For the last step, apply a base coat to the entire nail. Immediately dip it into the powder and remove any excess. We recommend applying 2 coats of build powder and 2-3 coats of color powder. This method is more effective than applying 4 coats of color alone. Build powder does not contain any added pigments or glitters, making it stronger. It also hardens faster when activated, helping you avoid gumminess inside if you file too early.
