View full detailsAdd length and strength to your long-lasting manicure or pedicure with our Builder in a Bottle (BIAB) products. From bond enhancers to top coats, we’ve got everything you need to enjoy the durable, glossy results this nail invention can achieve. Pull off a fabulous manicure or pedicure that looks great and is long-wearing. Whether you’re working with long or short nails, prefer classic colours or glitter tips, our Australian builder gel in a bottle products will provide you with everything you need for a professional result.
If you’re all about nails that stay lustrous and hold up through your everyday hustle, BIAB is the mani upgrade you’ll be obsessed with. Here’s why builder gel shades are becoming a must-have in every nail tech's toolkit:
Strength without the stress
Nail builder gel is tougher than regular nail polish thanks to its thick, self-levelling formula. With the right care, BIAB nails will stay fresh and chip-free for up to three to four weeks before it’s time for a removal, infill or refresh. Whether you're typing all day, running errands or juggling kids and chores, BIAB helps your mani stay flawless through it all.
One product, endless looks
Builder gel is also flexible (literally and creatively). You can wear it alone for a natural, clean-girl nail look or layer it under your fave gel polish for something bolder. With a growing range of pigments and finishes, there’s a shade or style to match every mood, outfit or occasion.
Nail care with a gentle touch
Builder gel bonds beautifully without wrecking your natural nails and has a far less aggressive removal process than acrylic nails. At NSI Australia, our BIAB formulas are free from harsh toxins (it’s HEMA-free, MMA-free and 11-toxin free), so your nails stay sturdy and supported underneath.
At NSI Nails, we offer an expansive range of products for all your builder gel in a bottle needs. Shop our collection of ready-made kits or select from our individual products, including builder extension gels, bond primers and base coats. Use builder in a bottle on natural nails as an overlay, sculpt to form nail extensions or pair with your favourite gel products to enhance results. We have both clear and coloured builder gel shades available to suit your style.
Whether you’re looking to create a long-lasting manicure for your next holiday or strong, everyday nails, our builder in a bottle products make it easy to DIY like a pro.
To get that flawless BIAB finish, start by prepping your natural nails with a bond enhancer and base coat to reduce lifting and peeling. Then, apply your builder gel in a bottle in thin, even layers. Don’t forget to cure each layer under a UV or LED lamp. Once you’ve built your shape, seal it all in with a reliable top coat for that lasting shine.

Builder in a bottle is a builder gel used to enhance the length, strength and thickness of nails. Sometimes referred to as ‘BIAB nails’ in-salon, it can be used on natural nails for a chip-resistant overlay or to create extensions or enhancements. It provides a long-wearing, glossy finish without compromising the health of the nail bed underneath.
Builder gel in a bottle helps nails grow by protecting them from breaking and chipping. While it doesn’t stimulate nail growth, the durable coating provides resistance for nail biters to help break the habit while the natural nail grows strong and long underneath. It can also be used to create the appearance of longer nails by extending beyond the tips of your manicure or pedicure.
Gel polish is a lightweight, glossy fave that adds a pop of colour and shine. It’s flexible, chip-resistant and creates a fresh, natural look that lasts a couple of weeks — no touch-ups needed!
On the other hand, builder gel is thicker and all about giving your nails extra shape and length. It’s perfect for reinforcing weak nails, creating overlays or building dreamy nail extensions. Plus, you can file and sculpt it to your heart’s content, making it versatile for bolder looks.
Generally, builder gel is seen as a gentler option for your natural nails. It’s easier to apply and remove, and its flexible formula means it moves with your nails, helping to reduce breakage. Acrylics are long-wearing, but they often require heavier filing during application and removal, which can put more stress on your natural nails over time. So if you're after strength and a little extra nail care, nail builder gel is a fabulous choice.
