I started by purchasing a trio kit that contained a base, lakur, and this top coat and immediately my nails felt less weak and the polish lasted at least a week before chipping. I recently used a normal base coat and noticed at work (I work in a bakery) that my nails felt very weak and bendy. So I came home scraped up what was left of this Nail hardener base coat, and I could definitely tell the difference the next day at work. I would recommend this to anyone, especially natural nail people, who can’t or don’t want to do gel or acrylic, or even if you’re just taking a little break from that stuff. They are a little high in price but it is well worth it. I just get one at a time, although some of their bundles are a better deal. Review: Held up for a week - Great base coat - held up for a week, even with my weak nails. ## Features - 2-in-1 strengthener and base coat: Nail hardener and strengthener - Nail hardening polish: Biotin restores strength - Prevents chipping and breakage: Nitrocellulose shields and protects - Nail growth polish: Florium Complex encourages healthy regrowth - Primes nails for polish: Grips on to polish to make it last ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 942 Reviews | ## Product Details - **Brand:** LONDONTOWN - **Item Form:** Liquid - **Item Weight:** 12 Grams - **Liquid Volume:** 0.4 Fluid Ounces - **Specialty:** Protein,Hardener,Extend ## Images ![LONDONTOWN kur Nail Hardener & Base Coat Nail Polish - Image 1](https://m.media-amazon.com/images/I/715Vg2HXCuL.jpg) ![LONDONTOWN kur Nail Hardener & Base Coat Nail Polish - Image 2](https://m.media-amazon.com/images/I/61uXDHolinL.jpg) ![LONDONTOWN kur Nail Hardener & Base Coat Nail Polish - Image 3](https://m.media-amazon.com/images/I/61GnPAxXwtL.jpg) ![LONDONTOWN kur Nail Hardener & Base Coat Nail Polish - Image 4](https://m.media-amazon.com/images/I/710nSAEKjfL.jpg) ![LONDONTOWN kur Nail Hardener & Base Coat Nail Polish - Image 5](https://m.media-amazon.com/images/I/71z0E3VRioL.jpg) ## Questions & Answers **Q: How is Nail Hardener & Base Coat different from regular base coats?** A: This multitasking formula doubles as both a nail strengthener and a base coat. **Q: Is Nail Hardener & Base Coat safe for all nail types?** A: Yes.

I started by purchasing a trio kit that contained a base, lakur, and this top coat and immediately my nails felt less weak and the polish lasted at least a week before chipping. I recently used a normal base coat and noticed at work (I work in a bakery) that my nails felt very weak and bendy. So I came home scraped up what was left of this Nail hardener base coat, and I could definitely tell the difference the next day at work. I would recommend this to anyone, especially natural nail people, who can’t or don’t want to do gel or acrylic, or even if you’re just taking a little break from that stuff. They are a little high in price but it is well worth it. I just get one at a time, although some of their bundles are a better deal. ### ⭐⭐⭐⭐⭐ Held up for a week *by M***O on April 5, 2026* Great base coat - held up for a week, even with my weak nails. ### ⭐⭐⭐⭐⭐ The shine that stays and does not peel off like the others so it's worth the extra few dollars *by K***R on June 30, 2026* All right finally I found one that does not peel off. You know that clear stuff you put on your nails and it looks so good and shiny and then by the evening they peel off in one big swoop? Well this one stays on for days and days and looks nice day after day even after swimming ## Frequently Bought Together - LONDONTOWN kur Nail Hardener and Base Coat, 0.4 Fl Oz (Pack of 1) - LONDONTOWN kur Illuminating Nail Concealer, Vegan, Cruelty Free, Gluten Free, Paraben Free Sheer Nail Polish Long Lasting Brightening Nail Care - LONDONTOWN kur Nail Ridge Filler - Smoother - Strengthener - Filler for Damaged Uneven Nails - Fortifying, Self Leveling Base, Vegan, Cruelty Free, Paraben Free, 0.4 fl oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/14807632-londontown-kur-nail-hardener-and-base-coat-nail-polish](https://www.desertcart.hr/products/14807632-londontown-kur-nail-hardener-and-base-coat-nail-polish) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-13*
