Is it safe to use opened and unopened interior paints that have been stored outside in extream heat and cold?

Question

and did you have to use primer hoping to paint over old paint

Answer 1

If there is enough in the cans, some stores will re-agitate them for you. You could buy a mixing attachment for your drill and remix them yourself. Or just stir with one of those mixing paddles. They are probably still good if they were well sealed and rust has not started to eat through the tin. Start buying paint in plastic containers. They seal better and are easier to mix in.
If your existing paint is older than three years or is trim paint that has dirt on it you will get better results if you use primer first.
If you want to dispose of your paint, you should open it to the air and let it dry in the container before putting it into the landfill.

Answer 2

If its been allowed to freeze then i would say its no good ,even if its paintable you wont nesicarly get the true color it once was and after awhile it will start getting clumbs i would just get another can , with primer, reasons to prime 1 old paint is dirty and you cannot clean 2 if you are completly changing the color drastically ie was white now painting dark red 3 the old paint is oil and the new is latex, 4 if its a glossy surface other than that if its a light color going over a light color then you should beable to top coat it fine.

Answer 3

if it is latex paint you can't use it no longer good after freezing If the pain is oil based it should be ok

Freezing does ruin latex paint, but it can survive a few freeze/thaw cycles. Allow the paint to slowly warm up to room temperature, then stir it well. If the paint color and consistency appear normal, then it should be all right to use. If it looks like cottage cheese, it was frozen too long and you should let it dry on newspaper in a safe place, then put it in the trash.

Answer 4

If you are painting over old paint just lightly sand it to key the surface. Give your paints a stir, and if they don't separate and look odd they're probably fine. Handy tip: Store opened paint tins upside down, so the congealed hardened layer is at the bottom and reseals the paint. Just be careful when re-opening them as they are now full to the brim and top-heavy. Good luck

Answer 5

Extreme temps will render the paint ruined, so try to find a way to dispose of it. Most Sanitation Companies, won't haul away paint cans.

Answer 6

i would not use the paint it is long gone say goodbey and trash them and you do have to prime before you paint.so the paint will stick to the primer if you do not prime the paint is just going to peel right off.so go to the paint store pick out a cheap primer and a nice paint color and go for it have yourself a bueatyful room.

Answer 7

coldl will ruin the paint. Under 100 degrees heat, just stir it and test somewhere. may still be good

Answer 8

Usually the pigments have congealed, as a hard coating on top of the contents, and the color is not true any longer.

Answer 9

No. They are probably ruined.
