A wet palette is a system that keeps your acrylic paints fresh and ready to use for hours, even days, using a container with a moist base and a semi-permeable membrane paper. If you paint miniatures, it's the ultimate solution to stop paint drying out on your palette, saving you time and frustration.
In my experience, it's one of those tools that completely changes the way you work. The mechanism is pure genius: a container, a layer of water-soaked absorbent material, and a sheet of special paper on top. Moisture slowly seeps through the paper and keeps the paint from drying out. Simple as that. ✌️

What exactly is a wet palette and why do I need one?
A wet palette is a sealed system that keeps acrylic paint at just the right moisture level, stopping that dreaded dry skin from forming and ruining your mixes. For me, it's an essential tool on my painting desk.
I can clearly remember the frustration of mixing a complex skin tone, nailing the exact shade, and having it dry out before I could finish the details. Not anymore! Since switching to a wet palette, my whole approach to painting has changed completely. It's a one-way trip, I promise you.
The benefits that will transform your painting desk
Once you start using one, the advantages speak for themselves. Here's why I can't live without it:
- Save paint (and money): No more throwing away dried-up blobs of paint. A single drop can last an entire session. Close it up properly and it'll stay workable for days.
- Mixes that last: Need a specific colour for a whole army? Mix it once and keep it usable for hours, maintaining perfect consistency across every model.
- Advanced techniques made easy: It makes wet blending and smooth gradients so much more achievable. You have far more time to work colour transitions without rushing.
- Stress-free painting: Being able to stop, make a cup of tea, and come back to your exact mix is priceless. No more racing against the clock before everything dries up.
And while there are some fantastic commercial options out there, I'm going to show you how to put together a homemade version that works brilliantly. If you catch the bug later on, you can always take a look at professional-grade wet palettes.
What materials do I need to make my own homemade wet palette?
Building your own wet palette is much easier (and cheaper) than it sounds, and chances are you've already got most of what you need at home. You don't need to spend a penny to start enjoying the benefits.
First, you'll need a shallow container with a lid. A simple plastic food storage container or even a clean takeaway tray will work perfectly. The lid is key — it's what stops the moisture from escaping.

Next comes the absorbent layer — the water reservoir. Keep it simple: 3 or 4 layers of kitchen roll are more than enough. Some painters prefer a thin cloth or a piece of sponge, both of which work just as well.
And last but not least, the key component of the whole setup: the palette paper. For a DIY version, baking paper or parchment paper is your best friend. Its magic lies in being semipermeable: it lets moisture pass through from below while preventing paint from seeping through and mixing with the water.
Wet Palette Materials Comparison
To give you a clear picture of your options, I've put together a table comparing DIY components with their professional alternatives. This way you can decide what works best for you.
| Component | DIY Option | Professional Option | Pros and Cons |
|---|---|---|---|
| Container | Plastic tupperware, repurposed container. | Low-profile airtight box. | Tupperware is free, but professional options are fully watertight. |
| Absorbent Layer | Paper towels, thin cloth. | Treated hydrophilic sponge. | Paper towels are cheap, but professional sponges are usually anti-mould. |
| Palette Paper | Baking paper or parchment paper. | Purpose-made hydrophilic paper. | Baking paper works well, but professional **replacement paper** delivers more consistent rehydration. |
From experience, I can tell you that not all brands of baking paper behave the same way — some are far too non-stick and impermeable. My advice: don't be afraid to experiment.
How Do I Build My Own DIY Wet Palette in 5 Minutes?
Setting up your own wet palette is ridiculously easy and cheap. Honestly, it'll take you longer to read this guide than to actually build one. All you need is a tupperware container, paper towels, and baking paper. Let's get started!
Take your tupperware and cover the entire bottom with 3 or 4 layers of paper towels. Ideally, the paper should cover the base and come up slightly along the sides. This will be your water reservoir.

Now, carefully pour in water until the paper is completely saturated. The sweet spot is fully soaked, but with no pooling. If you've added too much and see puddles forming, simply tilt the container and drain the excess.
The Trick to a Perfect Working Surface
Your base is now wet. Next comes the part that creates your actual working surface: the baking paper. Cut a sheet that fits snugly inside the tupperware, right on top of the wet paper towels.
Here's the crucial detail: it's essential that the baking paper lies completely flat and adheres to the wet base beneath. Use your fingers to smooth it from the centre outward, pushing out any air bubbles. Those bubbles are the enemy — they create dry spots where your paint will start to dry out prematurely.
And that's it! You've just built a tool that, I promise, will completely change the way you paint. All that's left is to put your acrylic paints on the paper and start enjoying the process.
Maintenance and upgrades for your DIY palette
Your homemade palette will serve you brilliantly, but it does need a little attention. The kitchen paper, being constantly damp, can eventually develop mold. The best approach is to replace it every few days and give the container a thorough wash.
If over time you find the setup isn't quite cutting it, or you simply want something more durable, professional replacement sponges are a fantastic upgrade. They're usually treated to prevent mold and hold water far more evenly.
How do I keep my wet palette free from mold and odors?
A wet palette is a miniature ecosystem, and like any ecosystem, it needs a little care to stop it turning into a breeding ground for mold and unpleasant smells. Trust me, there's nothing worse than opening your palette ready to paint and being greeted by a nasty surprise.
The key to avoiding this is simple: hygiene and temperature control. If you know you won't be painting for a couple of days, the golden rule is to pop the palette, sealed shut, in the fridge. The cold stops bacterial and fungal growth in its tracks.

