How to Care for Artwork at Home?

Bringing an artwork home is the beginning of a new relationship with it. Where the piece is displayed, how it is handled and the conditions surrounding it will influence how well it ages.

Learning how to care for artwork does not mean recreating the precisely controlled environment of a museum. In most homes, the greatest benefits come from simple preventive measures: avoiding direct sunlight, limiting rapid changes in humidity and temperature, using suitable framing and resisting the temptation to clean or repair a work without professional guidance.

These measures matter whether you own one painting or an established collection. The latest Art Basel and UBS Global Art Market Report estimates that the global art market reached US$59.6 billion in 2025, with approximately 41.5 million transactions. As works continue to move into new collections, responsible ownership involves more than acquisition. It includes documentation, preservation and thoughtful long-term care.

This artwork care guide explains how to protect paintings, works on paper, photographs, sculpture and mixed-media art while allowing them to remain a meaningful part of your home.

What Does Art Preservation Mean?

Art preservation focuses on preventing or slowing deterioration before extensive treatment becomes necessary.

It differs from restoration. Preservation manages risks such as light, humidity, heat, pollutants, pests, handling and water. Restoration or conservation treatment addresses damage that has already occurred and should normally be undertaken by a qualified professional.

The most effective approach is preventive:

• Place artwork in an appropriate location.
• Maintain reasonably stable environmental conditions.
• Use conservation-conscious framing and storage materials.
• Handle and move works as little as possible.
• Inspect the collection regularly.
• Record any changes in condition.
• Contact a conservator before damage becomes more serious.

Preventive care is usually safer, less intrusive and less costly than repairing avoidable damage.

1. Understand the Artwork’s Materials

Before deciding how to preserve artwork, identify what it is made from.

An oil painting on canvas responds differently to its environment than a watercolour, photograph, wooden sculpture or digital installation. Contemporary art may incorporate materials that were never designed to last indefinitely, including plastics, adhesives, textiles, organic matter, found objects and electronic components.

Review the invoice, certificate of authenticity and any care instructions supplied by the artist or gallery. Record:

• Medium and support
• Date of creation
• Dimensions and weight
• Framing or mounting system
• Artist-provided display instructions
• Light sensitivity
• Recommended temperature and humidity
• Cleaning restrictions
• Installation requirements
• Replaceable or variable components
• Contact details for the artist, gallery or fabricator

If the medium is described only as “mixed media,” ask for more detail. Knowing what a work contains is essential to making informed care decisions.

2. Choose a Safe Display Location

The position of an artwork can have a greater effect on its longevity than almost any later intervention.

Before installation, consider what happens in the space throughout the day and across different seasons.

Avoid displaying artwork:

• In direct sunlight
• Immediately above a working fireplace
• Next to a radiator or heating vent
• Directly beneath an air-conditioning outlet
• On a damp or poorly insulated exterior wall
• Near a stove, sink or food-preparation area
• In a bathroom with frequent changes in humidity
• Where plants are watered or misted
• In a narrow, heavily used hallway
• Where doors, furniture or bags may strike it
• Within easy reach of children or pets

A location may appear safe in the morning but receive strong sunlight in the afternoon. Observe the wall over a complete day before installing a sensitive piece.

The Canadian Conservation Institute advises against placing paintings near open windows, doors, heating and cooling ducts or radiators because these areas experience rapid environmental changes. Even the traditional place of honour above a fireplace can expose a painting to heat, dryness and soot.

3. Protect Artwork from Light

Light damage is cumulative and irreversible. It may cause pigments to fade, paper to discolour, photographs to shift in tone and certain materials to become brittle.

Both daylight and artificial light can cause deterioration. Direct sunlight is particularly damaging because it combines intense visible light, ultraviolet radiation and heat.

