Everything You Need to Know About UV Builder Gel Nails

What Is a UV Gel Builder Used For?

If you're a professional nail tech specializing in nail extensions, overlays, or nail repairs, a UV builder gel is an essential part of your toolkit. Unlike regular gel nails, builder gel has a hard gel structure similar to acrylic, but it must be cured in UV LED lamp. It’s perfect for:

✔ Extending nails with forms or tips
✔ Strengthening and repairing damaged nails
✔ Creating sculpted, structured designs
✔ Building a strong yet natural-looking nail plate

How to use UV Builder Gels?

We apply the Semilac Builder Gel to a properly prepared nail plate. We recommend using a primer. We apply the gel to the previously applied Semilac Extend Base. We cure it in UV LED lamp. If after applying the builder gel we do not apply a colored gel polish, we can also end the styling after developing the product at this stage by applying a glossing product to the gel.

Why Nail Techs Love It:


✔ Reduces burning sensation during curing for maximum comfort
✔ Self-leveling properties for smooth, even application
✔ Strong yet flexible structure – more durable than regular gel nails
✔ Perfect for beginners & pros – easy to work with

What Is a Builder Gel Overlay?

A builder gel overlay is a great solution for clients with short, weak, or brittle nails. The hard structure of UV builder gel strengthens the nail, creating a correct C-curve that protects against chipping and breakage. Overlays can also help grow out natural nails by adding a layer of protection while maintaining a natural, elegant look.
