Rub the bottle between your hands to warm the nail polish for about 25 30 seconds

This helps to mix up the contents of the bottle, stirring up any color that has settled on the bottom. Dont shake it rolling the bottle instead will prevent bubbles from forming in the polish and keep your nails smooth. Paint one strip down the middle, then one either side of that. Reload the brush with each stroke if you must. It is better to go thinner; you can always apply another coat.