To reduce exposure:

• Keep artwork out of direct sunlight.
• Use curtains, blinds or shutters during the brightest hours.
• Consider UV-filtering film for windows.
• Use UV-filtering glazing where appropriate.
• Choose LED lighting that produces little heat or ultraviolet radiation.
• Avoid attaching hot picture lights directly to frames.
• Turn display lights off when the room is not in use.
• Rotate especially sensitive works rather than displaying them continuously.

Works on paper, watercolours, textiles, colour photographs and artworks containing fugitive dyes are particularly light-sensitive. The Canadian Conservation Institute emphasizes that light damage to works on paper cannot be reversed.

UV-filtering glass or acrylic can reduce ultraviolet exposure, but it does not eliminate damage caused by visible light. The duration and intensity of exposure still matter.

4. Maintain Stable Temperature and Humidity

Artwork is generally more vulnerable to rapid environmental changes than to modest, gradual seasonal variation.

Canvas, wood, paper and textiles absorb and release moisture as relative humidity changes. They expand and contract at different rates, potentially causing warping, cracking, rippling, lifting paint or weakened adhesives.

The Canadian Conservation Institute identifies a stable relative-humidity range of approximately 40–60% as generally safe for many paintings, with 50% often used as a central museum reference point. It also considers a room-temperature range of approximately 16–25°C acceptable for paintings. These are broad guidelines rather than universal specifications; highly sensitive or unusual materials may require narrower conditions.

In a home:

• Aim for stability rather than constant adjustment.
• Avoid sudden changes in temperature or humidity.
• Keep art away from vents, radiators and working fireplaces.
• Do not display vulnerable works against cold or damp exterior walls.
• Use a digital hygrometer to monitor temperature and relative humidity.
• Address water leaks and condensation promptly.
• Avoid over-humidifying a room during winter.
• Consult a conservator before creating a sealed microclimate.

Canadian winters can be particularly dry inside heated homes. According to the Institute’s current preventive-care guidance for paintings, paint layers can become increasingly brittle at low relative humidity; below approximately 35%, some paintings face a greater risk of cracking, lifting paint and paint loss.

High humidity creates different risks, including mould, corrosion, swelling and distortion. Basements, attics and garages are therefore usually unsuitable for displaying or storing art.

5. Use Protective Framing

A frame is more than a decorative border. Proper framing protects vulnerable edges, supports the artwork and reduces risks during handling and display.

Paintings

A suitable frame can provide structural support and protect a painting’s edges. Paintings should be secured correctly without nails driven into the stretcher. For valuable or vulnerable works, ask a professional framer or conservator about adding a rigid backing board.

A backing board can protect the reverse of a canvas from impact, dust and rapid humidity changes. Installation must be done correctly, however; improper attachment can damage the work.

If a painting is glazed:

• The glass or acrylic should not touch the paint surface.
• Spacers should maintain a safe separation.
• The frame must be strong enough to support the added weight.
• Glazing should be appropriate for the artwork’s scale and surface.

Works on Paper

Watercolours, drawings, prints and photographs should generally be framed using conservation-quality materials.

Look for:

• Acid-free or conservation-grade mat board
• Reversible hinges
• A window mat or spacer that keeps glazing away from the artwork
• UV-filtering glass or acrylic
• An archival backing board
• A sealed dust cover where appropriate

Never allow the artwork to touch the glazing. Condensation or pressure can cause adhesion, distortion and surface damage.

Avoid permanently dry-mounting an original work unless the artist intended that presentation. Irreversible adhesives can discolour paper and make future conservation difficult.

6. Handle Artwork Carefully

Handling is one of the most common causes of accidental damage.

Before moving a work:

1. Inspect it for loose paint, unstable components or a weak frame.
2. Remove jewellery, watches and anything that could scratch the surface.
3. Clear the route and open doors in advance.
4. Prepare the destination before lifting the work.
5. Ask another person to assist with large, heavy or awkward pieces.

When carrying a framed painting, support it with one hand underneath and another at the side. Never lift it by the hanging wire or the top of the frame.

