Why Proper Storage Matters
Acrylic paints, while durable once dry, can be susceptible to damage if not stored correctly. Finished paintings require a safe haven from physical harm, temperature fluctuations, humidity, and light. Incorrect storage can lead to cracked paint, yellowing mediums, dust accumulation, and even permanent damage to the canvas. Investing time in proper art supplies storage and methods for your finished works is an investment in the longevity of your art.
Protecting Your Investment
Your acrylic paintings are more than just decoration; they are expressions of your creativity and potentially valuable assets. Proper storage safeguards this value. Ignoring best practices can lead to:
- Physical Damage: Scratches, dents, and punctures to the surface.
- Environmental Damage: Fading from light, mold growth from humidity, or cracking from extreme temperatures.
- Chemical Reactions: Degradation of paint binders or varnishes over time.
Long-Term Art Storage Considerations
When thinking about long term art storage, it’s important to anticipate how your paintings will be kept over decades. This involves creating an environment that minimizes any potential harm.
Preparing Your Acrylic Paintings for Storage
Before you even think about where to put your acrylic paintings, there are crucial preparation steps to take. These steps are vital for painting preservation and preventing future issues.
Ensuring Paintings Are Completely Dry
This might seem obvious, but it’s a critical step that’s often overlooked, especially for those just learning about drying acrylics. Acrylics dry to the touch relatively quickly, but they can take weeks, even months, to cure fully. Storing a painting that is not completely dry can lead to:
- Adhesion Problems: The paint film can stick to whatever it’s touching.
- Mold and Mildew: Trapped moisture within the paint layers can encourage growth.
- Smudging or Lifting: The paint can be easily damaged if it’s not fully hardened.
How to Tell if Your Acrylics Are Truly Dry:
- Touch Test: Gently touch a less conspicuous area. It should feel completely solid and not tacky at all.
- Cure Time: Consider the thickness of the paint application. Very thick impasto layers will take much longer to cure than thin washes.
- Environmental Conditions: Drying times are affected by humidity and temperature. Colder, more humid environments will slow down the curing process.
Varnishing Your Acrylics
Varnishing provides an extra layer of protection for your acrylic paintings. It shields the surface from dust, UV light (if an archival varnish is used), and minor abrasions. It also helps to even out the sheen of the painting.
Types of Acrylic Varnishes:
- Gloss: Provides a shiny, reflective finish.
- Satin: Offers a subtle sheen, less reflective than gloss.
- Matte: Eliminates shine, giving a non-reflective, velvety appearance.
When to Varnish:
Wait until the acrylic paint is thoroughly dry and cured. This typically means waiting at least 72 hours after the last layer of paint has been applied, but ideally, waiting two weeks to a month is best for full curing.
Application Tips:
- Apply in a well-ventilated area.
- Use a soft, wide brush or spray varnish.
- Apply thin, even coats.
- Allow each coat to dry completely before applying the next.
Framing and Surface Protection
While not always necessary for temporary storage, framing can add a significant layer of protection, especially for long term art storage.
- Frames: A frame adds structural support and a barrier against direct contact with other surfaces. Ensure the frame doesn’t press directly onto the painted surface. Use a mat or spacer if necessary.
- Glass or Acrylic Sheets: For added protection against dust and physical damage, glass or acrylic sheets can be added to the frame. Ensure there is a slight gap between the painting’s surface and the glass/acrylic to prevent adhesion.
Ideal Storage Environments
Creating the right environment is paramount for painting preservation. Environmental factors can be the biggest enemy of your artwork.
Temperature and Humidity Control
Extreme temperature fluctuations and high humidity are detrimental to paintings.
- Temperature: Aim for a stable room temperature, ideally between 65-75°F (18-24°C). Avoid attics, basements, garages, or areas near heating/cooling vents, as these are prone to significant temperature swings.
- Humidity: Maintain a relative humidity level between 40-60%. High humidity can encourage mold growth and cause materials like canvas and wood to expand and contract, stressing the paint. Low humidity can make materials brittle.
Tips for Managing Environmental Factors:
- Climate-Controlled Spaces: The best option for serious collectors or long-term storage.
- Dehumidifiers/Humidifiers: Can be used in smaller storage areas to maintain optimal levels.
- Monitoring: Use a hygrometer/thermometer to keep track of temperature and humidity.
Light Exposure
Light, especially direct sunlight and fluorescent light, can cause pigments to fade over time.
- Avoid Direct Sunlight: Never store paintings where they will be exposed to direct sun.
- Minimize Artificial Light: Store paintings in dark areas or use UV-filtering glass/acrylic in frames.
