Brush-on gels usually have a __________ viscosity.

• A. Thick
• B. Thin
• C. Medium
• D. Runny

Answer: (A)

Viscosity describes how thick a gel is and how easily it flows. Brush-on gels are meant to be applied with a brush and to stay where you place them, so they need enough body to hold their shape as you work. A thick viscosity gives you precise control, helps prevent the gel from sliding toward the cuticle or sides, and supports building a strong apex during curing. If the gel were thin or runny, it would spread where you don’t want it, flood the cuticle and sidewalls, and require extra cleanup and multiple layers to achieve the desired shape. While other gel products used for glazes or smooth overlays may be thinner, brush-on gels are typically thick to enable proper shaping, control, and structural strength.
