Clear Builder Gel (formerly known as Builder Gel XL) is a thick, protective polish that strengthens nails by creating a stronger nail foundation. The thicker viscosity of the gel will prevent breakages and smooth nail ridges while promoting growth. Our Clear Builder Gel requires one thin layer of our 2in1 Base Coat & Extension Adhesive before application. Once cured, Coloured Builder Gel has a tacky surface, which must be sealed with our No Wipe Top Coat OR One Step Gel to achieve a smooth, glossy, and long-lasting finish.
