The Nitro 2-in-1 Builder Gel Brush features both a professional oval brush and a precision liner, each protected with secure caps for safe storage after every use. Designed for durability and effortless application, it ensures smooth, controlled, and reliable performance.

Step 1: Prep
Perform a thorough dry manicure. Gently push back the cuticles, remove all non-living tissue from the nail plate, and lightly etch the surface using a 180–240 grit file. Remove all dust, then apply a dehydrator followed by an acid-free primer. Allow the primer to fully air dry before proceeding.

Step 2: Apply
Apply a thin slip layer of Nitro's Builder in a Jar without curing. Float a bead of gel to build structure, keeping the cuticle area thin and placing the apex in the stress area. Turn the finger upside down briefly if needed to help the gel self-level. Cure for 60 seconds in LED or 120 seconds in UV.

Step 3: Refine
After curing, remove the inhibition layer and refine the shape using a hand file or e-file. Ensure the structure is balanced and smooth before removing all dust.

Step 4: Finish
Apply gel color and top coat, or apply top coat alone for a natural finish. Cure according to the top coat instructions.

Maintenance: Rebalance every 2–3 weeks by debulking and rebuilding the apex.
Removal: File off only. Hard gel does not soak in acetone.
