How to Apply Brush On Builder X Gel for Natural Nails

Quick answer

Apply Brush On Builder X gel to clean, prepped natural nails in thin layers, curing each under a UV/LED lamp for a strong, flexible overlay or subtle extension.

Step-by-step application

1. Prep the natural nail: Push back cuticles, gently buff the nail surface to remove shine, and wipe with alcohol or a nail dehydrator. Avoid over-filing to prevent weakening the nail. Skipping dehydration is the top cause of lifting.
2. Apply a thin base coat: Brush a thin layer of Base Gel from the kit onto each nail. Cap the free edge. Cure under a UV/LED lamp according to the gel's instructions (typically 30-60 seconds). A thick base layer can pool in the sidewalls and cause uneven curing.
3. Build the apex with Brush On Builder X: Using the built-in brush, apply a small bead of Builder X at the center of the nail. Gently stroke it toward the cuticle and free edge, forming a gentle apex (thicker center) for strength. Cure immediately. Work in thin layers; a single thick layer creates heat spikes and may not cure fully.
4. Shape and refine (optional): If needed, apply a second thin layer of Builder X to adjust shape or add length. Cure again. Wipe off the tacky dispersion layer with alcohol if the next step is not a no-wipe top coat. Use a 180-grit file to gently shape the free edge only after the final cure.
5. Seal with top coat: Apply a thin layer of Top Gel, cap the free edge, and cure. Wipe off the tacky layer with alcohol if using a standard top coat, or skip wiping if using a no-wipe formula. Capping the free edge prevents chipping and extends wear time.
