Proper storage and care of watercolor paintings will help preserve their brightness and integrity for many years.

Here are some recommendations:

Storage:

• Frame and Glass:

Frame the watercolor painting using a mat to prevent the painting from touching the glass.
Use UV-protective glass to minimize fading from sunlight.

• Environmental Conditions:

Store watercolor paintings in a dry, cool place with low humidity (ideally around 50%).
Avoid direct sunlight and extreme temperature fluctuations.

• Unframed Storage:

If the painting is unframed, store it flat in a portfolio or folder, protected from dust and light.
Use acid-free paper sheets between the paintings to prevent mechanical damage and acid degradation.

• Archival Materials:

Only use acid-free and archival materials for storage and framing to avoid chemical reactions that could damage the watercolor.

Care:

• Cleaning:

Do not clean watercolor paintings with a wet cloth or anything that can dampen the paint. If dust settles on the surface, gently brush it off with a soft brush.

• Condition Check:

Regularly check the condition of the paintings for mold, insects, and other damage. If problems are found, consult a professional conservator.

• Avoid Touching:

Try not to touch the surface of the watercolor painting with your hands to avoid leaving grease marks. It’s better to use cotton gloves.

Additional Tips:
Ventilation: Occasionally ventilate the storage area to prevent moisture buildup.
Insurance: If you have valuable watercolor paintings, consider insuring them against damage or theft.

By following these recommendations, you can keep your watercolor paintings in excellent condition for a long time.
