How long is unopened paint good for.

caminncMarch 18, 2012

I have a can of SW "Superpaint" Interior latex in the garage for about four years now an have never opened it. Is it still good? Thanks.

It's probably fine if the lid is on tight and it hasn't frozen. Paint sitting in the can for a year or more though usually needs to be strained. You can pour the paint through a paint strainer or some old nylons to get the little chunks out.

Yep...if it ever froze, it's GONE.

Stir with a paint-stick, scraping it across the bottom & sides firmly. Then use "rising" stir motions.
Have a paint-shop shake it if doesn't smell bad.
If test-brushes out smooth, and there's no "cottage-cheesiness" to it, you're golden! PG said...strain it.

Thank you both. I am not 100% sure it's never frozen but I wouldn't think so. The can is not rusted and looks new. The paint is very smooth with no lumps or cottage-cheese. There is no strong or bad smell either. It was stored on an interior side wall. I will stir well and strain just because you said to. Is there any way to tell if it has ever frozen?
