Mastering Builder UV Gels: A Pro’s Guide to the Semilac Range

If you’ve already mastered UV gel manicures and feel ready to level up your nail skills, it’s time to explore the world of builder gels. Whether you're looking to strengthen natural nails, add length, or perfect your nail architecture - builder gel is your new best friend.

In this post, we’ll walk you through what builder gel is, why it’s a game-changer, and how to use Semilac’s builder gels step by step. Let’s get started!

What is Builder Gel?

Builder gel (often referred to as ‘hard gel’) is a thick, self-levelling product used to create a strong, durable nail structure. Unlike soft gels (such as traditional UV gel polish), builder gels can be used to:

Strengthen weak nails
Extend the nail plate using tips or forms
Reconstruct broken or uneven nails
Sculpt perfect apexes and curves for long-lasting wear

Builder gels are cured under a UV or LED lamp, creating a long-lasting, flexible finish that supports nail health when applied correctly.

How to Apply Builder Gel - Step by Step

1. Prep the Nails

This is key to long-lasting results.

Gently push back cuticles with a cuticle pusher.
Trim excess skin if needed using cuticle clippers.
Shape the nail with a file and lightly buff the surface to remove shine.
Clean the nail plate using Semilac Nail Cleaner and a cotton pads.
Apply primer if required for your nail type.

2. Apply the Base

Apply a thin layer of Semilac Base and cure under your UV/LED lamp according to product instructions.

Tip: If your nails are weak, opt for Semilac Fiber Base to add extra strength and grip.

3. Place Nail Forms (If Extending)

If you’re extending the nail, now is the time to secure your nail forms just beneath the free edge. Ensure they're aligned properly to achieve a symmetrical shape.

4. Apply the Builder Gel

Using a brush for UV gel application, pick up a small bead of builder gel.
Apply a thin slip layer first, then without curing, place a larger bead and build the apex.
Work gently, guiding the UV gel into shape. Allow the product to self-level.
Cure in your UV/LED lamp (usually 60–90 seconds, depending on lamp strength and gel thickness).

Tip: Work one nail at a time for full control, especially when building apexes.

5. Refine the Shape

Once cured and cool to the touch:

Wipe off the sticky layer using cleaner.
File the nail to your desired shape (almond, square, ballerina, etc.)
Use a buffer to smooth the surface if necessary.

6. Apply Colour or Finish

You can leave your builder gel nails natural or paint over them with Semilac UV gel polish.
Finish with a Top No Wipe for high shine or Top Mat Total for a velvety matte look.
Cure again under the UV/LED lamp.
Wipe (if necessary) and massage cuticle oil into the skin around the nail.
