Core Environmental Parameter Requirements
Temperature Control: The ideal storage temperature is stable at 18-22℃. In summer, this can be relaxed to 21-24℃. Avoid drastic temperature fluctuations to prevent abnormal expansion and contraction of the canvas fibers, which can cause damage.
Humidity Control: Relative humidity should be maintained stably at 50%-60%, with a maximum of 60%. High humidity environments require dehumidification to prevent mold growth.
Key Storage Precautions
Avoid direct sunlight to prevent ultraviolet rays from damaging the canvas fibers. Also, keep away from areas with high humidity, such as kitchens and bathrooms.
You can apply two thin layers of natural beeswax dissolved in turpentine to the back of the canvas to prevent moisture penetration and improve its moisture resistance.
Do not paste two canvases side-by-side. For long-term storage, it is recommended to wrap the canvas in acid-free paper before applying an outer protective layer to prevent the canvas from sticking together and leaving marks.
