Q: I just got a new 6’2” and I’m dying to ride it. But how long should I wait after it comes back from the glasser? Is letting a board “cure” a myth?

A: That all depends on your perspective, and what you consider to be a myth. Like any other chemical reaction, when fiberglass resin cures it takes place over a certain period of time. But just how long that takes is the part that’s up for debate—and dependant on a wide array of factors. Certain manufacturers will go so far as to put a “do not ride before” date on their boards to mitigate any negative affects from premature shredding. But if you’re looking for a good rule of thumb, something that’s applicable for any recently glassed board, it seems like a few days should be good enough. “I am not really a chemistry expert,” says …Lost’s Matt Biolos, “but the most educated people I’ve talked to say the majority of polyurethane resins are fully hardened within 72 hours. Epoxies are varied, but in general, if heat cured, they’re ready to go right out of the oven.”

    Hey, I’m also Materials Engineer besides a surfer and in a few experimental research I’ve made with polyester resin and fiber glass, the best results of the composite mechanical strength were obtained after two weeks of cure. After that, it became constant. But it depends on how much you wan’t to surf with your new board though…

    Off the subject but I have a Question? I’ve surfed Salt Creek in CA, for the last 10 years. I’m living in the desert right now but try and get out there as much as possible; seems like more then when I lived there. I see pros there and I always want to say whats up or talk about the waves with them or just simply smile and have them say hey hi back but it never happens. I’ve raced dirt bikes, bmx, downhill and have competed in sk8 contests and it seems like most pros have a grudge on people that are just out there to have a good time. What’s the deal? Im always down to help someone in a sport that I excel in, It’s not like Im some dude taking all the good waves.
