applying semi-permanent polish, Builder Gel or construction gel.
A thin layer is usually sufficient to ensure good adhesion.
When should the top coat be applied?
The top coat is applied:
- after the colour;
- after a Baby Boomer;
- after nail art;
- after a top coat.
It is the final step before the final curing.
Can a top coat be used as a base coat?
No.
Although their textures may seem similar, their formulations are different.
Base Coat is designed to adhere to the natural nail, whilst Top Coat is formulated to protect the surface of the manicure.
Using them thewrong way round may result in poor adhesion or the polish peeling off.
Can the application be carried out without a Base Coat?
In most professional procedures, the Base Coat is strongly recommended.
It improves adhesion and helps ensure the longevity of the application.
Can you apply nail polish without a top coat?
A manicure without a top coat remains much more vulnerable:
- to scratches;
- loss of shine;
- everyday wear and tear.
Top Coat is essential for providing long-lasting protection for your work.
Glossy Top Coat or Matt Top Coat?
Glossy Top Coat
The glossy top coat is the most commonly used.
It provides:
- intense shine;
- a mirror-like effect;
- an elegant finish;
- long-lasting protection.
Matt Top Coat
The Matt Top Coat offers:
- a velvety finish;
- a modern look;
- a very on-trend look;
- an original touch.
The choice depends on the style you’re going for.
The most common mistakes
To ensure a long-lasting application, avoid:
- inadequate preparation of the nail;
- applying a layer of Base Coat that is too thick;
- inadequate curing;
- failure to apply the Top Coat;
- paint spilling over onto the cuticles.
These mistakes can reduce the longevity of your manicure.
