shelf life of paint


Getting ready to paint, but it may be a week or so. Plan to use S-W Superpaint, and I see that S-W has a 25% off sale this week, and I'd like to take advantage of it. Any problem with storing the paint for a week or two in the garage? I know they store paint, but don't know if it's different after it's tinted. Do they sell it in 5 gal cans or all 1 gal. How often do they run these sales? They had a 40% off for 1 day a couple weeks ago, but the wife couldn't decide on a color that fast.

The paint will easily be fine for a week. Just shake um real good before you open it. That's kinda hard to do with a 5 so you can just stirr it. Most paints will come in 5's but it depends on the sheen, base, and availibilty at the time.

FYI...you could have bought all the paint you needed during the 40% off sale then had it tinted to the color you wanted at any point for free from SW.

i just touched up a ceiling the other day with some snow white from 2004. actually painted just fine, i did however have to stir the holy hell out of it before and strain. very very little break down was present. that's probably the upper limit of what i would ever try though. normally when latex goes bad it gets clumpy , dries out or does not apply well when you go to brush it on.

Thanks Racebum. I read once that it's best to store opened paint upside down, so air cannot enter the can. Works good,...as long as the top is on tight.

If the top IS TIGHT, it makes absolutely no difference, think about it, the air is still in there upside down or not.

I agree. People telling you to store paint upside-down is just making stuff up as they go along.

And it only takes one top leaking or rusting out to decide that is a bad practice

It has been my experience that mixed paint will last for years. However it will need stirred real well. The best way to do this in a 5 gal pail is to get one of these stirrers that go into your electic drill and stir it and stir it and.....stir it. The advantage of storing paint upide down is that the solids will be on the top and makes it easier to stir.

That is the way to mix it and that is also why people store paint upside down, paint does have a shelf life, it various and is different for water and oil base, but will usually last a few years, especially unopened.

Would not the solids just gravitate down to the lid?

Upside down or right side up the solids will always move to the bottom,I see NO advantage to storing them upside down.
