A game-changer that ensures extended, chip-free wear for lakurs and gel polish. Designed as a follow-up step after Pre-Prep Nail Dehydrator (but before base coat application), this powerful polish bonder ensures maximum adhesion of the base coat to the nail’s surface. A non-acid formula helps prevent damage to the nail plate, and the concrete-like grip will give lakurs actual, gel-like wear or prevent gels from lifting.
12 ml / .4 fl oz
Store in a cool, dry place. Apply to clean nails (or directly after Pre-Prep Nail Dehydrator for best results). Once fully dry, apply base coat or gel polish as usual.

WHY
IT'S SPECIAL
Seemed to help polish last longer
Love it! My polish has stayed on for 6 days with washing dishes, laundry, swimming, etc.
I left a post 4 months ago stating that the brushes for the bonder and dehydrator split into 3s or 4s. To their credit, Londontown sent out new brushes. It seems to not be a brush issue because the new brushes did the same splitting. Maybe it's something with the chemical makeup in these 2 items, but it keeps happening. I just tried again on 1/15/2026, no go. No issues with the nail polish brushes so I don't get it but I just threw both items away to save myself the aggravation.

I left a review that seems to have disappeared. No matter, I will repost. This is the worst product I have ever purchased from Londontown. I bought this and the pre prep nail dehydrator. The dime store brushes split into 3 distinct parts that no amount of gentle applying can overcome. I requested a refund via customer service because I've spent hundreds on Londontown products and have never had an issue. I have not heard one word back from the 2 emails I sent requesting a refund. You just lost a loyal customer. I'll stick to Mooncat & Holo Taco.
