Why is my Builder Gel Lifting? 5 Common Mistakes and How to Fix Them

There is nothing quite like the heartbreak of spending your Sunday afternoon perfecting a BIAB (Builder in a Bottle) manicure, only to see a corner start to peel or "lift" forty-eight hours later.

Lifting isn't just annoying; it’s a health hazard for your nails. Moisture can get trapped under the lifted gel, creating a breeding ground for bacteria. If you want your builder gel to go the distance (we’re talking 3+ weeks of perfection), you need to avoid these five common pitfalls.

1. The "Invisible" Cuticle

This is the #1 reason for lifting. Even if your cuticles look tidy, there is often a thin layer of "invisible" dead skin cells on the nail plate.

The Mistake: Applying BIAB over the cuticle. Gel will stick to your nail, but it will not stick to your skin. As soon as that skin moves or sheds, the gel pulls away. The Fix: Use a cuticle pusher and a fine-grit buffer to ensure the nail plate is 100% clear of skin. A "dry manicure" technique is best here!

2. Inadequate Dehydration & Priming

Your nails are naturally oily. If you don't remove those oils, your builder gel is basically trying to stick to a slip-and-slide.

The Mistake: Skipping prep products or using "2-in-1" solutions that don't quite do the job. The Fix: Use a dedicated Nail Prep Dehydrator followed by an Acid-Free Primer. This duo ensures the nail is bone-dry and creates a "velcro-like" bond for the gel.

3. Applying It Too Thick (The "Bulky" Mani)

We all love a strong nail, but more isn't always better.

The Mistake: Flooding the side walls or applying one massive glob of builder gel. Thick layers often don't cure all the way through, leaving "mushy" gel underneath that inevitably lifts. The Fix: Work in layers. Apply a thin "slip layer," then build your apex (the strength point) with a smaller bead of gel. If you're new to this, check out our Guide to Applying BIAB at Home.

4. Forgetting to "Cap the Free Edge"

Think of your nail like a sandwich. If the edges aren't sealed, the "filling" (the gel) is going to spill out or get snagged.

The Mistake: Ignoring the very tip of the nail. This is where we use our hands most—typing, opening cans, or texting. Without a seal, the gel starts to pull back from the tip. The Fix: Every time you apply a layer—base, builder, or top coat—run your brush horizontally along the very front edge of the nail to "cap" it.

5. Using an Underpowered Lamp

Not all UV/LED lamps are created equal. Builder gel is highly pigmented and thick; it needs a specific wavelength to turn from liquid to solid.

The Mistake: Using a small "mini" lamp or an old lamp with dying bulbs. If the gel isn't fully polymerised, it will lift within days. The Fix: Ensure you are using a professional-grade lamp (at least 36W). If you are using a HEMA-Free BIAB, full curing is even more vital for your skin safety!

Still Lifting? Check Your Lifestyle!

Sometimes, the application is perfect, but our daily habits get in the way.

• Hot Water: If you spend a lot of time with your hands in hot water (doing dishes or long baths) without gloves, the heat can cause the natural nail to expand and contract, breaking the bond.

• Nails as Tools: Remember: your nails are jewels, not tools! Don't use them to scrape off labels or open soda cans.
