How does eucalyptus wood’s tannin content affect nearby concrete or stone surfaces?
Eucalyptus wood is known for its high tannin content, a natural compound that can leach out over time, especially when exposed to moisture. When eucalyptus wood comes into contact with or is placed near concrete or stone surfaces, the tannins can migrate and cause noticeable staining or discoloration. This effect is more pronounced in porous materials like untreated concrete or certain types of stone, as they absorb the tannins more readily. Rainwater or irrigation can accelerate this process by washing the tannins onto adjacent surfaces. To prevent this, sealing the wood or using barriers between the wood and concrete/stone can help minimize staining. Regular cleaning and maintenance of the affected surfaces may also reduce long-term damage.