Do not:

• Touch the painted surface.
• Press against the back of a canvas.
• place fingers between the stretcher and canvas.
• Carry a work by projecting decorative elements.
• Lean unprotected artwork against furniture.
• Stack paintings directly against one another.
• Move art in extreme heat or cold without suitable packing.

Use clean, dry hands for most paintings and framed works. Nitrile gloves may be appropriate for photographs, metals and objects that readily retain fingerprints. Cotton gloves can reduce dexterity and may catch on rough or fragile surfaces, so they are not suitable for every medium.

When uncertain, ask the gallery, artist or conservator for medium-specific handling advice.

7. How to Clean Artwork Safely

Collectors frequently ask how to clean artwork. The safest general answer is: clean the surrounding frame and display area carefully, but do not attempt to clean the artwork’s surface unless a conservator has confirmed an appropriate method.

Paint surfaces can be unexpectedly sensitive. Water, household cleaners, saliva, solvents, oils and commercial “restoration” products may dissolve paint, alter gloss, drive dirt further into the surface or leave permanent residues.

Do not use:

• Water or damp cloths on an exposed artwork
• Household cleaning sprays
• Alcohol or solvents
• Bread, potatoes or other traditional home remedies
• Feather dusters that may catch on raised paint
• Compressed air
• Vacuum cleaners directly on the artwork
• Brushes on flaking, powdery or textured surfaces
• Varnish or coating products not authorized by a conservator

The Canadian Conservation Institute advises that cleaning a painting’s surface is best left to a professional conservator, because the correct procedure depends on the work’s materials, construction and condition.

For routine home care:

• Keep the room clean to reduce dust accumulation.
• Inspect artwork rather than touching it unnecessarily.
• Dust the top and outer edges of a stable frame with a soft, clean cloth.
• Support the frame so it does not shift while being dusted.
• Clean glass or acrylic only according to the framer’s instructions.
• Apply any approved glazing cleaner to the cloth—not directly to the frame.
• Prevent moisture from entering around the glazing or frame edges.
• Never press against glazing that is close to the artwork.

Acrylic glazing scratches easily and may react poorly to some glass cleaners. Ask the framer which product is suitable.

If the artwork itself appears dirty, yellowed or discoloured, contact a conservator. What looks like dirt may be an altered varnish, intentional surface treatment or a change within the materials.

8. How to Store Artwork

Understanding how to store artwork is essential even if most of your collection remains on display.

Choose an interior, climate-stable area away from water pipes, drains, exterior doors and direct sunlight. Avoid attics, basements, garages and sheds, where temperature and humidity can fluctuate dramatically.

Storing Paintings

• Store paintings vertically rather than flat.
• Keep them raised off the floor.
• Use padded separators between works.
• Prevent frames and surfaces from touching.
• Protect the front and back with rigid material where appropriate.
• Do not wrap paintings directly in plastic for indefinite storage without professional advice.
• Avoid placing weight against a canvas.
• Label protective coverings rather than attaching labels to the artwork.
• Ensure stored works cannot slide or tip.

The Canadian Conservation Institute recommends protective wrapping and rigid support on both sides when paintings are stored vertically in a stable interior area.

Storing Works on Paper

Unframed works on paper should be placed flat in conservation-quality folders, portfolios or archival boxes. Interleaving and enclosure materials must be suitable for the particular medium.

Do not:

• Roll works unless their size and condition make rolling necessary.
• Use pressure-sensitive tape.
• Place newsprint, cardboard or acidic tissue against the artwork.
• Overfill boxes or drawers.
• Store paper directly on the floor.

Storing Photographs

The Library of Congress identifies a good storage environment as one of the most important preservation measures for photographs. Photographs should be protected from light, dust and handling in suitable paper or plastic enclosures.

Photographic materials vary considerably. Traditional prints, instant photographs, film negatives and contemporary digital prints may require different enclosures and conditions. Consult a photograph conservator for valuable, deteriorating or unusual material.

