Summary: Top coat nail polish protects your nail art designs from being chipped. Learn how to apply the top coat polish in this free nail art video from a professional nail technician.
"After you've completed your nail art design, in this case, the flamingo, you're going to want to allow at least two minutes to dry. Then you're going to start putting on your base coat, or, excuse me, your top coat. When you put on your top coat, you want to go down the entire length of the nail and you also want to stripe it across the free edge, the bottom of the free edge. Just to give it a little extra protection. If you apply the top coat before you've let the nail art design dry completely, it will smear and smudge the nail art, and you will have to take everything off and start all over again. We only did four nails for the flamingo, but usually you will do all ten, and in that case you will put top coat on all ten nails. Even though we didn't do the design on the other nails, you're still going to want to put a top coat just to give it the shiny glass-like finish. And it's protection for the color. When you've finished the last nail, you just want to double check, make sure that you haven't gotten any polish, whether it be the striping brush polish, the nail polish or anything on the cuticle or the actual skin of the finger. If so, take your brush that you use for your French manicure, go back, dip it in the acetone and then just clean up the side walls of the nail. And that is how you apply the top coat to your flamingo design."
