Method 1
Repair with Solid Gel Polish

Solid gel polish is perfect for minor cracks and chips. It provides precise application and strong results.

Step 1: Prep the nail. Clean the nail with alcohol and lint‑free wipes. If there is a sharp edge, carefully clip it to prevent further tearing.
Step 2: Buff and etch. Lightly buff the entire nail surface, focusing on the area around the break. Do not buff the crack itself. This can weaken it further.
Step 3: Dehydrate. Apply nail dehydrator or isopropyl alcohol to remove moisture. This prevents lifting and ensures your repair lasts.
Step 4: Apply the repair. Apply base coat and cure. Then use a small bead of solid gel polish over the break, pressing it into the crack to bridge both sides. Smooth over the entire nail and cure thoroughly.
Step 5: Finish. File to smooth any bumps, then apply colour gel and top coat as usual.
Method 2
Repair with BIAB (Builder in a Bottle)

BIAB is the professional choice for serious breaks that need maximum reinforcement.

Step 1: Prep the nail. Clean, lightly buff (avoiding the crack), and apply dehydrator. Same as Method 1.
Step 2: Create foundation. Apply a thin base coat and cure.
Step 3: Build the repair. Apply a medium‑thick coat of BIAB over the entire nail. Pro tip: hold your finger upside down for 10‑20 seconds. Gravity pulls the product into a perfect smooth apex over the break.
Step 4: Final touches. Cure completely, file to the desired shape, then apply colour or wear as a natural glossy look.

Pro Tips
Professional Tips for Perfect Repairs
Don't skip prep. 90% of a long‑lasting repair is in the preparation. Dehydrating is non‑negotiable for professional results.
Less is more. Start with a small amount of product. You can always add more, but filing away excess can weaken the repair.
Seal the edges. When applying top coat, swipe it under the free edge of the nail to fully seal the repair and prevent lifting.

Answers
Frequently Asked Questions

How long will a gel or BIAB nail repair last?

A properly done repair can last until your nail grows out completely. It is as strong as your other gel nails when applied correctly.

Is the tea bag method better than gel repair?

No. The tea bag method is a temporary fix that is not waterproof or long‑lasting. Gel and BIAB repairs create a flexible, waterproof shield that fully encapsulates the break.

What if my nail is bleeding or very painful?

Do not apply any gel products to open wounds or bleeding nails. Clean gently, apply antiseptic, and let it heal completely before attempting any repair.

Can I repair natural nails without extensions?

Absolutely. Both BIAB and solid gel polish are perfect for adding strength to natural nails and repairing breaks without extensions.
