1. Always Keep Your Board Waxed.
The base of your snowboard is made up of a plastic material called P-tex. It's a naturally porous material (especially sintered bases) , and waxing it fills those pores with moisture, making your board faster. You can never have too much wax. I like to wax my board at least every few weeks, sometimes more.
2. Keep Your Edges Clean
When your edges are rough, they add unwanted friction when carving. It's pretty easy to keep them clean and smooth using a small file, or an edge stone. For larger burs, having your edges tuned by a pro can be helpful.
3. Fix Gouges and Core Shots
Everyone bumps into a rock at some point or another. When you do, it's important to repair the base of your board, especially if any of the wood core is exposed. If you leave a core shot open, your wood core will soak up water and eventually break. Its pretty easy and inexpensive to use a P-tex drip candle to fill in deep gashes in your base. If the gash is up against the edge of your board, it's smart to take the board to a pro. If your board has a lot of small gouges and scrapes, take it to your local shop for a base-grind and give your board fresh start.
If you're not into waxing and tuning your own stick, bring it in to MiloSport in Orem for a full tune-up by Ty the gear guru. After all, there's nothing worse than a sticky snowboard.
