Saving paint is a small action that can make a big difference—especially if you paint often, work with expensive colors, or care about the environment. Many artists and DIYers face the same frustration: mixing a perfect color on their palette, only to find it dried up and useless the next day. The good news is, with the right techniques and materials, you can keep your paint fresh and avoid unnecessary waste. Whether you use acrylics, oils, or watercolors, there are practical steps you can take to cover your palette and save paint for your next creative session.
This article guides you through the best ways to cover a palette, why it matters, and how small changes in your routine can stretch your supplies further. You’ll discover real-world advice, simple science, and a few creative tricks that even experienced painters sometimes overlook.
Why Saving Paint Matters
When you cover your palette, you do more than just save money. You also:
- Preserve color mixes: Getting an exact shade again can be difficult. Saving your mixes saves time and frustration.
- Reduce waste: Less dried paint means less thrown away, which is better for the environment.
- Stay organized: Keeping your palette clean and your paint usable helps you work faster and more efficiently.
According to a 2022 survey by the American Art Materials Association, nearly 60% of painters admitted to wasting at least one-third of their mixed paint each session. Over a year, that adds up to hundreds of dollars and many wasted hours.
Understanding Different Paint Types
Not all paints behave the same way. The best method to cover your palette and save paint depends on what you use.
| Paint Type | Drying Time (Open Air) | Best Covering Method |
|---|---|---|
| Acrylic | 10-30 minutes | Airtight cover, moisture retention |
| Oil | 8-24 hours | Loose cover, cool storage |
| Watercolor | 5-15 minutes | Seal or rewet before use |
Acrylic paints dry quickly and need moisture to stay usable. Oil paints dry slowly, so they are easier to preserve, but still need protection from dust and air. Watercolors can be reactivated with water, but it’s best to keep them covered to avoid contamination.
The Main Ways To Cover Your Palette
How you cover your palette depends on your needs, tools, and paint type. Here are the most effective methods:
1. Plastic Wrap
Plastic wrap is a cheap, simple way to cover your palette, especially for acrylics.
- How to use: Lay a sheet of plastic wrap tightly over your palette, making sure it touches the paint. Seal the edges as best as possible.
- Benefits: It creates a barrier to air, slowing drying time.
- Tips: For extra protection, mist your paint with water before covering. This works well for acrylics, but not oil paints.
2. Airtight Palette Boxes
Specially designed airtight boxes are available for most paint types.
- How they work: These boxes have a rubber seal that locks in moisture and keeps air out.
- Best for: Acrylics and water-based paints.
- Extra tip: Some boxes have built-in sponges to keep the air inside humid, giving you even more time before the paint dries out.
3. Damp Paper Towels
For acrylics, placing a wet paper towel over your paint before covering can make a big difference.
- Why it works: The towel adds moisture and slows evaporation.
- How to do it: Dampen (not soak) a clean paper towel, lay it gently over the paint, and cover with plastic wrap or a lid.
4. Aluminum Foil
Aluminum foil is another quick option for oil and acrylic paints.
- How to use: Press the foil gently over your palette, forming it to the paint blobs and surface.
- Pros: It blocks light and air, and is easy to shape.
- Cons: Not as airtight as plastic wrap, but great for short-term storage.
5. Palette Lids
Some palettes come with matching lids. If yours does, use it!
- Advantage: Quick, reusable, and often fits perfectly.
- Extra tip: Wrap the palette in a plastic bag before putting on the lid for extra protection.
6. Resealable Plastic Bags
For smaller palettes or paint mixing trays, a large resealable bag (like a Ziploc) can work well.
- How to use: Slide the palette inside, press out as much air as possible, and seal tightly.
- Good for: Acrylics, watercolors, and even small oil palettes.
7. Wax Paper
Wax paper is a gentle option, especially for watercolors or when you want to avoid static.
- How to use: Lay wax paper over the paint and press lightly to seal.
- Note: Wax paper is not airtight, but it helps prevent dust and slows drying for a few hours.
8. Cling Film With Moisture Reservoir
Some artists use cling film stretched over a palette with a damp sponge or paper towel underneath.
- Why: The moisture source keeps the air humid, greatly extending paint life.
- How: Place a damp (not wet) sponge in the corner of the palette, then cover with cling film and seal.
9. Silicone Palette Covers
Silicone lids or sheets offer a reusable, flexible solution.
- Best for: Odd-shaped palettes or frequent painters who want to avoid single-use plastics.
- How to use: Stretch the silicone over the palette for a tight seal.
10. Diy Wet Palettes
Wet palettes are a favorite among acrylic painters.
- How to make one: Use a shallow, airtight container. Place a sponge or several layers of wet paper towel on the bottom, and a piece of parchment paper on top to hold the paint.
- Result: Paint stays moist for days—even weeks.
- Tip: Change the water every few days to prevent mold.
11. Refrigeration
Chilling your covered palette can double or triple paint life—especially for oil and acrylic paints.
- How to do it: Cover your palette with any airtight method (plastic wrap, lid, bag) and place it in the fridge.
- Warning: Clearly mark the container as “art supplies” to avoid confusion with food.
12. Freezing
For even longer storage, freeze your covered palette.
- How: Use an airtight container or heavy-duty bag. Place the sealed palette in the freezer.
- When to use: For oil paints or large mixes you want to keep for weeks.
- Note: Let the palette reach room temperature before using again.
13. Glass Palettes With Covers
Glass palettes are easy to clean and can be covered with another piece of glass, acrylic, or a tight-fitting lid.
- Why use glass: Smooth, non-porous, and paint peels off easily.
- Tip: For a better seal, add a thin bead of petroleum jelly around the edge.
14. Custom Diy Palette Covers
If you have a unique palette shape, make your own cover from cardboard, plastic, or even old food containers.
- How: Cut the material to size, and use rubber bands or clips to hold it on.
- Pro tip: Add a strip of foam or felt around the edge for a tighter seal.

