Noodle, I've got gas?

I’m 90% done with my epoxy. This weekend I decided to put fcs fins in it because I already had the plugs, might as well use them. Anyway, after marking my fin positions, I used the ice pick tool to set my spot for the hole saw. When I punctured the glass I heard a hissing sound. The board was releasing gas. It did it on both sides of the stringer. Have you ever had this happen? The board is not blistered anywhere, and the sanding layer did finally flow out. All in all it looks good, I just don’t want it to blister down the road. Do you ever put valves in your boards? I have seen them in surftech/bic type epoxys. Also what is up with the tiny bubbles that float out in the air when you stir the resin with the hardner? I felt like Lawrence Welk.

Noodle, I have heard that epoxy board do have a tendancy to gas. Greg Mungal mentioned he wanted us to make a pressure release valves for epoxy board applications. But, then I have not heard from Greg in quite some time.

Mike and Tom, If you glassed the top in cold weather that could cause some pressure buildup in warm weather. You’ve stumped me on natually gassing epoxy skin. I’ve never heard of it. I’ve read testimony from people who have glassed without spackling. When you glass directly onto EPS, it wicks in epoxy and builds up pressure. I’ve also read testimony from people who failed to dry out their spackle thoroughly. That can cause big pressure. After I glassed the bottom of one epoxy board, my glass soaked up a little rain water. I didn’t realize it. When I glassed the deck, these huge bubbles kept blowing up as the epoxy cured. Moisture is a huge gas factor in epoxy cures. I like the valve idea. If you glassed a valve into each foam compartment it could relieve gas caused by anything. -Noodle
