POR-15 storage without drying?
 

Has anyone figured out how to do this? The stuff is expensive, and I seem to only need it a dab or two at a time. But when I open up a quart, and try to reseal it, it dries to as hard as a rock. I even tried pouring it into little paint jars but sure enough it all dried up. Anyone else having this problem?

is it only drying out on top? If so, try storing it upside down and it will remain usable from the open end.

OMG - I feel you pain.

Bought my first quart last year.

Used some and had residue on the lip of the quart paint can.

That was trashed opening the can up next time.

Put it in a big plastic medicine bottle. Have not tried to open it since.

Fully subscribed.

I was able to reuse a quart several times over a pretty long period by putting a piece of saran wrap in between the lid and can each time. Not my idea, the guy i bought it from recommended it.

It goes a long way. Even if I need lots I only buy the smallest little cans.

I turn it upside down and use a self tapping screw to drill a hole in the can to let it drip out (or dab my brush in it). Then I seal it up again by screwing in the screw. The dried paint seals the screw so no more air will get in.

I can easily remove a screw, but I can never remove a dried on top.

Great minds think alike, LOL. I got a quart about three years ago, did your self tapping screw
trick (actually 2 screws to make pouring easier with an air bleed), but in the top lid, not bottom. Haven't used it in a couple of years, and just checked last week, it's in great shape, just like new!
What ever you do, NEVER pry off the top!! POR15 contains isocyanates and is cured by moisture.The moisture that gets in when you open the can is what cures and hardens the paint!

OK I like the screw idea - do you screw in the screw through the original top? Does it excessively leak out when you turn it upside down?

Like the Saran Wrap idea too ... Keep me coming.

I just buy a 6 pack of the 4oz cans, and use plastic between the lid and can.

I put my extra POR15 in a plastic container with a snap on lid, like Tupperware. Then stored it in my garage, aka beer refrigerator. That stuff lasted a couple of years stored that way.

Didn't open the can until I had a bunch of baby food jars ready. I filled each one, saran wrap. then shut it. Put them all into the refrigerator. Used up one jar at a time. Each jar allows a few opening and closings before either ran out or it hardened. Just bought another can... but I like the screw idea... maybe one on top and one one lower side so you can just let it pour out as much as you need.

Mine is in my fridge.

You might also try spraying argon gas in the container before sealing it up again. Argon is inert and displaces air. You may find it in a wine/spirits shop.

Just put self tapping screws in the top lid on opposite sides. It won't leak, because you screw the screws down till the head contacts the top and the paint inside seals it.
To use, remove both screws (so you have an air bleed) and pour out what you need. Easy peasy!

I don't mean to be a dream smasher... but you know POR-15 is just Wurth paint. Don't believe me? Check under your labels (especially on older cans). Literally just re-labeled over the old.

Here's my very old can of POR15. Got it unopened from another Pelican on the for sale
forum. He said he'd had it on the shelf for many years. By the looks of the can, must have be many, many years. Anyway, this is the can I did the screw trick to three years ago, I used about a quarter of it and the contents are still as liquid as water!

Yea right! How do you check under a painted on label! By the way, this IS a very old can!
Wurth does sell a similar product (probably identical formula) just a lot more expensive. 160z POR $31.00 vs 16oz Wurth $48.00
Guess the German name costs more!

Enjoy!

Or maybe the Wurth paint is just relabeled POR15?

The Wurth label isn't removable and is on bottom. Same product just different art work on the can here ... others can peel their labels to check as well.

Check Google search results on this question. It's only news here but known for a long time by the rest of the world. Doesn't detract from the effectiveness of the product but maybe some the mystique.
