Q. I started a project a month ago to paint some interior walls but I got too busy to finish, can I continue with interior paint that has been sitting in our garage in below freezing temperatures to work again? I was wondering if I need to go buy another can of the same paint instead of messing up and taking a risk of using what I have already started to uset. Can anyone help me before I begin the project again. HELP!
Just FYI...the paint is water based. Hope that helps when answering the question. Thanks! :)

A. There is no "set" answer to this, as paint comes in a vast number of chemical combinations, and it depends on the paint you have.
A very broad answer is that some water-based paints will not survive. Others will survive, but may dry with a flaky or loose finish when applied. Some will work nearly, or fully, as well as before.
Oil-based paints are harder to predict. The solvents will be undamaged, but the solids may congeal and become useless.
All you can do is to slowly thaw your paint indoors, (do NOT apply any heat to speed it up,) then try to mix it. If it mixes well, try it on a spare piece of material and let it dry for a few days, then examine it and rub it with a coarse cloth to test its staying ability.
Note
Once it is fully dry, compare the newly-painted piece with whatever you painted before, as the frozen paint may have acquired a colour shift.

Would painting over interior paint with exterior paint on an outside wall hold up in the elements?
Q. I was given the wrong paint while working on a project, and am now worried about the paint buckling because it is interior paint on an outside wall. Can I simply paint over it with exterior paint or would it still lead to buckling because of the binding in the interior paint?
A. Sorry to say but simply painting over the interior paint with an exterior paint will not work. The elements will break down the binding of the interior paint coating and start peeling or splitting both that coat and the exterior coat on top. How large was the area that you have to redo? The best thing is to remove the original layer of paint and re-paint. Unfortunately! You will be told that you can use other products or methods but none of them will work as well as stripping off that layer of interior paint.
Accidentally put interior paint on the exterior of my home?
Q. There was a mix up at the paint store I guess. There was existing exterior paint on the trim, I painted it today with interior paint - can I just put exterior paint over it or do I have to strip it off?
A. You should be ok, especially if the paint was oil/solvent based rather than water based. Whenever you choose to repaint there is no need to strip this off.
