Re: 1/2" vs 3/4" plywood

Interior glue.

Not if you are using polyester.

Epoxy okay, but still a poor glue choice.

Re: FAIRING MIX IN NZ

You can use fast epoxy in small batches, too. I keep fast batches to 3 oz max.

Re: FAIRING MIX IN NZ

I use a 1:1:1 epoxy, cabosil, balloon mix for prefairing before Quikfair. I thicken it on a board with 50/50 dry ingredients until it does not slump when in a hump. Kite it in hard with a narrower trowel first. I like a 60 minute epoxy for it. Quikfair is a great product and feathers perfectly. But ...

I was using marine epoxy. Yes outside under a hangover. It was later in the evening so was thinking maybe from the temperature change.
How is the hangover?

I'd say you did good catching it.

Re: Marine epoxy

Amine is described as waxy. I have never encountered it and expect it will bite me in the rear someday.. I am well read on the subject is all. I am glad you caught it. Typically happens when working outside or with doors open, etc. Different epoxies, etc. The stuff I am using never blushes in my con...

Re: MF14 - Minnesota

I am surprised the glass would end so closely to the chine. It might be tricky to get an inch to lay down without peelply. Is the bottom a single glass? If it is doubled, then you would be better off using narrower glass and overlaping the center. Ate you using 50" glass or 38"? If 50 and the hull i...

Re: C19 - Major Structural Issues - Progress

One more link for doubters. Expanded polystyrene was removed from a home foundation barrier in Mn. The saturation rate of expanded foam was 18.9%. A cubic foot of foam weighs about ?5 pounds or less. 18% of a cubic foot of water is 11 pounds. They also removed extruded polystyrene. You can see, it, ...

http://www.owenscorning.com/NetworkShare/EIS/10018681-FOAMULAR-XPS-Performs-Better-EPS-Tech-Bulletin.pdf This has absorption rates for the OC products and compares xps to eps. X-extruded vs E-expanded. Expanded will gain water overtime and saturate. The percentages are misleading in the tds. If you ...