My tips for keeping your palette clean and ready to use
I've heard all sorts of tricks, including dropping a copper coin in to prevent mold. Personally, I think nothing beats a solid cleaning routine. The most important thing is to replace both the absorbent layer and the palette paper regularly.
- How often should you change it? If you paint every day, I'd recommend refreshing everything at least once a week. If you notice the water going cloudy or starting to smell off, change it straight away!
- Water quality matters. Always use clean water. If you have distilled or demineralized water to hand, even better. Since it contains no minerals, it reduces the chances of anything starting to grow in there.
- Deep clean when all else fails. If mold still appears, it's time for a full disinfection. Throw away all the paper and the sponge, and wash the container thoroughly with soap and water. To finish, you can wipe it down with a little isopropyl alcohol.
If you go for a wet palette from a specialist brand, such as the Vallejo Pro Painter Wet Palette, maintenance becomes much simpler. They sell dedicated refills that come ready to use, including replacement paper and replacement sponges, which are typically treated to prevent issues from the start.
When is it worth buying a professional wet palette?
While the homemade version is a great way to get started, there comes a point where upgrading to a professional wet palette becomes one of the best decisions you can make. If you're serious about painting, it's an investment that more than pays for itself.
Models like the Vallejo Pro Painter Wet Palette are genuinely game-changing. Yes, there's an upfront cost, but in my experience it pays for itself almost immediately — in paint you stop wasting, time you save, and frustration you avoid.
The key advantages of a professional wet palette
Once you try a tool designed specifically for miniature painting, you understand why everyone raves about it. There's simply no comparison.
- A truly airtight seal. Professional wet palettes are far more airtight than any food container. That means consistent, long-lasting moisture — essential if you want that perfect mix to still be usable days later.
- Premium materials. The included sponge is treated to be anti-mould — the number one enemy of DIY palettes. The membrane paper has exactly the right porosity to keep paint hydrated without turning it watery.
- Convenience and durability. Everything — from the size to the ease of finding replacement inserts — is designed to make your life easier. These are robust tools built to handle daily hobby use.
Wet Palette FAQs
Like any new tool, the same questions tend to come up at the start. Here are the most common ones answered, so you can skip the rookie mistakes and get the most out of your palette from day one.
Why is my paint coming out too watery?
If your paints look like soup, you've got too much moisture. The most common cause is adding too much water to the base. Remember: the sponge should be saturated, but never flooded.
How often should I change the water and paper?
It depends on how often you paint. If you're painting most days, I'd recommend a full refresh once a week. If the water turns cloudy or starts to smell off, change it straight away to prevent mould.
Can I use any paper towel on the surface?
No — paper towel isn't suitable for the surface layer. You need a semi-permeable paper. Baking parchment (also called greaseproof paper) is the perfect DIY solution, as it allows moisture to pass through while stopping paint from soaking in.
How do I store the palette to keep my mixes fresh?
The key is an airtight seal. Make sure your lid fits snugly to prevent moisture from escaping. If you want to extend your paint mixes as long as possible, pop the palette in the fridge.
Final thoughts
By now, I think it's pretty clear — isn't it? A wet palette, whether you go DIY or invest in a professional one, is one of those tools that genuinely changes how you paint. No exaggeration — it's one of the best upgrades you can make to your hobby setup.
Trust me on this: no more throwing away paint because your carefully mixed colour dried up before you could finish. With a wet palette, your paints stay workable for hours, giving you the freedom to nail those blends without rushing.
My advice? Just try it. Start with the DIY version we covered. Grab a container, some paper towel, and a sheet of baking parchment. You'll be amazed at how well it works. And once you feel the difference, you might just find yourself ready to step up to a professional setup.
Either way, adding a wet palette to your painting station is, I promise you, one of the best decisions you'll make. Once you go wet palette, you'll never look back. Say goodbye to dried-out paint for good!
