Wet a cotton ball with a non-acetone nail polish remover. Wipe each nail several times to remove any polish. Do not use an acetone nail polish remover. Nail polish removers containing acetone will damage your acrylic nail. Because French manicured acrylic nails are created with white tips, this will not remove any of the color.
Dip the nail brush into the acrylic liquid and place it into the acrylic powder until a soft ball forms on the tip of the brush. Pat this acrylic gel into the fill-in area, the area between your cuticle and acrylic nail where natural growth has occurred. Dip the brush into the acrylic liquid again and smooth out the fill-in area, working it across the acrylic nail and white tip. Repeat this process until the entire nail area is covered in an even layer. Avoid adding too much wet acrylic to the existing artificial nail or it will become too thick.
Allow the new acrylic to dry for a minimum of 20 minutes. Work the emory board across each area where the new acrylic was placed, beginning on the right and moving across to the left. Work your way up to French manicured acrylic nail until you create an even, smooth surface. Never make back and forth motions across your nails or you risk damaging both your natural and acrylic nail.
Apply two layers of a clear top coat to lock in your French manicured nail. Allow each layer to completely dry before adding the second layer. Let the second top coat layer dry.
