Karo Builder Gel for Nail Modeling and Extension

Karo Builder Gel is a professional nail modeling gel used for nail extension, overlay, and structure building on the natural nail or nail form. This collection carries the Karo Builder Gel range available at Beauty Hunter, covering numbered shades and a Clear option in 15 ml and 30 ml jar formats. Products are suited to nail technicians who perform hard gel nail extension and overlay services and work within the Karo product system.

The collection covers Karo Builder Gel in a numbered shade range and a Clear formula, with selected shades available in both 15 ml and 30 ml jars. The Clear builder gel suits nail technicians who build structure without adding color, while the numbered shades suit technicians who prefer a tinted or camouflage builder gel for the extension base.

Karo Builder Gel Shades and Sizes

The collection includes Karo Builder Gel in a numbered shade range and a Clear option, across two jar sizes.

Clear Builder Gel

The Karo Builder Gel Clear is a transparent formula suited to nail extension and overlay where no color or tint is added at the builder gel step.

• Karo Builder Gel Clear — 15 ml and 30 ml

The Clear formula is available in both jar sizes, suited to nail technicians who use a clear builder gel for all extension services or who apply a colored gel polish over the extension. Select the 15 ml for lower-volume use or trial; select the 30 ml for higher-volume workstation use.

Numbered Shade Builder Gels

The Karo Builder Gel numbered shade range covers tinted and camouflage builder gel options in a selection of numbered shades. Shade numbers are non-sequential, indicating that selected shades from the Karo Builder Gel range are available in this collection.

• Available in 15 ml only: №1, №03, №04, №6, №16, №18
• Available in 30 ml only: №5, №7, №17
• Available in both 15 ml and 30 ml: №02, №8, №9

For the specific color direction and finish of each numbered shade, review the Karo shade imagery or individual product listings before selecting. Numbered shades suit nail technicians who prefer a tinted or camouflage builder gel that reduces the need for a separate base color layer. Shades available in both sizes (02, 8, 9) allow technicians to stock the same shade in a trial size and a professional volume size.

How to Choose Karo Builder Gel

Selecting the right Karo Builder Gel depends on the desired finish at the builder gel step and the preferred jar size.

• Clear vs. tinted — for a transparent extension base, select Karo Builder Gel Clear (15 ml or 30 ml). For a tinted or camouflage extension base, select from the numbered shade range. Review Karo shade imagery for each shade number before selecting.
• Jar size — the 15 ml jar suits trial use, lower-volume workstation use, or stocking a wider shade range in smaller quantities. The 30 ml jar suits higher-volume use of a confirmed shade. Shades 02, 8, 9, and Clear are available in both sizes; shades 1, 03, 04, 6, 16, 18 are available in 15 ml only; shades 5, 7, 17 are available in 30 ml only.

For a professional nail extension workstation, stocking Karo Builder Gel Clear in 30 ml covers the primary extension structure requirement. Adding one or more numbered shades in 15 ml allows the technician to offer tinted or camouflage extension options without committing to a full 30 ml of each shade.

How to Use Karo Builder Gel

Apply Karo Builder Gel to the prepared nail plate or nail form to build the extension structure and shape. Apply in layers, shaping the gel before curing each layer under a UV/LED lamp according to the manufacturer's instructions. For specific curing times, layer thickness, and application technique, refer to the Karo manufacturer's instructions for each shade and jar size.
