The short answer
Immediate Steps to Rescue Wet Paintings
If a painting gets wet, move it to a dry, safe area immediately. Lay it flat, face up, on a clean, dry surface. Do not rub the surface, as this can grind in dirt or smear paint. Gently blot any standing water from the surface with a soft cloth or paper towel.
How Different Art Materials Respond to Water
Oil paintings on canvas are more resilient to brief water exposure than other types. The paint itself may resist water, but the canvas can shrink, warp, or become stained. Watercolor and acrylic paintings are far more vulnerable, as the water-soluble pigments can run or lift from the paper or board almost immediately upon contact.
The substrate, or surface, matters greatly. Paper and cardboard backing swell and distort quickly, which can cause the artwork to cockle or tear. Wooden panels can warp and crack. In a humid climate, any trapped moisture can quickly lead to mold growth on organic materials.
- Oil Paint on Canvas: May survive brief contact, but canvas is vulnerable to stretching, warping, and mold.
- Watercolor on Paper: Highly susceptible; pigments can bleed and paper can disintegrate rapidly.
- Acrylic Paint: Binder is water-resistant when dry, but prolonged wetness can cause adhesion failure.
- Paper Artworks (Prints, Drawings): Ink may run and paper can become extremely fragile when wet.
- Gilded or Varnished Surfaces: Water can cause clouding, blooming, or irreversible dullness in the finish.
- Mixed Media: Different materials react at different rates, complicating the drying process.
The Drying Process and Avoiding Mold
Proper drying is a slow, controlled process. Rapid drying with high heat from hair dryers or heaters can cause paint to crack, canvas to shrink dramatically, or glue to fail. Instead, aim for a stable, cool, and dry environment with good air circulation. Use fans to move air around the room, but not pointed directly at the artwork.
Mold is the greatest threat after the initial water event. It can grow on the paint, canvas, paper, and backing within 24 to 48 hours in damp conditions. Mold causes permanent stains and can weaken materials. If you see any fuzzy growth or smell a musty odor, you need to consult a professional art conservator or a mold remediation specialist immediately.
When to Call a Professional Art Conservator
For any artwork of significant monetary or sentimental value, contacting a professional art conservator is the safest course. The specialists have the training, tools, and controlled environment to stabilize, clean, and repair water-damaged art. They can perform treatments like flattening warped canvases, removing stains, and consolidating flaking paint that are beyond a homeowner's ability.
A conservator will assess the damage, provide a treatment plan, and discuss what outcomes are possible. They work to preserve the original material as much as possible. The cost for this specialized service varies widely and depends on the artwork's size, medium, and the extent of the damage.
Documenting Damage for Insurance Purposes
Before moving or attempting any cleanup, take clear, well-lit photographs and videos of the damaged artwork from multiple angles. Document its condition, any visible water lines, and the surrounding area. This visual evidence is crucial for filing an insurance claim. Keep a written list detailing each piece, its artist, medium, and an approximate value if known.
Contact your insurance company to report the damage and understand your policy's coverage for fine art. Policies vary, and your insurer decides what is covered. Provide them with your documentation. If you hire a conservator, keep all receipts and reports. Do not discard any damaged pieces until your insurer gives you permission.
- Take comprehensive photos and video before touching anything.
- Note the artwork's title, artist, medium, and approximate value.
- Capture the context, showing where the damage occurred in the room.
- Save any separated pieces, like flaking paint or torn paper, in a bag.
- Keep a detailed log of all communications with your insurance company.
- Retain all receipts and reports from any professionals you consult.

Can I use a hairdryer to dry a wet painting?
No, using a hairdryer is not recommended. The concentrated heat can cause paint to blister, crack, or become brittle. It can also force moisture deeper into the layers or cause rapid shrinkage and warping. Allow the artwork to air dry slowly at room temperature with good circulation.
What should I do if mold grows on my painting?
If you see mold, isolate the artwork to prevent spores from spreading. Do not attempt to clean it yourself, as improper methods can set the stains or damage the paint. Contact a professional art conservator or a mold remediation specialist who has experience with delicate items for safe assessment and cleaning.
Will my homeowner's insurance cover water damage to art?
It might, but you must check your specific policy. Fine art often has special limits or requires a separate rider. Document all damage thoroughly with photos before any cleanup. Policies vary, and your insurer decides what is covered. Report the loss promptly and provide all requested documentation to your insurance company.
