The invisible enemy: a specialist guide to protecting your art from weather damage during art transport
There’s a moment every artist and collector knows well. It’s that feeling in your gut when you hand over a piece you love for art transport. You’ve ensured it’s packed securely against bumps and shocks, but what about the threats you can’t see?
At Nimart, we’ve spent years mastering the complex challenges of art transport. And we can tell you that the most significant risks on any journey aren't the potholes in the road, but the invisible enemies traveling right alongside the art: humidity and temperature.
These silent forces can cause slow, devastating, and often irreversible damage. But they don’t have to. In this post, we’re pulling back the curtain to show you what your art is up against and how a professional approach to art transport makes all the difference.
Why Your Art is Secretly at War with the Weather
Most art is made from organic materials—canvas, wood, paper, natural pigments. These materials are "hygroscopic," which is a scientific way of saying they behave like a sponge. They absorb moisture from humid air and release it into dry air. This constant, subtle breathing is where the trouble begins.
The Damage Done: Humidity's Two Faces
Fluctuating humidity is a primary cause of damage during art transport. Both extremes are dangerous.
Threat #1: High Humidity (The Swell and Mold) When the air is damp, your artwork soaks it in. This can lead to:
Rippling and Slack: Canvases can lose their tension and begin to sag. Works on paper will buckle and warp.
Foxing: Those ugly, rust-colored spots on old prints and drawings? That’s foxing, a type of mold growth spurred on by moisture.
Mold Outbreaks: In the worst cases, active mold can grow directly on the piece, staining it permanently and eating away at the material.
Threat #2: Low Humidity (The Shrink and Crack) Dry air is just as destructive. It aggressively pulls moisture out of the artwork, causing:
Brittleness: Paper and old canvas can become incredibly fragile, making them susceptible to tears.
Cracking and Flaking: As the canvas or wood support shrinks, the less-flexible layers of paint on top can’t keep up. This stress causes them to crack and flake off.
Warping: Wooden stretcher bars or panels can twist and warp as they dry out, putting immense strain on the entire piece.
Temperature: The Fast-Track to Decay
Temperature acts as an accomplice to humidity, often speeding up the damage. Without climate control during the art transport leg of its journey, the artwork inside experiences every single one of those environmental shocks.
The Problem with Heat: High heat can soften varnishes, making them sticky and attracting dirt. It can accelerate the chemical reactions that cause colors to fade and materials to decay.
The Shock of Cold: Extreme cold makes everything brittle. Paint, gesso, and wood become fragile and highly susceptible to cracking under the slightest vibration.
The Nimart Solution: A Climate-Controlled Fortress for Your Art Transport
So how do we fight an enemy that’s in the very air itself? We don’t leave it to chance. We build a multi-layered fortress specifically for art transport.
1. The First Line of Defense: Climate-Controlled Art Transport Vehicles This is non-negotiable for professional art transport. Our trucks are mobile, climate-controlled vaults. We maintain a consistent, museum-standard environment inside, typically around 70°F (21°C) and 50% relative humidity, no matter what the weather is doing outside.
2. The Personal Safe Room: Custom Climate Crating Every crate we build is a micro-environment. For sensitive pieces, we use museum-grade insulation and vapor barriers (a special lining that stops moisture transfer). This seals the crate, creating a stable bubble of air that travels with the artwork.
3. The 24/7 Watchmen: Active Monitoring For high-value or exceptionally fragile shipments, we place small, sophisticated data loggers inside the crate to track temperature and humidity throughout the entire art transport process. This gives us—and you—a complete record confirming your piece was never under stress.
Don't Leave Your Legacy to Chance
When you entrust us with your artwork, you're handing over a part of a legacy. Protecting it from the obvious dangers is standard for any shipment, but protecting it from the invisible ones is what defines a true art transport professional.
