Nullarbor - 59 - Professional Biab builder gel - 15ml
Still, vast, enduring. Drawing its name from Australia's expansive limestone plateau, Nullarbor is a true cool grey-beige that sits at the intersection of neutral and statement. This cream finish feels like the natural extension of your nail bed—soft enough to blend, defined enough to build. The BIAB technology strengthens nails while this restrained tone provides structure and professionalism that never demands explanation.
Nullaarbor is the foundation shade for professionals who build their aesthetic around precision and reliability. Wear alone on natural nails for an understated elegance, or layer over other OPAL shades for depth and complexity. The smooth cream finish catches light evenly, creating a polished appearance that works in any setting—from boardroom to gallery opening. This is a shade that rewards close inspection without announcing itself.
Skin Tones: Works beautifully on all skin tones; particularly striking on deeper complexions and those with warm undertones.
Best Worn For: Executive presentations, minimalist manicures, neutral nail art base, corporate events, daily office wear, professional photography.
Pairs With: Flannel Flower (No. 57), Barossa (No. 60)
How To Use
Start with clean, dry nails. Remove any existing gel, polish, or product completely using an appropriate remover.
Removes natural oils, dust, and any moisture — all of which cause lifting. Then apply nail bond or primer if needed.
Apply a thin, even layer of OPAL Gel Base Coat over the entire nail. Cure immediately under your LED lamp.
Using the OPAL Builder Gel brush, scoop a small bead, place it in the centre of the nail and allow it to self-level for 2–3 seconds before spreading. Cure under LED for 60 seconds.
Apply a second, slightly larger bead for your desired strength and length extension. Cure for 60 seconds.
Using a 100/180-grit Opal nail file, shape the free edge to your desired finish — square, oval, almond, coffin, or round. Work in one direction to prevent cracking.
If applying gel polish colour, apply a thin, even first coat and cure for 60 seconds. Follow with a second coat for full opacity and cure again.
Apply OPAL Gel Top Coat in a smooth, even layer over the entire nail surface. Cap the free edge to seal the product and prevent tip wear. Cure for 60 seconds.
Pro Tip
Allow each bead to self-level for 2–3 seconds before spreading. Work in thin, controlled layers — it’s easier to add thickness than to remove it. Always cap the free edge with your top coat to prevent tip wear.
