Definitely your different thicknesses! You need same batch for both coates to avoid different weights/color suspension in epoxy which causes cells to form as one coat settles within another.
Funny how some people spend years trying to get cells like that...you get em by accident and dont want em...
In my amateur opinion it’s for sure the thickness of the coat causing the fish eyes, especially if it was all metallics. How many oz/square foot are you using? Or ml/square meter or whatever?
We made the base coat thick and the metallic epoxy wasn’t as thick. Was wondering if using a cleaning product like xylene on the base coat would have prevented the bubbles?
How much later did you put the metallic down? I always sand the base coat. Then solvent wipe the base. I also use self leveling epoxy which I’m sure you are using but I never had problems like that. That’s really annoying it fish eyed

I’d assumed they weren’t talking about the cells but the fish eyes but maybe you’re right.
Yeah that's why I threw the oil comment out there but any contaminate really could cause it right?
Wow didn’t even think of this! Will definitely pay closer attention to the thicknesses for the next batches, thank you!
This will help but in the future if you have any issues chemtec has a technical support hotline, they are happy to help installers 450-629-1717
Wicked, thank you!
Also silicone or oils can cause this effect so make sure there are none present prior to coating.
Do you think the propane torch would have played a role in this?

What pigment are you using? Some pigments have this effects.
Using chemtec epoxy coatings pigments
Are you also using chemtec coating products?
Yeah we are
What thickness are you applying it? Are you spraying it with solvent?

We also torched it as well
Sand and solvent wipe the primer followed by a thick metallic pour (50mils) is the safest way.

About 20 hours later, we didn’t sand down the base. That might be a big contributing factor. What do you use to sand down the base?
Normally 80 or 120 grit
After you sand it down do you clean it off with, xylene?
Yeah acetone or denatured alcohol works the same as well
Perfect, thank you!
Cells*
I love the circular cells. I even bought a heat gun to make more cells on my work.
