How to Apply Apres Gel-X Nail Extensions

Prep your natural nails

Remove any existing polish completely. Gently push back your cuticles with a wooden or metal cuticle pusher — do not cut living skin. Lightly buff the shine off the nail plate with a buffer (you want matte, not thinned-down). Clean away any dust with a lint-free wipe.

Wipe each nail with Gel-X Prep or 91% isopropyl alcohol on a lint-free pad. This removes oils and residue that would compromise adhesion. After this step, don't touch the nail plate with bare fingers — skin oils immediately re-contaminate the surface.

Size all ten tips before touching any gel

Lay out ten tips matched to ten fingers before you open any gel product. The tip should cover the full nail plate from sidewall to sidewall with no gap and no overhang. If a tip is slightly too wide, file the edges down from the sides with your 180-grit file.

Aprés Gel-X Tips come in sizes 0 through 11 (and half sizes in the 2.0 line — 4.5, 5.5, and 6.5 — which offer a more inclusive fit for wider nail beds). Size up if you're between sizes: a tip that's marginally too wide can be filed; a tip that's too narrow will always show a gap at the edge.

The Gel-X Tips 2.0 also have a thinner base edge than the originals, for a more natural-looking cuticle line. If you're new, the 2.0 tips are the current recommendation.

Apply pH Bonder

Apply a thin layer of Aprés pH Bonder to each nail plate. The bonder dehydrates the nail and balances its pH, creating the ideal surface for the primer and gel to adhere to. Let it fully air-dry — 30 to 60 seconds. Do not cure it under the lamp; it air-dries only.

Apply Non-Acidic Gel Primer

Brush a thin layer of Aprés Non-Acidic Gel Primer over each nail plate. This step is what separates sets that last three weeks from ones that lift in ten days — it creates a chemical bond between the natural nail and the gel. Let it air-dry fully (it will look slightly tacky and glossy — that's correct). Do not cure.

Apply Extend Gel to the natural nail and cure

Brush a thin, even layer of Aprés Extend Gel across the entire natural nail plate — from cuticle to free edge. Keep a 1mm gap from the cuticle and sidewall skin. Don't flood the cuticle area; any uncured gel on skin is both a sensitization risk and a lifting risk.

Cure under your UV/LED lamp for 30 seconds. You're not trying to fully cure a thick layer — this is a base bond coat that seats the tip onto a sticky, compatible surface.

Fill the tip and place it

Fill the inner well of the pre-sized tip with Extend Gel. You want enough gel to wet the full inner surface without it flooding out the sides — roughly a pea-sized amount for short tips, slightly more for longer ones.

Align the tip's inner edge with your cuticle line. Press down at a 45-degree angle from the free edge toward the cuticle, rolling the tip down to seat it flat without trapping air bubbles. Hold 5 to 10 seconds with firm, even pressure. Wipe any gel squeeze-out from the sidewalls with a lint-free wipe immediately — before curing.

Flash cure, then full cure

Flash cure for 30 seconds under the lamp to lock the tip's position, then flip your hand and do a full 60-second cure from above to fully polymerize the gel. Repeat steps 5 through 7 for each finger — don't try to place all ten tips before curing; gel left uncured under a tip can cause adhesion failure.

Seal the underside and cure

After all ten tips are placed and cured, apply your top gelcoat to the underside of each free edge and cure for 30 seconds. This seals the underside against moisture and debris, which is one of the most overlooked steps for extending wear. It also prevents the free edge from lifting from beneath.

Shape and refine

With a 180-grit file, shape each tip to your desired length and shape — file in one direction, not back-and-forth. Reduce length from the free edge, then shape the sides. Finish with a 240-grit file or 4-way buffer to smooth any file marks and refine the surface. Dust off thoroughly with a dry brush or lint-free wipe before the next step.

If you want to adjust the nail shape from what the tip provides — for example, filing a natural almond slightly squarer — do it now before any color goes on. For a guide on which shape works best for your hand type, see our Gel-X nail shape guide.

Apply gel color (optional)

Apply a thin layer of gel base coat, then your chosen gel polish color, curing each layer under the lamp according to the gel's instructions (typically 30 seconds per coat). Two thin coats give better color saturation and fewer bubbles than one thick coat. Finish with a non-wipe top gelcoat and a final cure — the top coat is what gives you the high-gloss, chip-resistant finish.

Not feeling color? Wear the set as-is with just the top coat — the natural or clear tip finish looks clean and polished on its own.

Clean up and moisturize

Use a clean-up brush or lint-free wipe dipped in rubbing alcohol or acetone to remove any gel residue from the skin around the cuticle or sidewalls. Take your time here — clean edges make the whole set look more professional.

Finish with cuticle oil massaged into each nail and the surrounding skin. This is the step most people skip and shouldn't — daily cuticle oil is the single biggest thing you can do to extend your wear time and keep your natural nails healthy underneath the set.
