What are the effects of bird droppings on untreated stone surfaces?
Bird droppings can have severe effects on untreated stone surfaces over time. The acidic nature of bird excrement can lead to chemical erosion, causing the stone to weaken and lose its structural integrity. Additionally, droppings can cause unsightly discoloration and staining, which may become permanent if not addressed promptly. The high nitrogen content in bird waste can also promote the growth of algae and lichens, further accelerating deterioration. To protect untreated stone, regular cleaning and the application of protective sealants are recommended. Ignoring the issue can result in costly repairs or replacements due to irreversible damage.
