14 Day Mani Primer & Builder Gel Duo - For Stronger, Longer-Lasting At-Home Gel Nails

Say goodbye to weak, short-lasting manicures.
The 14 Day Mani Primer & Builder Gel Duo is your go-to for stronger, salon-quality nails at home.
Designed to enhance nail strength and improve gel adhesion, this two-step combo delivers long-lasting, flawless results.
Whether you’re new to gel nails or a seasoned pro, this duo makes a powerful difference to your nail routine.

It’s perfect for building strength, adding shape, and extending natural nails without causing damage.
Unlike many builder gels, ours doesn’t need a base coat, making application faster and more user-friendly.
The formula self-levels for a smooth, even finish and cures under LED light in just 60 seconds.
No lumps, no uneven surfaces - just beautifully structured nails, every time.

Choose from 12 stunning builder gel shades by customising your duo!

Pair it with our Perfect Prep™ Primer, specially formulated to improve adhesion and reduce lifting.
It’s ideal for oily nail beds or clients who experience premature chipping or peeling.
This primer creates a tacky base layer that helps gel products stay put longer.
Together, these products create the ultimate base for long-lasting, professional-quality gel manicures at home.

This duo is beginner-friendly but also trusted by pros.
It offers maximum control and stunning results for every skill level.
Perfect for those who want natural nails with added strength or longer enhancements without the use of acrylics.
It’s also ideal for nail biters or anyone growing out weak, damaged nails.

The Builder Gel is available in multiple shades to suit every style and nail tone.
From classic sheer pink to natural beige, you can choose the finish that suits your look.
Its thick consistency allows for easy control, especially when sculpting or shaping nails.
You can use it alone for a natural look or as a base under your favourite gel colour.

To apply, start with clean, prepped nails and apply one coat of Perfect Prep™ Primer.
Let the primer air-dry for a few seconds - no need to cure it under a lamp.
Then, apply a thin layer of Builder Gel and cure under an LED lamp for 60 seconds.
You can add a second or third layer if building length or strength.
Finish with your favourite gel polish and top coat for salon-worthy shine.
