Segundo a Mavala...

... estes são os procedimentos correctos para aplicação de verniz:

1. Test consistency of polish on nail tip before beginning.
2. Begin by applying polish down to the centre of the nail in one stroke, from base to tip, leaving a small space between polish and cuticle.
3. Apply polish to cuticle base, stopping just short of the cuticle.
4. Lift brush and stroke one side of nail from base to the tip, avoiding the cuticle.
5. Stroke other side of nail from base to tip.
