I have that problem when I don't let the 1st coat dry. I use a base coat (Orly Bonder), then 2 coats of Sinful polishes (allowing time between 1st and 2nd coat), then I finish with a top coat (I use Poshe) while the 2nd coat is still sticky. After that, I take a bowl and fill it up with cold water and let my hands sit there for about a minute. I can even go to sleep without waking up with sheet prints on my nails. Also, if your Sinful polish is too thick, consider a nail polish thinner (OPI makes a good one and it lasts forever since you only need a few drops). Good luck!
