A couple of questions about EkoPoxy. I would like to mix by weight, do you have the ratios for doing that? The calendar has been moving quicker than I have, so having the recommended temperature for spraying will be hard to do. What will happen if I am at 50-55F ? I am not spraying surfaces, only framework if that matters.

I see this is under the primers. I didn’t find it necessary for the primers but I did for the poly top coats. Stewarts sells the dupont M50 viscosity cup online. I found it useful as a spot check the viscosity. When you use the mix by weight the water calc takes a couple of trys to get just right or what works or your setup. Once you get the ratio that works well write it down for each color. I found that each color was a little different. But this was before Eko-poly premium which I under stand is a little more forgiving.jamesmangoldParticipantJanuary 22, 2019 at 3:01 pmPost count: 1
Is the Viscosity cup essential? If so where can I purchase one?jason gerardModeratorJanuary 22, 2019 at 3:01 pmPost count: 209
Directions are on the can to mix by weight… It’s not critical so I just divide part A by 5 and mix it good for a few minutes before thinning to what ever works with the gun you’re painting with. If it’s too thick and you can’t seem to get it to atomize just add more water. It normally takes about the same amount of water as catalyst but no more than that. The epoxy is supposed to be thicker and needs to be shot through a 1.4-1.6 mm tip
Keep the paint and primer above 60 degrees before mixing and yes You can spray in the 55 deg temps.
Practice before painting real airplane parts so you don’t have to sand and re-prime/paint
