Ah, gouache! That magical, opaque paint that makes colors pop and brings your artistic visions to life. But, like any good thing, gouache needs a bit of TLC to stay in tip-top shape. Here’s how to keep your gouache paint from turning into a moldy mess or cracking like old concrete.

Why Does Gouache Get Mold?

Mold loves moisture, and guess what? Gouache is a water-based paint, which makes it a prime target for those pesky mold spores. If your gouache is lounging around in a damp, humid environment or if the lid is left open, it's basically inviting mold to the party. The organic stuff in gouache—binders and pigments—provides a moldy buffet.

How to Prevent Gouache from Cracking

Cracking paint isn’t just an old-school rock band; it’s a real problem. Here’s how to avoid it:

  1. Layer It Lightly: Thin layers of paint are like a good diet—moderation is key. Thick layers are like cake without frosting: dry and prone to cracking.
  2. Give It Time: Let each layer dry fully before piling on the next. Think of it as giving your paint a nap between sessions.
  3. Control the Climate: Keep your studio’s humidity at a Goldilocks level—not too dry, not too wet. Your gouache doesn’t want to feel like it's in a desert or a swamp.
  4. Mix Wisely: Don't over-dilute your gouache. It’s not a science experiment, just a good, balanced mix will do.

How to Keep Gouache Paint Fresh

Nobody likes crusty paint. Here’s how to keep your gouache as fresh as morning dew:

  1. Seal the Deal: Tighten those lids like you’re closing a treasure chest. No air means no drying out.
  2. Cover Up: When using a palette, slap some plastic wrap over it like a cozy blanket when you’re done.
  3. Rehydrate with Care: If your gouache gets a bit dry, add a smidge of water. Just don’t turn it into soup.

Should You Seal Gouache?

Sealing gouache isn't usually necessary unless you’re going for extra protection. If you must seal it, use a fixative or varnish made for water-based paints. Always test it first—nobody wants a surprise makeover.

How Do You Protect Gouache?

Treat your gouache like royalty:

  1. Store Like a Pro: Keep it cool and dry, away from the harsh glare of sunlight and extreme temperatures.
  2. Stay Clean: Use clean tools and palettes. You wouldn’t want old paint partying with your fresh gouache.
  3. Check Regularly: Give your supplies a little inspection from time to time. Catching problems early is key.
  4. Clean Up: After painting, scrub those brushes and palettes to avoid mixing old and new paint.
  5. **Use Anti-Fungal Mildew Spray: To prevent mold growth, consider using a specialized product like Anti-Fungal Mildew - Gouache Spray - 200ml.
