Guy,

Here is what the finished rear deck/transom area looked like on my brother’s FS 19 before the non skid was applied:

That looks very nice that way Jordy. After seeing yours I like them equally. This is one of many finishing touches I’ll run by Lyn. She as (well me) is focused on this build being comfortable and “not looking home made”. I used your build thread with her as a selling point. Thanks for reposting.

Unrelated except that it’s why I’ve slowed down on the build, the spike buck (center right behind fork in tree trunks) laid here for 38 minutes after chasing the doe around for 2 hrs. :doh: maybe not unrelated, even beasts of the woods are concerned about impressing their better halves.

Epoxy cure temp question????

Post by GuyP » Fri Nov 15, 2019 8:13 am

My FS19 build is in a detached single garage. Looking at the epoxy cure time/temp charts, I believe I’m ok as long as I maintain at least 40 degrees Fahrenheit while curing (2 to 3 days). I won’t be able to heat the entire space due to limited power to the building. I can although cover with tarps and keep the temp above 40 with small space heaters since I’m working on the interior of the boat. Sound ok?

Guy, do a few tests and lets get the results before you do something major!! Jeff

I have never had a problem with the epoxy not curing during the winter here in Georgia, it just took longer. It definitely took longer to get hard enough to sand though. But it also gave me more working time compared to the summer when I had to race to beat the epoxy from kicking too fast. I much preferred to work on the boat projects during the cooler months.

Keeping your jugs of epoxy in a warm place will make a big difference on the viscosity as well as speed up the curing time. This can really make a difference when trying to wet out fiberglass cloth and tape.

Jeff: I did some interior taping with outside temps in high 30’s and the fast hardener. Little space heater must have done the job as all has set up nicely and is sandable. I guess I’ll use that as my test! I’m sure I can keep temp at least 50. Jordy is a little south of me but it still gets pretty cold in Brunswick.

Jordy: on previous lapstrake epoxy glued boats I’m sure I worked in mild winter with those. I like the longer working time too.

Thanks fellas

Nice thing about epoxy is that if it's too cold to finish curing, it will cure once the temp rises again. It can be hard to work with cold epoxy due to the viscosity though. If you work through the winter at the lower end of the temp range, I would recommend a "post cure" before you fair or paint. Use a heater on a warm day with your tarps to get the temp up to over 100, exact temp depends on the epoxy. This will make sure everything is fully cured before you paint, or after you are all done and have it out in the sun it may finish curing and you may see print through of what's under the paint.

I'd also recommend one of the forced air propane heaters that run off a BBQ tank. They will get the place nice and hot when needed on just the electricity of a fan. Do get a CO detector if you go that route though.

My first sna-foo. “Graduated” mix cup ml markings were sorely off (NOT purchased from BBC). Instead of a 2 to 1 resin/fast hardener mix, the inaccurate scale resulted in 2 to 1 1/2. Cloth was stiffening up quickly and foam roller started SMOKING. I cut out the section of cloth I had just applied and had to pull hard to get it off the hull. It was rock hard stiff in 30 minutes. I resumed using the resin pumps I’d been using successfully since day one and all was well. Red circle is where I had removed the quickly stiffening glass. I’m hoping the mis-mixed resin will sand off in a day or so.
