Welcome to the Vu Nail Systems Gel-ato Bottled Builder Hybrid Training Course. Bottled builder gels offer nail technicians a convenient way to create structured natural nail overlays and, where the formulation permits, short extensions. Although many bottled builders look similar, their properties can differ significantly. Viscosity, flexibility, adhesion, curing requirements and removal methods all depend on the individual formulation. This course develops your understanding of bottled builder gels and prepares you for supervised practical training using the Vu Nail Systems approach. Our practical training focuses on: Natural nail overlays. Short extensions using traditional nail tips. Application over a suitable standard base coat. Controlled product placement and structure. Filing and refining the cured enhancement. Gel colour, nail art and finishing. Infills, maintenance and safe product reduction. For longer enhancements, the Vu Nail Systems training range includes SHINE Hard Gel, which is covered in a separate course. Important: This theory manual does not qualify learners to attempt unfamiliar practical techniques independently. Practical skills must be demonstrated, supervised and assessed.
