You can apply the primer after polishing. If it is a crystal nail, apply a desiccant before applying the primer. If you want to engrave the nail, use a sanding strip and then a sponge.
Try to keep less water and detergent after the manicure. This is because if the nail is stained with water or detergent afterwards, it will easily cause the nail to fall off. So, if you need it, you should wear rubber gloves or thin leather gloves, so that the nails will last longer.
