Latex Paint Question
Posted on 5/26/24 at 5:03 pm

I have a gallon of white exterior paint that has never been opened. If I shake the can thoroughly, can I still use it, or should I buy a “fresh” gallon?

I've used old latex before and have had mixed experiences. Sometimes it is fine, I'd say most of the time. A couple times when I've used it the paint seems to never "cure" and stayed sticky/tacky pretty much forever. Maybe it has to do with how it was stored or the quality of the paint to begin with.
You could always shake it and paint something to test it and see how it works.

Bring it to store and get them to shake it in their paint shaker.

Ive used latex as much as 10 years old and its seemed fine. I knew for a fact that it had never been frozen though.

Open it, check to see if the top layer is still liquid or if it has solidified a bit.
If it has solidified, it will still be very flexible so you can take a very sharp knife and cut it loose from the can and then remove it as carefully as you can so it doesn't break up into the remainder of the paint.
Then put the lid back on and shake it or use one of those paint stirring paddles in a drill to thoroughly mix it and it should be good to go.
If any of the paint looks like it has crap in it, then get some paint strainers and pour the paint through it to get any debris out.
I miss the old days when women wore pantyhose. Those things made good paint strainers.

Better open it and check it first to make sure the surface hasn't got that dried cap on it or you'll have trash in the entire gallon to deal with.

It does have a shelf life. But bigger problem would be if it had froze in the past. If it hasn’t been through a freeze/thaw cycle a time or 2, just stir until all the solids are mixed back in. Scrape bottom with stir sticks and get everything off bottom. After that a good shake or mix with drill and paddle attachment will work

Depending on what you are using it on, consider the hassle of potential problems vs the cost of a new can of paint. A year or two, never frozen, probably good. Consider the risk.
