Gouache, oil and acrylic paintings are highly durable. However, a few precautions should be taken to ensure that they will keep for a long time. We recommend that you avoid exposing them to direct light, in order to reduce their exposure to UV rays. Particular attention should be paid to their support in order to protect them from humidity; canvas and wooden supports are particularly sensitive to this element. We recommend that you avoid any sudden changes in temperature or humidity, which could lead to tension or loosening of the canvas, requiring the intervention of a framer.
