Sorry can anyone please tell me what grit files they are using to do acrylics? I was taught to use 100/180 - softer side to rough up natural nail before applying enhancements and rougher side to file acrylic after it is applied. Doing some research on here I have found that perhaps I am using to harsh of a grit. Can anyone advise me what grit they are using and for what procedures. Thanks Charlene.
