How to Care for a Watercolour Painting

Watercolour paintings are more delicate than many other mediums. The paper, pigments and mounting materials all play a role in how well the artwork lasts over time.

If properly framed and displayed, a watercolour can remain vibrant for decades. Here are some tips from our workshop on how to care for a watercolour painting.

Keep it out of direct sunlight

UV exposure is one of the primary causes of fading. Even indirect sunlight can gradually reduce colour intensity. If possible:

• Hang away from windows

• Avoid strong spotlights

• Use UV-filtering glazing

Specialised glazing can significantly reduce UV transmission.

Use Acid-Free Materials

Paper is sensitive to acidic environments. Acid-free mounts and backing boards prevent:

• Yellowing

• Foxing

• Gradual deterioration

Older frames often contain cardboard backings that cause long-term damage.

Maintain Stable Humidity

Watercolours are vulnerable to moisture. Avoid keeping your works in:

• External walls prone to condensation

• Bathrooms

• Kitchens

Fluctuating humidity can cause warping and mould growth.

Avoid Direct Contact With Glass

The artwork should never touch the glass. A mat or spacer creates separation and prevents:

• Condensation damage

• Sticking

• Surface abrasion

Proper mounting techniques are essential for long-term preservation. We can help you choose the right technique to ensure the artwork stays off the glass.

Handle Carefully

Always hold the artwork by the edges. Avoid touching the painted surface, as oils from hands can leave marks over time.

Consider Conservation Framing

For original or sentimental works, conservation-grade framing provides additional protection through:

• Archival materials

• UV-filtering glazing

• Proper mounting techniques
