Liquid Polybase – Rigid Semi-Permanent Base for Extensions and Modeling (Medium Viscosity) TPO Free Liquid Polybase is a builder semi-permanent nail polish with an extremely strong structure and low flexibility (rigid). Due to its medium viscosity and post-polymerization hardness, it behaves similarly to a builder gel, allowing for small to medium extensions on templates, as well as apex formation. Being a rigid base, it perfectly supports filing for finishing the architecture, making it the ideal solution for strengthening very fragile natural nails. Solutions for Common Salon Challenges Broken corners / Need for extensions: Unlike classic rubber bases (which are too elastic to support an extension), Polybase has the necessary rigidity to extend the nail on a template (small/ medium extensions), saving the manicure without switching to a classic gel system. Thin, "paper-like" natural nails: Its reduced flexibility provides a hard "shield" over the natural nail, preventing bending and breaking from mechanical shocks. Difficult filing of gummy bases: Thanks to its strong polymer structure, Polybase does not clog the e-file and allows for precise filing, exactly like a hard gel, making it perfect for correcting architecture. Lifting of hard materials: By following the correct adhesion protocol (with a flexible base underneath), it prevents any form of lifting at the cuticle level. Main Characteristics Medium Viscosity: Leveling is controlled. It does not flow into the folds, giving the technician the necessary time to model the apex or the extension on the template. Hybrid Product (Strong Structure): Combines the speed of bottle application (specific to semi-permanent polishes) with the durability and resistance of a builder gel. Excellent Pigmentation: Formulated with high-quality cosmetic pigments, it evens out the nail bed and covers imperfections in a single modeling layer. Instructions for Use Because Liquid Polybase is a hard/rigid material, it requires a "shock absorber" between it and the natural nail to prevent lifting. Mechanical Preparation: Finely matte the nail and remove dust. Chemical Preparation: Apply Nail Prep (dehydrator) and Bonder (acid-free primer). Allow to air dry. Adhesion Layer (Critical Step): Apply a transparent base coat (we recommend Liquid Base or Rubber Base Clear), brushed very thin and massaged into the nail plate. Polymerize completely. Modeling / Extension: Mount the template (if applicable) and create the extension or build the apex using Liquid Polybase. Finishing: Due to its structure, the material can be degreased and filed to achieve the perfect shape. Pro Tip: Because Polybase creates a very tight polymer network (to offer that strong structure), it releases heat during polymerization (heat spike), especially when applied in a modeling layer (apex). Use the Low Heat Mode function of your lamp or instruct the client to remove her hand for 3-5 seconds at the first signs of heating, then reintroduce.
