Nes999's 1,000 Gallon Plywood Build Mark Two

... Sweetwater is a solvent based epoxy paint so there is not only the endothermic (heat producing) reaction but also an evaporative process as the solvents offgass. With a 100% solids system like West Systems there is only the endothermic reaction and no evaporation.

Sorry, that should read exothermic in both cases, not endothermic.

im well versed in epoxy. ive been working wth different types, on a regular basis, since about the age of 15. but sweetwater is not exothermic. trust me 54% percent of my body is blue right now it did not heat up like epoxies always do. it reacted much more like a paint.

The degree of exothermic reaction varies among 2k catalyzed finishes. But I agree that solvent based epoxy paints don't heat up like some other resin systems.

Regardless, I just wanted to point out why the solvent based epoxy paints should be applied fairly thin.

Yeah, i wholy admit that was my screw up. This product is amazing so far ive left it outside in the cold for 30 somthing hours and it didnt harden. i also found a trick to reuseing brushes and rollers. Put them in a plasic baggie. it keeps all the air out and they wont harden.




For my over head filter i might try to spray it, just to see what happens. key word might.

The stuff i work with will melt the bottom out of a 5 gallon bucket. so i guess im just used to that.

i have today off so once i muster some will i am going to insulate.

I've put unused portions in refridgerator and I've done the plastic wrap method. But I've never then used that leftover on a fish tank as I heard it sometimes won' cross link as well. Instead I would use it on the upper (non water holding) part of paludaria. Always made for a tough and very scrubbable finish but I never tested the stored overnight leftovers on a water holding tank. Fortunately I always had enough projects going on that I could get away with this.

I've never sprayed any sort of post catalyzed resin as I've heard the learning curve is pretty steep. But with that said the solvent based epoxy paints are supposed to be the easiest by far.

Let us know how it goes. I'm hoping to read your entire thread something this weekend if I have time.

Great work! Cant wait to see the finish project.
