BIAB - Builder in a Bottle

Shills Professional Builder Gel (BIAB) is a salon-grade, self-leveling builder gel designed to create strong, balanced nail structure with a smooth, cushiony feel. Its controlled viscosity helps you sculpt apex and length on forms or overlays, while resisting chips and daily wear. Leaves a refined finish ready for top coat.

Prep: Clean nails, push back cuticles, buff lightly, remove dust; apply dehydrator and primer.
Base Coat: Apply thin base coat; cure (LED 1 min / UV 2–3 min for darker shades).
Form/Tip (if needed): Apply and secure form or tip.
Build Layer 1: Apply thin builder gel layer; cure (LED 1 min / UV 2 min).
Build Layer 2: Add thicker layer to build apex/structure; cure (same timing).
Refine: File and shape; remove dust.
Seal: Apply top coat (glossy or matte); cure (LED 1 min / UV 2–3 min).
