Each coat must dry thoroughly before applying another coat. More than two coats should be baked on, air drying isn't hot enough.
The newer method is gel polish activated by UV. I'm not a professional, but I've always done my own, a heat lamp or hot blow dryer can do the trick. Past two layers will be prone to disaster no matter how still you sit.
omfg! this annoys me sooooo much! gosh I cant stand non painted nails but putting it on is annoying!
It takes longer time for it to dry
cause it gets thick
Science...I don't know.
