Can You Reconstitute Gouache?
Rick asked me: "Can [gouache] paint which has completely dried and hardened in its tube be rescued and reconstituted to an original consistency, after it has been stored too long?" I didn't feel sure of the answer, so I posed it to the Group Mind on Facebook:
Theresa M Quirk No. I think it goes in the garbage
Паулина Зетина Mine are very hard and I think to cut the tube because it's hard to paint without it but mine were hard after 5 years I say that to me if it works
Robert Tunstall it can't be brought back to its former glory. It does have limited use as a watercolour substitute though. As for tips, I store the tubes cap down on a wall rack I made. I drilled holes in a strip of wood.
Brad Fuller Nope, but it can be used as an indicator you aren’t painting enough.😀
Randy C. Spear Yeah Rick...how long has it been ? Over 30 yrs? LOL!!!
Dirk Shearer Amateur experience: I once poured gouache into little film containers for some reason. Over the years they dried up, and I was able to reconstitute it slowly back to a paste constituency. I’m not a gouache expert, and the gouache I used was not high quality, so I can’t speak to the quality before and after, but I was able to paint with the gouache again to a degree.
Robert Tunstall if they dry out, check they still adhere to paper when applied thick. if not, a touch of gum arabic will help with adhesion.
Cathy Johnson I squeeze mine into a travel palette and allow it to dry. Before painting, maybe 5 minutes before, I rewet and allow to sit. Not the SAME as fresh, but fine for working in the field in my journal. (Some brands rewet better than others...I have the best luck with M. Graham and Schmincke...)
Robert Tunstall schmincke has a finer grind of pigments than WN. It always causes me trouble when using the two brands as they need different amounts of water to achieve the thickness of cream.
Marcus M Mashburn Just stayed up all night doing 6 gouache illustrations. You sure can reuse them. I cut the tube open and grinde them with a mortar, pestle and water. If I'm out a color, I look in the dry tube box. Works great at 2 AM.
Lucille Halfon Dan Yes, absolutely. Except for the earth colors, which usually don't soften well. Remove the dead gouache tube, let pigment soak in water for a while. Then, 'grind' the color with a firm bristol brush. You may, or not, add a bit of glycerin for added gloss.
carlydraws I had some success crushing up the dried paint in a pestle and mortar and then soaking it in water and remixing. It was not quite the same as before but was usable!

Take the top off and soak in water for several days. Repeat as it only softens near the top. You might also squish it a few times to help the process of absorbing water back into paint. I've also thought of using a syringe with very thin needle to squirt water into paint tube.

The most I've been able to do is cut open the tube and have the chunks go into a dedicated pallete well and alternate between wetting it and mushing it in so it fuses. But then it's basically a watercolor cake, it doesnt have that acrylic vibe anymore.

If all you want is portable, opaque paint, then I do suggest using small containers of poster paint instead since they keep their fresh consistency & rewet better when dried Eh, definitely less painterly than gouache, but it gets things done
