What are the challenges of maintaining outdoor marble animal sculptures?

Maintaining outdoor marble animal sculptures presents several challenges due to their exposure to natural elements. Weathering is a primary concern, as rain, snow, and temperature fluctuations can cause cracks, erosion, and discoloration over time. Pollution and acid rain further accelerate deterioration by chemically reacting with the marble's surface. Biological growth, such as moss and lichen, can also embed into the stone, requiring careful cleaning to avoid damage. Additionally, physical impacts from vandalism or accidental contact may lead to chips or breaks. Regular maintenance, including gentle cleaning and protective sealants, is essential to preserve these artworks, but it demands expertise to avoid harming the delicate marble. Without proper care, these sculptures risk losing their detail and structural integrity.
