i have two space heaters in the tank.
i honestly could care less about the flaws since this tank is for me and now one else. but the reason this came abou is the glass will sit on a 2 by 4 and the edges were rounded off and i didnt bondo them. so i tried to fill it and it leaked all over the floor. just waiting for 12 hours for it to dries is a killer. my basement was colder then 75 for most of it.
i left he gallon and a half outside so maybe i can use it tomarrothe w if im lucky. sweet water please dont harden outside.
Garhog mentioned epoxy curing with heat and that thicker dries faster. Just wanted to clarify that 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.
So in most cases it is better to apply solvent based epoxy paints in thinner coats than thicker and they (thin coats) will cure much faster.
I think the recommended wet film thickness for Sweetwater is 4 mils. But don't trust me on this, double check yourself.
For reference, a 4 mil wet film thickness on a perfectly smooth surface the size of a sheet of plywood is equal to about a tenth of a gallon. First coats on bare plywood would require a lot more than this since the solvents carry the solids so far into the pores of the wood.
