It is important to wait until the varnish is completely dry before applying a new coat, otherwise you will end up with an uneven finish. If you apply the second coat too soon, the first layer of varnish will still be wet and won’t have had enough time to cure properly. This can cause wrinkling or bubbling of the varnish which ruins the smoothness of your paint job.
