I have several buckets of four-year old latex paint leftover from finishing our basement. Many are still in unopened original containers, in particular, our primary wall paint.
I opened one to use for wall patching and found it to be completely separated. This bucket was also in the garage and was subjected to freezing temperatures.
With just a little bit of stirring it seems to be back to life, but I just want to be sure that I won't have any adverse affects using it to patch several chips and scuffs around the house.
How long is the shelf life for latex paint?
