Step 25Repair P-Tex snowboard or ski bases
Next time you see a ski with the p-tex bottom coming off it, pull it the rest of the way off and use it to repair your good ones. P-tex is a porous polyethylene that absorbs wax and has very low friction with snow. You can buy "candles" made from this stuff for base repair, but the scrap stuff works too.
So I lit a strip of scrap p-tex on fire and dripped it into the holes until they were full. Then I filed and sanded it flat. Then I waxed it. Then I went snowboarding.

Top tip from an ex ski-tech: Get a steel scraper, about the size of a credit card, light your polymer filler and hold the steel closely beneath the flame until the flame burns cleaner. This will mean the flame will be blue because you are cutting off some of the oxygen from underneath and reducing the amount of black soot created when that flame is large and yellow. Now the molten polymer will be more like a clear resin. Slowly and carefully lower your flame to the base of your ski or snowboard and then remove the steel so the base is now cutting off oxygen from below and the flame is hot and blue. Now when you fill your scrapes your repair will be stronger and less brittle as it was when the polymer was mixed with soot. Finish the repair as described before. Enjoy the slopes.
