Basepaste vs P-Tex: Which Ski Base Repair Should You Use?
Every East Coast skier finds a rock eventually. Shallow scratches and deep core shots need different fixes, and picking the wrong one is why so many home repairs fall out after a few runs.
The short answer
Light scratches: a P-Tex candle or just a good wax. Deep gouges and core shots: a two-part repair compound like Basepaste, or a shop base weld. Cracked edges or delamination: take it to a shop.
The three ways to fix a ski base
P-Tex candle
You light a stick of polyethylene and drip it into the gouge, then scrape it flat. It's cheap and fine for shallow scratches. The problem is that dripped P-Tex mostly sits in the gouge instead of bonding to it, so on deeper damage it tends to pop out.
Shop base weld
Shops use a base welder or extruder to melt repair material into the damage at a controlled temperature. It bonds much better than a candle and is a great repair, but it means a trip to the shop and waiting for your skis.
Two-part repair paste (Basepaste)
You mix two parts, press them into the gouge, let it cure and scrape it flat. Because it cures in place instead of being dripped in, it fills the whole gouge and grips it, which is what you want on a core shot.

How to fix a core shot at home
- Clean and dry. Remove wax and dirt with isopropyl alcohol and let it dry completely.
- Square up the edges. Trim ragged edges of the gouge with a utility knife or razor.
- Mask it (optional). Blue painter's tape around the gouge makes cleanup easier.
- Mix and apply. Mix Part A and Part B until the color is uniform, press it into the gouge and slightly overfill.
- Cure. Leave it overnight at room temperature.
- Scrape flush. Use a sharp base scraper to bring it flat with the base, then lightly sand or get a base grind to blend.
Black blends in on most bases. On a light-colored base, cut the gouge into a neat square or triangle before filling it and the repair looks clean and intentional.
FAQ
Is a two-part base repair compound stronger than P-Tex?
For deep gouges and core shots, yes. A P-Tex candle melts polyethylene into the gouge, and it doesn't really bond to the base, which is why candle repairs often pop out. A two-part compound like Basepaste cures in place and grips the damaged area, so it holds up better to impacts and flex.
Can I use P-Tex on a core shot?
You can, but it often fails. Melted P-Tex doesn't bond well to the exposed core or the edges of a deep gouge, so it can chip or pop out after a few runs.
How long does Basepaste take to cure?
It sets quickly, and reaches full strength in about 24 hours. Leave it overnight at room temperature before you scrape it flat and ski it.
When should I take my skis to a shop instead?
If an edge is cracked or pulling out, the ski is delaminating, or the base is damaged over a large area, take it to a shop. Base repair compounds fix the base, not structural damage.
