Lourian French Rubber Base Gel VS Hard Builder Gel: Which One Is Right for You?

We have 2 Hot products: the French Rubber Base Coat and the Hard Builder Gel. But We totally understand it can be confusing to figure out which one is the better fit for you. Both help you create beautiful, strong nails, but they do it in different ways. Think of them as specialized tools in your nail kit—each playing a distinct role.

Let’s break down the differences in a simple, easy-to-understand way to help you make the best choice.

Key Difference: It’s All About Function

At its core, the French Rubber Base Coat is a Base Coat that can also perform light extensions. The French Rubber Base Coat create a substantial, protective layer on the natural nail. This layer acts as a shield, protecting the nail from external damage while also providing a smooth, even surface for the application of color. This is a crucial feature for individuals with soft, thin, or flexible nails.

On the other hand, the Hard Builder Gel is an expert when it comes to building and extending nails. The Hard Builder Gel is specifically formulated to build and sculpt the nail, making it an ideal choice for those who want to create dramatic extensions or repair damaged nails. It can create a strong, stable foundation for nail extensions and add significant length and shape to the natural nail. It is also an excellent choice for repairing broken or damaged nails, providing added strength and support.

This fundamental difference influences every step.

Let’s Dive into the Details:

1. Function & How to Use

French Rubber Base Coat: This is your all-in-one solution for strong nails. After prep work (like callus treatment and nail buffing), you can directly use it with Cartine unghie to create short extensions. Once cured under the LED/UV lamp, then simply file your nails type. The best part is that it works as both a base coat and a builder gel in one step!

Hard Builder Gel: This requires a two-step process. First, After prep work you must apply and cure a base coat. Then, use the Hard Builder Gel with nail tips or Cartine unghie to create extensions. Cure again, then make the nails filing. It’s a dedicated building product.

2. Color & Appearance

French Rubber Base Coat: We offer up to 104 colors! This means you can get a pretty, opaque nude or colored base in one step—saving you time and effort. It’s perfect for achieving a ‘my nails but better’ look.

Hard Builder Gel: We have 20 colors. It focuses more on structure than full color coverage, though some colors do not have the same coverage strength as the French Rubber Base Coat.

3. Texture & Feel

French Rubber Base Coat: It has a thick consistency and adheres tightly to the natural nail. It’s dense yet highly flexible. We like to think of it as a strong, flexible ‘foundation’ that protects thin, soft, or bendy nails.

Hard Builder Gel: This formula is thinner and offers excellent self-leveling—it spreads evenly, doesn’t flood the cuticles, and creates a perfectly smooth surface. Once cured, it’s harder and more durable than the Rubber Base Coat, providing a solid, sturdy structure.

4. Performance & Smell

French Rubber Base Coat: Designed for shorter extensions and amazing adhesion. It’s the champion of nail reinforcement. One thing to note: it has a strong, typical gel odor.

Hard Builder Gel: This is your go-to for long, dramatic extensions. Of course, it can extend your nails to any length you need, or keep them at a medium length—it's quite professional. It creates incredibly strong and long-lasting nails. A big advantage for many users is that it’s odorless!

So, Which One is your Perfect Match?

Choose the French Rubber Base Coat if:

l Your nails are naturally thin, soft, or bendy and prone to breaking.

l You want strong reinforcement rather than extreme length.

l You prefer a simpler process (base and builder in one step!).

l You love having a wide range of nude or colored base options.

l Your main need is natural-looking, strong, flexible nails with a bit of extra length.

The French Rubber Base Coat is your must-have buddy for healthy, protected, and beautifully strengthened natural nails with a touch of added length!

Choose the Hard Builder Gel if:

 The Hard Builder Gel is your perfect choice for creating long, eye-catching, super-strong, and durable nail extensions!

These two products are designed for different needs and preferences. There’s no ‘better’ product—only the one that’s better suited to your manicure needs.
