How to preserve different types of art

Fine art is a significant investment and a source of cultural value, whether it’s displayed in your home, a gallery, or kept in storage. In New Zealand, coastal conditions, humidity, and seasonal temperature changes require special attention to preservation. Understanding the needs of different materials and media is key to ensuring your collection remains in pristine condition for generations.

Panel paintings, especially those on wood, are highly sensitive to environmental changes. New Zealand weather can be unpredictable, with humidity shifts during wet periods and dry indoor air in winter. Wood panels may crack or warp if exposed to fluctuating temperatures or humidity. To protect these works, stabilise your environment to around 20°C and maintain humidity at approximately 45%. If central humidification isn’t available, use dehumidifiers in humid regions and humidifiers in dry climates. Avoid placing panel paintings near windows, heaters, or air conditioning vents, as these areas are prone to rapid environmental changes.

Oil paintings on canvas are susceptible to cracking and deformation, especially in New Zealand’s variable climate. Canvas supports can stretch or shrink, and paint layers may separate if exposed to extreme conditions.

Keep your collection in rooms with stable temperature and humidity, and avoid hanging paintings above fireplaces or in direct sunlight. If your home lacks climate control, consider investing in portable systems to maintain consistency.

Paper-based artworks, including prints and drawings, are vulnerable to acid deterioration and foxing—rust-coloured spots caused by humidity and impurities. Many commercial papers used in New Zealand contain acidic elements, which accelerate deterioration. To minimise damage, frame your pieces using archival materials and acid-free backing. Store paper art in climate-controlled environments and avoid mounting on acidic boards. If foxing appears, consult a professional conservator for cleaning and restoration.

Ceramic and glass vases, bowls, and vessels are prone to breakage, scratches, and cracks. When moving these items, always carry them by the base rather than the neck or lip. Display them in secure cabinets or on sturdy shelves, away from high-traffic areas and out of reach of children and pets. In regions prone to earthquakes or tremors, consider using museum putty or adhesive pads to anchor fragile pieces.

Sculptures and three-dimensional art require stable display surfaces. Place them on stands or shelves that can support their weight and size, and avoid positioning them near doorways or busy corridors. When cleaning, use gentle methods and avoid bumping or knocking the artwork. For outdoor sculptures, consider the impact of sun, rain, and salt air—regular maintenance and protective coatings may be necessary.

New Zealand sunlight is intense and can quickly fade photographs, watercolours, works with coloured inks, and textiles. Avoid using picture lights mounted on frames, as they generate heat and pose a risk of damage. Display these works on interior walls, away from direct sunlight and plumbing. Use recessed or ceiling-mounted lighting, keep curtains drawn, and turn off lights when not in use. Install UV-filtering film on windows and rotate artwork in and out of storage to limit exposure.

Improper framing can cause irreversible damage to works on paper and textiles. Use museum-quality, archival materials such as acid-free ragboard or blueboard for mounting and backing. Ensure adhesives are archival and reversible. Matting and archival hinging prevent items from adhering to glazing, especially in humid environments.

Artworks with powdery or loose pigments, like pastels or charcoal, are vulnerable to static build-up and contamination. Frame these pieces with UV glass or museum glass and use a protective dust-seal backing. This prevents dirt, dust, and insect intrusion, which can be a concern in New Zealand homes.

Even with careful preservation, accidents and environmental events can occur. Standard home and contents insurance often falls short for high-value art collections. Consider specialised  contents or valuable articles coverage, such as Chubb Masterpiece^®, which offers comprehensive insurance for fine art and collectibles. These policies provide broader coverage and expert support, , ensuring your collection is safeguarded against loss, damage, and theft.

By understanding the unique challenges posed by New Zealand’s climate and lifestyle, and by applying best practices in storage, display, and maintenance, you can protect your art collection for years to come. With the added security of Chubb Masterpiece insurance, you can enjoy your collection knowing it’s insured by a policy crafted for life’s most treasured works.
