Storing paintings, prior to shipping them, requires special conditions, especially if the artwork is priceless. Some of the most important aspects of storing paintings in a shipping warehouse, or storage facility include:
Making sure the storage area is cold, dry, dust free, and dark. Light, humidity, dirt, dust, and heat can all damage paintings.
Making sure the storage area has no windows where direct sunlight shines on the paintings.
Using wrappings, such as durable plastics, to protect your paintings while they are in storage.
Storing paintings in boxes, especially those made with cardboard, that are padded with extra cushioning.
