Before diving into a whirlwind of color, there is one simple yet essential step you should never skip: base coat nail polish. The true foundation of every manicure, it protects your nails, strengthens them and helps your nail polish last longer. But which one should you choose? What is it used for? And why is it such an essential part of your routine? Here is everything you need to know for a flawless manicure and beautifully healthy nails.
Key Points:
- The base coat is the first layer of a manicure, applied to bare nails before the color.
- It evens out the surface, protects the nail, and helps the polish last longer.
- It prevents color pigments from settling directly on the nail plate.
- It is always applied before the polish—not to be confused with the top coat, which is applied last.
- The Manucurist rule: 1 coat of base coat, 2 thin coats of polish, 1 coat of top coat.
A base is the foundation
A base coat nail polish is the essential first step to a successful manicure. Applied to bare nails before your color, it is usually transparent. Just like a makeup primer, a base coat creates an even surface and prepares the nail for color application. But its role goes far beyond simply smoothing the nail. It does so much more than that.
Protection, adhesion and longer lasting color
Applied before your nail polish, a base coat nail polish creates a smooth, even surface that helps your color grip the nail more effectively for improved wear. It also acts as a protective layer between your nail and colored polish, shielding your nails from staining pigments and from external factors, such as moisture, that can weaken them.

A base coat nail polish is step one for a flawless manicure that lasts.
Before or after your nail polish?
At Manucurist, both the Green™ and Green Flash™ manicure routines follow one simple rule: the four coat routine.
- 1 coat of base coat
- 2 thin coats of color
- 1 coat of top coat to seal in the color and extend wear
⚠️ Do not confuse a base coat with a top coat.
While a top coat is applied last to add shine and create the perfect finish, a base coat is always the very first layer before applying color. It creates a smooth surface for the best possible nail polish application. Another benefit is that it prevents pigments from bonding directly with the nail plate, making color removal quick and easy with a gentle acetone free nail polish remover.
Which base coat goes with which nail polish?
First of all, it is important to remember that you should always use products from the same range, as each formula has been designed to work perfectly together.
The right base coat depends on the type of nail polish you choose.
