If it’s regular Zinsser and not the Seal Coat which is dewaxed, that’s normal at lower temperatures due to the wax. I just checked a can that’s in my garage at 60º and it looks the same.

Your picture looks more like their primer/stain blocker line after sitting for a very long time and allowed to separate…...

I have never had their shellac do that when stored out in my shop.

You said it was Bullseye, which is not dewaxed. Wax would be my guess as well. If it was cold, letting it warm up might redissolve them (if they are wax), or strain it through a filter.

thanks guys, that makes a lot of sense. Indeed it’s the regular Zinsser (so waxed) and shop is unheated/metal shed so it’s getting very cold at night (below 60). I will try to heat it up a bit and see if it helps.

I assume you know that shellac is an alcohol based product and therefore it is flammable. As you “heat it up a bit” don’t get it near an open flame.

For your purpose, you may not care if the shellac contains wax. If you do, you can let the can sit motionless for a week or so. The wax will settle to the bottom and you can then decant the dewaxed shellac from the top being careful to not disturb the wax at the bottom. The cold temp may actually help with this process.

yes I was aware but never hurt to give the reminder… I planned on simmer the can in some hot water, don’t think the can needs to get super hot.
