It depends on what kind of wax you use. There is liquid, paste, and hot wax. Liquid wax you just applie evenly, buff it over board, take off extra and go, but I like to let it sit for 5-7 min to soke in. Paste wax you applie on board and buff it like the liquid wax. Hot wax is hard wax you heat up and put on your board (I have never done it, make sure you have some show you how to before you try it!) It isnt hard, you will not mess up you base as long as you spread it evenly and there is no bald spots.
