OOPS! 20 cans of spray paint won't spray; what can I do???

Question

They were in a box that got put in our outdoor storage shed by mistake. Now they have little lumps, and no matter how much I shake (stir) them, the nozzle keeps clogging. Is there ANYthing I can do to make the paint ok again? They are Krylon Satin Touch Designer Finish or Krylon Home Decor Latex; 12 oz (dries in 12 minutes or less) for inside and out, for use on wood, metal, plastic, wicker, etc. in 4 or 5 different colors) and I think the Arizona heat has ruined them! I really don't want to have to pitch them. What can I do? Pleeeeese help.

Answer 1

Lots of shaking little mamma. Hoo ho lot of shakin' going on. Thank You, thank you very much. Seriously, if you shake the devil out of the can and keep shaking them while you are using them they will work better. I would find some extre nozzles from other cans that work so you could switch them when they get clogged. Soak the clogged ones in a small jar of paint thinner for a while and they will work again.

Answer 2

You can, but it must be completely smooth with no lumps or areas where the wallpaper is coming loose from the wall. Start with a high adhesive primer after you have thoroughly washed and dried the wallpaper (it must be immaculately clean or you'll regret it later). After your primer has dried, paint one or two coats of color and it should look like the paper was never even there. Although, this is the easy way out - it's always better in the long run to go ahead and remove the wallpaper.

Take the cans that are labeled latex and uncover them. Put them in a tub of water to soak a couple of days. Pull them out and shake them a few times over those couple of days.
The ones that say enamel, if you can't get them to work like Robert C suggested doing, pitch them.
Do not soak them in thinner it is very dangerous. Fire hazard and the thinner fumes.
Good Luck. If it was me I would just dispose of them safely and buy new.
