Default Another base repair question

I'm trying to repair a small core shot with some of this stuff.
P-TEX BASE MATERIAL

I sanded the bottom out a little bit then put some marine epoxy in and clamped the small ptex piece for 24 hours. Today I went to wax the board and when I was done i noticed the bottom part of the repair was already coming loose. I'm guessing I'll just have to pop the whole thing out and try again but I'm wondering if I should make the bottom section of the gouge a little wider so the repair piece is in contact with more epoxy since its so skinny and shallow.




heres some pics (they didn't have black material)

I fixed a few gouges with the P-Tex candels on my rome GR (extruded base) with good sucess.. Not sure how it'd work on a core shot on a sintered base of the Flow Infinite.. I'd give that a go maybe? I'm tuned in to see what others say

Unfortunately I don't have any candles and my shops are too far away for me to go pick one up before I hope to ride again. Tognar recommended this material for sintered bases but all the info online was for candles so i kinda had to wing it...hoping someone on here has experience

why would you clamp ptex? ...ur supposed to light it up and let it flow

the epoxy is to seal up exposed core/wood...let it fully cure and then flow in the ptex

Because it's not that type of ptex, its a piece of base material. you don't light it and drip it like a candle

i was following the directions from tognar


Quote:
First, cut and peel out the damaged base material using with a base template and repair knife.
then cut a new patch from these p-tex sheets (rough side down)
glue into place on the ski or snowboard base with epoxy.
Clamp the patch firmly (not overly tight or the epoxy will be squeezed out) using small c-clamps and flat wood or metal plates to distribute pressure evenly over the patch.
Allow adequate time for the epoxy to dry.
After removing clamps and plates, re-prep and hot wax the patched base area as usual.

it kind of looks like you just have a gouge without any exposure to the core...if that is the case...scrape out the epoxy and properly ptex. if you don't have it...go early to the hill...if they have a good shop they can do the repair in a few minutes

idk...does not look to be big enough for a patch...just de-wax and reflow with some ptex

If you have to use that instead of the candle, try widening out the area. Also did you use anything to remove wax from the area before hand? The wound should be square instead of a V for that repair to work best.

Even mineral spirits should remove the wax from the surrounding area... You mentioned sanding but you didn't say anything about removing the sanded crap from the area. Sand if need be, wire brush, but you'll have to use some sort of solvent to give the epoxy something to bond to.

I lightly sanded the area to remove any wax or crap. I'll have to do it again now to remove the epoxy from the failed patch. I did square it off so I'll try it again with a wider surface area.


Thanks for the advice