Storing Sculpture and Objects

Place sculpture on stable, padded shelving capable of supporting its weight. Avoid crowding and leave enough space to lift each object safely.

Use inert padding or mounts rather than unstable foams, adhesive putties or materials that may stain. Cover works loosely when appropriate, while allowing sufficient airflow and avoiding contact with fragile surfaces.

9. Protect Paintings from Physical Damage

Knowing how to protect paintings involves more than controlling light and humidity.

Use hanging hardware rated for more than the artwork’s total weight. For larger or valuable pieces, consider professional installation and security fittings.

Additional precautions include:

• Use two appropriate wall hooks when suitable to improve stability.
• Confirm that the wall and anchors can support the work.
• Secure the lower edge in high-traffic or vibration-prone areas.
• Avoid hanging heavy work above beds or seating without professional installation.
• Add bumpers where frames may rub against walls.
• Use barriers or strategic furniture placement around floor sculpture.
• Check hanging hardware periodically.
• Never rely on deteriorated wire, loose screws or a single small nail.

Earthquake-prone locations, homes with young children and public-facing spaces may require specialized security hardware.

10. Inspect and Document the Collection

Caring for an art collection includes learning what each work normally looks like.

Inspect the collection every three to six months. Use consistent lighting and compare the work with earlier photographs.

Look for:

• New cracks or lifting paint
• Canvas distortion
• Loose frames or hanging hardware
• Discolouration or fading
• Rippling paper
• Condensation inside glazing
• Insect activity
• Mould or unusual odours
• Corrosion
• Loose or detached components
• Water stains
• Changes in digital or electronic performance

Do not repeatedly touch a suspicious area to test it. Photograph the change, note the date and contact a conservator.

Maintain a collection record containing:

• Artist, title and date
• Medium and dimensions
• High-resolution images
• Purchase invoice
• Certificate of authenticity
• Provenance
• Condition reports
• Framing and installation details
• Artist care instructions
• Insurance information
• Conservation and treatment history
• Current location

Updated photographs and records can be invaluable after accidental damage, theft or an insurance claim.

Caring for Different Types of Art

Oil and Acrylic Paintings

Avoid direct sunlight, rapid environmental changes and pressure against the canvas. Do not apply cleaning products or additional varnish. Contact a conservator if paint begins to lift, crack or flake.

Unvarnished acrylic can remain soft and attract dust. Its surface can also be sensitive to cleaning, making preventive protection particularly important.

Watercolours, Drawings and Prints

These works are often highly sensitive to light and should be displayed behind conservation-quality glazing. Use archival mats and reversible hinges. Consider rotating especially sensitive pieces to reduce cumulative exposure.

Pastel and charcoal surfaces are easily disturbed. Do not tap, brush or place them face down.

Photographs

Protect photographs from prolonged light, high humidity, pollutants and fingerprints. Use suitable enclosures and glazing. Do not clean photographic surfaces without specialist advice.

Sculpture

The correct care depends on the material. Bronze, wood, stone, ceramic, plaster, resin and mixed-media sculpture can respond very differently to water, cleaning products and handling.

Do not polish a sculpture unless the artist, gallery or conservator has confirmed that polishing is appropriate. Surface patina may be intentional and historically important.

Textile Art

Textiles can fade, stretch and attract pests. Keep them away from direct sunlight, use appropriate supports and inspect periodically for insect activity. Heavy textiles may require specially designed mounting systems rather than being suspended from a few points.

Digital and Time-Based Art

Preserve original files, installation instructions, software information, passwords and certificates. Maintain redundant backups in separate locations and document the approved display equipment.

Ask whether screens, projectors or other components may be replaced and whether the artist has specified acceptable models or formats. Digital art preservation involves maintaining both the work’s data and its intended viewing experience.

What to Do If Artwork Is Damaged

If damage occurs, remain calm and avoid improvised repairs.

