ski tuning guide:
base repair
Tools: Ptex candle, steel scraper, long-handled lighter, brake retainers (optional), metal baking sheet (optional)
| 1. Prepare skis | Install brake retainers (if repair is near brakes) |  |
| Place skis in vise, base-up | ||
| If you are working over a flammable surface, place an old metal baking sheet under the location of the repair to prevent drips. | ||
| Clean bases of visible grease or dirt around repair | Use citrus degreaser or detergent with rag; rinse off completely. | |
| 2. Light Ptex | Prepare work area. Set metal scraper across ski base, near first repair. |  |
|
Light Ptex. Hold in flame of long-handled lighter (not a match as shown) until it burns on its own (this take a minute or two). Hold candle and lighter over metal scraper to catch drips. When the Ptex starts to burn, the flame will be orange. The first drips from the candle are laden with soot, and should not be used on the ski. Let them drip onto the scraper. |
 |
|
| 3. Apply Ptex |
Once the Ptex candle burns with a blue flame, move it to the first repair. Hold it about 1/2 inch above the ski base and let the molten Ptex flow into the repair. Move the candle slowly along the length of the repair. Keep the metal scraper close in case of flare-ups, or to move the lit candle to other repairs. Do not breathe on the candle flame, or it will flare up. If a repair is particularly deep, and the first layer of Ptex does not fill it completely, let that layer cool and then add another layer until the depth is sufficient. |
 |
| Cool the Ptex to room temperature |  |
|
| 4. Scrape excess Ptex | Hold metal scraper at 45 degrees to the ski base, with a long edge on the base. Scrape in the direction indicated (scraping in the other direction may pry the Ptex out of the repair). Use medium pressure so that a thin layer of excess material is removed with each stroke. Use long strokes - across the full length of the repair. |  |
| Keep stroking until Ptex only remains in the repair, but is removed from the surrounding base area. For the final strokes, you can scrape in either direction. |  |
|
| 5. Finish | Hot wax skis |
