I sent my snowboard to the shop to get the base repaired. However my base is sintered and I didnt say anything to them about that or anything and im just curious if like theres supposed to be a different method to repairing a sintered base? Why is it always considered hard to repair a sintered?
Sintered is the most common base type and is better performing than Extruded bases. A rental board may be Extruded. I cannot remember if there are different tuning styles for the different base types. I have always had Sintered and have tuned for that tho. I imagine the repair shop would assume that as well.
from what i learned, sintered can not be added to easily. the guy that works on my board said they'll grind the base down to get gashes out, but if its really bad, they had to add another “sheet” because you cant add spots like you can with p-tex. sintered is harder to put huge gashes in than extruded, but when you put a very very deep one, the board is pretty much considered trash, because it costs too much to grind it that far down and build it back up again. thats why most people (other than pros, their boards are free) resist hitting jibs with a deck with sintered bases.of course this is word of mouth, i take extreme care of my sintered board for this reason alone 😉
oh and how they know…. my shop looks it up, and if they cant figure it out, they consider it extruded…so you want to tell him just in case. p-tex will stick to a sintered base long enough to look pretty, but once a radical temperature change..ie snow… hits it, it will pop back off.
Travz//, sound right but I think you have them reversed. This is what I always believed:
Sintered is the most popular kind. Is is softer and more porous and easier to repair but also easier to scratch.
Extruded is mainly found on rental boards and some park specific boards especially for it’s durability. Harder surface, will not take wax as well and therefore can be slower. Once trashed very hard to repair.
sintered is harder to put huge gashes in than extruded, but when you put a very very deep one, the board is pretty much considered trash, because it costs too much to grind it that far down and build it back up again.
That almost made me cry travz. (jk kinda) I put a uber deap gash in mineFrostys post was a nice relief though. lol
frosty is correct by all information i can find as well. for some reason i was told never to ptex mygrudge because of the sintered base, it has to be ground. i dont know why, but its the info ivestuck to. i dont now if forum bases are made a bit differently, but im afraid to try…so this is where i get confused.i was told never to p-tex my grudge which is sintered.but i can p-tex the crap out of my manual and recon, which arep-tex 4000 bases.this is the info i got from forum, so i dont know what to think. i know p-tex is another manufacturing process of sintered, i knew that before thewikipedia guide, but since sintered is the melting down process of p-tex pellets,and p-tex bases are compressed sheets of p-tex, i dont know what to do about scratchesin either now. :(so seriously now im confused and worried so i need an explanation lol
Ok I got it back today. Here’s how the p tex went:
. They definitely filled it in good and every thing but it doesn’t look soo great. Like my snowboard has stitches. O well. And there’s a lil black line in this pick right above the hand. Anyone know why this might be. They rewaxed the entire thing btw. 
Sry the pics aren’t the best, I took em with my phonehttps://frostyrider.com/wp-content/uploads/2023/01/scratch-on-snowboard-base-36_15_01_09_5_49_58.jpg
Yeah, really hard to tell with the phone camera. If you get just about any digital camera with a flash onto that it will be more distinct.
Sorry frosty I’m just too lazy. I outlined it tho here. Kinda right in the center of that red square is a little blackness. I was just curious if anyone’s seen anything like that after a waxing. No big
No biggie. They might have just run a board with a black base over the belt grinder right before yours. Might just be rub-off from that that got cooked in.