If a Work Falls

Do not immediately rehang it. Place it in a safe, stable location and check for loose paint, broken glazing, frame damage or distortion. Keep glass fragments away from the artwork and contact a professional.

If a Painting Tears

Do not apply tape, adhesive or a patch. Protect the area from contact and consult a conservator promptly. A fresh tear may become more difficult to align if treatment is delayed.

If Artwork Gets Wet

Move the work away from the source of water only if it can be done safely. Do not rub, wipe or apply heat. Keep detached fragments and labels. Contact a conservator, insurer and restoration professional as soon as possible.

If You Find Mould

Isolate the work from the rest of the collection. Avoid brushing or vacuuming it, as this may spread spores. Mould can pose a health risk, so seek professional advice before handling or treatment.

If Paint Is Flaking

Keep the work vertical and minimize vibration. Do not press the flakes back into place or apply adhesive. Avoid moving the painting unless necessary and contact a conservator.

When Should You Contact a Conservator?

Seek professional advice when you notice:

• Flaking or lifting paint
• Tears, punctures or deep scratches
• Active mould
• Water damage
• Severe warping or distortion
• Insect infestation
• Unstable or broken frames
• Detached components
• Significant fading or discolouration
• A cloudy or yellowed varnish
• Adhesion to glazing
• Corrosion
• Failing electronic components
• Any proposed cleaning or restoration of a valuable work

A conservator can examine the work, identify its materials and recommend options based on its condition and intended use. The least invasive appropriate treatment is generally preferable.

Preservation Begins with Attention

The central principle of art preservation is simple: prevent damage before treatment becomes necessary.

Thoughtful placement, stable conditions, suitable framing and careful handling can protect most artworks from their greatest everyday risks. Just as importantly, regular observation allows subtle changes to be recognized before they develop into serious problems.

Learning how to care for art is part of becoming its steward. The goal is not to keep an artwork hidden from daily life, but to create conditions in which it can be seen, enjoyed and passed forward responsibly.

G.Z Contemporary Art Gallery can advise collectors on artist-specific care, framing, installation, documentation and appropriate professional conservation support. When a work becomes part of your home, its care becomes part of the collection’s continuing story.

Frequently Asked Questions About Artwork Care

What is the best way to care for artwork at home?

Provide a stable environment, avoid direct sunlight, use suitable framing, handle works carefully and inspect them regularly. Professional advice should be sought before cleaning or repairing an artwork.

What humidity level is safe for artwork?

Many paintings are generally safest within a stable relative-humidity range of approximately 40–60%. Different materials may require different conditions, and stability is especially important. Consult a conservator for valuable, fragile or mixed-media works.

Can I clean an oil painting with water?

No. Water may interact with surface dirt, varnish, paint or earlier restoration materials. Cleaning should be performed by a qualified paintings conservator.

Can I dust a painting?

Dusting an exposed painting can scratch the surface, catch on textured paint or dislodge unstable material. Keep the surrounding space clean and ask a conservator whether the individual work can be safely dusted.

Does UV-protective glass stop all fading?

No. UV-filtering glazing reduces ultraviolet exposure, but visible light can still cause fading. Limit the intensity and duration of all light exposure.

Can paintings be stored flat?

Paintings are generally stored vertically with appropriate protection and separators. Stacking them flat may place damaging weight and pressure on frames and painted surfaces.

Should artwork be stored in plastic?

Plastic may offer short-term protection during properly planned transport, but inappropriate long-term wrapping can trap moisture or contact sensitive surfaces. Use material-specific archival enclosures and obtain professional advice for valuable works.

How often should an art collection be inspected?

A visual inspection every three to six months is a useful starting point. Works in unstable environments or made from sensitive materials may require more frequent monitoring.

Does home insurance automatically cover art?

Not always. Coverage limits, exclusions and valuation requirements vary. Discuss the collection with an insurance professional and maintain current invoices, photographs, valuations and condition records.
