A method of coating human nails with a polymer film. The method comprises steps of: (a) applying to the human nails a composition comprising:
(i) a first polymer binder having Mw greater than 20,000 and a Tg less than 70°C;
(ii) a second polymer binder having Mw less than 15,000 and a Tg greater than 90°C; and (iii) water; wherein the composition contains less than 10% of organic solvents; and (b) allowing the composition to dry until the polymer film has formed.