Ventilation
Good airflow is important to prevent the buildup of moisture and potential mold growth. However, avoid placing paintings directly in drafty areas.
Methods for Storing Acrylic Paintings
The way you physically store your paintings depends on the number of pieces, their size, and the duration of storage. Proper art studio organization includes designated storage solutions.
Storing Paintings Vertically
Vertical storage is generally preferred as it reduces the risk of pressure damage.
- Art Racks and Easels: Dedicated art racks or sturdy easels can hold paintings upright.
- Shelving Units: Use sturdy shelves that can accommodate the weight and size of your paintings.
-
Protection Between Paintings: Always place a protective layer between stacked vertical paintings to prevent scratching and paint transfer.
- Glassine Paper: Acid-free and smooth, it’s ideal for protecting painted surfaces.
- Archival Cardboard or Foam Core: Cut to size, these can provide a rigid barrier.
- Bubble Wrap (with caution): If using bubble wrap, ensure the bubbles do not press directly onto the paint surface. Place a layer of glassine paper or acid-free tissue paper between the painting and the bubble wrap.
Storing Paintings Horizontally (with Caution)
Horizontal storage is less ideal, especially for multiple stacked paintings, as the weight can cause damage. If you must store them horizontally, follow these guidelines:
- Single Layer: Never stack more than two or three paintings horizontally, and only if they are of similar size and weight.
- Sturdy Support: Ensure the surface supporting the paintings is completely flat and stable.
- Protective Layers: Use glassine paper or archival cardboard between each painting.
- Avoid Weight: Do not place heavy objects on top of horizontally stored paintings.
Flat File Storage
For smaller works on paper or canvas boards, flat file cabinets are an excellent option.
- Archival Quality: Ensure the drawers and any folders used are acid-free and archival quality.
- Protection: Place each artwork in an archival sleeve or interleave with glassine paper.
- Avoid Overcrowding: Do not cram too many pieces into one drawer, as this can cause damage.
Packaging and Transport
If you need to move your paintings, proper packaging is essential to prevent damage.
Wrapping Individual Paintings
- Glassine Paper: Start by wrapping the entire painting surface with glassine paper.
- Bubble Wrap: Add a layer of bubble wrap around the glassine paper. Ensure the bubbles are not in direct contact with the paint.
- Cardboard Protection: Create corner protectors from sturdy cardboard.
- Outer Layer: Wrap the entire package securely in heavy-duty paper or plastic sheeting.
Boxing Paintings
- Sturdy Boxes: Use strong, appropriately sized boxes.
- Padding: Fill any empty space in the box with packing peanuts, foam, or crumpled paper to prevent shifting.
- Labeling: Clearly label the box as “Fragile” and indicate which side is up.
Storing Art Supplies
Beyond finished paintings, proper storage of art supplies storage also plays a role in successful acrylic painting. This includes keeping your paints, brushes, and mediums in good condition.
Acrylic Paints
- Tubes: Store acrylic paint tubes upright or horizontally in a cool, dry place away from direct sunlight. Ensure caps are tightly closed to prevent drying.
- Bottles/Jars: Similar to tubes, keep them sealed and in a stable environment.
Brushes
- Clean and Dry: Always clean your brushes thoroughly after use. Ensure they are completely dry before storing.
- Bristles Up: Store brushes upright with the bristles facing upwards to prevent bending. You can use brush holders or jars.
- Avoid Moisture: Do not store wet brushes in sealed containers, as this can lead to mold.
Mediums and Varnishes
- Airtight Seals: Ensure all bottles and jars are tightly sealed to prevent evaporation or contamination.
- Temperature Stability: Store these liquids away from extreme heat or cold, which can affect their properties.
Common Storage Mistakes to Avoid
Knowing what not to do is just as important as knowing what to do.
Stacking Paintings Directly on Top of Each Other
This is a common mistake that can lead to paint transfer, scratches, and pressure damage. Always use protective interleaving materials.
Storing in Direct Sunlight or Near Heat Sources
As mentioned, light and heat are major enemies of artwork. Even indirectly, heat from radiators or sunlight through a window can degrade your paintings over time.
Storing in Damp or Humid Environments
This is a breeding ground for mold and can also cause the canvas and stretcher bars to warp, potentially damaging the paint layer.
Using Non-Archival Materials
Standard packing tape, regular cardboard, or newspaper can leach acids and cause damage over time. Always opt for archival-quality materials when direct contact with the artwork is possible.
Forgetting About the Back of the Canvas
The back of the canvas is also susceptible to dust and damage. Consider covering it with archival paper or fabric for an extra layer of protection.
