How does cedar’s natural tannins affect adjacent concrete surfaces in sculptures?
Cedar wood, prized for its durability and aromatic qualities, is often used in outdoor sculptures. However, its natural tannins can negatively impact adjacent concrete surfaces. When exposed to moisture, these tannins leach out and migrate into porous concrete, leading to unsightly brownish stains. Over time, the acidic nature of tannins may also weaken the concrete's surface, causing minor erosion or pitting. This reaction is particularly noticeable in humid or rainy climates where water facilitates tannin transfer. Artists and conservators must consider protective barriers or sealants to prevent long-term damage when combining cedar and concrete in sculptural works. Regular maintenance, such as cleaning and resealing, can mitigate these effects and preserve the artwork's integrity.
