Find the Right Builder Gel for Your Technique

Not all builder gels work the same way.

Some formulas flow smoothly across the nail, while others hold their shape for more controlled construction. Hardness, flexibility, colour coverage and application method can also vary.

Explore our specialist collections:

  • Self Leveling Builder Gels for smooth, controlled application
  • Jelly & Non-Leveling Gels for precise shaping and greater stability
  • No File Builder Gels for techniques designed to minimise finishing work
  • Coloured Builder Gels in nude, pink, milky and decorative shades
  • French & White Builder Gels for classic French and Baby Boomer designs

Whether you're creating a natural-looking overlay or extending nails on forms, choosing the right formula helps you work with greater control.

Self Leveling Builder Gels

Self leveling builder gels are designed to smooth themselves across the nail surface during application.

They help technicians create balanced nail structure and an even finish, potentially reducing the amount of filing needed after curing.

Explore systems including Excellent Pro Hard Liquid Gel, Saute Nails Easy Leveling PRO and selected Yoshi builder gels for professional overlays, extensions and refills.

Different formulas level at different speeds, so choose according to your preferred working technique.

Jelly & Thixotropic Builder Gels

For greater control during nail construction, discover jelly and thixotropic builder gels.

Jelly builder gels typically have a thick, stable consistency that helps the product maintain its position during shaping.

Thixotropic gels behave differently. Often described as having liquid memory, these formulas respond to brush movement while becoming more stable when left undisturbed.

Explore professional ranges including Yoshi Jelly PRO, MAKEAR Geltix, Excellent Pro Builder Gel with Thixotropy and Saute Nails One Touch.

These systems offer different working properties, so always check the individual product information before choosing a technique.

No File Builder Gels

Save time on finishing with No File Builder Gels designed to help create the finished nail structure during application.

These products support techniques where careful placement and leveling can minimise the filing required after curing.

Depending on the formula and technique, some applications may require only small refinements or no additional filing.

Not every self leveling gel is intended for no-file work, so select products specifically recommended for the technique.

Coloured Builder Gels for Natural-Looking Nails

Builder gel doesn't always need to be clear.

Explore coloured builder gels in soft pink, nude, beige, milky white and cover shades for structured manicures with a natural finish.

These shades are particularly popular for French nails, Baby Boomer designs, clean manicures and natural nail overlays.

For more decorative sets, discover selected shimmer, glitter and effect builder gels that combine structure with additional colour or sparkle.

Coverage varies between formulas, from sheer natural shades to more opaque camouflage gels.

Builder Gel in a Bottle

For convenient brush-on application, discover builder gel in a bottle and BIAB-style formulas.

These products combine a practical bottle-and-brush format with building or strengthening properties.

Depending on the formula, they can be useful for natural nail overlays, shorter structured manicures and efficient salon refills.

Explore bottle builder systems including Saute Nails BiB Level Up and other professional brush-on building gels.

Not all bottle builder gels have the same hardness or flexibility, so check the recommended uses before choosing one for extensions or natural nail strengthening.

Hard Builder Gels for Extensions

For longer nail extensions and more demanding structures, choosing a suitable hard builder gel is important.

Some UV/LED builder systems are developed to maintain a strong nail structure during extension work, while more flexible formulas are better suited to different natural nail requirements.

Explore professional builder gels for forms, tips, reconstruction and refills, selecting the gel according to the required length, hardness and application method.

How to Choose the Right UV Builder Gel

When comparing professional nail gels, consider:

  • Consistency: Self leveling, jelly or thixotropic
  • Hardness and flexibility: Choose according to the natural nail and intended structure
  • Application: Bottle builder gel or traditional pot gel
  • Colour: Clear, milky, nude, pink, white or decorative
  • Technique: Natural nail overlay, strengthening, extension or refill
  • Preparation: Compatible base products and bonding requirements
  • Curing and removal: Follow the individual manufacturer's instructions

Some builder gels require a separate base coat, while others allow specific applications without one. Removal requirements can also differ between hard and soak-off formulas.

Frequently asked questions

What are builder and UV gels used for?

Builder and UV gels are professional nail enhancement products used for strengthening natural nails, creating structured overlays, building extensions and completing refills. Different formulas offer different levels of hardness, flexibility and control, so the appropriate gel depends on the service.

What is the difference between self leveling and jelly builder gels?

Self leveling builder gels smooth themselves during application, helping create an even nail surface. Jelly builder gels are thicker and more stable, providing greater control during shaping. Some thixotropic gels also combine stability with controlled leveling.

Do I need a base coat under builder gel?

It depends on the individual builder gel. Some systems require a separate base or bonding layer, while others have specific application techniques that do not. Always follow the manufacturer's instructions for preparation, curing and removal.
