Why is my PTEX cracking?
Overfilling a deep hole in one hit can cause the ptex to crack. Once the ptex is cool to the touch (5-10 min), you can begin scraping back. Holding your metal scraper at an angle, start scraping from the front to the back of the ski. Vary the direction of each pass, so that you're removing material evenly.
What temperature does PTEX melt?
CAUTION! A P-Tex candle burns very hot (>970 F); Severe burns can result if dripped on skin. Ventilate room if you recently used fluoro waxes. Hold the candle close to the base to reduce carbon (black) formation from the burning process (see important notes at the bottom of the page).
What happens if you ski on a core shot?
Core Shots. A core shot is when the core of the ski is exposed to the elements (water, moisture, snow etc..) instead of being protected. Moisture getting into the core of the ski is bad, that moisture can freeze too, so let's talk about how to fix it. Core shots are the most tricky and require the most work.
How many times can you base grind a snowboard?
A full ski base grind is recommended after the first 5-8 days on a newly purchased pair of skis to give it time for the epoxy to settle. This process actually planes a small layer of base off the ski and can therefore only be done up to six times over the life of the ski.

Learn how to p-tex repair your skis to ensure you'll never miss a day on the mountain
Learning how to p-tex repair skis is an essential task as, although we always try to avoid them, at some point in your ski career you’ll no doubt hit a shark that will leave a gaping hole in the base of your best skis.
What You Need For A P-Tex Repair
If you are doing this indoors make sure there is good ventilation and lay down large old sheets to protect valuable floors or surfaces
Step One
Assess the damage and clean the area. If the base is just scratched and you can’t see the core then a p-tex candle is all you need. Use your metal scraper or a sharp blade to clean away any loose sections or scraps of base hanging off. You want to be melting the p-tex into a clean scratch.
Step Two
Place the lighter to the p-tex candle. Careful not to drip or drop it on your skin or anything else precious. You want to have it burning gently with a small blue flame. The flame may turn orange, but be aware not to smoke the room out!
Step Three
Leave the p-tex repair for a few minutes to cool completely. With the metal scraper, holding it at an angle, scrape the p-tex to remove the excess and leave a flat base. Take your time to get it as flat as possible, with a bit of practice you will do this in one clean stroke.

What do I use to repair my base?
P-tex is used to repair your base. It’s the same material your base is made from and it often comes in a thin candle stick form. The p-tex is melted into any gouges or scratches in your snowboard to fill in gaps and make your base smooth again.
Will the repair be as strong as the original?
Nope, it’s a make do fix. It will generally fix any small scratches, but you’ll find that large gouges or scrapes can be a pain to repair because the p-tex keeps falling out and exposing the hole again.
Does it matter if my base is Sintered or Extruded?
Not really. If you’re not familiar with base materials, ski and snowboard bases are made up of 2 types of different types of p-tex, either sintered or extruded. Without getting technical, sintered bases are found on higher end gear and extruded bases are found on cheaper models.
How to get adhesion between repair and hull?
Improved results in terms of getting adhesion between repair and hull are obtained by first sanding the hull surface to create a texture and then “flaming” the hull in the area to be repaired. Flaming consists of passing a torch or open flame back and forth over the hull, keeping the flame moving at all times and removing it before the material shows any sign of melting. For best results you should be prepared to proceed with the repair immediately after flaming the surface.
Where should patch layers be placed on a boat?
All patch layers should be placed on the interior of the hull and the exterior of the crack should be covered by the polyethylene drip method described earlier. Placing patch layers on the exterior of the hull is just asking for them to be peeled off by encountering sand bars, gravel bars or other obstructions on the water.
How to keep a canoe from cracking?

How to get polyethylene to a liquid state?
Polyethylene has a low melting point and a lighter is usually sufficient to kick the material to a liquid state. Simply drip the new material over the top of the crack and for about ¼” beyond each end of the crack. Then repeat on the opposite side of the hull.

Can you repair a crack in a canoe hull?
If the unlikely occurs and you have an actual crack in the hull, it’s a different story. Depending on location and extent of the crack, it may or may not be repairable. It is very difficult to perform a structural repair on polyethylene and if the crack is extensive or in a critical location, it may pose a hazard to continue to use the canoe and it may be time to take it to the recyclers. The best way to determine whether such an injury is fatal is to contact customer service and email pictures to them. They can advise you of your options.
