How to Care for and Preserve Your Canvas Paintings

Cover: AI-generated editorial illustration.

A hand-painted canvas is built to be lived with — but it isn't indestructible. Light, humidity, heat, dust, and the way you handle it all shape how the surface looks years from now. The good news is that preserving a painting takes only a few simple, consistent habits, and the routine differs slightly depending on whether your canvas arrives already stretched or rolled.

What actually damages a canvas painting

Canvas paintings can use cotton or linen supports; SeeGart uses artist-grade linen canvas. Fabric, paint, and any surface treatment respond differently to their environment. Physical pressure, unsuitable cleaning, dampness, and strong light can cause damage. If the paint is lifting, cracking, sticky, soft, or flaking, avoid treatment and seek professional advice.

Protect it from light

Light damage is cumulative and varies with the materials and exposure. Both visible light and ultraviolet radiation can matter, so reducing direct sun is more useful than assuming artist-grade paint cannot fade.

• Hang art on walls that avoid strong direct sun, especially hot afternoon light.
• If a sunny spot is unavoidable, draw blinds during peak hours or rotate pieces between rooms.
• If glazing (glass or acrylic) is ever used, it must not touch the painted surface — adequate spacing is essential. Most stretched and framed canvases are displayed without glazing, unlike works on paper.

Control humidity and temperature

Canvas expands and contracts as the air changes. Sustained dampness encourages mold and can loosen the fabric; extreme dryness and heat can make paint brittle. Stability matters more than any single number — aim to keep conditions reasonably steady, at roughly 40–60% relative humidity (around 50% is a good target).

• Avoid steamy bathrooms and kitchens, and keep art away from radiators, air vents, fireplaces, and appliances that throw heat.
• Keep pieces away from damp exterior walls, and point humidifiers or dehumidifiers away from the artwork.

Dusting and cleaning the safe way

Cleaning is not a routine that every painting should receive. A stable-looking surface may still be fragile. The Canadian Conservation Institute’s cleaning precautions recommend expert assessment: even light dusting can dislodge paint. For a SeeGart work, email customer-service@seegart.com with the product link and finish option before treating the surface.

• For hand-painted and textured work, avoid rubbing or brushing without guidance for that surface. Raised paint can catch a cloth or brush, and an apparently small mark may need a conservator’s assessment.
• For prints or coated pieces, follow the maker’s instructions. If the coating is unknown, do not assume a brush, cloth, or cleaning fluid is suitable.
• Never spray water, glass cleaner, furniture polish, solvents, or any cleaning product onto or near the canvas, and don't rub at marks.
• Avoid feather dusters (they can catch and scratch) and never vacuum the painted surface directly.

Leave stains and attached dirt for a paintings conservator to assess. Do not test a succession of household cleaning methods.

Caring for thickly textured (impasto) paintings

Raised paint needs protection from pressure and contact. For display, keep light and heat exposure in mind; side lighting is not automatically harmless. Ask for care guidance for the specific surface instead of using a brush by default. For more on the technique, see What Is Impasto Technique?, and browse Textured Wall Art.

Stretched or framed canvas: hanging and storage

For a canvas that arrives already stretched over bars or set in a frame:

• Hang it from proper picture hooks rated for the weight, and check the hanging hardware and cord periodically.
• Make sure the artwork cannot rub against the wall or surrounding objects, and leave a little airflow behind it.
• When storing a stretched or framed piece, keep it upright (never flat under weight) in a dry, stable room away from light and damp exterior walls.
• Always carry it by the frame or the sides of the stretcher — never by the hanging wire — and keep fingers off the painted front.

Rolled or unstretched canvas: arrival and storage

If you order a rolled canvas, it travels in a protective tube with a margin of blank fabric around the image. Treat the roll gently, because forcing it can mark fresh or thick paint.

• If the package has arrived in very cold weather, leave it wrapped and let it gradually come to room temperature before opening, to reduce the risk of condensation on a cold surface.
• Follow the maker’s unpacking instructions and let a qualified framer assess rolled work before stretching. Do not force it flat, fold, iron, steam, or apply heat.
• Keep weights and packing materials from pressing on the painted face. If curling remains, ask a qualified framer or conservator about preparation rather than forcing it flat.
• An unstretched canvas waiting to be framed may be stored flat if it is well supported and nothing presses on the painted face; keep packaging materials from contacting the image, and never press bubble wrap directly against the paint.

To decide between a rolled and a framed finish before you order, see Rolled vs. Framed Canvas, and check delivery timelines in our Shipping Policy.

Moving and packing any canvas

• Handle the work by its frame or stretcher bars and avoid touching the image, since skin oils can mark the surface over time.
• Use a non-contact protective setup wherever possible — protect the corners and edges, and keep wrapping materials from adhering to, pressing on, or leaving residue on raised or soft paint.
• Avoid rubber bands, tape, or cling film against the painted surface, and don't pack artwork tightly against other objects.

When to call a professional conservator

Some conditions should never be treated at home. Contact a qualified paintings conservator if you notice cracking or flaking, paint that feels sticky or unusually soft, mold or mildew, the canvas sagging or pulling away from its stretcher, tears or punctures, or persistent yellowing or discoloration. Trying to fix these yourself usually makes a clean repair harder. If a brand-new piece arrives damaged in transit, don't treat it — photograph it and contact us within 48 hours.

Frequently asked questions

How often should I dust a canvas painting?

There is no fixed schedule. Ask for advice for the artwork’s surface before dusting; a brush is not automatically safe even when paint looks intact. Avoid unnecessary handling.

Can I clean a canvas with water or glass cleaner?

No. Do not use water, glass cleaner, polish, or solvents on the painted face. Ask the maker or a conservator about the particular surface instead of substituting a household cleaning method.

Can I hang a canvas in a bathroom or kitchen?

Avoid steamy, poorly ventilated bathrooms and spots near a stove or sink. A dry, well-ventilated room is safer; if you use a humid room, keep the piece well away from direct steam and check it periodically.

Is it safe to hang art above a fireplace or radiator?

It's best avoided — fireplaces and radiators create heat, dryness, and temperature swings that can stress both canvas and paint over time.

How do I remove the curl from a rolled canvas?

Follow the unpacking instructions and ask a qualified framer to assess persistent curl. Do not weight, iron, steam, heat, or force the painting flat.

Do textured or impasto paintings need special care?

Raised paint needs particular protection from contact: avoid pressing, wiping, or brushing it without surface-specific advice, and keep glazing or packaging from touching the paint.

A package arrived in freezing weather — should I open it immediately?

Leave it wrapped and let it gradually reach room temperature first. Opening a cold canvas into warm, moist air can cause condensation; slow acclimation protects the surface.
