I have recently purchased a UV gel kit and have been practicing. Would just like to say I have had no training at all so i'm just practicing on friends and don't know the technical terms for the application. I applied the nail extension and then put a coat on and cured under lamp, then built it up with clear builder and cured again then wiped off and top coated. I followed the instructions that came with the kit but two of the nails came off the day after. They felt really strong and secure. Could it be that i didn't cover the nail extension properly with UV gel or could it be i'm building it too thick? help would be greatly appreciated as the end result does look reasonably okay. Thank you in advance x