Mistakes To Avoid
Even experienced artists sometimes make simple mistakes that lead to wasted paint. Here are a few to watch out for:
- Not sealing edges: Air sneaks in through gaps, drying paint quickly.
- Using dry paper towels: Dry towels pull moisture from acrylics—always use damp towels.
- Leaving palettes in hot rooms: Heat speeds up drying. Store palettes in a cool place.
- Forgetting to label: If you freeze or refrigerate palettes, label them clearly so nobody mistakes them for food.
- Overloading the palette: Mix only what you need; large piles are harder to cover and keep fresh.
Non-obvious Insights For Beginners
Many beginners miss these two key points:
- Humidity matters: The drier your room, the faster paint dries—even under covers. In dry climates, a wet palette or a moisture source is almost essential for acrylics.
- Paint thickness: Thicker piles of paint dry more slowly than thin ones. If you know you’ll need a mix again, keep it in a small mound rather than spreading it out.

Cleaning And Reusing Covered Palettes
Don’t forget to clean your palette regularly, even if you cover it well. Residue can affect new mixes, and mold can develop if you use damp methods for long periods.
- Acrylics: Peel dried paint off plastic or glass palettes.
- Oils: Wipe excess off with a rag and a bit of solvent.
- Watercolors: Rinse with water; leftover paint can be reused.
Reusable covers (like silicone lids or airtight boxes) should be washed after each use to prevent unwanted color mixing.
Saving Paint Beyond Covering
While covering your palette is the easiest way to save paint, these extra habits will help you waste less:
- Use a stay-wet palette for acrylics: These keep paint moist and usable for days.
- Mix small amounts: Start with less—add more only if needed.
- Scrape and store: Leftover paint can be scraped into airtight containers for future use.
- Rehydrate dried paint: Some acrylics and watercolors can be brought back to life with a spritz of water.

Frequently Asked Questions
How Long Will Covered Paint Last On A Palette?
It depends on the paint type and covering method. Acrylics can last 1–7 days if well covered and refrigerated. Oils may stay usable for up to a week, especially if chilled. Watercolors can be reactivated even after drying, but will stay cleaner if covered.
Can I Use Leftover Paint Again?
Yes, as long as the paint has not fully dried out or become contaminated. For acrylics and oils, check for a skin on top—if it’s still soft underneath, you can use it.
What Is A Wet Palette, And Do I Need One?
A wet palette is a special palette with a moisture source underneath the paint. It’s especially useful for acrylic painters, as it keeps paint workable for much longer. You can buy one or make it yourself at home.
Is It Safe To Put Palettes In The Fridge Or Freezer?
Yes, as long as you clearly label them and keep them away from food. Use an airtight container to prevent odors or contamination.
What Is The Best Cover For Oil Paints?
For oils, a loose-fitting lid or plastic wrap is usually enough. For longer storage, refrigerate or freeze the covered palette. Avoid wet paper towels (which can add water to oils).
Covering your palette is a simple habit that saves paint, money, and time. With a little preparation and the right method for your paint type, you’ll spend less time mixing and more time creating. Try a few of these methods and see which works best for your style and studio.
