Grevillea - 38 - Professional Biab builder gel - 15ml
Fresh, refined, and inspired by the architectural brilliance of Australia's native grevillea bloom, this is a soft olive-green with unexpected sophistication. Named for the spider-like flowers that attract native birds across the continent, Grevillea captures nature's intelligence in a muted, grey-toned green. As a builder gel, it layers with precision, creating both colour and the structural support that defines professional nail work.
Grevillea is for the thoughtful professional—someone who appreciates nuance over noise. Wear it for presentations where subtlety strengthens your message, for garden events, for moments when understated elegance proves your authority. The BIAB formula builds nail strength with every layer, while the creamy finish ensures flawless coverage that photographs beautifully. This is the colour of someone who knows exactly what she's doing.
Skin Tones: Luminous on cool undertones and fair complexions; stunning on olive skin; creates gentle contrast on warmer, deeper skin tones.
Best Worn For: Botanical events, corporate presentations, garden weddings, sustainability-focused meetings, creative workshops, everyday professional wear
Pairs With: Barossa Stone (No. 42), Coober Depth (No. 40)
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.
