Why cover unused gouache paint
Gouache paint is a popular medium among artists due to its vibrant colors and versatility. However, it is common for artists to have leftover or unused gouache paint after completing a project. In order to prolong the lifespan of your gouache paint and maintain its quality, it is important to cover and store it properly.
Prevents drying out
One of the main reasons why you should cover unused gouache paint is to prevent it from drying out. Gouache paint is water-soluble, which means it can easily evaporate when exposed to air. By covering the paint, you create a barrier that slows down the evaporation process, keeping the paint moist and usable for a longer period of time.
Preserves paint quality
Covering unused gouache paint also helps to preserve its quality. When gouache paint is left uncovered, it is exposed to dust, dirt, and other contaminants that can affect the quality of the paint. The pigments may become less vibrant, and the consistency of the paint may change. By covering the paint, you protect it from external elements, ensuring that it remains in optimal condition for future use.
Another benefit of covering unused gouache paint is that it can help you save money. Gouache paint can be expensive, and allowing it to dry out or become contaminated can result in wasted paint and wasted money. By properly covering and storing your gouache paint, you can prolong its lifespan and avoid unnecessary waste, ultimately saving you money in the long run.
Covering unused gouache paint is also an environmentally conscious choice. By preventing the paint from drying out or becoming contaminated, you reduce the amount of paint that needs to be thrown away. This helps to minimize waste and contribute to a more sustainable art practice.
Options for covering unused gouache paint
Now that you understand the importance of covering unused gouache paint, let’s explore some options for effectively protecting your paint.
Using plastic wrap
Plastic wrap is a simple and readily available option for covering your gouache paint. Here’s how you can use it:
Wrap tightly around paint palette: Start by wrapping the plastic wrap tightly around your gouache paint palette. This will create an airtight seal, preventing air from reaching the paint.
Secure edges with tape: To ensure that the plastic wrap stays in place, secure the edges with tape. This will help to maintain the integrity of the seal and prevent any air leakage.
Press out air bubbles: As you wrap the plastic wrap around the palette, be sure to press out any air bubbles. Air bubbles can create pockets of stagnant air, which may lead to the paint drying out faster. By eliminating these air bubbles, you create a tighter seal and provide better protection for your paint.
Using an airtight container
Using an airtight container is another effective method for covering your unused gouache paint. Follow these steps to properly store your paint in a container:
Choose a clean and sealable container: Select a container that is clean, dry, and has a secure lid. Glass or plastic containers with airtight seals are ideal for preserving the freshness of the paint.
Transfer the paint into the container: Carefully transfer the unused gouache paint from your palette into the chosen container. Be sure to scrape off any excess paint from your palette to minimize waste.
Seal tightly to prevent air exposure: Once the paint is in the container, seal it tightly to prevent any air exposure. Make sure the lid is securely fastened to create an airtight environment for the paint.
Using a palette with a lid
Investing in a palette with a lid is a convenient option for covering and storing your unused gouache paint. Follow these steps to effectively use a palette with a lid:
Invest in a palette with a lid: Look for a palette specifically designed for gouache paint that comes with a lid. These palettes are typically made of plastic or porcelain and have individual wells for each color, making it easy to keep your paint organized.
Place the unused gouache paint on the palette: Squeeze out the desired amount of paint onto the wells of the palette. Make sure to only dispense the amount of paint that you will be using, as excess paint can be difficult to store and may go to waste.
Close the lid tightly to keep the paint moist: Once you have placed the paint on the palette, close the lid tightly. This will create a sealed environment within the palette, preventing the paint from drying out and maintaining its moisture.
Using a wet palette
A wet palette is a great option for artists who prefer to work with gouache paint in a more fluid and easily blendable state. Here’s how you can use a wet palette to cover and store your unused gouache paint:
Prepare a wet palette with a sponge and palette paper: Start by soaking a sponge in water and placing it on a palette tray or container. Next, lay a piece of palette paper on top of the sponge. The sponge will provide moisture to the paint, while the palette paper acts as a surface for mixing and storing the paint.
Dampen the sponge and place it on the palette: Wet the sponge by adding water to it. The sponge should be damp, not dripping wet. Place the damp sponge on the palette tray or container, ensuring that it covers the entire surface area of the palette paper.
Disperse the paint on the palette paper: Squeeze out the desired gouache paint colors onto the palette paper. The dampness of the sponge will keep the paint moist and workable for an extended period of time.
Cover the wet palette with a lid or plastic wrap: To maintain the moisture in the paint, cover the wet palette with a lid or plastic wrap. This will create a humid environment that prevents the paint from drying out and allows for easy rehydration when you are ready to use it again.

Potential issues with covering unused gouache paint
While covering and storing your unused gouache paint is crucial for its longevity and quality, there are potential issues that you may encounter. Understanding these issues will help you take the necessary precautions to avoid them.
Mold or bacterial growth
One of the main concerns when covering gouache paint is the potential for mold or bacterial growth. Here are some tips to prevent this issue:
Use clean brushes and water: Prior to mixing or using your gouache paint, ensure that your brushes and water are clean. Use fresh water for each painting session to prevent the introduction of any contaminants.
Avoid introducing foreign substances: Be cautious when adding additional mediums or additives to your gouache paint. Verify that they are compatible with gouache and won’t introduce any foreign substances that may contribute to mold or bacterial growth.
Store in a cool, dry place: It is important to store your covered gouache paint in a cool, dry place. Avoid storing it in areas that are prone to high humidity or excessive moisture, as this can create an environment conducive to mold or bacterial growth.
Regularly check the paint for signs of growth: Inspect your covered gouache paint regularly for any signs of mold or bacterial growth. If you notice any discoloration, strange odors, or changes in texture, discard the paint immediately to prevent contamination.
Another issue that can arise when covering gouache paint is color separation. Here’s how you can avoid this problem:
Mix the paint thoroughly before covering: Before covering your gouache paint, make sure to thoroughly mix the paint using a palette knife or a clean brush. This will help to ensure that the pigments are evenly distributed and reduce the likelihood of color separation.
Use airtight containers or palettes: Opt for airtight containers or palettes when covering your paint. These containers provide a better seal, preventing air from reaching the paint and reducing the chances of color separation.
Avoid prolonged exposure to air: When working with gouache paint, avoid leaving it exposed to air for extended periods of time. The longer the paint is exposed to air, the higher the risk of color separation. Cover the paint as soon as you finish working with it to minimize this risk.
