When it comes to paint, there are no dumb questions...I hope. I have been priming till the cup runneth out. Waiting a day before sanding. Now I'm doing a few small areas and wondering if any remaining catalysed primer will last until I can sand and then reprime? If so, take it out of the gun and clean while waiting? I would read the can if there wasn't paint all over the directions..
Pretty much every product will have a TDS online somewhere that will give you the pot life. It won't be long enough to paint, let it dry, sand and repaint. Sent from my SM-G950W using The H.A.M.B. mobile app
Guessing every catalyzed primer has a little different dry time, but none of them will get you the kind of time you are asking about or you likely wouldn't be able to do the sanding you mention.
i usually mix half of what I think I’m gonna need. After I shoot that I kind of see if I was close on my guess and then readjust the second half up or down to finish. With the Catalyzed stuff once you mix it you got to shoot it or throw it out
Ha, yeah I went back out to spray the rest, already getting thick in the gun. Was a small load, maybe 1/4 cup to start with.
You can slow it down by putting it in the fridge. It might give you an hour or two. A paint rep taught me that trick.
And I'm told that $9.95 Harbor Freight guns are no good. Clean the gun first, mix paint, squirt it and through it away. Experts will argue that the finish won't be good, but you sand all the primer anyway. So I have 4 in the cabinet and nothing to paint yet. RB
" I would read the can if there wasn't paint all over the directions"" I can relate to that! I'd bet that I pour from the directions side of the can at least 90% of the time. Got no clue what makes me do that. I read the directions before I open the can but don't remember for vary long.
I prepared myself to have issues, used gun three times over 6 month period and never had issue, two part primer or finish Acrylic Enamel. Never had to throw away, so I got 5 or 6.
Well I finally, finally after 40 years of doing this off and on, got a couple of those rubbery bibs that hook on the lip of the can. Unfortunately I didn't get them until I bought the gallon of color, long after the primer. They work great. Nice little loader btw. If my wife ever baked a lasagna I'd paint the whole friggin' kitchen.
It wouldn't probably work at the paint is going through a chemical reaction but I wonder if you shot some mig gas into the pot if it would slow down the processs...
epoxy does not cure when less than 50 degrees. i never throw away that last little bit in the gun, it goes in the fridge for little touch up stuff. and, even a 1/2 a gun's worth will last in the fridge for two weeks, maybe longer, i havnt tried it. it looks normal after stirring, never know it was 2 weeks old. i like to add some new mix to it if i have enough parts to spray, but not necessary.

I always cut the label off the can before I open it and put it away. Then mark the can so I know which label goes with which paint. I mark it on the side and on the bottom.
i just shot some SPI 2 part primer today . tech sheet says have all of it done in 30 minutes. it does set up pretty quick , i've never tried the fridge method.
I dont think drinking that much beer to make room before painting would result in a good paint job. Good thing you sand most of it off.
