LONDONTOWN Grip Lock Base Coat — tacky nail primer with biotin for gel-like long wear

LONDONTOWN Grip Lock Base Coat is a tacky, plumping nail primer that strengthens nails and creates a sticky foundation to dramatically improve polish adhesion and resist chipping.

Designed as a dual-action base, Grip Lock both primes and nourishes. Its flexible, tacky formula mimics the bond of a gel base while remaining a traditional polish product—so you get extended wear and reduced lifting without requiring a lamp. Enriched with biotin, vitamins, antioxidants, and LONDONTOWN’s Florium Complex, the base coat helps fortify nails while creating the ideal surface for lakur, polish, or decals to latch onto for longer-lasting manicures and pedicures.

How does Grip Lock make polish last longer?

Grip Lock forms a slightly sticky layer that improves mechanical adhesion between the natural nail and whatever color or decoration you apply. Because the formula is flexible, it moves with the nail instead of cracking off, which cuts down on chips and peeling. The result is a salon-quality hold that prolongs shine and smoothness.

• Creates a tacky primer that helps polish bind securely to nails
• Flexible film minimizes cracking and edge lifting
• Works with regular polish, lakur, and nail decals
• Pairs with a top coat like Gel Genius to maximize wear

What ingredients care for my nails while I wear polish?

Grip Lock blends strengthening actives with botanical support so your manicure is protective as well as long-wearing. Biotin and vitamins work to reinforce nail structure, while antioxidants help defend against environmental stressors. The Florium Complex balances moisture and resilience to keep nails looking healthier both during and after wear.

• Biotin and vitamins to help fortify nail plate
• Antioxidants to protect against oxidative damage
• Florium Complex to hydrate and maintain nail flexibility
• Cruelty-free, vegan, and free from common harsh additives

How should I apply the base coat for best results?

Start with clean, dry nails for optimal grip. Apply one thin, even coat of Grip Lock and allow it to set for 1–2 minutes before applying your color. For extended longevity, follow with 1–2 coats of your chosen lakur and finish with Gel Genius Top Coat; using Pre-Prep Nail Dehydrator beforehand can further improve adhesion.

• Begin with clean nails; use Pre-Prep Nail Dehydrator for oil removal
• Apply one thin coat, wait 1–2 minutes to set
• Layer 1–2 coats of polish, then seal with a top coat
• Use for manicures and pedicures to reduce chipping

Will this base coat damage natural nails or feel like a gel?

Grip Lock is formulated to deliver a gel-like hold without the curing step or harsh treatments. It’s flexible rather than rigid, which helps protect the natural nail by reducing stress at the edges. The clean, botanical-forward formula avoids many troubling additives, supporting healthier appearance versus conventional strengthening systems that can be overly hardening.

• Provides gel-like adhesion without UV curing
• Flexible finish reduces stress and cracking
• Free from formaldehyde, toluene, phthalates, camphor, and similar ingredients
• Leaves nails hydrated and fortified rather than brittle

Who is this for: Grip Lock Base Coat is ideal for anyone who wants longer-lasting polish with improved chip resistance—perfect for frequent polish wearers, at-home mani lovers, and professionals seeking a dependable primer that also cares for the nail. It suits those who prefer clean, cruelty-free formulations and want a base that supports healthier-looking nails while extending the life of their lacquer or nail art.
