Once they’ve fixed any base issues and have sharpened your edges, a ski technician will then base grind your skis. Base grinding is when you run the bottom of the ski through a stone grinder, which helps to further flatten and smoothen the ski’s P-tex (polyethylene base material used on skis and snowboards) base. Doing this helps to bring back some of the “slide” in your ski so it doesn’t feel “sticky.” The tech will then finish with a coating of ski wax, which serves to create less friction between the ski and the snow, allowing you to effortlessly slide downhill. It is always nice to start your season fresh by tuning your skis before your first day out. And if you want to get consistently high performance out of your skis, consider getting your skis tuned every two to four weeks.
Pro Tip: Get to know your local ski shop. They love making friends and understand that most people are skiing on a budget. A 6-pack of beer can go a long way.
The first and easiest way to fix a core shot, or any issue with your skis, is to bring your ski to a local ski shop. Ski shops have a dedicated ski tech team that deals with this all the time—it’s literally their job. They will fill the hole with P-tex, a strong adhesive that is used to create bulletproof vests. The ski technician will expose the rubbery P-tex to a flame to melt it, and then drip the liquid into the core shot, filling the hole and protecting the core from the elements. Once they’ve smoothed out any excess P-tex, they will then wax the ski. If you’re looking to save even more breakfast burrito money, you can purchase P-tex and apply it yourself.

P-tex isn’t a forever fix, though. It can last anywhere from the rest of the season to your next time skiing. The closer your core shot is to the edge of the ski, the more likely the P-tex can be ripped out. Make sure to routinely inspect the repaired areas (as well as the entirety of the ski) and re-fix the base of your ski as soon as any new or recurring damages occur.
However, skin savers can’t prevent the inevitable. Over time, skin glue will naturally lose its adhesiveness. When it finally begins to go, you will notice that your skins are far too easy to rip off at the top of a ski line. They may even begin to fall off the ski on the uphill. When this happens, it’s time to revitalize your skin glue. You can find purchase skin glue at your local backcountry ski shop or online here: (link) as well as watch tutorials on how to apply it.
