if it's a new board and no scratches or heavy wear, you probably don't need a base grind. i guess the structure might help you hold some extra wax on there, but i really think it is not necessary, and you should try a base cleaner first.
it's super easy: get a bottle of some kind of citrus snowboard base cleaner - i'm sure you can find a cheap one online. get a shitty towel and apply it to the board and take all that shit off. then dry it with a clean towel and let it air dry for a while. after it's completely dry, give it a good hot wax. you'll be hauling ass next time.
